Abstract
A problem is to provide a cursor movement control method by which labor necessary for a movement of a cursor can be reduced and convenience of a user can be improved even when a plurality of screens is displayed on one display device, a computer program, a cursor movement control device, and an image display system. A technical solution is such that a display image creation unit (13) sets a region in a display image corresponding to a display region A to a region a and a region in the display image corresponding to a display region B to a region b, and allocates the regions a and b into the display image. An input unit (12) receives an instruction for whether or not to superposedly display the display region B on the display region A on the display screen (54). A cursor movement control unit (15) controls the movement of the cursor between the region a and the region b according to the received instruction for a superposed display.
