1. A semiconductor device, comprising:
a plurality of a first type of light sensing units, wherein each of the plurality of the first type of light sensing units is operable to receive a first amount of radiation; and
a plurality of a second type of light sensing units, wherein each of the plurality of the second type of light sensing units is operable to receive a second amount of radiation, and the plurality of the second type of light sensing units is arranged in an array with the plurality of the first type of light sensing units to form a pixel sensor, wherein
the first amount of radiation is smaller than the second amount of radiation, and
a first instance of the first type of light sensing unit of the plurality of the first type of light sensing units and a second instance of the first type of light sensing unit of the plurality of light sensing units are both directly between a first instance of the second type of light sensing unit of the plurality of second type of light sensing units and a second instance of the second type of light sensing unit of the plurality of second type of light sensing units, wherein the second instance of the second type of light sensing unit is a closest of the plurality of second type of light sensing units to the first instance of the second type of light sensing unit.
