Abstract
A method of and system for displaying high-density bit-mapped dot-matrix imaging data on a large-scale low-density dot-matrix display is disclosed. Bit-mapped image data from each of multiple and adjacently oriented dot image data groups is allocated to drive one dot of the aforesaid display. This is done through a process in which a data selection sequence standard is employed to alternately select and extract image data from each of the aforesaid dot image data groups continually and repetitively at high speed, and in which the extracted image data from each dot image group is applied to drive one dot on the display.

A method of using high-density bit-mapped image data to drive a low-density dot-matrix display device, comprising the steps of:
- allocating each of multiple dot groups oriented in mutual proximity in bit-mapped image data for one display dot on said display device;
- applying a predetermined image data selection sequence standard to alternately select one image dot of data from within each said multiple dot groups by means of a repetitive high-speed data selection operation;
- and
- supplying each dot portion of said alternately selected data to said display device as one dot of display drive data.
A method of using high-density bit-mapped image data to drive a low-density dot-matrix display device, comprising the steps of:
- allocating each of multiple dot groups oriented in mutual proximity in bit-mapped image data for one display dot on said display device;
- applying a predetermined image data selection sequence and calculation standard to alternately select specific groups of dot data within each said multiple dot groups in a repetitive high speed operation;
