<p>PURPOSE:To obtain a mobile graphic display device that can display a pattern at a desired position by inputting coordinate data on a picture plane where the display is desired for an optional mobile graphic pattern. CONSTITUTION:The serial picture signal cd4 outputted from a multiplexer 16 is supplied to a control circuit 17 together with the output signal S3 of an X window circuit 13 and the output signal S4 of a Y window circuit 14 to apply window signal processing. While the cursor picture signal cd5 applied with the window signal processing through the circuit 17 is supplied to a CRT19 via an OR gate 18 togethr with other picture signals. Thus it is possible to display a picture including a cursor on the CRT19. The signal cd4 can be delayed by an optional time td corrponding to ''0''-m dots against the output S3 of the circuit 13. In such a way, the position control of cursor pictures for each dot is executed.</p> |
