Abstract: An electronic device for auto focus is provided. The electronic device includes determining, by the electronic device, at least one region of interest (ROI) in a scene displayed in one of a viewfinder and a captured image frame and determining, by the electronic device, at least one sub ROI in the at least one ROI by performing a first level of auto focus using at least one first image sensor. Further, the method includes determining, by the electronic device, at least one focused sub ROI by performing a second level of auto focus on the at least one sub ROI using at least one second image sensor and rendering, by the electronic device, a focus transition for the at least one focused sub ROI to one of the viewfinder and the captured image frame.
