[0055] Figure 2 A signaling diagram of a color calibration method is illustrated according to an embodiment of the present invention. The color calibration system 10 may perform Figure 2 the steps to complete the color calibration of the display device 300.

[0056] In step S201, the server 100 may register the image capturing device 200 to allocate corresponding channel information for future data transmission of the image capturing device 200. Specifically, the image capturing device 200 may transmit a registration message to the server 100. The server 100 may allocate channel resources for the image capturing device 200 according to the registration message. The channel resources may include but are not limited to time domain resources (e.g., time slots) or frequency domain resources (e.g., bandwidth) required for data transmission in a wireless network.

[0057] In step S202, the display device 300 may output pairing information. Specifically, the display device 300 may generate pairing information according to the identification code of the display device 300 (e.g., device identification code), and output the pairing information through the transceiver 330 or the input / output device 340. For example, the processor 310 may output the pairing information to a device (e.g., the image capturing device 200) communicatively connected to the display device 300 through the transceiver 330. As another example, the processor 310 may display an image containing the pairing information through the input / output device 340. The pairing information is, for example, displayed in the form of a two-dimensional barcode. In one embodiment, the calibration software 321 may display a calibration image containing the pairing information through the input / output device 340.

[0058] In step S203, the image capturing device 200 may obtain the pairing information from the display device 300, and obtain the identification code corresponding to the display device 300 from the pairing information. In addition, the image capturing device 200 may further obtain a timestamp for synchronization from the display device 300. In one embodiment, the processor 210 of the image capturing device 200 may capture the pairing information in the image displayed by the input / output device 240 of the display device 300 through the input / output device 240. In one embodiment, the processor 210 may receive the pairing information output by the transceiver 230 of the display device 300 through the transceiver 230.

[0059] In step S204, the processor 210 of the image capturing device 200 may upload the identification code to the server 100 through the transceiver 230. In addition, the processor 210 may further upload the timestamp for synchronization to the server 100.

[0060] In step S205, the processor 110 of the server 100 may generate an acknowledgment code corresponding to the identification code according to the identification code and / or the timestamp, and may transmit the acknowledgment code to the image capturing device 200 through the transceiver 130. The image capturing device 200 may output the acknowledgment code through the input / output device 240 for the user's reference.

[0061] In step S206, after the user obtains the confirmation code output by the image capturing device 200, the user can input the confirmation code to the display device 300 through the input / output device 340 of the display device 300. The display device 300 can upload the confirmation code to the server 100 through the transceiver 330.

[0062] In step S207, the server 100 can register the display device 300 according to the confirmation code uploaded by the display device 300 and generate permission management information. The permission management information may include, for example, the valid upload time of the data. That is to say, the image capturing device 200 or the display device 300 can be restricted to complete color calibration within the time range specified by the permission management information. After step S207 ends, the registration procedures of both the image capturing device 200 and the display device 300 are successfully completed. The color calibration system 10 can start executing the color calibration process S3.

[0063] In step S208, the processor 210 of the image capturing device 200 can measure the calibration image displayed on the input / output device 340 of the display device 300 through the input / output device 240, so as to obtain optical characteristic information. The optical characteristic information may include but is not limited to brightness, contrast, color balance, RGB gain, color temperature, Gamma value, resolution, or refresh rate.

[0064] In one embodiment, the image capturing device 200 can periodically measure the optical characteristic information. In one embodiment, the display device 300 can send a request message to the image capturing device 200 through the transceiver 330. The image capturing device 200 can measure the optical characteristic information of the image displayed on the display device 300 according to the request message. That is to say, the image capturing device 200 can measure the optical characteristic information in an on-demand manner.

[0065] In step S209, the image capturing device 200 can upload the optical characteristic information and / or the time stamp for synchronization through the transceiver 230. The server 100 can receive the optical characteristic information from the image capturing device 200 based on the channel resources allocated to the image capturing device 200.

[0066] In step S210, the processor 110 of the server 100 may convert the data format of the optical characteristic information to generate calibration instructions supported by the calibration software 321 of the display device 300. Then, the processor 110 may transmit the calibration instructions to the display device 300 corresponding to the identification code through the transceiver 130. The processor 110 may determine to transmit the calibration instructions to the source of the confirmation code (i.e., the display device 300) based on the confirmation code received in step S206.

