IMAGE PROCESSOR, IMAGING APPARATUS, IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To effectively and efficiently remove noise by smoothing.

SOLUTION: An image processor includes: an image input unit for inputting images in which a first pixel group and a second pixel group indicating the intensities of color components different from each other are arrayed in coexistence and the second pixel group is arrayed at a discrete position; a color estimation unit 301 for estimating first color component data at each position of the discrete second pixel group on the basis of the first color component data which is color component data that each first pixel group has; a calculation unit 302 for calculating color difference data at each position of the discrete second pixel group on the basis of the first color component data and the second color component data; a smoothing unit 303 for executing spatial smoothing processing to a discrete color difference image constituted of the color difference data calculated at the position of the discrete second pixel group; and a color difference estimation unit 304 for estimating the color difference data at each position of the pixel group other than the second pixel group on the image on the basis of the discrete color difference image after the smoothing processing.
