Apparatus and method for compensating a color carrier of an image signal |
摘要 |
An apparatus to compensate a color carrier in an image processing system to convert an input analog image signal into a digital image signal includes a detector, a phase-locked loop unit, a difference detector, and a color signal processor. The detector detects a frequency of the color carrier in a color signal of the digital image signal. The phase-locked loop unit generates a subcarrier frequency by performing a phase-locked loop operation on a system clock signal applied to the image processing system. The difference detector detects a difference between the frequency of the color carrier and the subcarrier frequency. The color signal processor compensates for a phase deviation of the color carrier of the color signal using the subcarrier frequency generated by the phase-locked loop unit.
