Claim:
1. A lighting processor device, comprising: a processor; and a memory storing one or more programs, wherein the one or more programs are configured to be executed by the processor, the one or more programs including instructions for: extracting, using a colored image and a depth image of a real object, diffuse lighting information applied to the real object; recovering a diffuse image with respect to the real object, based on the extracted diffuse lighting information; and generating a speculum image based on a calculated difference between the recovered diffuse image and the colored image, and a shadow image based on the recovered diffuse image and the colored image, wherein the speculum image is generated from an error image between the colored image and the diffuse image recovered by the diffuse image recovery unit, and wherein an illuminance of a lighting environment applied to the real object is based on an illuminance of the lighting, a total number of lightings, the colored image, a total number of diffuse lighting constants constituting a diffuse reflection lighting environment, a model expressing a diffuse reflection, a model expressing a specular reflection, a diffuse lighting constant, a direction of light of the lighting constituting a specular reflection lighting environment, a depth value of the depth image, and a view point.
