    摘要： This method comprises the following steps: displaying the different intermediate colour versions, from a visual comparison between displayed versions, selecting a second set, determining an intermediate colour transform able to transform an original version of said source image into each of said selected intermediate colour versions by a comparison between the original version of said source image with the selected intermediate colour version, building a final colour transform by combining each of the determined intermediate colour transforms, generating the final colour version by applying the built final colour transform to the original version of said source image.

    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.

    摘要： A method for characterizing a color reproduction device. A first output color measure responding to a first reference input color value is measured under normal measurement conditions. The measurement conditions are modified and a second output color measure responding to the first reference input color value is measured under the modified measurement conditions. A transformation rule, enabling transformation between the second output color measure and the first output color measure, is calculated from the first color value and the second color value. A first set of output color measures responding to a set of input color values is measured under modified measurement conditions, and the first set of output color measures is converted, using the transformation rule, to a second set of output color measures. A system and a control device are also provided.

    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： The present invention relates to a device and a method for displaying images. To combat the copying of images by a camcorder in a cinema auditorium, modulating the luminance of the pixels of a pattern around the value to be displayed to a high frequency which makes the pattern invisible to the human eye but which generates artifacts on the sequence filmed by the camcorder is known. According to the invention, it is proposed to temporally modulate the pattern only in the fixed areas (background or indoor scenes) or, where appropriate, the areas with weak movements. Thus, rather than degrading the image in the areas with movement by applying to them the temporal modulation processing, a decision is taken not to temporally modulate the pattern in these critical areas.

    摘要翻译： 本发明涉及一种用于显示图像的装置和方法。 为了对抗摄像机在电影礼堂中复制图像，将要显示的值周围的图案的像素的亮度调制到高频，这使得图案对人眼不可见，但是在拍摄的顺序上产生伪影 由摄像机知道。 根据本发明，提出仅在固定区域（背景或室内场景）或适当的情况下对运动较弱的区域进行时间调制模式。 因此，不是通过向他们施加时间调制处理来降低具有移动的区域中的图像，而是决定不在时间上调制这些关键区域中的图案。
