[0002] In modern computing environments, multiple displays, particularly dual-monitor setups, are widely used. Dual-monitor environments contribute to increased productivity in various tasks such as multitasking, graphics work, and data analysis, and are being adopted in diverse application fields, including personal computers (PCs), professional workstations, and gaming environments.

[0003] However, in dual-monitor environments in related fields, each display device operates independently, and the image quality characteristics of each monitor (e.g., color temperature, brightness, contrast ratio, color gamut, etc.) may differ. This can lead to issues such as color inconsistencies and differences in brightness and contrast ratio between the dual monitors.

[0004] Manual image quality calibration technologies in related fields are primarily designed for single-monitor environments. Consequently, performing manual calibration in a dual-monitor setting is time-consuming, and general users without specialized knowledge find it difficult to set optimized image quality. Therefore, a method is needed to automatically perform image quality calibration in a dual-monitor environment.

[0035] FIG. 1 is a drawing showing an electronic device, a plurality of display devices, and an external device according to one embodiment.

[0036] Referring to FIG. 1, an electronic device (100) according to one embodiment may be connected to a plurality of display devices through an input / output interface. For example, the plurality of display devices may include a first display device (210) and a second display device (220). However, it is not limited thereto, and the electronic device (100) may be connected to a larger number of display devices.

[0037] An electronic device (100) according to one embodiment may be implemented in various forms such as a desktop, a laptop computer, a tablet PC, a mobile phone, etc. However, it is not limited thereto.

[0038] The electronic device (100) may be connected to a first display device (210) and a second display device (220) via a cable, and each of the electronic device (100), the first display device (210), and the second display device (220) may include one or more ports for cable connection. The one or more ports may include digital input interfaces, for example, an HDMI port, a DisplayPort, etc., but are not limited thereto.

[0039] The electronic device (100), the first display device (210), and the second display device (220) can be connected via DDC / CI (Display Data Channel / Command Interface) communication through an HDMI port or a display port. DDC communication may be a communication protocol that transmits function and resolution information supported by the first and second display devices (210, 220) to the electronic device (100). The first display device (210) and the second display device (220) can transmit EDID (Extended Display Identification Data) information of the first display device (210) and the second display device (220) to the electronic device (100) using DDC communication.

[0040] Additionally, the electronic device (100) can control the settings of the first display device (210) or the second display device (220) by transmitting commands to the first display device (210) or the second display device (220) via CI communication. For example, the electronic device (100) can change the settings of the first display device (210) or the second display device (220) using software without using the OSD (On-Screen Display) menu of the first display device (210) or the second display device (220). However, it is not limited thereto.

[0041] A first display device (210) and a second display device (220) according to one embodiment may include various types of electronic devices including a display. The first display device (210) and the second display device (220) may be implemented in various forms such as a TV, monitor, smart monitor, mobile phone, tablet PC, digital camera, camcorder, laptop computer, etc. However, they are not limited thereto.

[0042] When a first display device (210) and a second display device (220) according to one embodiment are connected to an electronic device (100) and used as a dual monitor, it is necessary to match the screen of the first display device (210) and the screen of the second display device (220) to the same color and brightness. Calibration may be performed to match the screen of the first display device (210) and the screen of the second display device (220) to the same color and brightness. At this time, the first display device (210) may be a reference display device, and the second display device (220) may be a target display device that is the subject of calibration to match the screen of the reference display device. However, it is not limited thereto.

[0043] An electronic device (100) according to one embodiment can perform calibration to match the screen of a first display device (210) and the screen of a second display device (220) to the same color by using an external device (300) including a camera.

[0044] An electronic device (100) according to one embodiment can communicate with an external device (300) through wireless communication.

[0045] For example, the electronic device (100) and the external device (300) may include at least one communication module that performs communication according to communication standards such as Bluetooth, Wi-Fi, BLE (Bluetooth Low Energy), NFC / RFID, Wi-Fi Direct, UWB, ZIGBEE, the Internet, 3G, 4G, 5G and / or 6G, and may be connected through the communication module. However, they are not limited thereto.

[0046] An external device (300) according to one embodiment may be implemented as various electronic devices such as a mobile phone, tablet PC, digital camera, camcorder, laptop computer, camcorder, wearable device, etc. The external device (300) may be a mobile device including a camera. For example, the external device (300) may use a camera to capture the screen of a first display device (210) and obtain color data (first color data) for the screen of the first display device (210). Additionally, the external device (300) may use a camera to capture the screen of a second display device (220) and obtain color data (second color data) for the screen of the second display device (220).

[0047] The external device (300) can transmit the acquired first color data and second color data to the electronic device (100).

[0048] The electronic device (100) can adjust at least one parameter related to the screen of the second display device (220) based on the first color data and second color data received from the external device (300) so that the color of the screen of the first display device (210) and the color and brightness of the screen of the second display device (220) become the same.

