ABSTRACT:
An electronic camera includes: an image sensor for converting an optical image relating to a photographic object into electric signals; a processor for compress-processing image data corresponding to the electric signals at a predetermined compression ratio for each of a plurality of blocks to obtain compressed image data. The processor compares a data amount of the compressed image data with a predetermined amount of data, and compress-processes again the image data at a compression ratio greater than the predetermined compression ratio only when the data amount of the compressed image data exceeds the predetermined amount of data. The electronic camera further includes a recorder for storing the compressed image data compress-processed by the processor in a memory medium.
