Motion of a human under various conditions is reproduced by a computer graphics and the like in a real time manner without using auxiliary means such as a light reflection marker. An action recognizing apparatus is arranged by an image input unit 1 for imaging an image containing motion of an imaging object at a plurality of imaging angles by a plurality of image sensors to thereby acquire a plurality of two-dimensional images; a two-dimensional motion detecting unit 2 for calculating a direction of motion and strength thereof of each of pixels within each of the two-dimensional images imaged, a region specifying unit 3 for specifying such a region having strength of the calculated motion larger than, or equal to a predetermined strength value; a three-dimensional motion detecting unit 4 for positioning the specific region specified with respect to the plurality of two-dimensional images, whereby a three-dimensional position of the specific region and three-dimensional motion of the specific region are calculated; a portion predicting unit 5 for predicting that the calculated three-dimensional motion corresponds to any of the portions of the imaging object; and an action reproducing unit 6 for moving a model in a simulation manner based the motion predicted by the portion predicting unit 5 with respect to each of the portions, whereby motion of the imaging object is reproduced on the model.
