Abstract
An image processing device according to the present invention includes: a color space conversion unit that calculates brightness signals and color difference signals from RGB signals of two images of a single subject acquired under different image acquisition conditions; a color difference determination unit that determines whether or not the absolute value of the difference between the color difference signals of the two images calculated by the color space conversion unit is smaller than a predetermined threshold value; and a color averaging unit that, if the color difference determination unit determines that the absolute value of the difference between the color difference signals of the two images is smaller than the threshold value, averages the color difference signals of the two images and calculates average color difference signals.
