Abstract
A method controls a display for a copying machine including a device having two-dimensional dot displaying device in which displaying layers for at least two colors of red and green are provided and capable of displaying at least four colors red, green, white, and black by combining the displaying layers. The method is made up of the steps of providing storing device including a memory space which corresponds to a display of the dot displaying device and in which addresses are sequentially assigned. The system then calculates display information of one-dimensional absolute address position information in response to display information in which coordinate information is made into two-dimensional coordinate information. This display information is stored in the storing device, and then supplied to the displaying device so as to be displayed. The display device is primarily a dot type device.
