The present invention provides an image scrolling system for scrolling an image frame contained in a window which is displayed in a monitor of the system. The image scrolling system comprises a scrolling signal generator for generating scrolling signals to perform scrolling of the image frame. Each of the scrolling signals is first converted into a corresponding two-dimensional vector which is then converted to a displacement vector. The displacement vector is added with a current coordinate of the image frame displayed within the window to obtain a next coordinate, and the image frame is scrolled to the next coordinate.
