Detailed Implementation

[0025] Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0026] In addition, in the following figures, the scale of the dimensions is sometimes different depending on the structural element to facilitate observation of the structural elements.

[0027] [First Implementation]

[0028] First, the first embodiment of this disclosure will be described.

[0029] Figure 1 This is a block diagram schematically illustrating the structure of the image display system 1 of this embodiment. For example... Figure 1As shown, the image display system 1 of this embodiment includes a first image display device 10 and a second image display device 20. The first image display device 10 is, for example, an information processing device with image display capabilities such as a desktop PC, a notebook PC, a tablet terminal, and a smartphone. More specifically, the first image display device 10 is a device capable of launching a specified application and displaying the GUI (Graphical User Interface) provided by the application. As an example, the first image display device 10 in this embodiment is a notebook PC.

[0030] The second image display device 20 is an image display device different from the first image display device 10. As an example, in this embodiment, the second image display device 20 is a projector that displays an image on a projection surface 100 by projecting image light L onto the projection surface 100. The projection surface 100 can be a dedicated projector screen, or it can be a wall, etc. In the following description, the projection of image light L by the second image display device 20 is sometimes referred to as "the second image display device 20 displays an image".

[0031] The first image display device 10 and the second image display device 20 are connected via a communication cable (not shown). The first image display device 10 supplies an image signal to the second image display device 20 via the communication cable. The second image display device 20 generates an image light L based on the image signal supplied from the first image display device 10 and projects the generated image light L onto the projection surface 100.

[0032] The first image display device 10 includes a first input device 11, a first display device 12, a first communication unit 13, a first memory 14, and a first processor 15. The second image display device 20 includes a second input device 21, a second display device 22, a second communication unit 23, a speaker 24, a second memory 25, and a second processor 26.

[0033] The first input device 11 is a device that accepts input operations from the user on the first image display device 10. As an example, the first input device 11 includes a keyboard 11a and a mouse 11b. The first input device 11 outputs the electrical signals generated by the user's operation of the keyboard 11a and mouse 11b as a first operation signal to the first processor 15.

[0034] The first display device 12 is a display panel that displays a specified image under the control of the first processor 15. For example, the first display device 12 is a liquid crystal display or a thin display such as an organic EL (Electro-Luminescence) display, which is mounted on the first image display device 10 as a notebook PC.

[0035] The first communication unit 13 is a communication interface connected to the second communication unit 23 of the second image display device 20 via a communication cable, and for example, has an interface circuit. The first communication unit 13 outputs signals received from the second communication unit 23 to the first processor 15. In addition, the first communication unit 13 sends various signals, such as image signals, input from the first processor 15 to the second communication unit 23. The first communication unit 13 also has the following functions: accessing the Internet via a wireless LAN (Local Area Network) that supports wireless communication standards such as Wi-Fi (registered trademark), and communicating with an Internet server (not shown) that provides various services such as image distribution services.

[0036] The first memory 14 includes: non-volatile memory storing programs and various setting data required for the first processor 15 to perform various processes; and volatile memory serving as a temporary storage destination for data during the execution of various processes by the first processor 15. For example, the non-volatile memory is EEPROM (Electrically Erasable Programmable Read-Only Memory) or flash memory. The volatile memory is, for example, RAM (Random Access Memory). The programs stored in the first memory 14 also include software for image adjustment applications, which will be described later.

[0037] The first processor 15 is an arithmetic processing device that controls the overall operation of the first image display device 10 according to a program pre-stored in the first memory 14. For example, the first processor 15 may consist of one or more CPUs (Central Processing Units). Part or all of the functionality of the first processor 15 may also be constructed using circuits such as DSPs (Digital Signal Processors), ASICs (Application Specific Integrated Circuits), PLDs (Programmable Logic Devices), and FPGAs (Field Programmable Gate Arrays). The first processor 15 executes various processes in parallel or sequentially.

[0038] For example, the first processor 15 performs a predetermined process based on a first operation signal input from the first input device 11 and a signal received from the second image display device 20 via the first communication unit 13, thereby displaying an image representing the processing result on the first display device 12. Furthermore, the first processor 15 transmits various signals, including the processing result signal and image signals, to the second image display device 20 via the first communication unit 13.

[0039] The second input device 21 is a device that accepts user input operations on the second image display device 20. As an example, the second input device 21 includes an operation unit 21a and a light-receiving unit 21b. The operation unit 21a consists of a plurality of operation keys provided on the second image display device 20. For example, the operation keys include a power key, a menu key, directional keys, a confirmation key, and a volume adjustment key. The operation keys can be hardware keys or software keys displayed on the touch panel of the second image display device 20. The operation unit 21a outputs the electrical signals generated by the user operating each operation key as second operation signals to the second processor 26.

[0040] The light-receiving unit 21b includes a photoelectric conversion circuit that receives infrared light transmitted from the remote control (not shown) of the second image display device 20 and converts it into an electrical signal. The light-receiving unit 21b outputs the electrical signal obtained through the photoelectric conversion of infrared light to the second processor 26 as a remote operation signal. The remote control, like the operation unit 21a, has multiple operation keys. The remote control converts the electrical signals generated by the user operating each of the operation keys into infrared light and sends it to the second image display device 20. That is, the remote operation signal output from the light-receiving unit 21b is substantially the same as the electrical signals generated by the user operating each of the operation keys of the remote control. Furthermore, when the remote control transmits radio wave signals according to a short-range wireless communication standard such as Bluetooth (registered trademark), a receiving device for receiving radio wave signals can be provided instead of the light-receiving unit 21b.

[0041] The second display device 22, controlled by the second processor 26, generates image light L representing a color image and projects the generated image light L onto the projection surface 100. The second display device 22 can also be referred to as a projection device. The second display device 22 has a first image generation panel 22a, a second image generation panel 22b, a third image generation panel 22c, a dichroic prism 22d, and a projection optical system 22e.

[0042] The first image generation panel 22a generates red image light LR representing a red image and emits it into the dichroic prism 22d. The first image generation panel 22a has multiple pixels arranged in a matrix, each of which emits red light. The red image light LR is emitted from the first image generation panel 22a by the second processor 26 controlling the amount of red light emitted from each pixel.

[0043] The second image generation panel 22b generates green image light LG representing a green image and emits it into the dichroic prism 22d. The second image generation panel 22b has multiple pixels configured in a matrix, each of which emits green light. The green image light LG is emitted from the second image generation panel 22b by the second processor 26 controlling the amount of green light emitted from each pixel.

[0044] The third image generation panel 22c generates a blue image light LB representing a blue image and emits it into the dichroic prism 22d. The third image generation panel 22c has multiple pixels configured in a matrix, each of which emits blue light. The blue image light LB is emitted from the third image generation panel 22c by the second processor 26 controlling the amount of blue light emitted by each pixel.

[0045] For example, each image generating panel 22a, 22b, and 22c can be a self-emissive electro-optical device such as an OLED (Organic Light Emitting Diode) panel or a μLED (Micro Light Emitting Diode) panel. Alternatively, each image generating panel 22a, 22b, and 22c can also be a liquid crystal panel or a non-self-emissive electro-optical device such as a DMD (Digital Micromirror Device). When each image generating panel 22a, 22b, and 22c is a non-self-emissive electro-optical device, light from a light source (not shown) such as an LED is separated into red light, green light, and blue light, respectively. Red light is incident on the first image generating panel 22a. Green light is incident on the second image generating panel 22b. Blue light is incident on the third image generating panel 22c. Alternatively, a single-panel image generating panel can be used to emit light of each color in a time-division multiplexing manner.

