[0018] FIG. 1 is a schematic diagram of the procedure of the camera shake prevention method provided in the embodiment of the present application, which includes step 201 and step 202.

[0019] In step 201, the electronic device No. 1 Camera first image In the case where the electronic device collects the hand-shake parameters in real time, the electronic device obtains the hand-shake parameters of the electronic device.

[0020] The camera shake parameter is intended to indicate the degree of camera shake of the electronic device.

[0021] In the embodiment of the present application, the camera may be a main camera, a wide-angle camera, or a long-focus camera, and the embodiment of the present application is not limited thereto.

[0022] In the embodiment of the present application, image was collected by the front camera of an electronic device. image may be collected by a rear camera of an electronic device. image may be collected by an external camera of an electronic device. image However, the embodiments of the present application are not limited thereto.

[0023] In the embodiment of the present application, image may include a target object, which may include at least one of a person and a landscape.

[0024] In the embodiment of the present application, the camera shake parameters and the camera shake degree of the electronic device may have a positive correlation or a negative correlation, and the embodiment of the present application is not limited thereto.

[0025] Optionally, in an embodiment of the present application, the hand shaking parameters include at least one of a rotation angle of the electronic device, a rotation angular velocity of the electronic device, a rotation direction of the electronic device, a movement speed of the electronic device, a movement acceleration of the electronic device, and a movement direction of the electronic device.

[0026] For example, the rotation angle of the electronic device may be any angle, the rotation angular velocity of the electronic device may be any angular velocity, and the rotation direction of the electronic device may be any direction.

[0027] It should be noted that the hand shake parameters include, but are not limited to, the above six types of parameters. For example, the hand shake parameters may be the rotation arc length of the electronic device calculated from the rotation angular velocity of the electronic device, or the displacement obtained by the electronic device from the moving speed.

[0028] In one example, when the shaking parameter is a rotation angle, the rotation angle and the shaking degree of the electronic device may have a positive correlation, i.e., the larger the rotation angle, the more severe the shaking degree of the electronic device, and the smaller the rotation angle, the less severe the shaking degree of the electronic device.

[0029] It should be mentioned that the rotation angle of the electronic device, the rotation angular velocity of the electronic device and the rotation direction of the electronic device can be obtained by a gyroscope.

[0030] In step 202, the electronic device calculates a first trimming parameter based on a first trimming parameter corresponding to the camera shake parameter. image The first area in the image is cropped, and the first area after cropping is image Display.

[0031] No. 1 image includes a first region and a second region, the second region being a first image and N frame image and the common area of ​​the Nth frame. image is the first image collected before collecting image where N is an integer equal to or greater than 1.

[0032] The first region is a first image It is understood that the other regions are those excluding the second region therein.

[0033] In the embodiment of the present application, the trimming parameters in the embodiment of the present application may be a trimming percentage, or a trimming dimension (eg, a trimming length and width, etc.), and the embodiment of the present application is not limited thereto.

[0034] In one example, the first trimming parameter is a trimming percentage, and the trimming percentage is a first image The area to be cropped and the first image It may be a percentage of the whole, and the first part after trimming image and No. 1 image It may be a percentage of the whole, and the examples of this application are not limited thereto.

[0035] In another example, the first cropping parameter is a cropping dimension, and the cropping dimension is a first image may be the dimensions of the area to be trimmed, and the first image However, the embodiment of the present application is not limited thereto.

[0036] For example, the electronic device may determine the camera shake parameters and then determine the first trimming parameters based on the correspondence between the camera shake parameters and the trimming parameters.

[0037] The correspondence between the camera shake parameters and the trimming parameters may be set by a system default value or may be preset by a user, and the embodiment of the present application is not limited thereto.

[0038] In one example, when the hand shake parameter is a rotation angle of an electronic device, the section value of the rotation angle of the electronic device may correspond to one trimming parameter. For example, when the rotation angle of the electronic device is a section value of 1 degree to 10 degrees, the corresponding trimming parameter may be 20%, and when the rotation angle of the electronic device is a section value of 11 degrees to 20 degrees, the corresponding trimming parameter may be 25%.

[0039] Exemplarily, the electronic device includes a first image and previous image The first one is to get the common area with image And electronic devices are number one image of N frames collected before collecting image It is also possible to compare the above.

[0040] Exemplarily, the first image Previous image Electronics are number one image At least one frame collected before image For example, the first image Previous image Electronics are number one image One frame collected before collecting image The electronic device may be a first image Five frames collected before collecting image may be also possible.

[0041] Exemplarily, the electronic device is a first image The step of trimming the first region may include the step of the electronic device trimming all or a portion of the first region.

[0042] It should be noted that the electronics performs the first trimming based on the first trimming parameter. image When trimming, first imageIf the second region in the second region is to be trimmed, the electronics may trim the second region.

[0043] It should be noted that in practice, the first frame collected by the electronics image The electronics does not need to do any processing and simply calculates the first frame's image However, the embodiment of the present application is not limited to this.

