摘要： A texture picture with a highest resolution is selected among a plurality of pictures taken from different points of view for each patch surface, and texture mapping is carried out by pasting a texture picture selected for a patch surface on the patch surface. Then, processing is carried out to correct differences in concentration, which are caused by differences in beam-source condition, between pictures or between patch surfaces. As the correction processing, inter-frame picture-concentration-value correction, inter-patch texture-picture-shift correction and inter-patch boundary concentration smoothing correction are performed to allow texture mapping with a high picture quality to be carried out to produce a three-dimensional picture having a high quality. It is thus possible to provide a texture mapping technique capable of producing a three-dimensional picture having a high picture quality.
