[0002] Lens shading is a characteristic of the lens, which is caused by the uneven optical refraction of the lens, resulting in shadows around the lens. Lens shading correction (LSC) is used to solve the problem of lens shading.

[0003] Lens shading correction data (referred to as LSC data) is data used to compensate for the vignetting of the camera module. Lens shading correction data is generally burned into the camera module before it leaves the factory. If the LSC data burned into the module is abnormal, the module will have very obvious image defects such as color cast and uneven brightness, and it will basically be unable to be used normally. Therefore, before the module leaves the factory, the LSC data burned into the module needs to be verified.

[0004] The LSC data detection device that verifies the LSC data burned in the module itself needs to ensure the accuracy of the verification. However, in the related technology, a physical module with multiple LSC data burning errors is produced to verify whether the detection results of the detection device are accurate, which leads to high verification costs.

[0042] The embodiment of the present application solves the technical problem of high cost in verifying the detection capability of detection equipment to detect LSC data in the prior art by providing a detection function verification method.

[0043] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0044] A detection function verification method is applied to an LSC data detection device, the method comprising: obtaining standard LSC data and sample LSC data according to a target camera module; detecting the standard LSC data and the sample LSC data respectively by an LSC data detection device to obtain a detection result; and determining whether the detection function of the LSC data detection device is normal according to the detection result.

[0045] This embodiment can obtain standard LSC data with correct sequence and sample LSC data with incorrect sequence based on the LSC data in the target camera module, and can simulate obtaining standard LSC data with correct sequence and sample LSC data with incorrect sequence under the premise of avoiding making erroneous burning software and non-conforming modules; use LSC data detection equipment to detect the obtained standard LSC data and sample LSC data to obtain detection results, and according to the detection results, it can be determined whether the detection function of the LSC data detection equipment is normal, thereby saving the verification cost of the LSC data detection equipment.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0048] The LSC data corresponding to different types of camera modules are not necessarily the same, but the LSC data corresponding to the same type of camera modules are the same. In this embodiment, the device for detecting whether the LSC data in the camera module is burned incorrectly is recorded as the LSC data detection device. The detection result of the LSC data detection device determines whether the performance of the detected camera module is good or not. Therefore, the detection accuracy of the LSC data detection device is extremely important.

[0049] In the related art, in order to verify the detection accuracy of the LSC data detection device, it is necessary to prepare a wrong burning software, and make multiple non-conforming modules with LSC data burning errors based on this wrong burning software, and use the LSC data detection device to detect the non-conforming modules and the good modules respectively to verify the detection accuracy of the LSC data detection device. However, the LSC data corresponding to different types of camera modules are inconsistent, so for each type of camera module, it is necessary to prepare corresponding burning software and non-conforming modules with burning errors, and non-conforming modules can only be scrapped, resulting in a particularly high verification cost. In addition, the burning software corresponding to each type of camera module, the non-conforming modules with burning errors, and the good modules with correct burning can only verify whether the detection effect of the LSC data detection device for this type of camera module is accurate, and cannot be transplanted to other types of module verification tests. It can be seen that its portability is poor, and the verification cost is further increased. At the same time, it takes a lot of time to make wrong burning software and non-conforming modules with burning errors, resulting in a long verification cycle, which in turn leads to a long development cycle.

[0050] In order to solve the above problems, this embodiment provides Figure 1 A detection function verification method is shown, the method comprising:

[0051] Step S11, obtaining standard LSC data and sample LSC data according to the target camera module.

[0052] The LSC data detection device obtains standard LSC data and sample LSC data according to the target camera module. For the target camera module, the LSC data itself is composed of multiple color channels in a unique arrangement order. If the order of the color channels is wrong, the corresponding LSC data is wrong. Only when the order of each color channel is consistent with the only correct arrangement order, the corresponding LSC data can be considered as standard LSC data. If the order of each color channel is inconsistent with the only correct arrangement order, the corresponding LSC data is sample LSC data. That is, the purpose of step S11 is to obtain standard LSC data with correct order and sample LSC data with incorrect order from the target camera module.

