Abstract
A digital still camera comprises a full image processor and a rough image processor. The full image processor generates compressed full image data as primary image data, while the rough image processor generates non-compressed rough image data as secondary image data whose data volume has been reduced by limiting pixels thereof. In a reproduction mode, rough image data is read from a memory and subjected to display processing. A rough image is generated based on non-compressed rough image data with a short reproduction waiting time and displayed on an image display device. Thereafter, corresponding full image data is processed for display so that a relevant full image replaces the displayed rough image data, to be finally displayed.
