Name: Mitsubishi Integrated Circuit M64282FP Image Sensor (Artificial Retina LSI) Version: ver. 1.1E Date: 5/21/98

Description

M64282FP is a 128 x 128 pixel CMOS image sensor with built-in image processing and analog image output tuning functions. This device can detect an image and process the image simultaneously as human retinas can. M64282FP can achieve smaller system size, lower power consumption, and more intelligent image processing functions.

Features

• Single 5.0V supply
• Low power dissipation ( Typ. 15 mW )
• Positive and negative image output
• Edge enhancement / extraction
• Output level & gain tuning

Application

Image input device, Gaming, Human interface for PC, etc
