Abstract
First image data obtained by capturing an image of a subject under a first light condition, and second image data obtained by capturing an image of the subject under a second light condition different from the first light condition are input. The sampling positions of colors used to generate correction parameters are acquired. First color signal values are sampled from the sampling positions in the first image data, and second color signal values are sampled from the sampling positions in the second image data. Correction parameters used to correct the first image data which depends on the first light condition into image data which depends on the second light condition are generated based on the first and second color signal values.
