[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present invention provides a brightness parameter debugging method, which is applied to a debugging device, such as Figure 1 As shown, the method includes:

[0041] S11. Based on the brightness parameter values ​​of the camera modules of the multiple terminals that have completed debugging, for each brightness parameter, respectively construct a brightness parameter conversion relationship between the main camera module and other camera modules, wherein the multiple terminals use the same chip platform.

[0042] S12: Debug the brightness parameters of the main camera module of the terminal to be debugged to obtain various brightness parameter values ​​of the main camera module, wherein the terminal to be debugged and the multiple terminals that have completed debugging use the same chip platform.

[0043] S13: for each brightness parameter, determine the brightness parameter values ​​of other camera modules according to the brightness parameter value of the main camera module and the brightness parameter conversion relationship between the main camera module and other camera modules.

[0044] The brightness parameter debugging method provided by the embodiment of the present invention can construct a brightness parameter conversion relationship between the main camera module and other camera modules for each brightness parameter based on the brightness parameter values ​​of each camera module of multiple terminals under the same chip platform that have completed debugging. When the brightness parameters of other terminals under the same chip platform are subsequently debugged, it is only necessary to debug the brightness parameters of the main camera module, and the brightness parameters of other camera modules can be obtained according to the brightness parameter conversion relationship, thereby saving the time and labor costs consumed in brightness parameter debugging.

[0045] The brightness parameter debugging method of the present invention is described in detail below with reference to specific embodiments.

[0046] The brightness parameter debugging method provided in this embodiment includes the following steps:

[0047] S21. Based on the brightness parameter values ​​of the camera modules of the plurality of terminals that have completed debugging, for each brightness parameter, respectively construct a brightness parameter conversion relationship between the main camera module and other camera modules.

[0048] The terminal is an electronic device such as a mobile phone or a tablet with multiple camera modules, and the multiple camera modules include a front camera module, a wide-angle module, a telephoto module, and a main camera module, but are not limited thereto. The multiple terminals use the same chip platform to ensure that the software and hardware links of each terminal are consistent.

[0049] The brightness parameters include multiple parameters under the automatic exposure module, the Gamma module and the tone mapping module, and each module has multiple brightness parameters.

[0050] Specifically, for each brightness parameter, the credibility of the brightness parameter of the main camera module is calculated according to the total number of camera modules of multiple terminals that have completed debugging and the brightness parameter value of each camera module. The specific calculation is performed as follows:

[0051] If the total number of camera modules of multiple terminals that have completed debugging is n, for a certain brightness parameter, the brightness parameter value of a camera module is X i , the brightness parameter value of the corresponding main camera module is Y, and the average brightness parameter value of all camera modules is μ, then the credibility of the brightness parameter of the main camera module is c v for:

[0052]

[0053] If the credibility c v If the brightness parameter is less than a preset threshold, the brightness parameter is a reusable parameter, and the brightness parameter values ​​of other camera modules are equal to the brightness parameter value of the main camera module;

[0054] If the credibility c v If the brightness parameter is not less than a preset threshold, the brightness parameter is a specific parameter. For other camera modules, the conversion curve between the brightness parameters of the main camera module and other camera modules is fitted according to the brightness parameter values ​​of other camera modules.

[0055] For the front camera module, the size of the specific parameter is related to the presence of the human face; for the wide-angle module and telephoto module, the size of the specific parameter is related to the difference in the module's field of view angle.

[0056] For example, there are two terminals 1 and 2 that have completed brightness parameter debugging, each with four camera modules: front camera module, wide-angle module, telephoto module and main camera module, then the total number of camera modules of the two terminals is n = 8. For a certain brightness parameter, the brightness parameter values ​​of the front camera module, wide-angle module, telephoto module and main camera module of terminal 1 are X1, X2, X3 and X4 respectively, and the brightness parameter value of the main camera module is Y1; the brightness parameter values ​​of the front camera module, wide-angle module, telephoto module and main camera module of terminal 2 are X5, X6, X7 and X8 respectively, and the brightness parameter value of the main camera module is Y2; the average value μ of the brightness parameter values ​​of all camera modules is (X1+X2+X3+X4+X5+X6+X7+X8) / 8, then the credibility c of the brightness parameter of the main camera module is v for:

