摘要： The present invention relates to a method for displaying a video image on a digital display device during a video frame comprising at least two distinct time segments for displaying a grey level. The cells of the device are able to take selectively an on state or an off state. The cells are able moreover to change state several times during a video frame. According to the invention, the cells change state at most once during each time segment of the video frame. The invention makes it possible to attenuate or suppress disturbances related to the temporal integration and to the sequential displaying of the R, G, B components of the video image.

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.

摘要： The present invention relates to a device for digital display of a video image using time-division modulation. This device is intended to display a video image during a video frame comprising a plurality of consecutive subfields distributed within at least two separate identical time segments. According to the invention, the pixels of the video image change state at most once during each time segment and the video image to be displayed is saved in the image memory in the form of information identifying, for each subfield, the pixels changing state.

摘要： The invention provides a solution for reducing the bit rate of the image memory which stores the binary images displayed on a digital display device. At least one binary image 16c is stored per group of at least two pixels of like binary value. Means duplicate the pixels of the image stored per group of pixels during display on a digital display element.

摘要： The present invention relates to a method of processing a video image sequence in a liquid crystal display panel and to a device for implementing this method. According to one embodiment of the invention, at least one motion-compensated image is generated for each group of m consecutive images of the sequence, m being greater or equal to 2, in order to obtain a group of n consecutive images, with n>m. Said group of n consecutive images replaces the group of m consecutive images into the sequence. Next, for each pixel having in a current image of the new sequence a current grey level and in the next image a different target grey level, an intercalary grey level is calculated which is higher or lower than said target grey level depending on whether said target grey level is respectively higher or lower than the current grey level of the pixel. Next, in the current image, the current grey level of the pixels is replaced with said calculated intercalary level. This method makes it possible to correct the blurring effects due to the mode of display and to the high response time of the LCD panel.

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 method comprises the following steps: detection of the static areas in the current picture, calculation of a histogram for the non-static areas of the current picture calculation of the difference between the histogram of a current picture and the histogram of at least one preceding picture, declaration of scene change if the difference is greater than a predetermined threshold. The applications related to video processing using picture movement such as up-conversion of video pace, reduction of motion compensated noise.
