Abstract

In this paper we present a new mixed design of the tone mapping technique used to adjust high dynamic range (HDR) image sensor luminosities. The dynamic range extension along with the tone mapping technique implementation allows covering correctly more than six orders of luminosity magnitude. The architecture is inspired from the human vision system operation. The proposed function and its architecture design as well as MATLAB emulation applied to images extracted from a linear CMOS image sensor designed in 0.35um AMS technology are illustrated along the paragraphs of the paper.
