• abstract: The author explains how a device small enough to fit inside a car's rear-view mirror can be programmed to see. The device is a CMOS based image sensor developed by VLSI Vision Ltd., Edinburgh. The sensor overcomes the previous problem of placing all pixel outputs through a single charge amplifier by using a separate charge-sense amplifier at the head of each column of pixels. The author describes how the sensor operates. The incorporation of this sensor into a programmable machine-vision system called the imputer is discussed.<>
