Abstract:
An electronic device includes a SPAD array and readout circuitry coupled thereto. The readout circuitry generates a depth map having a first resolution, and a signal count map having a second resolution greater than the first resolution. The depth map corresponds to distance observations to an object. The signal count map corresponds to intensity observation sets of the object, with each intensity observation set including intensity observations corresponding to a respective distance observation in the depth map. An upscaling processor is coupled to the readout circuitry to calculate upscaling factors for each intensity observation set so that each distance observation has respective upscaling factors associated therewith. The depth map is then upscaled from the first resolution to the second resolution based on the respective upscaling factors.

Claim (Index 1):
A method for operating an electronic device, the electronic device comprising an imager and an upscaling processor coupled to the imager, the method comprising:\n generating, by the imager, a first depth map and a signal count map, the first depth map having a first resolution and comprising a plurality of distance observations to an object, the signal count map having a second resolution higher than the first resolution and comprising a plurality of intensity observation sets of the object, each of the plurality of intensity observation sets comprising a plurality of intensity observations and corresponding to a respective distance observation of the plurality of distance observations in the first depth map; and upscaling, by the upscaling processor, each of the plurality of distance observations of the first depth map into a plurality of upscaled distance observations, to form a second depth map with the second resolution, wherein the upscaling comprises:\n identifying fully covered macropixels in a first intensity observation set of the plurality of intensity observation sets; \n calculating an average intensity observation using values of the fully covered macropixels in the first intensity observation set; and \n calculating a plurality of upscaling factors for the fully covered macropixels in the first intensity observation set using the average intensity observation.
