Abstract:
A method for displaying a projected image comprising the steps of:composing an image as a plurality of pixels, wherein a color of each of said plurality of pixels is formed as a plurality of visible light frequencies each with a selected light intensity; modulating each of said plurality of visible light frequencies to generate said selected light intensity corresponding to each of said plurality of pixels; projecting said plurality of pixels onto a projection surface of a projector screen thereby forming said projected image, wherein an area of said projection surface corresponding to a pixel of said plurality of pixels transmits to a viewer preselected bands of visible light frequencies around each of said plurality of visible light frequencies and blocks visible light frequencies outside of said preselected bands; and covering ambient light sources with an ambient light filter that absorbs said preselected bands of visible light frequencies and is substantially transparent to visible light frequencies outside of said preselected bands.
