上海佳實(shí)WG-20便攜式色差儀的色度空間設(shè)計(jì)

上海佳實(shí)電子科技有限公司的色差儀所使用的Lab、RGB和CMYK等色度空間是如何設(shè)計(jì)的？

色差儀的顏色檢測的基本理論依據(jù)如下，目前工業(yè)使用色差儀器內(nèi)部有種或多種色度空間。這種色度空間也被成為裝置立色彩空間，裝置立的色彩空間對于顏色檢測儀器時(shí)間正確可靠測量來說重要。裝置立色彩空間主要用于色彩模塊在系統(tǒng)RGB和CMYK模塊之間轉(zhuǎn)換。由RGB與CMYK兩種不同格式所產(chǎn)生的色彩將因裝置與裝置間的不同而有差異，這就是裝置所屬色彩空間的特性。
由人類眼睛感知后的真實(shí)色彩陳述，就是色差儀所使用的色度空間。這些色彩陳述成為立色度空間，是由1931年由CIE發(fā)展而成，因此稱為CIE基礎(chǔ)色度空間。有了這種CIE 基礎(chǔ)色度空間色差儀就可以測量油漆、染料、油墨和其他色料的顏色，為客戶提供個(gè)色彩溝通的標(biāo)準(zhǔn)。
CIE的Lab色度空間是基于人類色感的三度色彩空間，為CIE使用的色彩空間，Lab色彩空間是基于種色彩不能同時(shí)是綠和紅色，也不能同時(shí)是藍(lán)和黃色的理論，結(jié)果可能單明暗度，描述紅綠色和黃藍(lán)色的屬性。

Chromatic space design of Shanghai Jiashi WG-20 portable colorimeter

How are the Lab, RGB and CMYK chromaticity spaces used in the color difference meter of Shanghai Jiashi Electronic Technology Co., Ltd.?

The color difference meter can realize the basic theoretical basis of color detection. At present, the industrial color difference instrument has one or more chromaticity spaces inside. This chromaticity space is also used as the device independent color space. The independent color space of the device is very important for the correct and accurate measurement of the color detection instrument time. The device independent color space is mainly used to convert various color modules between the system RGB and CMYK modules. The colors produced by the two different formats of RGB and CMYK will vary depending on the device and the device, which is the characteristic of the color space to which the device belongs.
The true color statement perceived by the human eye is the chromaticity space used by the colorimeter. These color statements became independent chrominance spaces and were developed by the International Standards Committee (CIE) in 1931, hence the CIE base chromaticity space. With this CIE Basic Chromatic Space Colorimeter, you can measure the color of paints, dyes, inks and other colorants, providing customers and suppliers with a standard for color communication.
CIE's Lab Chromatic Space is a three-dimensional color space based on human color. It is a color space widely used by CIE. The Lab color space is based on the theory that a color cannot be both green and red, and not both blue and yellow. The result may be a single shade that can be used to describe the red/green and yellow/blue properties.