[0067] In an embodiment, the processor 110 may generate calibration instructions when the received optical characteristic information matches the permission management information. Specifically, if the timestamp corresponding to the optical characteristic information matches the effective upload time of the permission management information, the processor 110 may determine that the optical characteristic information uploaded by the image capture device 200 is valid. Accordingly, the processor 110 may generate calibration instructions corresponding to the optical characteristic information.

[0068] In step S211, the calibration software 321 of the display device 300 may update the display parameters of the display device 300 according to the calibration instructions, and display and output images through the input / output device 340 according to the updated display parameters. The display parameters may include but are not limited to brightness, contrast, color balance, RGB gain, color temperature, gamma value, resolution, or refresh rate.

[0069] The color calibration system 100 may iteratively execute process S3 until the color calibration of the display device 300 is completed.

[0070] In an embodiment, after the color calibration of the display device 300 is completed, the server 100 may store the current optical characteristic information or display parameters of the display device 300 in the database 121. In the future, when the user desires to recalibrate the display device 300, the display device 300 only needs to access the database 121 through the network to obtain the display parameters, without having to execute process S3 again.

[0071] Figure 3FIG. 0 is a schematic diagram showing color calibration for multiple display devices simultaneously based on multiple image capture devices according to an embodiment of the present invention. The color calibration system 10 can measure the optical characteristic information of the calibration image displayed by the input / output device 340 of the display device 300 through the image capture device 200, and can measure the optical characteristic information of the calibration image displayed by the input / output device 3402 of the display device 3002 through the image capture device 2002. The server 100 can convert the data format of the optical characteristic information uploaded by the image capture device 200 to generate a calibration instruction for calibrating the display device 300, and transmit the calibration instruction to the display device 300. The display device 300 can update the display parameters according to the calibration instruction, and display the output image according to the updated display parameters. On the other hand, the server 100 can convert the data format of the optical characteristic information uploaded by the image capture device 2002 to generate a calibration instruction for calibrating the display device 3002, and transmit the calibration instruction to the display device 3002. The display device 3002 can update the display parameters according to the calibration instruction, and display the output image according to the updated display parameters.

[0072] Figure 4 FIG. 4 is a schematic diagram showing color calibration for N (N is a positive integer greater than 1) display devices simultaneously based on a single image capture device according to an embodiment of the present invention. The image capture device 200 can detect the calibration image displayed by the input / output device 340 of the display device 300 through the input / output device 240 to determine the detection area 410, and can detect the calibration image displayed by the input / output device 3402 of the display device 3002 to determine the detection area 420. After determining the detection area 410 and the detection area 420, the optical characteristic information measured by the image capture device 200 can include the measurement data corresponding to the detection area 410 and the measurement data corresponding to the detection area 420. Therefore, the optical characteristic information can generate multiple calibration instructions for calibrating the display device 300 and the display device 3002 respectively.

[0073] Specifically, after the server 100 receives the optical characteristic data uploaded by the image capture device 200, the server 100 can perform format conversion on the measurement data corresponding to the detection area 410 in the optical characteristic data to generate a calibration instruction for calibrating the display device 300. The display device 300 can receive the calibration instruction to update the display parameters according to the calibration instruction. On the other hand, the server 100 can perform format conversion on the measurement data corresponding to the detection area 420 in the optical characteristic data to generate a calibration instruction for calibrating the display device 3002. The display device 3002 can receive the calibration instruction to update the display parameters according to the calibration instruction.

[0074] Figure 5A flowchart of a color correction method according to an embodiment of the present invention is shown, where the color correction method can be implemented by a color correction system 10 as shown in Figure 1 In step S501, the first correction image displayed by the first display device is measured by the image capture device to obtain optical characteristic information. In step S502, the server receives the optical characteristic information from the image capture device and converts the data format of the optical characteristic information to generate a first correction instruction. In step S503, the first display device receives the first correction instruction from the server, updates the first display parameters of the first display device according to the first correction instruction, and displays a first output image according to the updated first display parameters.

[0075] In summary, the color correction system of the embodiment of the present invention has at least the following advantages: The present invention can be used to perform color correction for a display device that does not support traditional software development kit (SDK) color correction software. After the color correction of the display device is completed, the server can store the display parameters in the cloud for the display device to be corrected to read, so as to reduce the cost of the storage medium in the display device. The display device or the image capture device of the present invention only needs to have a network access function to use the color correction service provided by the server, and there is no need to design a physical input or output interface on the device, so the production cost can be saved (for example: mold opening, connector or waterproof requirements). The present invention can perform color correction for multiple display devices at the same time, increasing the production efficiency of products. The color correction system can provide services to customers in a more flexible business model through application program authorization.
