用屏幕色度计对一台SONY-G520显示器的显色特性进行了测量,研究了其开机稳定性和短、中、长期内的色差及色度偏差。实验结果表明,开机后,显示器的亮度Y和色度x,y分别可在2h,30min和1h达到相对稳定状态,且在达到相对稳定后,在短、中、长期内的平均色差分别为0.0611,0.1469和1.2536CIELAB色差单位;在中期内,Y,x,y,L,a,b的平均偏差分别为0.0663,0.0008,0.0015,0.0695,0.4740和0.1766。通过对显示器稳定性的测量,为在对比度敏感测量和色貌模型、图像质量、图像感知模型评价等研究领域中用显示器进行实验研究奠定了基础。
The colorimetric characteristics of a SONY-G520 display were measured with a screen colorimetric meter, and the stability of the power on and the color difference and chromaticity deviation in short, medium and long term were studied. The experimental results show that the brightness of display Y and chromaticity x, y can reach relatively stable state at 2h, 30min and 1h, respectively, and the average chromatic aberration in the short, middle and long term are 0.0611 , 0.1469 and 1.2536CIELAB color difference units; in the medium term, the mean deviations of Y, x, y, L, a and b were 0.0663, 0.0008, 0.0015, 0.0695, 0.4740 and 0.1766, respectively. By measuring the stability of the display, it laid the foundation for the experimental study of the display in the field of contrast-sensitive measurement and color appearance model, image quality and image perception model evaluation.
