Bit Depth
Refers to the number of data bits required to store color information about a
pixel. Larger bit depth means a greater range of color information is capable
of being encoded into each pixel. For example, 1 binary bit of memory can
only encode to either “0” or “1.” So a graphical bit depth of 1 means that the
display can only show two colors, the black and white of a monochrome
display. Four-bit color depth is capable of displaying 16 colors because there
are only 16 different combinations of 4 bits (“0000”, “0001”, “0010”... to
“1111”). Sixteen-bit color is capable of reproducing 65,536 colors, 24-bit
color can display up to 16,777,216 individual colors, and 30-bit color can
display up to one billion individual colors.
Bitmap
A bitmap is a graphic or character representation composed of individual
pixels, arranged horizontally in rows. A monochrome bitmap uses one bit per
pixel (bpp). Color bitmaps may use up to 32bpp, depending on the color depth
selected.
Brightness
The amount of white or black that is applied to all colors onscreen. By making
the screen “brighter” you are adding more white to it. This should not be
confused with luminosity, which measures the actual light level emitted from
the computer display.
Buffer
A name referring to portions of on-board video memory. One large buffer is
always used to display images to the screen; this is the “display buffer.” The
rest of offscreen memory is typically used by applications as back buffers,
z-buffers, and texture buffers.
Catalyst ® Control Center
Catalyst
®
Control Center is the successor technology to the Catalyst
®
software
formerly available only through the Windows
®
Control Panel. It has a new
user interface, providing a more interactive means of controlling such things
as 2D and 3D performance while providing immediate feedback using a more
intuitive graphical user interface.
