Spatially variant flexible sampling control integrated on an image sensor
We propose a new sampling control system integrated on an image sensor. Contrary to the conventional random access pixels, the proposed sensor is able to read out spatially variant pixels at high speed, without inputting pixel address for each access. The sampling positions can be changed dynamically by rewriting the sampling position memory. Since the proposed sensor has an array memory that keeps the pixel position to be sampled. The sampling position can be dynamically changed by rewriting the memory array. It can achieve any spatially varying sampling patterns. We have made a first prototype and show results obtained by the prototype.
