【摘要】：目的研究环境光以及i Pad的亮度设置对i Pad颜色特性的影响。方法测量3种常规光照环境下,14个不同的设备亮度设置下i Pad屏幕上显示色块的绝对色度值,分析不同环境光下不同设备亮度设置下i Pad的色温、对比度、通道可加性、色品恒定性以及色域等颜色特性。结果当i Pad的设备亮度小于175 cd/m2时,环境光对色温、对比度、通道可加性、色品恒定性以及色域等颜色特性有较大影响;当i Pad的设备亮度大于175 cd/m2时,环境光对i Pad的显色性能的影响较小;相同环境下,设备亮度的变化对i Pad色域以及色温产生较大影响,对其他颜色特性影响较小,设备亮度较大时,暗调部分的颜色被压缩。结论在一般环境光下,当背光源亮度设置大于175 cd/m2范围时,i Pad的显色性能较好较稳定,但部分暗调颜色被压缩。
[Abstract]:Objective to study the effect of ambient light and luminance setting of I Pad on the color characteristics of I Pad. Methods of measurement of 3 kinds of conventional lighting conditions, 14 different equipment brightness setting absolute chroma color value display I Pad screen, color, contrast analysis, channel under different ambient light brightness settings under different equipment I Pad additive, and constant chromaticity gamut and color characteristics. Results when the I Pad device brightness is less than 175 cd/m2, the environment of light color, contrast, channel additivity, and constant chromaticity color gamut characteristics have significant effect; when the I Pad device brightness is greater than 175 cd/m2, the smaller effect of ambient light color on the performance of I Pad in the same environment; change the brightness of the equipment, have a greater impact on the I Pad color gamut and color temperature, little influence on other color characteristics, the brightness of equipment is large, the color darkened part is compressed. Conclusion in general environmental light, when the backlight brightness is set greater than 175 cd/m2, the color performance of I Pad is better than the stable, but part of the darkened color is compressed.
