Stereoscopic computer graphics moving image generating apparatus

A stereoscopic computer graphics moving image generating apparatus comprising:

• projection transformation means for generating a two-dimensional projection image as viewed from a camera using three-dimensional structural information of a subject;
• rendering means each for calculating a viewable image from the output of said projection transformation means;
• object sequence generating means for generating an object sequence defining said three-dimensional structural information and capable of generating a moving image by varying said three-dimensional structural information;
• motion calculating means for calculating at least one of the motion and motion parallax of a displayed subject using at least one of said three-dimensional structural information, the output of said projection transformation means, the output of said rendering means, and the output of said object sequence generating means;
• and
• object motion correcting means for correcting the object sequence so that at least one of the motion and motion parallax of the displayed subject does not exceed a tolerance range of sense of a viewer, wherein said sense includes at least one of a sense of motion and a sense of depth, and said tolerance range of said sense of motion of a viewer corresponds to said motion, and said tolerance range of said sense of depth of a viewer corresponds to said motion parallax.
