METHOD AND APPARATUS FOR PROCESSING VIDEO PICTURES |
摘要 |
The invention relates to a method for processing data of video pictures for displaying the pictures on a display device like a plasma display panel. For having a good video picture quality one key characteristic is to have a good response fidelity of the plasma cells. This is not always the case since the fidelity of each cell depends on the excitation 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 excitation 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 excitation in the neighbouring cell in order to maintain the cascade effect. <IMAGE> |
