PURPOSE:To display a visual image only in a desired part as an optional visual image display area by setting the desired optional area where the visual image is displayed on a storage device, where a display place is set, with specific data. CONSTITUTION:The memory 13 having bits corresponding to all the dots of a display device 12 is stored with data '1' or '0' indicating whether visual image data are displayed or not in bit units. The data in the memory 13 are read out in synchronism with the display operation of the display device 12 and bit information corresponding to display positions are supplied to a selector 1 in order. The selector 11 selects the visual image data or display data of an information processing equipment according to the output bit contents of the memory 13 and outputs the data to the display device 12. Consequently, the visual image is displayed on the display screen of the display device 12 only at the part set as the visual image display area. |
