Summary:To provide an image processing device capable of efficiently executing biological determination in a situation in which a photographing condition changes.SOLUTION: An image processing device for determining whether a person in an image is a living body comprises: decision means for deciding a threshold value indicating a skin color range in a time-series image acquired at a prescribed time; acquisition means for acquiring color information about a skin color region included in the time-series image on the basis of the threshold value; and determination means for determining whether or not to continue biological determination processing for determining whether the person of the time-series image is a living body on the basis of the color information.SELECTED DRAWING: Figure 2 【課題】 撮影条件が変化する状況においても生体判定を効率的に実行できる。【解決手段】 本発明に係る画像処理装置は、画像の人物が生体であるか判定する画像処理装置であって、所定時間において取得された時系列画像における肌色の範囲を示す閾値を決定する決定手段と、前記閾値に基づいて、前記時系列画像に含まれる肌色領域についての色情報を取得する取得手段と、前記色情報に基づいて、前記時系列画像の人物が生体であるかを判定する生体判定処理を継続するか否かを判定する判定手段と、を有することを特徴とする。【選択図】 図2
