Abstract
A color image display control apparatus for receiving a composite color picture signal and processing color image data included in the signal. A color picture signal in an analog form included in the composite color picture signal is converted to a digital form by sampling the analog signal at each cycle of a sampling clock, in and analog to digital converter. The digital image data is processed in a digital image processing circuit. Processed digital data is converted to analog data in a digital to analog converter. Information regarding a phase difference between the sampling clock and each horizontal synchronizing signal in the composite color picture signal is obtained. According to the information, a digital image data in a line corresponding to each horizontal synchronizing signal, which was sampled by the sampling clock, is modified so that the influence of the above phase difference on a displayed image of the processed image data is corrected.
