| 摘 要： | 当前户外LED显示屏的图像质量主要靠业内人士进行简单的主观评价，不确定因素多，尚未形成规范的评价标准。本文参考通用的图像质量主观评价方法，针对LED显示屏显示特性，探讨了主观评价中的各个环境因素的控制方法，并定义了一系列主观评价测试图像的类型，能对显示屏的均匀性、对比度、色彩还原性等显示性能进行更规范更全面的评价。

| Abstract: | Currently,the image quality of a outdoor LED display is mainly evaluated subjectively by the professionals.As with many uncertain factors,there has not been a standard evaluation criterion yet.This paper,with reference to the general evaluation methodology,investigates the environmental controlling methods in subjective evaluation and defines a series of types of test image according to the LED monitors’ displaying characteristics.Thus a more canonical and comprehensive estimation is given to the showing performance of LED display like uniformity,contrast ration and color reducibility. |
