Abstract: 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 artefacts 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.

The systems and methods convert relative image data produced by a camera to absolute light intensity data using a compensation factor. The compensation factor accommodates for hardware and specific imaging conditions in the imaging system that variably affect camera output.

Upon subsequent imaging with the set of imaging conditions, the corresponding compensation factor is called from memory and applied to the camera output. A compensation factor may be determined and stored for each hardware state and imaging condition available to the imaging system.
