Abstract
A touch panel device includes a hardware key, a display unit, a detector, and a controller. The display unit displays an image on a display screen. The detector detects a position of a touch operation performed on the display screen. The controller performs setting-value change processing of changing a setting value of an object displayed at the touched position, when the hardware key is operated while the touch operation on the display screen is detected.
