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.
Referring to fig. 1, a flowchart of an anti-shake detection method according to a first embodiment of the invention is shown; the anti-shake detection method comprises the following steps:
step S10: according to the vibration simulation signal, the gyro gain coefficient of the camera module and the reference coordinate of the image of the camera module, obtaining the anti-shake amplitude of the camera module in an anti-shake starting state; the vibration simulation signal is a signal that the standard vibration table vibrates according to a preset target vibration angle;
step S20: obtaining the compression ratio of the camera module according to the anti-shake amplitude and a preset target vibration angle; the compression ratio is used for verifying the anti-shake performance of the camera module.
The anti-shake detection method in this embodiment is applied to the OIS detection of the camera module, and may be executed in a Driver IC (Driver IC) of the camera module, or may be provided with a hardware module for execution separately. The method changes the conventional detection mode, vibration detection is not carried out by using a vibration table in the whole detection process, and anti-vibration response is carried out on the tested camera module on the basis of vibration simulation signals collected by a standard vibration table in advance to obtain anti-vibration amplitude; and finally, determining the compression ratio based on the anti-shake amplitude and the target shake angle. Therefore, the height consistency of the detection foundation can be ensured in the whole detection process, and the problem of detection errors caused by the difference of the vibration tables can be eliminated. Specific examples of each step of this example are set forth and described in detail below.
Step S10: according to the vibration simulation signal, the gyro gain coefficient of the camera module and the reference coordinate of the image of the camera module, obtaining the anti-shake amplitude of the camera module in an anti-shake starting state; the vibration simulation signal is a signal of the standard vibration table vibrating according to a preset target vibration angle.
In step S10, the vibration simulation signal is a vibration waveform obtained by performing vibration detection on the standard vibration stage by using a preset detection unit and vibrating according to a standard vibration angle and a standard frequency used in the test of the camera module to be tested. The detection unit can detect at least vibration waveforms of the standard vibration table in two directions of an X axis and a Y axis, as shown in FIG. 2; fig. 2 shows a vibration waveform detected by the detection unit when the standard vibration table vibrates at a standard frequency of 4HZ and a standard vibration angle of 1 °. The X-axis and the Y-axis are two vibration directions on the standard vibration table, and can be defined based on the actual vibration direction of the vibration table. The standard shaking table represents a shaking table with qualified shaking errors, correction is not needed, and all parameters are optimal or nearly optimal.
The detection unit may be a standard gyroscope or a hall sensor capable of detecting a vibration signal, without limitation. The vibration analog signal detected by the detection unit can be stored in a memory and is sent to a driving chip of the camera module through a signal transmitter when the vibration analog signal is required to be used.
A Gyro Gain coefficient (Gyro Gain) which is a compensation coefficient for inducing external shake by the gyroscope and preventing the IC drive motor from shaking reversely; and the code value is used for converting the shaking angle into the code value of the motor which needs response compensation after the camera shooting module sends the shaking. After the motor compensates the shaking angle, the imaging of the final camera module is ensured to be not fuzzy as far as possible.
The reference coordinates are one or more selected coordinates after the camera module shoots a test chart (chart) or other images for testing, and can be used as a reference basis after the camera module shakes to identify the offset of the response shake analog signal of the camera module and the gyro gain coefficient, namely the anti-shake amplitude. The test chart in this embodiment may be a commonly used black cross chart. Furthermore, the position of the reference coordinate is not limited, the center coordinate of the imaging of the camera module can be optimized in the embodiment, the influence of factors such as imaging distortion of the camera module is avoided, and the testing accuracy is improved.
One specific implementation of obtaining the anti-shake amplitude can be referred to as follows:
firstly, a gyro gain coefficient can be loaded, and an offset coordinate is obtained according to a vibration simulation signal; the offset coordinate is a coordinate corresponding to a reference coordinate after compensation based on a gyro gain coefficient; then, the anti-shake amplitude is obtained from the reference coordinates and the offset coordinates. Specifically, after the gyro gain coefficient is loaded on the driving chip, the driving chip can respond to the vibration analog signal transmitted by the signal transmitter to generate an adjusting signal for a lens part of the camera module; the motor of the camera module can control the lens part of the camera module to act based on the adjusting signal. At the moment, the camera module is not installed on the vibration table and only carries out response adjustment based on the vibration simulation signal; therefore, the camera module re-images the reference coordinate after responding to the vibration simulation signal, so that the offset coordinate is obtained. Because the imaging distance is known, the anti-shake amplitude can be determined according to the reference coordinate and the offset coordinate, and the amplitude is the amplitude generated by compensating the shake analog signal based on the gyro gain coefficient after the camera module starts the OIS.
