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： 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： 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。
