An image processing apparatus processes image information that includes pixels each of which have X-axis and Y-axis coordinates. The apparatus includes a circuit for processing the image information in an X-axis direction, a circuit for processing the image information in a Y-axis direction and a circuit for adding a predetermined value representing a coordinate in a Z-axis direction to each of the pixels of the image information so that the image information is expressed in three dimensions. In this way information representing a two-dimensional primitive image is transformed into pseudo three-dimensional image information that can be combined with three-dimensional images.
