An electronic still camera employs digital processing of image signals corresponding to a still image and storage of the processed image signals in a removable static random access memory card (24). An image sensor (12) is exposed to image light and the resultant analog image information is converted to digital image signals. A control processor (20) controls the exposure section (10) and an A/D converter (16), delivering digital signals to a multi-image buffer (18) at a rate commensurate with normal operation of the camera. A digital processor (22) operates on the stored digital signals, transforming blocks of the digital signals and encoding the signals into a compressed stream of processed image signals, which are downloaded to the memory card. The digital processor (22) operates at a throughput rate different than the input rate for better image capture and optimum utilization of the camera.
