<P>PROBLEM TO BE SOLVED: To provide a video signal processing apparatus equipped with a clock generation circuit generating a clock matching the clock frequency of a pixel display while cycles of the clock frequency are constant and a duty is maintained. <P>SOLUTION: The video signal processing apparatus is equipped with a 1st clock generation circuit 102 which generates a 1st clock S102 synchronized with an input signal, a 2nd clock generation circuit 103 which inputs a set value as a reference for an output frequency, adds the set value for each reference clock, extracts data according to a cumulative value, converts the data into an analog signal, reduces quantization noise, and performs multiplication to obtain a 2nd clock S103, and a clock changing circuit 108 which generates a synchronizing signal S108 by using and superposing a synchronizing signal S104 generated with the 1st clock S102, and uses the generated 2nd clock S103 according to the resolution of the pixel display to perform video signal processing. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
