Outline) First, outline of a first embodiment according to the present disclosure will be described. For example, work to be performed in association with capturing of video content, a video, or the like, for TV broadcasting (or for distribution on the Internet) covers a wide range, and creators bear a great burden. More specifically, the creators are required to judge a timing for start or end of imaging, framing (work for determining a position and a size in a camera frame of a subject for whom an image is captured), switching of cameras, video correction processing and the like such as white balance processing, luminance processing or blur correction processing and the like, and the creators consume enormous resources to perform these kinds of work. Further, there is a great need for metadata (for example, data indicating a subject, a scene, an imaging environment, or the like) regarding video content. For example, in a case where desired video content is searched for from enormous pieces of video content, or in a case where a desired scene is searched for among video content, a user can efficiently perform search using metadata regarding the video content. However, in a current situation, to generate metadata regarding video content, it is often the case that the user is required to manually perform input work upon imaging, and, if the user forgets this work, the user cannot obtain the metadata regarding video content. Further, in recent years, service which allows video content to be distributed using a simple method actively appears. For example, a user can easily distribute video content by uploading video content which is personally captured to a predetermined web site. However, in a case where the user personally creates video content for these kinds of service, it is not easy to perform various kinds of work as described above alone or with a few people. In view of these backgrounds, a technology of enabling work in association with creation of video content to be easily and more efficiently realized is desired. The above-described Patent Literature 1 discloses a technology of enabling control of processing of distribution, accumulation, or the like, of a video on the basis of a tag ID by detecting the tag ID of a tag apparatus provided to a subject. However, as described above, because the content of imaging control based on the tag ID is fixed, and the user cannot freely set or change the content of imaging control, it is difficult for the technology, or the like, disclosed in Patent Literature 1 to address a wide variety of user's needs regarding imaging. In view of the circumstances described above, a discloser of the present case has created a technology according to the present disclosure. An imaging apparatus according to the present disclosure includes an imaging unit configured to perform imaging, a communication unit configured to perform communication with a tag apparatus located within a communication range corresponding to an imaging range, and an imaging control unit configured to control processing regarding imaging on the basis of information regarding the tag apparatus (such as, for example, a tag ID and scene information) and pre-setting by a user. By this means, the user can set in advance content of imaging control based on the tag ID detected through communication with the tag apparatus, and the imaging apparatus can appropriately perform imaging control on the basis of the setting. Embodiments of the present disclosure will be described in detail below. (1.2. System Configuration Example) The outline of the first embodiment according to the present disclosure has been described above. Subsequently, a configuration example of an imaging system according to the present embodiment will be described with reference to FIG. 1. As illustrated in FIG. 1, the imaging system according to the present embodiment includes an imaging apparatus 100, a variable directivity antenna apparatus 110, an imaging control apparatus 200, and a tag apparatus 300. (Imaging Apparatus 100) The imaging apparatus 100 is an imaging apparatus which captures an image of a subject 10 who wears (or carries) the tag apparatus 300, and can control processing regarding imaging on the basis of the detected tag ID of the tag apparatus 300 and the pre-setting by the user. More specifically, first, the user sets in advance content of imaging control to be executed in a case where a tag ID using the imaging control apparatus 200, and the imaging control apparatus 200 provides setting information to the imaging apparatus 100. By this means, the imaging apparatus 100 can appropriately execute processing on the basis of the pre-setting in a case where a tag ID is detected. While the content of imaging control to be executed by the pre-setting includes, for example, start or end of imaging, video correction processing and the like such as white balance processing, luminance processing or blur correction processing and the like, the content is not limited to these. By this means, the user can cause the imaging apparatus 100 to perform desired imaging control. If detection of a tag ID by the imaging apparatus 100 is more specifically described, the imaging apparatus 100 has a communication range corresponding to an imaging range