Claim 20:
21. An imaging apparatus comprising:
a light detector array comprising a plurality of light detectors, each light detector of the plurality of light detectors operable to generate an output corresponding to an intensity of incident light, said apparatus comprising means to control the plurality of light detectors, in a first measurement mode:
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, wherein each group of proximate light detectors comprises 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, said apparatus further comprising
a light intensity measurement unit arranged to generate a light intensity measurement for each group from each received output signal of the first plurality of output signals, wherein
the means to control the plurality of light detectors is operable, in a second measurement mode:
to control the plurality of light detectors 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
the light intensity measurement unit is arranged to generate a light intensity measurement for each light detector from each received output signal of the second plurality of output signals.
