ABSTRACT:
A camera equipped with detectors for detecting: a) the photographer is holding the camera grip, and b) the photographer is looking into the viewfinder of the camera. When both are detected, which can be assumed that he is taking a photograph in the near future, a predetermined operation of the camera (e.g., an automatic program zooming, an autofocusing, a photometering, etc.) is started. The detectors can also be used for ending a predetermined operation of the camera. When the photographer no longer holds the grip or when he no longer looks into the viewfinder, it is assumed that he is not going to take a photograph and hence it is better not to continue some proper operation for conserving the battery power. For confirming the judgment, it is preferred to check the detection twice in any case.
