ABSTRACT:
An image projecting apparatus is so constructed as to generate a stereoscopic-image signal having images for right and left eyes alternatively arranged for each field, decompose an image produced by the stereoscopic-image signal into lights with predetermined components, divide the lights into first and second groups, assign the first group to a first polarized light having the directions of polarization different from each other for each period of a video field, assign the second group to a second polarized light having the directions of polarization different from each other for each period of a video field and having a direction of polarization different from that of the first polarized light, and project the first and second polarized lights, the second polarized light being delayed by one video field with respect to the first polarized light.
