Description

Technical Field

[0001] The present application relates to the technical field of camera module testing, and in particular to a glare testing device. Background Art

[0002] Glare is a visual phenomenon in which, due to the distribution of brightness across the field of view or excessively high light source brightness, there is an extreme contrast between the brightness of the light source and the background, causing discomfort or impaired visual perception. Glare can affect the visual environment and threaten human health, well-being, and work efficiency. Therefore, testing and evaluating glare is crucial.

[0003] The interference of glare on the camera module's video quality is mainly manifested in the following aspects: glare will reduce the contrast and clarity of the picture, making the picture look blurred, distorted or overexposed; glare will produce light spots or halos of different shapes and colors, affecting the beauty and authenticity of the picture; glare will change the color and color temperature of the picture, causing the picture to be discolored or lost; glare will interfere with the camera module's automatic exposure and autofocus functions, resulting in underexposure or inaccurate focus.

[0004] Currently, the mainstream detection method for existing glare testing devices for the stray light performance of camera modules is to manually adjust the incident angle and take a photo under a single point light source. This detection method is prone to missing some incident angles, has low efficiency, and is difficult to reproduce some flares, resulting in inaccurate detection and evaluation, affecting the debugging of image effects.

[0005] Some methods also use robotic arms and other methods to simulate different glare scenes by moving the camera module to test the glare resistance of the camera module. However, this method has the following disadvantages:

[0006] Installing a manipulator or robotic arm in the chamber will occupy space in the chamber and may affect the propagation of light, such as forming a shadow in the chamber, or blocking the light source and the camera module, causing the light to be unable to directly reach the camera module, thereby affecting the accuracy of the test results; installing a manipulator or robotic arm in the chamber will increase the complexity and cost of the test device, and will also increase the time and difficulty of the test process, reducing the efficiency and reliability of the test. Summary of the Invention

[0007] The present application provides a glare testing device, which is used to avoid the technical problem of low accuracy in testing electronic equipment using the glare testing device.

[0008] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0009] In a first aspect, a glare testing device is provided. The glare testing device is used to test a camera module of an electronic device. The glare testing device includes a carrying portion and a mounting portion mounted on the carrying portion. The mounting portion is used to mount the electronic device. The glare testing device also includes: a cover portion having a chamber disposed therein and removably covering the carrying portion to form an enclosed space therebetween; and a light source portion including a movable light source movably mounted on an inner sidewall of the cover portion to illuminate the electronic device mounted on the mounting portion.

[0010] The glare testing device provided in the embodiment of the present application can perform glare testing on the camera module of an electronic device in a confined space, thereby avoiding interference from external light and improving the accuracy and reliability of the test. At the same time, by changing the position and angle of the light source on the inner wall of the cover body by moving the light source, different glare scenes can be simulated to detect the glare anti-interference ability of the camera module. It is possible to avoid the use of methods such as installing a manipulator or a robotic arm in the chamber, which will affect the test results to a certain extent, such as forming a shadow in the chamber, or blocking the light source and the camera module, resulting in inaccurate test results. By movably installing the mobile light source on the inner wall of the cover body, while meeting the requirements of light source tests at different angles, the influence of structural obstruction and shadow on the test results is avoided, thereby improving test accuracy.

[0011] In one embodiment, a guide portion extending along the inner sidewall of the housing is provided, and the mobile light source is movably mounted on the guide portion. The guide portion allows for more precise movement of the mobile light source, simplifies the structure and operation of the glare testing device, and improves testing efficiency and reliability. For example, a simple mechanical structure such as a gear or rack can be used to drive the mobile light source along the guide portion, and a graduated portion can be used to mark the position and angle of the mobile light source, facilitating the recording and reproduction of test data.

[0012] In one embodiment, multiple movable light sources and guides are provided, spaced apart circumferentially along the housing and extending vertically along the inner sidewall. Each guide is movably provided with at least one movable light source. This glare testing device can be configured with multiple guides and movable light sources on the inner sidewall of the housing, thereby increasing the number and distribution of light sources, simulating a wider range of glare scenarios, and testing the glare immunity of the electronic device's camera module.

