Abstract
A single tube color video camera apparatus having a camera tube including a color separation stripe filter and producing an output signal containing a color multiplex carrier signal, utilizes an envelope detector for directly detecting the camera tube output signal to produce an envelope detection signal which varies in accordance with an electrical charge pattern of the tube target. Phase control of the color multiplex carrier signal extracted from the camera tube output signal is executed based upon the envelope detection signal, to thereby correct for color signal phase deviations caused by variations in light intensity of scenes viewed by the camera.