of the own apparatus, and includes the variable directivity antenna apparatus 110 which performs communication with the tag apparatus 300 located within this communication range. For example, the imaging range refers to an angle of view of the imaging apparatus 100, the communication range refers to an angle at which communication is possible when the variable directivity antenna apparatus 110 is set as a reference, and it is assumed that the angle of view is smaller than the angle at which communication is possible. Here, relationship between the imaging range and the communication range will be described with reference to FIG. 2 and FIG. 3. FIG. 2 is a plan view (overhead view) illustrating aspect where the imaging apparatus 100 captures an image of the subject 10. The imaging range of the imaging apparatus 100 is a range within the angle of view 20, and the communication range is a range within the angle at which communication is possible (note that, in FIG. 2, the variable directivity antenna apparatus 110 is omitted). Further, as illustrated in FIG. 2, it is assumed that the angle of view 20 is smaller than the angle at which communication is possible 30. Further, FIG. 3 is a side view (view viewed from edge-on) illustrating aspect where the imaging apparatus 100 captures an image of the subject 10 (note that, also in FIG. 3, the variable directivity antenna apparatus 110 is omitted). Also in the side view, it is assumed that the angle of view 20 is smaller than the angle at which communication is possible 30. By this means, the variable directivity antenna apparatus 110 can not only acquire a tag ID by performing communication with the tag apparatus 300 in a case where the subject 10 is located within the imaging range, but also can acquire a tag ID in a similar manner if the subject 10 is located within the communication range although the subject 10 is located outside the imaging range. Therefore, the imaging apparatus 100 can grasp the subject 10 located outside the imaging range and within the communication range as well as the subject 10 located within the imaging range by the tag ID being provided from the variable directivity antenna apparatus 110. Then, the imaging apparatus 100 causes the imaging range to coordinate with the communication range. More specifically, the imaging apparatus 100 expands the communication range by controlling the variable directivity antenna apparatus 110 in a case where the imaging range expands, and, inversely, narrows the communication range in a case where the imaging range narrows. By this means, the imaging apparatus 100 can appropriately maintain relationship between the imaging range and the communication range even in a case where the angle of view 20 is changed as in a case of zooming-up, or the like, in response to user operation. Note that the relationship between the imaging range and the communication range is not limited to the relationship illustrated in FIG. 2 and FIG. 3. For example, the imaging range may be substantially the same as the communication range (in other words, the angle of view 20 may be substantially the same as the angle at which communication is possible 30), or the imaging range may be smaller than the communication range (in other words, the angle of view 20 may be smaller than the angle at which communication is possible 30). Further, the imaging range and the communication range may be expressed with values other than the angle of view 20 and the angle at which communication is possible 30. Further, the imaging apparatus 100 can appropriately acquire metadata regarding video content by recording information regarding the detected tag ID in association with the captured image data. While, currently, there are technologies of automatically generating metadata by analyzing captured image data, in the technologies, not only processing load is high, but also there is a case where metadata is not appropriately generated in a case where an image of a subject which is behind an obstacle is captured. Meanwhile, in the present embodiment, because metadata is generated on the basis of a wireless signal from the tag apparatus 300, it is possible to suppress processing load to be lower than that in a case where captured image data is analyzed, and it is possible to appropriately generate metadata even if an image of the subject 10 which is behind an obstacle is captured, if the wireless signal from the tag apparatus 300 is received at the variable directivity antenna apparatus 110. Note that a type of the imaging apparatus 100 is not particularly limited. For example, the imaging apparatus 100 may be any apparatus if the apparatus can capture a video, such as a portable video camera (including, for example, a video camera for business use or a video camera for home use), a stationary video camera (including, for example, a security camera), and an in-vehicle video camera (including, for example, a dashboard camera). (Variable Directivity Antenna Apparatus 110) As described above, the variable directivity antenna apparatus 110 is a communication apparatus connected to the imaging apparatus 100. Further, the variable directivity antenna apparatus 110 has directivity as a result of receiving sensitivity of a wireless signal from a set direction