Abstract
A conversion matrix determining method for determining a conversion matrix to be used in color conversion processing executed on a photographic image, includes: obtaining image data of an image captured under a given condition and a colorimetric value measured under a condition identical to the given condition from a subject of the image data; and determining a conversion matrix to be used to execute color conversion on an image signal in a nonlinear color space where a luminance value changes nonlinearly, based upon the image data and the colorimetric value having been obtained.
