摘要： The invention relates to a method and device for processing video images aimed at compensating for the defects of display devices. According to the invention, the method is characterized in that it comprises the following steps: correction of a video signal by a specific gamma law associated with a first component from among said horizontal and vertical components of said video signal, first video processing acting on said first component of the corrected video signal, application, to the video signal processed, of an intermediate law effecting the transfer from a space which is linear with respect to the first component to a space which is linear with respect to the other of said components, called the second component, second video processing acting on the second component of the video signal emanating from the previous step, and correction of the video signal processed by a specific inverse gamma law associated with the second component.

摘要： The present invention relates to a processing device of a sequence of video images intended to be displayed by a digital cinema projection system, a projection system for the digital cinema and a video signal designed to be used by such a system. The use of an anti-camcorder method against copying films is generally carried out entirely in the digital cinema projection system. However, this method requires complex video processing and costly means in the projection system. According to the invention, it is proposed to carry out part of the video processing at the level of the post-production of the video sequence and to save the result of this “pre-processing” in the form of metadata. The remaining part of the video processing is carried out from this metadata in the video projection system.

摘要： The present invention relates to a device and a method for displaying images. To combat the copying of images by a camcorder in a cinema auditorium, modulating the luminance of the pixels of a pattern around the value to be displayed to a high frequency which makes the pattern invisible to the human eye but which generates artefacts on the sequence filmed by the camcorder is known. According to the invention, it is proposed to temporally modulate the pattern only in the fixed areas (background or indoor scenes) or, where appropriate, the areas with weak movements. Thus, rather than degrading the image in the areas with movement by applying to them the temporal modulation processing, a decision is taken not to temporally modulate the pattern in these critical areas.

摘要： The present invention relates to a method of improving the luminous efficiency of a sequential-colour matrix display, the display being driven using an addressing method of the pulse width modulation (PWM) type. This method comprises, for each pixel of a subframe, the following steps: comparison of the pixel colour value of the preceding subframe with a reference value so as to provide an overlap value depending on the period of overlap with the current subframe; if the pixel color value of the current subframe less the overlap value gives a positive value, a time offset is added to the pixel color value of the current subframe; if the pixel color value of the current subframe less the overlap value gives negative value, the pixel color value of the current subframe is forced to be zero. The invention applies to LCOS or LCD displays.

摘要： The invention relates to a method and a device for processing a mosaic of noisy source images exhibiting overlap zones where at least two of the source images are superimposed. According to the invention, the method comprises a step of generating a random noise (35) in the overlap zones so as to compensate at least partially for the deviation in noise between the overlap zones and the zones where the source images are not superimposed, called non-overlap zones.

摘要： The present invention relates to a coding method intended to improve the performance of GCC coding based on the temporal centre of gravity of displayed video codes. According to the invention, the number of video levels that can be selected in order to implement the GCC coding is increased by increasing the number of subfields in the video level display frame. This increase in the number of subfields is made possible by simultaneously addressing the cells of at least two adjacent rows of the PDP during at least two subfields of the video image display frame.

摘要： The present invention relates to a method for enhancing the contours in a video image. It applies more particularly to cathode-ray tube digital televisions. The method of the invention consists in detecting the contours of the images, in oversampling the image signal to be provided to the tube, in increasing the video level of at least one of the samples of the pixels corresponding to a contour while preserving the luminous energy of each of the pixels, then in converting the modified signal into an analogue signal intended for the cathode-ray tube. The contours then appear finer and more visible on the screen of the television. Preferably, the modification of the sampled signal consists in reducing the number of samples of the pixel corresponding to a contour and in redistributing the video level of the samples removed to the other samples of the pixel of the contour.
摘要翻译：本发明涉及一种用于增强视频图像中的轮廓的方法。更适用于阴极射线管数字电视。本发明的方法在于检测图像的轮廓，在对要提供给管的图像信号进行过采样时，在增加对应于轮廓的像素的至少一个样本的视频电平的同时保持光能，然后将修改的信号转换成用于阴极射线管的模拟信号。然后，轮廓在电视机的屏幕上显得更细，更可见。优选地，采样信号的修改在于减少对应于轮廓的像素的样本数量，并且将所移除的样本的视频电平重新分配到轮廓的像素的其他样本。
