Abstract :
We propose a new sampling control system for an image sensor. Contrary to the 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 sampling position memory that stores the sampling control order, it is able to easily control sampling position. We can achieve any spatially varying sampling patterns
