Abstract
Image data of a digital signal is inputted to a digital signal processor. A CPU reads out color correction coefficients from a ROM. Weights are added to the color correction coefficients based on information regarding transfer efficiency of a CCD image sensor such that the coefficients in a horizontal direction are set larger than those in a vertical direction. Further, an interpolation processor calculates horizontal and vertical components of R, G, and B colors of each pixel through color interpolation processing based on image data of each pixel and its peripheral pixels. A linear matrix circuit is controlled by the CPU and subjects the horizontal and vertical components to linear matrix operation using the color correction coefficients, thus subjecting each pixel data to color correction processing.
