Dynamic control method for resizing sub-windows on a screen of a display

Abstract

A dynamic control method for resizing sub-windows on a screen of a display is based on an intuitive drag-and-drop action to enlarge/shrink a sub-window and executed in a monitoring system, comprising steps as follows: pick a focal window, which presents a drag pane with at least a scale icon on its border, on a first split screen layout via a pointer tool; pick and hold one of the at least a scale icon as a drag origin with the pointer tool and activate a drag action from the drag origin to enlarge the drag pane to approximately match a corresponding first sub-window on a second split screen layout; after completing the drag action, the first sub-window is displayed on the screen and a channel image in the focal window will be transmitted to the corresponding first sub-window on the second split screen layout
