A system and method for efficiently performing a depth map recovery procedure includes an imaging device that is implemented in a single-lens stereo-shutter configuration for simultaneously capturing overlaid images corresponding to a photographic target. A depth map generator is configured to analyze the overlaid images to determine disparity values corresponding to separation distances between matching points in the overlaid images. The depth map generator then utilizes the disparity values to calculate depth values that correspond to locations in the photographic target. The depth map generator may then utilize the foregoing depth values for creating a depth map corresponding to the photographic target.
