ABSTRACT:
To effective increase the dynamic range of a pixel array, a plurality of brightness groups is set. The pixels of a pixel array are then distributed among the groups according with their likely brightness. Each image frame is scanned in the order of brightness, with the pixels in the group likely to be the brightest being scanned first and the pixels in the group likely to be the darkest being scanned last. The brightness groups are adjusted at the boundary of the frame scan.