[0044] For example, if a user uses an electronic device to take a video, the electronic device may capture the first frame of image When the image was acquired, the electronics used the default cropping parameters of 20% to crop the first frame. image Trim the image and crop it. image After that, the user may continue to use the electronic device to take a second frame. image (That is, the above No. 1 image When the electronic device determines that the electronic device has rotated 10 degrees (i.e., detects the occurrence of a slight camera shake in the electronic device), the electronic device may determine the trimming parameter to be 20% based on the camera shake parameter. Next, the electronic device may set the trimming parameter to 20% and the first frame image Based on the second frame image In this case, as shown in FIG. 2, the electronic device may trim the second frame. image 31 may be displayed. After that, the user continues to take pictures using the electronic device and displays the third frame. image (That is, the above No. 1 image ) is collected, if the electronic device determines that the electronic device has rotated 30 degrees (i.e., detects the occurrence of strong camera shake in the electronic device), the electronic device may determine the trimming parameter to be 30% based on the camera shake parameter. Next, the electronic device may set the trimming parameter to 30% and the image Based on the third frame, image In this case, as shown in FIG. 3, the electronic device may trim the third frame. imageYou may also display 32.

[0045] In the method for preventing camera shake provided in the embodiment of the present application, first, No. 1 Camera first image When collecting the camera shake parameters in real time, the electronic device can obtain the camera shake parameters of the electronic device. Then, the electronic device calculates a first trimming parameter according to the first trimming parameter corresponding to the camera shake parameters. image The first area in the image is cropped, and the first area after cropping is image It is possible to display the first image includes a first region and a second region, the second region being a first image and N frame image and the common area of ​​the Nth frame. image is the first image collected before collecting image With a certain trimming parameter, image Compared with the conventional solution of trimming the first image, the above solution allows the electronic device to flexibly obtain different trimming parameters according to the degree of camera shake, and then trim the first image according to the different trimming parameters. image The area excluding the common area therebetween can be trimmed, thereby realizing the purpose of anti-shake of the electronic device and improving the flexibility of anti-shake of the electronic device.

[0046] Optionally, in the present embodiment, if the trimming parameters become too large, the trimmed image The visible range of the electronic equipment may be affected, making it impossible to meet the requirements for photography. image Based on preset cropping parameters to ensure a visible range of image may be trimmed.

[0047] For example, in step 202, a first trimming parameter is calculated based on the first trimming parameter corresponding to the camera shake parameter. image The step of trimming the first region in may specifically include the following step 202a.

[0048] In step 202a, the electronic device adjusts the first trimming parameter based on the first preset trimming parameter when the first trimming parameter is greater than the first preset trimming parameter. image Crop the first region in.

[0049] Exemplarily, the first preset trimming parameters may be configured by the system as defaults, or may be preset by a user, and the embodiment of the present application is not limited thereto.

[0050] Exemplarily, the first preset trimming parameter may be called a maximum trimming parameter.

[0051] It should be noted that for different cameras, the first preset cropping parameters may be the same or different, and the embodiment of the present application is not limited thereto.

[0052] For example, if the camera is a long focus camera, the first preset cropping parameter may be 25%, if the camera is a main camera, the first preset cropping parameter may be 40%, and if the camera is a wide angle camera, the first preset cropping parameter may be 50%.

[0053] It should be noted that if the trimming parameters are too large, the trimmed image Valid in image By having too little content, image The point is that the visible range of the light is affected.

[0054] The method for preventing camera shake provided in this application is image The electronic device may be applied to a scene in which a first preset trimming parameter is set, and a first image trimmed based on the first preset trimming parameter is output. imagecan be in the normal visible range, so if the first trimming parameter is greater than the first preset trimming parameter, the electronic device image The first preset trimming parameter is used to ensure a visible range of image may be trimmed.

[0055] Optionally, in an embodiment of the present application, when the electronic device has at least two cameras, the electronic device may further include: image The images were collected by a single camera to ensure a wide viewing range and further improve the anti-shake effect of electronic devices. image Another camera image may be replaced.

[0056] For example, when the electronic device includes a first camera and a second camera, the first trimming parameter is determined based on the first trimming parameter corresponding to the camera shake parameter in step 202. image The step of trimming the first region in may specifically include the following step 202b.

[0057] In step 202b, the electronic device is collected by a second camera. image and when the second trimming parameter is greater than the second preset trimming parameter, the electronic device determines a first trimming parameter based on the first trimming parameter. image Crop the first region in.

[0058] The first camera and the second camera are for collecting images of the same object, and the first image collected by the first camera is image The corresponding viewing angle is the second one collected by the second camera. image the second trimming parameter is a trimming parameter determined based on the camera shake parameter and corresponding to the second camera, and the first trimming parameter is a trimming parameter corresponding to the first camera.

[0059] The first image collected by the first camera imageThe corresponding viewing angle is the second one collected by the second camera. image The viewing angle is larger than the viewing angle corresponding to the first image of image The contents are the second image of image It is understood that there is more to it than content.

