Abstract
A signal processing apparatus includes a first clock generation circuit for generating a first clock signal having a constant frequency, a detection circuit for detecting a phase change in an input video signal, a second clock generation circuit for generating a second clock signal having a frequency different from the frequency of the first clock signal by selectively using the first clock signal and an output from the detection circuit, and a signal processing circuit for processing the video signal using the second clock signal.
