|Additive colour mixture
||An ordinary colour mixture process in tube monitors and data/video projectors. When mixing red, green and blue light components with the same saturation, white will appear. The signal transmission usually happens splitted into an RGB signal via shielded cable.
||Selective Autofocus. Corrects blurring fast and automatically. (Disengageable in a number of devices).
||Acronym for "Accelerated Graphics Port". Along with ISA, EISA, Microchannel, LocalBus and PCI another port/Bus in the PC area. It makes graphics faster and more realistic. The AGP-bus is only suitable for Graphic cards.
||"Alternate Lighting of Surfaces". A technology for Plasma Displays to improve the image quality by doubling the lines
||Unit of measurement for the brightness of LCD projectors based on ANSI (American National Standards Institute). An area of 1 sqm on a screen is divided into 9 equally sized rectangles. The mathematical average of the light intensity in the centre of each area equals the ANSI lumens value.
|Anti Jam System
|| Prevents jamming or damaging of slides in the slide duct. To avoid any damage the slide transport is disengaged and the cooling fan contiunues to run.
|| The aperture is a measurement for the size of the opening of the lens. This size is alterable in small steps. The higher the aperture value the less light gets into the camera.
||Failure in a digital signal evolving from compression or digitalisation. Visible as image errors, aliasing, colour blocks or colour flickering, or in sound signals ambient noise such as chirping and clicking.
|| The projector recognises the input source and automatically adjusts itself.
||With this function presentations can automatically run by defining times for cross-fading, i.e., in steps of seconds from 1 - 60 seconds.
