[0002] The current method of adjusting parameters in mobile phone cameras is mainly achieved through physical buttons on the phone and virtual buttons or virtual scroll wheels on the screen. For people who want to take pictures according to their own wishes and needs, it is often necessary to adjust the camera parameters (also known as shooting parameters) according to the actual scene. Therefore, it is necessary to frequently click or slide the screen to adjust the parameters. This method makes the operation cumbersome for users. Summary of the Invention

[0030] 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.

[0031] The terms "first," "second," etc., used in this application's specification are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged 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, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0032] The following description, in conjunction with the accompanying drawings, details the shooting parameter adjustment method, apparatus, and electronic device provided in this application through specific embodiments and application scenarios.

[0033] like Figure 1 As shown in the figure, this application provides a method for adjusting shooting parameters, executed by an electronic device. The electronic device includes a first camera, and the first camera is equipped with a teleconverter lens. The method includes:

[0034] Step 101: With the shooting preview interface displayed, obtain the user's grip position on the teleconverter lens;

[0035] Step 102: Adjust the shooting parameters and update the shooting preview interface according to the grip position.

[0036] It should be noted that, in this embodiment of the application, the user's grip position on the teleconverter lens is obtained while the shooting preview interface is displayed. Based on the grip position, the shooting parameters are adjusted and the shooting preview interface is updated. In this way, the shooting parameters can be adjusted by grip position, without the need for frequent clicking or swiping of the screen to adjust the shooting parameters. This makes it more convenient for users to operate and improves the photography experience of electronic devices.

[0037] Optionally, the shooting parameters mentioned in the embodiments of this application are set when the teleconverter is mounted; for example, a parameter is set by default when the user mounts the teleconverter, or the parameter can be set based on the user's selection.

[0038] Optionally, the shooting parameters mentioned in the embodiments of this application include, but are not limited to, one of the following:

[0039] Focus distance, zoom ratio, shooting brightness, and exposure time.

[0040] It should be noted that, generally speaking, only one shooting parameter can be adjusted at a time based on the grip position of the teleconverter. For example, during initial mounting, shooting parameter A can be set for adjustment; during subsequent mounting, shooting parameter B can be set for adjustment. Of course, in some embodiments, two or more shooting parameters can be adjusted simultaneously based on the grip position.

[0041] It should be noted that the application scenario of this application embodiment is that the electronic device includes at least two cameras, one is a first camera for mounting a teleconverter lens, and the other is a second camera responsible for capturing images from the teleconverter lens. For example, the first camera is a periscope camera, and the second camera is a main camera, a wide-angle camera, or other cameras other than a periscope camera.

[0042] Optionally, one possible application scenario in this application embodiment is: to achieve image acquisition in telephoto extension mode by mounting a teleconverter lens on the periscope camera.

[0043] For example, taking three commonly used cameras as an example, one option is to arrange the relative positions of the cameras as follows: Figure 2 As shown, Figure 2 A diagram showing the rear camera arrangement of electronic device 20 is provided. The three cameras are arranged in an L-shape. The camera in the upper left direction is a periscope camera 21, the camera in the lower left direction is the main camera 22, and the camera in the lower right direction is a wide-angle camera 23. In this case, the teleconverter lens is mounted on the periscope camera.

[0044] Furthermore,Figure 3 The diagram shows a comparison of an electronic device with and without a teleconverter lens. In the case of the electronic device 20 without a teleconverter lens, the three cameras on the back of the electronic device are clearly visible: the periscope camera 21, the main camera 22, and the wide-angle camera 23. After attaching the teleconverter lens, one can clearly see the teleconverter lens 30 (which is mounted on the original periscope camera 21) and the two original cameras on the electronic device: the main camera 22 and the wide-angle camera 23.

[0045] Optionally, in one implementation, before obtaining the user's grip position on the teleconverter lens, the method further includes:

[0046] Acquire the first image captured by the second camera of the electronic device;

[0047] If the first image contains an image area corresponding to a teleconverter lens, then it is determined that the first camera is equipped with a teleconverter lens.

[0048] It should be noted that in this case, image recognition is performed on the image captured by the second camera to determine whether there is a teleconverter in the image. If there is, the operation of obtaining the user's grip position on the teleconverter can continue. If there is no teleconverter, the operation of obtaining the user's grip position on the teleconverter does not need to be performed.

