conditions in the work area and gradual shifts in color over time on monitors or
flat panel displays.
Color Curve
A color curve represents all possible intensity values (from 0 to 255) for a color
component (Red, Green, or Blue). For each color curve, the horizontal axis
represents the input value (the color value a program wants to display), while the
vertical axis represents the output value (the color value that the display driver
will write to the screen). A value of 0 (in the lower left corner) represents the
complete absence of that particular color, while a value of 255 (in the upper right
corner) represents the "full" strength for that color.
Control Point
A control point is a user-created point on the color curve. Users can change the
color of the screen by moving the control points with a mouse.
CRT
Acronym for "cathode ray tube," which is the main component of computer
monitors and TVs. Color CRTs use three separate electron beams fired through
a shadow mask and onto the back of the glass screen. The electron beams activate
separate red, green, and blue values in various strengths in order to produce a
colored image.
Direct 3D®
Part of Microsoft®'s DirectX API designed for rendering 3D graphics on Windows®
systems. It provides software developers with low-level access to functions on
graphics cards, providing the type of performance necessary for intensive 3D
applications such as games.
DisplayPort™
DisplayPort is a digital display standard that became a VESA-approved standard
in May 2006. HDMI™ is aimed primarily at the consumer electronic market, but
DisplayPort was designed with computer displays in mind. It is scalable and
extensible in terms of pixel depth and resolution, designed to work as a
comprehensive solution both for PCs and notebooks, which currently use
different signaling standards (DVI and LVDS). DisplayPort is designed as a long-
term comprehensive replacement for VGA, providing a cost-effective, scalable,
industry standard which will consolidate external (box-to-box) and internal (LCD
panel) display connections.
Dithering
A computer graphics technique that takes advantage of the human eye's
tendency to mix two colors that are adjacent to each other to produce smooth
boundary transitions. Dithering adds intermediate color values between two or
more boundaries, producing smoother, more natural look to 2D images or 3D
objects.
Dot pitch
Dot pitch specifies the sharpness of a monitor's display. It is measured in
millimeters (mm) and is the distance between the individual phosphor sub-pixels
in a CRT display or cells of the same color within an LCD display. The smaller the
number, the sharper the image. The most common dot pitches for monitors range
from .24 mm to .31 mm. Also, if a monitor with a .24 mm dot pitch is set to its highest
possible resolution, the pixel size will equal the dot pitch. If the monitor is set to
lower resolutions, the pixels will be comprised of multiple dots.