[0049] In the case where the manufacturers or models of the first display device (210) and the second display device (220) according to one embodiment are different, the first display device (210) and the second display device (220) may have different screen menus configured. Additionally, the range in which color values ​​can be adjusted may differ for each screen menu of the first display device (210) and the second display device (220). Accordingly, it may be difficult to make the color of the first display device and the color of the second display device identical by only correcting the color values. This will be explained in detail with reference to FIG. 2.

[0050] FIG. 2 is a graph showing the changeable range of color coordinates for each color temperature menu according to one embodiment.

[0051] According to one embodiment, the color temperature of a screen is an indicator representing the color of light appearing on the screen. The higher the color temperature of the screen, the cooler (blue) the tone of the light emitted from the screen may appear, and the lower the color temperature, the warmer (red / yellow) the tone of the light emitted from the screen may appear. The screen setting menu of the display may include a color temperature menu. For example, the color temperature menu may include a first mode ("Cool"), a second mode ("Standard"), a third mode ("Warm 1"), and a fourth mode ("Warm 2"). However, this is for convenience of explanation, and the color temperature menu may include fewer or more modes.

[0052] Referring to FIG. 2, when the color temperature menu is set to the first mode ("Cool"), the color coordinate values ​​can be changed within the first range (201). For example, when the color temperature menu is set to the first mode ("Cool"), the color values ​​of the screen can be changed only within the first range (201).

[0053] Additionally, when the color temperature menu is set to the fourth mode ("Warm 2"), the color coordinate values ​​may be changed within the second range (204). For example, when the color temperature menu is set to the fourth mode ("Warm 2"), the color values ​​of the screen may be changed only within the second range (204).

[0054] Accordingly, when the color value of the screen of the first display device (210) is the first value (203) and the color temperature menu of the second display device (220) is set to the first mode ("Cool"), the color value of the screen of the second display device (220) cannot be calibrated to the first value (203) even if the color value of the second display device (220) is adjusted. The color value of the second display device (220) can be calibrated to the second value (205) that is most similar to the first value (203) within the first range (201).

[0055] Additionally, if the color value of the screen of the first display device (210) is the first value (203) and the color temperature menu of the second display device (220) is set to the fourth mode ("Warm 2"), the color value of the screen of the second display device (220) cannot be calibrated to the first value (203) even if the color value of the second display device (220) is adjusted. The color value of the second display device (220) can be calibrated to the third value (205) that is most similar to the first value (203) within the second range (204). In this way, if calibration is performed without optimizing the screen menu of the second display device (220), accurate calibration of the second display device (220) may not be performed.

[0056] Accordingly, the electronic device (100) according to one embodiment can improve the efficiency and accuracy of calibration by optimizing the screen menu of the second display device (220) for the color data of the screen of the first display device (210) and then performing screen calibration of the second display device (220).

[0057] This will be explained in detail with reference to the drawings below.

[0058] FIG. 3 is a flowchart illustrating the operation method of an electronic device according to one embodiment.

[0059] Referring to FIG. 3, an electronic device according to one embodiment can acquire first color data of the screen of a first display device (S310).

[0060] A first display device (210) according to one embodiment may be a reference display device. For example, a screen displayed on the first display device (210) may be a screen that serves as a reference for screen calibration.

[0061] The external device (300) can use a camera included in the external device (300) to capture the screen of the first display device (210) and obtain first color data of the screen of the first display device (210). At this time, the first color data may include RGB values.

[0062] The external device (300) can transmit the first color data to the electronic device (100). At this time, the first color data transmitted to the electronic device (100) may be raw data before image processing is performed in the camera.

[0063] An electronic device (100) according to one embodiment can change screen setting information of a second display device (220) (S320).

[0064] A second display device (220) according to one embodiment may be a target display device that is subject to screen calibration to match the same color as the screen of a reference display device.

[0065] An electronic device (100) and a second display device (220) according to one embodiment can be connected to each other through an input / output interface including HDMI or a display port (DP), and can transmit and receive data using DDC / CI communication.

[0066] For example, the electronic device (100) can change at least one setting included in the screen menu of the second display device (220) using DDC / CI communication. For example, the screen menu may include menus that can change picture mode, brightness, contrast ratio, color temperature, color space, etc. The picture mode menu is a menu provided to select an appropriate mode according to the type of content or viewing environment, and each mode may include pre-set values ​​to quickly and easily adjust the image quality of the screen. For example, the picture mode menu may include standard mode, dynamic mode, movie mode, sports mode, game mode, photo mode, eco mode, user mode, etc. However, it is not limited thereto.

