METHOD AND APPARATUS FOR OBTAINING LIGHTING INFORMATION AND MATERIAL INFORMATION IN IMAGE MODELING SYSTEM

An apparatus and method for obtaining lighting information and material information in an image modeling system are provided. A material constant of a same material region and lighting information of the same material region may be extracted by applying color channel pixel values, depth values, and viewpoint information to a linear system in which a pixel value is defined by a material constant and a combination of a geometry component with a lighting component.
