Abstract
A method for performing bad pixel compensation includes: with regard to each direction of a plurality of directions, summing up absolute values of differences between a plurality of sets of first pixel values around a target pixel of an image to generate a first detection value, and with regard to each direction of at least a portion of the directions, summing up absolute values of differences between a plurality of sets of second pixel values around the target pixel to generate a second detection value, where each set of the sets of first pixel values and the sets of second pixel values includes two pixel values corresponding to a difference; and with regard to a specific direction of the directions, selectively performing bad pixel compensation on the target pixel according to the first detection value and the second detection value. An associated apparatus is also provided.
