摘要： To capture an image, the image sensing period of this image is subdivided into a plurality of successive illumination periods, and the value which is assigned to each pixel to capture the image is the sum of the integrals of intensity of illumination of this pixel over each of said successive illumination periods. According to the invention, this sum is weighted by an apodization function in order to emulate a mechanical shutter. Temporal aliasing issues and temporal ringing artifacts of digital imaging are prevented or at least limited.

摘要： The invention concerns a method for processing a sequence of source pictures to generate artifacts due to aliasing when these source pictures are captured by a video capturing device. This method comprises a first time modulation step for modulating temporally at a first modulation frequency the brightness of pixels of each picture of the sequence around a brightness to be displayed for said picture. According to an important feature of the invention, the method further comprises a second time modulation step for modulating temporally at a second modulation frequency different from the first modulation frequency the brightness of pixels of each picture of the sequence around a brightness value to be displayed for said picture, the first and second modulation frequencies being determined in order not to be visible to the human eye and contributing to generate aliasing artifact at a predetermined aliasing frequency.

摘要： The present invention is situated within the frame or video processing domain and more particularly in the domain of video interpolation. It relates to a device for generating an interpolated frame from source frames temporarily surrounding it. This device comprises motion estimation means, motion compensated interpolation means, linear interpolation means, means for mixing the frame produced by the motion compensated interpolation means with the frame produced by the linear interpolation means. According to the invention, the mixing coefficients assigned to these two frames depend on the displaced frame difference and/or the frame difference between the source frames surrounding this interpolated frame and/or estimated motion vectors.

摘要： The invention deals with the large area flicker effect reduction in display devices like plasma display panels, in which the light output is controlled by small pulses over a whole frame period and the amount of small pulses determine the brightness of the light output. The invention proposes an adaptation of the known principle of sub-field grouping for large area flicker reduction for the specific sub-field coding process called incremental sub-field coding, in which only those sub-field code words are taken for display driving having the characteristic that there is never a sub-field inactivated between two activated sub-fields or never a sub-field is activated between two inactivated sub-fields.For this specific sub-field coding it is proposed to make the sub-field grouping in a simple manner, where all the odd sub-fields are grouped together in one group (G1) and all the even sub-fields are grouped together in a second group (G2). Despite the fact that some luminance differences are present in the groups it has been proved, that this sub-field grouping leads to a very efficient large area flicker reduction because of its complementary behaviour to the required dithering technique.
摘要翻译：本发明涉及诸如等离子体显示面板的显示装置中的大面积闪烁效应的降低，其中光输出在整个帧周期内由小脉冲控制，并且小脉冲的量决定光输出的亮度。本发明提出了对于称为增量子场编码的特定子场编码处理的用于大面积闪烁减少的子场分组的已知原理的适应，其中仅采用那些子字段代码字用于具有在两个未激活的子字段之间激活两个激活的子字段之间永远不会被激活的子字段或从不会有一个子字段的特征。对于这种特定的子场编码，提出以简单的方式进行子场分组，其中所有奇数子场被分组在一个组（G1）中，并且所有偶数子场被分组在一起第二组（G2）。尽管已经证明在组中存在一些亮度差异的事实，但是由于其对所需的抖动技术的补充行为，该子场分组导致非常有效的大面积闪烁降低。

摘要： The present invention relates to a method of displaying video images on a plasma display panel. The invention is applicable in plasma display panels. According to the invention, in order to achieve contouring movement compensation, the subscans are divided into two symmetrical groups of subscans. Moreover, the movement of the video image to be displayed with respect to the preceding video image is estimated so as to generate a movement vector for each pixel of the video image. Finally, for each pixel of the video image, the subscans of the second group are displaced by an amount proportional to the estimated movement vector.

摘要： The invention corrects display faults due to the disparities between the phosphors of a display device. The correction is carried out by image processing. The invention provides a method for displaying a sequence of video images on a phosphor device comprising at least two types of phosphors together with the device comprising the means for implementing this method. The correction is carried out by computing an intermediate image between two successive images, then by displaying one of the two successive images on one type of phosphor and by simultaneously displaying the intermediate image on another type of phosphor.

摘要： The present invention relates to an apparatus and a device for displaying images. It is known to inlay a pattern of watermark type into the sequence of images to be displayed so as to combat the copying of images by picture-taking. This inlaying consists in modulating the intensity of the pixels of the pattern about the value to be displayed at a high frequency which renders the pattern invisible to the human eye but which generates artefacts on the sequence filmed by the camcorder. This technique poses problems when the sequence of images to be displayed comprises scenes in motion. The pattern appears since the integration carried out by the eye at the moment of display of the images is not correct. According to the invention, it is proposed that the patterns to be inlayed be motion compensated.
