Detailed Description
In order to better understand the technical solutions, the technical solutions of the embodiments of the present specification are described in detail below with reference to the drawings and specific embodiments, and it should be understood that the specific features of the embodiments and embodiments of the present specification are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification, and the technical features of the embodiments and embodiments of the present specification may be combined with each other without conflict.
An embodiment of the present specification provides a method for burning a camera module, please refer to fig. 1, which is a flowchart of the method for burning a camera module provided in the embodiment of the present specification, and the method includes the following steps:
step S11: acquiring a data set burnt in the first camera module;
step S12: determining the data to be modified in the data set based on preset positioning information of the data to be modified;
step S13: modifying the data to be modified into target data matched with a preset data modification rule based on a preset data modification rule;
step S14: and burning the data set after the data modification into the second camera module.
The method in the embodiment of the specification can be applied to the abnormal burning process of the camera module, wherein the abnormal burning process refers to a process of rewriting all or part of burnt data and burning the rewritten data again. The rewritten data can be burned into the original camera module and can also be burned into other camera modules, and the application is not limited.
In step S11, the first camera module can be selected according to actual needs, and the first camera module is any one of the recorded modules or a specific module. For example, when the data of the camera module of the item a needs to be burned into the camera module of the item B, the first camera module may be the module of the item a, and the second camera module may be the module of the item B.
It should be noted that the data set in the first camera module may be all data burned in the camera module, including various parameter data and verification data of the camera module. For example, the parameter data may include automatic white balance data, luminance data, etc., and the verification data includes Lens Shade Calibration (LSC) data, etc. Of course, the data set in the first camera module may also be part of data burned in the suspected module, such as the auto white balance related data in the first camera module. For convenience of description, in the embodiment of the present specification, a data set is described as an example of all data burned in the first camera module.
In step S12, the data to be modified may be set according to actual needs, and the data to be modified may be all or part of the acquired burning data of the first camera module. The preset positioning information is information for determining a specific position of the data to be modified, and in a specific implementation process, the preset positioning information may be a preset storage address, a preset data type, or other information capable of positioning the data to be modified.
Taking the preset positioning information as the preset data type as an example, the step S12 can be implemented as follows: and determining a target data storage address corresponding to the preset data type based on a preset corresponding relation between the data type and the storage address in the first camera module, and taking the data stored in the target data storage address as the data to be modified.
Specifically, when the first camera module performs data burning, a preset corresponding relationship exists between the data type and the storage address, for example, the first storage address segment is used for storing automatic white balance data, and the second storage address segment is used for storing lens shading calibration data. Therefore, after the preset data type of the data to be modified is determined, the target data storage address of the preset data type can be obtained according to the preset corresponding relationship, and the data to be modified stored in the target data storage address can be further obtained.
In addition, when the preset positioning information is a preset storage address and the data set is all data burned in the first camera module, for example, the preset storage address is 0x 48-0 x50, the data stored in 0x 48-0 x50 can be directly determined from all the acquired data and used as the data to be modified. Of course, the data to be modified may also be determined in other ways, which are not listed here.
In step S13, the preset data modification rule may be set according to actual needs, for example, the preset data modification rule may be a correspondence between the data to be modified and the modified target data, a correspondence between the data to be modified and the data modification range, or a calculation method of the target data. And determining target data corresponding to the data to be modified based on a preset data modification rule, and changing the data to be modified into the target data.
Specifically, if the data to be modified is the auto white balance data, taking the preset data modification rule as the correspondence between the data to be modified and the modified target data as an example, the preset data modification rule may be to modify the auto white balance data to 0x 30. Then, the original automatic white balance data, for example, 0x65, may be determined according to the preset positioning information of the automatic white balance, and then 0x65 may be modified to 0x 30.
In order to implement batch processing of the data to be modified, in the embodiment of the present specification, before performing step S13, the data set may also be saved in the target document. In a specific implementation process, the target document may be a txt document, and the storage format of the data in the txt document may be arranged according to the storage address, as shown in fig. 2, which is a schematic diagram of storing the data in the target document, addr in fig. 2 represents the storage address, and value located in the same row as addr represents specific data stored in the storage address.
Taking the data set as an example of all the data burnt in the first camera module, after all the data burnt in the first camera module is stored in a target file, modifying the data to be modified in the target file into the target data based on the preset data modification rule. Namely, the target document is processed, the data to be modified in the target document is modified into the target data, and after the modification is completed, all the data in the target document is burnt into the second camera shooting module. Therefore, if a large amount of data needs to be modified, after all the data needing to be modified in the target document are completely modified, one-time data burning is executed for the second camera shooting module. It should be noted that the modification of the data in the target document may be automatically completed or may be manually completed.
