电子屏幕对宝石颜色的不同显示效果

Different Display Effects of Gemstone Color on Electronic Screens

颜色是评价宝石质量的重要指标,颜色的好坏直接影响宝石的市场价格。信息时代,大量的宝石图片信息需要显示在电子屏幕中,由于电子屏幕的参数差异,同一张宝石图片在不同的电子屏幕中往往显示效果是不同的,定量分析电子屏幕对宝石颜色显示效果的影响具有很高的实用价值。本文以一张包含6颗不同颜色(红、橙、黄、绿、蓝、紫)的彩色宝石的图片作为初始图像,将其导入并显示在手机屏幕中,固定相机拍摄条件系统地记录了不同参数的屏幕中彩色宝石图片的显示效果。基于拍摄到的图片信息,运用CIE L^(*)a^(*)b^(*)颜色模型对显示效果进行了定量评价,分析了屏幕亮度、色调、型号以及有无防蓝光膜等对图片中不同颜色宝石的色调影响。本文的研究结果有助于人们直观地感受电子屏幕中彩色宝石颜色显示效果的差异性,同时也可以为彩色宝石图片的展示提供最优化的电子屏幕方案。

Color is an important indicator for evaluating the quality of gemstones,which directly affects the market price of gemstones.In the information age,a large amount of information about gemstones needs to be displayed on the electronic screen.Due to the differences in the parameters of the electronic screen,the display effect of the same gemstone picture on different electronic screens is also different.It is of high practical value to quantitatively analyze the influence of electronic screen on the color display of gemstones.In this paper,a picture of 6 gemstones with different colors(red,orange,yellow,green,blue,and purple),which was used as the initial image,was imported and displayed on the mobile phone screen.The pictures of colored gemstones displayed on the screen were systematically recorded by a camera with fixed shooting parameter.Based on the information of captured picture,the CIE L^(*)a^(*)b^(*) color model was used to quantitatively evaluate the color reproduction effect,and the influence of parameters such as screen brightness,hue,model,and the presence or absence of anti-blue light film on the hue of different colored gemstones was analyzed.The research results will help people to intuitively feel the difference in the color display effect of colored gemstones on the electronic screen,and can also provide an optimized electronic screen solution for the display of colored gemstone pictures.
