Abstract
The present invention generally concerns an automatic exposure camera and, more particularly, one incorporating a so-called AE locking device or circuit. In such a camera, the proper or optimum exposure values are automatically determined by electronic circuitry and the exposure operation is controlled in accordance with that determination. In addition, the control circuitry by which the exposure operation is accomplished is 'locked' during the exposure so as to hold--as in a memory device--the proper exposure values determined immediately prior to the exposure operation by automatically actuating the AE locking device. The present invention provides for connection between the AE locking circuit and the warning device so as to inhibit the output of the warning device--and prevent an erroneous indication by the indicating unit--on actuation of the AE locking circuit. In the absence of this particularly advantageous feature, the 'low light' indicator would likely be actuated each time an exposure was carried out as the return mirror in the camera was upwardly pivotted. Other erroneous indications would similarly occur when the AE locking circuit was selectively used to retain an exposure determination for a subsequent photographing operation.