[0046] The dichroic prism 22d synthesizes the red image light LR, the green image light LG, and the blue image light LB to generate an image light L representing a color image, which is then emitted into the projection optical system 22e. The projection optical system 22e, composed of multiple optical elements such as lenses, magnifies and projects the image light L emitted from the dichroic prism 22d toward the projection surface 100. Although not illustrated, the projection optical system 22e includes mechanisms for adjusting optical parameters such as lens shift, lens focus, and lens zoom. These mechanisms are controlled by the second processor 26 to adjust the optical parameters of the projection optical system 22e.

[0047] The second communication unit 23 is a communication interface connected to the first communication unit 13 of the first image display device 10 via a communication cable, and for example, has an interface circuit. The second communication unit 23 outputs various signals, such as image signals, received from the first communication unit 13 to the second processor 26. In addition, the second communication unit 23 sends signals input from the second processor 26 to the first communication unit 13.

[0048] The speaker 24, controlled by the second processor 26, outputs sound at a predetermined volume. The second memory 25 includes: non-volatile memory storing programs and various setting data required for the second processor 26 to perform various processes; and volatile memory serving as a temporary storage destination for data when the second processor 26 performs various processes.

[0049] The second processor 26 is an arithmetic processing device that controls the overall operation of the second image display device 20 according to a program pre-stored in the second memory 25. For example, the second processor 26 may consist of one or more CPUs. Some or all of the functions of the second processor 26 may also be implemented using circuits such as DSPs, ASICs, PLDs, and FPGAs. The second processor 26 executes various processes in parallel or sequentially.

[0050] For example, the second processor 26 controls the second display device 22 and the speaker 24 based on the second operation signal input from the operation unit 21a, the remote operation signal input from the light receiving unit 21b, and the signal received from the first image display device 10 via the second communication unit 23. Specifically, the second processor 26 controls the second display device 22 to display (project) an image based on the image data contained in the image signal supplied from the first image display device 10 onto the projection surface 100, and controls the speaker 24 to output sound based on the sound data contained in the image signal.

[0051] Next, the operation of the image display system 1 configured as described above will be explained.

[0052] Figures 2 to 5This is a flowchart illustrating the image adjustment process performed by the first processor 15 of the first image display device 10. When the first processor 15 receives an operation to initiate an image adjustment application, it reads and executes the software for the image adjustment application from the first memory 14, thereby executing... Figures 2 to 5 The image adjustment process shown.

[0053] Launching an image adjustment application, for example, means that the user uses mouse 11b to double-click the launch icon of the image adjustment application displayed on the screen of the first display device 12.

[0054] like Figure 2 As shown, when the first processor 15 starts the image adjustment process, it first displays the application window containing the image 200 with the adjustment method selection as a GUI on the first display device 12 (step S1).

[0055] Figure 6 This is an example of an image 200 representing an adjustment method selection image. The adjustment method selection image 200 is an image that requests the user to select a tone adjustment method for the input image. The adjustment method selection image 200 includes a first option image 210 representing the first option and a second option image 220 representing the second option. The adjustment method selection image 200 corresponds to "selecting an image".

[0056] The first option image 210 contains a string corresponding to the first option. For example, the string corresponding to the first option is "adjust it yourself". As described later, when the first processor 15 receives an operation to select the first option image 210, it performs processing to adjust the tone of the input image according to the operation received by the user. The first option image 210 corresponds to "the sixth image".

[0057] The second option image 220 contains a string corresponding to the second option. For example, the string corresponding to the second option is "Read professional data". As described later, when the first processor 15 receives an operation to select the second option image 220, it accesses the Internet via the first communication unit 13 and performs processing to receive tone setting values ​​from an Internet server for tone adjustment of the input image. The second option image 220 corresponds to "the seventh image".

[0058] The application window displayed on the screen of the first display device 12 includes not only the adjustment method selection image 200 as described above, but also various operation icons for image adjustment, icons for changing the size of the application window, and icons for closing the application window. The various icons included in the application window correspond to "Image 8". The application window corresponds to "Image 5".

[0059] An input image is an image represented by image data contained in an image signal. The image signal can be an image signal received from an Internet server providing image distribution services, or it can be an image signal from a DVD read by a DVD (Digital Versatile Disc) drive (not shown) mounted on the first image display device 10. An input image is an original image that is input to the first image display device 10 via the Internet or a DVD drive, as described above, and that has not undergone image processing such as tone adjustment or shape correction after being input to the first image display device 10.

[0060] like Figure 2 As shown, during the display of the adjustment method selection image 200, the first processor 15 determines whether the operation of selecting the first option image 210 has been accepted based on the first operation signal input from the first input device 11 (step S2). In other words, the first processor 15 determines whether the operation of selecting the first option, namely "adjust manually", as the tone adjustment method has been accepted.

[0061] When the first processor 15 determines that it has accepted the operation of selecting the first option image 210 (step S2: Yes), it causes the first display device 12 to display an application window containing the first image type selection image 300 (step S3). The operation of selecting the first option image 210 means, for example, that the user clicks the first option image 210 with the mouse 11b.

[0062] On the other hand, if the first processor 15 determines that no operation to select the first option image 210 was performed during the period of selecting image 200 in the display adjustment method (step S2: No), it transfers to Figure 5 The flowchart shows step S25. That is, when the first processor 15 determines that it has accepted the operation of selecting the second option image 220, it proceeds to step S25.

[0063] In other words, if the first processor 15 determines that it has accepted the operation of selecting the second option, namely "import professional data" as the tone adjustment method, it proceeds to step S25. The operation of selecting the second option image 220 means, for example, that the user clicks the second option image 220 with the mouse 11b. Hereinafter, the processing performed when the first processor 15 accepts the operation of selecting the first option image 210 will be explained.

[0064] Figure 7This diagram illustrates an example of a first image type selection image 300. The first image type selection image 300 is an image that requests the user to select the image type of the input image. The first image type selection image 300 includes a first candidate image 310, a second candidate image 320, a third candidate image 330, a fourth candidate image 340, a selection box 350, a forward operation button 360, a back operation button 370, and a detailed settings button 380. The first image type selection image 300 corresponds to "first setting image".

[0065] The first candidate image 310 is an image representing a first tone setting value corresponding to the first image type. For example, the first image type is "moving". The first tone setting value is pre-stored in the first memory 14. The first candidate image 310 includes a preview image of an input image with its tone adjusted based on the first tone setting value, and the string "moving" corresponding to the first tone setting value. The first tone setting value corresponds to "first setting value". The first candidate image 310 corresponds to "first image".

[0066] The second candidate image 320 is an image representing a second tone setting value corresponding to the second image type. For example, the second image type is "Cinema". The second tone setting value is pre-stored in the first memory 14. The second candidate image 320 includes a preview image of an input image with its tone adjusted based on the second tone setting value, and the string "Cinema" corresponding to the second tone setting value. The second tone setting value corresponds to "Second Setting Value". The second candidate image 320 corresponds to "Second Image".

[0067] The third candidate image 330 is an image representing a third tone setting value corresponding to the third image type. As an example, the third image type is "TV series". The third tone setting value is pre-stored in the first memory 14. The third candidate image 330 includes a preview image of an input image with the tone adjusted based on the third tone setting value, and the string "TV series" corresponding to the third tone setting value.

[0068] The fourth candidate image 340 is an image representing a fourth tone setting value corresponding to the fourth image type. As an example, the fourth image type is "game". The fourth tone setting value is pre-stored in the first memory 14. The fourth candidate image 340 includes a preview image of the input image with the tone adjusted based on the fourth tone setting value, and the string "game" corresponding to the fourth tone setting value.

[0069] In addition, Figure 7In the first candidate image 310 to the fourth candidate image 340, the first candidate image 310 to the fourth candidate image 340 are represented as black and white images with the same hue, but in the actual first image type selection image 300, the first candidate image 310 to the fourth candidate image 340 are color images with different hues depending on the image type.

[0070] Selection box 350 is a rectangular frame-shaped image used to select one of the first candidate images 310 to the fourth candidate images 340. The first processor 15 identifies the candidate image surrounded by selection box 350 among the first candidate images 310 to the fourth candidate images 340 as the candidate image (image type) selected by the user.

