LIGHT SOURCE ESTIMATION DEVICE, IMAGE PROCESSING SYSTEM, AND LIGHT SOURCE ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce a sense of incongruity of a displayed CG image.SOLUTION: A light source estimation device comprises: an imaging unit that captures an image; a storage unit that previously stores shape information indicating a shape of a reference object as a reference of light source estimation; and an estimation unit that estimates a light source environment of the image captured by the imaging unit on the basis of an image of the reference object included in the image captured by the imaging unit and the shape information stored in the storage unit.
