ABSTRACT:
An image processing apparatus including an image processing circuit, a frequency dispersion circuit, and a timing signal generator. The image processing circuit processes an image signal, and the frequency dispersion circuit performs frequency dispersion relative to a reference clock signal by continuously modulating an oscillating frequency of the reference clock signal in a predetermined modulation cycle and to generate a frequency dispersion clock signal. The timing signal generator generates a timing signal that controls an operation of the image processing circuit using the frequency dispersion clock signal, in synchronism with the predetermined modulation cycle used for the frequency dispersion.
