ことを特徴とするカラー映像信号撮像装置。 In a color video signal imaging device that outputs a color video signal by photoelectrically converting light from an object to be imaged and transmitting a luminance signal and a carrier color signal obtained through predetermined processing together with a composite synchronization signal and a color burst signal. , the color burst signal is 18
a phase shift circuit that shifts the phase by an angle of 0° and its vicinity; an inversion circuit that inverts the polarity of the luminance signal other than the composite synchronization signal with respect to the original polarity; and the color burst signal to be transmitted and the phase shift circuit. a first changeover switch configured to transmit either the color burst signal phase-shifted by the circuit, the luminance signal excluding the composite synchronization signal to be transmitted, or the output polarity-inverted luminance signal of the inversion circuit; and a second changeover switch for switching so that either one of the color burst signal to be transmitted and the luminance signal other than the composite synchronization signal is transmitted, and the phase shift circuit Either or both of the phase-shifted color burst signal and the output polarity-inverted luminance signal of the inversion circuit can be arbitrarily switched to be transmitted and output together with the carrier color signal and the composite synchronization signal. Characteristic color video signal imaging device.
