A New Image Sensor With Variable Sampling Control System On A Focal Plane

Abstract

In this paper, we propose a new image sensor which enables space-variant sensing. It makes use of a sampling position memory : each memory element corresponds to each pixel and it contains a binary flag data controlling pixel read out. Smart horizontal scanning utilizes the flag data and decides whether the pixel is read out. 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.
