  The interrupt connection is a function in which another device (for example, another PC 2 or PC 3) connected to the network 5 connects to the projector 100 when the PC 2 is connected to the projector 100. When the check box of the “prohibit interrupt connection” item in the additional setting unit 207 is checked, interrupt connection is prohibited for the connection between the projector 100 and the PC 2. When the projector 100 and the PC 2 are connected in this state, the projector 100 and / or the PC 2 refuses an interrupt connection by another device. The multi-display is a function in which the projector 100 projects the screens that the projector 100 connects to the plurality of PCs 2 and 3 and the plurality of PCs 2 and 3 transmit to the projector 100 at the same time. When the check box of the “use of multi-display” item is checked in the additional setting unit 207, the projector 100 is in a state where it can be connected to another PC after connecting to the PC 2. When another PC is connected, the projector 100 displays a multi-display.

  An option setting button 208 is arranged on the search result screen 201. In response to the operation of the option setting button 208, the setting execution unit 24 causes the display control unit 27 to display the option setting screen 211.

In the option setting screen 211 in FIG. 3B, setting display portions 212 and 214 for displaying a list of setting items, a check box 213 for specifying whether or not each setting item is necessary, and a radio button 215 are arranged.
The host user can perform settings for various items by performing an operation of checking or unchecking the check box 213 or selecting the radio button 215 by the input unit 26.
In the example of FIG. 3B, the setting display unit 212 is set to determine whether to use full-screen video transfer between the PC 2 and the projector 100, whether to perform encrypted communication, and at startup. You can set whether to display the connection mode selection screen. The availability of each setting item is set by a check box 213.
The setting display unit 214 can select one of three setting items for a search method at the time of searching for the projector 100 when the PC 2 is started. Specifically, a setting for performing an automatic search when the PC 2 is started, a setting for specifying a search method by the operation of the host user after the startup, or a setting for searching for the projector 100 with the previously used network settings can be selected. From these three settings, the host user uses the radio button 215 to select one.

  The option setting screen 211 includes a plurality of tabs. FIG. 3B shows a “general setting” tab. In addition to the “General Settings” tab, a “Performance Adjustment” tab and an “Audio Output” tab can be used. When the “Performance Adjustment” tab is opened, the host user can set the balance between the display quality and the processing speed in the projector 100, and when the “Audio Output” tab is opened, the user can make settings related to the audio output by the projector 100. Can do.

  In the operation of displaying the search result screen 201 and the option setting screen 211 and performing the setting, the setting execution unit 24 may use the function of the web browser 22. That is, even if the web browser 22 accesses the projector 100 to download the web page data for setting, the search control screen 27 displays the search result screen 201 and the option setting screen 211 based on the web page for setting. Good.

The setting execution unit 24 acquires the contents set by the operation of the host user on the search result screen 201 and the option setting screen 211, and generates the function setting data 142 or the function setting data 143 corresponding to the set contents. .
The function setting data 142 and 143 include, for example, data indicating items displayed on the additional setting unit 207 and flags indicating whether or not each item is checked in a check box. For example, the function setting data 142 and 143 include data indicating items displayed on the setting display unit 212 and flags indicating whether or not there is a check in the check box 213 of each item in association with each other. Further, for example, the function setting data 142 and 143 include data indicating the setting selected by the radio button 215 among the items displayed on the setting display unit 214.

The function setting data 142 is data related to settings when the PCs 2A and 3A of the solution A are connected to the projector 100. The function setting data 143 is data related to settings when the PCs 2B and 3B of the solution B are connected to the projector 100. Accordingly, when the setting is performed on the search result screen 201 and the option setting screen 211 by the operation of the host user on the PC 2A, the setting execution unit 24 of the PC 2A generates the function setting data 142. Then, the PC 2A transmits the generated function setting data 142 to the projector 100 and stores it in the storage unit 140. Here, the setting execution unit 24 may store the generated function setting data 142 in the storage unit 30.
Further, when the setting is performed on the search result screen 201 and the option setting screen 211 by the operation of the host user on the PC 2B, the setting execution unit 24 of the PC 2B generates the function setting data 143. The PC 2B transmits the generated function setting data 143 to the projector 100 and stores it in the storage unit 140. Here, the setting execution unit 24 may store the generated function setting data 143 in the storage unit 30.

