Abstract
PURPOSE: To provide a stable and highly reliable input picture signal by providing an arithmetic unit which finds a differential signal between a picture signal one screen before and a picture signal taken at present and converts it into an absolute value, and a picture signal normalizing device which normalizes the output signal of the arithmetic value and outputs it to an image processing device. CONSTITUTION: A visual device separates and outputs a vertical synchronous signal from a picture signal 3 outputted by a TV camera 2 by an inter-picture differential arithmetic device 5, finds a differential signal between the picture signal from which the vertical synchronous signal 9 is separated, and a picture signal one screen before which is obtained similarly, and converts the differential signal into an absolute value. The output signal 10 of the arithmetic device 5 is normalized by a picture signal normalizing device 7 and outputted to an image processing device. On the other hand, the vertical synchronous signal 9 is inputted from the arithmetic device 5 to a lighting controller 6 and the lighting level of a lighting system 4 is alternatively changed into two levels according to the vertical synchronous signal 9. The superior picture signal 12 of a fixed amplitude which exerts no affect on background light, namely, a disturbance light can be thus inputted.
