    摘要: A device for the presentation of documents, which includes a back element (3; 13; 17) and a frame (2) capable of surrounding the back element (3; 13; 17). The latter includes one or more fixing elements (9; 10), each comprising a part (20) capable of deforming elastically. When the device (1) is in the closed state, each of the elements applies a clamping force to the frame (2), causing the document (8) to be clamped.

    摘要: The disclosure relates to a device and to a method for noise reduction of a video signal. The device is comprised of the following components. A motion-compensated interpolation means, a recursive filter intended to receive the output of the recursive filter motion-compensated by the interpolation means at a first input, and the video signal at a second input; means for calculating the difference between the video signal and the output of the recursive filter motion-compensated by the interpolation means; wherein the device includes means for providing the first input of the recursive filter either with the video signal if the difference is greater than a predetermined noise level threshold, or the motion-compensated output of the recursive filter, if the difference is less than the said predetermined noise level threshold.
