n 1: (computer science) the smallest discrete component of an
image or picture on a CRT screen (usually a colored dot);
"the greater the number of pixels per inch the greater the
resolution" [syn: pixel, pel, picture element] |

pixel
(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.

bpp
colour depth
(bpp) The number of bits of information
stored per pixel of an image or displayed by a {graphics
adapter}. The more bits there are, the more colours can be
represented, but the more memory is required to store or
display the image.
A colour can be described by the intensities of red, green and
blue (RGB) components. Allowing 8 bits (1 byte) per
component (24 bits per pixel) gives 256 levels for each
component and over 16 million different colours - more than
the human eye can distinguish. Microsoft Windows [and
others?] calls this truecolour. An image of 1024x768 with
24 bpp requires over 2 MB of memory.
"High colour" uses 16 bpp (or 15 bpp), 5 bits for blue, 5 bits
for red and 6 bits for green. This reduced colour precision
gives a slight loss of image quality at a 1/3 saving on
memory.
Standard VGA uses a palette of 16 colours (4 bpp), each
colour in the palette is 24 bit. Standard SVGA uses a
palette of 256 colours (8 bpp).
Some graphics hardware and software support 32-bit colour
depths, including an 8-bit "alpha channel" for transparency
effects.

pixel sort
(jargon) | pixel sort
n.
[Commodore users] Any compression routine which irretrievably loses
valuable data in the process of crunching it. Disparagingly used for
‘lossy’ methods such as JPEG. The theory, of course, is that these methods
are only used on photographic images in which minor loss-of-data is not
visible to the human eye. The term pixel sort implies distrust of this
theory. Compare bogo-sort.
