9. The method of claim 4 , wherein the method further comprises: capturing the images focused through a lens by a signal processor.
4. A data recording and reproducing method comprising: processing captured images to generate images data, and generating an image file comprising the image data; recognizing first speech by speech recognition unit, which is related to the image data, and converting the first speech into first text data by the speech recognition unit; by a controller using a processor, generating first metadata using the first text data and adding the generated first metadata to the image file, wherein the controller generates a folder having a name based on the first text data and wherein the controller stores the image file in the folder having the name based on the first text data; and storing the generated image file in a storage unit; displaying an image from the captured images represented by the image data included in the image file or displaying the first metadata along with the image, wherein the first metadata comprises a description tag which is generated using the first text data and a keyword tag which is generated by extracting keywords from the first text data; wherein, when newly input second speech is converted into second text data by said speech recognition unit while the images stored in the image file are displayed, generating second metadata from the second text data and comparing if the second metadata is different with the first metadata in the image file by the controller, and if the second metadata is different from the first metadata in the image file, the controller adds the second metadata to the first metadata in the image file.
