Abstract
A new CMOS linear autofocus sensor has been developed for 7-point wide area autofocus system of Canon's EOS Kiss III and EOS 7SLR cameras. Sensor signal of high signal-to-noise ratio, wide dynamic range and auto gain control of high precision have been realized by its pixel level unity gain amplifier and feedback-clamp noise reduction circuitry. Reductions of size and cost have also been achieved by peripheral circuits integration and COB package.
