摘要： A plasma display panel is a pure linear display and does not provide a nonlinear gamma behaviour 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 reas. 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.
摘要翻译：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，使得人造伽马功能必须以数字形式应用于信号。该伽马函数增加了暗区域中的量化步长，而在发光区域中量化步长将会减小。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，过滤将是最大的，并且当区域的亮度增加时，其功效将自动降低。

摘要： The invention relates to a method for processing data of video pictures for displaying the pictures on a display de-vice like a plasma display panel. For having a good video picture quality one key characteristic is to have a good re-sponse fidelity of the plasma cells. This is not always the case since the fidelity of each cell depends on the excita-tion of the neighboring cells. The so-called neighborhood effect can reduce the vertical sharpness in the picture. The invention solves this problem with a vertical peaking process in which it is analysed whether the cell excitation in an activated sub-field after an inactivated sub-field for a current pixel gets support by a parallel cascaded cell ex-citation of a neighbouring cell. If no such support is found, the sub-field code word for the current pixel is modified in such a manner that the entry in the sub-field code word for the inactivated sub-field is replaced by an entry for an activated sub-field. In this way it is assured that cell excitation in the activated sub-fields for the current pixel is supported by a parallel cascaded cell exci-tation in the neighbouring cell in order to maintain the cascade effect.
摘要翻译：本发明涉及一种用于处理视频图像数据的方法，用于在诸如等离子体显示面板的显示装置上显示图像。为了具有良好的视频图像质量，一个关键特征是具有良好的等离子体单元的重新保真度。这并不总是这样，因为每个单元的保真度取决于相邻单元的激励。所谓的邻域效应可以降低画面的垂直锐度。本发明通过垂直峰值处理来解决这个问题，其中分析当前像素的非激活子场之后的激活子场中的单元激励是否由相邻单元的并联级联单元格引用支持。如果没有找到这样的支持，则以这样的方式修改当前像素的子字段代码字，使得非激活子字段的子字段代码字中的条目被激活的子字段的条目替换。以这种方式，确保当前像素的激活的子场中的单元激励由相邻单元中的并联级联单元偏移支持，以便保持级联效应。

摘要： The number of available sub-fields for stereoscopic displaying on plasma display panels is not high enough to insure a good grey-scale portrayal as well as a good false contour behaviour. Thus, the number of sub-fields is artificially increased by commonly addressing the sub-fields of two or more pixel lines so that the addressing time of the panel may be decreased for each sub-field.
摘要翻译：在等离子体显示面板上用于立体显示的可用子场的数量不足以确保良好的灰度图形以及良好的假轮廓行为。因此，通过共同寻址两个或更多个像素线的子场来人为地增加子场的数量，使得可以为每个子场减小面板的寻址时间。

摘要： The visible pattern of classical matrix dithering in case of applications with moving pictures and static pictures shall be suppressed more effectively. Therefore, it is proposed to change a dithering pattern in the dithering block (12) nonperiodically. This can be effected by a random generator (13) which may be activated by a motion detector (14). The motion detector (14) enables to individually alternate the dithering function depending on moving or static pictures.

摘要： Response fidelity problems appear for some specific video levels at PDP borders. The reason is that some cells at the border of the PDP panel are not completely closed and pollute when switched ON neighbouring cells being OFF. Therefore, it is suggested to encode the video levels in the border area in a specific way. Especially, for critical subfields within the code it is forbidden to insert a binary 0 between two binary 1. Thus, the neighbourhood of critical sub-fields being ON and OFF is avoided. Preferably, the specific border coding is performed under the control of an average power management (2) and codewords being not used are recreated by dithering (6).

摘要： CMOS image sensors are usually suffering from fixed pattern noise and random defect pixels. However, for economical reasons and in order to increase the manufacturing yield, some random defective pixels are usually accepted even for professional devices. In this case, the defect pixels are usually corrected by signal processing. A processing device (15) for correcting of at least one defect pixel value of an image sensor unit is proposed, the image sensor unit comprising at least a first and a second pixel array (1, 2, 3), wherein the image sensor unit is embodied to project the same image onto each pixel array (1, 2, 3), the processing device (15) comprising at least a first and a second input channel (11, 12, 13) for receiving pixel values of the first and the second pixel array, respectively, wherein the processing device (15) is operable to exchange the defect pixel value by a corrected pixel value, wherein the corrected pixel value is estimated by evaluating the values of neighbouring pixels of the defect pixel of the same pixel array, wherein the corrected pixel value is estimated by evaluating values of a corresponding pixel and its neighbouring pixels of the second pixel array at the same location as the defect pixel of the first pixel array in respect to the projected image.
