摘要：An image sensor includes a plurality of photodetectors that are identically sized
and fabricated in semiconductor material with identical semiconductor processingconditions. The photodetectors are organized into virtual high-low sensitivity groupings,each including a first photodetector and a second photodetector. A plurality ofattenuators is disposed over the semiconductor material. Each one of the plurality ofattenuators is disposed along an optical path between a microlens and the firstphotodetector of each virtual high-low sensitivity grouping such that all incident lightdirected into the first photodetector is directed through a respective one of the pluralityof attenuators. There is no attenuator along a second optical path between a microlensand the second photodetector of each virtual high-low sensitivity grouping such that allthe incident light directed into the second photodetector is not directed through one ofthe plurality of attenuators.
