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.

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： An image projection system has an illumination system for moving bands of different colored light over the light valve. The image projection system identifies the illumination color of each row of pixels of this light valve, manages the video data of the images to control the writing of the pixels, synchronizes the video data sent to each row of pixels according to the identified illumination color of the row. At least one photosensitive sensor is level with certain rows of pixels of the light valve, is incorporated in the substrate and is designed to identify in real time the illumination color of each row.

摘要： A colour quality control device adapted for use in a system for colour correction of an image to be reproduced on at least one reproduction device that is calibrated by a reproduction forward transform. The system also comprises a colour correction device adapted to correct at least one colour in the image. The colour quality control device comprises a false contour detection unit that uses information from the reproduction forward transform to decide if a contour in the image is a false contour introduced by the transform. This facilitates the operator's work during colour correction. A system and a method are also provided.
