PROBLEM TO BE SOLVED: To provide a device that recognizes each of multiple teeth and measures color individually.SOLUTION: A color measuring device that sets tooth areas to an image 55 with horizontal teeth captured and measures color of each tooth area comprises: a recognition unit 33 that recognizes the tooth area from the captured image a setting unit 35 that sets a detection range of an interdental part in the captured image on the basis of the number of longitudinal pixels in the tooth area and a detection unit 36 that detects the interdental part on the basis of luminosity of each pixel in the tooth area in the detection range of the interdental part. The recognition unit 33 again recognizes a new tooth area from the tooth area with the interdental part excluded.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】複数の歯牙を1本ずつ認識して個別に測色する装置を提供する。【解決手段】横並びの歯牙を撮像した撮像画像55に対して歯牙領域を設定し、歯牙領域毎に測色する測色装置が、撮像画像から歯牙領域を認識する認識部33と、歯牙領域の縦列の画素数に基づいて、撮像画像に歯間部の検出範囲を設定する設定部35と、歯間部の検出範囲における歯牙領域の各画素の明度に基づいて、歯間部を検出する検出部36とを備え、認識部33が、歯間部を除いた歯牙領域から新たな歯牙領域を再認識する構成にした。【選択図】図3
