• Composite sync

A synchronization signal made up of two components: one horizontal and one

vertical.

•DCF

Digitizer Configuration Format. A DCF defines the input data format and among

other things, how to accept or generate video timing signals such as horizontal

sync, vertical sync, and pixel clock.

• Display memory

See frame buffer.

•Exposure time

Refers to the period during which the image sensor of a camera is exposed to light.

As the length of this period increases, so does the image brightness.

•Field

One of the two halves that make up an image. One half consists of the image's

odd lines (known as the odd field); the other half consists of the image's even lines

(known as the even field).

•Frame

A single image grabbed from a video camera.

•Frame buffer

A frame buffer is a dedicated storage area often used for data transfers between

devices of differing speeds. For example, since a computer sends out data faster

than a screen can display it, the data is temporarily stored in the frame buffer. The

buffer is generally thought of as a two-dimensional surface with a certain pixel

depth.