[0071] The forward operation button 360 is used to instruct the first processor 15 to switch the image displayed in the application window from the first image type selection image 300 to the next brightness selection image 400. As an example, the forward operation button 360 contains the string "Next Page".

[0072] The return operation button 370 is used to instruct the first processor 15 to return from the first image type selection image 300 to the immediately preceding adjustment method selection image 200 (icon) displayed in the application window. As an example, the return operation button 370 contains the string "Return".

[0073] The detailed settings button 380 is an image (icon) used to instruct the first processor 15 to switch the image displayed in the application window from image type selection image 300 to detailed settings image 700. As an example, the detailed settings button 380 contains the string "Jump to detailed settings".

[0074] like Figure 2 As shown, during the display of the first image type selection image 300, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether the first operation of selecting the second candidate image 320 has been accepted (step S4). In other words, the first processor 15 determines whether the first operation of selecting "cinema" as the second image type has been accepted. The first operation of selecting the second candidate image 320 means, for example, that after the user places the selection box 350 at the position of the second candidate image 320 using the mouse 11b, they click the forward operation button 360.

[0075] If the first processor 15 determines that it has accepted the first operation of selecting the second candidate image 320 (i.e., "cinema") (step S4: Yes), it skips the processing of steps S5 to S9 described below and proceeds to the next step. Figure 3 Step S10 in the flowchart. Regarding... Figure 3 The processing after step S10 in the flowchart will be explained later.

[0076] On the other hand, if the first processor 15 determines that the first operation of selecting the second candidate image 320 has not been accepted (step S4: No), it determines whether the first operation of selecting a candidate image other than the second candidate image 320 from the first candidate image 310 to the fourth candidate image 340 has been accepted (step S5). In other words, the first processor 15 determines whether the first operation of selecting an image type other than "cinema" has been accepted.

[0077] If the first processor 15 determines that the first operation of selecting a candidate image other than the second candidate image 320 has not been accepted (step S5: No), it determines whether the operation of pressing the detailed settings button 380 has been accepted (step S6).

[0078] If the first processor 15 determines that the operation of pressing the detailed setting button 380 has been accepted (step S6: Yes), it proceeds to... Figure 4 Step S18 in the flowchart. Pressing the detailed settings button 380, for example, means the user clicks the detailed settings button 380 using mouse 11b. About Figure 4 The processing after step S18 in the flowchart will be explained later.

[0079] If the first processor 15 determines that the operation of pressing the detailed settings button 380 has not been accepted (step S6: No), it returns to step S4. Additionally, although in Figure 2 Not illustrated, but if the first processor 15 determines that an operation to press the return operation button 370 was performed while the first image type selection image 300 was being displayed, it returns to step S1 and returns the image displayed in the application window from the first image type selection image 300 to the immediately preceding adjustment method selection image 200. The operation to press the return operation button 370 is, for example, when the user clicks the return operation button 370 using the mouse 11b.

[0080] If the first processor 15 determines that it has accepted the first operation of selecting a candidate image other than the second candidate image 320 (step S5: Yes), it causes the first display device 12 to display an application window containing the brightness selection image 400 (step S7). For example, if the first processor 15 determines that it has accepted the first operation of selecting the first candidate image 310 (i.e., "dynamic"), it causes the first display device 12 to display an application window containing the brightness selection image 400.

[0081] Figure 8This is an example of a brightness selection image 400. The brightness selection image 400 is an image that prompts the user to select the brightness of an input image. The brightness selection image 400 includes a fifth candidate image 410, a sixth candidate image 420, a selection box 430, a forward operation button 440, a back operation button 450, and a detailed settings button 460. The brightness selection image 400 corresponds to the "second setting image".

[0082] The fifth candidate image 410 is an image representing the fifth hue setting value corresponding to the word "bright" as a term representing luminance. The fifth hue setting value is pre-stored in the first memory 14. The fifth candidate image 410 includes a preview image of an input image with its hue adjusted based on the fifth hue setting value, and the string "bright" corresponding to the fifth hue setting value. The fifth hue setting value corresponds to the "third setting value". The fifth candidate image 410 corresponds to the "third image".

[0083] The sixth candidate image 420 is an image representing a sixth hue setting value corresponding to the word "dark" as a term representing brightness. The sixth hue setting value is pre-stored in the first memory 14. The sixth candidate image 420 includes a preview image of an input image with its hue adjusted based on the sixth hue setting value, and the string "dark" corresponding to the sixth hue setting value. The sixth hue setting value corresponds to "the fourth setting value." The sixth candidate image 420 corresponds to "the fourth image."

[0084] In addition, Figure 8 In the image, the fifth candidate image 410 and the sixth candidate image 420 are represented as black and white images, but in the actual brightness selection image 400, the fifth candidate image 410 and the sixth candidate image 420 are color images with different brightness.

[0085] Selection box 430 is a rectangular frame-shaped image used to select one of the fifth candidate image 410 and the sixth candidate image 420. The first processor 15 identifies the candidate image surrounded by selection box 430 in the fifth candidate image 410 and the sixth candidate image 420 as the candidate image (brightness) selected by the user.

[0086] The forward operation button 440 is used to instruct the first processor 15 to switch the image displayed in the application window from the brightness selection image 400 to the next adjustment color selection image 500. As an example, the forward operation button 440 contains the string "Next Page".

[0087] The return operation button 450 is used to instruct the first processor 15 to return the image (icon) displayed in the application window from the brightness selection image 400 to the immediately preceding first image type selection image 300. As an example, the return operation button 450 contains the string "Return".

[0088] The detailed settings button 460 is an image (icon) used to instruct the first processor 15 to switch the image displayed in the application window from the brightness selection image 400 to the detailed settings image 700. For example, the detailed settings button 460 contains the string "Jump to detailed settings". The detailed settings button 460 corresponds to "Image 5".

[0089] like Figure 2 As shown, during the display of the brightness selection image 400, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether a second operation (step S8) has been accepted to select one of the fifth candidate image 410 and the sixth candidate image 420. In other words, the first processor 15 determines whether a second operation has been accepted to select one of "bright" and "dark" as the brightness of the input image.

[0090] The second operation of selecting one of the 5th candidate image 410 and the 6th candidate image 420 means, for example, that after the user uses the mouse 11b to place the selection box 430 at the position of one of the 5th candidate image 410 and the 6th candidate image 420, he clicks the forward operation button 440.

[0091] If the first processor 15 determines that the second operation of selecting one of the fifth candidate image 410 and the sixth candidate image 420 has not been accepted (step S8: No), it determines whether the third operation of pressing the detailed settings button 460 has been accepted (step S9). If the first processor 15 determines that the third operation of pressing the detailed settings button 460 has been accepted (step S9: Yes), it proceeds to... Figure 4 Step S18 in the flowchart. Regarding... Figure 4 The processing after step S18 in the flowchart will be explained later.

[0092] If the first processor 15 determines that the third operation of pressing the detailed settings button 460 has not been accepted (step S9: No), it returns to step S8. Additionally, although in Figure 2 Not shown in the figure, but if the first processor 15 determines that the operation of pressing the return operation button 450 was performed during the display of the brightness selection image 400, it returns to step S3 and returns the image displayed in the application window from the brightness selection image 400 to the immediately preceding first image type selection image 300.

[0093] If the first processor 15 determines that the second operation of selecting one of the fifth candidate image 410 and the sixth candidate image 420 has been accepted (step S8: Yes), it proceeds to... Figure 3 Step S10 in the flowchart.

[0094] like Figure 3 As shown, when transitioning to step S10, the first processor 15 causes the first display device 12 to display an application window containing the color selection image 500 (step S10).