[0013] In one embodiment, the inner wall of the chamber is a curved surface. The curved inner wall allows the movable light source to move along different curvatures on the inner wall, thereby providing different light bending degrees and curvatures, simulating different glare sources and environments, such as illuminating the camera module from different curves such as arcs or ellipses, or illuminating the camera module from different curved surfaces such as different surface radii or eccentricities.

[0014] In one embodiment, the chamber is a hemispherical cavity, and the mounting portion is disposed at the center of the bottom of the hemispherical cavity. This allows the movable light source to maintain a constant distance from the camera module on the mounting portion during movement. This allows the intensity and quality of light to be unaffected by distance when the movable light source illuminates the camera module at different angles, thereby improving light utilization and stability and reducing light loss and interference.

[0015] In one embodiment, the light source unit further includes a first driving unit, which is arranged between the cover body and the mobile light source and is used to drive the mobile light source to move on the guide portion. By controlling the operating parameters of the first driving unit, the moving speed and direction of the mobile light source are adjusted, thereby improving the flexibility and controllability of the distribution and transformation of the light source to meet different test requirements. The operating parameters of the first driving unit can be set and adjusted through devices such as a computer or a remote control. According to different test requirements, the moving speed and direction of the mobile light source can be changed, thereby changing the distribution and transformation of the light source to meet the simulation of different glare scenes. For example, if you want to simulate a glare scene that dynamically changes the illumination of the camera module from different directions, you can control the moving speed and direction of the mobile light source to change randomly or periodically through the first driving unit, thereby generating different light source transformations and detecting the glare anti-interference ability of the camera module.

[0016] In one embodiment, the guide portion includes a guide groove formed on the inner sidewall and extending vertically along the inner sidewall. The movable light source is provided with a slider slidably mounted within the guide groove. This arrangement allows the slider to be more tightly and stably positioned within the guide groove, thereby improving the operating accuracy and stability of the slider, avoiding deviation and error of the slider, and enhancing the accuracy and efficiency of testing.

[0017] In one embodiment, a scale portion is provided on the inner side wall of the cover body portion, and the scale portion extends along the length direction of the guide portion. The test process can be made more standardized and normalized, thereby improving the reliability and effectiveness of the test. The existence of the scale portion can provide a unified reference standard for the tester, so that the tester can set and adjust the moving position and angle of the mobile light source according to the numerical value of the scale portion, thereby ensuring the consistency and accuracy of the test. Finally, the above-mentioned setting can also make the test results more comparable and verifiable, thereby improving the reproducibility and traceability of the test. A clear recording method can be provided for the tester, so that the tester can record and report the moving position and angle of the mobile light source according to the numerical value of the scale portion, thereby facilitating the comparison and verification of the test results.

[0018] In one embodiment, the support portion includes a base, the base being provided with a receiving groove, the receiving groove being adapted to fit within the lower edge of the cover portion, and when the cover portion is placed over the support portion, the lower edge of the cover portion is accommodated within the receiving groove. The receiving groove is adapted to fit within the lower edge of the cover portion, and when the cover portion is placed over the support portion, the lower edge of the cover portion is accommodated within the receiving groove, thereby forming a sealed structure, eliminating a gap between the cover portion and the support portion, and preventing external light from entering the interior of the glare testing device, affecting the distribution and transformation of light from the mobile light source, and interfering with the detection of the glare anti-interference capability of the camera module of the electronic device.

[0019] In one embodiment, the first driving part includes a rack and a driving motor assembly. The rack is fixed on the bottom wall of the accommodating groove and extends along the length direction of the accommodating groove. The driving motor assembly is arranged on the mobile light source. A gear is provided at the output end of the driving motor assembly, and the gear is engaged with the rack.

