摘要

P To provide a gloss feeling evaluation method capable of achieving better correspondence with gloss feeling that humans feel, compared to conventional methods, by calculating gloss feeling by a single evaluation device using information of lightness components and chromaticity components of regularly reflected light and diffuse reflected light considering gloss variations and the like, a gloss feeling evaluation device, an image evaluation device provided with the device, an image evaluation method and a PROGRAM for performing the method. PSOLUTION: The gloss feeling evaluation method for determining a gloss feeling evaluation value of an object based ON each of lightness components and chromaticity components of captured color images of regularly reflected light and diffuse reflected light from the object determines the gloss feeling evaluation value of the object by referring a gloss variation evaluation value based ON the lightness components obtained from the regularly reflected light, a gloss reference value based ON the lightness components of the regularly reflected light and the diffuse reflected light and a chromaticity change amount indication value relating to the change amount of the color of the regularly reflected light and the diffuse reflected light.

提供一种光泽感评价方法,与传统方法相比,该方法能够通过使用单个反射装置使用正反射光和漫反射光的亮度成分和色度成分的信息来计算光泽感,从而与人类感觉的光泽感更好地对应。考虑光泽变化等的反射光,光泽感评价装置,具有该装置的图像评价装置,图像评价方法和用于执行该方法的程序。

解决方案:用于基于物体的正反射光和漫反射光的捕获彩色图像的亮度分量和色度分量中的每一个来确定物体的光泽感评估值的光泽感评估方法确定光泽感评估值通过参考基于从正反射光获得的亮度分量的光泽度变化评估值,基于正反射光和漫反射光的亮度分量的光泽度参考值以及与正反射光和漫反射光的颜色变化量。
