Anti-Flicker reduces the amount of display flicker. Display
flicker is both a distraction and tiring to your eyes, and is most
pronounced when text is being displayed.
Brightness is related to the amount of light emitted by your
display or reflected from an object.
Contrast is a ratio of how far the whitest whites are from the
blackest blacks. If the contrast is too high, the image may look
stark, like pure white squares on a jet-black background. If the
contrast is too low, the image may look gray or washed out.
Hue is generally not adjusted. Depending on the TV, however,
it may be necessary or desirable to adjust the hue to
approximate the monitor’s display.
Hue, saturation, and brightness are the three qualities which
constitute what we normally refer to as “color”.
• Hue, often used as a synonym for “color”, is the quality
that distinguishes among red, green, yellow, and so on.
• Saturation is the amount of color present that distinguishes
pale or washed-out colors from vivid ones. Extreme
settings, will produce black & white (greyscale) output.

Glossary
Alpha blending When an image has an alpha value for each pixel, this
tells how much to blend the colors from the image with
the background colors. The lower the alpha values the
more transparent the image looks.
Anti-aliasing Method used to remove the jagginess of an image.
When anti-aliasing is used, the edges of an image appear
smooth and usually somewhat blurry.
Anisotropic Filtering This filtering technique uses a rectangular filtering
pattern to render smoother, crisper images.
Aspect Ratio The proportions of a display expressed as a ratio of
width and height. Common ratios include 4:3 for TV
and CRTs, 5:4 for LCDs and 16:9 for widescreen
displays.
Back buffer A type of offscreen memory used to provide smooth
video and 2D graphics acceleration. This technique uses
two frame buffers, often referred to as “doublebuffering”. While one buffer is being displayed, a
second buffer of the same size, the “back” buffer, holds
the frame being worked on.
Once a new frame is ready in the back buffer it is copied
to the front buffer - the display screen. In this way, you
will only see complete, smooth frames, and not the
operations performed on them.
In order to increase performance, all memory used for
back buffers are on your ATI graphics accelerator card.
Bilinear Filtering When texture mapping is performed an image can
become very “blocky” or “pixelated” when the texture is
viewed close up. Bilinear filtering samples four texture
pixels, takes the weighted average of these pixels and
applies the average of these “texels”. This blended color
is used to provide a smoother looking texture.
25
Page 29
Bitmap A bitmap is a graphics 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 32-bpp, depending
on the number of colors desired.
Buffers Your ATI accelerator card includes on-board memory
which is used in a number of ways. Buffers are portions
of this memory used as temporary storage on your card.
One large buffer is always used to display the screen you
see; this is the “display buffer”. The rest of offscreen
memory is used by applications as back buffers,
z-buffers, and texture buffers.
Color Depth Color depth is the number of color shades available on
your display. The color depth of your monitor usually
includes; 256 colors (8-bpp), Thousands of colors
(16-bpp), and Millions of colors (32-bpp), and is also
measured in bits per pixel (bpp).
Note: The ATI 3D Accelerator only functions in
Thousands and Millions of colors modes.
Fog The blending of an object with a fixed color as objects
or pixels increase distance away from the viewer.
Frame Buffer Memory buffer used to store the image being displayed.
Gouraud Shading One of the more sophisticated shading methods used to
produce a smooth lighting effect across a 3D object. A
specific color is used at each vertice of a triangle or
polygon, and interpolated across the entire face.
HYPER Z
™
III A memory bandwidth saving technology that boosts
rendering performance.
MIP Map Multum In Parvum (Latin) means “many in one.” It is a
method of increasing quality of a texture map by storing
multiple resolutions of the same image and dynamically
switching between them depending on the size and
depth of the object being textured.
Offscreen Memory An area of memory used to preload and place images so
that they can be quickly drawn on the screen. Offscreen
memory refers to all the memory on your ATI
accelerator card that is not taken up by the front buffer,
which holds the display screen that you see.
26
Page 30
Pixel, Pel Picture element. Smallest addressable area of the
computer screen. Pixels on computer displays are
square; pixels on NTSC televisions have a 4:3 aspect
ratio.
Refresh Rate Also referred to as “vertical refresh rate”. The rate at
which a monitor or television can redraw the screen
from top to bottom. NTSC television systems have a
refresh rate of approximately 60 Hz (but only draw onehalf of the video frame in one pass); computer displays
typically have refresh rates of 75 Hz or more. At a
refresh rate of 70 Hz and lower, screen flicker is often
noticeable.
SMARTSHADER
2.1
™
An advanced programmable pixel and vertex shader
technology which delivers complex and realistic
textures and lighting without slowing performance.
SMOOTHVISION
2.1
™
Full Screen Anti-Aliasing technology designed to
minimize jagged edges resulting in smooth images.
Specular Highlight The bright, usually small, intense light reflected from a
3-D surface with a high refraction value.
Texture Mapping Mapping, or placing, an image onto an object. Images of
realistic surfaces are placed on 3D models to create a
richer and more complex visual effect.
Trilinear Filtering Sampling method used to produce the most realistic
looking 3D objects. Trilinear filtering averages one of
the bilinear filter MIP Map levels along with the
standard MIP Map samples.
VERSAVISION
™
ATI’s hardware accelerated display rotation and scaling
technology. Any desktop can now be rotated 90 degrees
left or right, or even 180 degrees, while maintaining the
full feature set of other ATI 2D and 3D technologies,
such as SMOOTHVISION. VERSAVISION works
with single or multiple displays.
Z-buffer A z-buffer is an area of off-screen memory used to hold
“depth” information. For each dot, or pixel, in the
display buffer, there is a corresponding dot in the
z-buffer which holds the depth (z) value for the display
pixel. The depth data helps the ATI accelerator card
decide what 3D objects are in front of other 3D objects.
The larger the 3D window, the larger the z-buffer is in
memory.
