Abstract
In a camera section, a luminance signal and the predetermined hue gate signal are modulated by a modulator in a quadrature modulation manner and the modulated signal is transmitted to a camera control unit via a cable. The modulated signal is separated by a branching filter in the unit and demodulated by a demodulator to generate the luminance signal and the detection signal. A signal to which the luminance signal and the detection signal are added, is used as a monitor video signal and a white image is displayed on a monitor screen within a range for the detection signal. Thus, the range detection signal can be observed with the monitor screen. Since the unit uses the added signal as the monitor video signal and the luminance signal for another purpose, the range of the detection signal can be observed by the monitor screen while using the luminance signal for another purpose.