[0067] The Brightness menu allows you to adjust the intensity of the backlight (light source) emitted from the screen, thereby controlling the degree of brightness and darkness of the image. The Contrast Ratio menu may be a menu that allows you to adjust the brightness difference between the brightest white and the darkest black on the screen. The Color Temperature menu allows you to adjust the color temperature of the screen, and the Color Space menu may be a menu that allows you to set a coordinate system defining the range of colors (color gamut) that the screen can display. However, it is not limited to these.

[0068] The electronic device (100) can change setting information for at least one of picture mode, brightness, contrast ratio, color temperature, and color space included in the screen menu of the second display device (220). As at least one setting information for the screen menu of the second display device (220) is changed, the color and brightness of the screen displayed on the second display device (220) may be changed.

[0069] An electronic device (100) according to one embodiment can acquire second color data of changed screens of a second display device (220) (S330).

[0070] For example, the external device (300) can use a camera included in the external device (300) to capture the screen of the second display device (220) whenever the screen setting information of the second display device (220) is changed. The external device (300) can acquire second color data of the screens of the second display device (220) corresponding to the changed screen setting information. At this time, the second color data may include RGB values.

[0071] The external device (300) can transmit second color data to the electronic device (100). At this time, the second color data transmitted to the electronic device (100) may be raw data before image processing is performed in the camera.

[0072] An electronic device (100) according to one embodiment can identify any one of a plurality of screen setting information based on first color data and second color data (S340).

[0073] The electronic device (100) can obtain first color coordinates corresponding to the first color data by converting the first color data from RGB values ​​to xyY values.

[0074] For example, the electronic device (100) can convert the first color data obtained in step 310 (S310) from RGB values ​​to xyY values. Specifically, the electronic device (100) can normalize the RGB values ​​and apply gamma inverse correction. The electronic device (100) can calculate X, Y, and Z values ​​using a conversion matrix on the RGB values ​​to which gamma inverse correction has been applied. The electronic device (100) can calculate a first xyY value corresponding to the first RGB value using a formula that converts the X, Y, and Z values ​​to xyY values. The x and y values ​​included in the first xyY value represent the first color coordinates, and the Y value represents the brightness value.

[0075] Additionally, the electronic device (100) can obtain second color coordinates corresponding to the second color data by converting the second color data obtained in step 330 (S330) from RGB values ​​to xyY values.

[0076] At this time, each of the second color data may correspond to each of the changed screen setting information. For example, when the screen of the second display device (220) is set to the first screen setting information, the color data obtained by photographing the screen of the second display device (220) may be referred to as the second-1 color data. Additionally, after the screen of the second display device (220) is changed from the first screen setting information to the second screen setting information, the color data obtained by photographing the screen of the second display device (220) may be referred to as the second-2 color data. However, it is not limited thereto.

[0077] The electronic device (100) can obtain second color coordinates corresponding to a plurality of screen information by converting second color data, including second-1 color data and second-2 color data, from RGB values ​​to xyY values. For example, the second color coordinates may include a second-1 color coordinate corresponding to first screen setting information and a second-2 color coordinate corresponding to second screen setting information.

[0078] The electronic device (100) can identify the color coordinate closest to the first color coordinate among the second color coordinates. For example, in a color coordinate system, it can identify the second color coordinate corresponding to the second point closest to the first point represented by the first color coordinate among the second points represented by the second color coordinates.

[0079] Additionally, the electronic device (100) can identify screen setting information corresponding to the identified second color coordinate. For example, if the identified color coordinate is the second-2 color coordinate, it can identify the second screen setting information corresponding thereto.

[0080] The electronic device (100) can set the screen of the second display device (210) to the identified screen information (S350).

[0081] For example, the electronic device (100) can set the screen of the second display device (220) to the identified second screen setting information using DDC / CI communication.

[0082] FIG. 4 is a diagram illustrating a method for obtaining color data of a screen of a first display device using an external device according to one embodiment.

[0083] An electronic device (100) according to one embodiment can be connected to a first display device (210) through an input / output interface and can perform DDC / CI communication.

[0084] In an electronic device (100) according to one embodiment, a program (application) for performing screen calibration may be installed. For example, the electronic device (100) may control the first display device (210) to display an icon representing the program for performing screen calibration. When the electronic device (100) receives user input selecting the icon, it may execute the program for screen calibration.

[0085] When a program for screen calibration is executed, the electronic device (100) can set a reference display device and a target display device based on user input.

[0086] For example, referring to FIG. 4, when the first display device (210) is set as a reference display device, the number '1' may be displayed on the screen of the first display device (210). However, this is not limited thereto, and the fact that the first display device (210) is a reference display device may be indicated in various ways.

[0087] The electronic device (100) can transmit reference pattern information to the first display device (210) via DDC / CI communication. The first display device (210) can display a reference pattern based on the reference pattern information received from the electronic device (100). At this time, the reference pattern may be a white pattern. However, it is not limited thereto.

