Furthermore, the still images captured in this case are combined with a full image consisting of all pixels in one frame to form an index image in which pixels are extracted at a predetermined ratio, and these still images are used in the search. A disc libter containing an arbitrary classification code etc. is added and formed.

Are these 2WI still images and disc libters stored in memory in a predetermined format? written to if (IA). The format is such that the disc libter, full picture, and index picture are each written in independent areas, and the addresses of the corresponding full picture and index picture are provided within the disc libta.

That is, when the search [22] is started, the disk salt to be searched is first displayed on the color display (202) (step A), and it is asked whether or not to display the directory in this state (step B). When the user selects YES using the keyboard (203) or the like, the directory is displayed on the color display (202) (Step C), and in this state the user makes a selection using the keyboard (203) or the like (Step D). .

Furthermore, a question is asked as to whether or not to display a title in this state (step E). Then the user uses the keyboard (203)
etc., if you select Yes, the color display (202
) is displayed (step F), and in this state, the user makes a selection using the keyboard (203), etc. (step G), and when a title is selected, the title is included in the selected title. Disc libters of all still images are continuously output from the drive device (103) [11] (
In step H), the search is terminated. It is also possible to select multiple titles.

On the other hand, if No is selected in step B, the disc libter of all still images on the disc will be transferred to the drive device (
103) (step summer), and if No is selected in step E, disc libters of all still images included in the directory selected in step D are continuously output from the drive device (103). [11] is carried out (step J).

The disc libters that are successively produced in this way [11] are analyzed [12], and the addresses of the index picture and full picture are stored [13], and the index picture is stored from the drive device (103) according to the analyzed addresses. The index image is then read [14] and transferred to the memory device (IA). This memory device (
The index image transferred to the IA) is further transferred to the interface circuit (16). Therefore, classified and saved still images can be retrieved from any hierarchy of disk, directory, or title.

Further, the interface circuit (16) is provided with an image memory (16M) corresponding to, for example, all pixels of the color display (202), and the CPU (201)
For example, a background image as shown in FIG. 5 is formed by the signals supplied from the. Then, for each diagonally lined range ■~@ in the upper half of this background image, address control is performed.
(15), the above-mentioned index pictures are sequentially written and displayed. By writing all the searched index pictures once into the memory device (IA), for example, when there are 13 or more index pictures, You can access other displayed pages quickly.

On the other hand, the lower half of the background image is also marked with a diagonal line.
