Abstract

In this paper, we demonstrate analytically novel approach for Gamma Correction (GC) built at the pixel level. The analysis is based on the estimation of the dynamic range enhancement using the spatially varying time (SVE) leading its use as a Gamma-correction function. This work shows another approach of function integration where a technique (in this case SVE) used in a specific application is also used to deliver an additional functionality (in this case Gamma correction). This is what we believe is another aspect of CMOS image sensing namely intelligence in functional integration. © 2013 IEEE.