  Further, the setting execution unit 24 performs processing for adding information that can refer to the connection setting data 144 to the function setting data 142 and 143 when the function setting data 142 and the function setting data 143 are generated. That is, the setting execution unit 24 of the PC 2A generates function setting data 142 having information that can refer to the connection setting data 144, and the setting execution unit 24 of the PC 2B has a function setting having information that can refer to the connection setting data 144. Data 143 is generated.

The information that can refer to the connection setting data 144 includes information that identifies the connection setting data 144 stored in the storage unit 140. For example, the file path of the connection setting data 144 in the storage unit 140 of the projector 100 or the like. This information may be embedded in the function setting data 142 and 143, or may be added as metadata of the function setting data 142 and 143.
Thereby, for example, when the PC 3A refers to the function setting data 142 stored in the storage unit 140, the information (file path or the like) added to the function setting data 142 can be referred to. Since the PC 3A can refer to and acquire the connection setting data 144 stored in the storage unit 140 in accordance with the referenced file path or the like, the setting using the connection setting data 144 can be performed. The setting by the connection setting data 144 can be performed before performing the function setting based on the function setting data 142.

  The same applies to the function setting data 143. When the PC 3B refers to the function setting data 143 stored in the storage unit 140, the above information (file path or the like) added to the function setting data 143 can be referred to. The PC 3B can refer to the connection setting data 144 stored in the storage unit 140 in accordance with the referenced file path or the like, obtain the information, and perform settings using the connection setting data 144.

  The image data transmission / reception unit 25 executes processing for transmitting image data when the PC 2 is connected to the projector 100 and transmits image data to the projector 100. The image data transmission / reception unit 25 controls the communication unit 28 to read out the image data 35 stored in the storage unit 30 and transmit it to the projector 100. The image data transmission / reception unit 25 converts the data format, resolution, frame rate, and the like of the image data 35 into a mode suitable for the purpose of transmission to the projector 100, and transmits the data by the communication unit 28. May be.

Similarly to the PC 2, the PC 3 includes a control unit 20 </ b> A, an input unit 26, a display control unit 27, a communication unit 28, and a storage unit 30, and these units are connected to a bus 29. The configuration of PC3 in FIG. 2B is common to PC3A and PC3B.
Similar to the control unit 20, the control unit 20A includes a processor such as a CPU, a nonvolatile ROM, and a RAM that forms a temporary storage area. The processor of the control unit 20A controls the PC 3 by executing a basic control program stored in the ROM. In this case, the processor of the control unit 20A corresponds to a computer that controls the PC 3 by executing a program.

  In the PC 3, the configuration of the input unit 26, the display control unit 27, the communication unit 28, and the storage unit 30 is the same as that of the PC 2.

  The processor of the control unit 20A functions as an operating system 21, a web browser 22, a message processing unit 23, a setting execution unit 24A, and an image data transmission / reception unit 25 by executing various programs stored in the storage unit 30. Among these, the functions of the operating system 21, the web browser 22, the message processing unit 23, and the image data transmission / reception unit 25 are the same as those of the PC 2.

  The web browser 22 of the PC 3 accesses the projector 100 based on the URL specified by an operation on the input unit 26 and downloads the function setting data 142 or the function setting data 143 stored in the projector 100. The setting execution unit 24 </ b> A performs settings related to processing contents or functions executed with the projector 100 based on the function setting data 142 or the function setting data 143 downloaded by the web browser 22.

