Abstract

In a controller, a three-dimensional shape defined by at least one polygon is set on the basis of a signal from an input unit, and in a three-dimensional rendering unit, a three-dimensional image corresponding to the three-dimensional shape is rendered on the basis of a vertex of the polygon forming the three-dimensional shape, a pixel value at the vertex, and the like. The three-dimensional image is outputted as a key signal to a mixing unit for mixing images. Thus, various key signals are generated at high speed.
