<p><P>PROBLEM TO BE SOLVED: To provide a signal processor, semiconductor device and graphic display device, capable of achieving power saving while restraining enlargement of a circuit. <P>SOLUTION: A video signal with a synchronous signal is input at predetermined intervals. A clamp section 24 at a pre-stage of an AFE 20 that processes the input video signal detects a synchronous signal. When the synchronous signal is detected, a signal level of the video signal is adjusted, and a control section 25 controls so that the power consumption of the AFE 20 is restrained based on a detection result from the clamp section 24. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
