Abstract

Even in the case of displaying operation display information, an image to be displayed on a display screen is prevented from being difficult to see, and an operation input by using the operation display information is always appropriately conducted. A display device receives an information signal from a base device, and displays main display information that is an image derived from a display signal of the information signal on an LCD. In the case where the display device displays a control panel for accepting an operation input from a user on the LCD, the display device controls a size change processor so that a size and a position of display of the main display information is so changed as not to overlap with display of the control panel.
