Video signal mixing device of infrared/visible integrated imaging apparatus
Abstract
A infrared/visible integrated imaging apparatus has a video signal mixing device for superimposing a visible video signal upon an infrared video signal. The device has a discriminating circuit (8) setting electrical discrimination between the infrared video signal having a higher level than the black level and that lower than the black level. The visible video signal simultaneously outputted with the infrared video signal having the higher level is practically cut off with a visible video signal selecting circuit (9). The partially cut off video signal is superimposed on the thermal video signal. The level of both video signals are controllable independently of each other.
