1. An information processing system comprising:
a host system that samples coordinates indicated by using an input device to acquire a background image; and
a controller that displays an output image based on the background image on a display medium,
wherein the host system notifies the controller of the coordinates; and
wherein the controller updates the background image with an update cycle longer than a sampling cycle of the coordinates, and outputs the output image with a cursor placed at the coordinates on the background image to the display medium.