[0095] Figure 9 This diagram illustrates an example of an image selection tool 500 for adjusting color selection. Image selection tool 500 prompts the user to select the desired hue from three tones: red, blue, and green from an input image. Image selection tool 500 includes a 7th candidate image 510, an 8th candidate image 520, a 9th candidate image 530, a selection box 540, a forward button 550, a back button 560, and a detailed settings button 570. Image selection tool 500 corresponds to "4th setting image".

[0096] The seventh candidate image 510 is an image representing a seventh hue setting value used to emphasize the red tones of the input image. The seventh hue setting value is pre-stored in the first memory 14. The seventh candidate image 510 includes a preview image of the input image with the red tones adjusted based on the seventh hue setting value, and the string "enhanced red tones" corresponding to the seventh hue setting value.

[0097] The 8th candidate image 520 is an image representing an 8th tone setting value used to emphasize the blue tones of the input image. The 8th tone setting value is pre-stored in the first memory 14. The 8th candidate image 520 includes a preview image of the input image with the blue tones adjusted based on the 8th tone setting value, and the string "enhanced blue tones" corresponding to the 8th tone setting value.

[0098] The 9th candidate image 530 is an image representing a 9th hue setting value used to emphasize the green tones of the input image. The 9th hue setting value is pre-stored in the 1st memory 14. The 9th candidate image 530 includes a preview image of the input image with the green tones adjusted based on the 9th hue setting value, and the string "enhanced green tones" corresponding to the 9th hue setting value.

[0099] In addition, Figure 9 In the original text, candidate images 510 to 530 are represented as black and white images, but in the actual color selection image 500, candidate images 510 to 530 are color images that emphasize different hues.

[0100] Selection box 540 is a rectangular frame-shaped image used to select one of the 7th candidate image 510 to the 9th candidate image 530. The first processor 15 identifies the candidate image surrounded by selection box 540 among the 7th candidate image 510 to the 9th candidate image 530 as the candidate image selected by the user (the tone to be emphasized).

[0101] The forward operation button 550 is an image (icon) used to instruct the first processor 15 to switch the image displayed in the application window from the color adjustment selection image 500 to the next final confirmation image 600. As an example, the forward operation button 550 contains the string "Next Page".

[0102] The return operation button 560 is used to instruct the first processor 15 to return the image (icon) displayed in the application window from the color adjustment selection image 500 to the immediately preceding brightness selection image 400. As an example, the return operation button 560 contains the string "Return".

[0103] The detailed settings button 570 is an image (icon) used to instruct the first processor 15 to switch the image displayed in the application window from the color adjustment selection image 500 to the detailed settings image 700. As an example, the detailed settings button 570 contains the string "Jump to detailed settings".

[0104] like Figure 3 As shown, during the display of the color selection image 500, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether to accept the fifth operation (step S11) of selecting one of the seventh candidate images 510 to the ninth candidate images 530. In other words, the first processor 15 determines whether to accept the fifth operation of selecting the hue to be emphasized from the three hues of red, blue, and green in the input image.

[0105] The fifth operation, which selects one of the 7th candidate image 510 to the 9th candidate image 530, means, for example, that after the user uses the mouse 11b to place the selection box 540 at one of the 7th candidate image 510 to the 9th candidate image 530, they click the forward operation button 550.

[0106] If the first processor 15 determines that the fifth operation of selecting one of the seventh candidate images 510 to the ninth candidate images 530 has not been accepted (step S11: No), it determines whether the operation of pressing the detailed settings button 570 has been accepted (step S12). If the first processor 15 determines that the operation of pressing the detailed settings button 570 has been accepted (step S12: Yes), it proceeds to... Figure 4 Step S18 in the flowchart. Regarding... Figure 4The processing after step S18 in the flowchart will be explained later.

[0107] If the first processor 15 determines that the operation of pressing the detailed settings button 570 has not been accepted (step S12: No), it returns to step S11. Additionally, although in Figure 3 Not shown in the figure, but if the first processor 15 determines that the operation of pressing the return operation button 560 was performed during the display of the adjustment color selection image 500, it returns to step S7 and returns the image displayed in the application window from the adjustment color selection image 500 to the immediately preceding brightness selection image 400.

[0108] If the first processor 15 determines that it has accepted the fifth operation of selecting one of the seventh candidate images 510 to the ninth candidate images 530 (step S11: yes), it causes the first display device 12 to display an application window containing the final confirmation image 600 (step S13).

[0109] Figure 10 This is an example of a final confirmation image 600. The final confirmation image 600 is an image that allows the user to confirm the tones of an input image adjusted based on the user's actions. The final confirmation image 600 includes a final preview image 610, an OK button 620, and a detailed settings button 630.

[0110] The final preview image 610 is a preview image of the input image whose hue has been adjusted based on the user's operation. For example, if step S13 is performed after step S11, the final preview image 610 is a preview image of the input image whose hue has been adjusted based on the first operation, the second operation, and the fifth operation.

[0111] In addition, Figure 10 In the process, the final preview image 610 is represented as a black and white image, but in the actual final confirmation image 600, the final preview image 610 is a color image of the input image whose hue has been adjusted based on the first operation, the second operation, and the fifth operation.

[0112] As already explained, the first operation refers to selecting one of the first candidate images 310 to the fourth candidate image 340 during the display of the first image type selection image 300. The second operation refers to selecting one of the fifth candidate image 410 and the sixth candidate image 420 during the display of the brightness selection image 400. The fifth operation refers to selecting one of the seventh candidate image 510 to the ninth candidate image 530 during the display of the color adjustment selection image 500.

[0113] The OK button 620 is an image (icon) used to notify the first processor 15 that the final preview image 610 has been confirmed. For example, the OK button 620 contains the string "OK". The OK button 620 can also be referred to as the confirmation button.

[0114] The detailed settings button 630 is an image (icon) used to instruct the first processor 15 to switch the image displayed in the application window from the final confirmation image 600 to the detailed settings image 700. As an example, the detailed settings button 630 contains the string "Jump to detailed settings".

[0115] like Figure 3 As shown, during the display of the final confirmation image 600, the first processor 15 determines whether the operation of pressing the OK button 620 has been accepted based on the first operation signal input from the first input device 11 (step S14). If the first processor 15 determines that the operation of pressing the OK button 620 has not been accepted (step S14: No), it determines whether the operation of pressing the detailed settings button 630 has been accepted (step S15).

[0116] If the first processor 15 determines that the operation of pressing the detailed setting button 630 has been accepted (step S15: Yes), it proceeds to... Figure 4 Step S18 in the flowchart. Regarding... Figure 4 The processing after step S18 in the flowchart will be explained later. If the first processor 15 determines that the operation of pressing the detailed setting button 630 has not been accepted (step S15: No), it returns to step S14.

[0117] If the first processor 15 determines that the operation of pressing the OK button 620 has been accepted (step S14: Yes), it adjusts the tone of the input image based on the operation accepted by the user (step S16). For example, if step S13 is executed after step S11, the first processor 15 adjusts the tone of the input image according to the first operation, the second operation, and the fifth operation.

[0118] Specifically, for example, in a first scenario where a first candidate image 310 is selected through the first operation, a fifth candidate image 410 is selected through the second operation, and a seventh candidate image 510 is selected through the fifth operation, the first processor 15 reads the first tone setting value, the fifth tone setting value, and the seventh tone setting value from the first memory 14. This first scenario can be described as a scenario where "dynamic" is selected as the image type of the input image through the first operation, "brightness" is selected as the brightness of the input image through the second operation, and "red tone" is selected as the tone to be emphasized through the fifth operation.

[0119] In this first scenario, the first processor 15 rewrites the image data representing the input image based on the first tone setting value, the fifth tone setting value, and the seventh tone setting value, thereby adjusting the tone of the input image.