[0057]

[0058] If the credibility c v If the brightness parameter is less than a preset threshold, the brightness parameter is a reusable parameter, and the brightness parameter values ​​of other camera modules are equal to the brightness parameter value of the main camera module;

[0059] If the credibility c v If the value is not less than the preset threshold, the brightness parameter is a specific parameter. For the front camera module, the conversion curve between the brightness parameters of the front camera module and the main camera module is obtained by fitting according to the brightness parameter value X1 of the front camera module of terminal 1 and the brightness parameter value Y1 of the main camera module, and the brightness parameter value X5 of the front camera module of terminal 2 and the brightness parameter value Y2 of the main camera module. In a similar manner, the conversion curve between the brightness parameters of the wide-angle module and the main camera module, and the conversion curve between the brightness parameters of the telephoto module and the main camera module can be obtained respectively.

[0060] S22: Debug the brightness parameters of the main camera module of the terminal to be debugged, and obtain the brightness parameter values ​​of the main camera module.

[0061] The terminal to be debugged currently uses the same chip platform as the multiple terminals that have completed debugging, so as to ensure the consistency of the software and hardware links.

[0062] Specifically, firstly, each initial brightness parameter value of the main camera module automatically generated by the debugging tool for the terminal to be debugged is obtained.

[0063] Use the debugging tool to automatically generate a set of default initial brightness parameter values ​​of the main camera module for the terminal to be debugged, including multiple brightness parameter values ​​under the automatic exposure module, gamma module, and tone mapping module.

[0064] Then, based on the initial brightness parameter values ​​of the main camera module, the brightness parameters of the main camera module are finely adjusted under full scene coverage to obtain a set of optimal brightness parameter values ​​of the main camera module.

[0065] When debugging the brightness parameters of the main camera module, the shooting scenes must cover indoors, outdoors, restaurants, shopping malls, night scenes, etc.; the color temperature of the shooting scenes must cover low, medium, and high color temperatures; the brightness must cover low, medium, and high brightness, as well as front light, back light, and side light; the shooting distance must cover macro, close range, medium range, and long range; the shooting objects must cover people, sky, buildings, grass, plants, flowers, concrete floors, food, objects with rich colors / textures, etc.

[0066] S23: for each brightness parameter, determine the brightness parameter values ​​of other camera modules according to the brightness parameter value of the main camera module and the brightness parameter conversion relationship between the main camera module and other camera modules.

[0067] When debugging the brightness parameters of other camera modules, first calibrate the brightness modules of other camera modules to ensure that the brightness values ​​output by other camera modules and the main camera module are the same in the same scene. Then input the information of the current camera module, including the module position information, the module field of view angle, etc., to determine which camera module to be debugged.

[0068] Then, when the brightness parameter of the main camera module is a reusable parameter, the brightness parameter value of the main camera module is used as the brightness parameter value of other camera modules; when the brightness parameter of the main camera module is a specific parameter, the brightness parameter value of the main camera module is converted according to the conversion curve between the brightness parameters of the main camera module and other camera modules to obtain the brightness parameter values ​​of other camera modules. The brightness parameter thus obtained can ensure that the brightness effect of each camera module to be debugged can meet the test standards of most terminals.

[0069] S24: For other camera modules, based on the determined brightness parameter values ​​of other camera modules, the brightness parameters of the automatic exposure module and the brightness parameters of the tone mapping module in the backlight scene are debugged to optimize the current brightness effect.

[0070] Since there are differences between the main camera module and other camera modules, through analyzing the brightness parameters of the debugged terminals and the corresponding picture effects, it is found that the effect differences caused by the differences in camera modules mainly affect the brightness effects of high dynamic scenes and the contrast effects of some scenes. Therefore, the current brightness parameters of other camera modules to be debugged can be optimized. Specifically, based on the determined brightness parameter values ​​of other camera modules, the brightness parameters of the automatic exposure module in the backlight scene can be debugged in a focused manner to solve the effect differences caused by the differences in camera modules. In addition, the brightness parameters of the tone mapping module can be debugged to further optimize the image contrast.
