Claim Text:
1. At an image processing module of a computing device compatible with a depth camera, a method of calibrating the depth camera, the method comprising: receiving from the depth camera a native image including test light intensity information useable to derive a native depth map for a calibration scene; receiving from a high-precision test source a respective reference image taken from a same perspective as the native image and including calibration light intensity information useable to derive a reference depth map for the calibration scene independently from the native depth map; and fitting a weighting function to vary test light intensity information toward the calibration light intensity information for the calibration scene, the weighting function configured to scale light intensity information for a plurality of raw images received by the depth camera during a subsequent operation mode wherein the depth camera is operated independently from the high-precision test source.
