PROBLEM TO BE SOLVED: To provide a finger disease state evaluation device capable of quantitatively evaluating a motion paralysis state of fingers.SOLUTION: A finger disease state evaluation device comprises: distance image capturing means 10 for capturing a distance image in which distance data on a distance to a subject is included in a pixel value of each pixel； virtual phalanx image generation means 32 for determining a phalanx position of each finger from frames of a distance image which captures moving fingers of a subject person, and generating an image of virtual phalanxes in which data on the phalanx position is included in a pixel value； virtual phalanx calculation means 33 for calculating at least one of a joint angle between virtual phalanxes, an acceleration indicating a motion state of the virtual phalanxes, and an amount of movement associated with motion of the virtual phalanxes； and finger disease state determination means 34 for comparing reference data 23 for a disease state serving as a reference for fingers with a value calculated by the virtual phalanx calculation means 33 to determine a disease state level of fingers of the subject person. The finger disease state evaluation device can quantitatively evaluate the finger disease level by comparing it with the reference level.SELECTED DRAWING: Figure 1【課題】手指の運動麻痺状態を定量的に評価できる手指病態評価装置を提供する。【解決手段】被写体までの距離データが各画素の画素値に含まれる距離画像を撮影する距離画像撮影手段１０と、被験者の運動する手指を被写体として撮影した距離画像の各フレームから各指の指骨位置を求めて、その指骨位置のデータを画素値に含む仮想指骨の画像を生成する仮想指骨画像生成手段３２と、仮想指骨間の関節角度、仮想指骨の運動状態を表す加速度、及び、仮想指骨の運動に伴う移動量の少なくとも１つを算出する仮想指骨演算手段３３と、手指の基準となる病態での基準データ２３と、仮想指骨演算手段３３が算出した値とを比較し、被験者の手指の病態レベルを判定する手指病態判定手段３４とを備える。この手指病態評価装置では、手指の病態レベルを基準レベルと比較することで定量的に評価できる。【選択図】図１
