Abstract
PURPOSE:To easily control a presentation screen by arranging plural picture displaying terminals corresponding to respective memory planes, selecting a prescribed memory plane and controlling the screen of its corresponding picture displaying terminals. CONSTITUTION:A projector 14 for controlling a screen is selecting from a keyboard 23 and a screen control command is inputted. A program on a processor (CPU) 24 decodes data inputted from the keyboard, selects an original file A for controlling the screen and sends a prescribed graphic instruction to a graphic control circuit 1. The circuit 1 decodes the instruction outputted from the processor 24, drives an address control line 5 so as to write display data only in a memory plane 2 and writes the image of the succeeding page of the file A in the file 20 in the memory plane 2. Display data in the plane 2 are serially converted into an R signal 10b. Since the R signal 10b is inputted to a projector 14, the picture of a screen 17 is updated to the picture of the succeeding page in the file A.
