Problems solved by technology

In this case, although a projection display device such as an LED (Light Emitting Diode: Light Emitting Diode) is turned on to notify the user of the occurrence of the abnormality, if the user does not know the meaning of turning on the LED, the user may not be able to recognize the occurrence of the abnormality.
Also, in the technology described in Patent Document 1, the user who becomes the destination of the e-mail must be present at the site.
Also, in this technology, if the user holds a device that displays e-mails but does not pay attention to incoming e-mails, it is impossible to recognize the occurrence of an abnormality.

Embodiment approach

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0046] figure 1 It is a figure which shows the appearance of the display system 1 of embodiment. The display system 1 includes: a controller (master device) 10 , a slave device 20 , and a communication line 30 . The controller 10 and the slave device 20 are projection-type display devices (so-called projectors) that project and display images. The communication line 30 has connectors 310 and 320 at both ends, respectively. The connector 310 is connected to the controller 10 , and the connector 320 is connected to the slave device 20 . In this way, both the controller 10 and the slave device 20 are connected to the communication line 30 and can communicate with each other via the communication line 30 . In addition, the controller 10 and the slave device 20 are connected to a PC (Personal computer: a notebook type or a tablet type.) 2 via cables 40 and 50, respective...

Deformed example 1

[0087] The display system 1 includes two projectors in the above-mentioned embodiment, but may include three or more projectors. In this case, there is only one projector, that is, a controller that sends commands used for stack display, and all the remaining projectors become slaves. In this case, there are three methods for connecting the projectors via the communication line 30 .

[0088] Figure 13It is a diagram showing a method of connecting each projector in a display system including three projectors. Figure 13 (a) shows the case where the controller 10 and two slave devices 20 are connected in series. In this case, the projector in which the first type of abnormality occurs transmits abnormality data to the other two projectors directly or via the central slave device 20 . And, the 2 projectors receiving the abnormal data display Figure 9 or Figure 11 OSD image shown. The position where the OSD image is displayed is determined according to which projector the...

Deformed example 2

[0091] In the above-mentioned embodiment, the display system 1 performs stack display, but it may also display (referred to as tiling) images by a method called tiling in which images are displayed side by side. In the tile display, the controller 10 and the slave device 20 display different parts of the image when displaying the image together based on the data representing the image. In this case, the display system 1 displays an OSD image indicating that an abnormality has occurred in any one of the projectors by performing the abnormality notification process and the mutual notification process described in the embodiment. In the case of tiling, the displayed images do not overlap, or even if they overlap, only a small part of the end (if the width of the image is 100cm, about 1cm or 2cm of it) overlaps. Therefore, no matter where each projector displays an OSD image such as Figure 12 In the description of , when the third type of abnormality occurs, it does not occur th...

Abstract

A system displays an image using a plurality of projection type display devices, and is capable of reliably notifying a user who uses the system that an error has occurred in a certain projection type display device. A slave includes a display unit that projects and displays an image and a signal receiving unit that receives data transmitted from a commander. The slave includes a detection unit that detects an error in the commander on the basis of the receiving conditions of the data in the signal receiving unit. The slave includes a display control unit that, when an error is detected by the detection unit, makes the display unit display an image showing that the error has been detected.

Description

technical field [0001] The present invention relates to a technique for notifying a user of an abnormality in a system that displays images using a plurality of projection display devices. Background technique [0002] There is a technique for notifying a user of an abnormal occurrence in a projection type display device (so-called projector) that projects an image and displays the image on a screen or the like. Patent Document 1 describes a technique of sending an e-mail notifying a problem location to a system administrator or the like when a projector is considered to be abnormal. [0003] [Patent Document 1] JP-A-2004-13632 [0004] Here, there is a so-called stacking method of displaying one image brighter than a single projection display device by superimposing images displayed by a plurality of projection display devices. When displaying an image by this method, even if an abnormality occurs in a certain projection display device and the image is no longer displayed...
