Display apparatus, display system, and display control method for display system

A display control method for a display system comprised of a display control apparatus which is connected to a display information supply apparatus for supplying display information, receives the display information from the display information supply apparatus, performs predetermined image processing of the display information, and outputs display image information, and a display apparatus for displaying the display image information supplied from the display control apparatus on a display, said method comprising the steps of:

• setting, by a setting switch in the display apparatus, a display condition of the display;
• determining whether the display condition set in said setting step is changed at every first time interval;
• detecting a temperature of the display apparatus at every second time interval longer than said first time interval and at the time when said determination step determines that the display condition is changed;
• transmitting the setting state and the detected temperature data to the display control apparatus;
• and
• generating the display image information by performing image processing of the display information supplied from the display information supply apparatus in accordance with both the received setting state and the temperature data of the display apparatus, so that the image processing of the display control apparatus can be controlled by the setting switch and the temperature data of the display apparatus.

A display apparatus for displaying display image information supplied from a display control apparatus for outputting the display image information, comprising:

• first communication means for performing a communication with said display control apparatus;
• display means for displaying the display image information received from said display control apparatus via said first communication means on a screen;
• a setting switch for setting a display condition of said display means;
• determination means for determining whether or not the display condition set by said setting switch is changed at every first time interval;
• temperature detection means for detecting temperature data of said display apparatus at every second time interval longer than said first time interval, and at the time when said determination means determines that the display condition is changed;
• and
• transmission means for transmitting a setting state of said setting switch and the temperature data of said display apparatus to said display control apparatus via said first communication means,
• wherein the image processing of said display control apparatus can be controlled by both of said setting switch and the temperature data of said display apparatus.
