Abstract

PURPOSE:To detect abnormality with high precision by reading out and comparing image data stored in first and second image storage means and recognizing the abnormality to output a detection signal in case of discrepancy. CONSTITUTION:An optical image is inputted to a TV camera 1 as the image pickup means, and an image signal is outputted from the camera 1 and passes a camera controller 2 and is stored in first and second image storage memories 3A and 3B with a frame as the unit. An image switching write circuit 4 is interposed between the image pickup means 1 and first and second image storage memories 3A and 3B and writes the image signal from the image pickup means 1 in first and second image storage memories 3A and 3B alternately. A comparison processing circuit 5 reads out two image data stored in first and second image storage memories 3A and 3B respectively and compares both images with each other and when they do not coincide with each other, the circuit 5 recognizes the abnormality to output the detection signal. In this case, the resolution is high and the abnormality is detected with high precision since images to be compared have frames as units.
