摘要： Method of displaying images on a projection screen in front of a place for an audience, by using different visually-equivalent metameric colors for different portions of images, and by simultaneously illuminating said place for the audience with perturbing infrared radiations and by simultaneously detecting any image capture device in the place for the audience, wherein: the different metameric colors that are visually-equivalent have different spectral wavelength distributions at least in the red region of wavelengths, detection is performed through the perturbing infrared radiations that are reflected by any object in the place for the audience. Such a system seems impossible to circumvent by pirates using camcorders.
