Abstract:
A 80x78 pixel general purpose vision chip for spatial focal
plane processing is presented. The size and configuration of the
processing receptive field are programmable. The chip's
architecture allows the photoreceptor cells to be small and densely
packed by performing all computation on the read-out, away from the
array. In addition to the raw intensity image, the chip outputs
four processed images in parallel. Also presented is an application
of the chip to line segment orientation detection, as found in the
retinal receptive fields of toads.
