Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system in which an AV device for outputting video and audio is installed in a car of an elevator.

[0002]

2. Description of the Related Art Conventionally, an image display device is installed in a car of an elevator, an environmental image or the like is displayed on the screen of the image display device, and the eyes of a passenger are gathered in the image.
An elevator system has been proposed that alleviates the tension and stress caused by the approach or contact between passengers (Japanese Patent Laid-Open No. 6-211450).

For example, in the elevator system shown in FIG. 4, a video display device (19) is installed in the car (14), and the screen of the video display device (19) has a floor number relative to the environmental video Vb. The display image Vs is superimposed and displayed.

In the above elevator system, if an appropriate image capable of attracting the passenger's attention is displayed as the environmental image to be displayed on the image display device, a high effect of alleviating tension and stress can be obtained.

[0005]

By the way, the image to be displayed on the image display device is generally the copyrighted work of another person, and even if the user has the reproduction right to display the image as it is, Editing the video and modifying a part of the content to display the content is beyond the scope of the duplication right. However, in the conventional elevator system, when the car arrives at the stop floor, the number of floors is always displayed and a part of the environmental image is edited. There was a risk of infringement.

An object of the present invention is to provide an elevator system in which whether or not to edit an environmental image is automatically determined and the image display is controlled according to the result of the determination.