being higher than receiving sensitivity of wireless signals from other directions, and, as described above, has the communication range corresponding to the imaging range of the imaging apparatus 100. Further, because the variable directivity antenna apparatus 110 can change an orientation direction to an arbitrary direction by control by the imaging apparatus 100, as described above, it is possible to cause the communication range to coordinate with the imaging range. Further, the variable directivity antenna apparatus 110 also function as a communication unit which performs wireless communication with the tag apparatus 300, and acquires a tag ID, or the like, through the wireless communication. More specifically, the variable directivity antenna apparatus 110 acquires a tag ID by receiving a wireless signal transmitted from the tag apparatus 300. Note that information which is communicated by the variable directivity antenna apparatus 110 and the tag apparatus 300 in a wireless manner is not limited to the tag ID. For example, by the tag apparatus 300 including information, or the like, regarding a state of the own apparatus (such as, for example, battery information and information regarding an environment where the own apparatus is placed) in a wireless signal, the variable directivity antenna apparatus 110 may acquire these kinds of information and use these kinds of information for arbitrary processing. Further, inversely, the variable directivity antenna apparatus 110 may include information regarding a state of the own apparatus or the imaging apparatus 100 (such as, for example, information of a communication scheme which can be supported by the own apparatus and information regarding an environment where the imaging apparatus 100 is placed), information regarding a state of the tag apparatus 300 (such as, for example, information indicating that the tag apparatus 300 is located within the angle of view and information indicating that the tag apparatus 300 is not located within the angle of view), or the like, in a wireless signal and may transmit the wireless signal to the tag apparatus 300. By this means, for example, the tag apparatus 300 can notify the subject 10 of these kinds of information through vibration, a video, sound, or the like, on the basis of the received wireless signal. Further, a wireless communication scheme between the variable directivity antenna apparatus 110 and the tag apparatus 300 is not particularly limited. For example, wireless communication between the variable directivity antenna apparatus 110 and the tag apparatus 300 may be realized through Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like. Further, a type of the variable directivity antenna apparatus 110 and a method for changing an orientation direction are not particularly limited. Further, the number of the variable directivity antenna apparatuses 110 or aspect where the variable directivity antenna apparatus 110 is provided at the imaging apparatus 100 is not particularly limited. (Imaging Control Apparatus 200) The imaging control apparatus 200 is an information processing apparatus to be used for controlling the imaging apparatus 100. More specifically, the imaging control apparatus 200 generates control information on the basis of user operation, and controls the imaging apparatus 100 by transmitting the information to the imaging apparatus 100. Further, the user can set content of imaging control to be executed in a case where a tag ID is detected using the imaging control apparatus 200. An example of the content of imaging control is as described above. Further, the imaging control apparatus 200 is an apparatus which can reproduce or edit video content captured by the imaging apparatus 100. Note that, while it is assumed that the imaging control apparatus 200 is, for example, a smartphone 210 or a tablet personal computer (PC) 220 as illustrated in FIG. 1, the imaging control apparatus 200 is not limited to these. More specifically, the imaging control apparatus 200 may be an arbitrary information processing apparatus including a notebook PC, a desktop PC, an agent apparatus, a wearable apparatus, or the like. (Tag Apparatus 300) The tag apparatus 300 is an information processing apparatus which is worn (or carried) by the subject 10 and performs wireless communication with the variable directivity antenna apparatus 110. More specifically, when the tag apparatus 300 is activated, by the tag apparatus 300 transmitting wireless signals including information of the tag ID, or the like, at predetermined time intervals, the variable directivity antenna apparatus 110 can receive the wireless signals in a case where the tag apparatus 300 is located in the communication range of the variable directivity antenna apparatus 110. As described above, information to be communicated by the tag apparatus 300 and the variable directivity antenna apparatus 110 in a wireless manner is not limited to the tag ID. Further, transmission intervals of the wireless signals by the tag apparatus 300 are not particularly limited. Further, the tag apparatus 300 may receive a wireless signal transmitted from the variable directivity antenna apparatus 110 as well as transmit a wireless signal. Further, a type of the tag apparatus 