DETAILED DESCRIPTION
[0018] The embodiment of the present application provides a light source board configuration method, which can ensure the light source stability and correctness of a single light source board in multiple switching of multispectral and multicolor temperature illuminance, and realize the use of corresponding spectral curve parameters of a light source board under different light source information (color temperature illuminance) for testing, thereby improving the test efficiency and reducing the hardware cost.
[0019] The technical scheme of the embodiment of the present application is to solve the above technical problem, and the general idea is as follows: A light source board configuration method applied to a light source modulation controller, the light source modulation controller being configured to be electrically connected with a light source board, the method comprising: obtaining a plurality of groups of spectral information for setting the light source board, wherein each group of spectral information comprises spectral curve parameters corresponding to different light source control standards; configuring the plurality of groups of spectral information in different channels of the light source board respectively, and establishing a corresponding relationship between the channels and the spectral information; obtaining a target switching mode of the light source board; and switching the channels of the light source board based on the target switching mode, switching the light source board to a spectral information state required by a camera module to be tested, and completing the configuration of the light source board.
[0020] In order to better understand the above technical scheme, the above technical scheme will be described in detail below in combination with the drawings of the specification and the specific embodiments.
[0021] In the first aspect, the embodiment of the present application provides a light source board configuration method applied to a light source modulation controller, the light source modulation controller being configured to be electrically connected with a light source board, and specifically, as shown in Figure 1 The method comprises the following steps S101 to S104: Step S101, obtaining a plurality of groups of spectral information for setting the light source board, wherein each group of spectral information comprises spectral curve parameters corresponding to different light source control standards.
[0022] It should be noted that the light source board configuration method provided by the present application can be applied to light source boards produced by different manufacturers.
[0023] Specifically, obtaining a plurality of groups of spectral information for setting the light source board can comprise: obtaining a plurality of groups of spectral information for setting the light source board according to the type of the camera module to be tested. If different types of camera modules are tested, different light source boards need to be configured.
[0024] Obtaining a plurality of groups of spectral information for setting the light source board can comprise: obtaining a plurality of color temperature and illumination spectral curve parameters used when the light source board is tested for multiple spectrums and light source control standards corresponding to the spectral curve parameters. The light source control standards can comprise color temperature (i.e. color temperature and illumination), chroma difference and spectral difference.
[0025] The chroma difference represents the coordinate difference of two colors in the uniform chroma space, and is used to measure the degree of color deviation perceived by the human eye. The spectral difference represents the difference between the spectral power distributions of two light sources, and is used to evaluate the spectral matching degree.
[0026] In the actual configuration process, the color temperature and illumination spectral curve parameters and the light source control standards used for multiple spectrums can be directly determined with the customer. For example, as shown in Figure 2As shown, the correlated color temperature range, chromaticity difference (Δuv range) and spectral difference (Spec Diff range) of different light sources such as D50, TL84, A light. The correlated color temperature of light source D50 is CCT = 4900-5100K, the correlated color temperature of light source TL84 is CCT = 3900-4100K, and the correlated color temperature of light source A is CCT = 2800-2950K; the chromaticity difference of light source D50 is Δuv = 0.000~+0.006, the chromaticity difference of light source TL84 is Δuv =-0.002~+0.004, and the chromaticity difference of light source A is Δuv =-0.002~+0.004; the spectral difference of light source D50 is Spec Diff <20%, the spectral difference of light source TL84 is Spec Diff <40%, and the spectral difference of light source A is Spec Diff <30%. The light source control standards of each light source are recorded as the basis for subsequent testing and light source control.
[0027] As shown in Figure 2 , the spectral curve parameters corresponding to different light source control standards, wherein the abscissa of the spectral curve is wavelength, unit is nanometer, and the ordinate is absorbance.
