A video projector includes a reduced size spatial light modulator (400) that spatially modulates light from a light source (502) according to only a portion (e.g., ½) of a video frame at a time. A beam steerer (508, 600, 1600) steers spatially modulated light from the spatial light modulator to a correspond region (e.g., upper half, lower half) of a projection screen/surface (512) and one or more lenses (506, 510, 702, 802, 1002, 1008, 1100, 1300, 1502) insure that the spatially light modulator (400) is imaged onto the projection screen/surface (512). |