300 is not particularly limited. For example, the tag apparatus 300 may be any apparatus if the apparatus can be worn or carried by a user, such as a smartphone, an arbitrary wearable apparatus (for example, a wristwatch type, spectacle type, accessory type, cloth type wearable apparatus, or the like) and a pin microphone. The configuration example of the imaging system according to the present embodiment has been described above. Note that the above-described configuration described with reference to FIG. 1 is merely an example, and the configuration of the imaging system according to the present embodiment is not limited to the example. For example, part of functions of the imaging apparatus 100 may be provided at the variable directivity antenna apparatus 110 or the imaging control apparatus 200. For example, software which provides part of the functions of the imaging apparatus 100 (for example, application, or the like, in which a predetermined application programming interface (API) is used) may be executed on the variable directivity antenna apparatus 110 or the imaging control apparatus 200. Further, the number of respective apparatuses which constitute the imaging system may be changed as appropriate. The configuration of the imaging system according to the present embodiment can be flexibly transformed in accordance with specifications and operation. (1.3. Functional Configuration Example of Imaging Apparatus 100 and Peripheral Equipment) Subsequently, a functional configuration example of the imaging apparatus 100 according to the present embodiment and peripheral equipment of the imaging apparatus 100 will be described with reference to FIG. 4. As illustrated in FIG. 4, the imaging apparatus 100 is connected to the variable directivity antenna apparatus 110, a lens 120 and a magnifying optical apparatus 130. Further, the variable directivity antenna apparatus 110 includes an antenna control unit 111 and a reception information processing unit 112. Further, the lens 120 includes an information output unit 121. Further, the magnifying optical apparatus 130 includes an information output unit 131. Further, the imaging apparatus 100 itself includes an information input unit 101, a control unit 102, a communication unit 103, an imaging unit 104 and a storage unit 105. (Variable Directivity Antenna Apparatus 110) The variable directivity antenna apparatus 110 is a communication apparatus which is connected to the imaging apparatus 100 and performs wireless communication with the tag apparatus 300. Because outline of the variable directivity antenna apparatus 110 has been described above, description will be omitted. (Antenna Control Unit 111) The antenna control unit 111 is a functional component which controls the communication range of the variable directivity antenna apparatus 110. More specifically, the control unit 102 of the imaging apparatus 100 determines the communication range of the variable directivity antenna apparatus 110 on the basis of the angle of view of the imaging apparatus 100, and provides control information for making a notification of the determined content to the antenna control unit 111. Then, the antenna control unit 111 controls the communication range of the variable directivity antenna apparatus 110 on the basis of the control information. Note that a control method of the communication range is not particularly limited, and an arbitrary publicly known technology can be used. For example, the variable directivity antenna apparatus 110 includes a plurality of antenna elements (array elements) arranged in a linear shape, a planar shape, a curved shape, or the like, and the antenna control unit 111 may realize control of the communication range by controlling power feeding, or the like, to the respective antenna elements. Further, the variable directivity antenna apparatus 110 may realize control of the communication range by a movable parabola antenna of which direction can be changed being provided. (Reception Information Processing Unit 112) The reception information processing unit 112 is a functional component which performs processing regarding a wireless signal received from the tag apparatus 300. For example, the reception information processing unit 112 estimates an arrival direction of the wireless signal and an isolation distance from a transmission source on the basis of a difference in received strength, phases, or the like, when a plurality of antenna elements receives the wireless signal. By this means, the reception information processing unit 112 can function as a position estimating unit which estimates a position of the tag apparatus 300 which has transmitted the wireless signal. The reception information processing unit 112 provides information regarding an estimation result of the position of the tag apparatus 300 to the control unit 102 of the imaging apparatus 100. While the information regarding the estimation result of the position of the tag apparatus 300 can be, for example, information indicating relative positional relationship between the variable directivity antenna apparatus 110 and the tag apparatus 300, the information is not limited to this. Further, the reception information processing unit 112 extracts a tag ID, or the like, included in the