In order to describe the data modification process in the embodiments of the present specification in detail, the following describes two cases, namely, taking the data to be modified as a calibration sequence and verifying the data as an example.
In the first case, the data to be modified is the calibration sequence to be modified.
In an implementation of this specification, when the data to be modified is a calibration sequence to be modified, the calibration sequence to be modified includes a target sequence segment corresponding to the calibration data, and the preset data modification rule includes a data modification rule of the target sequence segment, then step S13 may be implemented by: determining calibration data corresponding to the target sequence segment in the calibration sequence to be modified based on a data composition structure of the calibration sequence to be modified; and modifying the calibration data corresponding to the target sequence segment into the target data based on the preset data modification rule.
Specifically, since the calibration sequence usually has its own data composition format, and some sequence segments have fixed data that cannot be modified, for example, the data in the header sequence segment cannot be changed, it is necessary to determine the target sequence segment to be modified when modifying the calibration sequence. It should be noted that, for different types of calibration sequences, there are respective data composition structures corresponding to them, for example, the calibration sequence includes a header sequence, a data sequence, and a trailer sequence, and each data in the sequence corresponds to respective storage address information. Based on the data composition structure, the data corresponding to the target sequence segment can be accurately screened from the calibration sequence.
In the embodiment of the present specification, taking lens shading calibration data as an example, the calibration data set includes 1868 data, the first 68 data are header data, the data cannot be modified, the target sequence segment may be a data segment located between 300 and 500, and the preset data modification rule is to modify the calibration data of the target sequence segment to 00 or ff, and correspondingly, modify the data located between 300 and 500 to 00 or ff.
In the second case, the data to be modified is the verification data to be modified.
In this embodiment of the present specification, when the data to be modified is verification data to be modified, the preset data modification rule includes a calculation method of the verification data, and step S13 may be implemented in the following manner: determining source data used for calculating verification data in the target document; determining whether the source data is modified data; and if the source data are modified data, calculating modified verification data as the target data based on the source data and a preset data modification rule, and modifying the verification data to be modified into the target data.
The verification data may be selected according to actual needs, and for convenience of description, in this embodiment of the present specification, the verification data is checksum (checksum) as an example. For example, the auto white balance data may be associated with the checksum of the auto white balance data, the focus data may be associated with the checksum of the focus data, and the checksum of all the data may be associated with the checksum.
For different verification data, the preset data modification rule, i.e. the calculation mode of the verification data, may also be different. For example, when the CheckSum of the auto white balance data is calculated, the calculation manner of the verification data may be CheckSum (0x 0048-0 x 0050)% 0xFF + 1; when the checksum corresponding to all the data is calculated, the calculation mode of the verification data can be Sum (0x 0000-0 x3FF 3)% 0xFF + 1.
Taking the calculation method of checksum for calculating the auto white balance data as an example, since the calculation method needs to use the data (i.e., the source data) in the storage addresses 0x0048 to 0x0050 to perform the calculation, the source data needs to be determined in the data set. Further, if the source data is not modified, the checksum calculated based on the source data is also the same as the original checksum, and at this time, recalculation is not necessary. If the original data is modified, the checksum is also changed correspondingly, and at this time, the checksum needs to be recalculated based on the source data, and the original checksum is modified to the recalculated checksum.
It should be noted that, for the case where verification data needs to be calculated for each parameter data, for example, the checksum of the auto white balance data and the total checksum need to be calculated, in order to ensure that only one burning is performed on the camera module, all verification data can be directly changed in the target document, and the changed data is burned, so that a tedious burning manner of burning the checksum of the auto white balance data first and then calculating the total checksum is avoided, and thus, the burning times are reduced.
In step S104, after the data modification is completed, burning the modified data set into a second camera module, where the second camera module may be the same as the first camera module, that is, burning the data of the first camera module again; the second camera module can also be different from the first camera module, namely, the burning data of the first camera module is modified and burned into other camera modules.
In summary, in the method provided in this specification, the burning data of the first camera module is completely read out, the data is modified as needed, and the modified data set is burned at a time, so that batch processing of the burning data is realized, and the complexity of abnormal burning is reduced. Especially, when a large number of camera modules need to be subjected to abnormal burning, burning data can be copied into a target file, the data is modified through the target file, the modified data is burnt into each camera module at one time, complicated data burning does not need to be executed for each camera module, and burning efficiency of the camera modules is improved.
