A dress that is orange under a high pressure sodium lamp may turn red under daylight. Two paint samples that look alike under a high pressure sodium lamp may display different colors under daylight. Everyday examples show that more than one aspect need to be considered in the study of color rendering. While addressing different aspects of the subject, several measures have been developed.〔Commission International de l'Eclairage 1995.〕 The color rendering capacity is one of these measures, specially devised to deal with a particular aspect of the color rendering quality of light sources. == What is the color rendering capacity == How many colors on earth is a given light source capable of vividly rendering? Under what type of light source can a scene be made the most colorful? Such questions highlight a particular aspect of the color rendering quality of light sources,〔MacAdam 1981, p.103.〕 an aspect relating to the concern of whether differently colored objects under illumination of a certain light source can appear in colors that are significantly different from each other and occupying a wide range of colors. The color rendering capacity is one of several measures of the color rendering quality of light sources, specially devised to be able to answer the above questions. The idea of the color rendering capacity can be introduced as follows: Associated with each type of spectral power distribution, one and only one color solid can be constructed in a uniform color space.〔MacAdam 1981, p. 157.〕 It has been proved that this color solid comprises all the object colors producible under illumination of that spectral power distribution with one unit luminous flux,〔MacAdam 1981, p. 106.〕 and the volume of the color solid determines the upper limit for the number of the object colors producible under the given spectral power distribution with one unit luminous flux.〔Xu 2010, p. 29.〕 This volume of the color solid associated with the spectral power distribution is called the color rendering capacity.〔Xu 2010, p. 37.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Color Rendering Capacity」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
