Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an aperture adjustment method and apparatus. Background Technology

[0002] Typically, the mechanical aperture in a camera is a device driven by mechanical gears. Due to problems such as gear meshing errors, misalignment, and loss of synchronization, poor image quality can result.

[0003] To address the aforementioned issues with mechanical apertures, the aperture value needs to be calibrated at the factory. Specifically, this typically involves arranging and combining the following calibration conditions: temperature, typical aperture value, different phone orientations, and aperture movement direction. By arranging and combining these calibration conditions, multiple calibration tables can be obtained. Using these calibration tables, the final aperture value can be obtained.

[0004] However, this method requires adding a calibration station to the production line, which increases production costs; moreover, the aperture value obtained under the above calibration conditions has low accuracy. Summary of the Invention

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The aperture adjustment method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] Please refer to Figure 1 This is a flowchart illustrating an aperture adjustment method provided in an embodiment of this application. This method can be applied to electronic devices, such as mobile phones, tablets, and laptops. (Refer to...) Figure 2 The electronic device includes a camera unit 20, which comprises a first camera 21, a second camera 22, and an image signal processor (ISP) 25. The image signal processor 25 is connected to both the first camera 21 and the second camera 22. The first camera 21 is a variable aperture camera, meaning its aperture value can change. The second camera 22 is a fixed aperture camera, meaning its aperture value cannot change. Figure 1 As shown, the method may include steps 1100 to 1300, which will be described in detail below.

[0029] Step 1100: When a change in the aperture value of the first camera of the electronic device is detected, the first parameter of the first camera and the second parameter of the second camera of the electronic device are obtained.

[0030] Optionally, the electronic device provides a first adjustment control for manually adjusting the aperture value of the first camera. The user can manually adjust the aperture value of the first camera by clicking the first adjustment control.

[0031] Optionally, the electronic device also includes a second adjustment control for automatically adjusting the aperture value of the first camera. The user can activate the automatic adjustment of the aperture value of the first camera by clicking the second adjustment control. Specifically, the electronic device will adjust the aperture value of the first camera accordingly, either widening or narrowing it, based on the illumination of the subject and feedback from the video signal.

[0032] It should be noted that if the aperture value of the first camera changes, the aperture value of the first camera needs to be adjusted to obtain the optimal aperture value of the first camera, replacing the aperture value fed back by the first camera itself.

[0033] Specifically, the electronic device monitors the aperture value of the first camera in real time. Whether the user manually adjusts the aperture value or the electronic device adjusts it automatically, the electronic device will detect a change in the aperture value. Upon detecting a change in the aperture value, the electronic device can activate the real-time calibration function. When the real-time calibration function is enabled, the electronic device can calibrate the aperture value of the first camera in real time.

[0034] The first parameters of the first camera include first shooting parameters and first brightness calibration parameters when the first camera captures the first image. The second parameters of the second camera include second shooting parameters and second brightness calibration parameters when the second camera captures the second image. Typically, the first camera captures the Nth frame of the first image when a change in the aperture value of the first camera is detected, and the second camera captures the Nth frame of the second image.

[0035] The first shooting parameters include a first exposure parameter and a first 3A statistical parameter, and the second shooting parameters include a second exposure parameter and a second 3A statistical parameter.

[0036] The first exposure parameter can include aperture value, shutter speed, and ISO (International Organization for Standardization). The second exposure parameter can also include aperture value, shutter speed, and ISO.

[0037] The first 3A statistical parameters can include autofocus (AF), auto exposure (AE), and auto white balance (AWB). The second 3A statistical parameters can also include autofocus (AF), auto exposure (AE), and auto white balance (AWB). Generally, the 3A statistical parameters can be referred to as the auto exposure (AE) statistical values.

[0038] The first brightness calibration parameter and the second brightness calibration parameter are pre-calibrated ISO data. For example, the first brightness calibration parameter could be the light sensitivity of the first camera 21 at a reference ISO of 100. Similarly, the second brightness calibration parameter could be the light sensitivity of the second camera 22 at a reference ISO of 100.

