Abstract : Distortion occurring when tan theta mapped video is projected onto a wide angle non-tan theta display is corrected in both line direction and cross-line direction by varying the propagation time of the pixels within a line to achieve a non-distorted line and by buffering the lines of the display to allow for selective fetching of lines for display in a non-distorted manner. Both pixels and lines are delayed by variable amounts in accordance with their temporal location within a line or frame, respectively.
