The basic measurement of a color stimulus is its spectral power

distribution as a function of wavelength (or frequency). The spectral power

distribution of a reflecting surface is the product of the spectral power

distribution of the illumination and the spectral reflectance factor

of the surface. Although the same spectral power

distribution may produce different color sensations,

depending on its surround, background, illumination,

and viewing geometry, all physical specifications of

color stimuli start from their spectral power

distributions. The link between the objective physics and

the subjective perception is provided by photometry

and colorimetry. These two fields of scientific study

attempt to quantify equivalent capacities of light stimuli

in producing our color sensations. Because the incomplete

knowledge we have in the total process of color perception,

the initial goals of photometry and colorimetry have been intentionally

limited to the physical specifications of colors, without

addressing the issues of color appearances. However, even

with this limited scope of study, their applications to

practical problems have been widely accepted and the results

have been quite useful. In this chapter, we will review

the basis of colorimetry and describe some of its applications.

Colorimetry is a scientific field in which physical specifications

of light stimuli are studied for matching the corresponding

color sensations under restricted viewing conditions. In particular,

it seeks to represent the spectral power distribution of any incident light

with a much reduced number of parameters (almost always three, and

sometimes four, corresponding to the number of photoreceptor types

we believe are facilitating the sensation of color under the given

conditions).

    顏色刺激的基本的測量是它的鬼功率分配作為波長(或頻率功能) 。反射的表面的鬼功率分配是鬼功率分配照明和表面的鬼反射率因素的產品。雖然同樣鬼功率分配也許導致不同的顏色感覺, 根據它圍攏, 背景, 照明, 並且觀察幾何, 顏色刺激的所有物理規格開始從他們的鬼功率分配。鏈接在客觀物理和主觀悟性之間由光度學和色度學提供。這兩個科學研究的領域試圖定量輕的刺激等效容量在導致我們的顏色感覺。由於我們有在顏色悟性的總過程的殘缺不全的知識, 光度學和色度學的最初的目標對顏色的物理規格故意地被限制了, 沒有論及顏色出現的問題。但是, 以這有限的範圍研究, 他們的申請對實用問題廣泛被接受了並且結果是相當有用的。在這個章節裡, 我們將回顧色度學的依據和將描述一些它的應用。

    色度學是輕的刺激物理規格被學習的匹配對應的顏色感覺在有限的觀察情況下的科學領域。特別是, 它尋求代表任一入射光的鬼功率分配參量的一個被減少的數字(幾乎總三, 和有時四, 對應於的光感受器類型的數量我們相信促進顏色的感覺在指定的條件下) 。
