1. A method of operating a wearable electronic device, the method comprising:
recognizing a first gesture of a hand of a user for setting a region of interest (ROI) corresponding to a view of the user in an image frame corresponding to a view of a camera;
generating a virtual display for projecting the ROI based on whether the first gesture is recognized;
determining positions of at least two hand joints of a finger of the hand in the image frame;
determining the ROI using the positions of the at least two hand joints;
extracting the ROI from the image frame;
recognizing a second gesture of the hand for adjusting a size of the ROI; and
adjusting the size of the ROI and projecting the ROI of the adjusted size onto the virtual display, based on whether the second gesture is recognized,
wherein the determining the positions of the at least two hand joints comprises:
determining a rotation angle of the hand based on the positions of the at least two hand joints; and
determining new positions of the at least two hand joints by adjusting the determined rotation angle of the hand from previous positions to the new positions, and
wherein the extracting the ROI comprises extracting the ROI based on the new positions of the at least two hand joints.
