PROBLEM TO BE SOLVED: To provide a technique of gesture interface for supporting operation input by user gesture.SOLUTION: A distance calculation unit 20 obtains, from a gesture image obtained by capturing an image of user gesture performed while watching a three-dimensional display, a distance of the user gesture in depth direction. A gesture recognition parameter adjustment unit 50 adjusts, on the basis of the resolution of distance measurements in depth direction, a parameter when recognizing operation input by user gesture. A gesture recognition processing unit 60 refers to, under an adjusted parameter, a distance in depth direction calculated by the distance calculation unit 20, to recognize operation input by user gesture. |