[0120] For example, in a second scenario where a second candidate image 320 is selected through the first operation and a seventh candidate image 510 is selected through the fifth operation, the first processor 15 reads the second tone setting value and the seventh tone setting value from the first memory 14. This second scenario can be described as a scenario where "cinema" is selected as the image type of the input image through the first operation, and "red tone" is selected as the tone to be emphasized through the fifth operation.

[0121] In the second scenario, since "cinema" is selected as the image type for the input image through the first operation, the processing from steps S5 to S9 is skipped. That is, in the second scenario, the processing of displaying the brightness selection image 400 and accepting the second operation is skipped. In this second scenario, the first processor 15 rewrites the image data representing the input image based on the second tone setting value and the seventh tone setting value, thereby adjusting the tone of the input image.

[0122] After adjusting the tone of the input image as described above, the first processor 15 sends the tone-adjusted input image to the second image display device 20 via the first communication unit 13 (step S17). Specifically, in step S17, the first processor 15 sends an image signal containing image data rewritten based on the tone setting value read from the first memory 14 to the second image display device 20 via the first communication unit 13.

[0123] When the second processor 26 of the second image display device 20 receives an image signal from the first image display device 10 via the second communication unit 23, it controls the second display device 22 to project an image light L representing an input image with adjusted hue, based on the image data contained in the image signal. As a result, the input image with adjusted hue according to the user's operation is displayed on the projection surface 100.

[0124] The following is about Figure 4 The processing after step S18 in the flowchart will be explained. For example... Figure 4 As shown, when the process moves to step S18, the first processor 15 causes the first display device 12 to display an application window containing a detailed settings image 700 (step S18).

[0125] Figure 11This diagram illustrates an example of a detailed setting image 700. The detailed setting image 700 provides a GUI that allows the user to input at least one value to adjust the hue of the input image to any desired tone. The detailed setting image 700 includes a preview image 710, a setting value display image 720, an OK button 730, and a reset button 740. The detailed setting image 700 corresponds to "the third setting image".

[0126] The setting value display image 720 displays the hue setting value determined based on the operation prior to the third operation of pressing any one of the detailed setting buttons 380, 460, 570, and 630. The setting value display image 720 includes multiple numerical input areas 721 associated with multiple setting items. For example, the multiple setting items include settings corresponding to seven colors: "Red," "Green," "Blue," "Cyan," "Magenta," "Yellow," and "White."

[0127] Multiple numeric input areas 721 represent values ​​corresponding to their respective associated setting items. For example, the numeric input area 721 associated with the setting item "Red" represents the value corresponding to "Red" from the values ​​included in the hue setting determined based on the operations prior to the third operation. The numeric input area 721 associated with the setting item "Green" represents the value corresponding to "Green" from the aforementioned hue setting values. The numeric input area 721 associated with the setting item "Blue" represents the value corresponding to "Blue" from the aforementioned hue setting values. The values ​​shown in the numeric input areas 721 are overwritten by the user's input of values.

[0128] The numerical input area 721 associated with the setting item "Red" corresponds to "the first numerical input area representing the numerical value corresponding to the first setting item". The numerical input area 721 associated with the setting item "Green" corresponds to "the second numerical input area representing the numerical value corresponding to the second setting item". The numerical input area 721 associated with the setting item "Blue" corresponds to "the third numerical input area representing the numerical value corresponding to the third setting item".

[0129] For example, after selecting the first candidate image 310 from the first image type selection image 300 through the first operation, if the first processor 15 accepts the third operation of pressing the detailed setting button 460 included in the brightness selection image 400, it reads the first tone setting value from the first memory 14 and generates a setting value display image 720 that displays the first tone setting value. In this case, for example, the numerical input area 721 associated with the setting item "Red" represents the value corresponding to "Red" among the values ​​included in the first tone setting value.

[0130] For example, after the first processor 15 selects the second candidate image 320 from the first image type selection image 300 through the first operation, and then accepts the third operation of pressing the detailed setting button 460 included in the brightness selection image 400, it reads the second tone setting value from the first memory 14 and generates a setting value display image 720 that displays the second tone setting value. In this case, for example, the numerical input area 721 associated with the setting item "Red" represents the value corresponding to "Red" among the values ​​included in the second tone setting value.

[0131] like Figure 11 As shown, among the multiple numeric input areas 721 that include at least a first numeric input area, a second numeric input area, and a third numeric input area, the numeric input area 722 representing a value different from the initial value has a different display mode than the other numeric input areas 721. For example, the numeric input area 722 representing a value different from the initial value is surrounded by a rectangular frame image with a specified color. Alternatively, the inner color of the numeric input area 722 representing a value different from the initial value can also be a different color from the inner color of the other numeric input areas 721. The numeric input area 722 representing a value different from the initial value is not limited to these display modes; it can be any display mode as long as it is more conspicuous than the other numeric input areas 721.

[0132] Preview image 710 is a preview image of an input image whose hue has been adjusted based on the hue setting values ​​displayed in setting value display image 720. OK button 730 is an image (icon) used to notify the first processor 15 that detailed settings have been completed. For example, OK button 730 contains the string "OK". Reset button 740 is an image (icon) used to instruct the first processor 15 to reset the hue setting values ​​displayed in setting value display image 720 to their default values ​​(initial values). For example, reset button 740 contains the string "Reset".

[0133] In addition, Figure 11In the preview image 710, the preview image 710 is represented as a black and white image, but in the actual detailed settings image 700, the preview image 710 is a color image of the input image whose hue has been adjusted based on the hue settings displayed in the settings display image 720.

[0134] like Figure 4 As shown, during the display of the detailed setting image 700, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether to accept a fourth operation (step S19) for inputting at least one value for adjusting the input image. Accepting the fourth operation includes accepting an operation to rewrite the tone setting value displayed in the setting value display image 720 included in the detailed setting image 700.

[0135] If the first processor 15 determines that the fourth operation has been accepted (step S19: Yes), it updates the detailed setting image 700 based on the value input through the fourth operation (step S20). Specifically, in step S20, the first processor 15 rewrites the tone setting value displayed in the setting value display image 720 included in the detailed setting image 700 with the value input through the fourth operation. In addition, the first processor 15 replaces the preview image 710 included in the detailed setting image 700 with a preview image of the input image whose tone has been readjusted based on the value input through the fourth operation.

[0136] After updating the detailed setting image 700 as described above, the first processor 15 proceeds to step S21. On the other hand, if the first processor 15 determines that the fourth operation has not been accepted (step S19: No), it skips step S20 and proceeds to step S21.

[0137] When proceeding to step S21, the first processor 15 determines whether the operation of pressing the reset button 740 was accepted during the display of the detailed setting image 700 (step S21). If the first processor 15 determines that the operation of pressing the reset button 740 was accepted (step S21: yes), it resets the hue setting value displayed in the setting value display image 720 to the default value (initial value) (step S22).

[0138] The first processor 15 updates the detailed setting image 700 based on the tone setting values ​​reset to default values ​​(step S23). Specifically, in step S23, the first processor 15 rewrites the tone setting values ​​displayed in the setting value display image 720 included in the detailed setting image 700 to the default values. Additionally, the first processor 15 replaces the preview image 710 included in the detailed setting image 700 with a preview image of the input image whose tone has been readjusted based on the tone setting values ​​reset to default values. After step S23 is completed, the first processor 15 returns to step S19.

[0139] On the other hand, if the first processor 15 determines that the operation of pressing the reset button 740 has not been accepted (step S21: No), it determines whether the operation of pressing the confirm button 730 has been accepted (step S24). If the first processor 15 determines that the operation of pressing the confirm button 730 has not been accepted (step S24: No), it returns to step S19. If the first processor 15 determines that the operation of pressing the confirm button 730 has been accepted (step S24: Yes), it proceeds to step S19. Figure 3 Step S13 in the flowchart.

