    摘要: A method and system for reducing pixel interdependence errors in an imager caused by adjacent pixel drive interdependence. The method compares a first brightness control level for a first pixel to a brightness control level for at least one adjacent pixel of the imager by pixel delay elements (102 and 104). Based on the results of the comparing step, estimator (106) estimate the pixel interdependence effect of the outer pixels on the adjacent piyel and the system modifies the first brightness control level for the first pixel to compensate for the pixel interdependence effect. The output of clipper (116), a modified brightness control level is determined for the first pixel that results in an actual brightness for the first pixel in the presence of pixel interdependence effect, which more closely approximates the actual brightness that would result from the un-modified first brightness control level in the absence of pixel interdependence effect.

    摘要: The invention concerns a clock recovery method in digital signal sampling, the clock being generated from a phase-locking loop or PLL (1) which multiplies a given frequency by a whole number. Said method comprises a step which consists in comparing the relative position of the signals with respect to the clock so as to determine whether a selected type of the clock transitions is in phase with the same type of signal transitions by: producing (6) over a clock period several zones, one zone corresponding to the selected type of transitions; analysing (5) the signal transitions relatively to the clock uplink or downlink transitions; cumulating in the corresponding zone the analysis results; determining (10, 9) on the basis of the accumulation whether the sampling clock frequency and/or phase needs to be modified or not. The invention is applicable to signals derived from graphics cards.

    摘要: The invention concerns a method for displaying a video image on a digital display device during a video raster comprising at least two separate time segments to display a grey level. The cells of the device can selectively adopt an on-state or an off-state. Additionally, the cells can change states several time during a video raster. The invention is characterized in that the cells change state not more than once during each video raster time segment. The invention enables attenuation or elimination of perturbations related to temporal integration and sequential display of the R, G, B components of the video image.

    摘要: The invention concerns a device for generating mutual photometric effects. The invention concerns also a server for delivering photometric parameters for generating mutual photometric effects and a system including such a device and such a server. According to the invention the device (1) comprises - means for receiving and demultiplexing said visual data sets and photometric parameters respectively associated with said data sets, - means for defining said mutual photometric effects to be generated for these photometric parameters, - composition and rendering means for positioning said visual data sets in said common support space and applying said effects defined for said photometric parameters from at least one of said visual data sets to at least one other of said visual data sets so that at least one visual data set influences one other visual data set in said common support space.
