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。
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 characteristics. Thus a more canonica showing performance of LED display like mage according to the LED monitors＇ displaying and comprehensive estimation is given to the uniformity, contrast ration and color reducibility.
