description An image signal processor capable of performing image processing and a method for processing an image signal are disclosed. The image signal processor includes an image binning circuit configured to generate a second image by summing pixel values of color pixels in a first image including a pixel value of at least one phase detection pixel and the pixel values of the color pixels, a directionality strength determiner configured to calculate directionality strength information based on a target pixel disposed at a center of a target kernel within the target kernel of the second image, a pixel value comparator configured to compare the pixel value of the target pixel with pixel values of neighboring homogeneous pixels, a correction value generator configured to generate a correction value for correcting the target pixel, and a corrector configured to correct the target pixel.
