Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

In the embodiment of the present invention, an anti-shake detection method is provided, which can be used to detect the anti-shake performance of the OIS anti-shake module of the camera module. During the detection process, it is not necessary to use a vibration table to provide a vibration environment for the camera module. Guarantees high detection consistency and low cost. The method of the embodiment of the present invention will be described and described in detail below through specific examples.

Referring to FIG. 1, an embodiment of the present invention provides an anti-shake detection method, which includes:

Step S10: when the camera module to be tested turns off the anti-shake module, the target object in the preset video of the board is photographed to obtain a first image; the target object in the video of the board is shaken according to the preset shaking data ;

Step S20: when the camera module to be tested turns on the anti-shake module, receiving the shaking data, and shooting the target object in the video shooting of the drawing board to obtain a second image;

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

In this embodiment, in steps S10-S30, the camera module to be tested collects the first image when the anti-shake module is turned off (ie, the OIS module is turned off), and the first image is obtained by collecting the shaking target object. Since the anti-shake function of the camera module to be tested is turned off at this time, the first image at this time can be equivalent to the acquisition of a stationary target object when the camera module to be tested shakes according to the shaking data. At this time, the use of a vibration table to provide a vibration source for the camera module to be tested is avoided. Next, turn on the anti-shake function of the camera module to be tested, and directly input the jitter data to the camera module to be tested. The camera module to be tested is equivalent to obtaining the jitter data collected by the gyroscope; The driver chip will recognize that the camera module to be tested is in a jitter state that matches the jitter data, and perform anti-shake compensation for the current jitter state; A second image is obtained by collecting the shaking target object. In this way, when the camera module is in a shaking state and the anti-shake module is turned on, the state of shooting a stationary target object is simulated, 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 to be tested can be determined, thereby realizing anti-shake performance detection of the camera module to be tested. The specific possible implementation of each step of the method is described below.

Step S10: when the camera module to be tested turns off the anti-shake module, the target object in the preset video of the board is photographed to obtain a first image; the target object in the video of the board is shaken according to the preset shaking data .

In step S10, the camera module to be tested has an OIS module, and turning off the anti-shake module means turning off the OIS module. The shaking angle corresponding to the shaking data conforms to the test conditions for testing the camera module to be tested, that is, the shaking angle corresponding to the shaking data corresponds to the shaking angle corresponding to the camera module to be tested using a standard shaking table.

In this embodiment, the target object is a test drawing board that uses a preset drawing board video to play, which is called a chart drawing board in the technical field; for example, the chart drawing board can be fixed on a vibration source to vibrate, and Use a recording tool to record the test board to obtain a board video. Then, the video of the board is photographed and collected to obtain a first image, as shown in FIG. 2 . details as follows:

First, shake the preset test board according to the shaking data. For example, the test chart can be fixed on the vibration table after standard calibration, and then the vibration table can be controlled to vibrate according to the shaking angle curve corresponding to the shaking data. Next, record the test board in a shaking state to obtain a board video; the board video can be used as a target object. When recording, you can use high frame rate recording to achieve better analog effects; for example, 120 frames, 175 frames, 240 frames, and so on. For the camera module under the same test conditions, this method only needs to use the vibration table once, and at most only need to calibrate the vibration table once. The obtained board video can be used repeatedly as the target object, which greatly reduces the hardware cost and time cost, and improves the detection efficiency.

The test chart used can be a cross chart or a dot chart, which can ensure that the line width or shadow width in the obtained first image and the second image can be accurately determined. In this embodiment, a cross diagram is used as an example for description. In addition, other test charts with identification mark graphics can also be used without limitation. When the camera module to be tested without the anti-shake module turned on captures the identification mark in a shaking state, a first image with the shadow of the identification mark can be obtained.

Step S20 : when the camera module to be tested turns on the anti-shake module, the shaking data is received, and the target object in the video shooting of the drawing board is photographed to obtain a second image.

这样可保证待测摄像模组的驱动芯片可读取识别，无需进行二次计算，提高测试效率和准确度。然后，在接收到角度数据后控制待测摄像模组对目标对象进行拍摄，获得第二图像。此时，待测摄像模组接收到抖动数据，将对自身的状态识别为抖动状态，并且防抖模块将基于该抖动数据对目标对象进行抖动补偿，从而得到防抖补偿后的第二图像，如图3所示。In step S20, a preset processor may be used to simulate the generation of jitter data, and output the data to the camera module to be tested. Specifically, firstly, the anti-shake function of the camera module to be tested is enabled, and the jitter data simulated and generated by the preset processor is output to the camera module to be tested. For example, a MCU (Microcontroller Unit, Micro Control Unit) can be used to simulate and generate jitter data according to a preset program, and the jitter data can be output as angle data obtained by integral operation, angle data

In this way, the driver chip of the camera module to be tested can be read and identified, and no secondary calculation is required, thereby improving the test efficiency and accuracy. Then, after receiving the angle data, the camera module to be tested is controlled to photograph the target object to obtain a second image. At this time, the camera module to be tested receives the shaking data, and recognizes its own state as a shaking state, and the anti-shake module will perform shaking compensation on the target object based on the shaking data, so as to obtain a second image after anti-shake compensation, As shown in Figure 3.

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

An implementation manner in step S30 may be as follows: determine the width of the first shadow corresponding to the first image and the width of the second shadow corresponding to the second image; the width of the first shadow is between the identification mark in the first image and the image background The width of the transition area; the width of the second shadow is the width of the transition area between the identification mark in the second image and the image background. The image background refers to the area of the image outside the identification marker. Finally, the compression ratio is obtained based on the first shadow width and the second shadow width; specifically, the compression ratio is calculated based on SR1=20*log10(S1/S2), as shown in Figure 2-3, where SR1 is the compression ratio, S1 is the first shadow width, and S2 is the second shadow width.

In some other implementations, a reference image is obtained, and the reference image is obtained by photographing a stationary target object by the camera module to be tested; then, the reference shadow width in the reference image is obtained, and the reference shadow width is the identification mark in the reference image. The width of the transition area to and from the image background. Finally, based on the first shadow width, the second shadow width and the reference, the compression ratio is obtained; that is, the compression ratio can be calculated based on SR2=20*log10((S1-S0)/(S2-S0)), as shown in Figure 2- 4, where SR2 is the compression ratio, S1 is the first shadow width, S2 is the second shadow width, and S0 is the reference shadow width.

To sum up, the anti-shake detection method provided in this embodiment is obtained by acquiring the first image collected by the camera module to be tested when the anti-shake module is turned off. The object is shaken according to the preset shaking data; and, obtaining the second image collected when the camera module to be tested turns on the anti-shaking module and receiving the shaking data, and the first image is obtained by collecting the static target object; based on the first image and the For 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 collected based on the shaking data, and a vibration table is not required to provide a vibration source for the camera module to be tested. Therefore, for the same type of camera module, the control jitter data does not need to change, 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.
