Description

Technical Field

[0001] This invention provides a display parameter setting method and a computer device thereof, particularly a display parameter setting method and computer device that can automatically transmit parameter setting values ​​between different display devices. Background Technology

[0002] Due to hardware differences between various display devices, even with the same display parameter settings, significant color variations can still occur, making it difficult to switch display parameter settings between different devices. Furthermore, traditional display devices use on-screen menus (OSD) to adjust display parameter settings, a time-consuming and error-prone process. Traditional display parameter calibration methods use colorimeters and dedicated software, which, while providing accurate color display, incur additional hardware / software costs and are relatively complex to implement. Summary of the Invention

[0003] This invention provides a display parameter setting method and computer device that can automatically transmit parameter setting values ​​between different display devices to solve the above-mentioned problems.

[0004] One embodiment of the present invention discloses a display parameter setting method applied to a computer device electrically connected to a first display device and a second display device. The display parameter setting method includes the computer device's processing unit obtaining parameter compensation values, and the processing unit applying the parameter compensation values ​​to the second display device so that the second display device can present a display effect identical to that of the first display device.

[0005] Preferably, the parameter compensation value is obtained by converting the first reference parameter and the first current parameter of the first display device.

[0006] Preferably, the first reference parameter is the original setting of the first display device before any customization adjustment, while the first current parameter is the customized setting obtained by the first display device according to the control command.

[0007] Preferably, the method further includes the following: the processing unit reads the first reference parameter and the first current parameter; and the processing unit calculates the difference between the first reference parameter and the first current parameter as a parameter compensation value.

[0008] Preferably, the method further includes: the processor reading a second reference parameter of the second display device; and the processor calculating the sum of the parameter compensation value and the second reference parameter as a second current parameter of the second display device.

[0009] Preferably, the first display device has multiple color correlation parameters, and each color correlation parameter can be calculated to have its own compensation value. The processing unit establishes the multiple compensation values ​​of the multiple color correlation parameters into a display parameter setting file, which is then transmitted to the second display device.

[0010] The present invention also discloses a computer device comprising a first display device, a second display device, and a processing unit. The processing unit is electrically connected to the first display device and the second display device. The first display device has a first reference parameter and a first current parameter. The processing unit obtains a parameter compensation value associated with the first display device and applies the parameter compensation value to the second display device so that the second display device can present a display effect identical to that of the first display device. The parameter compensation value is obtained by converting the first reference parameter and the first current parameter.

[0011] Preferably, the processor reads the first reference parameter and the first current parameter, and calculates the difference between the first reference parameter and the first current parameter as a parameter compensation value.

[0012] Preferably, the processor reads the second reference parameter of the second display device, and then calculates the sum of the parameter compensation value and the second reference parameter as the second current parameter of the second display device.

[0013] Preferably, the first reference parameter is the original setting of the first display device before any customization adjustment, while the first current parameter is the customized setting obtained by the first display device according to the control command.

[0014] Preferably, the first display device has multiple color correlation parameters, and each color correlation parameter can be calculated to have its own compensation value. The processing unit establishes the multiple compensation values ​​of the multiple color correlation parameters into a display parameter setting file, which is then transmitted to the second display device.

[0015] Compared with existing technologies, the display parameter setting method and computer device of the present invention can directly read the original settings of the display device, or can use a specific component to read the original settings of the display device and connect to the specific component to receive the read original settings, and then obtain parameter compensation values ​​based on the difference between the original settings (reference parameters) and the customized settings (current parameters) of the display device. The display parameter setting file formed by multiple parameter compensation values ​​can be transferred and applied between different display devices. In this way, even if the first display device and the second display device have different models or batch numbers, the display parameter setting method can adjust the color correlation parameters between the two display devices to be consistent by transferring the display parameter setting file.

[0020] To provide a further understanding of the purpose, structure, features and functions of the present invention, detailed descriptions are provided below with reference to embodiments.

[0021] Please see Figure 1 and Figure 2 , Figure 1 This is a functional block diagram of the computer device 10 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the appearance of a computer device 10 according to an embodiment of the present invention. The computer device 10 may include a first display device 12, a second display device 14, and a processing unit 16. Generally, the processing unit 16 is located inside the computer host; the first display device 12 and the second display device 14 are monitors independent of the computer host and electrically connected to the computer host via wired or wireless means, but practical applications are not limited to this. The computer host is electrically connected to an input interface, such as a mouse or keyboard. The user can input control commands using the input interface, and the processing unit 16 parses the control commands to determine how to adjust the first display device 12 and the second display device 14.

