摘要： The invention relates to a method for combating the copying of source pictures by means of a camera while they are being displayed, for example using a camcorder in a movie theatre. To this end, it is known, in classical projection systems, to modulate by a carrier wave the brightness of some pixels of the pictures. The frequency of the carrier wave is usually constant and generally half the refresh frequency. The main problem with such systems is that once a pirate has figured out what the modulation frequency is, he can configure his camcorder shutter to filter out this frequency and bypass the anti-camcorder method. According to the invention, the frequency of the carrier is changed at least once throughout the displaying of the sequence pictures or the movie, to defeat all camcorders standards (PAL/NTSC) and shutter configurations.

摘要： This invention relates to a method to select, in an input image, pixels that can be watermarked by replacing their colour by a metameric colour. It comprises the following steps: correct the input image by applying a predetermined gamma law, convert the input image into a ‘metameric’ image in which the colours of the input image pixels are replaced by metameric colours, simulate the capture of the input image and of the metameric image by a camcorder in order to generate respectively a captured input image and a captured metameric image, determine, in a colour space and for each pixel of the input image, the distance between the colour of said pixel in the captured input image and in the captured metameric image, and select the pixels of the input image for which the distance is greater than a threshold. The invention also concerns a watermarking method based on metamerism.

摘要： To capture an image, the image sensing period of this image is subdivided into a plurality of successive illumination periods, and the value which is assigned to each pixel to capture the image is the sum of the integrals of intensity of illumination of this pixel over each of said successive illumination periods. According to the invention, this sum is weighted by an apodization function in order to emulate a mechanical shutter. Temporal aliasing issues and temporal ringing artifacts of digital imaging are prevented or at least limited.
