In the present invention, an ultrasound image is displayed within the display area of a touch panel monitor. Upon receipt of a display instruction, a virtual keyboard is displayed in the display area. The virtual keyboard is displayed on a screen in front of the ultrasound image, there being partial overlap between the virtual keyboard and the ultrasound image. The touch panel monitor is provided with a touch sensor, and an operation involving touching the virtual keyboard is sensed as a keystroke on the virtual keyboard. Since the virtual keyboard is an image that can be transparently displayed, it is possible to observe the ultrasound image through the virtual keyboard as a background image. |
