PROBLEM TO BE SOLVED: To provide an information processing device capable of improving the accuracy of discriminating a human motion. An information processing apparatus includes a distance image acquisition unit that acquires a distance image of a predetermined region including a bed, a processing range setting unit that sets a processing region including a bed in the distance image, and a distance image based on the distance image. A detection unit that detects a motion of a person within the set processing area. Then, the processing range setting means receives the designation of the outer edge portion of the processing area located outside the bed, and sets the processing area according to the received designation of the outer edge portion. [Selection diagram] Figure 2【課題】人の動作の判別精度の向上を図ることができる情報処理装置を提供する。【解決手段】情報処理装置は、寝床を含む所定領域の距離画像を取得する距離画像取得手段と、距離画像内における寝床を含む処理領域を設定する処理範囲設定手段と、距離画像に基づいて、設定された処理領域内の人物の動作を検出する検出手段と、を備える。そして、上記処理範囲設定手段は、寝床の外側に位置する処理領域の外縁箇所の指定を受け付けて、当該受け付けた外縁箇所の指定に応じて処理領域を設定する。【選択図】図２
