Abstract
A monolithic camera configured for a predetermined environment can be made in the following manner. The camera is formed from an integrated circuit that has a light sensitive portion that can sense light from the predetermined environment. Two or more opaque masks are disposed within the oxide layer above the light sensitive pixel array of the image sensor. These opaque masks may be formed from the 'metal' layers typically used for signal routing in image sensor integrated circuits. The opaque masks contain arrays of holes arranged so that for each pixel there is a clear path for light to reach the pixel from a corresponding part of the visual field. Each pixel is associated with a different set of holes that allows a different region of the predetermined environment to be observed.
