[0044] When image data is input, the projector 10 determines in step S103 whether the mode information is a screen display mode. The mode information is a screen display mode or a screen non-display mode. The mode information is set in advance before the image data is input. The mode information is stored in the memory 17. In the initial setting, the screen display mode is set in the projector 10 in advance. The initial setting is a setting that is set when the projector 10 is shipped from the factory or when the projector 10 is reset.

[0045] When the OSD control unit 23 determines that the mode information is the screen display mode, it proceeds to step S105 (step S103: YES). When the OSD control unit 23 determines that the mode information is not the screen display mode, it determines that the mode information is the screen non-display mode. When the OSD control unit 23 determines that the mode information is the screen non-display mode, it proceeds to step S131 (step S103: NO).

[0046] When the projector 10 determines in step S103 that the mode information is the screen non-display mode, it acquires a standard setting value group in step S131. The OSD control unit 23 reads out the standard setting value group from the memory 17. The memory 17 stores the standard setting value group in advance. The OSD control unit 23 outputs the standard setting value group to the image control unit 25 as a setting value group.

[0056] The unset icon 101f is an icon for which a scene type can be set by an administrator of the projector 10. The unset icon 101f becomes selectable when the administrator has made a predetermined setting for the unset icon 101f. The unset icon 101f indicates that it cannot be selected by the user of the projector 10.

[0057] The first scene setting screen 100a displays a display setting field 103. The display setting field 103 accepts a switching operation input for switching from a screen display mode to a screen non-display mode. When the first scene setting screen 100a is displayed, the screen non-display mode can be set. The display setting field 103 shown in FIG. 5 shows a state in which a switching operation input is not being accepted. When a switching operation input is accepted in the display setting field 103, the display mode of the display setting field 103 is changed. As an example, a check image is displayed superimposed in the display setting field 103. The display setting field 103 corresponds to an example of a switching input field. The switching operation input corresponds to an example of switching input information.

The OSD control unit 23 transmits detail setting screen data to the projection unit 30. The OSD control unit 23 causes the detail setting screen 110 to be projected onto the projection surface SC based on the detail setting screen data. The OSD control unit 23 causes the projection unit 30 to project the detail setting screen 110, thereby displaying the detail setting screen 110 on the projection surface SC. The displayed detail setting screen 110 is the first detail setting screen 110a shown in FIG. 6 or the like.

[0106] After displaying the detailed setting screen 110, the projector 10 accepts a setting value corresponding to the setting icon 111 in step S213. The user performs an operation input for one of the multiple setting icons 111 included in the detailed setting screen 110. The OSD control unit 23 accepts the operation input for the one setting icon 111. When the one setting icon 111 is selected, the user can change the initial setting value of the setting item corresponding to the one setting icon 111 to another setting value. When the user changes to another setting value, the OSD control unit 23 acquires the changed setting value as the setting value of the setting item. When the user does not change the initial setting value, the OSD control unit 23 acquires the initial setting value as the setting value of the setting item.

[0107] When the user performs an operation input using the enter button, which is one of the input buttons 13 included in the operation panel 11, the OSD control unit 23 acquires the setting value of the setting item corresponding to the setting icon 111. When the user changes the setting values of the setting items corresponding to multiple setting icons 111, the OSD control unit 23 acquires a setting value group that is a set of setting values for the multiple setting items. The OSD control unit 23 outputs the acquired setting value group to the image control unit 25.

[0108] After receiving the setting values, the projector 10 corrects the image data and displays the corrected corrected image data in step S215. The image control unit 25 acquires a set of setting values from the OSD control unit 23. The image control unit 25 corrects the image data using the set of setting values. The image control unit 25 outputs the corrected image data to the projection unit 30 as corrected image data. The projection unit 30 projects a projection image PG onto the projection surface SC based on the corrected image data. The image control unit 25 causes the projection unit 30 to project based on the corrected image data, thereby displaying the projection image PG on the projection surface SC.

[0109] 9, after the mode information is stored in step S209, the detailed setting screen 110 is displayed in step S211, but this is not limiting. When the OSD control unit 23 receives a selection input for the selection icon 101, it may obtain a group of initial setting values corresponding to the selected scene type and output the group of initial setting values to the image control unit 25. The image control unit 25 corrects the image data using the obtained group of initial setting values. The image control unit 25 causes the projection unit 30 to project the projection image PG based on the corrected image data.

[0110] When the projector 10 determines in step S203 that the mode information is the screen non-display mode, it proceeds to step S221 (step S203: NO). When the projector 10 determines in step S211 whether or not automatic scene setting is applied. When the control unit 21 determines that automatic scene setting is stored in the memory 17, it proceeds to step S223 (step S221: set). When the control unit 21 determines that automatic scene setting is not stored in the memory 17, it proceeds to step S231 (step S221: not set).

[0111] In step S223, the projector 10 determines the scene type of the image data. The control unit 21 analyzes the image data to determine the scene type based on the image data. The control unit 21 analyzes image patterns and the like included in the image data to determine the scene type. The scene types are games, movies, presentations, multi-screens, and the like. The scene types correspond to examples of image types.

