Abstract: A key region extraction unit (303) extracts a first region including pixels having a predetermined pixel value in a physical space image. A motion vector detection unit (304) calculates motion vectors at a plurality of portions on the physical space image. An object region detection unit (305) specifies, using the motion vectors, a second region to be merged with the first region. When superimposing a virtual space image on the physical space image, an image composition unit (308) excludes a composition region obtained by merging the first region with the second region from a virtual space image superimposition target.

Abstract: In an image processing method of determining the positional relationship among virtual objects in virtual space and generating a virtual shadow of the virtual objects, a plurality of virtual objects are rendered in a first plane to which a first axis passing through a virtual light source is normal, and the positional relationship among the plurality of virtual objects is determined based upon the result of rendering acquired. Shadow information of the plurality of virtual objects is generated using the result of acquired rendering.

Abstract: An analyzation apparatus which performs an analysis simulation in accordance with analysis condition data. An analysis condition modeling unit generates an analysis condition model data by assigning an analysis condition to each region of a three-dimensional model represented with analysis object model data of the analysis simulation based on analysis condition data set for the analysis simulation. A rendering unit renders the three-dimensional model represented with the analysis condition model data and displays the three-dimensional model on a display device.
