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.

Abstract: A method for automatically generating a Region Of Interest (ROI) centric image in an electronic device is provided. The method includes receiving an image frame(s), where the image frame(s) includes a plurality of objects. Further, the method includes identifying a first ROI, a second ROI, and a non-ROI in the image frame(s). Further, the method includes rescaling the second ROI in the image frame(s), summarizing the non-ROI in the image frame(s), and automatically generating the ROI centric image, where the ROI centric image includes the rescaled-first ROI, the rescaled-second ROI, the rescaled-non-ROI, and the summarized non-ROI.

Abstract: A method for optimizing a UI of an application in an electronic device is provided. The method includes detecting, by the electronic device, at least one first application installed in the electronic device, determining, by the electronic device, at least one data item associated with at least one UI of the at least one first application to be modified, modifying, by the electronic device, the at least one data item associated with the at least one UI of the at least one first application based on a level of proficiency of a user with an already used application in the electronic device, and displaying, by the electronic device, the at least one UI with the at least one modified data item of the at least one first application.

Abstract: An electronic device is provided. The electronic device includes a memory, a user interface, and at least one processor. The at least one processor is configured to determine an optimal domain from a plurality of domains based on a current context, combine the current context and a historical context of the optimal domain to determine a combined context, determine an optimal feature from a plurality of features based on the combined context and a parameter of the optimal domain, and control the user interface to output a recommendation message for the optimal feature.
