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 is functioning normally.

[0036] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although 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. Rather, 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.

[0037] In an embodiment of the present invention, a method for detecting stabilization of an optically stabilized image (OIS) module is provided. This method can be used to detect the stabilization performance of a camera module's optically stabilized image (OIS) module. During the detection process, a vibration platform is not required to provide a vibration environment for the camera module, thereby ensuring high detection consistency and reducing costs. The method according to an embodiment of the present invention is described in detail below using specific examples.

[0038] See also Figure 1 In one embodiment of the present invention, an anti-shake detection method is provided, the method comprising:

[0039] Step S10: When the anti-shake module of the camera module to be tested is turned off, a target object in a preset picture board video is photographed to obtain a first image; the target object in the picture board video shakes according to the preset shaking data;

[0040] Step S20: When the anti-shake module of the camera module to be tested is turned on, the shaking data is received, and the target object in the picture board video is photographed to obtain a second image;

[0041] Step S30: Based on the first image and the second image, a compression ratio of the camera module to be tested is obtained; the compression ratio is used to verify the anti-shake performance of the camera module to be tested.

[0042] In steps S10-S30 in this embodiment, the first image is obtained by acquiring the first image collected by the camera module under test when the anti-shake module (i.e., the OIS module is closed) is closed, and the first image is collected by the target object in shaking. Since the anti-shake function of the camera module under test is closed at this time, the first image at this time can be equivalent to the camera module under test collecting a stationary target object when shaking according to the shaking data. At this time, the use of a vibration table to provide a vibration source for the camera module under test is avoided. Then, the anti-shake function of the camera module under test is turned on, and the shaking data is directly input to the camera module under test, and the camera module under test is equivalent to obtaining the shaking data collected by the gyroscope; at this time, the driving chip of the camera module under test will recognize that the camera module under test is in a shaking state consistent with the shaking data, and the current shaking state is compensated for anti-shake; therefore, at this time, the camera module under test is in a shaking state and the anti-shake compensation is turned on, and the second image is collected by the target object in shaking. The state of the camera module in the shaking state and the anti-shake module is simulated to shoot the stationary target object, thereby avoiding the use of a vibration table. Finally, based on the first image and the second image, the compression ratio of the camera module under test can be determined, thereby realizing the anti-shake performance detection of the camera module under test. The specific possible implementation of each step of the method is described below.

[0043] Step S10: When the anti-shake module of the camera module under test is closed, the target object in the preset chart video is shot to obtain a first image; the target object in the chart video shakes according to preset shaking data.

[0044] In step S10, the camera module under test has an OIS module, and the anti-shake module is closed, i.e., the OIS module is closed. The shaking angle corresponding to the shaking data meets the test condition for testing the camera module under test, i.e., the shaking angle corresponding to the shaking data is the same as the shaking angle when the standard vibration table is used to test the camera module under test.

[0045] In this embodiment, the target object is a test chart played by a preset chart video, which is called a chart in the technical field; for example, the chart can be fixed on a vibration source to vibrate, and a recording tool is used to record the test chart to obtain a chart video. Then, the chart video is photographed to obtain a first image, as shown in Figure 2

[0046] ​First, shake the preset test plate according to the jitter data. For example, the test plate can be fixed on a vibration table that has been calibrated by the standard, and then the vibration table can be controlled to vibrate according to the jitter angle curve corresponding to the jitter data. Next, record the test plate in the shaking state to obtain a plate video; this plate video can be used as the target object. When recording, a high frame rate can be used to achieve a better simulation effect; for example, 120 frames, 175 frames, 240 frames, and so on. For the camera module under the same type of test conditions, this method only requires the use of the vibration table once, and at most only requires the calibration of the vibration table once. The obtained plate video can be used repeatedly as a target object, which greatly reduces the hardware cost and time cost and improves the detection efficiency.

[0047] The test pattern used can be a crosshair pattern or a dot pattern, ensuring accurate determination of the line width or shadow width in the first and second images. In this embodiment, a crosshair pattern is used as an example. Alternatively, other test patterns with identification mark patterns can be used without limitation. When the camera module under test, without the anti-shake module activated, captures the identification mark in a shaken state, a first image with the identification mark's shadow can be obtained.

[0048] Step S20: When the anti-shake module of the camera module to be tested is turned on, the shaking data is received, and the target object in the picture board video shooting is photographed to obtain a second image.

[0049] In step S20, a preset processor may be used to simulate and generate jitter data, and output it to the camera module to be tested. Specifically, the anti-shake function of the camera module to be tested is first turned on, and the jitter data simulated and generated by the preset processor is output to the camera module to be tested. For example, an MCU (Microcontroller Unit) may be used to simulate and generate jitter data according to a preset program, and the jitter data may be output as angle data obtained by integral operation, and the angle data may be output as the angle data obtained by integral operation. This ensures that the driver chip of the camera module to be tested can read and identify, without the need for secondary calculation, thereby improving test efficiency and accuracy. Then, after receiving the angle data, the camera module to be tested is controlled to shoot the target object to obtain a second image. At this time, the camera module to be tested receives the jitter data and identifies its own state as a jitter state, and the anti-shake module will perform jitter compensation on the target object based on the jitter data, thereby obtaining a second image after anti-shake compensation, such as Figure 3 shown.

[0050] Step S30: Based on the first image and the second image, a compression ratio of the camera module to be tested is obtained; the compression ratio is used to verify the anti-shake performance of the camera module to be tested.

[0051] One implementation of step S30 may be as follows: determine a first shadow width corresponding to the first image and a second shadow width corresponding to the second image; the first shadow width is the width of the transition area between the identification mark and the image background in the first image; the second shadow width is the width of the transition area between the identification mark and the image background in the second image. The image background refers to the image area outside the identification mark. Finally, based on the first shadow width and the second shadow width, obtain a compression ratio; specifically, calculate the compression ratio based on SR1=20*log10(S1 / S2), as follows: Figure 2-3 As shown, SR1 is the compression ratio, S1 is the first shadow width, and S2 is the second shadow width.

[0052] In other implementations, the following steps may be performed: obtaining a reference image, where the reference image is obtained by photographing a stationary target object by the camera module to be tested; then obtaining a reference shadow width in the reference image, where the reference shadow width is the width of the transition area between the identification mark and the image background in the reference image. Finally, based on the first shadow width, the second shadow width, and the reference, a compression ratio is obtained; that is, the compression ratio may be calculated based on SR2=20*log10((S1-S0) / (S2-S0)), as follows: Figure 2-4 As shown, SR2 is the compression ratio, S1 is the first shadow width, S2 is the second shadow width, and S0 is the reference shadow width.

[0053] In summary, an anti-shake detection method is provided in this embodiment, which is achieved by obtaining a first image captured by the camera module to be tested when the anti-shake module is turned off, the first image is obtained by capturing a shaking target object, and the target object is shaken according to preset shake data; and obtaining a second image captured when the camera module to be tested is turned on the anti-shake module and receives shake data, the first image is obtained by capturing a stationary target object; based on the first image and the second image, the compression ratio of the camera module to be tested is obtained, and the compression ratio is used to verify the anti-shake performance of the camera module to be tested. During the execution of the entire method, the first image and the second image are captured based on the shake data, and there is no need for a vibration table to provide a vibration source for the camera module to be tested. Therefore, for camera modules with the same type of requirements, it is sufficient to control the shake data to remain unchanged, and there is no need to test and calibrate the vibration table, which greatly reduces the hardware cost and time cost and improves the detection efficiency.
