2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 5-134611.
The display device described in Japanese Patent Application Laid-Open Publication No. H10-26095 is used.

In such a conventional display device, when it is desired to optimize the screen displayed on the display unit, a user or an installer sets horizontal / vertical for each display device and for each input video signal in accordance with the installation situation. It was necessary to adjust the display position, horizontal / vertical display range, luminance, contrast, and the like.

[0004] Specifically, for example, Japanese Patent Application Laid-Open No. Hei 5-13461.
In Japanese Patent Application Laid-Open Publication No. H11-107, a display device controls a screen of a display device based on setting information stored by a unit for storing setting information and a current light amount detected by a unit for detecting a light amount irradiated from the outside. In this technique, the most suitable screen for each user is displayed with only a simple operation. FIG. 5 is a block diagram showing an example of a conventional display device. Various screens are displayed on the display unit 1, and a mask member 8 capable of changing the reflectance of irradiated external light is provided on the front of the display unit 1 to make it easier to see the screen displayed on the display unit 1. Have been. The amount of external light emitted to the display unit 1 is detected by a sensor unit 7 provided near the display unit 1. A screen setting unit 2 is provided for setting the image quality of the screen displayed on the display unit 1. By operating the screen setting unit 2, the user sets the image quality so as to obtain an optimal screen for himself. be able to. The storage unit 3 that stores the reference value of the optimum screen stores the contents set by the screen setting unit 2, the level value of the external irradiation light detected by the sensor unit 7, the reflectance of the mask member 8, and the like. Information from the sensor unit 7, the screen setting unit 2, and the storage unit 3 is supplied to the display unit 1 and the mask member 8 via the control unit 6, and the image quality of the display screen and the reflectance of the mask member 8 are controlled, so that the optimal screen The following control is performed.

[0005] The operation of this conventional display device will be described. The user of the display device inputs his / her identification information from the screen setting unit 2. Next, adjustment of image quality such as hue, luminance, contrast, and the like, and adjustment of the reflectance of the mask member 8 that can change the reflectance are performed so that an optimal screen is obtained. When the setting of the optimum screen is completed, the information relating to the image quality set by the user, the external information such as the amount of irradiation near the display unit 1 detected by the sensor unit 7 and the reflectance information of the mask member 8 are classified into levels for each element. Then, the level value is stored in the storage unit 3. The image quality information adjusted by the screen setting unit 2 is sequentially displayed as a designated screen on the screen of the display unit 1 via the control unit 6 each time. Such a screen setting may be performed only when the display device is used for the first time, and when the display device is used for the second time or later, it is only necessary to input its own identification information from the screen setting unit 2.

Next, the operation in the case of using for the second time or later will be described. First, the user inputs his / her identification information from the screen setting unit 2. Next, the control unit 6 reads information stored for each screen element for each user from the storage unit 3. Further, information on the brightness of the external light currently radiated on the display unit 1 is read from the sensor unit 7. The control unit 6 generates control information by combining the difference between the level value of the external situation at the time of setting read from the storage unit 3 and the level value of the current external situation, and the level value set by the user. With the control information generated in this way, the brightness, hue,
The contrast, the reflectivity of the mask member 8, and the angle of the display unit 1 are controlled, and the screen is set to an optimum screen.
