Pixel defect detecting/correcting device and pixel defect detecting/correcting method

摘要

A pixel defect detecting and correcting apparatus and method for detecting and correcting defects where the number of correctable defect pixels is not restricted to the capacity of a memory. The apparatus includes a color difference and luminance calculating block which calculates the absolute values of the color differences of adjacent pixels and a defect judgment target pixel, and color difference and luminance data. The apparatus also includes a maximum and minimum data values detecting block; a color difference interpolated value calculating block and a luminance interpolated value calculating block which obtain the color difference interpolated values and luminance interpolated values of the defect judgment target pixel.