[0028] Step S102, the plurality of groups of spectral information are respectively configured in different channels of the light source board, and the correspondence between the channels and the spectral information is established; Specifically, a light source modulation controller is used to control a single light source board in multiple channels, and different channels control and distribute different color temperature illuminance and spectral curve parameters. As shown in Figure 3 , channel 1 corresponds to color temperature 5000K, illuminance 500Lux, and controls the corresponding spectral curve parameters in the open state; channel 2 corresponds to color temperature 4000K, illuminance 500Lux, and channel 3 corresponds to color temperature 2858K, illuminance 500Lux. Each channel has an independent control switch, and each control switch is electrically connected with the light source modulation controller. The control switch can be selected to be opened or closed according to the requirement, so as to realize the switching of different color temperature illuminance and spectral curve parameters on a single light source board.
[0029] On the same light source board, the camera module is used to test the use of different spectral curve parameters under the switching of different color temperature illuminance.
[0030] As an example, the light source modulation controller first imports a plurality of groups of spectral information into a plurality of light source boards, and then selects a relatively stable light source board. The light source board is used as a main light source board, and a plurality of groups of spectral information are respectively configured in different channels of the main light source board, and the correspondence between the channels and the spectral information is established.
[0031] Step S103, obtaining the target switching mode of the light source board; In step S104, the switching of the light source board channels is performed based on the target switching mode, and the light source board is switched to a required spectral information state of the camera module to be tested, thereby completing the configuration of the light source board.
[0032] In a specific implementation process, the target switching mode of the light source board can include: switching the on-off state of each channel in the light source board to perform round-robin testing on the camera module by using multiple light sources emitted by the light source board, and then performing round-robin testing on multiple camera modules of the same type one by one after the testing is completed to obtain all test results; and determining the target switching mode of the light source board according to the test results.
[0033] Switching the on-off state of each channel in the light source board can test the camera module. Specifically, for the on-off state of each channel in the light source board, different switching sequences and switching durations can be used for control to obtain test results under different switching sequences when the switching duration is the same, and test results under different switching durations when the switching sequence is the same.
[0034] For example, the switching method can be white light testing for 10 seconds, yellow light testing for 5 seconds, and then white light and yellow light testing together for 15 seconds. The camera module is tested in a cycle by using the switching method, and the result after each test is obtained, for example, 5-10 cycles of round-robin testing are performed.
[0035] After round-robin testing on the same camera module, in order to ensure the sufficiency of the test results, the same test needs to be continued on multiple camera modules of the same type.
[0036] From the obtained test results, the test result that ensures that a single light source board is stable when switching multiple channels and meets the standard requirements and the batch testing requirements of the module is found, and the switching method corresponding to the test result is used as the target switching mode.
[0037] The obtained target switching mode can be applied to the test of the camera module based on the light source board of the same configuration, and the light source of the light source board is switched by using the target switching mode.
[0038] Further, in order to improve the accuracy of the target switching mode, after the target switching mode of the light source board is determined, the target switching mode can also include: verifying multiple light source boards of the same configuration as the light source board by using the target switching mode; and optimizing the target switching mode according to the verification test result. By verifying a batch of other light source boards, it is ensured that the other light source boards are also stable and meet the standard requirements of the mother light source.
[0039] Thus, on the same light source board, the camera module is tested under different color temperature and illumination conditions, a large amount of verification test data is obtained, and the verification test data is used to find the best target switching mode.
[0040] On the same light source board, the camera module is tested under different color temperature and illumination conditions, a large amount of verification test data is obtained, and the verification test data is used to find the best target switching mode.
[0041] Specifically, the verification process includes: based on the light source board configured in advance (regarded as the mother light source board), the camera module is used to perform a cycle verification on the light source board, and then a batch of camera modules are used to perform the same cycle verification test. The switching sequence of the multi-spectrum corresponding to different color temperature and illumination can be set in various combinations according to actual needs.
[0042] In specific embodiments, the switching of the light source board channel based on the target switching mode switches the light source board to the required spectral information state of the camera module to be tested, completes the configuration of the light source board, which can include: installing and debugging the light source modulation controller, connecting the light source modulation controller with a single light source board; setting the color temperature and illumination, spectral curve parameters of different channels on the light source modulation controller according to the determined spectral information, and setting the switching state of each channel to ensure that the light source board can output different test conditions according to the set requirements, and switch the light source board to the required spectral information state of the camera module to be tested, complete the configuration of the light source board. The camera module to be tested is tested based on the configured light source board.
