摘要: An adaptive image acquisition system employing a hand-held optical scanner or camera is disclosed. The system includes an adaptive camera exposure control system to adjust the camera exposure time to the media's reflectivity characteristics. The system assembles a "film-strip" of images from compressed video data, wherein redundant image data appearing in successive image frames has been removed. The system employs a correlation process between successive frames to identify the redundant frame information and determine the camera velocity. By adapting the correlation process to the velocity of the camera, the effects of variations in the velocity may be substantially eliminated.
