Description

Technical Field

[0001] The present invention relates to the field of testing technology, and in particular to an anti-shake detection method and device. Background Art

[0002] At present, the camera modules of mobile phones all have anti-shake functions, so that the mobile phone can take clear photos even when it is shaking or swaying. The camera module is generally equipped with an OIS (Optical Image Stabilizer) anti-shake module. Before the camera module is assembled to other electronic devices such as mobile phones, the OIS anti-shake module of the camera module needs to be tested to ensure that the OIS anti-shake module operates normally. In the traditional testing process, the camera module needs to be installed on a vibration table with a gyroscope first, and the vibration table is used to simulate the vibration environment. After the gyroscope is corrected, the camera module shoots the test chart (chart chart) to obtain the static line width when the vibration table is static, the line width without anti-shake when the vibration table is turned on and there is no OIS, and the line width with anti-shake when the vibration table is turned on and OIS is turned on; finally, the compression ratio is calculated based on the static line width, the line width without anti-shake and the line width with anti-shake. According to the compression ratio, it can be judged whether the anti-shake of the camera module meets the requirements. However, it is difficult to make the vibration standards of the vibration table completely consistent during production, which will lead to inaccurate OIS test data of camera modules when using different vibration tables.

[0003] Therefore, when performing OIS testing on camera modules, differences in vibration platforms will cause large errors in the OIS test results. Summary of the invention

[0034] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] See also Figure 1 , shows a flow chart of an anti-shake detection method provided by a first embodiment of the present invention; the anti-shake detection method comprises:

[0036] Step S10: obtaining the anti-shake amplitude of the camera module when the anti-shake is turned on according to the vibration simulation signal, the gyro gain coefficient of the camera module and the reference coordinates of the camera module imaging; the vibration simulation signal is a signal of the standard vibration table vibrating according to a preset target vibration angle;

[0037] Step S20: obtaining a compression ratio of the camera module according to the anti-shake amplitude and a preset target vibration angle; the compression ratio is used to verify the anti-shake performance of the camera module.

[0038] An anti-shake detection method in this embodiment is applied to perform OIS detection on a camera module. It can be executed in a driver IC of the camera module, or a hardware module for execution can be separately set. In this embodiment, execution based on the driver chip is used as an example. The method in this embodiment changes the existing conventional detection method. During the entire detection process, a vibration table is no longer used for vibration detection. Instead, a vibration simulation signal collected in advance based on a standard vibration table is used to make the tested camera module perform an anti-shake response to obtain an anti-shake amplitude; finally, the compression ratio can be determined based on the anti-shake amplitude and the target vibration angle. Therefore, the entire detection process can ensure the high consistency of the detection basis and eliminate the detection error problem caused by the difference in the vibration table. The specific embodiments of each step of this embodiment are elaborated and explained in detail below.

[0039] Step S10: According to the vibration simulation signal, the gyro gain coefficient of the camera module and the reference coordinates of the camera module imaging, the anti-shake amplitude of the camera module when the anti-shake is turned on is obtained; the vibration simulation signal is a signal of the standard vibration table vibrating according to a preset target vibration angle.

[0040] In step S10, the vibration simulation signal is a vibration waveform obtained by using a preset detection unit to perform vibration detection on a standard vibration table, and vibrating at a standard vibration angle and standard frequency used in the test of the camera module to be tested. The detection unit can at least detect the vibration waveform of the standard vibration table in the X-axis and Y-axis directions, such as Figure 2 As shown; Figure 2 The figure shows the vibration waveform detected by the detection unit when the standard vibration table is vibrated at a standard frequency of 4HZ and a standard vibration angle of 1°. The X-axis and Y-axis are the two vibration directions on the standard vibration table, which can be defined based on the actual vibration direction of the vibration table. The standard vibration table refers to a vibration table with qualified vibration error, which does not need to be corrected, and its various parameters are optimal or close to optimal.

[0041] The detection unit can be a standard gyroscope or a Hall sensor capable of detecting vibration signals, without limitation. The vibration simulation signal detected by the detection unit can be stored in a memory and sent to the driving chip of the camera module through a signal transmitter when needed.

[0042] Gyro Gain is the compensation coefficient for the reverse anti-shake of the IC motor driven by the gyroscope when it senses external shaking. It is used to convert the shaking angle into the code value that the motor needs to respond to and compensate after the camera module sends the shaking. After the motor compensates for the shaking angle, it is possible to ensure that the final camera module imaging is not blurred.

[0043] The reference coordinates are one or more coordinates selected by the camera module after shooting a test chart or other images for testing. The reference coordinates can be used as a reference basis after the camera module is shaken to identify the offset of the camera module's response vibration simulation signal and gyro gain coefficient, that is, the anti-shake amplitude. The test chart in this embodiment can be a commonly used black cross chart. Furthermore, the position of the reference coordinates is not limited. In this embodiment, it can be preferably the center coordinates of the camera module imaging to avoid the influence of factors such as camera module imaging distortion and improve the test accuracy.

