Abstract: An image correction apparatus generates, for each pixel of a reduced image generated from an input image, a first smoothed image using each reference pixel in a filter area in which a difference obtained by subtracting a luminance value of the pixel from a luminance value of the reference pixel becomes less than a predetermined value, generates a second smoothed image using each reference pixel in the filter area in which the difference obtained by subtracting the luminance value of the reference pixel from the luminance value of the pixel becomes less than the predetermined value, and generates a smoothed image for correction of the input image based on the first smoothed image and the second smoothed image.

Abstract: A memory unit stores as conversion information which is derived based on a correction coefficient which provides, in a predetermined allowable range from a minimum value, a sum of a norm of a difference between a color difference of a correction target color and a target color which is a target of correction of the correction target color and a correction color obtained by correcting the correction target color using the correction coefficient, and a norm of the correction coefficient to which a predetermined weight coefficient is applied. A color correcting unit converts a color of each pixel of an image captured by an image capturing unit based on the conversion information.
