Patent ID: 8506085

Claim:
A method of projecting images, comprising: providing at least first and second image projection assemblies, said first image projection assembly being positioned relative to said second projection assembly to allow said first image projection assembly to project an image beam that at least partially overlaps with an image beam projected by said second image projection assembly on a projection surface; providing an information handling system coupled to each of said first and second image projection assemblies, said information handling system comprising a common central processing unit (CPU) coupled to each of the first and second image projection assemblies and configured to process a single common image file and to selectably provide image data from said single common image file for projection by either one of said first or second image projection assemblies onto said projection surface; processing a first single common image file with said common CPU of the information handling system for projection of a first image from said image file; using said same common CPU to selectably project said first image from said first single common image file using said second image projection assembly or only using said first image projection assembly based on at least one of a file characteristic of said first image file, a user input, or a combination thereof; wherein an image projected onto said projection surface by said second image projection assembly is visible without further polarization; and wherein an image projected by said first image projection assembly onto said projection screen comprises one or more portions of light that are polarized relative to background light projected by said first image projection assembly onto said projection screen such that said image is only visible when it is cross polarized relative to the polarization of said one or more portions of light.
