An object of the present invention is to achieve an advanced input operation without complicating image processing. A display device of the present invention includes a display unit, an optical input unit, and an image processor. The display unit displays an image on a display screen. The optical input unit captures an image of an object approaching the display screen. The image processor detects that the object comes into contact with the display screen on the basis of a captured image captured by the optical input unit, and then performs image processing to obtain the position coordinates of the object. In the display device, the image processor divides the captured image into a plurality of regions, and performs the image processing on each of the divided regions.
