INFORMATION PROCESSING METHOD IN COLOR DIFFERENCE DETERMINATION

To provide an information processing method capable of determining color difference in the same manner as the sensitivity of color difference by visual observation.SOLUTION: Color difference ΔE between measurement object portions of each geometrical optical system (e.g., an acceptance angle θ) is calculated on the basis of the received light quantity of reflected light in a plurality of geometrical optical systems, measured by a multi-angle colorimetric apparatus. Filtering is applied to the color difference ΔE, and weighting for each geometrical optical system is performed.SELECTED DRAWING: Figure 9 【課題】目視による色差の感度と同様に色差を判定することができる情報処理方法を提供する。【解決手段】多角度測色機器により測定された、複数の幾何光学系における反射光の受光量に基づいて、幾何光学系（例えば受光角θ）ごとの測定対象部位間の色差ΔＥを算出する。この色差ΔＥにフィルタリングを適用して幾何光学系ごとの重みづけを行う。【選択図】図９
