Abstract:
1. An off-axis projection system for displaying an image on a display surface based on input image data, comprising: an image processing unit for receiving the input image data representing a two-dimensional array of pixels, and electronically warping the input image data, prior to projection, to generate two-dimensional electronically warped image data; a projection light engine having a display device with means to modulate a two-dimensional array of pixels, said light engine being coupled to the image processing unit and adapted for receiving the electronically warped image data, modulating a two-dimensional warped image corresponding to the electronically warped image data on the display device, and projecting the two-dimensional warped image to create a projected image; and, an optical reflection assembly coupled to the projection light engine adapted to direct the projected image onto the display surface, said optical reflection assembly comprising at least one curved mirror,
