ABSTRACT:
A plurality of parameters included in a predetermined illumination equation which defines a brightness are acquired for each pixel of an image. For each of the parameters, a homogeneous region including pixels which are similar in value of the parameter is specified. In each of the specified homogeneous region, each of the parameters is converted according to details of the predetermined image conversion. The brightness of each pixel of a second image is determined using the values of the parameters obtained after the conversion.
