Abstract: The present disclosure provides a color compensation circuit, a display apparatus, and a color compensation method, wherein the color compensation circuit comprises an acquisition unit for acquiring, from a video signal, gray image of a frame to be displayed and chrominance image of any color; wherein a chrominance value in the video signal, corresponding to at least a portion of pixels within the chrominance image, is absent; a processing unit for smoothly processing the chrominance value in the chrominance image according to the change trend of gray value in the gray image to obtain a chrominance image with color compensated. The present disclosure can solve the problem that compression and decompression of a video signal during transmission will significantly decrease the frame display effect, and thereby helping improve the frame display effect in a transmission scenario with the loss of chrominance value of the video signal.
