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 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： 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.
摘要翻译： 3D到家的出现引发了许多挑战，超出了可用立体声对的基本显示。一个特别的挑战在于在终端级别渲染图形元素插入3D立体声内容的方式。如果图形被插入固定的深度，由于可能与周围3D视频的冲突，可能会发生视觉不适。本发明引入一种方法，其目的在于通过确保图形元素始终被感知在与观看者相距较短的距离处，从而消除深度冲突。该方法在于其能够在消费者设备上移植的能力，更确切地说，本发明描述了在差异估计水平上的适应以适应嵌入式系统中可用的有限处理能力。
