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.
