上海佳实WG-20便携式色差仪的色度空间设计
上海佳实电子科技有限公司的色差仪所使用的Lab、RGB和CMYK等色度空间是如何设计的？
色差仪的颜色检测的基本理论依据如下，目前工业使用色差仪器内部有种或多种色度空间。这种色度空间也被成为装置立色彩空间，装置立的色彩空间对于颜色检测仪器时间正确可靠测量来说重要。装置立色彩空间主要用于色彩模块在系统RGB和CMYK模块之间转换。由RGB与CMYK两种不同格式所产生的色彩将因装置与装置间的不同而有差异，这就是装置所属色彩空间的特性。
由人类眼睛感知后的真实色彩陈述，就是色差仪所使用的色度空间。这些色彩陈述成为立色度空间，是由1931年由CIE发展而成，因此称为CIE基础色度空间。有了这种CIE 基础色度空间色差仪就可以测量油漆、染料、油墨和其他色料的颜色，为客户提供个色彩沟通的标准。
CIE的Lab色度空间是基于人类色感的三度色彩空间，为CIE使用的色彩空间，Lab色彩空间是基于种色彩不能同时是绿和红色，也不能同时是蓝和黄色的理论，结果可能单明暗度，描述红绿色和黄蓝色的属性。
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.
