Claim 10:
11. A device comprising:
a time of flight sensor; and
a stereoscopic image acquisition device,
wherein the time of flight sensor is configured to generate a distance map of a scene and generate a corresponding distance histogram for each acquisition zone of the scene,
wherein the stereoscopic image acquisition device is configured to acquire two images of the scene at two different viewpoints, and
wherein the device comprises instructions, stored within a memory of the device, when executed causes the device to
identify regions of a depth map to be generated from the two images that corresponds to the distance map,
generate a range of values of disparities, region by region, from extreme values of the distances of the corresponding histogram, and
extrapolate distances of the scene from the disparities between the two images, wherein, for each region, the extrapolation of the distances of the scene is performed based on the range of values of the disparities for a corresponding region.
