Abstract
A photosensor assembly has multiple rows of photosensors sharing a charge transfer register. Charges from one row of photosensors are transferred through another row of photosensors to the charge transfer register, and charges from both rows of photosensors are optionally added together in the charge transfer register. The photosensors in the two rows may have different light collecting areas.
