Abstract: A plasma display panel is a pure linear display and does not provide a non-linear gamma behavior like a CRT so that an artificial gamma function has to be applied to the signal in digital form. This gamma function increases the quantization steps in the dark areas whereas the quantization steps will be reduced in the luminous areas. The basic idea is to apply an adaptive noise filtering after the gammatization process. The adaptive filtering is a specific filtering which is adapted to the gammatization quantization noise. In other words, the filtering will be maximum for dark areas and its efficacy will be automatically decreased when the luminance of the area is increasing.

Abstract translation: 等离子体显示面板是纯线性显示器，并且不提供诸如CRT的非线性伽马行为，使得必须以数字形式将人造伽马功能应用于信号。 该伽马函数增加了暗区域中的量化步长，而在发光区域中的量化步长将会降低。 基本思想是在恶意化过程之后应用自适应噪声滤波。 自适应滤波是适应于伽玛化量化噪声的特定滤波。 换句话说，对于暗区域，滤波将是最大的，并且当区域的亮度增加时，其功效将自动降低。