wireless signal received from the tag apparatus 300 and provides the tag ID, or the like, to the control unit 102 of the imaging apparatus 100. Note that the information to be provided from the reception information processing unit 112 is not limited to these. For example, the reception information processing unit 112 may provide received strength information of the wireless signal to the control unit 102. (Lens 120, Information Output Unit 121) The lens 120 is a detachable interchangeable lens which is used at the imaging apparatus 100 with interchangeable lenses. A type of the lens 120 is not particularly limited if the lens has a communication function for performing communication with the imaging apparatus 100. The information output unit 121 of the lens 120 is a functional component which transmits information regarding the lens 120 (hereinafter, referred to as “lens information”) to the imaging apparatus 100. For example, the information output unit 121 transmits position information, or the like, of a lens unit provided at the lens 120 to the imaging apparatus 100 as the lens information. Note that information to be transmitted from the information output unit 121 to the imaging apparatus 100 is not limited to this. (Magnifying Optical Apparatus 130, Information Output Unit 131) The magnifying optical apparatus 130 is a functional component which is attached on the imaging apparatus 100 side of the lens 120, and can expand the angle of view. While the magnifying optical apparatus 130 can be, for example, a wide converter lens, or the like, the magnifying optical apparatus 130 is not limited to this. The information output unit 131 of the magnifying optical apparatus 130 is a functional component which transmits information regarding the magnifying optical apparatus 130 (hereinafter, referred to as “magnifying apparatus information”) to the imaging apparatus 100. For example, the information output unit 131 transmits information regarding the angle of view (or a focal length), or the like, to the imaging apparatus 100 as the magnifying apparatus information. Note that information to be transmitted from the information output unit 131 to the imaging apparatus 100 is not limited to this. (Imaging Apparatus 100) The imaging apparatus 100 is an apparatus which captures an image of the subject 10 who wears (or carries) the tag apparatus 300. Because the outline of the imaging apparatus 100 has been described above, description will be omitted. (Information Input Unit 101) The information input unit 101 is a functional component to which the lens information and the magnifying apparatus information are input through predetermined communication with the information output unit 121 of the lens 120 and the information output unit 131 of the magnifying optical apparatus 130. The information input unit 101 provides the input these kinds of information to the control unit 102. (Control Unit 102) The control unit 102 is a functional component which generally controls the overall processing to be performed by the imaging apparatus 100. For example, the control unit 102 can calculate the angle of view on the basis of the lens information and the magnifying apparatus information provided from the information input unit 101. Note that a calculation method of the angle of view is not particularly limited. Further, the control unit 102 may calculate the angle of view through analysis of the captured image data, or the like, instead of using these kinds of information. Further, the control unit 102 can also adjust the angle of view on the basis of user operation, or the like. In this case, the control unit 102 generates control information for realizing a desired angle of view and transmits the control information to the lens 120 or the magnifying optical apparatus 130 (a functional component which transmits the control information is not illustrated), to thereby control lens positions, or the like, of these functional components. Then, the control unit 102 determines the communication range (such as an angle at which communication is possible) of the variable directivity antenna apparatus 110 on the basis of the angle of view, generates control information for making a notification of the determined content, and provides the control information to the variable directivity antenna apparatus 110, to thereby control the communication range of the variable directivity antenna apparatus 110. Further, the control unit 102 determines whether or not the tag apparatus 300 is located within the angle of view on the basis of the information regarding the estimation result of the position of the tag apparatus 300 provided from the reception information processing unit 112 of the variable directivity antenna apparatus 110. As described above, the information regarding the estimation result of the position of the tag apparatus 300 is, for example, information indicating relative positional relationship between the variable directivity antenna apparatus 110 and the tag apparatus 300, or the like. Here, because the relative positional relationship between the variable directivity antenna apparatus 110 and the imaging apparatus 100 is known, the control unit 102 can determine whether or not the tag apparatus 300 is located within the angle