[Table 1]

[0032]

[Table 2]

By inputting a luminance mode from the operation panel 2a, a luminance setting command is output to each large-sized video display device 1. CPU that has received the brightness setting command
Reference numeral 8 refers to a luminance table stored in the ROM 7 to obtain a luminance value corresponding to the luminance mode set and instructed.
A luminance value is set in the display panel control memory 9 as control data. The control device 6 displays the control data and the video data (RGB data) with the luminance value stored in the display panel control memory 9 by changing the value of the video data by the arithmetic means provided on the display panel 3 side. An image is displayed on the board 3. According to the tables shown in (Table 1) and (Table 2), if the operator (operator) sets the luminance mode '5', the display panel A sets the luminance to 160 and the display panel B sets the luminance to 80. Is done.

When each control device 6 receives a luminance setting instruction from the operation panel 2a or the control operation unit by an operator's operation, it can display an image at a luminance corresponding to each condition (for example, an installation location). For example, it is assumed that the display panel A is installed outdoors and the display panel B is installed indoors. Since the display panel B is indoors, it may not be necessary to operate at such a high luminance. In this case, when it is desired to operate both display panels at the highest luminance, a command to set the luminance mode '8' to both control devices 6 by one operation from the operation panel 2a is transmitted, thereby displaying the display panels A and B. The brightness is set.

Register the coefficient to be changed. As a result, when operation in an environment in which the illumination around the display panel A is red and the illumination around the display panel B is blue, the table number '3' is selected by operating the operation panel 2a. The color temperature of A and the display panel B can be adjusted at the same time, and an image can be displayed so as to be familiar with the surrounding atmosphere.

By owning a conversion table for each display panel, color temperature conversion corresponding to each condition (installation location, element characteristics, etc.) can be performed, and a plurality of operations can be performed by one operation on the operation panel 2a. The color temperature of the display panel can be set.

In the above-described color temperature control, video data converted based on the color temperature data is stored in the display panel control memory 9, and an image is displayed based on the control data. Like the brightness control

If the number of vertical dots on the upper side is determined, the number of horizontal dots on the display panel for displaying the number of horizontal dots on the image is determined by the aspect ratio. For example, if the scaling ratio is 50
%, And the image length is 480 dots, the image length is displayed at 240 dots vertically on the display panel. Here, when the aspect ratio is 3: 4, 240 dots vertically and 3 dots on the display panel are displayed. : The number of horizontal dots of the video is displayed on 320 dots having a ratio of 4: 4. Also, even if the number of vertical dots on the display panel for displaying the number of vertical dots of the video according to the enlargement / reduction ratio exceeds the number of dots constituting the display panel, it is assumed that there are virtual dots, and Is obtained, and the number of dots is made to correspond to the number of horizontal dots of the image.
