Abstract
In an image scanner, a controller is responsive to a start command for line-scanning a document to produce a line-scan signal and providing a display of the line-scan signal on a viewing screen. While this sequence proceeds from a start position towards the end of a full scan, the user is allowed to reposition the document by viewing the screen if its orientation needs correction. The process continues until a stop command is produced or until the line-scan reaches the end of the full scan area, whichever is earlier. In response to the stop command, the controller restarts the line-scanning and display sequence from the start position to provide a full-scan of the material.
