Abstract
A lower frequency clock signal is supplied to a CCD line sensor. The step-like test signal detected by a scanning circuit is converted by means of a defining circuit and supplied to an evaluation circuit. The position of a light bar on a sensor is accurately determined by comparison with a higher frequency clock signal.
