50 Appendix C: Glossary
Band
One of the surfaces of a buffer. A grayscale image requires
just one band. A color image requires three bands, one for
each color component.
Bandwidth
A term describing the capacity to transfer data. Greater
bandwidth is needed to sustain a higher transfer rate.
Greater bandwidth can be achieved, for example, by using a
wider bus.
Bit
A digit of a binary number. Images are described as 1-bit,
8-bit, 16-bit, etc. The numbers indicate the bits available to
store the value of each pixel in the image.
Bus
A pathway along which signals are sent, generally in two
directions, for communication of data.
Color component
One of the components that make up a color space. Typically,
each component of a color image is stored in a separate band
of a multi-band buffer.
Color space
A color space is a way of representing and describing the
complete range of perceived colors. A number of color spaces
have been developed. Common color spaces are RGB and
HSL. Both describe the same range of perceivable colors.
Composite sync
A synchronization signal made up of two components: one
horizontal and one vertical.
Contiguous memory
A block of memory occupying a single, consecutive series of
locations.
