The items herein may be, for example, data files of photographs, videos, music, or texts. However it should be noted that the item is not limited to them. 
 The item selection module 47 is a software module to decide the items to be used for the multimedia presentation to be created. The item selection module 47 provides three ways for item selection, the auto selection, the selection based on user-designated period, and the manual selection. Details feature of the item selection module 47 will be described later. 
 The presentation-creating module 48 creates a new multimedia presentation using the items that have been selected by the item selection module 47. As the items may be data files of photographs, videos, or music, the multimedia presentation to be created can also be a data file containing these multimedia contents. For example, the created multimedia presentation may be a movie file, in which the selected pictures are presented at the beginning of the movie, then the selected videos are played after the pictures, while the selected music are played as a background music. The presentation creating module 48 can automatically edit and adjust the length of the multimedia presentation to suit to the transmitting by, i.e. MMS. The created multimedia presentation can be replayed with the video player 21. In addition to this example, a lot of embodiments are possible to create various styles of data files by combining, synthesizing, or editing still images, videos, sounds, and texts. 
 In the following, the aspect of creating a multimedia presentation by the imaging phone 1 will be described in order. FIG. 5 is a flow chart illustrating a sequence of creating the multimedia presentation in this embodiment. 
 In step 10, the user accesses various items, and such events are recorded in the access history by the event record module 46. In this step, the user may listen to the music file downloaded from the PC or Internet with the music player 19, watch pictures or videos taken by the camera module 7, or send a data file such as a sound, an image, a movie or a text as an attachment of MMS. The event record module 46 records the time that the user accessed to these files in the access record together with names of these files and the file types (image, video, audio, or so). In another embodiment, the event record module 46 may be arranged to record the kind of events together with them. 
 Step 20 is the step in which the items to be used for the new presentation file are decided by the item selection module 47. This step will be described below in detail using FIG. 6. 
 FIG. 6 is a flow chart illustrating flows for deciding items used for a presentation to be created. At first, the item selection module 47 is started up in step S100. The item selection module 47 is made active when the user chooses icon 15 from the Menu screen of the imaging phone 1. A start-up screen of the item selection module 47 is shown in FIG. 7(a). 
 In FIG. 7(a), a text of “Presentation Creator”, which is the name of the multimedia presentation-creating software 39, is displayed at position 51 in the LCD screen 2. The letters of “Menu” are displayed at the lower left 52 in the screen, which shows that the user can access the menu of the item selection module 47 by pressing the left key 4. Also, the letters of “Exit” are displayed at the lower right 53 of the screen, which shows that the user can terminate the operation of the item selection module 47 by pressing the right key 3. 
 Referring to FIG. 6, and moving to step S110. This step is to choose ways of deciding the items. When the user pushes the left key 4 from the screen shown in FIG. 7(a), the menu 54 emerges from under the screen, and the view of the LCD screen 2 changes as shown in FIG. 7(b). The menu 54 comprises menu options of “Auto” 56, “Set Period” 57, “Manual” 58, and “Setting” 59. The user can choose either of these options by manipulating the function key 3. If “Auto” 56 is chosen, the item selection module 47 enters a mode for searching the access history to find automatically data files accessed in a default period, and for deciding retrieved files as files to be used for the multimedia presentation (step S130-S140). If “Set Period” 57 is selected, the selection module 47 enters a mode for searching the access history to find data files accessed in a user-designated period and for selecting retrieved files for the multimedia presentation (step S150-S170). If “Manual” 58 is selected, the selection module 47 enters a mode in which the user can select manually the items recorded in the access history for the multimedia presentation. “Setting” 59 is a menu option to set the default period used in “Auto” 56. 
 If the user select “Auto” 56, the item selection module 47 automatically searches the access history created by the event record module 46 (step S140 of FIG. 6), and selects the files accessed in the default period as the files used to create a multimedia presentation (step S150). When the selection is completed, the item selection module 47 stops operation (step S200), and after that the presentation-creating module 48 starts creation of a new multimedia presentation by using the selected files (step S30 in FIG. 5). 
 The default period may be set as, for example, a period from now to a certain time ago, or a period from now to the time when the image viewer 20 or the video player 21 last time. By selecting “Setting” 59 in the status of FIG. 7(b), the user can move to a user interface to change the default period. FIG. 8 is the screen view for changing the default period. The letters of “Input default time” are displayed at the center 61 of the LCD screen 2, and under of those a box 62 is provided to input a time. When the user inputs a preferred time in the box 62 using the ten-key 6, said default period is set as a period from now to the input time ago. In FIG. 8, since 1:30 is inputted in the box 62, the default period is set as a period from now to 1 hour and 30 minutes ago. In FIG. 8, the letters of “OK” are displayed in the center lower part 63 of the screen. It shows that the setting mode 59 will be terminated if the function key 3 is pressed. 