of view on the basis of the information regarding the estimation result of the position of the tag apparatus 300. The control unit 102 also functions as an imaging control unit which controls processing regarding imaging on the basis of the tag ID provided from the reception information processing unit 112 in a case where it is determined that the tag apparatus 300 is located within the angle of view. More specifically, because the control unit 102 grasps content of imaging control based on the tag ID on the basis of the setting information provided in advance from the imaging control apparatus 200, the control unit 102 can control processing regarding imaging on the basis of the tag ID provided from the reception information processing unit 112. For example, the control unit 102 can control start, end, or the like, of imaging processing on the basis of the provided tag ID. Further, in a case where the imaging unit 104 generates captured image data, the control unit 102 can perform video correction processing, or the like, on the captured image data on the basis of the provided tag ID. Note that the content of imaging control based on the tag ID is not limited to these. Further, respective types of imaging control may be performed at any timing before imaging, during imaging or after imaging. Further, if the tag apparatus 300 can recognize an imaging scene using any method including sensing, or the like, the control unit 102 may acquire information regarding the scene (scene information) from the tag apparatus 300 and may perform control similar to imaging control based on the tag ID on the basis of the scene information. Further, the control unit 102 also functions as a recording unit which records the provided tag ID in predetermined file data (for example, extensible markup language (XML) file data) and records the file data and the captured image data in association with each other. Here, an example of the file data generated by the control unit 102 will be described with reference to FIG. 5. FIG. 5 illustrates XML file data 40 as an example of the file data, and information regarding the tag ID is recorded in data 41 in the XML file data 40. For example, by “Metaspname=“Tag1”spcontent=“BOY”/”, information indicating that the tag apparatus 300 having a tag ID of “Tag1” is included in the captured image data, and the tag ID indicates “BOY”, is recorded (in other words, information indicating that the subject 10 in the character of a boy who wears the tag apparatus 300 having a tag ID of “Tag1” is included in the captured image data is recorded). Note that content of the file data is not limited to that illustrated in FIG. 5. Further, a method for associating the file data with the captured image data is not particularly limited. For example, the control unit 102 may associate the file data with the captured image data by recording identification information of the captured image data in the file data, recording identification information of the file data in the captured image data, or the like. The control unit 102 causes the file data and the captured image data to be stored by providing these kinds of data to the storage unit 105. Note that processing by the control unit 102 is not limited to the above-described processing. For example, the control unit 102 may acquire the file data and the captured image data stored in the storage unit 105 on the basis of a request from the imaging control apparatus 200 and may provide the file data and the captured image data to the imaging control apparatus 200 via the communication unit 103. Further, the control unit 102 may control processing which is typically performed at a video camera, or the like. (Communication Unit 103) The communication unit 103 is a functional component which controls various kinds of communication with the imaging control apparatus 200. For example, in a case where the user sets in advance content of imaging control based on the tag ID using the imaging control apparatus 200, the communication unit 103 receives the setting information from the imaging control apparatus 200. Further, upon imaging, the communication unit 103 receives various kinds of control information to be used for imaging from the imaging control apparatus 200. Further, after imaging, when the user confirms the captured image data using the imaging control apparatus 200, the communication unit 103 transmits the captured image data and the file data associated with the captured image data to the imaging control apparatus 200. Note that information communicated by the communication unit 103 and a case where the communication unit 103 performs communication are not limited to these. (Imaging Unit 104) The imaging unit 104 is a functional component which executes imaging processing by being controlled by the control unit 102. For example, the imaging unit 104 includes a lens system including an imaging lens, a diaphragm, a zoom lens, a focusing lens, or the like, a drive system which causes the lens system to perform focusing operation and zooming operation, a solid-state imaging element array which performs photoelectric conversion on imaged light obtained at the lens system to generate captured image data, or the like. The solid-state imaging element array may be realized