1. An image processing apparatus, comprising:
a central processing unit (CPU) configured to:
estimate a first light source region in an input image;
generate input light source region information that indicates the estimated first light source region in the input image;
generate viewpoint conversion light source region information that indicates a second light source region in a viewpoint-converted image;
calculate, based on the input light source region information and the viewpoint conversion light source region information, information that indicates a change between the first light source region and the second light source region; and
change representation of light in the viewpoint-converted image based on the information that indicates the change between the first light source region and the second light source region.
