An objective of the present invention is to provide an image correction apparatus for correcting a luminance difference of each pixel resulting from a transmittance difference of an image photographed using an image sensor having a plurality of filters, which have mutually different transmittance with respect to a light from a lighting. An image correction apparatus (7) includes: a correction factor calculating unit (21) to calculate a correction factor such that a distance between a corrected value obtained by correcting, by using the correction factor, a luminance value of a first pixel on the image corresponding to a sensor element with a first filter, which has a first transmittance characteristic, in an image sensor included in an image capturing unit (11) which generates the image, and a luminance value of a second pixel on the image corresponding to a sensor element having a second filter, which has second transmittance characteristic, in the image sensor, becomes smaller than a distance between the luminance value of the first pixel and the luminance value of the second pixel; and a correcting unit (22) to generate a corrected image by correcting the luminance value of the first pixel using the correction factor. |
