Abstract
Analog images must be sampled before being represented on the computer. In order to be visualized they must be displayed on a device that is able to reconstruct color, such as a CRT monitor. The sampling process is called rasterization; it is carried out by some sampling device, such as a scanner or TV camera, or by discretizing a continuous mathematical description of a scene, as in the case of the rendering process of image synthesis systems. The display device reconstructs the discrete image, creating an optical-electronic version that is perceived by the eye. Thus, an understanding of sampling and reconstruction is a good foundation for producing good-quality images.
