Abstract
An imaging device includes pixel circuits that include either image sensing photodiodes or phase detection autofocus (PDAF) photodiodes. The PDAF photodiodes are included in a first PDAF pixel circuit included in a first grouping of rows, and a second PDAF pixel circuit included in a second grouping of rows of a pixel array. Bitline pairs are coupled to respective columns of the pixel array. Each bitline pair includes a first bitline coupled to the first grouping of rows and a second bitline coupled to the second grouping of rows of respective columns of the pixel array. Multiplexers are configured to select one of respective first or second bitlines of each bitline pair. A PDAF multiplexer is coupled to a PDAF select signal and the second PDAF circuit through a respective bitline pair. The remaining multiplexers are coupled to a select signal and are coupled to remaining bitline pairs.
