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.

LC821031 Features

* Number of pixels processed: 3072 pixels/line

* Processing speed: 250 ns/pixel, maximum (When CLKIN = 32 MHz)

* 8-bit A/D converter (Includes a sensor signal timing adjustment function.)

* 6-bit D/A converter for setting the A/D converter reference potential