[0020] In one embodiment, the mounting portion includes: a base mounted on the supporting portion; a clamping portion for clamping the electronic device; and an adjustment portion mounted on the base, with an output end of the adjustment portion connected to the clamping portion for adjusting the angle of the clamping portion. By configuring the mounting portion to secure and adjust the position and angle of the electronic device, the electronic device can receive light from the light source at different directions and distances, thereby facilitating glare testing.

[0021] In one embodiment, the adjustment portion includes: a first automatic adjustment member, the first automatic adjustment member being disposed on the base, the first automatic adjustment member having a first output shaft, the first output shaft being perpendicular to the bearing portion; and a second automatic adjustment member, the second automatic adjustment member having a second output shaft, the output shaft of the second automatic adjustment member being perpendicular to the output shaft of the first automatic adjustment member, the second output shaft being drivingly connected to the clamping portion. The output shafts of the first and second automatic adjustment members are perpendicular to each other, enabling the clamping portion to rotate in two directions, thereby increasing the flexibility and controllability of the adjustment portion.

[0022] In one embodiment, a guide portion extending along the wall surface of the inner side wall is provided on the inner side wall of the cover body, and the movable light source is movably mounted on the guide portion; the light source portion further includes a first driving portion, which is provided between the cover body and the movable light source and is used to drive the movable light source to move on the guide portion; the glare testing device further includes: a control portion, which is electrically connected to the first driving portion and the adjustment portion and is used to control the operation of the first driving portion and the adjustment portion.

[0044] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0045] Glare is a visual phenomenon in which, due to the distribution of brightness across the field of view or excessively high light source brightness, there is an extreme contrast between the brightness of the light source and the background, causing discomfort or impaired visual perception. Glare can affect the visual environment and threaten human health, well-being, and work efficiency. Therefore, testing and evaluating glare is crucial.

[0046] The interference of glare on the camera module's video quality is mainly manifested in the following aspects: glare will reduce the contrast and clarity of the picture, making the picture look blurred, distorted or overexposed; glare will produce light spots or halos of different shapes and colors, affecting the beauty and authenticity of the picture; glare will change the color and color temperature of the picture, causing the picture to be discolored or lost; glare will interfere with the camera module's automatic exposure and autofocus functions, resulting in underexposure or inaccurate focus.

[0047] Currently, the mainstream detection method for existing glare testing devices for the stray light performance of camera modules is to manually adjust the incident angle and take a photo under a single point light source. This detection method is prone to missing some incident angles, has low efficiency, and is difficult to reproduce some flares, resulting in inaccurate detection and evaluation, affecting the debugging of image effects.

[0048] Some methods also use robotic arms and other methods to simulate different glare scenes by moving the camera module to test the glare resistance of the camera module. However, this method has the following disadvantages:

[0049] Installing a manipulator or robotic arm in the chamber will occupy space in the chamber and may affect the propagation of light, such as forming a shadow in the chamber, or blocking the light source and the camera module, causing the light to be unable to directly reach the camera module, thereby affecting the accuracy of the test results; installing a manipulator or robotic arm in the chamber will increase the complexity and cost of the test device, and will also increase the time and difficulty of the test process, reducing the efficiency and reliability of the test.

[0050] Specifically, please refer to Figures 1 to 10As shown, the glare testing device of the embodiment of the present application is used to test the camera module of an electronic device. The glare testing device includes a carrying portion 10 and a mounting portion 20 mounted on the carrying portion 10. The mounting portion 20 is used to mount the electronic device. The glare testing device also includes a cover portion 30 and a light source portion. A chamber 32 is provided inside the cover portion 30. The cover portion 30 is detachably covered on the carrying portion 10 to form a closed space 50 between the cover portion 30 and the carrying portion 10. The light source portion includes a movable light source 41. The movable light source 41 is movably mounted on the inner side wall of the cover portion 30 to illuminate the electronic device on the mounting portion 20.

