Displaying an Image

Abstract

An additive display device is the primary user interface at all stages of digital imaging, converting an image from numerical representation to visual form. It has a screen with a fixed array of pixels of fixed pitch, which determines the displayed size of an image, and the resolving power of the display. An sRGB screen has three independent light sources per pixel, which combine additively to show any sRGB colour. An sRGB image is encoded with gamma 0.4545 and displayed with gamma 2.2. A different display gamma can be imposed on a stored file by program.
