Image processing apparatus, image processing method, and image processing program

摘要

An image processing apparatus includes an acquisition unit configured to acquire an input image represented with a plurality of color components including at least first and second color components, a correlation calculation unit configured to calculate a grayscale direction correlation indicating whether grayscale directions of the first color component and the second color component are identical or opposite for a region of interest in the input image, a high frequency component calculation unit configured to calculate a high frequency component of the first color component for the region of interest, and a correction unit configured to correct the second color component for the region of interest using the high frequency component of the first color component calculated by the high frequency component calculation unit in accordance with a method depending on the grayscale direction correlation calculated by the correlation calculation unit.
