Abstract:
1. A camera signal processor characterized by comprising: motion detection means for dividing an image picked up by imaging means into a plurality of motion detection areas, and detecting the motion pattern of the image for each of the motion detection areas; extracting means for extracting, on the basis of the motion pattern of the image for each of the motion detection areas which has been detected by the motion detection means, the motion detection area where an object making abnormal motion exists; and image enlarging means for enlarging the image picked up by the imaging means, centered on the motion detection area where an object making abnormal motion exists which has been extracted by the extracting means and displaying the enlarged image on a display device, said image enlarging means comprising group forming means for grouping, out of the motion detection areas where an object making abnormal motion exists which have been extracted by the extracting means, the areas where an object making abnormal motion exists such that the areas connected to each other form group: center-of-gravity detecting means for extracting, out of groups formed by the group forming means, the group having the largest area, and finding the center of gravity of the extracted group; and scaling-up means for scaling up the image picked up by the imaging means, centered on the center of gravity found by center-of-gravity detecting means, and displaying the scaled-up image on a display device.
