Abstract:
A digital electronic still-video camera for obtaining image data representing the image of a subject by picking up the image of the subject using image sensing means, processing the obtained image data and recording the processed image data on a recording medium, comprising:a plurality of memory modules each of which includes: an image memory to and from which data can be written and read for processing, the image memory being different from said recording medium, and an image memory control circuit responsive to an applied standby/active control signal for placing said image memory in a standby or active state and controlling said image memory in such a manner that when said image memory has been placed in the active state, image data obtained from the image sensing means is written to said image memory or image data that has been written to said image memory is read out of said image memory; and a memory module control circuit for applying the standby/active control signal to said image memory control circuits included in said plurality of memory modules, wherein, during an image record operation in which the image data obtained by said image sensing means is compressed and stored on the recording medium in compressed form, the obtained image data is compressed using at least one of the plurality of memory modules including the image memory placed in the active state, and the image data that has been compressed using at least one of the plurality of memory modules is recorded on said recording medium.
