Abstract: A method includes using a camera to monitor a direction of focus of at least one eye of a person, wherein the person is facing the camera and a display screen, and determining an area of the display screen that is a central focus area based on the direction of focus of the at least one eye of the person. The method further includes obtaining an image to be displayed on the display screen, wherein the image has a first portion to be displayed within the central focus area and a second portion to be displayed outside the central focus area. Still further, the method includes displaying the first portion of the image using a first image resolution, and displaying the second portion of the image using a second image resolution, wherein the second image resolution is lower than the first image resolution.
