Description

この課題を解決するため、例えば本発明のハンドジェスチャ認識装置は以下の構成を備える。すなわち、
撮像手段で時系列に撮像された画像中の、少なくとも１人のユーザの顔領域を検出する顔検出手段と、
前記顔検出手段で検出された顔領域それぞれに対し、予め定義された顔領域との相対的位置情報が示す前記画像中の領域を、該顔領域に対応するユーザが行うハンドジェスチャを検出するための検出領域として決定する決定手段と、
前記撮像手段で時系列に撮像された画像のうち、前記決定手段によって決定される１以上の検出領域内で検出されるユーザの手の移動軌跡に基づいて、前記ユーザが行うハンドジェスチャを認識する認識手段を備え、
前記認識手段は、前記検出領域内から検出される前記ユーザの手の画像の移動軌跡のうち、前記検出領域の外部から内部に侵入する移動の軌跡は、前記ハンドジェスチャを認識する処理の対象としないことを特徴とする。 In order to solve this problem, for example, the hand gesture recognition device of the present invention has the following configuration. That is,
In images captured in time series by an imaging unit, a face detecting unit that detects a face area of at least one user,
For each detected face area in the face detecting section, a region in the image represented by the relative position information of the predefined facial area, for detecting the hand gesture performed by the user corresponding to said pigment region Determining means for determining as a detection area;
The hand gesture performed by the user is recognized based on the movement trajectory of the user's hand detected in one or more detection areas determined by the determination unit among the images captured in time series by the imaging unit. With recognition means,
The recognizing unit is configured to recognize a movement trajectory that enters the inside of the detection region from the outside of the detection region of the image of the user's hand detected from the detection region. It is characterized by not .
