A current-mode CMOS imager using shunting inhibition-based dynamic range compression

Journal Article


Abstract


  • An ultra-wide dynamic range current-mode CMOS imager is presented. It achieves dynamic range compression by using biologically inspired shunting inhibition vision models. As a result, it features retina-like characteristics, enabling the sensor to adapt to a wide range of scene illumination conditions. Local image contrast and edge information are preserved and can be further enhanced. The properties of the shunting inhibition-based dynamic range compression can be defined by a simple set of externally-tunable parameters, making the proposed current-mode CMOS imager architecture fully programmable. The prototype was designed in full custom ALCATEL 0.5μm CMOS technology.