[0140] When transitioning to step S13, as already explained, the first processor 15 causes the first display device 12 to display an application window containing the final confirmation image 600. Specifically, in the case of transitioning from step S24 to step S13, the final preview image 610 included in the final confirmation image 600 is a preview image of an input image whose hue has been adjusted based on the hue setting value displayed in the setting value display image 720 when the OK button 730 was pressed during the display of the detailed setting image 700.

[0141] The following describes the processing performed by the first processor 15 when it accepts the operation of selecting the second option image 220 during the display adjustment method selection of image 200.

[0142] like Figure 2 As shown, if the first processor 15 determines that it has performed an operation to select the second option image 220 during the display adjustment method selection of image 200 (step S2: No), it proceeds to... Figure 5 Step S25 in the flowchart. In other words, if the first processor 15 determines that it has accepted the operation of selecting the second option, namely "reading professional data" as the tone adjustment method, it proceeds to step S25. The operation of selecting the second option image 220 means, for example, that the user clicks the second option image 220 with the mouse 11b.

[0143] like Figure 5 As shown, when the process moves to step S25, the first processor 15 causes the first display device 12 to display an application window containing the retrieval method selection image 800 (step S25).

[0144] Figure 12 This is an example of a search method selection image 800. The search method selection image 800 is an image that requests the user to select data (tone setting values) for a professional user. The search method selection image 800 includes a first option image 810 representing the first option and a second option image 820 representing the second option.

[0145] The first option image 810 contains a string corresponding to the first option. As an example, the string corresponding to the first option is "Search by content name". As will be described later, when the first processor 15 accepts the operation of selecting the first option image 810, it performs the process of retrieving the data of the professional user based on the content name entered by the user.

[0146] The second option image 820 contains a string corresponding to the second option. As an example, the string corresponding to the second option is "Search by type". As described later, when the first processor 15 receives the operation of selecting the second option image 820, it performs the process of retrieving the data of the professional user based on the image type selected by the user.

[0147] like Figure 5 As shown, during the display of the search method selection image 800, the first processor 15 determines whether the operation of selecting the first option image 810 has been accepted based on the first operation signal input from the first input device 11 (step S26). In other words, the first processor 15 determines whether the operation of selecting the first option, namely "search by content name", as the search method has been accepted.

[0148] If the first processor 15 determines that the operation of selecting the first option image 810 has been accepted (step S26: Yes), it causes the first display device 12 to display an application window containing the content name input image 900 (step S27). The operation of selecting the first option image 810 means, for example, that the user clicks the first option image 810 with the mouse 11b.

[0149] Figure 13 This is an example diagram representing a content name input image 900. The content name input image 900 is an image that requests the user to input a content name. The content name input image 900 includes a character input area 910 for inputting the content name.

[0150] like Figure 5 As shown, during the display of the content name input image 900, the first processor 15 determines whether the operation of inputting the content name has been accepted based on the first operation signal input from the first input device 11 (step S28). If the first processor 15 determines that the operation of inputting the content name has not been accepted (step S28: No), the processing of step S28 is repeated until the operation of inputting the content name is accepted.

[0151] On the other hand, when the first processor 15 determines that the operation of inputting content name has been accepted (step S28: Yes), it accesses the Internet via the first communication unit 13 and downloads data of multiple professional users retrieved using the input content name from the Internet server (step S29).

[0152] After downloading user data from multiple processors, the first processor 15 displays an application window containing the user-selected image 1000 on the first display device 12 (step S30).

[0153] Figure 14 This is an example diagram representing a user selecting image 1000. User-selected image 1000 is an image that requests a user to select one of multiple professional user data. User-selected image 1000 includes a first user candidate image 1010, a second user candidate image 1020, a selection box 1030, and a confirmation button 1040.

[0154] The first user candidate image 1010 is a preview image of an input image whose hue has been adjusted based on data (hue settings) from a professional user named "AAAA". The second user candidate image 1020 is a preview image of an input image whose hue has been adjusted based on data (hue settings) from a professional user named "BBBB". As an example, in the user-selected image 1000, the first user candidate image 1010 and the second user candidate image 1020 are displayed in a ranking format. The data from the professional user named "AAAA" is ranked first. The data from the professional user named "BBBB" is ranked second. The ranking is set, for example, according to the cumulative amount selected by users using the image display system 1 so far, from most to least.

[0155] In addition, Figure 14 In the text, the first user candidate image 1010 and the second user candidate image 1020 are represented as black and white images. However, in the actual user-selected image 1000, the first user candidate image 1010 and the second user candidate image 1020 are color images of the input images whose tones have been adjusted based on data from different professional users.

[0156] Selection box 1030 is a rectangular frame image used to select one of the first user candidate image 1010 and the second user candidate image 1020. The first processor 15 identifies the user candidate image surrounded by selection box 1030 among the first user candidate image 1010 and the second user candidate image 1020 as the user candidate image selected by the user (data of professional users).

[0157] The Decision button 1040 is an image (icon) used to notify the first processor 15 of the data of a professional user who has decided on the tone setting values ​​to be used as the input image. As an example, the Decision button 1040 contains the string "Decision".

[0158] like Figure 5As shown, during the display of the user-selected image 1000, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether the operation of selecting one of the first user candidate image 1010 and the second user candidate image 1020 has been accepted (step S31). In other words, the first processor 15 determines whether the operation of selecting one of the professional users named "AAAA" and "BBBB" has been accepted.

[0159] The operation of selecting one of the first user candidate image 1010 and the second user candidate image 1020 means, for example, that the user uses the mouse 11b to place the selection box 1030 at the position of one of the first user candidate image 1010 and the second user candidate image 1020, and then clicks the confirm button 1040.

[0160] If the first processor 15 determines that the operation of selecting one of the first user candidate image 1010 and the second user candidate image 1020 has not been accepted (step S31: No), the first processor 15 repeats the processing of step S31 until the operation of selecting one of the first user candidate image 1010 and the second user candidate image 1020 is accepted.

[0161] On the other hand, if the first processor 15 determines that it has accepted the operation of selecting one of the first user candidate image 1010 and the second user candidate image 1020 (step S31: Yes), it transfers to Figure 3 Step S13 in the flowchart.

[0162] When transitioning to step S13, as already explained, the first processor 15 causes the first display device 12 to display an application window containing the final confirmation image 600. In the case of transitioning from step S31 to step S13, the final confirmation image 600 includes a final preview image 610 that is a preview image of an input image whose hue has been adjusted based on the data (hue setting value) of a professional user selected during the display of the user-selected image 1000.

[0163] If the first processor 15 determines that no operation to select the first option image 810 was processed during the display of the search method selection image 800 (step S26: No), it proceeds to step S32. That is, if the first processor 15 determines that an operation to select the second option image 820 was processed during the display of the search method selection image 800, it proceeds to step S32.

[0164] In other words, if the first processor 15 determines that it has accepted the operation of selecting the second option, namely "search by type", as the search method, it proceeds to step S32. The operation of selecting the second option image 820 means, for example, that the user clicks the second option image 820 with the mouse 11b.

[0165] When the process moves to step S32, the first processor 15 causes the first display device 12 to display an application window containing the second image type selection image 1100 (step S32).

[0166] Figure 15 This is an example of a second image type selection image 1100. The second image type selection image 1100 is an image that requests the user to select a type name as the search object. The second image type selection image 1100 includes a first type selection button 1110, a second type selection button 1120, a third type selection button 1130, a fourth type selection button 1140, a fifth type selection button 1150, and a sixth type selection button 1160.

[0167] The first type selection button 1110 is an image (icon) used to notify the first processor 15 that "Action" has been selected as the type name. For example, the first type selection button 1110 contains the string "Action". The second type selection button 1120 is an image (icon) used to notify the first processor 15 that "Fantasy" has been selected as the type name. For example, the second type selection button 1120 contains the string "Fantasy".

