Description
【発明の詳細な説明】 産業上の利用分野 本発明は表示装置の表示輝度制御方式に関する。[Detailed description of the invention] Industrial applications The present invention relates to a display brightness control method for a display device.
従来の技術
従来、この種の技術においては、単一の照度センサによ
り周囲の明るさ（照度）を測定し、その測定結果に基づ
き表示装置の表示輝度を調節していた。BACKGROUND OF THE INVENTION Conventionally, in this type of technology, ambient brightness (illuminance) has been measured using a single illuminance sensor, and the display brightness of a display device has been adjusted based on the measurement result.
発明が解決しようとする課題
上述した従来の技術では、単一の照度センサにより周囲
の明るさ（照度）を測定していた為に、照度センナを設
置した１箇所の明るさしか測定できず、特に、表示装置
が大型で、表示部の面積が大きい場合には、必ずしも適
切な表示輝度に出来ないという欠点がある。Problems to be Solved by the Invention In the conventional technology described above, the surrounding brightness (illuminance) was measured using a single illuminance sensor, so the brightness could only be measured at one location where the illuminance sensor was installed. In particular, when the display device is large and the area of the display section is large, there is a drawback that appropriate display brightness cannot always be achieved.

で表示するように、表示部１２を制御する。Referring to FIG. 1, the display device 11 is composed of a display section 12 that displays a light-emitting type such as a plasma display, CRT, or LED, and a brightness control section 13 that controls the intensity (brightness) of the light emission. . A plurality of illuminance sensors 14 are connected to a sensor connection section 15 , and the sensor connection section 15 is further connected to a brightness control section 13 . A plurality of illuminance sensors 14 are connected around the display device ti, and output a brightness control signal corresponding to the brightness (illuminance) of each installation location. The sensor connection unit 15 compares the input brightness control signals, selects the brightness control signal output by the illuminance sensor 1 with the brightest surroundings, and outputs it to the brightness control unit 13 of the display device 11. The brightness control unit 13 controls the display unit 12 to display at a brightness corresponding to the input brightness control signal.
前記の中で、センサ接続部１５が、各入力輝度制御信号

らない為である。これは、特に、表示部１２が大型の場
合に有効となる。Among the above, the sensor connection unit 15 selects the brightness control signal output by the illuminance sensor 14 whose surroundings are the brightest among the input brightness control signals, even when the surroundings are the brightest. This is to prevent the display from becoming difficult to see due to surrounding brightness. This is particularly effective when the display section 12 is large.

という効果が得られる。As described in detail, according to the present invention, the brightness control signal output from the brightest brightness sensor in the surrounding area is selected from among the brightness control signals from a plurality of brightness sensors, and the display is performed based on this signal. By controlling the display brightness of the device, it is possible to control the display brightness to an appropriate and easily viewable level even in a large display device.
