ABSTRACT:
A light source presuming apparatus includes: a candidate light source color obtaining unit which obtains candidate light source colors; a guide light source color holding unit which holds guide light source colors for guiding obtainment of parameters of a color adaptation model showing color adaptation of the sight sense from the candidate light source colors to a reference light source color; a guide parameter obtaining unit which obtains such parameters so as to be guided to the guide light source colors; an error converging unit which obtains light source colors, as correction candidate light source colors, having the relation showing the color adaptation of the sight sense with the reference light source color by using the color adaptation model shown by guide parameters, substitutes the correction candidate light source colors for the candidate light source colors, and converges errors included in the candidate light source colors; and a light source color presuming unit which presumes the correction candidate light source color of the minimum errors as a light source color of the image data.
