Common Gateway Interface, A set of rules that describe how a web server communicates with other (CGI) programs.
Common Intermediate Format, a video format used in analog video. The resolutions are 352x288 pixels for PAL and 352x240 pixels for NTSC.
A program or Internet service in which individual computers (clients) use a central computer (server) for services.
For example, a web browser is a client program that requests the service of sending a web page or files from a web server.
Complementary Metal-Oxide Semiconductor, one type of image sensor found in digital cameras.CMOS chips are easier and cheaper to make than CCDs but don't match the picture quality generally.
It is an electrical cable that consists two conductors, separated by an insulating layer. It is used to transmitting analog video in a CCTV system.
Codec stands for Coder/ Decoder, which converts analog video and audio signals into a digital format for transmission.The codec also converts received digital signals back into analog format.
Composite video is a signal that contains the luminance (brightness), chrominance (color), blanking & sync pulses and color burst information of displayed image.NTSC and PAL are examples of composite video standards.
See Image Compression.
Contrast is usually defined as a ration between the darkest and the brightest spots of an image in image processing.Images have a higher contrast level generally display a greater degree of color grayscale variation than those of lower contrast.
Central Processing Unit, the central unit in a computer containing the logic circuitry that performs the instructions of a computer's programs.The speed at which the CPU processes information internally is measured in MegaHertz (MHz) and GigaHertz (GHz).
An industry standard for mounting a lens on a camera. The distance from the flange surface to the focal points is 12.5mm.
