Abstract
The invention relates to a picture synthesizing apparatus for cutting out the background from a picture depending on the move of the viewing point, and presents a picture synthesizing apparatus capable of synthesizing a picture by hidden surface processing, processing of reflection motion by contact, or the like, which is mutual interference of background and foreground, wherein a background picture corresponding to the viewing field is cut out by a background cut-out unit from a background picture in a wide range stored in a background picture store, the shape and position information of moving object of foreground is generated in a moving foreground object generating unit, the interference of depth information corresponding to background picture from a background depth store and foreground object information is calculated in a background and foreground synthesizing unit, and a picture is synthesized by hidden surface processing or processing of change of moving direction of foreground object by reflection, so that the picture can be synthesized not as a shape such as column and plane, but in consideration of a picture hiding the foreground by the background, pass-through, and reflection of foreground object colliding against the background by making use of its undulation information.
