Telecommunications
A characteristic of an image (e.g., a photograph) such that the image has all the values (0 to 100%) of gray (black and white) or color in it. Note: A continuous tone can be approximated by the use of thousands or millions of gradations of black and white or colors. The granularity of computer screens (viz., pixel size) can limit the ability to display absolute continuous tone.
