ABSTRACT:
The positional resolution of a display of graphic information generated from a digital-encoded description taken from memory is improved without increasing the fine-line resolution of the display, this being done to reduce the memory required to store the digitally encoded description of the display. The departure of the pixels in the display from their normal position in a raster defined by a relatively coarse scanning line structure and limited video bandwidth is digitally encoded; and the bits of the code are stored in respective memory planes, each having an array of storage locations mapping the normal positions of pixels in the display raster.