  For example, the web browser 22 of the PC 3A downloads the function setting data 142 from the projector 100, and the setting execution unit 24A refers to the downloaded function setting data 142. Here, the setting execution unit 24A acquires the connection setting data 144 stored in the projector 100 based on information (such as a path) included in the function setting data 142. The setting execution unit 24 </ b> A performs settings for executing communication with the projector 100 based on the connection setting data 144. Thereafter, the setting execution unit 24A performs function setting based on the function setting data 142. The image data transmission / reception unit 25 transmits the image data 35 to the projector 100 according to the setting by the setting execution unit 24A, and causes the projector 100 to display an image. The PC 3B downloads the function setting data 143, and thereafter performs the same processing as the PC 3A.

  The message processing unit 23 of the PC 3 receives the message transmitted from the PC 2 and causes the display control unit 27 to display it. Here, the PC 3 can select information such as a URL included in the displayed message by operating the input unit 26. In this case, the web browser 22 accesses the projector 100 based on information such as the selected URL. Therefore, when the PC 2A transmits a message including a URL for accessing the function setting data 142 to the PC 3A, the function setting data 142 can be downloaded quickly by the web browser 22 of the PC 3A. When the PC 2B transmits a message including the URL of the function setting data 143 to the PC 3B, the web browser 22 of the PC 3B can download the function setting data 143. In this case, the guest user who operates the PCs 3A and 3B can access the function setting data 142 and 143 without inputting the URL.

  The image data transmission / reception unit 25 included in the PC 2 and the image data transmission / reception unit 25 included in the PC 3 receive the image data transmitted by the projector 100 and store them in the storage unit 30. The control unit 20 causes the display control unit 27 to display the image data stored in the storage unit 30 according to the operation of the input unit 26, or transmits the image data to the projector 100 for projection.

The communication unit 146 transmits and receives data via the network 5 under the control of the control unit 130. The communication unit 146 outputs the data received from the network 5 to the control unit 130. When the communication unit 146 receives the image data from the PCs 2 and 3, the control unit 130 outputs the received image data to the image processing unit 149 and causes the projection unit 110 to project an image based on the image data.

  The control unit 130 includes a CPU, a RAM, a ROM, and the like (not shown), and controls each unit of the projector 100 by executing a control program stored in the ROM or the storage unit 140. The control unit 130 functions as a projection control unit 131, a communication control unit 132, a setting data control unit 133, and an imaging control unit 134 by executing a control program. The processing performed by these blocks will be described later. In this case, the CPU of the control unit 130 corresponds to a computer that executes the program and controls the projector 100.

  The storage unit 140 includes a magnetic storage medium and a semiconductor storage element, and is a nonvolatile storage device that stores programs and data. The storage unit 140 stores a control program executed by the control unit 130 and data processed by the control unit 130 in a nonvolatile manner. The storage unit 140 stores a connection program 141, function setting data 142, function setting data 143, and connection setting data 144. The connection program 141 is a program executed by the PCs 2 and 3, stored in advance in the storage unit 140, and downloaded according to the access of the PCs 2 and 3. The function setting data 142 and 143 are generated by the PC 2 as described above and stored in the storage unit 140. The connection setting data 144 includes, for example, the IP address of the projector 100 and is stored in the storage unit 140 in advance.

The image processing unit 149 processes image data input from the image supply device (not shown) to the image input unit 145 or image data received by the communication unit 146 from the PCs 2 and 3 under the control of the control unit 130. The processing executed by the image processing unit 149 is, for example, processing such as scaling, resizing, geometric correction, enlargement / reduction, color tone correction, and luminance correction. The image processing unit 149 executes processing designated by the control unit 130 and performs processing using parameters input from the control unit 130 as necessary. Of course, it is also possible to execute a combination of a plurality of processes.
The image processing unit 149 expands the processed image data in the frame memory 148. The image processing unit 149 outputs display image data to the light modulation device driving unit 122 based on the image data developed in the frame memory 148.

