<P>PROBLEM TO BE SOLVED: To recognize motion of a person even when it is difficult to discriminate a face area from the other areas with color information when motion of the person is recognized using video. Ž<P>SOLUTION: An action estimation device 205 divides each image obtained by high-resolution cameras 211 and 213 into a plurality of small areas, and associates the small areas of images with each other, which are recognized to include the same portion of a person. Then, a distance between correspondence points of the associated two small areas is calculated as parallax. Next, parallax of a face area obtained by imaging the face of the person is compared with parallax of a flesh color area obtained by imaging a flesh color portion other than the face of the person, and a flesh color area having parallax close to the parallax of the face area around the face area is detected as an arm area. The motion of an arm of the person is recognized on the basis of a relative position of the arm area with respect to the face area, and a difference between the parallax of the face area and the parallax of the arm area.
