Original Abstract Submitted
An image signal processor may include a defect pixel determination unit configured to determine whether a target pixel is a defect pixel based on first comparison data that are a result of comparing pixel data of the target pixel included in a target kernel with pixel data of each of a plurality of pixels having attributes identical with attributes of the target pixel, a direction determination unit configured to determine a direction of the target kernel based on second comparison data that are a result of a comparison between pixel data of a pair of pixels that are disposed on a line in one direction and that have identical attributes, and a pixel interpolation unit configured to interpolate the pixel data of the target pixel by using the pixel data of each of a plurality of pixels that are disposed at locations corresponding to the direction of the target kernel.