[0022] Display devices undergo a certain degree of color calibration before leaving the factory to achieve consistent color performance. However, due to hardware differences between different display devices, the calibrated display parameters will vary from device to device. In this invention, the reference parameters refer to the original settings of the display device before any customization adjustments, that is, the display parameters calibrated before leaving the factory; the current parameters are the customized settings obtained by the display device according to control commands, that is, the results of adjustments made by the user according to their preferences.

[0023] For example, the first display device 12 may be an old monitor, and the second display device 14 may be a new monitor. The user may wish to replace the first display device 12 with the second display device 14 because the first display device 12 is damaged or does not meet their needs. The user can use the computer's processor 16 to execute the display parameter setting method of this invention, so that the second display device 14 can present the same display effect as the first display device 12. The aforementioned display parameters may be color parameters, brightness parameters, color temperature parameters, gain parameters, or any other parameters applied to the display.

[0024] Please see Figure 3 and Figure 4 , Figure 3 This is a flowchart of the display parameter setting method according to an embodiment of the present invention. Figure 4 This is a functional block diagram of the display parameter setting method according to an embodiment of the present invention. Figure 3 and Figure 4 The aforementioned display parameter setting method can be applied to Figure 1 and Figure 2 The computer device 10 shown. First, the display parameter setting method executes steps S100 and S102 to obtain the first reference parameter and the first current parameter of the first display device 12, and calculates the difference between the first reference parameter and the first current parameter as a parameter compensation value. Figure 4 As shown, the symbols A, B, and C of the first reference parameter and the first current parameter represent multiple color-related parameters, such as three of the following: color parameter, brightness parameter, color temperature parameter, and gain parameter; however, the types and number of parameters are not limited to those described in this embodiment and depend on the design requirements.

[0025] Furthermore, both the first display device 12 and the second display device 14 have multiple color-related parameters. Each color-related parameter can have its own calculated parameter compensation value. That is, the color parameter can have a color-related parameter compensation value between the first reference parameter and the first current parameter, the brightness parameter can have a brightness-related parameter compensation value between the first reference parameter and the first current parameter, the color temperature parameter can have a color temperature-related parameter compensation value between the first reference parameter and the first current parameter, and the gain parameter can have a gain-related parameter compensation value between the first reference parameter and the first current parameter. In step S102, the parameter compensation value can be a set of all color-related settings, and the majority of the parameter compensation values ​​of the multiple color-related parameters can be stored as a set of display parameter setting files.

[0026] Next, the display parameter setting method executes steps S104, S106, and S108, reads the second reference parameter of the second display device 14, applies the display parameter setting file and its parameter compensation value to the second reference parameter to obtain the second current parameter, and then adjusts the second display device 14 with the second current parameter so that the second display device 14 can present the same display effect as the first display device 12. In step S106, the display parameter setting method can calculate the sum of the parameter compensation value and the second reference parameter as the second current parameter of the second display device 14; however, the parameter compensation value obtained by converting the current parameter and the reference parameter can also be generated by other functions, such as the ratio between the current parameter and the reference parameter, or calculated using a multivariate polynomial equation.

[0027] In this invention, the display parameter setting method can use the Monitor Control Command Set (MCCS) standard, which is based on the Display Data Channel Command Interface (DDC / CI), to obtain the first reference parameter and the first current parameter of the first display device 12, and the second reference parameter and the second current parameter of the second display device 14, thereby calculating the parameter compensation value. The display parameter setting file and its parameter compensation value are then transferred between the first display device 12 and the second display device 14 for application. Alternatively, the display parameter setting method may also utilize the firmware of the first display device 12 and the second display device 14 to directly obtain and apply the display parameter setting file and its parameter compensation value. The method of obtaining and transferring the parameter compensation value is not limited to the aforementioned embodiments, but depends on the configuration function of the computer device 10. Other possible embodiments will not be described separately here.

[0028] In summary, the display parameter setting method and computer device of the present invention can directly read the original settings of the display device, or can use a specific component to read the original settings of the display device and connect to the specific component to receive the read original settings, and then obtain parameter compensation values ​​based on the difference between the original settings (reference parameters) and the customized settings (current parameters) of the display device. A display parameter setting file formed by multiple parameter compensation values ​​can be transferred and applied between different display devices. In this way, even if the first display device and the second display device have different models or batch numbers, the display parameter setting method can adjust the color correlation parameters between the two display devices to be consistent by transferring the display parameter setting file.

[0029] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
