1. Data representing a two-dimensional scene.
A digital image is composed of pixels arranged in a
rectangular array with a certain height and width. Each pixel
may consist of one or more bits of information, representing
the brightness of the image at that point and possibly
including colour information encoded as RGB triples.
Images are usually taken from the real world via a digital
camera, frame grabber, or scanner; or they may be
generated by computer, e.g. by ray tracing software.
See also image formats, image processing.

2. The image (or range) of a function is the
set of values obtained by applying the function to all
elements of its domain. So, if f : D -> C then the set f(D)
= \ f(d) | d in D \ is the image of D under f. The image is
a subset of C, the codomain.
