摘要： The driving of an active matrix organic light emitting display (AMOLED) shall be improved. A pulsing grayscale rendition shall be combined with an improved motion rendition when driving the AMOLED with analog signals. Therefore, there is provided a data signal which is applied to each cell of the AMOLED for displaying a first grayscale level of a pixel of the image during a first group of sub-frames (SFO to SF5)for displaying at least a second grayscale level of a pixel of the image during at least a second group of sub-frames(SF'O to SF'5). The first group of sub-frames (SFO to SF5) and the at least second group of sub-frames (SF'O to SF'5) are constituting a video frame N. Each group of sub-frames is divided into a plurality of sub-frames. Each, the first group of sub-frames and the second group of sub-frames is belonging to a separate complete image of the display (AMOLED). The data signal of a cell comprises plural independent elementary data signals wherein each of the elementary data signals is applied to the cell during a sub-frame and the grayscale level displayed by the cell during the respective group of sub-frames depends on the amplitude of the elementary data signals and the duration of the sub-frames. With this concept, a flicker-free and a very high level of motion rendition can be offered.

摘要： The gravity centred (GCC) coding shall be improved with respect to false contour effect disturbances on plasma display panels for example. Therefore, there is provided a GCC code and a motion information of a picture or a part of a picture. Furthermore, there is provided at least one sub-set code of the GCC code. The video data are coded with the GCC code or the at least one sub-set code depending on the motion information. Thus, it is possible to reduce the number of coding levels if the motion increases. A further improvement can be obtained by using texture information for selecting the GCC code.

摘要： The invention concerns an automatic format decision related to the useful picture content part of a picture signal (INP) that may contain black bars and/or subtitles in the active picture. The processing includes:
Determining (HLPF, BLADJ, GRDHT, BBI) whether or not black bars are present in the active picture by analysing the presence of significant horizontal borders, and where said borders are located;
Determining (LCI) whether or not a luminous area located vertically in the middle of the useful picture content is present.
It is decided (FDEC) that the format of a current useful picture content part is not different from the format of a previous useful picture content part if the number (B1CNT, B2CNT) of luminance pixel values having a 'black' level exceeds a count number threshold.
It is decided (FDEC) that the current format is different if there are not too many candidate black bar borders, and the number (B1CNT, B2CNT) of luminance pixel values having a 'black' level exceeds the count number threshold, and there is a sufficient number (LGHTCNT) of bright pixel values in the middle area.摘要翻译： 本发明涉及与有效图像中可能包含黑条和/或字幕的图像信号（INP）的有用图像内容部分有关的自动格式决定。 该处理包括：通过分析显着的水平边界的存在以及所述边界所在的位置来确定活动图片中黑条是否存在（HLPF，BLADJ，GRDHT，BBI）; 确定（LCI）是否存在垂直于有用图像内容中间的发光区域。 如果具有“黑色”的亮度像素值的数量（B1CNT，B2CNT），则决定（FDEC）当前有用图像内容部分的格式与先前有用图像内容部分的格式不同， 级别超过计数值阈值。 如果没有太多的候选黑条边界，则决定（FDEC）当前格式是不同的，并且具有“黑”电平的亮度像素值的数量（B1CNT，B2CNT）超过计数数阈值 ，并且在中间区域中存在足够数量（LGHTCNT）的亮像素值。

摘要： The invention relates to a method for processing video data to be displayed on a display device having a plurality of luminous elements corresponding to the pixels of a video picture, wherein an error diffusion step is applied to at least a part of said video data to refine the grey scale portrayal of said video picture, said error diffusion step comprising, for each current pixel of said part of video picture, a step of truncating the value of the corresponding video data and a step of diffusing the truncation error to at least one neighboring pixel. According to the invention, a noise is inserted on the error before and/or after its diffusion to the neighbouring cells. Owing to this principle no static pattern should be visible, improving the overall picture quality.

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 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.
