Image processing apparatus, image processing method, and program therefor

摘要

An image processing apparatus processes an input image while also considering the luminous intensity information thereof, and thereby generates an output image wherein the apparent object surface roughness has been enhanced with respect to the input image. The image processing apparatus includes a luminous intensity information separator that separates the input image information into global luminous intensity information and local luminous intensity information, a shadow component generator that generates a shadow component of the image on the basis of the local luminous intensity information, and an image compositor that generates an output image by adding shadow image information to the input image information, with the shadow image information being generated from the shadow component and from a value based on the input image information.
