This paper educes the method for computing picture definition of DTV and its theoretical value which is expressed in TV line, and indicates that CRT TV based on electronic scanning is greatly different from those TV display devices or screens with intrinsic resolution such as LCD, PDP, DLP and LCoS in picture definition.
导出了以电视线表示的数字电视图像清晰度计算方法及其理论值,指出基于电子束扫描的CRT电视显像管与LCD,PDP,DLP,LCoS和OLED等固有分辨力显示器(屏)所显示图像的清晰度之间有很大不同,而测定电视图像清晰度不仅要合理设计和精确生成清晰度测试图,而且必须在规范的测试条件下采用正确的方法,并对测试数据进行处理。
