ABSTRACT:
An addition unit adds information for managing a plurality of image-data files to directory information packets. A managing unit utilizes the added information for managing the plurality of image-data files. A retrieving unit retrieves, in accordance with an input retrieving information, a desired image-data file from among the plurality of image-data files recorded on a recording medium. An image-data input and output interfacing unit interfaces for input and output of image-data files. A recording-medium interfacing unit interfaces for information input and output by means of the recording medium. An output video-signal producing unit produces a video signal for output, the producing being effected by converting the retrieved image-data file into a corresponding analog video signal and using the analog video signal as the video signal for output. A signal combining unit combines the video signal for output, the combining being executed with a retrieval video signal, the video signal for output having been output from the output video-signal producing unit, and the retrieval video signal having been obtained by converting the input retrieving information into a corresponding analog video signal then used as the retrieval video signal. A microcomputer carries out the above functions.
