Abstract
A pixel cell for differential light sensing includes a plurality of photodiodes and a corresponding plurality of storage diodes. Each storage diode is disposed between a first adjacent photodiode and a second adjacent photodiode, and each storage diode is configured to receive photo charges from either or both of the first adjacent photodiode and the second adjacent photodiode. Each photodiode is disposed between a first adjacent storage diode and a second adjacent storage diode, and each photodiode is configured to transfer photo charges to either or both of the first adjacent storage diode and the second adjacent storage diode.
