[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, in each drawing, the dimensions and scale of each part are appropriately different from those of the actual parts. Furthermore, since the embodiments described below are preferred specific examples of the present invention, various technically preferable limitations are applied, but the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is limited.

[0009] 1: First embodiment 1-1: Configuration of the first embodiment FIG. 1 is a block diagram showing an example of the configuration of a display device 10 according to a first embodiment. The display device 10 is, for example, a projection device such as a projector. The display device 10 includes an optical device 110, a processing device 130, a storage device 140, an operation device 150, and a communication device 160. The elements of the display device 10 are connected to each other by one or more buses for communicating information. Furthermore, the elements of the display device 10 are configured by one or more devices, and some elements of the display device 10 may be omitted.

[0010] The optical device 110 is a device that projects a projection image onto a projection surface such as a wall or a screen. The optical device 110 projects various projection images under the control of the processing device 130. The optical device 110 includes, for example, an illumination device, a liquid crystal panel, and a projection lens system, and modulates light from the illumination device using the liquid crystal panel. The optical device 110 also projects the modulated light onto the projection surface via the projection lens system. The optical device 110 is an example of a "display."

[0011] The processing device 130 is a processor that controls the entire display device 10, and is composed of, for example, one or more chips. The processing device 130 is composed of, for example, a central processing unit (CPU) that includes an interface with peripheral devices, an arithmetic unit, and registers. Note that some or all of the functions of the processing device 130 may be realized by hardware such as a digital signal processor (DSP), an application specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA). The processing device 130 executes various processes in parallel or sequentially.

[0012] The storage device 140 is a recording medium readable by the processing device 130, and stores a plurality of programs including the control program PR1 executed by the processing device 130. The storage device 140 may be configured by at least one of, for example, a read-only memory (ROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), and a random access memory (RAM). The storage device 140 may also be called a register, a cache, a main memory, a primary storage device, or the like.

[0013] The storage device 140 also stores a first parameter PM1 and a second parameter PM2. The first parameter PM1 is a parameter that is set by the user and stored in the storage device 140. The second parameter PM2 is not a parameter that is set by the user, but is a parameter that is stored in the storage device 140 in advance.

[0014] FIG. 2 is a table showing examples of first parameters PM1 and second parameters PM2. In the table shown in FIG. 2, the first parameter PM1 is included in the parameter set in the four columns on the left. The four parameter sets on the left, i.e., the "Brightness," "Contrast," "Saturation," "Tint," and "Sharpness" parameters included in the "Custom Settings" section for each of the four "Color Mode" modes, "Dynamics," "Vivid," "Cinema," and "Natural," are parameters set by the user. The first parameter PM1 represents these "Brightness," "Contrast," "Saturation," "Tint," and "Sharpness" parameters as examples. Note that, although there are five first parameters PM1 in this embodiment, there may be one, six, or more.

[0015] 2, the second parameter PM2 is included in the parameter set in the rightmost column, which is given the set name "Current Store Demo." In the parameter set called "Current Store Demo," the parameters "Brightness," "Contrast," "Saturation," "Tint," and "Sharpness" included in the "Custom Settings" section are not set by the user, but are parameters that are pre-stored in the storage device 140. Note that, although there are five second parameters PM2 in this embodiment, there may be one, or six or more.

[0016] Here, the "Current Store Demo" parameter set is, for example, a parameter set optimized to improve the appearance of the video of specific content. Specifically, this parameter set is a parameter set that improves the appearance of demo content when the display device 10 displays the video of the demo content in a store or exhibition hall where the display device 10 is exhibited. However, the parameter set of "Current Store Demo" is not limited to this, and may be any parameter set that is used when displaying video for a specific purpose, such as screen adjustment.

[0017] 1, the operation device 150 is a device used by a user of the display device 10 to operate the display device 10. The operation device 150 may be, for example, a panel-like device provided on the housing of the display device 10. Alternatively, the operation device 150 may be, for example, a remote controller that transmits and receives signals by wirelessly communicating with the display device 10. Operations performed by the user using the operation device 150 are input to the processing device 130.

[0018] The communication device 160 is hardware serving as a transmitting / receiving device for communicating with other devices. The communication device 160 is also called, for example, a network device, a network controller, a network card, or a communication module. The communication device 160 includes a connector for wired connection. The connector corresponds to an interface circuit. The communication device 160 may also include an interface for wireless communication. Examples of the interface for wireless communication include those compliant with wireless LAN and Bluetooth. Furthermore, "Bluetooth" is a registered trademark.

[0019] The processing device 130 reads and executes the control program PR1 from the storage device 140, thereby functioning as a reception unit 131, a determination unit 132, a first execution unit 133, a second execution unit 134, and a communication control unit 135. Note that the control program PR1 may be transmitted from another device, such as a server that manages the display device 10, via a communication network.

[0020] The reception unit 131 receives a first operation or a second operation from the user via the operation device 150. The first operation corresponds to the first parameter PM1 described above. The second operation corresponds to the second parameter PM2 described above. The first operation and the second operation are different from each other.

[0021] The determination unit 132 determines whether or not the receiving unit 131 has received a first operation. The determination unit 132 also determines whether or not the receiving unit 131 has received a second operation.

[0022] The first execution unit 133 executes a first mode in which an image is displayed in a manner based on at least the first parameter PM1, when triggered by a first operation being performed on the operation device 150. Specifically, the first execution unit 133 causes the optical device 110 to project a projection image onto the projection surface in a manner based on at least the first parameter PM1, when triggered by the first operation being performed on the operation device 150. As a result, the first execution unit 133 displays the projection image on the projection surface.

