Latest Patents

Matsumura's latest patents include an image processing apparatus and method that features a key region extraction unit. This unit extracts a first region that includes pixels with a predetermined pixel value in a physical space image. Additionally, a motion vector detection unit calculates motion vectors at various portions of the physical space image. An object region detection unit specifies a second region to be merged with the first region using these motion vectors. When superimposing a virtual space image on the physical space image, an image composition unit excludes the merged region from the virtual space image superimposition target. Another patent involves an image processing method that determines the positional relationship among virtual objects in virtual space and generates virtual shadows for these objects. This method renders multiple virtual objects in a plane normal to a first axis passing through a virtual light source, allowing for accurate shadow generation based on the rendering results.
