Abstract
An image processing device includes: a first smoothing unit calculating, regarding multiple positions along a first direction in a neighbor region of a predetermined pixel of interest in an input image, a first-stage smoothing value wherein pixel values have been smoothed along a second direction differing from the first, for a first channel; a second smoothing unit calculating, regarding multiple positions along the first direction in the neighbor region, a first-stage smoothing value wherein pixel values have been smoothed along the second direction, for a second channel; an intensity estimating unit estimating the intensity of the first-stage smoothing value of the second channel, based on the first-stage smoothing values of the first and second channels; and a third smoothing unit calculating a second-stage smoothing value for the second channel, the first-stage smoothing value of the second channel intensity-estimated by the intensity estimating unit having been smoothed along the first direction.
