The vision system for MAV (Micro Aerial Vehicle) must be low power consumption, light weight, and very small size. These requirements are satisfied with CMOS (Complementary Metal-Oxide-Semiconductor) image system rather than CCD (Charge Coupled Device) image system. But CMOS image sensor has obstacles to overcome that the low response and unscability of photodetector. From the viewpoint of the development of CMOS image system for MAV's vision system, the efforts were focussed on the improvement of photodetector include unit pixel detector circuit, the design of CMOS image sensor chip and camera system. Our final goal of the research is SOC (System-On-Chip) with CMOS image sensor, memory, signal processor, and embedded controller. In study on improvement of photodetector, floating gate MOSFET type photodetector was suggested. Generally, MOSFET type photodetector is compatible to standard CMOS process and operated in parasitic lateral bipolar mode. Floating gate MOSFET type photodetector was designed and fabricated by standard 1.5 n-well CMOS process. The 16 x?16 photodetector array chip with decoder and multiplexer was also designed and fabricated using the suggested photodetector in CMOS sensor chip design part. In system design part, CMOS camera system was made using commercial functional chip. Its weight and size are about 15 g and 5 cm x?4 cm x?1 cm, respectively.
