As an imaging prevention method for interfering unauthorized imaging of a number of visual images projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector devices. According to the method, infrared light may be directly incident into an imaging apparatus of a person conducting an unauthorized copying act so as to adversely affect the unauthorized copying.

Imaging prevention method and system

As an imaging prevention method for interfering with the unauthorized imaging and recording of a visual image projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector means disposed at a rear side of the screen. According to the method, an amount of the infrared light is directed to be incident into an imaging apparatus attempting to record an image from the screen, increasing a pirating prevention effect.
