1. A screen display control method of an electronic device, the method comprising:
- determining a resolution operation mode of a camera, the camera being configured to operate in a high resolution mode by activating all pixels of an image sensor of the camera and a low resolution mode by activating a predetermined number of pixels less than the all pixels of the image sensor of the camera;
performing a first facial recognition operation when it is determined that the camera is operating in the high resolution mode;
performing a second facial recognition operation when it is determined that the camera is operating in the low resolution mode; and
controlling a screen display of the electronic device based on the first facial recognition operation or the second facial recognition operation,wherein the first facial recognition operation includes determining a gaze position of a user,wherein the second facial recognition operation includes;
setting first configuration values of the camera,determining whether the user is present,when the user is present, changing the first configuration values of the camera to a second configuration value, anddetermining a face position of the user with respect to the electronic device while operating the camera in the low resolution mode with the second configuration value, andwherein the changing of the first configuration values of the camera to the second configuration value comprises changing at least one of frames per second, a shutter speed, or an exposure value.
