GLOSS VALUE CALCULATING DEVICE, GLOSS VALUE MEASURING DEVICE, COLOR TONE QUANTIFYING DEVICE FOR GLOSSY COLOR, AND GLOSS VALUE CALCULATING METHOD

摘要

The objective of the present invention is to provide a device for calculating a gloss value using a gloss value calculating method having an enhanced correlation with an impression of gloss sensed visually by a person. The present invention for achieving this objective relates to a gloss value calculating device. The gloss value calculating device comprises: a peak calculating unit which uses distribution information of brightness or reflection intensity with respect to a light reception angle obtained by measuring reflected light resulting from the reflection of measuring light radiated at an object, to obtain the peak height and spread of the brightness or the reflection intensity in the distribution information; and a gloss value calculating unit which calculates a gloss value represented by a ratio of the peak height to the peak spread.
