Abstract:
1. An image reading apparatus comprising: a light source that generates light by synthesizing light from different illuminants, and that irradiates an irradiated object with the light thus generated; a reading unit that reads light irradiated by the light source and reflected by the irradiated object, and that generates image information on the irradiated object; a correction amount setting unit that acquires from the reading unit the image information generated by using, as the irradiated object, a color sample formed in a color of light emitted by any one of the illuminants generating the light of the light source, and that sets, according to the image information thus acquired, a correction amount to correct the image information on the irradiated object generated by the reading unit; and a correction unit that corrects the image information on the irradiated object generated by the reading unit, by using the correction amount set by the correction amount setting unit, wherein the correction amount setting unit sets the correction amount to correct the image information on the irradiated object, in response to determining that color coordinates of the image information on the color sample are located outside of a predetermined color region in a color space including the color coordinates.
