Abstract

The input device and the input system include a hand detection means which detects the position of the hand, a body part detection means which detects positions of user's body parts such as the face, for example, a relative position calculation means which calculates a relative position of the hand with respect to body parts from hand position information being a detection result of the hand detection means and body part position information being a detection result of the body part detection means, and a gesture recognition means which recognizes a hand gesture on the basis of a change in the hand position information being the detection result of the hand detection means, wherein when a hand gesture is recognized, the operation of the input device with respect to the user's gesture is changed according to a relative position of the hand with respect to body parts.

First claim

What is claimed is:

1. An image processing device which outputs an image signal, the image processing device including:
a camera configured to capture an image including that of a user therein;
a portion detecting unit, which is configured to detect positions of a hand and a face of the user from the image, which is captured by said camera; and
an operation recognizing unit configured to recognize a gesture of the user determine one (1) menu corresponding to said gesture, for a video signal showing plural numbers of menus therein, which is outputted by said image processing device, wherein
said operation recognizing unit determines a boundary line at a position separated from the position of the face, which is detected, in a left-hand direction by a predetermined distance therebetween, when the gesture is made by a left hand of the user,
said operation recognizing unit determines a boundary line at a position separated from the position of the face, which is detected, in a right-hand direction by a predetermined distance therebetween, when the gesture is made by a right hand of the user, and
said operation recognizing unit determines a first menu when the position of the hand making the gesture is detected within a first region, which is divided by the boundary line determined, while determines a second menu when the position of the hand making the gesture is detected within a second region, which is divided by the boundary line determined.

2. The image processing device according to claim 1 ,
further including an image processing unit configured to process the image signal to be output,
wherein the image processing unit processes the image signal in such a manner that a fact is indicated that the menu is determined by said operation recognizing unit.

3. The image processing device according to claim 1 ,
wherein said operation recognizing unit determines the boundary line in vicinity of a left shoulder when the user makes the gesture by the left hand, while determines the boundary line in vicinity of a right shoulder when the user makes the gesture by the right hand.
