  However, in the technique described in Patent Document 1, when an error occurs in the apparatus, it is not necessary to perform an input for connecting to the website, but information indicating the content and status of the error on the connected website. The user himself / herself has to perform the operation of inputting (for example, a serial number or an error code). For this reason, if it is a user with little knowledge about an apparatus, it is difficult to input information, and even if it can input, information may be input incorrectly. As described above, since the exact situation of the error is not reported to the manufacturer side through the website, the user may not be able to give an accurate instruction to deal with the error.

  Examples according to embodiments of the present invention will be described below.

  FIG. 1 is a diagram illustrating a schematic configuration of an error management system according to the present embodiment. As shown in FIG. 1, an error management system 1 includes a projector (image display device) 2 that projects an image onto a screen or the like, a portable communication terminal (communication terminal device) 3 that can be connected to the Internet, and a projector manufacturer. And a server 4 managed by the support center.

  First, the configuration of the projector 2 will be described. As shown in FIG. 2, the projector 2 includes a projection display unit (display unit) 20 that projects and displays an image displayed on the liquid crystal panel on a screen using a lamp and a projection lens, and an error detection that detects an error occurring inside the projector 2. Unit (detection unit) 21, a code generation unit (generation unit) 22 that generates a QR code (code image), and a control unit 23 that controls each of these components.

  In addition, when an error is detected by the error detection unit 21, the control unit 23 indicates an error status such as an error code corresponding to the content of the detected error, a serial number of the projector 2, a driving time, and the number of error occurrences. The information and the URL information (connection information) for accessing the product support site are transferred to the code generation unit 22 to generate a QR code (code image) representing the error information and the URL information. Then, the control unit 23 controls the projection display unit 20 to project and display an error warning screen including the error content and the generated QR code on the screen.

  Next, the configuration of the mobile communication terminal 3 will be described. As illustrated in FIG. 3, the mobile communication terminal 3 includes a digital camera unit (imaging unit) 30 that can capture an image of a subject, a wireless communication unit 31 that can be connected to the Internet through wireless communication, and a code process that decodes a QR code. A display panel 33 for displaying a confirmation image of the captured image, an operation switch 34 including various switches such as a number input switch, and a control unit 35 for controlling these components. Yes. That is, the mobile communication terminal 3 has a digital camera function and a communication function for connecting to the Internet. Therefore, when the user captures a QR code representing URL information using the digital camera function of the mobile communication terminal 3, the mobile communication terminal 3 acquires the URL information from the captured QR code, and displays the URL information on the website indicated by the URL information. It is possible to access. Specific examples of the mobile communication terminal 3 include a mobile phone, a PHS (Personal Handyphone System), and a PDA (Personal Digital Assistant).

  Next, processing when an error occurs in the projector 2 in the error management system 1 having the above-described configuration will be described with reference to the flowchart of FIG.

  For example, when an error occurring in the projector 2 is detected by the error detection unit 21 of the projector 2, the process of FIG. 4 is started. When the process is started, first, the projector 2 projects and displays an error warning screen (step S10). Here, the code generation unit 22 generates a QR code from error information and URL information of the detected error, and the control unit 23, as shown as an example in FIG. Then, a process of projecting and displaying the QR code 101 and the error warning screen 100 including the message 102 indicating that the support page can be accessed from the QR code 101 on the projection display unit 20 is performed.

  Next, the user uses the digital camera function of the mobile communication terminal 3 with the error warning screen 100 projected and displayed as a subject, so that the digital camera unit 30 captures an image of the QR code 101 (step S20). At this time, the code processing unit 32 decodes the QR code 101 included in the captured image, and acquires error information and URL information.

  Next, the control unit 35 of the mobile communication terminal 3 connects to the Internet via the wireless communication unit 31 and accesses the product support site corresponding to the acquired URL information (step S30). When the product support site is accessed, a support site input screen shown as an example in FIG. 6 is displayed on the display panel 33. The product support site input screen 200 includes an input field 201 for inputting a serial number, an input field 202 for inputting an error code, an input field 203 for inputting a driving time, and the like.

  Next, the control unit 35 of the mobile communication terminal 3 performs error information input processing on the input fields 201 to 203 of the input screen 200 (step S40). Thereby, the input process to the input field is automatically performed without the user manually inputting error information such as a serial number, an error code, and a driving time.

  Next, when the user confirms the input result displayed on the display panel 33 and performs an operation to transmit the input information, the mobile communication terminal 3 is input to the server 4 that operates the product support site. By transmitting the error information, an error report is made to the support center (step S50). Here, the server 4 that has received the report of the error information manages the error history of the projector 2 by registering the history of the reported error information in a predetermined database in order to use it for the after-sales service of the projector 2.

  Next, the server 4 that has received the report of the error information transmits the image information of the page describing the method for dealing with the error to the mobile communication terminal 3, and the control unit 35 performs an appropriate action for the error based on the received image information. Is displayed on the display panel 33 (step S60). When the user is instructed to deal with the error in the process of step S60, the process of FIG. 4 is terminated.

  According to the error management system 1 described above, the user images the projected error warning screen 100 using the digital camera function of the mobile communication terminal 3, so that the URL information and error information of the product support site can be obtained. It is possible to notify the server 4 of error information without manually inputting. Therefore, the user can report an error to the support center easily and in a short time. Further, since an appropriate instruction for the generated error is displayed on the display panel 33, even a user who is not familiar with the operation of the projector 2 can take an appropriate action for the generated error.

  The error information reported to the support center is obtained from the QR code, and is not manually input by the user. Therefore, accurate error information is reported to the server 4. As a result, the server 4 can issue an accurate instruction for the error.

  Although one example of the embodiment has been described above, the following modifications may be made.

  (Modification 1) In the case of the projector 2, when the lamp lighting time has reached the end of its life, an error report screen indicating that it is time to replace the lamp is projected and displayed, assuming that an error has occurred in the lamp. Good. When the mobile communication terminal 3 captures an error report screen and connects to the product support site indicated by the QR code 101, it connects to a page displaying the lamp purchase method, lamp replacement method, etc. along with a message prompting lamp replacement. It is good to do. In this way, the user can easily and smoothly obtain the replacement lamp and replace the lamp.

  (Modification 2) In the above embodiment, an example using a QR code has been described. However, the code image is not limited to this, and a two-dimensional code other than the QR code or a barcode may be used. Good. In addition, the mobile communication terminal 3 may have an OCR function, and the error warning screen 100 may display an image representing an error code or URL information with numerals or characters as a code image. In this case, the mobile communication terminal 3 can obtain an error code and URL information by performing OCR processing on the captured image, and can report an error to the support center.
