Image processing circuit and image processing method for correcting color pixel defects

摘要

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 (10) includes a plurality of defect determination circuits (11R, 11G, 11B) respectively corresponding to a plurality of sub-pixels (colors). Each defect determination circuit (11R, 11G, 11B) determines whether or not the corresponding sub-pixel, or first sub-pixel (R11, G11, B11), includes a defect and generates a determination signal (SR, SG, SB). The defect determination circuits (11R, 11G, 11B) provide each of a plurality of correction circuits (12R, 12G, 12B) 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.
