Abstract
Briefly, in accordance with one or more embodiments, a MEMS laser beam display to implement mixed-mode depth detection comprises an imaging engine to project an image in a field of view of the MEMS laser beam display, a time of flight (TOF) depth detector to determine a distance to a target within the field of view in a first mode of depth detection, wherein the TOF depth detector determines coarse depth data of the target, and a structured light depth detector to determine a distance to the target in a second mode of depth detection, wherein the structured light depth detector determines fine depth data of the target. Depth processing circuitry may generate a composite three-dimensional (3D) image of the target, or may identify a gesture region of the target for gesture recognition.
