摘要:
A video projector, a shutter mechanism for a video projector, and a method for reducing image blur. A shutter can include regions that are 100% transmissive to light and regions that are more than 0% transmissive (but less than 100% transmissive). The more than 0% transmissive regions raise the perceived brightness of the image relative to a shutter with 0% transmissive regions, enabling the 100% transmissive regions to be smaller. The smaller 100% transmissive regions result in reduced image blur. The more than 0% transmissive regions can include a filter that filters out certain portions of the electromagnetic spectrum of the image to provide a perceived corrected image.

This system comprises vertical platter devices (4) including a support tower (43), vertical platters (41, 42) with as many removable rings (5) for winding the film projected in the corresponding theatre, a sprocket (46) for eventual pulling of the film (3), free-turning rollers (47) for guiding the film (3), a tension roller (6) and push buttons (9) to control the operation of the vertical platters (41,42) and the sprocket (46). The system further includes auxiliary devices (7) for cutting and/or splicing the film (3).
