Abstract
An apparatus for generating halos about CRT display symbols, to distinguish them from background video, reads, from an image memory, video Bit signals corresponding to a CRT picture element P.sub.I,J, and the immediately surrounding CRT picture elements. A digital signal is generated therefrom representing a first Boolean Function. The intensity of the background illumination at P.sub.I,J, is unaltered, in response to a digital signal of zero, and is diminished by one-half, in response to a digital signal of one.
