Detailed Description
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 to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The embodiment of the invention provides an anti-shake detection method which can be used for detecting the anti-shake performance of an OIS anti-shake module of a camera module, does not need to use a shaking table to provide a shaking environment for the camera module in the detection process, can ensure higher detection consistency and has low cost. The method of the embodiments of the present invention will be illustrated and described in detail below by specific examples.
Referring to fig. 1, in an embodiment of the present invention, an anti-shake detection method is provided, including:
step S10: when the anti-shake module of the camera module to be tested is closed, shooting a target object in a preset picture plate video to obtain a first image; dithering the target object in the picture board video according to preset dithering data;
step S20: when the anti-shake module of the camera module to be tested is started, receiving the shake data, and shooting a target object in the picture board video shooting to obtain a second image;
step S30: obtaining the compression ratio of the camera module to be tested based on the first image and the second image; the compression ratio is used for verifying the anti-shake performance of the camera module to be tested.
In the present embodiment, in steps S10-S30, the first image is acquired by acquiring the camera module to be tested when the anti-shake module is turned off (i.e., the OIS module is turned off), and the first image is acquired by acquiring a shake-acquired target object. Because the anti-shake function of the camera module to be tested is closed at this time, the first image at this time can be acquired by collecting the static target object when the camera module to be tested shakes according to the shake data. At the moment, the vibration source provided by the vibration table for the camera module to be tested is avoided. Then, starting the anti-shake function of the camera module to be tested, and directly inputting shake data to the camera module to be tested, wherein the camera module to be tested is equivalent to obtain shake data collected by a gyroscope; at the moment, the driving chip of the camera module to be detected recognizes that the camera module to be detected is in a shaking state according with shaking data, and anti-shaking compensation is carried out on the current shaking state; therefore, at this time, it is equivalent to that the camera module to be tested acquires the jittered target object to obtain the second image when the anti-shake compensation is started in the jittering state. Therefore, the state that the camera module shoots a static target object in a shaking state and when the anti-shaking module is started is simulated, and the use of a shaking table is also avoided. And finally, based on the first image and the second image, the compression ratio of the camera module to be detected can be determined, so that the anti-shake performance detection of the camera module to be detected is realized. A specific possible implementation of each step of the method is described below.
Step S10: when the anti-shake module of the camera module to be tested is closed, shooting a target object in a preset picture plate video to obtain a first image; and the target object in the picture plate video shakes according to preset shaking data.
In step S10, the camera module to be measured includes an OIS module, and the anti-shake module is turned off, that is, the OIS module is turned off. The jitter angle corresponding to the jitter data meets the test condition for testing the camera module to be tested, namely the jitter angle corresponding to the jitter data is the same as the jitter angle when the standard shaking table is adopted to test the camera module to be tested.
In this embodiment, the target object is a test chart played by using a preset chart video, and is referred to as a chart in the technical field; for example, the chart board may be fixed to a vibration source for vibration, and the recording tool may be used to record the test chart board to obtain the chart board video. Then, the picture board video is photographed and collected to obtain a first image, as shown in fig. 2. The method comprises the following specific steps:
firstly, a preset test chart is dithered according to dithering data. For example, the test chart board may be fixed on a vibration table after standard verification, and then the vibration table is controlled to vibrate according to a vibration angle curve corresponding to the vibration data. Then, recording a test chart under a jitter state to obtain a chart video; the picture video may be a target object. During recording, high frame rate recording can be adopted to realize better simulation effect; e.g., 120 frames, 175 frames, 240 frames, etc. The mode only needs to use the shaking table once and only needs to calibrate the shaking table once at most for the camera module under the same type of test condition. The obtained picture plate video can be used as a target object repeatedly, so that the hardware cost and the time cost are greatly reduced, and the detection efficiency is improved.
The adopted test chart board can be a cross chart or a circular point chart, and the line width or the shadow width in the obtained first image and the second image can be ensured to be accurately determined. In this embodiment, a cross-shaped drawing is used as an example for description. In addition, other test pattern boards with identification mark patterns can be used without limitation. When the camera module to be tested which does not start the anti-shake module shoots the identification mark in the shake state, a first image with the identification mark shadow can be obtained.
Step S20: and when the anti-shake module of the camera module to be tested is started, receiving the shake data, shooting the target object in the picture board video shooting, and obtaining a second image.
In step S20, a preset processor may be used to simulate the generation of the shaking data and output the shaking data to the camera module to be tested. Specifically, the anti-shake function of the camera module to be tested is started, and shake data generated by simulating of the preset processor is output to the camera module to be tested. For example, a Micro Controller Unit (MCU) may be used to simulate and generate the jitter data according to a preset program, where the jitter data may be output as the angle data obtained by integrating operation
Can guarantee like this that the driver chip of the module of making a video recording that awaits measuring can read discernment, need not to carry out secondary calculation, improve efficiency of software testing and degree of accuracy. And then, after receiving the angle data, controlling the camera module to be tested to shoot the target object to obtain a second image. At this time, the camera module to be tested receives the shake data, recognizes the state of the camera module to be tested as a shake state, and the anti-shake module performs shake compensation on the target object based on the shake data, so as to obtain a second image after the shake compensation, as shown in fig. 3.
Step S30: obtaining the compression ratio of the camera module to be tested based on the first image and the second image; the compression ratio is used for verifying the anti-shake performance of the camera module to be tested.
One implementation in step S30 may be as follows: determining 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 a transition region between the identification mark in the first image and the image background; the second shadow width is the width of the transition region between the identification mark in the second image and the background of the image. The image background refers to an image area other than the identification mark. Finally, obtaining a compression ratio based on the first shadow width and the second shadow width; specifically, the compression ratio is calculated based on SR1 ═ 20 × 1og10(S1/S2), as shown in fig. 2-3, where SR1 is the compression ratio, S1 is the first shaded width, and S2 is the second shaded width.
In other implementations, it may also be: acquiring a reference image, wherein the reference image is obtained by shooting a static target object by a camera module to be tested; then, a reference shadow width in the reference image is obtained, wherein the reference shadow width is the width of a transition region between the identification mark in the reference image and the image background. Finally, obtaining a compression ratio based on the first shadow width, the second shadow width and the reference; that is, the compression ratio may be calculated based on SR2 ═ 20 × 1og10((S1-S0)/(S2-S0)), as shown in fig. 2-4, where SR2 is the compression ratio, S1 is the first shaded width, S2 is the second shaded width, and S0 is the reference shaded width.
In summary, in the anti-shake detection method provided in this embodiment, a first image acquired by the camera module to be detected when the anti-shake module is turned off is acquired, the first image is acquired for acquiring a target object to be shaken, and the target object is shaken according to preset shaking data; acquiring a second image acquired when the camera module to be tested starts the anti-shake module and receives shake data, wherein the first image is acquired by acquiring a static target object; and obtaining the compression ratio of the camera module to be tested based on the first image and the second image, wherein the compression ratio is used for verifying the anti-shake performance of the camera module to be tested. In the whole method executing process, the first image and the second image are acquired based on the shaking data, and a shaking table is not needed for providing a shaking source for the camera module to be detected. Therefore, for the camera module with the same requirement, the control jitter data is not changed, the vibration table is not required to be tested and calibrated, the hardware cost and the time cost are greatly reduced, and the detection efficiency is improved.
