Abstract
A method for displaying an image on a display surface which preserves context and detail information when the image is compressed to fit onto a display surface. The image is transformed from a plane onto a truncated pyramid, and then a three-dimensional perspective projection of the pyramid is taken. This perspective provides a detailed view of portions of the image underlying an image lens panel, and context view of remaining portions of the image, which underlie side panels. The side panels are rotated and expanded to fill the remainder of the view after the detailed image under the image lens is expanded.
