Abstract
An image-projection display (10) includes a combiner (12) which is transparent to allow a view therethrough, and which is also at least partially reflective so that an image projected onto a surface of the combiner is reflected to a viewer. The display apparatus includes off-axis projection factors so that a rectilinear projected image would be perceived by the viewer as being distorted. A projector portion (20) of the display (10) includes an image source (36, 38) and a corrector element (46), as well as means (38, 46) for physically dislocating pixel elements of a rectilinear image so that the image as projected is de-linearized with compensatory distortion causing the image viewed by the viewer to be perceived with restored rectilinearity.
