ABSTRACT:
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. An image sensor is exposed to image light and the resultant analog image information is converted to digital image signals. A control processor controls the exposure section and the A/D converter, delivering digital signals to a multi-image buffer at a rate commensurate with normal operation of the camera. A digital processor 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 operates at a throughput rate different than the input rate for better image capture and optimum utilization of the camera.
