Abstract
Content

The figure shows a complementary metal oxide/semiconductor (CMOS) integrated circuit that contains all of the electronic circuitry of a programmable active-pixel-sensor digital camera. Heretofore, digital cameras have been assembled from charge-coupled-device (CCD) chips, separate analog-to-digital converters, and separate units that perform timing, control, and interface functions; each unit adds to the size, cost, and power consumption of a camera. The present single-chip camera is a prototype developed for many applications within the space program. It also meets the demands of a large potential market for compact, low-power-consumption, and (eventually) inexpensive portable digital cameras. The chip has been packaged as a low-power camera occupying only 1 cm3 (0.06 in.3), exclusive of optics, with an all-digital 5-wire serial interface. The chip is also being incorporated, along with a wireless interface unit, into a battery-operated camera with a volume of less than 32 cm3 (2 in.3).
