摘要： The present invention is in the field of Content protection, most particularly in cinema venues where camcorder acquisition followed by immediate illegal distribution creates important revenue losses for content owners. It is known that anti-camcorder systems using a color modulation can be circumvented by using low shutter speed in the camcorder. Today, the shutter speed is determined automatically by the camcorder as a function of the filmed video source. In automatic configurations, shutter speed self-adapts to either motion, or flicker detection, both of which taking into account brightness variations only. The proposed invention proposes a dual color/brightness modulation to defeat automatic shutter speed adjustment. For example, a color modulation at 50/60 Hz is carried out and a brightness modulation at a higher frequency 100/120 Hz is added to force the camcorder to work at a high shutter speed.
摘要翻译：本发明在内容保护领域，特别是在摄像机获取之后立即被非法分发的电影场所，对于内容所有者来说，对于收入损失是重要的。众所周知，使用彩色调制的防摄录机系统可以通过在摄像机中使用低快门速度来避开。今天，快照速度由摄像机自动确定为拍摄视频源的功能。在自动配置中，快门速度自适应运动或闪烁检测，这两者都仅考虑亮度变化。所提出的发明提出了一种双色/亮度调制来打败自动快门速度调节。例如，执行50/60Hz的色调，并且增加更高频率100/120Hz的亮度调制以迫使摄像机以高快门速度工作。

摘要： The invention discloses a new modulation scheme to prevent illegal copy in movie theaters. None of the existing modulation schemes make the right assumptions to modelize a camcorder device. In such classical schemes, camcorders are always considered as sampling devices without taking into account the effects of shutter speed. The shutter of the camcorder is classically compared to a low-pass filter. As a result, modulation effects can be easily removed by setting up shutter speed to low values (low cutoff frequency). The right mathematical modelization of the shutter effect shows that, in the spectral domain, the behavior of the camcorder is close to a cardinal sine function with a main lobe and sidelobes. Consequently, according to the invention, it is proposed to select a modulation frequency that not only generates visual artifacts once recorded by the camcorder under shutter-free conditions, but that can also generate artifacts despite low shutter speed settings by going through sidelobe of the shutter spectrum.
摘要翻译：本发明公开了一种防止电影院非法复制的新调制方案。现有的调制方案都没有制定正确的假设来建模摄像机设备。在这种经典方案中，摄像机总是被认为是采样设备，而不考虑快门速度的影响。摄像机的快门通常与低通滤波器相比较。结果，通过将快门速度设置为低值（低截止频率）可以容易地消除调制效果。快门效应的正确的数学模型化表明，在光谱域中，摄像机的行为接近具有主瓣和旁瓣的基本正弦函数。因此，根据本发明，提出了选择不仅在无快门条件下由摄像机记录的视觉伪影的调制频率，而且还可以通过经过快门的旁瓣来生成伪影，尽管低快门速度设置光谱。

摘要： A display device comprises revolving coloured wheels, so as to generate a periodic coloured beam, and an imager which modulates the coloured beam as a function of a received video signal. The coloured beam (8) takes successively at each period a plurality of primary colours in synchronism with the images generated by the imager for each primary colour. By adjustment of the relative position of the coloured wheels, it is possible to modify the hue of the primary colours so as to best match them to the received video signal.

摘要： A method for image processing of digital image pixels. Pixels are preferably filtered spatially and dithered, and the value for at least one colour component is bit reduced. The space freed by the bit reduction is used to allocate a look-up table selection bit that indicates which look-up table (LUT), from a plurality of small LUTs partitioned from a bigger LUT, should be used for the colour transform. The transformed pixels are then selected according to the used LUT, format converted and output. The invention, which also covers an apparatus and a pre-processing module, enables an apparatus with a LUT to be used both as a single full-rate LUT apparatus and as a lower-rate n smaller LUT apparatus.

摘要： The present invention relates to an image processing apparatus and device intended to temporally modulate a sequence of source images with a modulation image comprising at least one anti-copy pattern. According to the invention, it is proposed that the modulation image be generated on the basis of the source image to be modulated in such a way as to place the patterns at locations of the image that may hinder the person watching an illicit copy of the video sequence (filmed for example by a camcorder). The modulation image is for example an image of the secondary contours of the image. The patterns are therefore placed in the low-gradient zones of the source image.

摘要： A method of generation of computer images of a three-dimensional scene constituted by a set of facets, viewed from a point of observation along a viewing axis. The facets are projected on the surface of a sphere whose center is the point of observation of the scene and wherein the surface of the sphere is divided in a special way into elementary surfaces, each corresponding to a pixel on the spherical surface, in such a manner that the orthogonal projections of the elementary surfaces on a reference plane passing through the point of observation and perpendicular to the viewing axis of the scene all have same value. An application is the generation of visibility or distance images. Another application is radiosity.

摘要： Before the transmission of the source color values of the images of each group Gk of images of this sequence, a partial color transform LUT related to this group Gk is generated, then transmitted, —and, a resultant color transform LUT related to said group Gk is reconstructed by combining the transmitted partial color transform look up table of this group Gk with, if any, all the other partial color transform look up tables that have been previously transmitted, —then each images of said group are color transformed using this LUT. The invention allows a good precision of color transformation with a limited bandwidth.
