A real-time visual processing system based on a vision chip that aggregates per pixel digital processing circuitry is presented. The system supports the authors' latest vision chip and achieves high-speed, high-performance visual processing using an implementation that is small yet highly expandable and versatile. The main feature of the system is that the image capture function is programmable, with the operation of the internal pixel A-D conversion controlled from software at high time resolutions. The performance of the system is evaluated by application to basic visual processing and measurement systems, and examples of applications of the enhanced image capture function are presented.
