Title: Three-dimensional image processing apparatus for jointed objects

Abstract: An image processing apparatus has a three-dimensional joint position storing circuit for storing a three-dimensional coordinate position for each of available joints of an object at each frame for a standard action; a geometric data storing circuit for storing geometric data for at least a portion of the object based on unique coordinate systems for each of the available joints; a unique coordinate system determining circuit for determining the unique coordinate system for each of the available joints based on the stored three-dimensional coordinate positions; a three-dimensional joint angle computing circuit for computing a three-dimensional joint angle for at least one of the available joints based on a desired mode of action modification and the determined unique coordinate systems; a joint angle displacing circuit for displacing the three-dimensional joint angle for at least one of the available joints; a unique coordinate system generating circuit for generating the unique coordinate system for at least one of the available joints; and an action synthesizing circuit for assigning the geometric data corresponding to each of the available joints.