[0043] In the actual test process, the light source modulation controller can be controlled by software to switch the light source board to the required color temperature and illumination and spectral curve parameter state. For example, if the performance of the camera module under D50 color temperature is to be tested, the light source board is switched to the corresponding color temperature and spectral curve parameter of D50.
[0044] It can be understood that the light source modulation controller can control the channels, each channel independently controls the corresponding color temperature and spectral curve parameter, and the channels do not interfere with each other and can be independently turned on or off. In multiple tests, the environmental conditions of each test remain consistent, including the temperature, humidity and surrounding light environment of the test site, etc.
[0045] During the test of the camera module to be tested, the light source modulation controller can monitor the working state of the light source board in real time, and if an abnormality occurs, the test is immediately stopped and corresponding processing is performed.
[0046] The test process of the camera module can include: starting line test, starting test software; switching the light source environment, switching the light source board to the required color temperature and spectral curve parameter state; using the switched light source board to test the camera module; after the test is completed, the line test is ended. The test data is sorted and analyzed to determine whether the camera module meets the quality standard.
[0047] Then, after completing the configuration of the light source board, based on the multiple sets of spectral information and the target switching mode, other light source boards are configured in batches to obtain multiple configured light source boards, and the consistency of the other light source boards with the main light source board is good.
[0048] Further, in order to ensure the accuracy of the light source board, during the test process, professional test equipment can be used to detect the imaging quality, color restoration degree, and photosensitivity of the camera module. The working state of the light source board is monitored in real time. If problems such as brightness abnormality and color temperature deviation are found in the light source board, the test is immediately stopped, and the light source board is checked and processed.
[0049] Further, in order to ensure that the configured light source board maintains good performance, before, during, and after batch production, the point inspection test of the multiple configured light source boards can be performed every interval of a preset time length.
[0050] Optionally, the preset time length can be 1 day, 1 week, or 1 month, etc. For example, the point inspection test of the multiple configured light source boards is performed every week.
[0051] In specific embodiments, the point inspection test of the multiple configured light source boards can include: sending a set of spectral information in the multiple sets of spectral information to a configured light source board to set, obtaining a mother light source board; testing a randomly selected camera module under the mother light source board, recording the test result as a standard value, and recording the randomly selected camera module as a target camera module, wherein the target camera module is of the same type as the camera module to be tested; testing the target camera module under the other configured light source boards to obtain respective test values of each light source board; comparing the test values with the standard value for each test value, and determining whether the configured light source board meets the set requirements according to the comparison result.
[0052] After the current set of spectral information in the multiple sets of spectral information is tested, the same test is performed on the other sets of spectral information in the multiple sets of spectral information to complete the test of all the spectral information in the multiple sets of spectral information.
[0053] Specifically, the comparison of the test value and the standard value, and the judgment of whether the configured light source board meets the set requirement according to the comparison result can include: comparing the value obtained by subtracting 1 from the ratio of the standard value to the test value with the preset deviation; if the value is less than the preset deviation, it is determined that the configured light source board meets the set requirement; if the value is greater than or equal to the preset deviation, it is determined that the configured light source board does not meet the set requirement.
[0054] Optionally, the preset deviation can be 0.2-0.5%.
[0055] In specific embodiments, the point inspection test on the configured multiple light source boards can include: sending the light source color temperature and spectral curve parameters to the light source board for setting using the CL200 illuminometer tool, and the light source board is defined as a mother light source; randomly selecting a camera module to test under the mother light source, and the test value at this time is recorded as a standard value, and the camera module number is recorded as No. 1 module; using No. 1 module to test under other light source boards, and comparing the test values obtained under other light source boards with the standard value, the difference calculation formula is: (standard value / test value)-1<0.3%, which meets the difference calculation requirement, and it is considered that the light source board meets the requirement, otherwise it is considered that the light source board does not meet the requirement.
