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 invention proposes a novel technique for coding video for a plasma display panel, which aims to improve the use of rotating code. The method forming the subject of the invention carries out a coding of the highest grey level V1 over the entirety of the subscans while favouring the subscans whose illumination time is the lowest. The coding of the lowest grey level V2 is achieved using the common value COMMAX which results from the coding of the value V1 if the specific value SPEMAX is greater than the difference D of the grey levels. If SPEMAX is greater than the difference D, then the coding of the common value COMMIN corresponds to the lowest value V2.

摘要： The present invention relates to a method of compensating for the differences in persistence of the phosphors in an image display screen consisting of cells arranged in lines and in columns, several adjacent cells being covered with different phosphors in order to form a pixel, the cells of one pixel being put either into an “off” state or into an “on” state for a time within one frame period depending on the grey level to be displayed. According to the method, at the pixel, the transitions between a first grey level and an adjacent second grey level are detected and if the transition is greater than a threshold the state of the cell covered with a persistent phosphor is forced to the second grey level before the end of the frame period. The invention applies especially to plasma panels.

摘要： The invention consists in a method for generation of 3D image signals. A graphic object is inserted in said image at a determined depth. A frame of a determined thickness surrounds the object to be inserted. A transition zone is defined by the frame around the inserted graphic object. The depths of image elements of the transition zone vary progressively from the external edge to the internal edge of the frame of the graphic object to be inserted. The present invention also relates to a device for generation of said display signals.

摘要： The invention relates to a method of processing source images which is intended to combat their copying by a camcorder or a camera during their display, for example in a cinema hall. The source image sequence represents a scene. According to the invention, the method comprises the following steps: detection, in the said scene, of at least one zone corresponding to an object of the scene, selection of the entirety of the pixels of the said at least one zone in at least one source image of the sequence; and processing of the said at least one source image to modify the color of the selected pixels or the spectral composition of the light emitted by the selected pixels so that the perceived color of the selected pixels is unchanged in the processed source image with respect to the source image.

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 artifacts 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 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.
