This paper presents a Dynamic Range improvement technique which is specially well-suited to be implemented in Focal Plane Processors due to its very limited computing requirements since only local memories and a comparator are required at the pixel level. The presented algorithm employs measurements during exposure time to create a 4-bit artificial image whose histogram determines the shape of the tone-mapping curve which is applied to create the final image. Simulations results over a highiy bimodal120dB image are presented showing that both the highiy and poorly iiiuminated parts of the image keep a sufficient level of details. |
