ABSTRACT:
In a color imaging apparatus, an optical image is focused on a photoelectrical conversion target of a color image pickup tube through a color stripe filter having a plurality of successively arranged recurrent groups of different color stripes and converted to an electrostatic image which is scanned in rectangular raster form by an electron beam to generate a luminance signal and a color-multiplexed video signal. The leading and trailing edges of the luminance signal are detected by an edge detector to generate a control signal having first and second polarities in response to the detection of the leading and trailing edges, respectively. The color multiplexed signal is phase-controlled with respect to the leading and trailing edges of the luminance signal in accordance with the control signal by a variable delay line or by a pair of beam deflection plates.