[0039] Specifically, when the first camera 21 captures the Nth frame of the first image fA(N) and the second camera 22 captures the Nth frame of the second image fB(N), if the electronic device detects a change in the aperture value of the first camera 21, the electronic device will capture both the Nth frame of the first image fA(N) captured by the first camera 21 and the Nth frame of the second image fB(N) captured by the second camera 22. The AE statistics module in the image signal processor processes the first image fA(N) and the second image fB(N) to obtain the aperture value FnumA(N), shutter speed ShuA(N), ISO sensitivity ISOA(N), and AE statistics value YA(N) when the first camera 21 captures the Nth frame of the first image fA(N). It also obtains the aperture value FnumB(N), shutter speed ShuB(N), ISO sensitivity ISOB(N), and AE statistics value YB(N) when the second camera 22 captures the Nth frame of the second image fB(N).

[0040] Step 1200: Determine the target aperture value of the first camera based on the first parameter and the second parameter.

[0041] Among them, the target aperture value of the first camera is the optimal aperture value of the first camera.

[0042] In this embodiment, step 1200, which determines the target aperture value of the first camera based on the first parameter and the second parameter, may further include the following steps 1210 to 1240:

[0043] Step 1210: Determine the first brightness value of the first camera in the public field of view area based on the first 3A statistical parameters.

[0044] The common field of view (FOV) is the area shared by the first camera and the second camera. It should be noted that the method for obtaining the common FOV of the first camera 21 and the second camera 22 is existing technology. For example, the common FOV of the first camera 21 and the second camera 22 can be obtained through image matching. Alternatively, it can be obtained through pre-calibration combined with actual distance measurement. Of course, other methods can also be used to obtain the common FOV of the first camera 21 and the second camera 22; this embodiment does not limit this method.

[0045] In step 1210, the electronic device can obtain the first brightness value lumaA(N) of the first camera 21 in the public field of view based on the AE statistical value YA(N) when the first camera 21 acquires the first image fA(N) in the Nth frame.

[0046] Step 1220: Determine the second brightness value of the second camera in the public field of view area based on the second 3A statistical parameters.

[0047] In step 1220, the electronic device can obtain the second brightness value lumaB(N) of the second camera 22 in the common field of view based on the AE statistical value YB(N) when the second camera 21 acquires the second image fB(N) in the Nth frame.

[0048] Step 1230: Determine the calibrated brightness deviation between the first camera and the second camera based on the first brightness calibration parameter and the second brightness calibration parameter.

[0049] In step 1230, the electronic device can obtain the calibration brightness deviation ratio1 between the first camera 21 and the second camera 22 based on the first brightness calibration parameter and the second brightness calibration parameter.

[0050] Step 1240: Determine the target aperture value of the first camera based on the first brightness value, the second brightness value, the calibrated brightness deviation, the first exposure parameter, and the second exposure parameter.

[0051] In this step 1240, the first brightness value lumaA(N) and the second brightness value lumaB(N) usually satisfy the following formula (1):

[0052]

[0053] Wherein, ShuA(N) represents the shutter speed when the first camera 21 captures the first image fA(N) in the Nth frame, ShuB(N) represents the shutter speed when the second camera 22 captures the second image fB(N) in the Nth frame, FnumB(N) represents the aperture value when the second camera 22 captures the second image fB(N) in the Nth frame, RealFnumA(N) represents the target aperture value of the first camera 21, ISOA(N) represents the ISO sensitivity when the first camera 21 captures the first image fA(N) in the Nth frame, ISOB(N) represents the ISO sensitivity when the second camera 22 captures the second image fB(N) in the Nth frame, ISO100(A) represents the reference ISO sensitivity of the first camera 21, and ISO100(B) represents the reference ISO sensitivity of the second camera 22.

