Abstract

When coordinate information is inputted into input device 14, display controller 13 sets input area 16 based on the input coordinate information, and instructs work station (WS) 12 to lower the contrast of the input area 16. The WS 12 then sends an image signal where the contrast of the input area 16 is lowered on the display device 11. This solves the problem that, in a case where the contrast or brightness of a display screen of an electronic board is set for viewers but not for a presenter who inputs characters and figures on the electronic board, the presenter has an uncomfortable feeling from too high contrast or brightness.
