Method and device for displaying a sequence of images |
摘要 |
The present invention relates to a method and a device for displaying a sequence of images that makes it possible to prevent any unauthorized copying of the latter. It applies to any type of digital display device comprising a matrix of light cells comprising a number of rows and/or columns of cells greater than the number of rows and/or of columns of pixels of the images to be displayed. According to the invention, to disrupt the illegal copying of sequences of images in cinema auditoria, it is proposed to modify the frame frequency of the displayed images by varying the number of rows and/or columns of cells addressed with a black level for at least two images of the sequence.
