First Claim
1. A display device, comprising:
- receiving means for receiving an information signal;
a display element for displaying an image corresponding to a display signal of the information signal that is received from the receiving means;
operation display processing means for displaying operation display information for receiving an operation input from a user on the display element;
adjusting means for adjusting at least a size of the image corresponding to the display signal of the information signal from the receiving means according to the operation display information so that the image is displayed on the display element;
touch position detecting means disposed on a display screen of the display element for detecting a touch position on the display screen which is touched by the user; and

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.

5. A display information using method in a two-way communication system in which a display device receives an information signal from a base device and displays an image corresponding to a display signal of the information signal on a display element of the display device, and the base device receives an operation signal corresponding to an operation input of a user from the display device and conducts processing corresponding to the operation signal, the method comprising the steps of:
-
in the display device, receiving a display instruction input of operation display information;
adjusting at least a size of the image corresponding to the display signal according to the operation display information when receiving the display instruction input in the receiving step;
combining the display signal for displaying the image at least the size of which is adjusted in the adjusting step and the display signal of the operation display information;
displaying the image corresponding to the display signal combined in the combining step;
detecting a touch position on a display screen which is touched by a user through touch position detecting means disposed on the display screen of the display element;
forming a remote control signal corresponding to a display item of the operation display information displayed at the touch position on the display screen which is detected in the touch position detecting step; and
transmitting the remote control signal formed in the forming step;
in the base device, receiving the remote control signal from the display device; and
forming an operation signal to an external input device and transmitting the operation signal to the external input device when the remote control signal received in the operation signal receiving step is a control signal to the external input device which is a supplier of the information signal. - View Dependent Claims (6)
