Abstract

An auxiliary focusing circuit for an automatic focusing solid state array camera includes a control circuit and a drive circuit. The camera includes a switch which is actuated when the lens travels a selected distance without being focused. The control circuit responds to the switch and actuates the drive circuit. The switch also reverses the direction of travel of the lens. The drive circuit rotates an optical scanning member and the camera can be focused while the lens travels in the opposite direction.
