The projection control unit 161 adjusts the display mode of the image in the image projection unit 50 and controls the projection of the image on the screen SC1.
Specifically, the projection control unit 161 controls the image processing unit 152 to execute image processing on the image data received by the communication unit 175. At this time, the projection control unit 161 may read the parameters necessary for the processing by the image processing unit 152 from the storage unit 170 and output them to the image processing unit 152.
Further, the projection control unit 161 controls the light source driving unit 121 to turn on the light source of the light source unit 55, and instructs the light source unit 55 on the brightness of the light source.

The correction processing unit 163 executes the correction process based on the state information output from the state detection unit 140.
For example, when the state information indicates the inclination of the projector 100A, the correction processing unit 163 instructs the image processing unit 152 to perform correction.
In addition, the correction processing unit 163 instructs the image processing unit 152 to perform correction based on the data regarding the distortion correction of the projection setting transmitted from the information processing apparatus 200.
The power supply unit 190 converts the electric power supplied from the external power supply 195 into a predetermined characteristic value and supplies it to each functional unit.

Further, part of the functions realized by software may be realized by hardware, or part of the functions realized by hardware may be realized by software.

FIG. 4 is a flowchart showing a processing flow (control method) of the projector setting program 250. Further, FIG. 5 is a flowchart showing details of the display tab change processing S310. In the following description, an example of the operation screen will be described with reference to FIGS. 6A to 6C and FIGS. 7A to 7C as appropriate.
In this embodiment, it is assumed that the projector setting program 250 is executed in the information processing apparatus 200 by the user's operation and the projectors (100A, 100B, 100C) to be set are designated. In this case, an operation screen (for example, FIGS. 7A to 7C) that functions as a user interface is created for each projector (100A, 100B, 100C) and can be switched by a tab that is one of the components that make up the user interface. It is displayed on the information processing device 200.

Note that, as shown in FIG. 6A or FIG. 7A, in the current state, the operation screen (first management screen) regarding the “projector A” indicating the projector 100A is displayed on the forefront, and the operable state (first Status) is assumed. Further, “projector B” indicates the projector 100B, and “projector C” indicates the projector 100C.
In this state, the control unit 220 determines whether or not the "Projector B" tab or the "Projector C" tab has been instructed by the user to instruct to change the operation screen (step S300). For example, when the "Projector B" tab is specified, the operation screen for "Projector B" is displayed in the foreground and is changed to the operable state (second state).

If it is determined that the change is instructed (Yes in step S300), the display tab change process S310 is executed.
Here, the processing of the display tab change processing S310 will be described with reference to FIG.
When the display tab changing process S310 is executed, first, the control unit 220 determines whether or not the operation screen is in the synchronization mode (step S312).
In the present embodiment, a selection switch (setting switch) displayed as “Synchronize” is arranged in the upper right portion of the operation screen, and the user selects the selection switch to switch ON / OFF of the synchronization mode. The selection switch displayed as "Synchronize" determines whether or not the item screens displaying the predetermined items are the same before and after the switching of the operation screens.

Here, as shown in FIG. 6A, when “Synchronize” is checked and it is determined that the operation screen is in the synchronization mode (Yes in step S312), the control unit 220 can currently operate “projector A”. The information of the operation screen of the tab is acquired (step S314). For example, in FIG. 6A, the control unit 220 acquires that the item screen indicating a predetermined item on the operation screen of the “projector A” is “focus / distortion correction”.
Next, the control unit 220 acquires information regarding the operation screen of the tab of the transfer destination to which the focus is transferred (step S316). For example, when the user selects the “projector B” tab, the control unit 220 acquires information regarding the operation screen of the “projector B” to which the focus shifts. Note that the acquired information includes the setting information of the item screen selected on the operation screen of the “projector B” when the operation screen of the “projector B” is displayed on the foreground and transitions to the operable state. included. In this case, the setting information indicates any of "focus / distortion correction", "zoom", "lens shift", and "test pattern".

Next, the control unit 220 compares the current operation screen of “projector A” with the operation screen when changed to “projector B”, and determines whether the two operation screens match, that is, “ As in “focus / distortion correction”, it is determined whether the item screens match or not (step S318).
Here, when it is determined that the two operation screens do not match (No in step S318), the control unit 220 displays the operation screen of the migration destination tab in accordance with the operation screen of the current tab (step S320). ), And ends step S310.

For example, as shown in FIG. 6A, the operation screen of “projector A” is the “focus / distortion correction” item screen (first item screen), and the transfer destination “projector B” item screen is “focus / distortion correction”. If it is a “lens shift” different from “,” the control unit 220 determines that the item screen of the “projector B” has an item corresponding to “focus / distortion correction” (in the present embodiment, “focus / distortion correction”). The setting information is changed so that it becomes the same item screen (second item screen) as that of ", and the operation screen of" projector B "is displayed in the foreground and transitioned to the operable second state. As a result, as shown in FIG. 6B, the operation screen (second management screen) of “projector B” whose item screen is “focus / distortion correction” is operably displayed.
In the present embodiment, the mode in which the item screens are the same has been described, but the present invention is not limited to this. It is sufficient if the functions of the item screens are the same. For example, the item screen of the operation screen of “projector B” has a different design from the item screen of “focus / distortion correction” on the operation screen of “projector A”, and items for which “focus / distortion correction” can be performed. It may be a screen.

