摘要： The invention relates to a display device using the DLP (Digital Light Processing) technology. This invention is in the field of digital cinema and content protection, where camcorder acquisition followed by immediate illegal distribution creates important revenue losses for content owners. According to the invention, the addressing of the display device is modified in order to introduce an anti-copy processing. The display device comprises modulation means (500) for modulating the colour or brightness of video data of video pictures received at a first rate and for outputting at a second rate modulated video data, said second rate being a multiple of the first rate, subfield coding means (501) for coding said modulated video data into subfield data, said subfield data being delivered at the second rate, and addressing means (502,503) for addressing the array with said subfield data at a third rate. Advantageously, the third rate is not a multiple of the first rate.

摘要： The advent of 3D to the home raises a number of challenges beyond the basic display of an available stereo pair. One particular challenge resides in the way to render a graphics element inserted on top of a 3D stereo content at the terminal level. Visual discomfort is likely to occur if graphics is inserted at a fixed depth because of a possible conflict with the surrounding 3D video. This invention introduces a method that aims at removing the depth conflict by ensuring that the graphics element is always perceived at a shorter distance from the viewer than the distance of the occluded video element. The method resides on its capability to being ported on a consumer device, more precisely, the invention describes adaptations at disparity estimation level to fit the limited processing power available in embedded systems.

摘要： What is proposed is a method for the color correction of digital image data generated by spectral absorption of white light in color filters of a first representation means. Color film material, in particular, is taken into consideration as the first representation means. For this purpose, firstly the primary color values R, G, B of the image data on the color film are detected. Said primary color values R, G, B are corrected in order to generate secondary color values R', G', B' which are related to a second representation means, for example a monitor. This correction involves taking account of the absorption of light in secondary densities of the colorants of the film material which form the color filters of the first representation means. For this purpose, a plurality' of absorption spectra are generated for different densities of the colorants. Finally, the spectral profile of the absorption spectra of the colorants influences the correction of the primary color values for generating the secondary color values. This follows the aim of achieving a maximum correspondence between the color representation with the first representation means and the color representation with the second representation means.

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 present invention relates to a method of improving the luminous efficiency of a sequential-colour matrix display, the display being driven using an addressing method of the pulse width modulation or PWM type. This method comprises, for each pixel of a subframe, the following steps:- comparison of the pixel colour value of the preceding subframe with a reference value so as to provide an overlap value depending on the period of overlap with the current subframe;- if the pixel colour value of the current subframe less the overlap value gives a positive value, a time offset is added to the pixel colour value of the current subframe;- if the pixel colour value of the current subframe less the overlap value gives a negative value, the pixel colour value of the current subframe is forced to be zero. The invention applies to LCOS or LCD displays.

摘要： Various implementations provide color images, including, for example, RGB images and/or HDR images. In one particular implementation, a color image is created using a first set of color values captured from multiple sensors. Multiple pixel locations of the color image have a color value for three colors that are captured from the multiple sensors. A lens assembly passes light to the multiple sensors. An HDR image is created using a second set of color values captured from the multiple sensors. Another implementation includes a lens assembly and multiple sensors arranged to receive light though the lens assembly. A first set of color values captured from the multiple sensors can be assembled to provide three color values for multiple pixel locations. A second set of color values captured from the multiple sensors can be interpolated to provide an HDR image.
