1. An apparatus comprising:
a sensor comprising an array of detectors, the sensor configured to:
assign multiple detectors to a detector group corresponding to a block pixel; and
for each frame of a set of frames:
apply a specified one of a set of mask patterns in order to select outputs of the detectors in the detector group; and
aggregate the selected outputs of the detectors in the detector group to determine pixel information for the block pixel; and
at least one processor configured to:
generate the frames using the pixel information for the block pixel; and
upscale a portion of the at least one of the frames using the set of mask patterns to identify native pixels within the block pixel.
