Abstract
A display device includes a display, a detector, and a controller. The display has a display surface. The display displays an image. The detector is capable of detecting at least three touch positions each on the basis of a touch on the display surface by a detection target. The controller controls the display and the detector. The controller determines whether or not a pinch operation is performed on the basis of whether or not a distance between two touch positions touched last by the detection target is changed. When determining that the pinch operation is performed, the controller performs zoom-in processing or zoom-out processing on the image using a touch position touched immediately before the last touched two touch positions as a reference point.
