PURPOSE:To realize a very natural retrieval such as a picture is retrieved by a picture, by using a plurality of synthesized pictures made by shrinking original pictures for retrieval. CONSTITUTION:A picture inputted from a picture input device 11 is stored in a picture memory 12 and displayed on a monitor 15. In inputting an instruction registrating this picture to a file from an operating console 17, a CPU19 writes a picture data in the memory 12 to a magnetic disc device. The picture data in the memory 2 is shrinked with a shrinking device 16a and written in a device 14. The correspondence between the registrated picture and the shrinked picture is 1:1, and the addresses of the both on a disc are written in the address area on the disc. In inputting an instruction of shrinked index from the console 17, the CPU19 reads out the shrinked picture in the order of addresses written in the address area on the disc from the device 14, a plurality of shrinked pictures are synthesized at a synthesizer 16b, the shrinked picture index is written in the memory 12 and displayed on the monitor 15. |
