A receiver sensor captures an image of a scene onto which a code mask is projected. One or more parameters are ascertained from the captured image. Then a light source power for a projecting light source is dynamically adjusted according to the one or more parameters to improve decoding of the code mask in a subsequently captured image. Depth information for the scene may then be ascertained based on the captured image based on the code mask. In one example, the light source power is fixed at a particular illumination while an exposure time for the receiver sensor is adjusted. In another example, an exposure time for the receiver sensor is maintained/kept at a fixed value while the light source power is adjusted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic adjustment of light source power in structured light active depth sensing systems","description":"A method and device is provided that compensates for different reflectivity/absorption coefficients of objects in a scene/object when performing active depth sensing using structured light.
