Electronic Eyeball Uses Curved Image Sensor

Posted by timothy on from the intelligent-design dept.

AnonymousCoward writes "US researchers have made a digital imaging system designed like the human eyeball — its image sensor is on the inside of a hemisphere like your retina. Resolution is so far low, but finding a way to use silicon sensors this way offers a way around the unavoidable distortion that results from projecting a wide angle view onto a flat sensor."

    Yes. Perspective correction for flat sensors (or flat film) causes all sorts of problems, from corner softness to chromatic abeeration, and that is why camera "lenses" actually have dozens of elements (i.e., actual lenses) inside them (which in turn cause other problems, like flare). With this kind of design, you can basically get away with using a single lens (for fixed focals, anyway).
