ELECTRONIC CAMERA WITH QUICK REVIEW OF LAST CAPTURED IMAGE
First Claim
1. A camera comprising:
- digital imaging means for generating a digital image representative of a subject scene;
fixed working memory means for receiving and storing the digital image generated by the digital imaging means as a working image;
a non-volatile memory for storing digital images;
a display screen; and
control processing means for controlling the operation of the digital imaging means, the fixed working memory means and the display screen;
wherein the control processing means generates a digital mode image from the working image stored in the working memory and transfers of the digital mode image to the non-volatile memory while retaining the working image in the working memory;
wherein the control processing means selectively generates a display image from a digital mode image stored in the non-volatile memory and transfers the display image to the display screen for display; and
wherein the control processing means selectively generates a quick review image from the working image stored in the working memory and supplies the quick review image to the display screen for display without requiring availability of the non-volatile memory.

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.