[0168] The third type selection button 1130 is an image (icon) used to notify the first processor 15 that "SF" has been selected as the type name. For example, the third type selection button 1130 contains the string "SF". The fourth type selection button 1140 is an image (icon) used to notify the first processor 15 that "Adventure" has been selected as the type name. For example, the fourth type selection button 1140 contains the string "Adventure".

[0169] The fifth type selection button 1150 is an image (icon) used to notify the first processor 15 that "Sports" has been selected as the type name. For example, the fifth type selection button 1150 contains the string "Sports". The sixth type selection button 1160 is an image (icon) used to notify the first processor 15 that "Suspense" has been selected as the type name. For example, the sixth type selection button 1160 contains the string "Suspense".

[0170] like Figure 5 As shown, during the display of the second image type selection image 1100, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether an operation of pressing one of the first type selection buttons 1110 to the sixth type selection button 1160 has been accepted (step S33). In other words, the first processor 15 determines whether an operation of selecting a type name as the search object has been accepted.

[0171] The operation of pressing one of the Type 1 selection buttons 1110 to the Type 6 selection buttons 1160 is, for example, the user clicking one of the Type 1 selection buttons 1110 to the Type 6 selection buttons 1160 using mouse 11b.

[0172] If the first processor 15 determines that the operation of pressing one of the first type selection buttons 1110 to the sixth type selection buttons 1160 has not been accepted (step S33: No), the first processor 15 repeats the processing of step S33 until the operation of pressing one of the first type selection buttons 1110 to the sixth type selection buttons 1160 has been accepted.

[0173] On the other hand, if the first processor 15 determines that an operation has been accepted for pressing one of the first type selection buttons 1110 to the sixth type selection buttons 1160 (step S33: Yes), it accesses the Internet via the first communication unit 13 and downloads data of multiple professional users retrieved according to the selected type name from the Internet server (step S34). After step S34 is completed, the first processor 15 proceeds to the above-described step S30.

[0174] (Effects of this implementation method)

[0175] The image display method of this embodiment is realized through the operation of the image display system 1 described above. That is, the image display method of this embodiment includes: displaying a first image type selection image 300 (first setting image) containing a first candidate image 310 (first image) representing a first tone setting value (first setting value) and a second candidate image 320 (second image) representing a second tone setting value (second setting value); accepting a first operation to select one of the first candidate image 310 and the second candidate image 320; if the first operation is accepted, displaying a brightness selection image 400 (second setting image) containing a fifth candidate image 410 (third image) representing a fifth tone setting value (third setting value) and a sixth candidate image 420 (fourth image) representing a sixth tone setting value (fourth setting value); accepting a second operation to select one of the fifth candidate image 410 and the sixth candidate image 420; and displaying an input image adjusted based on the first operation and the second operation.

[0176] According to the image display method of this embodiment described above, by performing an operation that includes at least two stages, namely selecting one of the first candidate image 310 and the second candidate image 320 from the first image type selection image 300, and selecting one of the fifth candidate image 410 and the sixth candidate image 420 from the brightness selection image 400, the user can adjust the input image to the desired tone in detail.

[0177] Therefore, the image display method according to this embodiment can provide a GUI that can respond to user requests such as wanting to adjust the image in more detail through an intuitive method, thereby improving user convenience.

[0178] In the image display method of this embodiment, the brightness selection image 400 (second setting image) further includes a detailed setting button 460 (fifth image), and the image display method further includes: during the display of the brightness selection image 400, accepting a third operation of selecting the detailed setting button 460; if the third operation is accepted, accepting a fourth operation of inputting at least one value for adjusting the input image; and displaying the input image adjusted based on the value input by the fourth operation.

[0179] Based on this image display method, a GUI that can adjust the hue of the input image to any hue can be provided by allowing the user to input at least one value for adjusting the input image.

[0180] The image display method of this embodiment further includes: displaying a first tone setting value (first setting value) when a third operation is performed after a first candidate image 310 (first image) has been selected through a first operation; and displaying a second tone setting value (second setting value) when a third operation is performed after a second candidate image 320 (second image) has been selected through a first operation. The fourth operation includes: performing an operation to rewrite the first tone setting value when a third operation is performed after a first candidate image 310 has been selected through a first operation; and performing an operation to rewrite the second tone setting value when a third operation is performed after a second candidate image 320 has been selected through a first operation.

[0181] According to this image display method, the color tone setting value determined by the first operation before the third operation of pressing the detailed setting button 460 is displayed, so the user can easily grasp the specific value of the color tone setting determined at the time of the third operation. In addition, as a result, the user's convenience is improved when performing the fourth operation to rewrite the displayed color tone setting value.

[0182] The image display method of this embodiment further includes: when the third operation is received, displaying a detailed setting image 700 (third setting image) that includes a first value input area representing a value corresponding to the first setting item, a second value input area representing a value corresponding to the second setting item, and a third value input area representing a value corresponding to the third setting item, wherein the value input area representing a value different from the initial value in the first, second, and third value input areas is displayed in a different manner than the other value input areas.

[0183] According to this image display method, users can easily identify the values ​​in the tone setting determined at the time of the third operation that differ from the initial value. As a result, user convenience can be further improved when performing the fourth operation to rewrite the displayed tone setting value.

[0184] The image display method of this embodiment further includes: displaying a brightness selection image 400 (a second setting image) when a first candidate image 310 (a first image) is selected through a first operation; displaying an adjustment color selection image 500 (a fourth setting image) when a second operation is received; and displaying an adjustment color selection image 500 when a second candidate image 320 (a second image) is selected through a first operation.

[0185] For example, as described above, when the first operation of selecting the second candidate image 320 is received, that is, when the first operation of selecting "cinema" as the image type is received, the hue of the input image is adjusted to darken by the second hue setting value. In this case, it is not necessary to display the brightness selection image 400 to allow the user to select the brightness of the input image.

[0186] Therefore, according to the image display method described above, when the first operation of selecting the second candidate image 320 is accepted, the display of the brightness selection image 400 is skipped and the color adjustment selection image 500 is displayed instead, thereby improving the user's work efficiency.

[0187] In the image display method of this embodiment, the first candidate image 310 (first image) includes a preview image of the input image adjusted based on a first hue setting value (first setting value). According to such an image display method, the user can visually understand how to adjust the hue of the input image based on the first hue setting value, thus improving user convenience.

[0188] In the image display method of this embodiment, the first candidate image 310 (first image) contains a string (“dynamic”) corresponding to the first tone setting value (first setting value).

[0189] This image display method allows users to visually understand how to adjust the tone of the input image based on the first tone setting value, thus improving user convenience.

[0190] The image display method of this embodiment further includes: before displaying the first image type selection image 300 (first setting image), displaying an adjustment method selection image 200 (selection image) that includes a first option image 210 (sixth image) representing a first option and a second option image 220 (seventh image) representing a second option; displaying the first image type selection image 300 when an operation to select the first option image 210 is received; and receiving a tone setting value for adjusting the input image from a server when an operation to select the second option image 220 is received.

[0191] This image display method can present the first and second options as methods for adjusting the input image to the user, thus improving user convenience.

[0192] The image display system 1 of this embodiment includes a first image display device 10 and a second image display device 20, which is different from the first image display device 10. The first image display device 10 includes a first display device 12 for displaying images and a first processor 15 for controlling the first display device 12. The second image display device 20 includes a second display device 22 for displaying images and a second processor 26 for controlling the second display device 22. The first processor 15 performs the following processing: causing the first display device 12 to display a first image type selection image 300 (first setting image) containing a first candidate image 310 (first image) representing a first hue setting value (first setting value) and a second candidate image 320 (second image) representing a second hue setting value (second setting value); accepting a first operation to select one of the first candidate image 310 and the second candidate image 320; if the first operation is accepted, displaying a brightness selection image 400 (second setting image) containing a fifth candidate image 410 (third image) representing a fifth hue setting value (third setting value) and a sixth candidate image 420 (fourth image) representing a sixth hue setting value (fourth setting value); and accepting a second operation to select one of the fifth candidate image 410 and the sixth candidate image 420. The second processor 26 performs the following processing: causing the second display device 22 to display an input image adjusted based on the first operation and the second operation.

