A stereoscopic vision parameter is determined on the basis of the 3D space data to be displayed and the disparity distance at which the left- and right-eye images look displaced from each other in a predetermined 2D rendering space. In determining a parameter, the disparity distance between left and right image data of an object point in the 3D space is set in advance, which appears when the image data are rendered in the 2D rendering space, and the position of a displaced point which is separated from the coordinates of the object point in the 2D rendering space in the base line length direction of the observer by the disparity distance is computed. The coordinates of this displaced point in a 3D space are computed. In addition, the base line length is determined on the basis of the distance between the 3D coordinates of the displaced point and the object point.
