摘要
In a figure displaying device which generates edge data corresponding to the individual horizontal scanning lines, to display figures on the raster scanning type Braun tube relying upon the edge data, the improvement comprising at least two sets of memory groups which have a capacity corresponding to the number of picture elements at positions of even numbers and odd numbers on the horizontal scanning lines, and which store predetermined data in the addresses corresponding to the picture elements at which edges are present, at least two converter means for converting the data read in parallel from the memory groups into series data, selection means for selecting the outputs of said converter means, and control means for displaying figures on the monitor responsive to the output of said selection means.
