Title: Digital character font enhancement device

Abstract: A device for providing various kinds of video edge information for character video is disclosed. The all-digital device employs a plurality of scan-line length shift registers which function as delay means. The shift registers are series-connected and receive the digital video information. The outputs of the shift registers and the "present" video information are supplied to short-duration delay devices, e.g. 4 bit shift registers. By appropriately combining the outputs of the short-duration delay devices, a character video and an edge signal are produced. Digital inputs and appropriate gating means can produce a variety of enhanced character fonts.
