IPC: H04N5/781
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To provide an electronic camera that can properly photograph an object while suppressing consumption of a battery to the utmost. SOLUTION: In the case that the electronic camera provided with an optical finder is in a photographing state, since a photographer frequently views an object via the optical finder, it seldom requires for the photographer to monitor an image of the object by using a liquid crystal display monitor.

Thus, when the electronic camera is in the photographing state, the MPU 5 interrupts power supply to the liquid crystal display monitor 9 to save power of the electronic camera.
