Stereoscopic computer graphics image generating apparatus and stereoscopic TV apparatus

A stereoscopic computer graphics (CG) image generating apparatus for placing an object within a binocular fusion range of a viewer, the object being at a distance from an imaginary camera, comprising:

• a stereoscopic image display device having a screen for displaying a stereoscopic image of said object;
• distance information extraction means for extracting a near point, corresponding to a shortest distance between said imaginary camera and said object, and a far point corresponding to a longest distance between said imaginary camera and said object;
• fusional range computing means for determining the binocular fusional range of the viewer viewing the screen of the stereoscopic image display device based on the near point, the far point, and at least one of a plurality of human binocular fusional limit characteristic data responsive to a viewing angle of the screen;
• camera parameter calculating means for calculating a plurality of parameter conditions of said imaginary camera, based on said binocular fusional range and the shortest and longest distances between said imaginary camera and said object;
• camera parameter determining means for receiving said parameter conditions from the camera parameter calculating means and determining which of said parameter conditions places said object within the binocular fusional range of the viewer;
• and
• projection transformation means for generating a plurality of two-dimensional projection images of said object as viewed from said imaginary camera in response to said determined parameter conditions, the two-dimensional projection images being displayed on the stereoscopic image display device.