[0056] For example, the product test can include detecting the imaging quality, color restoration degree, and photosensitivity of the camera module, and the like. For example, the test value here can be an RGB value.
[0057] Further, in order to ensure the stability and correctness of the light source of the configured light source board, after it is determined that the configured light source board does not meet the set requirement, the method can further include: recalibrating the configured light source board.
[0058] The recalibration of the configured light source board can include: connecting the light source board and the illuminometer tool through a data line; and sending the spectral information to the light source board through the data line for setting and calibration.
[0059] Specifically, the calibration operation is to send the light source color temperature and spectral curve parameters to the light source board for setting and calibration through the CL200 illuminometer tool connected through the data line.
[0060] The present application can realize the point inspection of the light source board according to the aforementioned light source point inspection period control and light source point inspection standard control ((standard value / test value)-1<0.3%) in the production line batch operation process, and periodically inspect the light source board according to the set frequency, to ensure that the light source board continuously and stably meets the test requirements, and to utilize the light source point inspection module to control the correctness and stability of the light source switching multi-spectral color temperature and illuminance, to prevent defective products from flowing out.
[0061] For example, according to the set light source point inspection standard and the point inspection time length, such as once every day before starting work and once every 4 hours. For the marked light source board that does not meet the requirements, the light source illuminometer is used for re-calibration, and after calibration, the point inspection is performed again. If it still does not meet the requirements, the light source board is isolated and is not used for testing.
[0062] As shown in Figure 4 , the light source board point inspection process can include: light source board mass production, starting test software, if the light source point inspection period has not arrived, the production line is normally operated, if the light source point inspection period arrives, the light source point inspection is performed, the point inspection result is judged whether it meets the standard, if it meets, the production line is normally operated, if it does not meet, re-calibration is performed, and after re-calibration, the light source point inspection step is repeatedly executed.
[0063] As shown in Figure 5 , for comparison between the traditional test process (process 1) and the test process (process 2) proposed by the application, the traditional test process is: the production line starts testing, (light source environment switching), product testing is performed using No. 1 light source board, (light source environment switching), product testing is performed using No. 2 light source board, (light source environment switching), product testing is performed using No. 3 light source board, and the production line ends testing. The test process of the application is: the production line starts testing, (light source environment switching), product testing is performed using No. 1 light source board, and the production line ends testing.
[0064] The application determines the multi-spectrum use color temperature illuminance spectrum curve parameters and light source control standards, and then uses a light source modulation controller to control a single light source board in multiple channels. Different channels control and distribute different color temperature illuminance and spectrum curve parameters. On this basis, using an infrared camera module, different spectrum curve parameters corresponding to different color temperature illuminances are tested multiple times under switching. By obtaining a large amount of verification data, a better switching method is found. By realizing the switching of different spectrum curve parameters corresponding to different color temperature illuminances on the same light source board and finding the best switching method, the utilization rate of a single light source board is greatly improved. Compared with the traditional test method, the dependence on multiple light source boards is reduced, and the hardware procurement cost is effectively reduced.
[0065] The light source board configured by the method is used for testing of the camera module, simplifies the test process, reduces the operation of frequent switching of the light source board, and greatly improves the production test efficiency of the production line.
[0066] The light source point inspection method can effectively control the correctness and stability of the light source switching multi-spectrum color temperature illuminance, ensure the correctness of the light source board color temperature illuminance and spectrum curve parameters during product testing, prevent the flow of defective light source boards, and improve the accuracy and reliability of product testing.
[0067] In summary, by adopting the target switching mode obtained to configure the light source board, the light source stability and correctness of a single light source in multiple switching of multispectrum and multicolor temperature illuminance can be ensured, the correctness of the light source board color temperature illuminance and spectrum curve parameters in product testing can be ensured, the defective products of the light source board can be prevented from flowing out, the module batch testing requirements can be met, and the method can realize corresponding different spectrum switching tests of a light source board under different light source information (color temperature illuminance) for testing and use, and the utilization rate of a single light source board is effectively improved.
