Abstract
A simple mechanical scanner has been developed, since input equipments for digital image processing are not so easilty available. Some characteristics such as resolution, signal to noise ratio and repeatability are studied. The features of this scanner, Which are S/N ratio, gradation characteristics, and frequency characteristics, are evaluated. The S/N ratio is improved by averaging the multiple scanned data, employing LOG-AMP circuit instead of the convertion table, and using LOW PASS filter.
