Abstract: A technique is described herein for reducing blur caused by an imaging assembly of a depth camera system. In a runtime phase, the technique involves receiving a sensor image that is generated in response to return radiation reflected from a scene. The return radiation passes through an optical element (such as a visor element) of the imaging assembly, which produces blur due to the scattering of radiation. The technique then deconvolves the sensor image with a kernel, to provide a blur-reduced image. The kernel represents a point spread function that describes the distortion-related characteristics of at least the optical element. The technique then uses the blur-reduced image to calculate a depth image. The technique also encompasses a calibration-phase process for generating the kernel by modeling blur that occurs near an edge of a test object within a test image.
