Abstract
A wide dynamic range image sensor with a real-time image processing capability was implemented. The sensor comprised of FPGA circuits and a silicon retina, whose resistive networks enable instant spatial processing including smoothing and edge enhancement. In order to widen its dynamic range, the sensor exploited the technique in which the voltage signal of the photo sensor was read out several times during a single accumulation time. The multiple images with different sensitivity were integrated in the FPGA circuits. The implemented system was successful in taking edge-enhanced wide dynamic range images.