[0112] After determining the scene type, the projector 10 acquires a set value group in step S225. The OSD control unit 23 acquires a set of initial setting values set for each scene type stored in the memory 17. The memory 17 stores a set of initial setting values corresponding to the scene type. The memory 17 stores a set of initial setting values corresponding to game scenes, a set of initial setting values corresponding to movie scenes, etc. The OSD control unit 23 acquires the set of initial setting values and outputs the set of initial setting values to the image control unit 25 as a set of setting values. The projector 10 proceeds to step S215.

[0113] When the projector 10 determines in step S221 that the scene is not automatic setting, the projector 10 proceeds to step S231 (step S221: Not set). In step S231, the projector 10 acquires a group of standard setting values. The OSD control unit 23 reads out the group of standard setting values from the memory 17. The OSD control unit 23 outputs the group of standard setting values to the image control unit 25 as a group of setting values. The projector 10 proceeds to step S215.

[0114] The second scene setting screen 100b has an automatic selection field 105 for switching whether to apply automatic scene setting that automatically adjusts the projected image PG displayed based on image data. The display method includes accepting a change input entered in the automatic selection field 105 when the second scene setting screen 100b is displayed, and switching the screen display mode to a screen non-display mode when the change input indicates that the automatic scene setting is to be applied. When the automatic scene setting is applied, the second scene setting screen 100b is not displayed. When the automatic scene setting is applied, the user does not need to view the second scene setting screen 100b.

[0115] The display method further includes determining a scene type based on the image data when the image data is input and it is determined that the scene is automatically set. When automatic scene setting is applied, the scene type is determined based on the image data, so that a set of setting values corresponding to the scene type can be set.

[0116] Third embodiment The third embodiment shows a display method different from the first and second embodiments. The third embodiment shows a display method of the projector 10 that associates and stores external device information 19 of the image providing device 50 with mode information. The external device information 19 corresponds to the device-specific information 53 of the image providing device 50. FIG. 10 shows a flowchart relating to the display method of the projector 10. FIG. 10 shows a display method of the projector 10 that associates and stores external device information 19 of the image providing device 50 with mode information.

[0117] In step S301, the projector 10 inputs image data and device-specific information 53 from the image providing device 50. The communication interface 15 of the projector 10 is connected for communication with the communication unit 57 of the image providing device 50. The communication interface 15 inputs the image data and device-specific information 53 from the communication unit 57. The device-specific information 53 is added to the image data and output from the image providing device 50. When the image providing device 50 is connected for communication with the projector 10, it may output the device-specific information 53 to the projector 10 separately from the image data. The communication interface 15 outputs the image data to the OSD control unit 23 of the control unit 21. The OSD control unit 23 inputs the image data.

[0118] After inputting the image data and the device-specific information 53, the projector 10 determines in step S302 whether the external device information 19 corresponding to the device-specific information 53 is stored in the memory 17. The memory 17 stores the external device information 19 in association with mode information. The memory 17 stores the external device information 19 in association with a screen display mode. Alternatively, the memory 17 stores the external device information 19 in association with a screen non-display mode. When the communication interface 15 inputs the device-specific information 53, the memory 17 stores the external device information 19 as information corresponding to the device-specific information 53. When the image providing device 50 outputs image data to the projector 10 for the first time, the memory 17 stores the external device information 19 corresponding to the device-specific information 53 in association with the initial screen display mode. When a user sets the screen non-display mode using the scene setting screen 100, the memory 17 stores the device specific information 53 of the image providing device 50 that output the image data, the corresponding external device information 19, and the screen non-display mode in association with each other.

[0119] The OSD control unit 23 determines whether the external device information 19 corresponding to the device-specific information 53 is stored in the memory 17. If the memory 17 does not store the external device information 19, the OSD control unit 23 proceeds to step S305 (step S302: NO). When the image providing device 50 outputs image data to the projector 10 for the first time, the memory 17 does not store the external device information 19 corresponding to the device-specific information 53. After the memory 17 stores the external device information 19 in association with the screen display mode, the projector 10 proceeds to step S305. If the memory 17 stores the external device information 19 corresponding to the device-specific information 53, the OSD control unit 23 proceeds to step S303 (step S302: YES).

[0120] When the projector 10 determines that the external device information 19 is stored, it determines in step S303 whether the mode information associated with the external device information 19 is the screen display mode. Once the image providing device 50 connects to the projector 10, the external device information 19 corresponding to the device-specific information 53 is stored in the memory 17. When the OSD control unit 23 determines that the memory 17 stores the external device information 19 in association with the screen display mode, it proceeds to step S305 (step S303: YES). When the OSD control unit 23 determines that the memory 17 stores the external device information 19 in association with the screen non-display mode, it proceeds to step S331 (step S303: NO). When the OSD control unit 23 proceeds to step S331, it does not display the first scene setting screen 100a.

[0121] When the projector 10 determines in step S303 that the mode information is the screen non-display mode, it acquires a standard setting value group in step S331. The OSD control unit 23 reads out the standard setting value group from the memory 17. The OSD control unit 23 outputs the standard setting value group to the image control unit 25 as a setting value group. The projector 10 proceeds to step S315.

