LC821031 Datasheet (Sanyo Semicon Device)

LC821031, Image-Processing

Ordering number : EN 5735 CMOS LSI LC821031 Image-Processing IC for Facsimile, Copier, and OCR Products Preliminaly Overview The LC821031 converts analog video signals from CCD and contact sensors to high-quality binary image data.

It includes both an 8-bit A/D converter and a 6-bit D/A converter for setting the reference potential and creates high-quality multi-valued data using a gamma conversion technique that supports arbitrary gamma curves.

It also provides both black and white all-pi