[0044] A specific implementation method for obtaining the anti-shake amplitude can be referred to as follows:

[0045] First, the gyro gain coefficient can be loaded, and the offset coordinates can be obtained according to the vibration simulation signal; the offset coordinates are the coordinates corresponding to the reference coordinates after compensation based on the gyro gain coefficient; then, the anti-shake amplitude is obtained according to the reference coordinates and the offset coordinates. Specifically, after the driver chip loads the gyro gain coefficient, it can respond based on the vibration simulation signal transmitted by the signal transmitter to generate an adjustment signal for the lens part of the camera module; the motor of the camera module can control the movement of the lens part of the camera module based on the adjustment signal. At this time, since the camera module is not installed on the vibration table, it only responds and adjusts based on the vibration simulation signal; therefore, after the camera module responds to the vibration simulation signal, its reference coordinates will be offset when it images again, that is, the offset coordinates are obtained. Since the imaging distance is known, the anti-shake amplitude can be determined according to the reference coordinates and the offset coordinates. This amplitude is the amplitude generated by compensating the vibration simulation signal based on the gyro gain coefficient after the camera module turns on OIS.

[0046] Step S20: obtaining a compression ratio of the camera module according to the anti-shake amplitude and a preset target vibration angle; the compression ratio is used to verify the anti-shake performance of the camera module.

[0047] In step S20, the target vibration angle is the upper limit of the angle at which the camera module vibrates when performing an OIS test on the camera module, that is, the maximum angle. It can be understood that the target vibration angle is the upper limit of the anti-shake performance requirement of the camera module. In this embodiment, at least two implementation methods are provided for step S20:

[0048] 1. Determine the compression ratio based on the amplitude. The specific steps are as follows:

[0049] First, the target amplitude is obtained according to the target vibration angle. Since the imaging distance of the camera module is known, the target amplitude can be calculated according to the target vibration angle and the imaging distance; that is, the ratio of the target amplitude to the imaging distance is the tangent of the target vibration angle, such as Figure 3 shown.

[0050] Then, the compression ratio of the camera module is obtained based on the anti-shake amplitude and the target amplitude. Specifically, it can be based on the formula The compression ratio is obtained; wherein SR is the compression ratio, B is the anti-shake amplitude, and T is the target amplitude; when the anti-shake performance of the camera module is better, the anti-shake amplitude and the target amplitude are closer, therefore, the above compression ratio calculation method can replace the existing solution.

[0051] Through the above processing, the compression ratio can be determined by using the anti-shake amplitude and the target amplitude. There is no need to actually install the camera module on a vibration table for shooting tests, thus avoiding errors in the test results caused by differences in the accuracy of the vibration table. Furthermore, based on the test method of this embodiment, there is no need to install the camera on a vibration table, nor is there any need to obtain the static line width of the camera module in a static state, and there is no need to start the vibration table to obtain the line width of the camera module with OIS started and without OIS started. Therefore, the anti-shake test method of this embodiment also saves process steps.

[0052] 2. Determine the compression ratio based on the vibration angle. The specific steps are as follows:

[0053] First, the anti-shake vibration angle is obtained according to the anti-shake amplitude. Since the imaging distance of the camera module is known, the anti-shake vibration angle can be calculated according to the anti-shake amplitude and the imaging distance; that is, the ratio of the anti-shake amplitude to the imaging distance is the anti-shake vibration angle, which can also be referred to Figure 3 The principle shown, then, the anti-shake vibration angle can be determined through inverse trigonometric functions.

[0054] Then, the compression ratio of the camera module is obtained according to the anti-shake vibration angle and the target vibration angle. Specifically, the compression ratio of the camera module can be obtained based on the formula The compression ratio is obtained; wherein SR is the compression ratio, B′ is the anti-shake vibration angle, and T′ is the target vibration angle; when the anti-shake performance of the camera module is better, the anti-shake vibration angle and the target vibration angle are closer, therefore, the above compression ratio calculation method can replace the existing solution.

[0055] Finally, the optical image stabilization effect of the camera module can be determined based on the obtained compression ratio. The larger the compression ratio, the better the optical image stabilization effect. The compression ratio threshold can be set according to the needs to screen the camera modules that meet the requirements. The camera module with a compression ratio greater than the compression ratio threshold is a qualified camera module.

[0056] Furthermore, in this embodiment, the first method mentioned above can be preferably used to implement; in the actual test process, the target vibration angle is generally 1° to 2°, and the corresponding anti-shake vibration angle is also near the value range of the target vibration angle; therefore, a large error may be generated when performing inverse trigonometric function processing and logarithmic processing. Therefore, in this embodiment, the first method mentioned above can further reduce the error and improve the test accuracy.

[0057] In summary, the anti-shake detection method provided in this implementation obtains the anti-shake amplitude of the camera module when the anti-shake is turned on according to the vibration simulation signal, the gyro gain coefficient of the camera module and the reference coordinates of the camera module imaging; the vibration simulation signal is a signal of the standard vibration table vibrating according to the preset target vibration angle; then, according to the anti-shake amplitude and the preset target vibration angle, the compression ratio of the camera module is obtained; the compression ratio is used to verify the anti-shake performance of the camera module. As a result, when using this method to perform anti-shake detection on the camera module, it is no longer dependent on the vibration table, avoiding the accuracy difference between different vibration tables and improving the detection accuracy; at the same time, it also saves the detection cost.
