Abstract: An operating method of an imaging device comprising a plurality of shared pixels that share a floating diffusion node and each comprising sub-pixels covered by a micro-lens. The method involves generating a capture image from the plurality of shared pixels that receive light reflected from an object; compensating for the capture image using static phase information based on misalignment of the micro lens of each of the plurality of shared pixels; performing auto exposure control based on the compensation of the capture image; performing auto focus control based on the compensated capture image; and generating an output image by processing the compensated capture image.
