Abstract
A color image processing apparatus has a CCD shift register for reading a color image in accordance with reference clock pulses, a pre-sample-hold circuit for performing color separation of serial color signals and producing parallel color signal in accordance with sample clock pulses, post-sample-hold circuits, and a matrix circuit for correcting the color signals. The CCD shift register, the pre-sample-hold circuit and the post-sample-hold circuits can be integrated as a line sensor. Serial color signals can be processed at high speed and at low cost.
