清晰度是电视系统或电视设备最重要的性能指标,下面谈谈彩电清晰度的几个问题。一、什么是清晰度清晰度是人眼对客观图像的主观评价,而图像的清晰度必须用分辨力来衡量,分辨力则表示电视系统或某个电视设备(如摄像机)对图像像素的分解能力,有些书也叫分解力。分辨力与扫描行数密切相关,扫描行数愈多分辨力愈高,分辨力越高,图像清晰度越高。
Clarity is the most important performance of the television system or television equipment, the following talk about several issues of color TV clarity. First, what is clarity? Definition is the subjective evaluation of the objective image by the human eye, and the resolution of the image must be measured by resolution. Resolution refers to the decomposition of image pixels by the television system or a television device (such as a video camera) Ability, some books are also called decomposition. The resolution is closely related to the number of scanning lines. The higher the number of scanning lines, the higher the resolution. The higher the resolution, the higher the image resolution.
