A display system having an input device that communicates with a display device. The input device being able to: detect a track of points of contact between the input device and the display surface; write the track data to a memory; and send the track data to the display device. The display device being able to: detect positions on the display surface contacted by the input device and generate a line formed by the detected positions; toggle between a position detection mode to a position non-detection mode; instruct the input device to detect the track it is in the position non-detection mode; request the track data from the input device when it toggles to the position detection mode; synthesize the track data from the input device and the drawing data to generate image data; and display the generated image data.
