Display pattern preparing system |
摘要 |
A display pattern preparing system for forming picture element series data for formation and display of picture images by raster scanning. "Figure" or "Configuration" of a pattern is disassembled to be normalized. An fixed pattern memory stores, as a registered configuration data, the length of a segment by which a fixed pattern of a prescribed configuration and area crosses a scanning line in the primary direction of scanning. An analogous pattern memory stores, as parameters, a reference position data representative of a reference point for a portion of an analogous pattern through which the analogous pattern overlaps the scanning line, the analogous pattern being defined as a pattern whose configuration is analogously variable, a distance data representative of the length of the portion of the analogous pattern, and a change ratio data representative of a ratio at which the reference point changes in the auxiliary direction of scanning. The data of the fixed pattern and analogous pattern memories are read out for preparation of a position data for display of a pattern designated by the read-out data. The position data is transmitted to display units.
