A new image sensor with space variant sampling control on a focal plane

We propose a new sampling control system on image sensor array. Contrary to the random access pixels, the proposed sensor is able to read out spatiall y variant sampled pixels at high speed, without inputting pixel address for each access. The sampling positions can be changed dynamically by rewritin g the sampling position memory. The proposed sensor has a memory array that stores the sampling positions. It can achieve any spatially varying sampli ng patterns. A prototype of 64 x 64 pixels are fabricated under 0.7 mu m CM OS precess.
