Gloss value calculation device, gloss value measurement device, gloss color tone quantifier, and gloss value calculation method

摘要

An object of the present invention is to provide an apparatus for calculating a gloss value by using a method of calculating a gloss value having a higher correlation with a gloss feeling visually perceived by a person. The present invention for achieving the above object relates to a gloss value calculation device. The gloss value calculation device uses the distribution information of the brightness or the reflection intensity with respect to the light receiving angle obtained by measuring the reflected light obtained by reflecting the measurement light irradiating the object, and the peak of the brightness or the reflection intensity in the distribution information. It has a peak calculation unit for calculating the height and spread of the peak, and a gloss value calculation unit for calculating a gloss value represented by the ratio of the height of the peak to the spread of the peak.
