Abstract
A system and method for tone mapping on a high dynamic range (HDR) image of a scene are disclosed. In one embodiment, tone mapping on the HDR image is performed using a set of bit-depths, that corresponds to a plurality of images of the scene, obtained at each unit of an irradiance range of the scene.
