Abstract: An imaging device includes a photodiode array. The photodiodes include a first set of photodiodes configured as image sensing photodiodes and a second set of photodiodes configured as phase detection auto focus (PDAF) photodiodes. The PDAF photodiodes are arranged in at least pairs in neighboring columns and are interspersed among the image sensing photodiodes. Transfer transistors are coupled to corresponding photodiodes. The transfer transistors coupled to the image sensing photodiodes included in an active row of are controlled in response to a first transfer control signal or a second transfer control signal that control all of the image sensing photodiodes of the active row. A transfer transistor is coupled to one of a pair of the PDAF photodiodes of the active row. The first transfer transistor is controlled in response to a first PDAF control signal that is independent of the first or second transfer control signals.
