Patent abstract
At the time of manual adjustment, a motor driving signal corresponding to a user's key operation is fed to a focusing motor from a microcomputer through a switch. At the time of automatic adjustment, the switch selects a motor driving signal from a sensor and feeds the selected motor driving signal to the focusing motor. The sensor contains a dedicated microcomputer. The dedicated microcomputer samples an image pick-up signal of a CCD line sensor in the sensor to generate contrast data, and automatically drives the focusing motor, to automatically make focusing adjustment.
