Event-based color change pixel in standard CMOS


Berner, R; Delbruck, T (2010). Event-based color change pixel in standard CMOS. In: ircuits and Systems (ISCAS), Proceedings of 2010 IEEE International Symposium, Paris, France, 30 May 2010 - 2 June 2010, 349-352.

Abstract

This paper describes a novel dichromatic spiking pixel circuit that reacts to color change but not to intensity change. It is built in standard CMOS using a buried double junction to sense wavelength information. The pixel can detect light wavelength changes of about 14nm, while not responding to intensity steps of at least a factor of three. The pixel is suitable for integration into an array and can easily be combined with a temporal log intensity contrast change pixel.
