Abstract
A camera controller is provided wherein a variance in CMOS analog circuits can be corrected and degradation in characteristics prevented without incurring an increase in cost. In a camera controller, a microcomputer, a measuring circuit for a camera and a characteristic alteration circuit are fabricated on a single semiconductor chip. The microcomputer causes the characteristic alteration circuit to alter characteristics of the measuring circuit. The microcomputer activates the measuring circuit and controls the camera on the basis of a measurement output from the measuring circuit.
