ABSTRACT:
A display control system has a digital interface therein. When software using a color display is executed and displayed in a monochrome monitor, this system is responsive to color code information to arbitrarily select either a hatching pattern conversion or a grey scale display according to application software or the like. The system can thus discriminate the display contents thereof.
In a color monitor that permits input of a plurality of digital signals, the display control system can convert a given piece of color code information into digital video signals according to frames and display positions in a given area of a display screen for display of natural colors. In a monochrome monitor capable of displaying video and high-intensity brightness signals, the display control system not only converts a given piece of color code information into digital video signals according to frames and display positions in a given area of a display screen, but also outputs digital video signals in a plurality of bits according to a piece of color code information, so as to display more gradations of the color code.
