Gesture operation input processing apparatus and gesture operation input processing method

1. A gesture operation input processing apparatus comprising:

an instruction point extraction unit configured to extract an instruction point of a user from an image in which a gesture of the user made while the user is looking at a display is captured;

a distance calculation unit configured to obtain a distance to the instruction point in the depth direction;

a parameter adjustment unit configured to adjust a parameter related to detection sensitivity in the depth direction when operation input by the gesture of the user is recognized, based on at least one of resolution of distance measurement in the depth direction and three-dimensional display performance of a display; and

a gesture recognition processing unit configured to recognize the operation input by the gesture of the user based on the adjusted parameter, and to detect whether the instruction point of the user passes through one or more of a plurality of virtual screens set in the depth direction, based on the distance to the instruction point in the depth direction calculated by the distance calculation unit,

wherein the parameter adjustment unit adjusts, as the parameter related to the detection sensitivity in the depth direction, at least one of an installed number, an installation interval, and dead band of the plurality of virtual screens provided in the depth direction for allowing the instruction point to pass through.

2. The gesture operation input processing apparatus according to claim 1 , wherein the gesture recognition processing unit activates the instruction point so as to recognize operation input entered by a gesture when the instruction point passes through one or more of the plurality of virtual screens.

3. The gesture operation input processing apparatus according to claim 1 , wherein the parameter adjustment unit makes, when the display allows for three-dimensional display compared to when the display allows for two-dimensional display, at least one adjustment of: increasing the installed number; reducing the installation interval; and reducing the dead band of the virtual screens.

4. The gesture operation input processing apparatus according to claim 1 , wherein the parameter adjustment unit sets, when the distance measurement in the depth direction is conducted by a measurement method of a TOF (time of flight) type, the installed number, the installation interval, and the dead band of the virtual screens to be constant with respect to the distance in the depth direction.

5. The gesture operation input processing apparatus according to claim 1 , wherein, when the distance measurement in the depth direction is conducted by a measurement method of a triangulation type, the parameter adjustment unit sets the installed number, the installation interval, and the dead band of the virtual screens to be variable with respect to the distance in the depth direction.

6. A gesture operation input processing method in a three-dimensional gesture input system provided with an interface for supporting operation input entered by a gesture of a user, the method comprising:

extracting an instruction point of a user from an image in which a gesture of the user made while the user is looking at a display is captured;

obtaining a distance to the instruction point in the depth direction;

adjusting a parameter related to detection sensitivity in the depth direction when operation input by the gesture of the user is recognized, based on at least one of resolution of distance measurement in the depth direction and three-dimensional display performance of a display; and

recognizing the operation input by the gesture of the user based on the adjusted parameter, and to detect whether the instruction point of the user passes through one or more of a plurality of virtual screens set in the depth direction, based on the distance to the instruction point in the depth direction,

wherein the adjusting step includes adjusting, as the parameter related to the detection sensitivity in the depth direction, at least one of an installed number, an installation interval, and dead band of the plurality of virtual screens provided in the depth direction for allowing the instruction point to pass through.
