20090021458 | High contrast liquid crystal display - A projection system including a first imager that is an organic light emitting diode (OLED) imager configured to modulate a light band on a pixel-by-pixel basis proportional to gray scale values provided for each pixel of the image to provide a first output matrix and a second imager positioned and configured to receive the first output matrix of modulated pixels of light from the first imager on a pixel-by-pixel basis proportional to a second gray scale value provided for each pixel of the image is disclosed. | 01-22-2009 |
20090072711 | Organic light-emitting diode (oled) with improved light extraction and corresponding display unit - The invention relates to an organic light-emitting diode comprising on a substrate, from the rear face to the front face, at least one so-called rear electrode of a first type surmounted by an organic light-emitting layer, itself surmounted by at least one so-called front electrode of a second type, the organic light-emitting layer producing light when holes and electrons are injected into it by a current flowing through the electrodes, the types corresponding to an anode and a cathode, at least one of the electrodes being substantially transparent for the produced light in order to allow it to escape through one of the faces of said diode, referred to as the exit face. According to the invention, said substantially transparent electrode comprises at least one transparent extraction zone and at least one reflective zone adapted to return the produced light through the light-emitting layer, and said diode also comprises reflector means which are arranged on the opposite side of said substantially transparent electrode from the organic light-emitting layer and are adapted to return the produced light to said substantially transparent electrode through the light-emitting layer. The diode may be configured by embossing, and various embodiments are described. | 03-19-2009 |

20120320160 | DEVICE FOR ESTIMATING THE DEPTH OF ELEMENTS OF A 3D SCENE - Device comprising: | 12-20-2012 |
20130155194 | ANAGYLPHIC STEREOSCOPIC IMAGE CAPTURE DEVICE - The device comprises an aperture stop disc divided into a plurality of mutually exclusive filtering segments comprising a first, a second and a third filtering segment; the third filtering segment is adapted to pass a third portion of the spectrum which is included in the portion of the spectrum passing the first and second filtering segments. | 06-20-2013 |
20130342642 | METHOD AND DEVICE FOR TEMPORAL FILTERING OF DISPARITY MAPS - The invention consists in a method of and a device for temporal filtering of disparity maps of n different frames, each map indicating the disparity of pixels of 3D images comprising the steps of marking the stationary pixels and the non stationary pixels and implementing temporal filter for stationary pixels, detecting limitations for temporal filtering corresponding to a variation of moving pixels above a determined threshold value and automatically de-activating the temporal filters as response to the detected limitations for temporal filtering. | 12-26-2013 |
20150117757 | METHOD FOR PROCESSING AT LEAST ONE DISPARITY MAP, CORRESPONDING ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT - In one embodiment, it is proposed a method for processing at least one disparity map associated to at least one left view and one right view of stereovision images. Such method is remarkable in that it comprises determining at least one modified disparity map that comprises, for a given pixel or group of pixels, a modified disparity value determined in function of disparity values of the at least one disparity map associated to pixels that belong to a neighborhood of the given pixel or group of pixels, said disparity values being weighted in function of a value obtained from the at least one disparity map and at least one other disparity map. | 04-30-2015 |
