LC82101 Image Processing

Ordering number : EN 4982A CMOS LSI LC82101 Image Processing Circuit for FAX, Copier, and OCR Products Preliminary Overview The LC82101 converts an analog image signal from a CCD or contact sensor to high-quality binary image data. The LC82101 uses an internal 8-bit A/D converter for A/D conversion, and in addition to the orthodox dithering technique, also supports an error diffusion technique that allows an even higher quality image to be acquired. These techniques apply to the whole rang.