[0051] The glare testing device of the embodiment of the present application can perform glare testing on the camera module of the electronic device in a confined space 50, thereby avoiding interference from external light and improving the accuracy and reliability of the test. At the same time, by changing the position and angle of the light source on the inner wall of the cover body 30 by moving the light source 41, different glare scenes can be simulated to detect the glare anti-interference ability of the camera module. It is possible to avoid the use of methods such as installing a manipulator or a robotic arm in the chamber 32, which will affect the test results to a certain extent, such as forming a shadow in the chamber 32, or blocking the light source and the camera module, resulting in inaccurate test results. By movably installing the mobile light source 41 on the inner wall of the cover body 30, while meeting the requirements of light source tests at different angles, the influence of structural obstruction and shadow on the test results is avoided, thereby improving test accuracy.

[0052] Specifically, when the cover body 30 is covered on the bearing part 10, a closed space 50 is formed between the cover body 30 and the bearing part 10. Only the light source inside the cover body 30 can enter this space, and external light cannot enter. Therefore, it can ensure that the test environment is constant and not affected by external light, thereby improving the accuracy and reliability of the test. The mobile light source 41 can move on the inner wall of the cover body 30, thereby changing the position and angle of the light source, so that different glare scenes can be simulated, such as illuminating the camera module from different directions such as above, below, left, right, front, and back, or illuminating the camera module from different distances, or illuminating the camera module from different intensities, etc. In this way, the performance of the camera module in different glare scenes can be tested and its glare anti-interference ability can be evaluated. The glare testing device adopts a mobile light source 41, which can avoid installing a manipulator or an arm in the chamber 32. These methods will occupy the space in the chamber 32 and may affect the propagation of light, such as forming a shadow in the chamber 32, or blocking the light between the light source and the camera module, resulting in the light not being able to directly illuminate the camera module, thereby affecting the accuracy of the test results.

[0053] The electronic device may be a device with a camera function, such as a mobile phone, tablet computer, laptop computer, camera, etc. The camera module generally refers to an electronic component for capturing images, including a lens, sensor, circuit board, etc.

[0054] It should be noted that the support portion 10 is the base for supporting the entire glare test device and can be a platform, a shelf, a table, etc. The chamber 32 is a space located inside the housing 30 and can be cylindrical, cubic, hemispherical, etc. The movable light source 41 is a light source that can be moved along the inner wall of the housing 30 and can be a bulb, a laser, a light-emitting diode, etc. Users can select different light sources to test the camera module glare.

[0055] See also Figure 2 and Figure 7 As shown, the inner sidewall of the housing 30 of the embodiment of the present application is provided with a guide portion 31 extending along the wall surface of the inner sidewall, and a movable light source 41 is movably mounted on the guide portion 31. The guide portion 31 enables the movable light source 41 to move along the inner sidewall of the housing 30 in different directions, thereby simulating different glare scenarios, such as illuminating a camera module from different angles, positions, and distances to test the camera module's glare resistance. The guide portion 31 can make the movement of the movable light source 41 more precise, simplify the structure and operation of the glare testing device, and improve the efficiency and reliability of the test. For example, the movable light source 41 can be driven to move along the guide portion 31 by a simple mechanical structure such as a gear or rack, or the position and angle of the movable light source 41 can be marked by a scale portion to facilitate the recording and reproduction of test data.

[0056] Among them, the guide part 31 can be a guide groove 311, which is a groove 221 opened on the inner wall and extending up and down along the inner wall. A slider 42 is provided on the mobile light source 41, and the slider 42 can be slidably installed in the guide groove 311. The mobile light source 41 is driven to move on the guide groove 311 through mechanical structures such as gears and racks. It has a simple structure, is easy to manufacture, and runs smoothly.

[0057] In another embodiment, the guide portion 31 can be a guide rail, which is a linear track fixed on the inner wall and extending up and down along the inner wall. The mobile light source 41 is provided with a ball or roller, which is rotatably installed on the guide rail, and the mobile light source 41 is driven to move on the guide rail by a transmission structure such as a motor and a belt.

