PROBLEM TO BE SOLVED: To provide an image processor in which mask processing for privacy protection does not damage a supervisory function in a video supervisory system using a supervisory camera. SOLUTION: A motion area is detected from a video signal of the supervisory camera, and a relative position relation between the motion area and a mask area for privacy protection is judged. When no motion area exists or a motion area is located outside the mask area, or when the entire motion area is located within the mask area, the mask area is masked as it is, and when a portion of the motion area is located within the mask area, masking is performed so as to exclude the portion of the area from the mask area to thereby make the entire image of the motion area displayable. This can provide an image processor that does not damage the supervisory function. COPYRIGHT: (C)2007,JPO&INPIT