[0053] The camera module with correct LSC data burned is called a good module, and the camera module with incorrect LSC data burned is called a non-good module. In this embodiment, the correct LSC data read out from the good module is recorded as standard LSC data. That is, the standard LSC data can be directly read and obtained from the existing good module. For the same type of module, the order of each color channel of the LSC data in its target camera module is unique. For this type of module, other LSC data inconsistent with the unique order are all wrong LSC data. In this embodiment, the wrong LSC data is recorded as sample LSC data.

[0054] According to the target camera module, the standard LSC data is obtained, specifically including: reading the data according to the original order of each color channel storing the LSC data in the target camera module to obtain the standard LSC data. Among them, for the same type of camera module, the original order of each color channel in the corresponding target LSC data is unique, and the standard LSC data can be obtained by reading according to the original order of each color channel storing the LSC data in the target camera module.

[0055] For example, the target LSC data burned into the A-type good module is RGrGbB (where R, Gr, Gb, and B are color channels), and the corresponding original order is [1] R, [2] Gr, [3] Gb, and [4] B. The standard LSC data obtained from the A-type good module is RGrGbB.

[0056] According to the target camera module, sample LSC data is obtained, specifically including: reading data according to the expected error order of each color channel storing LSC data in the target camera module to obtain sample LSC data. Wherein, the order of each color channel in the sample LSC data is inconsistent with the order of each color channel in the target LSC data (or in the standard LSC data), and the sample LSC data can be obtained by reading according to the expected error order of each color channel storing LSC data in the target camera module (the expected error order is inconsistent with the original order).

[0057] For example, if the target LSC data programmed in the A-type good module is RGrGbB, then the corresponding original order (i.e., the only correct order) is [1] R, [2] Gr, [3] Gb, [4] B. By reading according to the expected error order (the expected error order is inconsistent with the original order) of the target LSC data programmed in the A-type good module, the sample LSC data can be obtained. Since the error order is read, the obtained sample LSC data can be multiple, for example, the sample LSC data can be GrRGbB, GbRGrB, BRGrGb, RGrBGb, etc.

[0058] For the LSC data detection device, the LSC data detection device reads the LSC data from the module to be detected into the memory, and then detects the read LSC data to determine whether the corresponding module is burned incorrectly. In the process of reading the LSC data detection device, this embodiment sets two reading modes, one mode is the normal reading mode, that is, the data is read according to the original order of each color channel storing the LSC data in the target camera module to obtain standard LSC data; the other mode is the error reading mode, that is, the data is read according to the expected error order of each color channel storing the LSC data in the target camera module to obtain sample LSC data. In other words, this embodiment transforms the function of the LSC data detection device itself to read LSC data, so that the LSC data detection device can obtain standard LSC data and sample LSC data respectively in two modes, and then can directly realize self-detection to determine whether the detection results of the LSC data detection device itself for various LSC data are accurate.

[0059] First, this embodiment can avoid producing good modules with incorrect burning software and LSC data burning errors, thus saving verification costs; secondly, this method can be used to verify any type of module, thus improving portability and further reducing verification costs; then, it saves time in producing modules with incorrect burning software and LSC data burning errors, shortens the verification cycle, thus shortening the R&D cycle, and improving verification efficiency; finally, the LSC data detection device can be self-checked regularly to ensure the accuracy of the detection results of the LSC data detection device.

[0060] Step S12, respectively testing the standard LSC data and the sample LSC data by using an LSC data testing device to obtain a testing result.

[0061] The LSC data detection device detects the standard LSC data and the sample LSC data respectively to obtain the detection results. After obtaining the standard LSC data with the correct sequence and the sample LSC data with the wrong sequence, the standard LSC data and the sample LSC data can be input into the LSC data detection device for detection to obtain the detection results.

[0062] Step S13, determining whether the detection function of the LSC data detection device is normal according to the detection result.

[0063] The LSC data detection device can determine whether the LSC data detection device is accurate in detecting the LSC data based on the detection result.

[0064] Specifically, step S12 and step S13 can be decomposed into the following steps (eg Figure 2 shown):

[0065] Step S21, testing the standard LSC data to obtain a standard test result;

[0066] Step S22, testing the sample LSC data to obtain the sample testing result.

