发明名称 Electronic photography system with still and motion picture modes
摘要 An electronic still/motion picture photography system includes an optical-electronic transducer for producing electrical signals responsive to an optical image, a light information control member such as a diaphragm for controlling the state of the light information incident on the transducer, a discriminating circuit for determining the state of the light information as it is controlled by the light information control member, a drive source responsive to the output of the discriminating circuit for driving the light information control member, a recorder for recording the output of the transducer, an indicating switch for indicating the amount of output representing the exposed image to be recorded by the recorder, and a computer circuit responsive to the output of the indicating switch for changing the driving characteristics of the drive source.