[0049] For example, with Figure 2 Taking the camera shown as an example, the above implementation method is illustrated as follows: In this case, the preview stream of the wide-angle camera is called to detect whether the electronic device is equipped with a teleconverter lens, such as... Figure 4 and Figure 5 The difference in wide-angle preview frames with and without a teleconverter is shown (it should be noted here that...). Figure 4 and Figure 5 The interface shown is a wide-angle preview stream, which is not displayed on the electronic device's camera interface. The camera interface displays the periscope camera's view in teleconverter mode. The reason for presenting the wide-angle camera interface here is primarily to explicitly showcase the wide-angle camera preview (for subsequent descriptions of the solution). Whether the electronic device is equipped with a teleconverter lens is clearly distinguished in the upper right corner of the wide-angle camera preview stream, such as... Figure 4 As shown, without a teleconverter, the image from the teleconverter will not be displayed in the upper right corner of the wide-angle camera's output frame 40, but... Figure 5As shown, when a teleconverter is mounted, the upper right corner of the frame output from the wide-angle camera 40 can display the image 41 captured by the teleconverter. Therefore, the process of determining whether a target lens exists in the first image in this embodiment is a typical image binary classification problem. The image is classified to detect whether a teleconverter exists in the upper right corner. If no teleconverter exists, the grip position detection stops, and the wide-angle camera is turned off. If a teleconverter exists, the user's grip position on the teleconverter is detected in real time. Further... Figure 6 and Figure 7 The image shown is a frame output from a wide-angle camera under different grip positions. Figure 6 It is held by the user at the outer end of the teleconverter lens (also known as the far end, i.e. the end away from the electronic device). Figure 7 It is held by the user at the inside of the teleconverter lens (also known as the near end, i.e. the end closest to the electronic device).

[0050] Optionally, in one implementation, the specific implementation of obtaining the user's grip position on the teleconverter lens includes:

[0051] Based on the first image captured by the second camera of the electronic device, the user's grip position on the teleconverter lens is determined.

[0052] In some embodiments, determining the user's grip position on the teleconverter lens based on the first image captured by the second camera of the electronic device includes:

[0053] Based on the first image, determine the location information of each contact point of the user;

[0054] Based on the location information, the user's grip position on the teleconverter lens is determined, and the grip position includes: gripping the first end of the teleconverter lens away from the electronic device, gripping the middle of the teleconverter lens, and gripping the second end of the teleconverter lens closer to the electronic device.

[0055] It should be noted that when determining the grip position, you can choose to detect every frame, every second, or any other arbitrary time interval, depending on the actual debugging situation.

[0056] Optionally, in one implementation, determining the location information of each user's contact point based on the first image includes:

[0057] A target image is extracted from the first image, and the target image is the image corresponding to the area where the teleconverter lens is located in the first image;

[0058] Based on the target image, determine the location information of each contact point of the user.

[0059] Alternatively, for example, with Figure 2 In terms of the camera distribution of electronic devices, the second lens is a wide-angle camera.

[0060] It should be noted that by first cropping the imaging area of ​​the teleconverter from the first image captured by the second camera, and then determining the holding position based on the cropped image of the teleconverter, the processing area of ​​the image can be reduced and the processing complexity can be lowered.

[0061] Optionally, in one implementation, the specific implementation of determining the location information of each user's contact point based on the target image includes:

[0062] Step 1011: Construct a target coordinate system based on the target image;

[0063] It should be noted that, in the embodiments of this application, after the target image is captured, the target image is usually a rectangular region. When constructing the target coordinate system, one vertex of the rectangular region is used as the origin of the coordinate system; for example, using... Figure 2 In terms of the camera distribution of electronic devices, the origin Po(0,0) in the target image is the vertex at the top left corner, the horizontal axis to the right is the positive X-axis, and the vertical axis downwards is the positive Y-axis.

[0064] Step 1012: Obtain the position coordinates of each user's contact point in the target coordinate system;

[0065] It should be noted that the contact point in the embodiments of this application can be understood as the touch point of the user's finger. Since the user may touch the target lens with multiple fingers at the same time, there will be multiple contact points in the target image. When obtaining the coordinate position, it is necessary to obtain the position coordinates of each contact point.

[0066] Optionally, in one implementation, the specific implementation of determining the user's grip position on the teleconverter lens based on the location information includes:

[0067] Step 1013: Determine the position coordinates of the contact point with the largest coordinate value in the first direction as the effective coordinates. The first direction is the direction in which the length of the target lens is projected onto the coordinate axis.