 If the user selects “Set Period” 57 from the status of FIG. 7(b), the view of the LCD screen 2 changes as shown in FIG. 9 (Step S150 of FIG. 6). FIG. 9 is a user interface to specify the period of the selection module 47 searching items to be used for the multimedia presentation. In the screen shown in FIG. 9, the Date entry box 66, the Start-time entry box 67, and the End-time entry box 68 are provided in the LCD screen 2. When the user inputs desired date and time in these boxes, the item selection module 47 searches files accessed in the period specified by those date and time, and selects the retrieved files as the files to be used for the multimedia presentation. In FIG. 9, since “01.05.2005” is inputted in the Date entry box 66, “13:00” is inputted in the Start-time entry box 67, and “14:00” is inputted in the End-time entry box 68, the specified period is 13:00-14:00 of May 1, 2005. 
 In FIG. 9, the letters “OK” are displayed in the center lower part 63 of the screen. After inputting desired date and time in the boxes 66-68, if the user presses the function key 3, the designated period is fixed and the item selection module 47 starts searching the access history in the designated period (step S160 of FIG. 6.) Then the item selection module 47 decides the retrieved files as the files to be used for the multimedia presentation (step S170), and then stops operation (step S200). After that the presentation-creating module 48 creates a new multimedia-presentation file by using the decided files (step S30 in FIG. 5). 
 When the user selects “Manual” 58 from the status of FIG. 7(b), the aspect of LCD screen 2 changes as shown in FIG. 10 (step S180 of FIG. 6). FIG. 10 illustrates a user interface of the item selection module 47 which is used by the user to choose manually the items recorded in the access history for the multimedia presentation to be created. The aspect of the access history 71, created by the event record module 46, is displayed at the center of LCD screen 2. In the access history 71 the names of the files accessed are presented in the first row 72, the types of files (i.e., picture, video, music, text . . . ) are presented in the second row 73, and accessed times are presented in the third row 74. The forth row 75 contains check boxes used for selecting presented files. In case that the whole of the access history can not be displayed in the screen at once, the user can browse the other part of the access history using the scroll bar 76. 
 The user can blackout any of columns of the access history 71 by manipulating the function key 3. FIG. 10 illustrates that the column containing a music file “Sound 1” is made blackout. If the function key 3 is pressed while a column being blackoutted, a check mark is added to the checkbox 75 of the blackoutted column and the file presented in the column is selected for the multimedia presentation to be created (step S190 of FIG. 6). In FIG. 10, it is shown that the selected files are picture files of “Manhattan” and “Statue of Liberty”, a video file of “NY—June '04”, and a music file of “NY song”. If the user presses the left key 4 after selecting all the desired files, then the item selection is completed. The item selection module stops its operation (step S200), and then the presentation-creating module 48 creates a new multimedia-presentation file by using the selected files (step S30 in FIG. 5). 
 The created multimedia presentation is a video clip and can be replayed with the video player 21. When it is replayed, each of the picture “Manhattan” and “Statue of Liberty” are presented in 1 second respectively at the beginning, then the video “NY—June '04” is replayed. The music “NY song” is used as background music of this video clip. The length of the video clip is edited to 10 second so as to suit sending by MMS. The resolution of the video clip is also adjusted to be suit for MMS. 
 It should be noted that the created multimedia presentation will also be recorded in the access history. Therefore, by applying the above software 39 to the created presentation file, it is possible to create a still further new presentation file by adding additional video clips or sounds. And preferably the imaging phone 1 is arranged to enable the user to edit the created multimedia presentation later. In this case, preferably it is arranged to enable for the user to utilize the access history so that the user can add the items recorded in the access history. 
 In this way, according to the imaging phone 1, the user can select very easily the multimedia contents to be used as the elements of the multimedia presentation based on the access history. Therefore, there is provided a way for creating the multimedia presentation easily. Also, by equipping existing portable electronic devices with the multimedia presentation creating software 39, it is possible to add above-explained features on the portable electronic devices, which can increase the usability and market values of the portable electronic devices. 
 The present invention has been described above by using a preferred embodiment. It should be understood that the embodiment of the present invention can take a lot of variations; the various modification may be possible within the scope of the present invention. The present invention may be applied not only for creating presentation files containing multimedia contents as the described embodiment, but also for creating different kind of data files. Also the present invention may be applied not only to mobile phones but also to any portable electronic devices such as PDAs, notebook computers, digital cameras, music players, portable DVD players, or voice recorders.
