SYSTEM FOR DISPLAYING IMAGES WITH FOUR PRIMARY COLORS FROM VIDEO DATA BASED ON THREE PRIMARY COLORS.

摘要

The present invention relates to a video image display system capable of displaying video images with four primary colors from video data based on three primary colors. This system is particularly used to prevent copying of movies using camcorders in theaters. According to the invention, this system comprises a transformation circuit (100) of first video data (Rin, Vin, Bin) of an image pixel based on three color components, called first color components, in seconds. video data (Rout, Vout, Bout, Jout) based on said first three color components and an additional component (Jout), the value of the additional component of said second video data (Jout) being non-zero, and a display device (110; 111,112) for displaying said second video data. The transformation circuit (100) is composed of a plurality of transformation blocks for transforming the video data in real time.