[0068] It should be noted that in this case, the coordinates of the contact point furthest from the origin are used as the basis for determining the grip position. For example, with... Figure 2 In terms of the camera distribution of electronic devices, the first direction is the X-axis direction.

[0069] Step 1014: Compare the effective coordinates with the target coordinates in the first direction to determine the user's grip position on the teleconverter lens;

[0070] Optionally, the first end of the teleconverter lens that is far from the electronic device can be understood as the far end of the teleconverter lens, the second end of the teleconverter lens that is close to the electronic device can be understood as the near end of the teleconverter lens, and the middle end of the teleconverter lens can be understood as the middle position of the teleconverter lens.

[0071] Optionally, the specific implementation of comparing the effective coordinates with the target coordinates in the first direction to determine the user's grip position includes one of the following:

[0072] A11. If Xh is less than a×Xm, then the holding position is determined to be holding the first end of the teleconverter lens;

[0073] Where Xh represents the effective coordinates of the gripping position, and Xm represents the target coordinates.

[0074] A12. If Xh is greater than or equal to a×Xm and less than or equal to b×Xm, then the holding position is determined to be holding the middle of the teleconverter lens;

[0075] A13. If Xh is greater than b×Xm, then the holding position is determined to be holding the second end of the teleconverter lens;

[0076] It should be noted that in the embodiments of this application, the values ​​of a and b are greater than 0 and less than 1, and a is less than b.

[0077] Optionally, the values ​​of a and b can be determined based on the actual debugging results. For example, a can be set to 1 / 3 and b to 2 / 3.

[0078] Optionally, a schematic diagram showing the actual grip position of the user's hand and the imaging position of the contact point in the target image is shown below. Figure 8 , Figure 9 and Figure 10 As shown, where, Figure 8 The grip position is at the far end of the teleconverter lens. Figure 9 The grip position is in the middle of the teleconverter lens. Figure 10 The grip position is near the teleconverter lens.

[0079] Optionally, in one implementation, when the shooting preview interface is the shooting preview interface corresponding to the first camera, the specific implementation of adjusting the shooting parameters according to the holding position includes:

[0080] Step 1021: Determine the adjustment rate or adjustment size of the shooting parameters corresponding to the first camera based on the grip position;

[0081] Optionally, in one implementation, the adjustment rate or adjustment magnitude of the shooting parameters corresponding to the first camera is determined based on the grip position, including at least one of B11-B13:

[0082] B11. If the holding position is the first end of the teleconverter lens, the shooting parameters are adjusted at a first rate or a first value.

[0083] For example, the first speed is determined as follows: First speed = a × Xm – Xh.

[0084] For example, the first value is determined as follows: First value = a × Xm – Xh.

[0085] Optionally, the first value refers to the magnitude of the parameter adjustment, such as increasing or decreasing the zoom magnification by a value when held at the far end.

[0086] B12. If the holding position is at the middle of the teleconverter lens, the shooting parameters are adjusted at the second rate or the second value.

[0087] It should be noted that when the user holds the teleconverter in the middle, the shooting parameters do not need to be adjusted. That is, in this case, the value of the second rate can be 0 or the value of the second value can be 0.

[0088] B13. If the holding position is the second end of the teleconverter lens, then adjust the shooting parameters at the third rate or the third value;

[0089] For example, the third rate is determined as follows: Third rate = Xh - b × Xm.

[0090] For example, the third value is determined as follows: Third value = Xh - b × Xm.

[0091] It should be noted that, under normal circumstances, the first rate, the second rate, and the third rate are different in magnitude, and the first value, the second value, and the third value are different in magnitude.

[0092] Step 1022: Adjust the shooting parameters according to the adjustment rate or the adjustment size;

[0093] Optionally, the specific implementation of adjusting the shooting parameters according to the adjustment rate or the adjustment magnitude includes:

[0094] The adjustment direction of the shooting parameters is determined based on the grip position, and the adjustment direction includes increasing the parameter value or decreasing the parameter value;

[0095] The shooting parameters are adjusted according to the adjustment direction and the adjustment rate or the adjustment size.

[0096] It's important to note that the grip position determines whether the parameter value is increased or decreased. For example, holding the teleconverter at the first end increases the parameter value, while holding it at the second end decreases it; conversely, holding it at the second end increases the parameter value, while holding it at the first end decreases it. Holding the teleconverter at the middle can be considered either an increase or decrease, because if the adjustment rate or adjustment value is set to 0, the parameter value will not change; that is, no adjustment will be made.

