Abstract
A camera incorporates a working memory (124) for storing a working image corresponding to the last captured image. The working image is displayed on a display screen (36) in a quick review mode of operation in response to a quick review signal entered by the camera operator via a camera control interface (74) to control processing circuitry (68,72) of the camera. The processing circuitry controls the display screen to keep it in an inactive state until the quick review signal is entered, and returns it to an inactive state after a predetermined time period or when the quick review signal is discontinued to conserve energy. In addition, the working image is displayed in the quick review mode regardless of whether a non-volatile memory is available in the camera or, in the case of a hybrid camera, whether a film cartridge is contained in a film chamber (98) of the camera.