[0058] In another embodiment, the guide portion 31 can be an annular guide chain, which is a chain fixed on the inner wall and extends up and down along the inner wall. A sprocket is provided on the mobile light source 41, and the sprocket is rotatably embedded in the annular guide chain. The mobile light source 41 is driven to move on the annular guide chain through a chain transmission structure such as a chain and a sprocket.

[0059] To simulate a wider range of glare scenarios, the embodiment of the present application includes multiple movable light sources 41 and guides 31. These guides 31 are spaced apart circumferentially around the housing 30 and extend vertically along the inner sidewall. Each guide 31 is movably mounted with at least one movable light source 41. This glare testing device can incorporate multiple guides 31 and movable light sources 41 on the inner sidewall of the housing 30, thereby increasing the number and distribution of light sources, simulating a wider range of glare scenarios and testing the glare immunity of the electronic device's camera module.

[0060] Specifically, the multiple guides 31 and the movable light sources 41 can cover different areas of the inner sidewall of the housing 30, thereby providing different light directions and intensities, simulating different glare sources and environments. For example, the camera module can be illuminated from different angles, such as the front, side, and oblique surface, or from different distances, such as close and long distances. Alternatively, the multiple movable light sources 41 can have different brightness levels, such as high brightness and low brightness, etc. This allows the performance of the camera module to be tested in different glare scenarios and its glare resistance to interference to be evaluated.

[0061] The glare testing device of the embodiment of the present application can achieve light source combinations and transformations by adjusting the position and angle of the mobile light sources 41 on different guide portions 31, simulating more complex glare scenarios and testing the glare resistance of the camera module of the electronic device. The mobile light sources 41 on different guide portions 31 can cooperate and coordinate with each other to form different light source combinations and transformations to simulate more complex glare scenarios, such as illuminating the camera module from multiple directions simultaneously, illuminating the camera module from different directions alternately, or illuminating the camera module from different directions in a dynamically changing manner, etc. This allows the performance of the camera module to be tested under different glare combinations and transformations, and its glare resistance can be evaluated.

[0062] In addition, at least one mobile light source 41 can be provided on each guide portion 31 to ensure that each guide portion 31 has a light source, thereby avoiding missing or overlapping light sources and improving the uniformity and effectiveness of the light source. The guide portion 31 extends up and down along the inner sidewall, allowing the mobile light source 41 to move both above and below the inner sidewall, thereby providing different light heights and inclinations, simulating different glare sources and environments, such as illuminating the camera module from high or low, or from a horizontal or oblique angle, etc. This allows the performance of the camera module to be tested at different glare heights and inclinations, and its glare resistance can be evaluated.

[0063] At the same time, the guide parts 31 extend up and down along the inner wall, so that the movable light source 41 has enough space to move in the upper and lower parts of the inner wall, thereby avoiding the movable light source 41 from colliding or rubbing with the top or bottom of the inner wall during movement, causing damage or wear to the movable light source 41 or the inner wall.

[0064] To facilitate simulation of varying light intensities, the movable light source 41 is replaceable. The guide portion 31 extends vertically along the inner sidewall, allowing the movable light source 41 to be installed and removed from both the upper and lower portions of the inner sidewall. This avoids the need for excessive adjustment or movement of the movable light source 41 during installation and removal, which could complicate or even endanger operations. This simplifies the installation and removal of the movable light source 41, improving operational convenience and safety.

[0065] In the embodiment of the present application, the inner wall of the chamber 32 is curved. By setting the inner wall as a curved surface, the curved inner wall can reflect light along the curved surface rather than along a straight line, thereby reducing light scattering and attenuation, increasing light concentration and brightness, improving light propagation and reflection, and preventing light from being reflected at right angles or diffusely on the inner wall. This improves light utilization and quality, and reduces light loss and interference.

[0066] Furthermore, by configuring the inner wall as a curved surface, the range and angle of movement of the mobile light source 41 can be increased, thereby simulating a wider range of glare scenarios and testing the glare resistance of the electronic device's camera module. The curved inner wall allows the mobile light source 41 to move along different curvatures on the inner wall, thereby providing different light curvatures and simulating different glare sources and environments. For example, illuminating the camera module from different curves, such as arcs or ellipses, or from different curved surfaces, such as those with different radii or eccentricities, can be performed. This allows the camera module's performance under different glare curvatures and radii to be tested, and its glare resistance can be evaluated.

