1. A stereoscopic imaging device that captures stereoscopic images of a scene, comprising: a left array of image sensing pixels; a right array of image sensing pixels that is separated from the left array by a stereo baseline, wherein the left and right arrays capture one or more stereoscopic images with an adjustable point of convergence and wherein any elements in the scene that are at the adjustable point of convergence have zero horizontal disparity between images captured by the left array and images captured by the right array; circuitry that identifies a region of interest in the scene, wherein there is a given distance between the region of interest and the stereoscopic imaging device; and convergence control circuitry that adjusts the adjustable point of convergence of the left and right arrays using information on the given distance between the region of interest and the stereoscopic imaging device.
