Patent attributes
An imaging method includes acquiring one or more passive light images of a scene. A region of interest in the scene is identified based on the one or more passive light images. One or more illumination zones of a plurality of illumination zones that collectively cover the region of interest is determined. Each illumination zone is sized according to active illumination emitted from a steerable illumination source. For a determined illumination zone of the one or more illumination zones, the illumination zone is individually illuminated with the active illumination from the steerable illumination source. For a pixel of a sensor array that maps to the illumination zone, a depth value of an object locus in the scene reflecting the active illumination back to the pixel is determined.
