[0033]

[0034] figure 1 It is a block diagram showing the configuration of the multi-display system of the first embodiment. like figure 1 As shown, the multi-display system has a multi-display 5 , a video signal processing device 6 and a control device 7 .

[0035] The multi-monitor 5 is a monitor group in which a plurality of monitors 1 to 4 are arranged in a grid, for example, and receives and displays video generated by the video signal processing device 6 based on a video signal via a DVI cable, for example.

[0036] Displays 1 to 4 are DLP (Digital Light Processing: Digital Light Processing) (registered trademark) projection method or liquid crystal display devices using lamps or LEDs (Light Emitting Diode: Light Emitting Diode) as light sources, and each display has, for example, 1920 pixels in width , Vertical resolution of 1200 pixels. Multi-Display 5 as a whole is a screen size of 3840×2400 pixels.

[0037] The video signal processing device 6 is input with, f...

[0104] Next, a multi-display system according to the second embodiment will be described. In the first embodiment, when the video window layout is generated, it is controlled so that the video based on all the video signals input to the video signal processing device 6 is arranged on some displays. However, in the present embodiment, when the video window layout is generated, Select not all video windows (only part of the video windows) to be displayed. That is, a part of the video signals input to the video signal processing device 6 corresponds to all the videos to be displayed, and video windows corresponding to these videos are arranged on a part of the displays. However, the selected video window is a video window for displaying a video based on a video signal preselected for display in the low power consumption mode, for example. In addition, in the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numera...

[0115] Next, a multi-display system according to a third embodiment will be described. In the first embodiment, when the video window layout is generated, it is controlled so that videos based on all the video signals input to the video signal processing device 6 are arranged on some of the displays. Before the video window layout is generated, for example, before switching to the low power consumption mode, the video windows displayed on the multi-monitor are arranged on some of the monitors. That is, the videos displayed immediately before the generation of the video window layout correspond to all the videos to be displayed, and the video windows displaying these videos are arranged on some displays. In addition, in the third embodiment, the same components as those described in the first embodiment are assigned the same reference numerals and their descriptions are omitted.

[0116] In this embodiment, the Figure 8 In the layout generation process of the video window, i...

Abstract

Multi-display system. It is an object of the present invention to provide a multi-display system in which a video window necessary to display a video image can easily be displayed while the power consumption is suppressed. The multi-display system includes: a video window arrangement unit (9) that arranges and displays all the video windows, which should be displayed, only on some displays (1) in a multi-display (5) constructed by arraying a plurality of displays (1); and a power supply controlling unit (11) that controls power of the display (1) in which the video window is not displayed.

Description

technical field [0001] The present invention relates to a multi-display system formed by combining a plurality of displays. Background technique [0002] A multi-monitor system in which a plurality of monitors are arranged in a grid, for example, to form a single display screen (display) is widely used as a video display device for monitoring infrastructure fields such as electric power, transportation, and factory buildings. [0003] In addition, in such a multi-monitor system, in order to simultaneously display multiple videos on the display screen (display), a video signal processing device that displays multiple videos with arbitrary sizes, positions, and priorities is generally used. Select one or more videos and output them to the video display device. [0004] In recent years, as displays have become larger and brighter, and the power consumption of each display has increased, power saving in a multi-display system configured by combining a plurality of displays has ...
