Abstract
A difference in sampling data of continuous two pixels in a digital image signal is detected. A CPU monitors the value of an output signal and determines a control value of a control signal so as to make the difference greatest. In a sampling clock generation section, a sampling clock that is synchronous to a dot clock by a synchronous signal and the control signal is generated. When the difference becomes greatest, it is possible to sample an image signal level that is less susceptible to influences from rounding, and consequently to adjust the phase of the sampling clock without an input signal having a specific pattern.
