ABSTRACT:
A circuit and method for processing an image to correct the pixel value of a sub-pixel included in color data to reduce color differences. The image processing circuit includes a plurality of defect determination circuits respectively corresponding to a plurality of sub-pixels (colors). Each defect determination circuit determines whether or not the corresponding sub-pixel, or first sub-pixel, includes a defect and generates a determination signal. The defect determination circuits provide each of a plurality of correction circuits respectively corresponding to a plurality of sub-pixels (colors) with the determination signals. Each correction circuit generates a corrected value for the corresponding first sub-pixel when at least one of the determination signal is indicative of a defect.
