| 目的 研究环境光以及iPad的亮度设置对iPad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iPad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iPad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iPad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iPad的设备亮度大于175 cd/m2时，环境光对iPad的显色性能的影响较小；相同环境下，设备亮度的变化对iPad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，iPad的显色性能较好较稳定，但部分暗调颜色被压缩。 |

| The work aims to study the effect of settings of iPad brightness and environment illumination on color characteristics of iPad. The absolute chromatic value of color blocks displayed on iPad with the brightness of fourteen different equipment set under three kinds of conventional lighting environments was measured. Color characteristics of iPad, such as color temperature, contrast, channel additivity, constant channel chromaticity and color gamut, with the brightness of various kinds of equipment set under different environment illuminations were analyzed. When the brightness of iPad was lower than 175 cd/m2, the environment illumination had greater impact on such color characteristics as color temperature, contrast, channel additivity, constant channel chromaticity and color gamut. When the brightness of iPad was greater than 175 cd/m2, the environment illumination had smaller impact on the coloring rendering of iPad. Under the same environment, the change in equipment brightness had greater effect on the color gamut and color temperature of iPad and had smaller effect on other color characteristics. When the equipment brightness was larger, the color of shaded area was compressed. Under general environment illumination, when the backlight brightness set is larger than 175 cd/m2, the color rendering of iPad is better and more stable, but part of shaded colors are compressed. |
