Abstract
Embodiments of the present invention are directed to a plurality of light sensor cells disposed in a substrate in a shared pixel arrangement. Common readout circuitry is used to simultaneously read out image information from a group of light sensor cells. The image information from the group of light sensor cells is added together simultaneously and coupled to auto-focus circuitry and/or preview circuitry to provide for better lens adjustments and preview display.