[0067] See also Figure 4As shown, in a preferred embodiment, the chamber 32 of the embodiment of the present application is a hemispherical cavity, and the mounting portion 20 is arranged at the center position of the circle at the bottom of the hemispherical cavity. The mounting portion 20 is arranged at the center position of the circle at the bottom of the hemispherical cavity, so that the distance between the mobile light source 41 and the camera module on the mounting portion 20 can be kept unchanged during the movement, and the intensity and quality of the light can be unaffected by the distance when the mobile light source 41 illuminates the camera module at different angles, thereby improving the utilization rate and stability of the light and reducing the loss and interference of the light; it can also make the direction and inclination of the light unaffected by the distance when the mobile light source 41 illuminates the camera module at different angles, thereby improving the flexibility and controllability of the distribution and transformation of the light, simulating more glare scenes, and detecting the glare anti-interference ability of the camera module of the electronic device; it can also make the position and angle of the light unaffected by the distance when the mobile light source 41 illuminates the camera module at different angles, thereby improving the accuracy and consistency of the light, avoiding the deviation and error of the light, and improving the accuracy and efficiency of the test.

[0068] In order to achieve automatic adjustment of the position of the mobile light source 41, the light source unit of the embodiment of the present application also includes a first driving unit, which is arranged between the cover body 30 and the mobile light source 41 and is used to drive the mobile light source 41 to move on the guide portion 31. The mobile light source 41 is driven by a motor or hydraulic device of the first driving unit and can move along different directions and distances on the guide portion 31, thereby forming different light source combinations and transformations to simulate different glare scenes, such as irradiating the camera module from multiple directions at the same time, or irradiating the camera module alternately from different directions, or irradiating the camera module dynamically from different directions. For example, if you want to simulate a glare scene in which the camera module is illuminated from the left and right sides at the same time, the first driving unit can be used to control the mobile light sources 41 on the left and right sides to move simultaneously in the direction of the camera module, thereby generating a combination of two light sources to detect the glare anti-interference ability of the camera module. By controlling the operating parameters of the first driving unit, the moving speed and direction of the mobile light source 41 are adjusted, thereby improving the flexibility and controllability of the distribution and transformation of the light source to meet different testing requirements. The operating parameters of the first drive unit can be set and adjusted using a computer or remote control. The speed and direction of the mobile light source 41 can be changed to meet different testing requirements, thereby changing the distribution and transformation of the light source to simulate different glare scenarios. For example, to simulate a glare scenario where the camera module is illuminated from different directions, the first drive unit can be used to control the speed and direction of the mobile light source 41 to randomly or periodically change, thereby generating different light source transformations and testing the camera module's glare resistance.

[0069] In addition, the glare testing device can reduce the need for manual operation of the mobile light source 41 by being driven by the first drive unit, thereby improving the convenience and safety of operation and reducing the cost and risk of operation. The mobile light source 41 is driven by the first drive unit, eliminating the need for manual operation of the mobile light source 41, thereby avoiding the tediousness and danger of manual operation, improving the convenience and safety of operation and reducing the cost and risk of operation. For example, to simulate a glare scene in which a camera module is alternately illuminated from different directions, the first drive unit can control the speed and direction of the mobile light source 41 to switch in a certain order and time interval, thereby generating an alternation of different light sources and testing the camera module's glare resistance without the need for manual operation of the mobile light source 41, thereby saving manpower and time and improving efficiency and safety.

