Abstract

PURPOSE: To make easy the recognition of a fixed region by removing temporarily the signal which displays the fixed region from the display signal for the entire figure and then, by adding a display signal which puts emphasis so that an operator can recognize the region.
CONSTITUTION: In the graphic display equipment which displays a figure on its display unit, a signal in an interval indicated by fixed-region position signal S2 is removed from display signal S1 displaying the figure by inverter 2 and AND circuit 3, and display signal S3 is outputted. Then, rise detection circuit 4 detects the rise of region position signal S2, its output and the fixed discrete value of counter 5 supplied with clocks are OR-ed by OR circuit 6, and its result is applied to FF7. Next, outputs of FF7, and outputs of change-over circuit 12 supplied with horizontal driving pulse HD and vertical driving pulse VD are, and region position signal S2 are AND-ed respectively by AND circuits 8 and 9 so as to region display signals S4 and S5, so that either display signal S6 or S7 will be outputted via OR circuits 10 and 11.