with, for example, a charge coupled device (CCD) sensor array, or a complementary metal oxide semiconductor (CMOS) sensor array. The imaging unit 104 provides the captured image obtained by the solid-state imaging element array to the control unit 102. (Storage Unit 105) The storage unit 105 is a functional component which stores various kinds of information. For example, the storage unit 105 stores the above-described setting information, file data, captured image data, or the like, or stores a program, a parameter, or the like, to be used by respective functional components of the imaging apparatus 100. Note that the information stored in the storage unit 105 is not limited to these. The functional configuration example of the imaging apparatus 100 and the peripheral equipment of the imaging apparatus 100 has been described above. Note that the functional components described above using FIG. 4 are merely an example, and the functional components of the imaging apparatus 100 and the peripheral equipment of the imaging apparatus 100 are not limited to the example. For example, the imaging apparatus 100 and the peripheral equipment of the imaging apparatus 100 do not necessarily have to include all the functional components illustrated in FIG. 4. Further, the functional components of the imaging apparatus 100 and the peripheral equipment of the imaging apparatus 100 can be flexibly transformed in accordance with specifications and operation. (1.4. Functional Configuration Example of Imaging Control Apparatus 200) The functional configuration example of the imaging apparatus 100 according to the present embodiment and the peripheral equipment of the imaging apparatus 100 has been described above. Subsequently, a functional configuration example of the imaging control apparatus 200 according to the present embodiment will be described with reference to FIG. 6. As illustrated in FIG. 6, the imaging control apparatus 200 includes a control unit 201, an input unit 202, an output unit 203, a communication unit 204, and a storage unit 205. (Control Unit 201) The control unit 201 is a functional component which generally controls overall processing to be performed by the imaging control apparatus 200. For example, the control unit 201 can control activation and stop of respective components including the output unit 203 such as a display and a speaker on the basis of input, or the like, performed by the user using the input unit 202. Note that control content of the control unit 201 is not limited to these. For example, the control unit 201 may control processing which is typically performed at a smartphone 210, a tablet PC 220, a notebook PC, a desktop PC, an agent apparatus, a wearable apparatus, or the like. (Input Unit 202) The input unit 202 is a functional component which accepts input by the user. For example, the input unit 202 includes input means such as a mouse, a keyboard, a touch panel, a button, a switch and a microphone, and the user can perform control of the imaging apparatus 100, pre-setting, or the like, of content of imaging control to be executed in a case where a tag ID is detected, by using these kinds of input means. The input unit 202 provides the input content to the control unit 201. Note that the input means provided at the input unit 202 is not particularly limited. (Output Unit 203) The output unit 203 is a functional component which outputs various kinds of information. For example, the output unit 203 includes display means such as a display or sound output means such as a speaker, and displays a screen to be used for pre-setting of the imaging control content, the captured image data, or the like, at the display, or the like, or outputs sound using the speaker, or the like, on the basis of control by the control unit 201. Note that the output means provided at the output unit 203 is not particularly limited. Here, an output example of the output unit 203 will be described with reference to FIG. 7 to FIG. 10. First, an example of a setting screen 50 for associating the tag ID of the tag apparatus 300 with a target to which the tag apparatus 300 is provided (such as, for example, a performer and a scene set) will be described with reference to FIG. 7. The user inputs the tag ID which is to be associated and a target to which the tag apparatus 300 is to be provided in a tag ID text box 51 and a tag apparatus provision target text box 52 on the setting screen 50. Note that, while an input method is not particularly limited, the user may perform input by tapping a software keyboard 53 displayed by the output unit 203. Note that the setting screen for association is not limited to this and can be changed as appropriate. For example, as illustrated in FIG. 8, the user may perform input using a tag ID pull-down 54 displayed by the output unit 203. More specifically, the tag ID of the tag apparatus 300 which is being detected by the variable directivity antenna apparatus 110 may be displayed at the tag ID pull-down 54 so as to be able to be selected. By this means, the user can perform input more easily. Note that, as well as the tag ID, a target to which the tag apparatus 300 is to be provided may be input through pull-down. Subsequently, a setting screen 60 for imaging control to be executed on