Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-sized video equipment adjusting apparatus used for adjusting a display device for displaying an image of a large-sized video equipment.

[0002]

2. Description of the Related Art FIG.
This will be described with reference to FIG. Here, FIG. 2 is a diagram illustrating a large-sized video device, FIG. 3 is a diagram illustrating a configuration of a display element of the large-sized video device, and FIG. 4 is a diagram illustrating adjustment of a display device of the large-sized video device.

Conventionally, as shown in FIG. 2, a large-sized video device 1 having a large video display unit 24 having a length and a width of several meters or more has been used. In particular, in recent years, theme parks and various events have become popular, and since many people can be seen at those venues at the same time, their use is becoming more and more popular.

[0006] A video signal as a video source is supplied from a VTR 22 or the like to the large-sized video device 1 via a signal processing unit 21 and displayed on a video display unit 24. The video display unit 24 is composed of a number of display elements. This display element is, for example, a fluorescent tube, and as shown in FIG.
A pixel 26 composed of green (G) and blue (B) RGB trios 25 constitutes a cell 26 by two vertical dots and four horizontal dots, and a unit 27 is constituted by three vertical cells and four horizontal cells. A predetermined number of the units 27 are grouped vertically and horizontally to form the video display unit 24.

[0005] Now, in the large-sized video equipment 1 having the above-described configuration, it is necessary to adjust each unit so that an image is displayed without unevenness. Conventionally, there is a method shown in FIG. 4 as one example of the adjustment method, and this method has been used.
That is, the worker 31 observes an image displayed from a predetermined position in front of the large-sized video device 1. Unit 27 sequentially
Observe the brightness, hue, and the like, input adjustment data to the adjustment signal transmitting device 32 so as to obtain the desired brightness and hue, and wirelessly transmit the adjustment data to the adjustment signal receiving device 33 in the large-sized video device 1. . The signal received by the adjustment signal receiving device 33 is converted into adjustment data by the control device 34, and the brightness, hue, and the like of the target unit 27 are adjusted by the data.

[0006]

However, in the method described above, since the adjustment signal is transmitted wirelessly,
Responding to these restrictions individually has been cumbersome and difficult due to restrictions by radio-related laws or differences between regions and countries. Accordingly, an object of the present invention is to provide a device capable of effectively adjusting a display image of a large-sized video device without being limited by these restrictions.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and observes an image displayed on a large-sized video device from a predetermined distance, and adjusts a display state based on the observation result. In the large-sized video equipment adjustment device, at least, an adjustment signal forming means for forming an adjustment signal based on the observation result, and transmitting the adjustment signal formed by the adjustment signal forming means, an adjustment signal transmission means using a public line, Provided on the large video equipment side, receives a signal sent by the adjustment signal transmission means, an adjustment signal receiving means using a public line, and a display state based on the adjustment signal received by the adjustment signal receiving means A large-size video equipment adjusting device is constituted by the adjusting means for automatically adjusting.

[0008] In addition, at least one of the adjustment signal transmitting means and the adjustment signal receiving means using a public line uses a portable telephone to solve the above-mentioned problem.

According to the configuration of the present invention, the transmission of adjustment data can be performed using a public line, in particular, a mobile phone. Video equipment can be adjusted.

[0010]

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 shows a system configuration of a large-sized video equipment adjusting apparatus according to the present invention.

According to the present invention, when adjusting the brightness, hue, etc. of the unit 27 of the large-sized video equipment 1, the adjustment data based on the observation result from the worker 9 located at a predetermined distance from the video display unit 24 is transmitted to a public line. In particular, it is characterized by comprising a transmitting-side system for transmitting to the large-sized video equipment 1 using a mobile phone, and a receiving-side system for receiving and adjusting the video based on the adjustment data.

The image display section 24 of the large-sized image device 1 is constituted by arranging a number of units 27 shown in FIG. On the transmitting side, the operator 9 observes the brightness, hue, etc. displayed on the unit 27, and inputs an adjustment signal input device 2 for inputting adjustment data, a modem 3 for connecting the data to a telephone line, and , On the other hand, the receiving side comprises a receiving mobile phone 6 and a modem 7 for converting the control signal into a control signal.
And a control device 8.

Next, the operation of the large-sized video equipment adjusting device having the above-described configuration will be described. Video display unit 2 of large video equipment 1
From a position at a predetermined distance from 4, the worker 9 observes the luminance, hue, and the like of the unit 27 to be adjusted. Based on the observation result, the worker 9 inputs data such as the number of the unit 27, luminance to be adjusted, and hue to the adjustment signal input device 2. The input data is transmitted from the mobile phone 4 via the modem 3 to the mobile phone 6 via the telephone station 5.

The data received by the mobile phone 6 is transmitted to a modem 7
Are converted into various control data and input to the control device 8. The unit 27 is controlled by the control device 8 based on this data, and the display state intended by the worker 9 is set.

Although the present invention has been described using a fluorescent tube as an image display section, the present invention is not limited to the above-described configuration, and is applicable to other display elements, for example, large-sized image equipment using light emitting diodes. Of course, it is good.
The transmission means is not limited to a mobile phone, but may be used via a modem in an environment where a wired telephone line is used.

[0016]

As is clear from the above description, according to the large-size video equipment adjusting apparatus of the present invention, the adjustment data is transmitted using a public line, particularly a mobile phone, so that it is limited by laws and regulations relating to radio waves, or A large-sized video device can be effectively adjusted while avoiding differences between regions and countries, and a versatile large-size video device adjustment device can be provided.
