PURPOSE:To prevent the failure of photographing by controlling a focus frame generating circuit outputting a focus frame signal for indicating a certain area in a screen decided by a gate circuit according to the discriminated result of the attaching and detaching state of a lens unit to a main body unit of a camera. CONSTITUTION:The attaching and detaching state of an lens unit LU to a main body unit CU a camera is discriminated According to the discriminated result, a focus frame generating circuit 41 outputting the focus frame signal for indicating the certain area in a screen decided by a gate circuit 42 is controlled. Thus, it is possible to know the attaching and detaching state of the lens unit LU easily, to prevent the failure of the photographing, and not to generate futile worry and anxiety to a photographer. |