the basis of the tag ID will be described with reference to FIG. 9. The user inputs the tag ID to be set in a tag ID text box 61 of the setting screen 60 and makes setting using a setting pull-down 62 of imaging control to be executed. Note that, as illustrated in FIG. 9, a pull-down 63 for performing more detailed setting may be used. Note that various kinds of setting described with reference to FIG. 7 to FIG. 9 may be realized by capturing of a predetermined file (such as, for example, a comma separated values (CSV) file) instead of being input on a screen. By this means, even in a case where there are a number of pieces of setting content, the user can perform various kinds of setting more easily. Subsequently, an example of a screen to be used upon browsing of the captured image data will be described with reference to FIG. 10. FIG. 10 illustrates an example of a screen 70 which displays a thumbnail of the captured image data on the basis of a detection status of the tag ID. As described above, predetermined file data is generated on the basis of the detection status of the tag ID, and the file data is associated with the captured image data. The output unit 203 of the imaging control apparatus 200 can create a thumbnail of the captured image data associated with each piece of file data and can display the thumbnail. As illustrated in FIG. 10, the output unit 203 displays a thumbnail 71 of the captured image data associated with each piece of file data and displays a tag ID 72 included in the captured image data (in the drawing, tag IDs of “T1” and “T2” are indicated) by analyzing the file data associated with the captured image data of the selected thumbnail 71. By this means, the user can easily recognize what is included in each piece of the captured image data. Note that the respective screens in FIG. 7 to FIG. 10 may be displayed by an output unit of an apparatus other than the imaging control apparatus 200. (Communication Unit 204) The communication unit 204 is a functional component which controls various kinds of communication with the imaging apparatus 100. For example, in a case where the user sets in advance content of imaging control based on the tag ID, the communication unit 204 transmits the setting information to the imaging apparatus 100. Further, upon imaging, the communication unit 204 transmits various kinds of control information to be used for imaging to the imaging control apparatus 200. Further, after imaging, when the user confirms the captured image data using the imaging control apparatus 200, the communication unit 204 receives the captured image data and the file data associated with the captured image data from the imaging apparatus 100. Note that information communicated by the communication unit 204 and a case where the communication unit 204 performs communication are not limited to these. (Storage Unit 205) The storage unit 205 is a functional component which stores various kinds of information. For example, the storage unit 205 stores the above-described setting information, control information, captured image data, or file data associated with the captured image data, or the like, or stores a program, a parameter, or the like, to be used by respective functional components of the imaging control apparatus 200. Note that the information stored in the storage unit 205 is not limited to these. The functional configuration example of the imaging control apparatus 200 has been described above. Note that the functional components described above using FIG. 6 are merely an example, and the functional components of the imaging control apparatus 200 are not limited to the example. For example, the imaging control apparatus 200 does not necessarily have to include all the functional components illustrated in FIG. 6. Further, the functional components of the imaging control apparatus 200 can be flexibly transformed in accordance with specifications and operation. (1.5. Functional Configuration Example of Tag Apparatus 300) The functional configuration example of the imaging control apparatus 200 according to the present embodiment has been described above. Subsequently, a functional configuration example of the tag apparatus 300 according to the present embodiment will be described with reference to FIG. 11. As illustrated in FIG. 11, the tag apparatus 300 includes a control unit 301, an input unit 302, an output unit 303, a communication unit 304, and a storage unit 305. (Control Unit 301) The control unit 301 is a functional component which generally controls overall processing to be performed by the tag apparatus 300. For example, the control unit 301 can control activation and stop of respective components including the output unit 303 such as a display and a speaker on the basis of input, or the like, performed using the input unit 302. Note that control content of the control unit 301 is not limited to these. For example, the control unit 301 may control processing which is typically performed at a smartphone, a tablet PC, a wearable apparatus, or the like. (Input Unit 302) The input unit 302 is a functional component which accepts input. For example, the input unit 302 includes input means such as a touch panel, a button, a switch and a microphone, and the user can perform
