frame buffer

(hardware)
Part of a video system in which an image is stored, pixel by pixel and which is used to refresh a raster image. The term "video memory" suggests a fairly static display whereas a frame buffer holds one frame from a sequence of frames forming a moving image.

Frame buffers are found in frame grabbers and time base correction systems, for example.

frame buffer

An area of memory used to hold the frame of data that is continuously being sent to the screen. The buffer is the size of the maximum image that can be displayed and may be a separate memory bank on the graphics card (display adapter) or a reserved part of regular memory. Sophisticated graphics systems are built with several memory planes, each holding one or more bits of the pixel. See video RAM. See also frame grabber.