[0097] It should be noted that the adjustment rate can be multiplied by a coefficient as needed in actual use. The smaller the adjustment rate value, the slower the parameter adjustment; the larger the adjustment rate value, the faster the parameter adjustment. Similarly, the adjustment magnitude can be multiplied by a coefficient as needed in actual use. The smaller the adjustment magnitude value, the less the parameter changes; the larger the adjustment magnitude value, the more the parameter changes.

[0098] For example, to determine the adjustment rate, assume the segmented teleconverter region is 720 pixels high and 540 pixels wide. Then, with the top-left corner as the origin, the coordinates of the four corners of the image are: top-left corner P(0,0), bottom-left corner P(0,720), top-right corner P(540,0), and bottom-right corner P(540,720), and Xm = 540. Assume the parameters distinguishing between far, mid, and near ends are a = 1 / 3 and b = 2 / 3.

[0099] If the user's hand is holding the teleconverter at the far end, contact point detection is performed on the target image to obtain the position coordinates of each contact point. The position coordinate with the largest X-axis coordinate value is taken as the effective coordinate (i.e., the effective position coordinate used to determine the grip position). The effective coordinate is P(100, 600), that is, Xh = 100. Since Xh = 100, Xm = 540, and Xh < 1 / 3 × Xm, the grip position is determined to be holding the far end of the target lens. The adjustment rate = a × Xm – Xh, specifically 1 / 3 × 540 – 100 = 80. The adjustment rate can be normalized, 80 / 180 = 0.444. Assuming the base adjustment speed is 10 codes, then the adjustment speed of the grip position at this time is 0.444 × 10 = 4.44 codes.

[0100] If the user's hand is holding the teleconverter at the center, contact point detection is performed on the target image to obtain the position coordinates of each contact point. The position coordinate with the largest X-axis coordinate value is taken as the valid coordinate, which is P(220, 500), i.e., Xh = 220. Since Xh = 220, Xm = 540, and 1 / 3 × Xm < Xh < 2 / 3 × Xm, the holding position is determined to be holding the target lens at the center.

[0101] If the user's hand is holding the teleconverter near the lens, contact point detection is performed on the target image to obtain the position coordinates of each contact point. The position coordinate with the largest X-axis coordinate is taken as the effective coordinate, which is P(450, 450), i.e., Xh = 450. Since Xh = 450, Xm = 540, and 2 / 3 × Xm < Xh, the holding position is determined to be holding the target lens near the lens. The adjustment rate = Xh – b × Xm, specifically 450 – 2 / 3 × 540 = 90. The adjustment rate can be normalized, 90 / 180 = 0.5. Assuming the base adjustment speed is 10 codes, then the adjustment speed at this holding position is 0.5 × 10 = 5 codes.

[0102] The following is based on Figure 2 The distribution of cameras in electronic devices (electronic devices are mobile phones) is illustrated with specific examples of the implementation of this application embodiment.

[0103] Step S11: Install an external teleconverter lens on the mobile phone.

[0104] Step S12: Enter the telephoto zoom mode of the system camera. Figure 11 The image shown is a real-time preview displayed on the phone, with frames output from a periscope camera equipped with a teleconverter lens and displayed on the preview screen.

[0105] The specific technical implementation of this application is based on the frame output of a wide-angle camera. As mentioned above, the frame output of the wide-angle camera is not displayed on the screen; instead, the wide-angle preview stream is processed in the background to detect the user's grip position on the target lens in real time.

[0106] First, the preview stream from the wide-angle camera is accessed to check if the phone has a teleconverter lens attached. If no teleconverter lens is present, the grip position detection stops, and the wide-angle camera access is disabled. If a teleconverter lens is present, the user's grip position on the target lens is detected in real time.

[0107] Step S13: Based on the detected hand grip position, the algorithm determines whether the hand is gripping the near end, far end, or middle end of the teleconverter lens, thereby adjusting the shooting parameters of the mobile phone camera.

[0108] For example, if a user holds the phone with their left hand and the teleconverter with their right hand, then the hand holding the teleconverter in the target image will be the right hand.

[0109] For example, in an image captured by a wide-angle camera, the pixel positions of the teleconverter region are segmented and denoted as P(X,Y). The top-left corner is taken as the origin Po(0,0), the horizontal axis to the right is the positive X-axis, the vertical axis downwards is the positive Y-axis, and the bottom-right corner coordinates are Pm(Xm,Ym). Finger detection is performed on the image to obtain the coordinates Pi(X,Y) of each finger. The finger coordinate Ph(Xh,Yh) with the largest X-axis coordinate value is taken as the valid coordinate. The relationship between Xh and Xm is compared to determine the user's grip position on the target lens.

