IMAGE PROCESSING DEVICE, CONTROL METHOD FOR IMAGE PROCESSING DEVICE AND INFORMATION RECORDING MEDIUM

摘要

An image processing device is provided for enabling the realization of a shading expression on an object surface while promoting the ease of a load of image processing and for enabling the promotion of ease of wrongness that users feel. A shading process executing unit (62) carries out shading of the object surface in accordance with a quasi normal vector of each pixel of a texture image subjected to mapping on the object surface. A shading process execution limiting unit (66) limits the execution of shading process by the shading process executing unit (62) in accordance with a distance from a view point to the object. A quasi normal vector acquiring unit (60) stores information to make the distance from the view point correspond to quasi normal vector information to acquire a quasi normal vector of each pixel. Further, the quasi normal vector acquiring unit (60) acquires the quasi normal vector of each pixel in accordance with the quasi normal vector information corresponding to the distance from the view point to the object.
