| Abstract: |
A digital electronic still-video camera is capable of performing rapid-sequence photography at high speeds. When a rapid-sequence photographic mode has been set, each of a plurality of frames of image data obtained by such photography is compressed. Image data which forms a single multiple-frame picture is constructed by a set of image data composed of the compressed plurality of frames. Thinning out is performed in order to compress the image data. The image data is successively stored, while being thinned out, at corresponding addresses of an image memory in such a manner that a multiple-frame picture is constructed in the image memory. After photography in the rapid-sequence mode ends, the image data in the image memory is subjected to data compression and then recorded on a memory card.

What is claimed is:
1. A digital electronic still-video camera having a rapid sequence photographic mode in which image data representing a plurality of successively picked-up frames is reduced for storage in a plurality of areas in an image memory, comprising:
- an image pick-up device for outputting image data, which represents the image of a subject, each time a picture is taken in the rapid-sequence photographic mode;
- said image memory for storing one frame of image data;
- a frame-number storage device for storing a rapid-sequence frame-number;
- a data reducing device for reducing the amount of one frame of image data which is output by said image pick-up device, at a reduction rate determined in accordance with the rapid-sequence frame-number stored in said frame-number storage device, and for outputting the reduced image data;
- a frame-number counting device for counting a number of frames successively picked-up in rapid-sequence, and storing the counted number;
- a relative address generating device for generating and outputting a relative address of an area of said image memory; and
- an absolute address generating device for determining an offset address based upon the rapid-sequence frame-number stored in said frame-number storage device and the counted number stored in said frame-number counting device, and for generating and outputting an absolute address using the determined offset address and the relative address output from said relative-address generating device, the absolute address designating a location in said image memory where the reduced image data output from said data reducing device is stored,
- whereby reduced image data is stored in the plurality of areas of said image memory in such an arrangement that a multiple-frame picture is formed in said image memory.
