| 摘 要： | 图象质量的主观评价按评价方法的单项要素有；色纯，会聚，高度和色度分量间的重合，灰度绝调，几何失真和图象重显度，灰度重现，彩色满意度，图象干扰等，此外还有“清晰度”和总的图象质量”，在其它要素较好的情况下，这两个要素决定了彩电的技术水平，为提高图象质量采用了各种动态调整技术。

| Abstract: | Individual elements for subjective assessment of picture quality according to the method of assessment include: color purity, convergence, coinsidence between luminance and chrominace components, unified adjustment of gray scales, geometric distortion and picture reproduction rate, gray scale reproduction, color satisfaction, picture interference and etc. In addition, there are also definition and total picture quality. Under the condition of that other elements are relatively good, the technical level of a color TV receiver is determined by these last two elements. Various kinds of dynamic adjustment techniques are used for improving picture quality. |
