  • gamma correction — (hardware)   Adjustments applied during the display of a digital representation of colour on a screen in order to compensate for the fact that the Cathode Ray Tubes used in computer monitors (and televisions) produce a light intensity which is not proportional to the input voltage. The light intensity is actually proportional to the input voltage raised to the inverse power of some constant, called gamma. Its value varies from one display to another, but is usually around 2.5. Because it is more intuitive for the colour components (red, green and blue) to be varied linearly in the computer, the actual voltages sent to the monitor by the display hardware must be adjusted in order to make the colour component intensity on the screen proportional to the value stored in the computer's display memory. This process is most easily achieved by a dedicated module in the display hardware which simply scales the outputs of the display memory before sending them to the digital-to-analogue converters. More expensive graphics cards and workstations (particularly those used for CAD applications) will have a gamma correction facility. In combination with the "white-point" gamma correction is used to achieve precise colour matching.

  • graphics adaptor — (hardware, graphics)   (Or "graphics adapter", "graphics card", "video adaptor", etc.) A circuit board fitted to a computer, especially an IBM PC, containing the necessary video memory and other electronics to provide a bitmap display.

These parameters are also limited by the monitor to which the adaptor is connected. A number of such display standards, e.g. SVGA, have become common and different software requires or supports different sets.

  • image processing — (graphics)   Computer manipulation of images. Some of the many algorithms used in image processing include convolution (on which many others are based), FFT, DCT, thinning (or skeletonisation), edge detection and contrast enhancement. These are usually implemented in software but may also use special purpose hardware for speed. Image processing contrasts with computer graphics, which is usually more concerned with the generation of artificial images, and visualisation, which attempts to understand (real-world) data by displaying it as an artificial image (e.g. a graph). Image processing is used in image recognition and computer vision. See also Pilot European Image Processing Archive.