[0070] See also Figure 7 and Figure 10 In a preferred embodiment, the guide portion 31 of the embodiment of the present application includes a guide groove 311, which is formed on the inner side wall and extends up and down along the inner side wall. The movable light source 41 is provided with a slider 42, which is slidably mounted in the guide groove 311. Through the above arrangement, the slider 42 can be more tightly and stably mounted in the guide groove 311, thereby improving the operating accuracy and stability of the slider 42, avoiding deviation and error of the slider 42, and improving the accuracy and efficiency of the test. The cross-section of the guide groove 311 is trapezoidal, which allows the two sides of the slider 42 to fit tightly with the two sides of the guide groove 311, thereby reducing the gap and swing between the slider 42 and the guide groove 311, improving the accuracy and consistency of the position and angle of the slider 42, and also forming a locking structure between the two sides of the slider 42 and the two sides of the guide groove 311, thereby preventing the slider 42 from separating from the guide groove 311 during movement, causing damage or wear to the slider 42 or the guide groove 311.

[0071] In the embodiment of the present application, the inner sidewall of the cover portion 30 is provided with a scale portion, which extends along the length of the guide portion 31. This makes the moving position and angle of the mobile light source 41 on the guide portion 31 clearer and more visible, thereby facilitating the observation and recording of the motion state of the mobile light source 41, and improving the convenience and efficiency of the test. Specifically, the inner sidewall of the cover portion 30 is provided with a scale portion, which extends along the length of the guide portion 31 and can correspond to the slider 42 on the mobile light source 41, thereby displaying the moving position and angle of the mobile light source 41 on the guide portion 31, and facilitating the observation and recording of the motion state of the mobile light source 41. The inner sidewall of the cover portion 30 is provided with a scale portion, which extends along the length of the guide portion 31 and can correspond to the operating parameters of the first drive unit, thereby controlling the movement range and angle of the mobile light source 41 on the guide portion 31 to meet different testing requirements. This can make the testing process more standardized and normalized, thereby improving the reliability and effectiveness of the test. The presence of the graduated portion provides a unified reference standard for testers, allowing them to set and adjust the moving position and angle of the mobile light source 41 based on the numerical value of the graduated portion, thereby ensuring the consistency and accuracy of the test. Finally, the above-mentioned setting can also make the test results more comparable and verifiable, thereby improving the reproducibility and traceability of the test. It can provide testers with a clear recording method, allowing them to record and report the moving position and angle of the mobile light source 41 based on the numerical value of the graduated portion, thereby facilitating the comparison and verification of test results.

[0072] See also Figure 8As shown, the carrying portion 10 of the embodiment of the present application includes a base, on which a receiving groove 11 is provided. The receiving groove 11 is adapted to the lower edge of the cover portion 30. When the cover portion 30 is covered on the carrying portion 10, the lower edge of the cover portion 30 is received in the receiving groove 11. The receiving groove 11 is adapted to the lower edge of the cover portion 30. When the cover portion 30 is covered on the carrying portion 10, the lower edge of the cover portion 30 is received in the receiving groove 11, thereby forming a sealed structure, so that there is no gap between the cover portion 30 and the carrying portion 10, preventing external light from entering the interior of the glare testing device, affecting the distribution and transformation of light from the mobile light source 41, and interfering with the detection of the glare anti-interference capability of the camera module of the electronic device. In addition, the support portion 10 includes a base with a receiving groove 11 formed therein. The receiving groove 11 mates with the lower edge of the cover portion 30. When the cover portion 30 is placed over the support portion 10, the lower edge of the cover portion 30 is received within the receiving groove 11, thereby forming a sealed structure. This provides a more secure and tight connection between the cover portion 30 and the support portion 10, prevents the cover portion 30 from loosening or falling off, and ensures the structural integrity and stability of the glare testing device. The receiving groove 11 mates with the lower edge of the cover portion 30. When the cover portion 30 is placed over the support portion 10, the lower edge of the cover portion 30 is received within the receiving groove 11, thereby forming a simple structure. Installation and removal of the cover portion 30 from the support portion 10 requires only placing the lower edge of the cover portion 30 into or out of the receiving groove 11, without requiring any other fixing or connection methods. This reduces the time and difficulty of installation and removal, and improves operational convenience and efficiency.
