Abstract
A method for reading out an image signal includes providing at least two photosensitive regions and providing at least two transfer gates respectively associated with each photosensitive region. The method also includes providing a common charge-to-voltage conversion region electrically connected to the transfer gates and providing a reset mechanism that resets the common charge-to-voltage conversion region. After transferring charge from at least one of the photo-sensitive regions, all the transfer gates are disabled at a first time. The method further includes enabling at least one transfer gate at a subsequent second time and transferring charge from at least one of the photosensitive regions at a subsequent third time while the at least one transfer gate from the second time remains enabled.
