picture element
<graphics> (pixel) The smallest resolvable rectangular area of an image,
either on a screen or stored in memory. Each pixel in a monochrome image has its
own brightness, from 0 for black to the maximum value (e.g. 255 for an eight-bit
pixel) for white. In a colour image, each pixel has its own brightness and
colour, usually represented as a triple of red, green and blue intensities (see
RGB).
Compare voxel.
