Abstract
A method and an apparatus for enhancing edges in computer-generated images. Each image frame is divided into non-overlapping blocks of pixels. Each block is characterized by a value proportional to the contrast of the block. Each block is checked to see if its contrast is greater than a user-selectable contrast threshold. If the block contrast is greater than the threshold, a window level operation is performed upon that pixel block. This method restricts the window level edge enhancement function to just the set of pixel blocks that have a high contrast value and may contain an edge.
