PROJECTOR AND METHOD OF PROJECTING AN IMAGE HAVING MULTIPLE IMAGE SIZES

摘要

A front projection display system (100) selectively operates in either a "normal" television-replacement mode, which projects a smaller-sized image, or in a large-format "cinema" projection mode with a larger-sized image. A display size selection can be made automatically according to factors such as ambient light level, and/or manually under user control. In response to the display size selection, a controller (140) retrieves appropriate data from memory (145), and controls a projection lens system (130) to display an image on an image projection surface (150) in either a first, larger-sized, format or in a second, smaller-sized format.
