Stereo projection system, corrects stereo image data according to narrow passbands of interference filter units before supplying to stereo projector

摘要

The system includes a stereo projector (10) comprising a light source (11), two image forming units (12) for each half-image, two orthogonal interference filter units (13a,13b) with narrow passbands in the color ranges for red green and blue at a bandwidth of under 30 nm, for each field, and at least one projection lens (4). A correction circuit (15) receives stereo image data, and corrects the data according to the narrowband passbands of the filter units before supplying them to the stereo projector for projection.
