摘要：This application discloses an apparatus and method of processing images, hand-drawn or written on a suitable Writing Surface (21A, 21B, 21C), viewed by an Image Sensor (22A, 22B, 22C) such as a video camera, and captured by an image sensing circuit (i.e. frame grabber or similar) used for acquistion of image frames by a computer. More particularly, this invention discriminates among changes detected in these Viewed Imges in order to identify and disregard non-informational, transient and/or redundant content. Removal of such content, a writer's arm for example, from the captured image facilitates isolating meaningful changes, specifically intentional new Writing and Erasures appearing on the Writing Surface. Preserving only meaningful changes on the surface promotes optimized compressed transmission of a subset of the visual data, when used in conjunction with digital computer display systems.
