1 color separation
"A decomposed layer of a full-color image used in printing. Typical printing processes use four color separations (cyan, magenta, yellow, and black) which combine together to produce the final image." -
2 image color matching
The process of image output correction to match the same colors that were scanned or input. -
3 color keying
The process of specifying colors of an image that are not transferred in a transparent bit-block transfer operation. -
4 threshold filtering
"The process of reducing a full-color image to an eight-color image. This is done by setting a value for a threshold, which is the cutoff value for each color component of a sample." -
5 grayscale
"A sequence of shades ranging from black through white, used in computer graphics to add detail to images or to represent a color image on a monochrome output device." -
6 scene
"An image and color combination designed to personalize a display window that is viewable to other people. For example, in Windows Live Messenger, someone can choose from a set of available scenes, or upload their own background image. They can also use a default color suggestion, or specify their own color. Someone's personalization is displayed in the main Messenger window (visible to themselves) and also in the main conversation window (visible to others)." -
7 rendering
"The creation of an image containing geometric models, using color and shading to give the image a realistic look. Usually part of a geometric modeling package such as a CAD program, rendering uses mathematics to describe the location of a light source in relation to the object and to calculate the way in which the light would create highlights, shading, and variations in color. The degree of realism can range from opaque, shaded polygons to images approximating photographs in their complexity." -
8 rendering intent
"In color management, the approach used to map the colors specified in an image file to the color gamut of your monitor or printer. The color gamut is the range of color that a device can produce." -
9 dithering
"A method to display a range of colors with a limited palette. Each pixel on the source image is represented by multiple pixels (usually a 2x2 square) on the destination image. From a distance, the eye blends the multiple pixels into one color that has more shades than the original palette. The techniques results in a better visual appearance than the removal of low precision bits." -
10 pixel shader
"A graphics function which calculates computer image effects pixel by pixel allowing control of the lighting, shading and color of each individual pixel." -
11 background
"The color or image that appears behind the content of a visual element, for example, behind the text that is displayed in a TextBox control or on your graphical user interface." -
12 white point
The lightest color that can be reproduced by a display device. Black point and white point are set to achieve optimal highlights and shadows in an image. -
13 shader
"A graphics function which calculates computer image effects pixel by pixel allowing control of the lighting, shading and color of each individual pixel." -
14 personalization
A feature that enables the user to change a site's color scheme and background image.
