1. An image processing device comprising:
a target pixel set determiner configured to determine a target pixel set, among a plurality of Phase Detection Auto Focus (PDAF) pixel sets, based on average values and variance values of pixel values output from a plurality of pixels corresponding to a kernel set based on each of the plurality of PDAF pixel sets, wherein the average values and the variance values respectively correspond to colors of color filters included in the plurality of pixels; and
a pixel value corrector configured to convert pixel values of the target pixel set into first pixel values corresponding to a predetermined color and configured to correct the first pixel values to second pixel values corresponding to an arrangement pattern of the plurality of pixels based on pixel values of a plurality of adjacent pixels adjacent to the target pixel set.
