Abstract

PURPOSE: To enable to display figures and characters as a same video by displaying a figure video and character video on CRT alternately in every field.
CONSTITUTION: Main computer 1 outputs the information of a picture ratio, generates picture pattern 3 and character pattern 5 and stores them in figure and character information memory portions 4 and 6. Therefore, switching portion 8 switches (60 times/sce) a figure pattern and a character pattern in memory portions 4 and 6 in every field synchronously to CRT monitor portion 7, outputs them and displays 7 figures and characters repeatedly several ten times per a second. Therefore, by the residual image characteristic of CRT and human's visual sensation, figures and characters can be looked on the same picture as if they are composed in a picture.