  The light modulation device driving unit 122 is connected to the liquid crystal panel of the light modulation device 112. The light modulation device driving unit 122 generates R, G, and B image signals based on the display image data input from the image processing unit 149, and drives the liquid crystal panels based on the generated image signals to each liquid crystal panel. Draw an image.

  The projection control unit 131 (display control unit) controls each unit of the projector 100 to execute image projection onto the screen SC. The projection control unit 131 controls the image processing unit 149 to execute processing on the image data. Here, the projection control unit 131 may read out parameters necessary for processing executed by the image processing unit 149 from the storage unit 140 and output the parameters to the image processing unit 149. In addition, the projection control unit 131 controls the light source driving unit 121 to turn on the light source 111 and adjust the luminance of the light source 111. As a result, the light source 111 emits light, and the image light modulated by the light modulation device 112 is projected onto the screen SC by the projection optical system 113.

  The communication control unit 132 controls the communication unit 146 to execute data communication. In addition, when there is an access requesting setting by the setting execution unit 24 of the PC 2 connected via the network 5, the communication control unit 132 responds to this access.

The setting data control unit 133 controls data related to settings in the PCs 2 and 3 and the projector 100 by transmitting and receiving data to and from the PCs 2 and 3 via the communication unit 146. The setting data control unit 133 receives the function setting data 142 or the function setting data 143 transmitted from the PC 2 and stores it in the storage unit 140.
When the web browser 22 of the PC 2 or 3 requests the function setting data 142 or 143 or the connection setting data 144, the setting data control unit 133 sends the function setting data 142 or 143 or the connection setting data 144 in response to this request. Send.

The imaging range (view angle) of the camera 154 includes part or all of the image projection range in which the projection optical system 113 projects an image onto the screen SC. For example, the projector 100 can capture a projected image on the screen SC with the camera 154 when the projector 100 projects an image based on image data input to the image input unit 145 from an image supply device (not shown).

  The imaging control unit 134 causes the camera 154 to perform imaging at a timing requested from the PCs 2 and 3 and an image supply device (not shown), a preset timing, or a timing specified by an operation of the projector 100. The imaging control unit 134 transmits the captured image data of the camera 154 to the PCs 2 and 3 through the communication unit 146. Here, the imaging control unit 134 transmits the captured image data to the PCs 2 and 3 that are set in advance as counterparts to which images are transmitted by the function setting data 142 and 143.

  FIG. 5 is a flowchart showing the operation of the display system 1 and shows a setting method related to setting of functions in the display system 1. FIG. 5A shows the operation of the PC 3, (B) shows the operation of the PC 2, and (C) shows the operation of the projector 100. In FIG. 5, the operations of the PCs 2A and 3A belonging to the solution A are shown as an example, but the PCs 2B and 3B belonging to the solution B can also operate similarly.

  The host user operates the PC 2A to input for setting (step S11), and input information for connection to connect to the projector 100 (step S12). Information for connection may be input in a plurality of stages. That is, the control unit 20 of the PC 2A searches for the projector 100 and displays the search result screen 201 of FIG. Subsequently, when an input for selecting the projector 100 is performed on the search result screen 201, the PC 2A connects to the projector 100 in response to this input. The input before and after the display of the search result screen 201 corresponds to the input of connection information in step S12.

  The PC 2A accesses the projector 100 according to the input information (step S13), and the PC 2A and the projector 100 are connected so as to be capable of data communication with each other (steps S13 and S21). In this state, for example, the PC 2A displays the option setting screen 211.

The PC 2A executes setting according to the operation of the input unit 26, generates function setting data 142, and transmits the function setting data 142 to the projector 100 (step S14). The projector 100 receives the function setting data 142 transmitted from the PC 2A and stores it in the storage unit 140 (step S22).
The PC 2A acquires acquisition information for accessing the function setting data 142 stored in the storage unit 140 (step S15). The acquisition information is information necessary for the PC 3A to refer to the function setting data 142 via the network 5. Specifically, information for specifying the projector 100 in the network 5 and specifying the function setting data 142 among the data stored in the projector 100 (for example, the file path and file name of the function setting data 142 in the storage unit 140). including. When the projector 100 has a file server function and a web server function, the acquisition information acquired by the PC 2A can be a URL.