[0088] An electronic device (100) according to one embodiment can control the first display device (210) so that an object guiding a shooting area is displayed on the screen of the first display device (210). For example, the electronic device (100) can control the first display device (210) via DDC / CI communication so that a guide box (410) having a first color is displayed on the screen of the first display device (210). However, it is not limited thereto.

[0089] Additionally, a program for screen calibration may be installed in an external device (300) according to one embodiment. Based on user input, the program for screen calibration installed in the external device (30) may be executed. When the program for screen calibration is executed, the external device (300) may establish communication with the electronic device (100) based on user input and capture the screens of the first display device (210) and the second display device (220).

[0090] As illustrated in FIG. 4, when an external device (300) is positioned in a guide box (410) displayed on the screen of the first display device (210), the screen of the first display device (210) can be automatically captured by the camera of the external device (300). Alternatively, the external device (300) can capture the screen of the first display device (210) based on user input. However, it is not limited thereto.

[0091] The external device (300) can obtain first color data by capturing the screen of the first display device (210). The external device (300) can transmit the first color data to the electronic device (100). At this time, the first color data transmitted to the electronic device (100) may include RGB values ​​and may be raw data before image processing is performed in the camera.

[0092] When the electronic device (100) finishes capturing the screen of the first display device (210) by the external device (300) and the first color data is acquired, it can change the attributes of the object guiding the shooting area that was displayed on the screen of the first display device (210). For example, the electronic device (100) can control the first display device (210) to display the guide box (410) in the second color by changing the color of the guide box (410) that was displayed on the screen of the first display device (210) from the first color to the second color.

[0093] Accordingly, the user can easily recognize that the process of acquiring the first color data for the screen of the first display device (210) is completed.

[0094] FIG. 5 is a diagram illustrating a method for obtaining color data of a screen of a second display device using an external device according to one embodiment.

[0095] An electronic device (100) according to one embodiment can be connected to a second display device (220) through an input / output interface and can perform DDC / CI communication.

[0096] The second display device (220) may be a target display device that is subject to screen calibration to match the same color and brightness as the screen of the reference display device.

[0097] When the second display device (200) is set as a target display device, the number '2' may be displayed on the screen of the second display device (220). However, this is not limited thereto, and the fact that the second display device (220) is a target display device may be indicated in various ways.

[0098] The electronic device (100) can transmit pattern information identical to the reference pattern transmitted to the first display device (210) to the second display device (220) via DDC / CI communication. The second display device (220) can display the reference pattern based on the reference pattern information received from the electronic device (100). At this time, the reference pattern may be a white pattern. However, it is not limited thereto.

[0099] An electronic device (100) according to one embodiment can control the second display device (220) so that an object guiding a shooting area is displayed on the screen of the second display device (220). For example, the electronic device (100) can control the second display device (220) via DDC / CI communication so that a guide box (510) of a first color is displayed on the screen of the second display device (220). However, it is not limited thereto.

[0100] As illustrated in FIG. 5, when an external device (300) is positioned in a guide box (510) displayed on the screen of the second display device (220), the screen of the second display device (220) can be automatically captured by the camera of the external device (300). Alternatively, the external device (300) can capture the screen of the second display device (220) based on user input. However, it is not limited thereto.

[0101] An electronic device (100) according to one embodiment can change the screen setting information of the second display device (220) while the screen of the second display device (220) is being captured by an external device (300).

[0102] According to one embodiment, the second display device (220) may include a screen menu for setting information about the screen. The screen menu may include menus for changing picture mode, brightness, contrast, color temperature, color space, etc.

[0103] For example, the electronic device (100) can control the second display device (220) so that the color temperature menu setting among the screen menus of the second display device (220) is changed. The color temperature of the second display device (220) can be set to any one of the first to fourth modes (e.g., cool, standard, warm 1, warm 2).

[0127] An electronic device (100) according to one embodiment can identify screen setting information based on the second color data that is most similar to the first color data among the second color data.

[0128] For example, the electronic device (100) can identify second-2 color data corresponding to a third point (630) closest to a first point (610) corresponding to the first color data. Additionally, the electronic device (100) can identify screen setting information corresponding to the second-2 color data (e.g., the color temperature is set to a second mode ("Standard")).

[0129] The electronic device (100) can control the second display device (220) so that the screen of the second display device (220) is set to the identified screen setting information.

[0130] Alternatively, the electronic device (100) may set the screen of the second display device (220) to identified screen setting information based on user input. This will be explained with reference to FIG. 7.

[0135] When the electronic device (100) receives user input from the external device (300) or the second display device (220) to set the screen of the second display device (220) to identified screen setting information or a recommended mode selected by the user, the electronic device (100) can set the screen of the second display device (220) to screen setting information corresponding to the identified screen setting information or the recommended mode selected by the user.
