    • 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.
    • 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。
