1. A method of measuring light intensity for imaging using a light detector array comprising a plurality of light detectors, each light detector of the plurality of light detectors arranged to generate an output corresponding to an intensity of incident light, said method comprising, in a first measurement mode:
controlling the light detector array to generate a first plurality of output signals, each output signal of the first plurality of output signals generated by one of a plurality of groups of proximate light detectors of the light detector array, each group of proximate light detectors comprising a first light detector and second light detector forming a light detector pair, each output signal of the first plurality of output signals corresponding to a difference between the light intensity detected by the light detectors of the group of proximate light detectors, and
generating a light intensity measurement for each group from each received output signal of the first plurality of output signals,
the method further comprising, in a second measurement mode:
controlling the light detector array to generate a second plurality of output signals, each output signal of the second plurality of output signals generated by one of the light detectors, and
generating a light intensity measurement for each light detector from each received output signal of the second plurality of output signals.
