1 July 1990 Retinalike space variant CCD sensor

The retina is a smart sensor, but in the sense of intelligent design and not on-chip computing power. It uses a unique layout and elementary charge computing elements to implement in hardware a polar-exponential transform on visual data. The final chip includes a large section of photosites arranged in a circular pattern. Further, the pixels grow m size as radial distance increases. The retina also has a fovea (a high resolution area at the chip's center) and the computational circuitry. The sensor works and will serve as the key component of a real-time imaging system.
