Method of automatically focusing on region of interest by an electronic device

Example embodiments herein provide a method of automatically focusing on a Region of Interest (ROI) by an electronic device. The method includes extracting at least one feature from at least one candidate ROI in a field of view (FOV) in the electronic device, displaying at least one indicia for the at least one candidate ROI based on the at least one feature, receiving a selection of at least oneROI from among the at least one candidate ROI for which the at least one indicia is displayed; and focusing on the at least one ROI according to the selection. 本文中示例实施例提供了种由电子设备自动聚焦于感兴趣区域(ROI)的方法。所述方法包括：在电子设备中从视场(FOV)中的至少个候选ROI提取至少个特征；基于至少个特征来显示针对至少个候选ROI的至少个标记；接收对至少个标记被显示的至少个候选ROI中的至少个ROI的选择；以及根据选择来聚焦于至少个ROI。
