Abstract (en)

[origin: WO8803288A1] At least one window image (W2) in a multiwindow image displayed on the screen of a CRT (16) is displayed by being moved relative to another window image (W1). The coordinate of position on the display screen of window image (W2) being moved is renewed while the beam is flying back vertically. The moving window image (W2) is read from a memory (15) and is displayed on the display screen when the beam is present in a region designated by the coordinate of position.
