Abstract: A 3D video viewing system is disclosed, wherein a special lenticular layer is attached on a video monitor which displays at least one interleaved image composed from a plurality of 2D views of a scene. A method of determining the parameters for the lenticular layer is disclosed. In particular, the width of the lenticules on the lenticular layer is determined by many factors, including the thickness, the curvature and the refractive index of the monitor; the number of 2D views to be composed into an interleaved image for display; the normal viewing distance; and the overall viewing angle of the lenticular layer itself. A number of interleaving methods for composing a plurality of 2D views into a composite view are also disclosed.
