Claim One:
1. A gesture recognition apparatus comprising: a first detector configured to detect a detection area including a portion of a body of an operator in a first image of a motion image captured at a first resolution; a second detector configured to detect an auxiliary area including an auxiliary portion used for detecting the portion in a second image of the motion image captured at the first resolution when the detection area cannot be detected from the first image of the motion image; a physical controller configured to control, when the auxiliary area is detected, a capturing unit to capture a third image of the motion image, which is an image in the frame next to the second image and is captured at a second resolution higher than the first resolution, by capturing an area estimated from a predetermined positional relationship between the portion of a body and the auxiliary portion; a third detector configured to detect the detection area in the third image; and a gesture recognizer configured to recognize a gesture of the portion based on an entire area of the first image when the detection area is detected from the first image and based on the detection area of the third image when the detection area cannot be detected from the first image.
