Abstract :
A single chip CMOS video camera is presented, along with design technique and characterization results. The chip comprises a 312*287 pixel photodiode array together with all the necessary sensing, addressing and amplifying circuitry, as well as a 1000 gate logic processor, which implements synchronization timing to deliver a fully-formatted composite video signal and a further 1000 gate logic processor, which implements automatic exposure control over a wide range. There are also simple solutions for gamma correction and test.<>
