Abstract :
This paper describes a real-time vision system of which the pixel contains a photo detector, an analog-to-digital converter (ADC), and a digital processing element. The pixel-parallel processing array combined with a dedicated real-time control structure enables real-time visual processing at a high frame rate. The in-pixel programmable ADC offers flexible imaging capability with enhanced dynamic range. The system implementation issues are also described.
