Abstract

PURPOSE: To detect the colored image at an object position to be discriminated in a real time precisely by picturing the object to be photographed having a spot and the object to be photographed having no spot by two sets of color TV cameras, comparing the signal thereof by the subtractor.
CONSTITUTION: By the combination of the shutting cycles of the shutters 22W24, the color TV camera 2 intermittently photographs only the object 36 to be pictured having a spot 37 due to the projector 34 and the color TV camera 3 photographs only the object 36 having no spot 37. The analog subtractors 4, 5, 6 compares the same colored signals obtained from the cameras 2, 3 in order to extract the color signal only displaying the spot 37, obtains the difference between the signals trasmits the color difference signals 44, 45, 46 to the window type comparators 7, 8, 9. The scanning signal obtained from the cameras 2, 3 and the signal pulse of the internal oscillator are counted by the pulse counters 11, 12 to determine the horizontal and vertical coordinates. The latch memory 13, 14 latches the counted content 60, 61 and coordinate 62, 63 indicating the color image position are transmitted.
