Paper Abstract

An image scanner/digitizer has been developed which utilizes solid state array sensors to achieve high-speed, high-resolution scanning of black and white images. The internal 68000 microprocessor-controlled unit is desk-top sized, easy to interface, and simple to operate. It incorporates the following features: o Flat bed input platen o Two selectable input scan widths o Cursor cropping of scanned area to minimize digital data storage requirements o Eight bit per pixel digitization of imagery o One bit per pixel digitization of line art o Reflected or transmitted white light scanning o Automatic pre-scan sensor calibration The scanner provides high fidelity digitization of imagery for a variety of applications, including CAD/CAM and medical image enhancement. It is currently being used to input line graphics and photographs to an all-electronic image assembly subsystem. Proprietary software provides a powerful, user-friendly menu of the image processing and page layout functions required for electronic page composition. Simple operator interactions with a data tablet invoke and control the operations of: o Contrast/brightness enhancements o Image placement and rotation o Software-interpolated image sizing o Outlining o Cropping and stripping o Edge enhancement o Small area modifications o Graphic creation and modification o Application of spot colors from a user-defined color palette