[0023] The second execution unit 134 executes a second mode in which an image is displayed in a manner based on at least the second parameter PM2, when triggered by a second operation being performed on the operation device 150. Specifically, the second execution unit 134 causes the optical device 110 to project a projection image onto the projection surface in a manner based on at least the second parameter PM2, when triggered by a second operation being performed on the operation device 150. As a result, the second execution unit 134 displays the projection image on the projection surface.

[0024] Here, it is preferable that the second execution unit 134 causes the optical device 110 to project a projection image based on image data different from image data supplied to the display device 10 from a device external to the display device 10. The image data supplied to the display device 10 from the external device is an example of "supplied data." Moreover, the image data different from the "supplied data" is an example of "first data."

[0025] Furthermore, the second execution unit 134 preferably causes the optical device 110 to project onto the projection surface a projection image indicating that the second mode is being executed, superimposed on the projection image based on the first data. The projection image indicating that the second mode is being executed is an example of an "instruction image DP."

[0026] Fig. 3 is a diagram showing an example of a instruction image DP. The instruction image DP shown in Fig. 3 is a horizontally long rectangle and includes the word "DEMO" in the upper right corner. The display mode of the instruction image DP is preferably optimized to match the gradation and color tone of the projection image based on the first data.

[0027] As described above, when the receiving unit 131 receives a first operation, the first execution unit 133 executes a first mode in which an image is displayed in a manner based on at least the first parameter PM1. On the other hand, when the receiving unit 131 receives a second operation, the second execution unit 134 executes a second mode in which an image is displayed in a manner based on at least the second parameter PM2.

[0028] Here, the second operation is, for example, pressing and holding a specific key on the operation device 150 or pressing a combination of multiple specific keys.

[0029] Furthermore, the transition from the first mode to the second mode may be possible when the display device 10 displays all types of video, or may be possible only when it displays some types of video. The "some types of video" may be, for example, video of demo content in a store or exhibition hall. Note that, depending on the selection of video that allows the transition from the first mode to the second mode, some parameters included in the parameter set exemplified in FIG. 2 may not be available.

[0030] Furthermore, if the receiving unit 131 receives a first operation while the second mode is being executed, the second mode is canceled and the first mode is executed. Here, the first operation, like the second operation, is, for example, a long press of a specific key on the operation device 150 or a combination of pressing specific keys. The long press of a specific key or a combination of pressing specific keys may be, for example, pressing a key to display an OSD (On Screen Display). These keys preferably do not include frequently used keys, such as a power button or a volume button. Furthermore, when the second mode is canceled, it is preferable that a message indicating that the second mode has been canceled is displayed on the OSD. Furthermore, after the second mode is canceled, the instruction image DP is erased.

[0031] In addition, when the display device 10 is turned off in the second mode and then turned on again, it is preferable that the display device 10 starts up in the second mode. In this case, it is preferable that the instruction image DP is displayed when the display device 10 starts up.

[0032] Furthermore, when a user sets parameters for some items corresponding to the first mode, parameters for other items may become hidden depending on the setting item. In this case, if the user transitions to the second mode while leaving the parameters for the other items hidden, if the parameters for the "other items" corresponding to the second mode remain hidden, after transitioning to the second mode, the parameters for the "other items" will become unconfigurable, even though they should be configurable.

[0033] Therefore, when transitioning to the second mode, it is preferable that the settings of the second mode be given priority, specifically that the parameters of hidden items be returned to their initial values.

[0034] As an example, the display condition for the item "HDR10 Settings" is that the item "Dynamic Range" is set to "Auto" and the item "Video Signal" is set to "HDR10," or a first condition that the item "Dynamic Range" is set to "HDR10" and a second condition that the item "Dynamic Tone Mapping" is set to "Off" are both satisfied. Here, if the item "Dynamic Tone Mapping" is set to "On" when the first mode is being executed, the item "HDR10 Settings" will not be displayed when the second mode is being executed. For this reason, it is preferable to set the item "Dynamic Tone Mapping" to "Off" when transitioning from the first mode to the second mode.

[0035] In FIG. 1, a communication control unit 135 causes a communication device 160 to transmit and receive various data to and from devices external to the display device 10.

[0036] 1-2: Operation of the first embodiment FIG. 4 is a flowchart showing the operation of the display device 10 according to the first embodiment.

[0037] In step S1, the processing device 130 functions as the determination unit 132. When the processing device 130 has accepted the first operation as the acceptance unit 131, the processing device 130 executes the process of step S2. When the processing device 130 has not accepted the first operation as the acceptance unit 131, the processing device 130 executes the process of step S3.

[0038] In step S2, the processing device 130 functions as a first execution unit 133. The processing device 130 executes a first mode in which a projection image is displayed on the projection surface by causing the optical device 110 to project the projection image onto the projection surface in a manner based on the first parameter PM1.

[0039] In step S3, the processing device 130 functions as the determination unit 132. If the processing device 130 has accepted the second operation as the acceptance unit 131, the processing device 130 executes the process of step S4. If the processing device 130 has not accepted the second operation as the acceptance unit 131, the processing device 130 executes the process of step S1.

[0040] In step S4, the processing device 130 functions as the second execution unit 134. The processing device 130 executes a second mode in which the projection image is displayed on the projection surface by causing the optical device 110 to project the projection image onto the projection surface in a manner based on the second parameter PM2.
