Beschreibung
Zusammenfassung:	A photosensor has a masking layer having an opening over a central photodiode and a first adjacent photodiode, the first adjacent photodiode covered by the masking layer and located sufficiently near the central photodiode that at least some light admitted through the opening over the central photodiode reaches the first adjacent photodiode through the central photodiode. The photosensor also has a second adjacent photodiode; the second adjacent photodiode covered by the masking layer and located sufficiently near the first adjacent photodiode that at least some light admitted through the opening over the central photodiode is capable of reaching the second adjacent photodiode through the first adjacent photodiode. Circuitry is provided for reading the photodiodes and generating a blue, a green, and a red channel signal by processing signals read from the photodiodes.