  In accordance with the operation of the input unit 26, the PC 2A generates a message including the URL that is the acquisition information acquired in step S16 by the function of the message processing unit 23, and transmits the message to the PC 3A (step S16).

The PC 3A receives a message from the PC 2A by the function of the message processing unit 23, and displays the content of the received message on the display control unit 27 (step S31).
Here, the guest user who operates the PC 3A operates the input unit 26 to input to instruct access to the URL included in the message (step S32). In accordance with the input, the PC 3A accesses the function setting data 142 stored in the projector 100 based on the URL included in the message (step S33). The projector 100 receives access from the PC 3A (step S23) and transmits the function setting data 142 (step S24). The PC 3A receives the function setting data 142 from the projector 100 (step S34). The PC 3A requests the connection setting data 144 from the projector 100 in accordance with information (such as a path of the connection setting data 144) included in the received function setting data 142 (step S35).

The projector 100 receives the request from the PC 3A (step S25) and transmits the connection setting data 144 to the PC 3A (step S26).
The PC 3A receives the connection setting data 144 transmitted from the projector 100 (step S36). The PC 3A performs settings for communicating with the projector 100 according to the connection setting data 144, and performs function settings according to the function setting data 142 (step S37).

With the operation illustrated in FIG. 5, the PC 2A and the PC 3A can perform settings related to data communication with the projector 100, and can perform communication according to the settings. Further, the PC 2B and PC 3B belonging to the solution B can execute the same operation.
A function in which the guest user operating the PC 3A reflects the contents set by the host user operating the PC 2A only by specifying the acquisition information (for example, URL) included in the message transmitted from the PC 2A. Settings can be made.

  Further, the projector 100 stores function setting data 142 corresponding to the solution A and function setting data 143 corresponding to the solution B in the storage unit 140. In this state, the PC 3A can acquire and set the function setting data 142 corresponding to the PC 3A according to the operation of the guest user. Thus, the guest user can select and acquire appropriate function setting data from a plurality of function setting data by a simple operation. Accordingly, in an environment in which a plurality of groups (solutions) of PCs having different setting contents access the projector 100, an incorrect setting is not performed and a reliable setting can be performed.

  Further, the PC 3 obtains and refers to the connection setting data 144 based on information included in the function setting data 142 and 143, and performs settings related to communication with the projector 100. Thereby, the setting using the connection setting data 144 and the function setting using the function setting data 142 and 143 can be executed according to a small number of operations. Accordingly, the burden on the guest user who operates the PC 3 can be further reduced, and the projector 100 can be used using the PC 3 even for a user with a low level of proficiency.

  In the display system 1, the connection setting data 144 that is information necessary for connecting the PCs 2 and 3 to the projector 100 and the function setting data 142 and 143 that are information related to function settings are separated into the storage unit 140. Remember. Thereby, when the display system 1 comprises a plurality of solutions (solutions A and B), information different for each solution and information common to the plurality of solutions can be managed efficiently. Therefore, it is possible to improve management efficiency when a plurality of solutions are set in the display system 1.

  In the setting method shown in FIG. 5, the function setting data 142 and 143 stored in the storage unit 140 may be erased or discarded under the control of the PCs 2 </ b> A and 2 </ b> B or the projector 100. For example, the projector 100 may delete the function setting data 142 and 143 when a preset time elapses after the PCs 2A and 2B generate the function setting data 142 and 143. Further, for example, when a preset time elapses after the PCs 2A and 2B generate the function setting data 142 and 143, the PCs 2A and 2B request the projector 100 to delete the function setting data 142 and 143. May be. For example, when the PC 2A generates the function setting data 142, the function setting data 142 generated before that may be deleted.
