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 14):
A method of upscaling depth maps produced by a single-photon avalanche diode (SPAD) array using an upscaling processor, the method comprising:\n receiving, by the upscaling processor, a first depth map having a first resolution and a signal count map having a second resolution higher than the first resolution, the first depth map comprising a plurality of distance observations to an object, the signal count map comprising a plurality of intensity observation sets of the object, each of the plurality of intensity observation sets comprising a plurality of intensity observations corresponding to a respective distance observation of the plurality of distance observations; identifying, by the upscaling processor, background macropixels in each of the plurality of intensity observation sets; identifying, by the upscaling processor, partially covered macropixels in each of the plurality of intensity observation sets; calculating, by the upscaling processor, an average intensity observation for each of the plurality of intensity observation sets using values of fully covered macropixels in the each of the plurality of intensity observation sets, wherein the fully covered macropixels are macropixels in each of the plurality of intensity observation sets other than the partially covered macropixels and other than the background macropixels; and calculating, by the upscaling processor, a second depth map having the second resolution using the first depth map, the signal count map, and the average intensity observation of each of the plurality of intensity observation sets.
