DEPTH IMAGE GENERATION UTILIZING DEPTH INFORMATION RECONSTRUCTED FROM AN AMPLITUDE IMAGE

摘要

An image processing system comprises an image processor having image processing circuitry and an associated memory. The image processor is configured to identify a region of interest in an amplitude image, to detect one or more relatively low gradient regions in the region of interest, to reconstruct depth information for said one or more relatively low gradient regions, to extend the reconstructed depth information beyond said one or more relatively low gradient regions to additional pixels of the region of interest, and to generate a depth image utilizing at least portions of the reconstructed depth information and the extended reconstructed depth information. The image processor in some embodiments is adapted for coupling to an active lighting image sensor, such as an infrared sensor that does not provide depth information corresponding to the amplitude image, or an SL or ToF sensor that provides depth information corresponding to the amplitude image.