[0122] In step S305, the projector 10 displays the first scene setting screen 100a. The OSD control unit 23 causes the projection unit 30 to project the first scene setting screen 100a on the projection surface SC based on the scene setting screen data. The projection unit 30 projects the first scene setting screen 100a on the projection surface SC under the control of the OSD control unit 23. Although the projector 10 displays the first scene setting screen 100a in step S305, this is not limiting. The projector 10 may also display the second scene setting screen 100b.

[0123] After displaying the first scene setting screen 100a, the projector 10 accepts a selection input by the user in step S307. The user performs the selection input by operating the input button 13 on the operation panel 11. A selection input for one of the multiple selection icons 101 displayed on the first scene setting screen 100a shown in FIG. 5 is accepted. A switching operation input by the user may also be accepted for the display setting field 103.

[0124] When the projector 10 receives a selection input to the selection icon 101, in step S309, the projector 10 receives the scene type corresponding to the selection icon 101 received on the first scene setting screen 100a. The OSD control unit 23 receives the scene type corresponding to the selection icon 101. The OSD control unit 23 temporarily stores the scene type corresponding to the selection icon 101. The OSD control unit 23 may store the scene type corresponding to the selection icon 101 in the memory 17.

[0125] When the projector 10 receives a switching operation input to the display setting field 103, in step S309, it switches from the screen display mode to the screen non-display mode. The OSD control unit 23 stores the screen non-display mode in the memory 17 as mode information based on the switching operation input.

[0126] After storing the scene type corresponding to the selection icon 101, the projector 10 displays the detail setting screen 110 in step S311. The OSD control unit 23 transmits detail setting screen data to the projection unit 30. The OSD control unit 23 causes the detail setting screen 110 to be projected onto the projection surface SC based on the detail setting screen data. The OSD control unit 23 causes the projection unit 30 to project the detail setting screen 110, thereby displaying the detail setting screen 110 on the projection surface SC.

[0127] After displaying the detailed setting screen 110, the projector 10 accepts a setting value corresponding to the setting icon 111 in step S313. The user performs an operation input for one of the multiple setting icons 111 included in the detailed setting screen 110. The OSD control unit 23 accepts the operation input for the one setting icon 111. When the one setting icon 111 is selected, the user can change the initial setting value of the setting item corresponding to the one setting icon 111 to another setting value. When the user changes to another setting value, the OSD control unit 23 acquires the changed setting value as the setting value of the setting item. When the user does not change the initial setting value, the OSD control unit 23 acquires the initial setting value as the setting value of the setting item.

[0128] When the user performs an operation input using the enter button, which is one of the input buttons 13 included in the operation panel 11, the OSD control unit 23 acquires the setting value of the setting item corresponding to the setting icon 111. When the user changes the setting values of the setting items corresponding to multiple setting icons 111, the OSD control unit 23 acquires a setting value group that is a set of setting values for the multiple setting items. The OSD control unit 23 outputs the acquired setting value group to the image control unit 25.

[0129] After receiving the setting values, the projector 10 corrects the image data and displays the corrected corrected image data in step S315. The image control unit 25 acquires a set of setting values from the OSD control unit 23. The image control unit 25 corrects the image data using the set of setting values. The image control unit 25 outputs the corrected image data to the projection unit 30 as corrected image data. The projection unit 30 projects a projection image PG onto the projection surface SC based on the corrected image data. The image control unit 25 causes the projection unit 30 to project based on the corrected image data, thereby displaying the projection image PG on the projection surface SC.

[0130] 10 shows that the mode information is stored in step S309 and then the detailed setting screen 110 is displayed in step S311, but this is not limiting. When the OSD control unit 23 receives a selection input for the selection icon 101, it may obtain a group of initial setting values corresponding to the selected scene and output the group of initial setting values to the image control unit 25. The image control unit 25 corrects the image data using the obtained group of initial setting values. The image control unit 25 causes the projection unit 30 to project the projection image PG based on the corrected image data.

[0131] The image data includes device-specific information 53 that identifies the image providing device 50. The display method includes storing a screen display mode or a screen non-display mode in association with external device information 19 corresponding to the device-specific information 53, acquiring the device-specific information 53 included in the image data when the image data is input, and displaying a scene setting screen 100 when it is determined that the device-specific information 53 does not correspond to the external device information 19. When image data is input from an image providing device 50 that has never been connected to the projector 10, the scene setting screen 100 is displayed. The scene setting screen 100 is displayed to a user who is using the projector 10 for the first time. By checking the scene setting screen 100, the user can recognize that various settings are possible.

[0132] The display method includes displaying the scene setting screen 100 when it is determined that the device specific information 53 corresponds to the external device information 19 and the mode information associated with the external device information 19 is a screen display mode, and not displaying the scene setting screen 100 when it is determined that the mode information is a screen non-display mode. The scene setting screen 100 is displayed or hidden according to the stored mode information for the image providing device 50 that previously output image data to the projector 10. It is possible to set whether to display or hide the scene setting screen 100 for each image providing device 50.
