PROBLEM TO BE SOLVED: To solve the problem of picture quality degradation in the vicinity of an object boundary in free viewpoint image synthesis technology that since a foreground color and a background color coexist in the vicinity of the object boundary, distance information contains a large estimation error and exact separation between foreground and background is difficult, resulting in picture quality degradation.SOLUTION: An image is divided into three layers: a main layer, a boundary foreground layer and a boundary background layer. Distance information based three-dimensional model generation and rendering processing are performed on the main layer, the boundary foreground layer and the boundary background layer in that order to generate a free viewpoint image. The boundary foreground layer and the boundary background layer are calculated from an object boundary, and the three-dimensional model generation and rendering processing are performed in sub-pixel units in an attempt to improve the picture quality of free viewpoint image synthesis. |