Step S20: obtaining the compression ratio of the camera module according to the anti-shake amplitude and a preset target vibration angle; the compression ratio is used for verifying the anti-shake performance of the camera module.
In step S20, the target vibration angle is an upper limit of an angle at which the camera module vibrates when the OIS test is performed on the camera module, that is, a maximum angle, and it can be understood that the target vibration angle is an upper limit of the requirement of the anti-shake performance of the camera module. In this embodiment, at least two implementation manners are provided for step S20:
1. a compression ratio is determined based on the amplitude. The method comprises the following specific steps:
first, a target amplitude is obtained according to a target vibration angle. Because 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, as shown in FIG. 3.
Then, the compression ratio of the camera module is obtained according to the anti-shake amplitude and the target amplitude. In particular, it can be based on a formula
Obtaining a compression ratio; wherein SR is a compression ratio, B is an anti-shake amplitude, and T is a target amplitude; the better the anti-shake performance of the camera module, the closer the anti-shake amplitude and the target amplitude are, and therefore, the compression ratio calculation mode which can replace the existing scheme is adopted.
Through above-mentioned processing procedure, can adopt anti-shake amplitude and target amplitude to confirm the compression ratio, need not through the installation that will make a video recording the module reality and shoot the test on shaking the platform, avoided shaking the precision difference of platform to lead to the test result error to appear. Furthermore, the test is performed based on the method of the embodiment, the camera does not need to be installed on the shaking table, the static line width of the camera module in the static state does not need to be obtained, and the shaking table does not need to be started to obtain the line widths of the started OIS and the non-started OIS of the camera module. Therefore, the anti-shake test method of the embodiment also saves the process steps.
2. The compression ratio is determined based on the shock angle. The method comprises the following specific steps:
firstly, an anti-shake vibration angle is obtained according to the anti-shake amplitude. Because 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 angle, and the principle shown in fig. 3 can be referred to as such, and then the anti-shake angle can be determined by the inverse trigonometric function.
And then, obtaining the compression ratio of the camera module according to the anti-shake vibration angle and the target vibration angle. In particular, it can be based on a formula
Obtaining a compression ratio; wherein SR is a compression ratio, B 'is an anti-shake vibration angle, and T' is a 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, so that the compression ratio calculation mode which can replace the existing scheme is adopted.
Finally, the optical anti-shake effect of the camera module can be judged based on the obtained compression ratio, and the larger the compression ratio is, the better the optical anti-shake effect is. Can set up the compression ratio threshold value according to the demand, come the screening to satisfy the module of making a video recording of requirement, the compression ratio is greater than the module of making a video recording of compression ratio threshold value and is qualified module of making a video recording promptly.
Further, the method can be preferably implemented in the embodiment by the foregoing method 1; in the actual test process, the target vibration angle is generally 1-2 degrees, and the corresponding anti-shake vibration angle is also close to the value range of the target vibration angle; therefore, a large error may be generated when the inverse trigonometric function processing and the logarithm processing are performed. Therefore, in this embodiment, the error can be further reduced and the test accuracy can be improved by adopting the above-mentioned method 1.
In summary, in the anti-shake detection method provided in this embodiment, the anti-shake amplitude of the camera module in the anti-shake on state is obtained according to the shake analog signal, the gyro gain coefficient of the camera module, and the reference coordinate of the image formed by the camera module; the vibration simulation signal is a signal that the standard vibration table vibrates according to a preset target vibration angle; then, obtaining the compression ratio of the camera module according to the anti-shake amplitude and a preset target vibration angle; this compression ratio is used for verifying the anti-shake performance of the module of making a video recording. Therefore, when the method is used for carrying out anti-shake detection on the camera module, the method does not depend on the vibration table, avoids the precision difference among different vibration tables and improves the detection precision; meanwhile, the detection cost is also saved.
