    摘要: The invention relates to a method and system for validating the graphical generation of symbols to display, comprising a graphical generation of symbols to display to form a video stream comprising a plurality of rasters, comprising a pixel generation, with the attribution of at least one associated symbol attribute for each pixel contributing to one of said symbols. The method comprises, for at least one raster of said video stream: obtaining at least one reference symbol attribute associated with at least one symbol to be monitored; identifying pixels having the reference symbol attribute(s), during a scan of the pixels of said raster in a predetermined course direction, these pixels contributing to said at least one symbol to be monitored, and calculating associated characteristic information; validating the display of the symbol(s) to be monitored based on the calculated characteristic information and of source information associated with said symbols to display.

    摘要: The general field of the invention is that of monochromatic stereoscopic image projectors including two light sources that illuminate two imagers, the radiation of the two light sources having a spectral distribution centred on a central wavelength, the first imager and the second imager being connected to a generator of stereoscopic image pairs. The image projector includes a dichroic separating filter that transmits the portion of the spectrum below the central wavelength and that reflects the portion of the spectrum above this central wavelength. The first light source and the second light source are arranged symmetrically on either side of the dichroic separating filter. The image projector operates cyclically, each cycle including two alternations. Each alternation consists in changing the emission source and in switching to the two displays the left and right images emitted by the generator of image pairs.

    摘要: Visual display systems are described having means for generating stereoscopic images, a device for visual display of said stereoscopic images having a projector and a semitransparent screen; and a pair of stereoscopic spectacles. The projector according to the invention has an imager and an interference filter, the spectral transmission of which has at least one transmission band of determined width centerd around a wavelength, said wavelength being dependent on the incidence of the light on said interference filter. The projector has means allowing the angular position of the filter to be varied between two determined positions so as to transmit, according to the position, either a first spectral band or a second spectral band. The pair of stereoscopic spectacles has a first lens transmitting the first spectral band and blocking the second spectral band and a second lens providing the opposite function.

    摘要: The general field of the invention is that of the methods of processing an initial digital image IIN(p) made up of pixels (p). The method according to the invention comprises the following successive steps: Step 1: calculating the logarithm of the initial image in order to obtain a first intermediate image Log(IIN(p)); Step 2: filtering said first intermediate image using a low-frequency filter in order to obtain a second intermediate image BF(p); Step 3: determining the value of the minimum intensity and the value of the maximum intensity in the low-frequency image; Step 4: calculating a third intermediate image Log(IOUT(p)) using the following linear combination: Log(IOUT(p))=[Log(IIN(p)−BF(p)]·[K1·BF(p)+K2]+K3·BF(p)+K4 K1, K2, K3 and K4 being constants; Step 5: calculating the final image IOUT(p) by applying the exponential function to the third intermediate image.
