Sensor and bandwidth constraints limit the instantaneous spatial resolution and field-of view (FOV), achievable in any visual system. In the human eye a compromise has evolved in , which resolution is high near the optical axis, but falls off with eccentricity. The effective resolution of the system is extended, by fast gaze-shifting mechanisms and a memory system that allows a form of integration over multiple, fixations. We have constructed an artificial visual system based on these concepts. The peripheral component, consists of a catadioptric video sensor that provides a panoramic FOV. The foveal component is a video, pan/tilt camera with 14 deg FOV. Calibration yields a table of …

Why it's free to use
- Filed May 14, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 14, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 14, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
