1. A method for auto focus of a scene by an electronic device comprising a plurality of image sensors, the method comprising:
determining, by the electronic device, at least one region of interest (ROI) in the scene displayed in one of a viewfinder and a captured image frame;
determining, by the electronic device, at least one sub-ROI in the at least one ROI by performing a first level of auto focus on the at least one ROI using at least one first image sensor of the plurality of image sensors;
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 of the plurality of image sensors; 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.
