3-DIMENSIONAL IMAGE PROCESSING METHOD, 3-DIMENSIONAL IMAGE PROCESSING DEVICE, AND 3-DIMENSIONAL IMAGE PROCESSING SYSTEM

Illumination light having a 2-dimensional luminance distribution is used for obtaining photographed image data, and surface attributes of a real object are estimated based on photography environment information such as information relating to the luminance distribution of the illumination light at the time of photography, along with the photographed image data. This solves a problem with 3-dimensional image processing devices which obtain information relating to surface attributes of a real object from photographed image data obtained by photographing the real object along with the 3-dimensional shape of the real object and reproduce the object as a 3-dimensional image on a display screen, wherein specular reflection may not be captured in the photographed image data with objects having metal glossiness or the like where the specular reflection only occurs at an extremely narrow angle range at the time of obtaining the surface properties, resulting in erroneous information with no specular reflection being input. Thus, photographed image data of the real object is obtained without failing to pick up any specular reflection light.