[0054] Based on the above formula (1), the target aperture value when the first camera captures the first image in the Nth frame can be obtained:

[0055]

[0056] The ratio between the reference sensitivity ISO100 (A) of the first camera 21 and the reference sensitivity ISO100 (B) of the second camera 22 is the calibration brightness deviation ratio1.

[0057] Here, the electronic device can directly use the target aperture value RealFnumA(N) of the first camera when it captures the first image in the Nth frame as the target aperture value RealFnumA of the first camera.

[0058] Step 1300: Adjust the aperture value of the first camera to the target aperture value.

[0059] In this embodiment, after obtaining the target aperture value RealFnumA of the first camera, the electronic device can adjust the aperture value of the first camera to the target aperture value RealFnumA.

[0060] According to an embodiment of this application, when a change in the aperture value of the first camera of an electronic device is detected, the electronic device can acquire the first parameter of the first camera and the second parameter of the second camera of the electronic device, and determine the target aperture value of the first camera based on the first and second parameters, thereby adjusting the aperture value of the first camera to the target aperture value. This adjustment of the aperture value of the first camera by referring to the first parameter of the first camera and the second parameter of the second camera improves the adjustment accuracy of the aperture value of the first camera. Moreover, the user can automatically adjust the aperture value of the first camera in real time during the use of the electronic device, eliminating the need for calibration in the factory and reducing costs.

[0061] In one embodiment, step 1100 above, when a change in the aperture value of the first camera of the electronic device is detected, may further include: when a change in the aperture value of the first camera of the electronic device is detected, obtaining the first shooting parameters when the first camera continuously captures the i-th frame of the first image in K consecutive first images, and the second shooting parameters when the second camera continuously captures the i-th frame of the second image in K consecutive second images.

[0062] Where K is an integer greater than 1, and i is an integer from N to N+K-1. i can represent the sequence number of a first image captured by the first camera among all the first images captured. i can also represent the sequence number of a second image captured by the second camera among all the second images captured.

[0063] Specifically, when a change in the aperture value of the first camera is detected, the first camera captures the first image in the Nth frame, and the second camera captures the second image in the Nth frame.

[0064] Specifically, when the first camera 21 captures the Nth frame first image fA(N) and the second camera 22 captures the Nth frame second image fB(N), if the electronic device detects a change in the aperture value of the first camera 21, the first camera can continuously capture K frames of the first image. For each frame in the K frames, such as the Nth frame, the electronic device will capture the Nth frame first image fA(N) captured by the first camera 21 and the Nth frame second image fB(N) captured by the second camera 22. The AE statistics module in the image signal processor processes the first image fA(N) and the second image fB(N) respectively to obtain the aperture value FnumA(N), shutter speed ShuA(N), ISOA(N), and AE statistics value YA(N) when the first camera 21 captures the Nth frame first image fA(N). It also obtains the aperture value FnumB(N), shutter speed ShuB(N), ISOB(N), and AE statistics value YB(N) when the second camera 22 captures the Nth frame second image fB(N).

[0065] Through this embodiment, the first shooting parameters when the first camera 21 captures each frame of the first image in K frames of the first image, and the second shooting parameters when the second camera 22 captures each frame of the second image in K frames of the second image can be obtained.

[0066] Here, step 1200 above, which determines the target aperture value of the first camera based on the first parameter and the second parameter, may further include: determining the target aperture value of the first camera when acquiring the first image in the i-th frame based on the first brightness calibration parameter, the second brightness calibration parameter, the first shooting parameter corresponding to the i-th frame of the first image in K frames of the first image, and the second shooting parameter corresponding to the i-th frame of the second image in K frames of the second image; and determining the target aperture value of the first camera based on the target aperture value of each frame of the first image in K frames of the first image.

