Abstract
The graylevel image scanning system realization and design using CIS(Contact image Scanning)be amenable to recognize a papers, OMR and OCR sheet is proposed. The design technique is used CIS scanning sensor in fixing step motor and is optimized with DSP processor for inage processing, and transfer input image data par line in feeding a step unit to PC on the USB interfacer. This system is portable ad A4 size scanning. and keeps image scan processing speed 300mm/sec. The recognition percentage has 98% on the OCR and bar codes.
