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.
