Graphics video resolution improvement apparatus










Image Number 6 for United States Patent #4484188.

A video signal generation apparatus improves the resolution of the video signal by forming additional video scan lines between the successive scan lines by combining the video attributes of adjacent scan lines. This invention is particularly applicable to video display terminals and small computing systems which employ digital memories for storing graphic characters for display via a raster scan video display device. The graphics resolution may be improved in two dimensions by combining the techniques of averaging or smoothing a graphic character generated scan line by averaging or integrating a video attribute of the scan line over a period approximating the period of a individual picture element, together with forming new scan lines by combining the video attributes of adjacent graphic character generated scan lines. In a preferred embodiment of this invention an interlace scan system is formed using graphic character generated scan lines for the first half frame and the interpolated scan lines for the second half frame.
