<p>PROBLEM TO BE SOLVED: To improve accuracy for recognizing a gesture operation in response to disturbance light or a motion of an object.SOLUTION: An image recognition apparatus according to the present invention includes: an image selection unit that determines which image type a picked-up image photographed in an environment in which an irradiation device is periodically turned on and off belongs to, a light-on picked-up image when the irradiation device is turned on or a light-off picked-up image when the irradiation device is turned off; a motion-vector calculation unit that calculates a motion vector of an object using a plurality of picked-up images in the same image type; a differential-image generation unit that generates a corrected picked-up image by moving a position of the object included in the picked-up image on the basis of the motion vector, and that generates a differential image between the picked-up image and the corrected picked-up image; an object recognition unit that calculates features of a shape and a motion of the object from the differential image, and that outputs a recognition result indicating types of the shape and a hand motion of the object on the basis of the features; and an operation determination unit that determines an operation content from the object recognition result, and that generates and outputs a command indicating the determined operation content.</p> |
