摘要： An image projection system (10) and method is presented for optically projecting an image onto a display surface (20) with visually correct geometry and optimum image quality. The projection system (10) includes an image processing unit (12) for receiving the input image data and generating distortion-compensated image data to compensate for ensuing spatial distortions in the projection system, a projection light engine (14) for receiving the distortion-compensated image data and projecting a distortion-compensated optical image that corresponds to the distortion-compensated image data; and, an optical reflection assembly (16) comprising at least one curved mirror (39) positioned in the optical path of the distortion-compensated optical image emerging from the projection light engine for producing a displayed optical image with reduced distortion on the display surface (20).
