Image Sensor Architecture for Arbitrarily Directional Motion Detection Using Spacial Propagation Delay of Excitement Signal

Abstract

The integration of signal processing circuit in imase sensor, so called 'Vision Chip' is widely studied, but most of them don't aim at extracting image's meaning, which is often useful for the application of robot vision. In this paper, we propose a novel architecture for image sensor detecting the speed and the direction of moving point on focal plain. This architecture has an possibility to solve the direction dependency problem derived from matrix placement of pixels, and we consider a basic architecture for arbitrarily directional motion detection.
