PROBLEM TO BE SOLVED: To provide a method for obtaining an image capable of accurately measuring the colors of a subject even when the direction of a subject and the direction of a color chart is different from each other.SOLUTION: The processor determines whether or not a subject 70 as an object of color measurement and a color chart 66 the color measurement values of which are known are subjected to a direct light from a light source. The processor acquires an image 4, in which the subject 70 and the color chart 66 are picked up under the above conditions, as an image for carrying out color correction to obtain a color measurement values of the subject 70 based on the colors in an area 6 corresponding to the subject 70 in the image 4 based on the colors in an area 8 corresponding to the color chart 66 in the image 4 and color measurement value of the color chart 66.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】被写体の向きと色票の向きが相違している場合にも、被写体の色を精度良く計測可能な画像を得る方法を提供する。【解決手段】処理装置は、測色対象の被写体70及び測色値が既知の色票66が共に光源からの直接光が照射されていない状況か否かを判定し、前記状況で被写体70及び色票66を撮像した画像4を、当該画像4中の色票66に対応する領域8の色及び色票66の測色値に基づき、画像4中の被写体70に対応する領域6の色から被写体70の測色値を求める色補正を行うための画像4として取得する。【選択図】図3
