Abstract
The disclosed system increases resolution of a display. The display operates at a predetermined frequency by displaying a first image at a first time and a second image at a second time. A selective screen disposed between the display and the camera includes multiple light transmitting elements. A light transmitting element A redirects a first portion of light transmitted by the display. A light transmitting element B allows a second portion of light transmitted by the display to reach the camera. The selective screen increases the resolution of the display by operating at the predetermined frequency and causing a first portion of the first image to be shown at the first time, and a second portion of the second image to be shown at the second time. The camera forms an image from the first portion of the first image, and the second portion of the second image.
