Abstract (en)

[origin: EP0206330A2] Screen division display wherein a screen is divided into plural portions and an independent image is displayed on each divided portion, is achieved by the provision of a plurality of image memory areas (VCB1-VCB4) each corresponding to the screen; a display management memory area (DMM) for storing the positions on the screen of the storage contents of the image memory areas; and a display controller (DCT) for displaying the storage content of the designated image memory area on a predetermined divided portion of the screen, based on the storage content of the display management memory area. Further, there are provided a designating unit (14) for designating a desired one of the plural divided portions and a display management unit (WMG) for renewing the storage content of the display management area in such a way that the position on the screen of the image memory area corresponding to the divided portion designated by the designating unit is located on the entirety of the screen.