[0193] The image display system 1 according to this embodiment can provide a GUI that can respond to user requests such as wanting to adjust the image in more detail through an intuitive method, thereby improving user convenience.

[0194] [Second Implementation]

[0195] Next, the second embodiment of this disclosure will be described.

[0196] In the second embodiment, the structure of the image display system 1 is the same as that in the first embodiment. However, the operation of the image display system 1 differs from that in the first embodiment; therefore, the operation of the image display system 1 in the second embodiment will be described below. In the following description, content repeated in the first embodiment is omitted.

[0197] like Figure 2 As shown, when the first processor 15 starts the image adjustment process, it first displays the application window containing the image 200 with the adjustment method selection as a GUI on the first display device 12 (step S1).

[0198] During the display of the adjustment method selection image 200, the first processor 15 determines whether the operation of selecting the first option image 210 has been accepted based on the first operation signal input from the first input device 11 (step S2).

[0199] If the first processor 15 determines that it has accepted the operation of selecting the first option image 210 (step S2: yes), it skips the step. Figure 2 The processing of steps S3 to S6 in the flowchart causes the first display device 12 to display an application window containing the brightness selection image 400 (step S7). Thus, in the second embodiment, steps S3 to S6 are omitted. Figure 2 The processing of steps S3 to S6 in the flowchart.

[0200] On the other hand, if the first processor 15 determines that no operation to select the first option image 210 was performed during the period of selecting image 200 in the display adjustment method (step S2: No), it transfers to Figure 5 Step S25 in the flowchart. That is, when the first processor 15 determines that it has accepted the operation of selecting the second option image 220, it proceeds to step S25. In other words, when the first processor 15 determines that it has accepted the operation of selecting the second option, namely "reading professional data" as the tone adjustment method, it proceeds to step S25.

[0201] During the display of the brightness selection image 400, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether a second operation (step S8) has been accepted to select one of the fifth candidate image 410 and the sixth candidate image 420. In other words, the first processor 15 determines whether a second operation has been accepted to select either "bright" or "dark" as the brightness of the input image.

[0202] If the first processor 15 determines that the second operation of selecting one of the fifth candidate image 410 and the sixth candidate image 420 has not been accepted (step S8: No), it determines whether the third operation of pressing the detailed settings button 460 has been accepted (step S9). If the first processor 15 determines that the third operation of pressing the detailed settings button 460 has been accepted (step S9: Yes), it proceeds to... Figure 4 Step S18 in the flowchart.

[0203] If the first processor 15 determines that the third operation of pressing the detailed settings button 460 has not been accepted (step S9: No), it returns to step S8. Additionally, although in Figure 2 Not shown in the figure, but if the first processor 15 determines that the operation of pressing the return operation button 450 was performed during the display of the brightness selection image 400, it returns to step S1 and returns the image displayed in the application window from the brightness selection image 400 to the immediately preceding adjustment method selection image 200.

[0204] If the first processor 15 determines that the second operation of selecting one of the fifth candidate image 410 and the sixth candidate image 420 has been accepted (step S8: Yes), it proceeds to... Figure 3 Step S10 in the flowchart.

[0205] like Figure 3 As shown, when transitioning to step S10, the first processor 15 causes the first display device 12 to display an application window containing the color selection image 500 (step S10).

[0206] During the display of the color selection image 500, the first processor 15 determines, based on the first operation signal input from the first input device 11, whether a fifth operation (step S11) to select one of the seventh candidate images 510 to the ninth candidate images 530 has been accepted. In other words, the first processor 15 determines whether a fifth operation to select the hue to be emphasized from the three hues of red, blue, and green in the input image has been accepted.

[0207] If the first processor 15 determines that the fifth operation of selecting one of the seventh candidate images 510 to the ninth candidate images 530 has not been accepted (step S11: No), it determines whether the operation of pressing the detailed settings button 570 has been accepted (step S12). If the first processor 15 determines that the operation of pressing the detailed settings button 570 has been accepted (step S12: Yes), it proceeds to... Figure 4 Step S18 in the flowchart.

[0208] If the first processor 15 determines that the operation of pressing the detailed settings button 570 has not been accepted (step S12: No), it returns to step S11. Additionally, although in Figure 3 Not shown in the figure, but if the first processor 15 determines that the operation of pressing the return operation button 560 was performed during the display of the adjustment color selection image 500, it returns to step S7 and returns the image displayed in the application window from the adjustment color selection image 500 to the immediately preceding brightness selection image 400.

[0209] If the first processor 15 determines that it has accepted the fifth operation of selecting one of the seventh candidate images 510 to the ninth candidate images 530 (step S11: yes), it causes the first display device 12 to display an application window containing the final confirmation image 600 (step S13).

[0210] During the display of the final confirmation image 600, the first processor 15 determines whether the operation of pressing the OK button 620 has been accepted based on the first operation signal input from the first input device 11 (step S14). If the first processor 15 determines that the operation of pressing the OK button 620 has not been accepted (step S14: No), it determines whether the operation of pressing the detailed settings button 630 has been accepted (step S15).

[0211] If the first processor 15 determines that the operation of pressing the detailed setting button 630 has been accepted (step S15: Yes), it proceeds to... Figure 4 Step S18 in the flowchart. If the first processor 15 determines that the operation of pressing the detailed setting button 630 has not been accepted (step S15: No), it returns to step S14.

[0212] When the first processor 15 determines that the operation of pressing the OK button 620 has been accepted (step S14: Yes), it adjusts the tone of the input image based on the operation accepted by the user (step S16). For example, if step S11 is executed and then step S13 is executed, the first processor 15 adjusts the tone of the input image based on the second operation and the fifth operation.

[0213] Specifically, for example, if the fifth candidate image 410 is selected through the second operation and the seventh candidate image 510 is selected through the fifth operation, the first processor 15 reads the fifth tone setting value and the seventh tone setting value from the first memory 14. This situation can be described as a case where "brightness" is selected as the brightness of the input image through the second operation and "red tone" is selected as the tone to be emphasized through the fifth operation. In such a case, the first processor 15 rewrites the image data representing the input image based on the fifth tone setting value and the seventh tone setting value, thereby adjusting the tone of the input image.

[0214] After adjusting the tone of the input image as described above, the first processor 15 sends the tone-adjusted input image to the second image display device 20 via the first communication unit 13 (step S17). Specifically, in step S17, the first processor 15 sends an image signal containing image data rewritten based on the tone setting value read from the first memory 14 to the second image display device 20 via the first communication unit 13.

[0215] When the second processor 26 of the second image display device 20 receives an image signal from the first image display device 10 via the second communication unit 23, it controls the second display device 22 to project an image light L representing an input image with adjusted hue, based on the image data contained in the image signal. As a result, the input image with adjusted hue according to the user's operation is displayed on the projection surface 100.

[0216] In the second embodiment, Figure 4 The processing of steps S18 to S24 in the flowchart and Figure 5 The processing of steps S25 to S34 in the flowchart is the same as that in the first embodiment, so the description of these processes is omitted.

[0217] The above describes one embodiment of the present disclosure, but the technical scope of the present disclosure is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present disclosure. Hereinafter, variations of the present disclosure will be described.

[0223] For example, the image display device is a projector, such as the second image display device 20. When the image display device is a projector, the display device is a projection device, such as the second display device 22. Furthermore, the processor executes both the processing performed by the first processor 15 and the processing performed by the second processor 26.

[0224] (3) In the above embodiments, a second image display device 20 as a projector was exemplified, but the second image display device of this disclosure is not limited to a projector.