[0067] In this embodiment, for the i-th frame in the K consecutively acquired frames, the electronic device uses the above steps 1210 to 1240 to calculate the target aperture value RealFnumA(i) when the first camera acquires the first image of the i-th frame, thus obtaining K target aperture values ​​RealFnumA(i). The target aperture value RealFnumA of the first camera satisfies the following formula (3):

[0068]

[0069] Where i takes the value of an integer from N to N+K-1, RealFnumA(i) represents the target aperture value when the first camera captures the first image in the first frame of K frames, and W(o) represents the weight of the target aperture value RealFnumA(i) when the first camera 21 captures the first image in the first frame. The larger W(i) is, the greater the influence of the corresponding target aperture value RealFnumA(i) on RealFnumA.

[0070] In this embodiment, after obtaining the target aperture value RealFnumA of the first camera 21, the electronic device can adjust the aperture value of the first camera to the target aperture value RealFnumA.

[0071] According to this embodiment, the final target aperture value of the first camera is determined based on the target aperture values ​​corresponding to the K frames of the first image captured by the first camera, which is more accurate.

[0072] In one embodiment, the electronic device may include multiple second cameras, as referenced. Figure 3 The camera device 20 includes a first camera 21, a second camera 22, a second camera 23, a second camera 24, and an image signal processor 25. The image signal processor 25 is connected to the first camera 21, the second camera 22, and the second camera 23, respectively.

[0073] Here, step 1100 above, which obtains the first parameter of the first camera and the second parameter of the second camera of the electronic device, may further include: obtaining the first parameter of the first camera and the second parameters corresponding to the multiple second cameras of the electronic device.

[0074] Reference Figure 3 The electronic device will acquire the first shooting parameters when the first camera 21 captures the first image, the second shooting parameters when the second camera 22 captures the second image, the second shooting parameters when the second camera 23 captures the second image, and the second shooting parameters when the second camera 24 captures the second image. It will also acquire the first brightness calibration parameters corresponding to the first camera 21, the second brightness calibration parameters corresponding to the second camera 22, the second brightness calibration parameters corresponding to the second camera 23, and the second brightness calibration parameters corresponding to the second camera 24.

[0075] Here, step 1200 above, which determines the target aperture value of the first camera based on the first parameter and the second parameter, may further include: determining the target aperture value of the first camera corresponding to each second camera based on the first parameter and the second parameter corresponding to each second camera; and determining the target aperture value of the first camera based on the target aperture value of the first camera corresponding to each second camera.

[0076] Continuing with the example above, the electronic device will obtain the target aperture value of the first camera 21 calibrated by the second camera 22 based on the first shooting parameters when the first camera 21 captures the first image, the first brightness calibration parameters of the first camera 21, the second shooting parameters when the second camera 22 captures the second image, and the second brightness calibration parameters of the second camera 22.

[0077] Furthermore, based on the first shooting parameters when the first camera 21 captures the first image, the first brightness calibration parameters of the first camera 21, the second shooting parameters when the second camera 23 captures the second image, and the second brightness calibration parameters of the second camera 23, the target aperture value of the first camera 21 calibrated by the second camera 23 is obtained.

[0078] Furthermore, based on the first shooting parameters when the first camera 21 captures the first image, the first brightness calibration parameters of the first camera 21, the second shooting parameters when the second camera 24 captures the second image, and the second brightness calibration parameters of the second camera 24, the target aperture value of the first camera 21 calibrated by the second camera 24 is obtained.

[0079] At the same time, the electronic device can perform weighted processing on the target aperture value of the first camera 21 calibrated by the second camera 22, the target aperture value of the first camera 21 calibrated by the second camera 23, and the target aperture value of the first camera 21 calibrated by the second camera 24 to obtain the target aperture value of the first camera 21.

[0080] According to this embodiment, the aperture value of the first camera is calibrated based on multiple second cameras, resulting in higher accuracy.

[0092] Where K is an integer greater than 1, and i is an integer from N to N+K-1;

[0093] Specifically, when a change in the aperture value of the first camera is detected, the first camera captures the first image in the Nth frame, and the second camera captures the second image in the Nth frame.

[0094] In one embodiment, the first parameter of the first camera further includes a first brightness calibration parameter of the first camera, and the second parameter of the second camera further includes a second brightness calibration parameter of the second camera.