In this embodiment, the item screen is assigned an address (URL: Uniform Resource Locator) on the website for each projector (100A, 100B, 100C), and the folder name is assigned the same file name for each item screen. Has been. For example, the folder name in the case of "focus / distortion correction" is "focus".
Therefore, the control unit 220 edits the URL corresponding to the current item screen of the “projector A” when changing the setting information so that the item screen of the “projector B” becomes “focus / distortion correction”. That is, by changing the folder name to "focus" and rewriting the path name of the projector 100A to the path name of the projector 100B, the item screen of the projector 100B can be set easily and quickly.

In the present embodiment, each item on the item screen to which the URL is assigned is assumed to have an initial state in which an initial value (default value) is set, but the present invention is not limited to this. For example, in “focus / distortion correction”, setting screens corresponding to a plurality of setting values in focus setting and distortion correction may be created, and URLs may be respectively assigned to the created setting screens. In this case, the control unit 220 may determine and display one of the plurality of setting screens based on the setting state set in the projector (100A, 100B, 100C).
When the user selects the “Projector C” tab, the control unit 220 changes the operation screen of the “Projector C” to the “focus / distortion correction” item screen as shown in FIG. Displayed on the screen and transition to the operable state.

On the other hand, when it is determined in step S318 that the two operation screens match (Yes), the control unit 220 displays the operation screen of the tab of the transfer destination (step S325), and ends step S310.
For example, when the current operation screen of "projector A" is the "focus / distortion correction" item screen as shown in FIG. 6A, the transfer destination "projector B" item screen is also the "focus / distortion correction" item screen. Therefore, it is displayed as shown in FIG. 6B. Similarly, since the item screen of the “projector C” of the transfer destination is also the item screen of “focus / distortion correction”, it is displayed as shown in FIG. 6C.

If it is determined in step S312 that the operation screen is not in the synchronous mode as shown in FIG. 7A (No), the control unit 220 displays the operation screen of the tab of the transfer destination (step S325), and ends step S310. To do.
In this case, even if the current operation screen of the "projector A" is the "focus / distortion correction" item screen as shown in FIG. 6A, the transfer destination "projector B" item screen is as shown in FIG. 7B. , The "lens shift" item screen is displayed based on the setting information. Similarly, the item screen of the "projector C" of the transfer destination is the item screen of the "test pattern" based on the setting information, as shown in FIG. 7C.

  As described above, when changing the operable operation screen in synchronization with the projector 100A from the projector 100A, the control unit 220 selects on the operation screen of the projector 100A when the projector 100A is in the operable state. The control is performed so that the item corresponding to the predetermined item that has been displayed is also displayed on the operation screen of the projector 100B. That is, when the first item screen is operably selected on the operation screen of the projector 100A, the control unit 220 displays the second item screen having the same items as the first item screen on the operation screen of the projector 100B. Is operably selected and displayed.

If it is determined that the setting of the operation screen has not been changed (No in step S330), the process proceeds to step S350.
In step S350, the control unit 220 determines whether or not the end is instructed, and when it is determined that the end is instructed (Yes), ends the process.
On the other hand, if it is determined that the end is not instructed (No in step S350), the process returns to the beginning (step S300) of the process of the projector setting program 250, and the above process is repeated.

According to the embodiment described above, the following effects are achieved.
(1) When a user operates to switch from a first state in which the operation screen of “projector A” is operable to a second state in which the operation screen of “projector B” is operable, the second state In, the operation screen of "projector B" in which the item screen corresponding to the item screen selected in the operation screen of "projector A" in the first state is selected is displayed. Therefore, since the item screen corresponding to the item screen selected on the operation screen of the “projector A” is selected on the operation screen of the “projector B”, the predetermined items of the projector 100A and the projector 100B are The management can be performed quickly, and the convenience of managing the projectors 100A and 100B is improved.

  (2) When the first state in which the operation screen of “projector A” can be operated is switched to the second state in which the operation screen of “projector B” can be operated, in the second state, in the first state, The operation screen of "projector B" in which the same item screen as the item screen selected in the operation screen of "projector A" is selected is displayed. Therefore, when the projectors 100A and 100B to be managed are switched, the same operation screen is displayed, which saves the trouble of selecting the operation screen every time the projectors 100A and 100B are switched.

  (3) When the first state in which the operation screen of "projector A" is operable is switched to the second state in which the operation screen of "projector B" is operable, "projector B" is selected according to the selection switch. The operation screen of "Projector A" can be changed to the same item screen as the operation screen of "Projector A" and displayed, or the item screen selected on the operation screen of "Projector B" can be displayed without change.
