Abstract
A detection signal of an image pickup device is inputted to a gate circuit to open the gate circuit by a gate signal from a drive-signal generating circuit during a period of time of a phase regulating signal section of a drive signal, to thereby output the detection signal during the period of time, to a reference reset generating circuit. The reference reset generating circuit generates a reference reset signal on the basis of the detection signal during a period of time of the inputted phase regulation signal section. The reference reset signal and a basic clock signal are inputted to a timing-pulse generating circuit for generating various kinds of timing pulses which are used in an image-pickup-signal processing circuit for processing in signal the image pickup signal.