[0110] If Xh is less than a×Xm, then the holding position is determined to be holding the far end of the target lens, and the adjustment rate of the shooting parameters is a×Xm–Xh;

[0111] If Xh is greater than or equal to a×Xm and less than or equal to b×Xm, then the holding position is determined to be holding the middle of the target lens, and the adjustment rate of the shooting parameters is 0.

[0112] If Xh is greater than b×Xm, then the holding position is determined to be holding the near end of the target lens, and the adjustment rate of the shooting parameters is Xh-b×Xm.

[0113] For example, if the grip position is near the teleconverter, the shooting parameters are increased (or decreased) based on the adjustment rate; if the grip position is far from the teleconverter, the shooting parameters are decreased (or increased) based on the adjustment rate; if the grip position is in the middle of the teleconverter, the shooting parameters remain unchanged.

[0114] It should be noted that in this embodiment, the parameter size is adjusted in real time (depending on the actual debugging situation, the detection may be performed per frame, per second, or at any other arbitrary time interval) based on the holding position.

[0115] For example, taking adjusting the focus distance as an example, the specific process of this application embodiment includes:

[0116] Open the camera, enter the telephoto zoom mode scene, set the default parameter for holding the zoom lens to focus distance, and the default adjustment speed is 100code.

[0117] At this point, the focus distance after entering teleconverter mode is 4000 codes. If you need to focus at a closer distance, hold the teleconverter at the near end of the lens. Let's say the current position of holding the teleconverter at the near end is P(500, 450). The adjustment speed calculated from the above process is 78 codes. Therefore, we now increase the existing 4000 codes, and the focus distance becomes 4078 codes. Assuming the adjustment is done in seconds (this is an example, but the actual adjustment can be more precise to change the effect), the increase is 78 codes per second.

[0118] If the desired focusing distance has been reached, the user can hold the teleconverter in the middle area of ​​the lens or stop holding the teleconverter, and the focusing distance will not change further.

[0119] If you now need to focus at a greater distance, hold the teleconverter at the far end. Let's say you're currently holding the teleconverter at P(50, 620). The adjustment speed calculated from the above process is 72 codes. Therefore, decrease the current focus distance. Again, assuming the adjustment is done in seconds, decrease the focus distance by 72 codes per second. Once the desired focus distance is reached, hold the teleconverter in the middle area or remove it from your hand, keeping the focal length unchanged.

[0120] For example, taking adjusting the zoom level as an example, the specific process of this application embodiment includes:

[0121] Open the camera, enter the telephoto zoom mode, and set the default adjustment parameter for holding the telephoto lens to zoom magnification and the default adjustment speed to 20.

[0122] The default zoom level in teleconverter mode is 200. To zoom to a higher magnification, hold the teleconverter at the far end of the lens. Assuming the current position is P(100, 600), the calculated adjustment speed is 9. Therefore, increase the zoom level from 200. Again, assuming adjustments are made in seconds, the increase is 9 per second. Once the desired magnification is achieved, move your hand to the center of the teleconverter or remove the lens altogether, maintaining the same zoom level.

[0123] If you need to zoom to a smaller magnification, hold the teleconverter near the end of the lens. Let's say your current position is P(450, 500). The adjustment speed calculated from the above process is 10, so decrease the magnification. Again, assuming adjustments are made in seconds, decrease by 10 per second. Once you've reached the desired magnification, hold the teleconverter in the middle area or remove it entirely, keeping the magnification unchanged.

[0124] It should be noted that this application embodiment proposes a method for adjusting shooting parameters by holding the teleconverter lens in different positions. This allows for adjusting shooting parameters by holding the lens in different positions, without requiring physical buttons or screen contact, thus improving interactivity. Furthermore, this application embodiment can also adjust other parameters on the electronic device; that is, as long as the teleconverter lens is installed, other parameters can be adjusted by detecting the holding position.

[0125] The shooting parameter adjustment method provided in this application can be executed by a shooting parameter adjustment device. This application uses an example of a shooting parameter adjustment device executing the shooting parameter adjustment method to illustrate the shooting parameter adjustment device provided in this application.

[0126] like Figure 12 As shown, the shooting parameter adjustment device of this application is applied to an electronic device, which includes a first camera and a teleconverter lens, comprising:
