Abstract:
PURPOSE:To improve the operability of a multiwindow display device by allowing an operator to execute operation only for commanding superposed display when it is necessary to simultaneously display the contents of the superposed part of the lower window on the same screen. CONSTITUTION:Dots of a certain line on a CRT 5 are continuously lighted up, the dots are observed as a thick line, and when the dots are thinned out every other dot to reduce the number of lighting dots, the dots are observed as a thin line. An ordinary multiwindow display device is provided with a thinning processing means 7 and a superposing processing part 8 by using said action so that data with low priority are tinned out by the thinning processing means 7 and OR operation between the output data of the means 7 and data with high priority is executed by the processing part 8 in a superposed area between the data with low priority and the data with high priority in an image memory to thin out the low priority information and to superposedly output the thinned data in the superposed area of both the data. Since the contents of the preceding window can be displayed simultaneously with the contents of a new window so as to be decided only by commanding superposition from an input device, the efficiency of operation can be improved.
