<p><P>PROBLEM TO BE SOLVED: To provide a technique whereby a mixing point of noise and its timing, and more preferably its generation source can be easily grasped by grasping the mixing point of the noise mixed in a main scan synchronizing signal and its timing. <P>SOLUTION: An image signal processor comprises a reference pulse signal receiving part which receives a reference pulse signal of a preliminarily set period from the outside, an image signal receiving part which receives both a synchronizing signal that can be delayed to the reference pulse signal and an image signal synchronized with the synchronizing signal from an external unit, an image signal processing part which processes the received picture signal, and a delayed time storing part which stores a delayed time of the synchronizing signal when the synchronizing signal is not in a first range preliminarily set to the reference pulse signal. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