[0067] Step S23, determining whether the standard test result and the sample test result meet the verification condition, wherein the verification condition includes that the standard test result is correct and the sample test result is wrong;

[0068] Step S24: If yes, it is determined that the detection function of the LSC data detection device is normal;

[0069] Step S25: If not, it is determined that the detection function of the LSC data detection device is abnormal.

[0070] For standard LSC data, the order of the corresponding color channels is consistent with the target camera module, so the detection result for the standard LSC data matching should be "correct". If the detection result obtained by the LSC data detection device when detecting standard LSC data is "wrong", then the detection result of the LSC data detection device is inaccurate, which means that there is a problem with the accuracy of the LSC data detection of the LSC data detection device, which also determines that the detection function of the LSC data detection device is abnormal.

[0071] For the sample LSC data, the order of the corresponding color channels is inconsistent with the target camera module, so the detection result for the sample LSC data matching should be "wrong". If the detection result obtained by the LSC data detection device when detecting the sample LSC data is "correct", then the detection result of the LSC data detection device is inaccurate, which means that there is a problem with the accuracy of the LSC data detection of the LSC data detection device, which also determines that the detection function of the LSC data detection device is abnormal.

[0072] Regardless of whether it is standard LSC data or sample LSC data, as long as the LSC data detection device gives a detection result that does not match one of the LSC data, it means that there is a problem with the accuracy of the LSC data detection of the LSC data detection device, and it is determined that the detection function of the LSC data detection device is abnormal. Conversely, if the LSC data detection device gives matching detection results for both standard LSC data and sample LSC data, it means that there is no problem with the accuracy of the LSC data detection of the LSC data detection device, and it is determined that the detection function of the LSC data detection device is normal.

[0073] During the actual production verification process, steps S11 to S13 are executed respectively for a preset number of types of modules (for example, 3 groups), and the verification results are all verified. Then, it can be determined that there is no problem with the accuracy of the LSC data detection equipment, and the LSC data detection equipment can be put into normal LSC data burning verification production.

[0074] Furthermore, for modules of the same type, the corresponding standard LSC data is unique, but the number of corresponding sample LSC data is not unique. Therefore, when the number of sample LSC data is multiple, the principle of LSC data detection capability verification is similar. Only when the LSC data detection device gives matching detection results for both the unique standard LSC data and multiple sample LSC data, can it be considered that the detection results of the LSC data detection device for the LSC data are accurate, and the LSC data detection device can be put into normal LSC data burning verification production.

[0075] When the number of sample LSC data is multiple, the specific verification process is as follows:

[0076] The standard LSC data is tested to obtain a standard test result; the multiple sample LSC data are tested respectively to obtain multiple sample test results. It is determined whether the standard test result and the multiple sample test results meet the verification condition, wherein the verification condition includes that the standard test result is correct and the multiple sample test results are all wrong; if so, it is determined that the detection function of the LSC data detection device is normal; if not, it is determined that the detection function of the LSC data detection device is abnormal.

[0077] Table 1

[0078]

[0079] For example, the target LSC data burned in the A-type good module is RGrGbB, and the standard LSC data and sample LSC data obtained according to the target LSC data burned in the A-type good module are shown in Table 1. When the test results obtained by the LSC data detection device after testing the standard LSC data and each sample LSC data are as shown in Table 1, the detection capability of the LSC data detection device for LSC data is verified, the test results are accurate, and the detection function of the LSC data detection device is normal. If the test results obtained by the LSC data detection device after testing the standard LSC data and each sample LSC data are different from the test results shown in Table 1, the detection capability of the LSC data detection device for LSC data is not verified, the test results are inaccurate, and the detection function of the LSC data detection device is abnormal.

[0080] To summarize, this embodiment can obtain standard LSC data with correct sequence and sample LSC data with incorrect sequence according to the LSC data in the target camera module, and can simulate obtaining standard LSC data with correct sequence and sample LSC data with incorrect sequence under the premise of avoiding making erroneous burning software and non-conforming modules; use LSC data detection equipment to detect the obtained standard LSC data and sample LSC data to obtain detection results, and according to the detection results, it can be determined whether the detection function of the LSC data detection equipment is normal, thereby saving the verification cost of the detection equipment.
