Abstract

We have developed a CMOS area sensor for an auto-focus camera system, our AF SLR (Auto-Focus Single-Lens-Reflex) camera EOS-3 which achieves 45-point area auto focusing. It is fabricated using a 1.2 μm CMOS process technology. This sensor consists of new CMOS sensor cells, new CMOS memory cells, signal transfer circuits, and peak monitor circuits. This device realizes low noise characteristics by new noise cancellation technology. This sensor exhibits excellent performance, such as a high sensitivity of 26.6 V/1x·S and a wide dynamic range of 73.6 dB. It also has low power consumption, high-speed readout, and on-chip peripheral circuits.