[0060] For example, when the second camera is a long-focus camera, the first camera may be a main camera or a wide-angle camera, and when the second camera is a main camera, the first camera may be a wide-angle camera, which can be specifically set according to actual requirements, and the embodiments of the present application are not limited thereto.

[0061] Exemplarily, the first cropping parameter being a cropping parameter corresponding to the first camera may include the first cropping parameter being a cropping parameter corresponding to the first camera determined based on the second cropping parameter, or the first cropping parameter being a cropping parameter corresponding to the first camera determined based on a camera shake parameter.

[0062] It should be noted that the first cropping parameter determined based on the second cropping parameter and the first cropping parameter determined based on the camera shake parameter may be the same or different, and the embodiment of the present application is not limited thereto.

[0063] In one example, the preset cropping parameters corresponding to the first camera and the preset cropping parameters corresponding to the second camera (ie, the second preset cropping parameters) may be different.

[0064] For example, the electronic device has a main camera and a wide-angle camera, and the electronic device uses the main camera and the wide-angle camera to image The video captured by the main camera can be simultaneously collected on the screen of the electronic device. image If you see this, your electronic device has a main camera. imageIf the camera shake becomes severe when the image is collected by the main camera, the electronic device can determine that the rotation angle of the electronic device is 40 degrees, and determine the second cropping percentage as 45% based on the rotation angle. In this case, the determined second cropping percentage of 45% is greater than the second preset cropping parameter of 40%, so that the image collected by the main camera can be cropped. image is over-trimmed image Since the visibility of the wide-angle camera is affected, the electronics may determine a first cropping parameter corresponding to the wide-angle camera as 50% based on the determined second cropping percentage of 45% corresponding to the main camera. Then, the electronics may calculate the first cropping parameter corresponding to the wide-angle camera based on the first cropping parameter of 50%. image Finally, the electronic device can crop the first image captured by the cropped wide-angle camera. image can be displayed.

[0065] What needs to be explained is that the wide-angle camera is better than the main camera. image If you use the same crop percentage, and therefore a crop percentage that is larger than the crop percentage corresponding to the main camera, because there is more content, the amount of video that can be retained is image The content is more. Therefore, the electronic device has a larger crop percentage and the images captured by the wide-angle camera are image Cropped and collected by the main camera image of image Close to the content image can be obtained, thereby achieving the effect of smooth replacement; and image This ensures a high visibility range and further improves the effectiveness of preventing camera shake.

[0066] It should be noted that the second preset trimming parameter and the first preset trimming parameter may be the same parameter or different parameters, and the embodiment of the present application is not limited thereto.

[0067] The image stabilization method provided in the present application can be applied to scenes where multiple cameras are used to improve the effect of image stabilization, and the electronic device is image The camera with the most content was used to take the picture. image Trim and shoot image The camera with the least amount of content was used to take the picture. image can be replaced with image This can ensure a visible range and further improve the effect of preventing camera shake.

[0068] Optionally, in an embodiment of the present application, the cropping parameters may be pre-set by a user.

[0069] Exemplarily, before the above step 201, the method may further include the following steps A1 and A2.

[0070] In step A1, the electronic device receives a first input from a user.

[0071] For example, the first input may include a tap input by a user on a screen, or a voice command input by a user, or a specific gesture input by a user, and the specific input may be determined according to practical requirements, and the embodiments of the present application are not limited thereto.

[0072] The specific gesture in the embodiment of the present application may be any one of a single tap gesture, a slide gesture, a drag gesture, a pressure recognition gesture, a long press gesture, an area change gesture, a double press gesture, and a double tap gesture. The tap input in the embodiment of the present application may be a single tap input, a double tap input, or an arbitrary number of tap inputs, and may be a long press input or a short press input.

[0073] In step A2, in response to the first input, the electronic device displays a trimming parameter setting interface.

[0074] The cropping parameter setting interface includes at least one parameter setting box, and each parameter setting box is for setting one cropping parameter.

[0075] For example, as shown in (a) of FIG. 4, when the electronic device displays the preview interface 33 of the main camera, if the user wants to set the default cropping parameters and maximum cropping parameters of the main camera, the user may long press the "Set" button 34. At this time, as shown in (b) of FIG. 4, the electronic device displays a cropping parameter setting interface 35, in which two parameter setting boxes are displayed, which are the default cropping parameters and the maximum cropping parameters, respectively. The cropping parameter setting box 35 also displays the original drawing surrounded by a black frame, which indicates the initial display content of the original drawing. If the user inputs 20% in the default cropping parameter setting box, the electronic device will prompt the user to enter the 20% cropping parameter. image View estimates after trimming image A dotted frame 36a is displayed to indicate the content. If the user enters 35% in the maximum cropping parameter setting box, the electronic device will display a 35% cropping value to the user. image View estimates after trimming image One dotted frame 36b is displayed to indicate the contents, so that the user can set the cropping parameters as required.

[0076] Exemplarily, when the electronic device has at least two cameras, the cropping parameter setting interface may include at least two areas, and different areas are for setting cropping parameters of different cameras.
