PROBLEM TO BE SOLVED: To precisely detect a skin region while suppressing electric power consumption.SOLUTION: A light source group 23 has a plurality of irradiating parts for irradiating a body to be photographed with a light of a first wavelength in respectively different directional characteristics. A light source group 24 has a plurality of irradiating parts for irradiating the body to be photographed with a light of a second wavelength being longer wavelength than the first wavelength in respectively different directional characteristics. An LED controlling part 22 controls light outputs of respective irradiating parts of the light source groups 23 and 24 in accordance with the distance to the body to be photographed, and an image photographing part 26 forms a first image obtained by photographing the body to be photographed when the light of the first wavelength irradiates the body to be photographed, and forms a second image obtained by photographing the body to be photographed when the light of the second wavelength irradiates the body to be photographed. An image processing part 28 detects a skin region based on the result of comparison between the difference of the first image and the second image and the threshold value to be compared with difference. The present invention can be applied, for example, to a detecting apparatus for detecting the movement of a hand of a human being or the like.COPYRIGHT: (C)2012,JPO&INPIT【課題】消費電力を抑えつつ、肌領域を精度良く検出する。【解決手段】光源群23は、それぞれ異なる指向特性で第1の波長の光を被写体に照射する複数の照射部を有し、光源群24は、それぞれ異なる指向特性で第1の波長よりも長波長である第2の波長の光を被写体に照射する複数の照射部を有し、LED制御部22は、被写体までの距離に応じて、光源群23及び24それぞれの照射部の光出力を制御し、撮像部26は、第1の波長の光が被写体に照射されているときに被写体を撮像して得られる第1の画像を生成するとともに、第2の波長の光が被写体に照射されているときに被写体を撮像して得られる第2の画像を生成し、画像処理部28は、第1の画像と第2の画像との差分と、差分と比較される閾値との比較結果に基づいて、肌領域を検出する。本発明は、例えば、人の手の動き等を検出する検出装置に適用できる。【選択図】図1
