Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.

The terms "first," "second," and the like in the description of the present application, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the objects identified by "first," "second," etc. are generally of a type not limited to the number of objects, for example, the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The terms "at least one", and the like in the description of the present application mean that they encompass any one, any two, or a combination of two or more of the objects. For example, at least one of a, b, c (item) may represent: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", wherein a, b, c may be single or plural. Similarly, the term "at least two" means two or more, and the meaning of the expression is similar to the term "at least one".

The shooting method, the terminal, the electronic device and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

The shooting method, the terminal, the electronic device and the readable storage medium provided by the embodiment of the application can be applied to a scene shot by the electronic device, especially a scene shot under the condition that the electronic device is fixed at a certain position.

Along with the development of shooting technology, the long-focus lens can clearly shoot objects at longer distances, so that the long-focus lens is widely applied to various scenes and is accepted by common users and professional photographers.

In order to obtain a better anti-shake experience under high power zoom, users typically fix an electronic device in a certain position for shooting. For example, a user may take a photograph by placing the electronic device on a tripod. In general, in order to maintain the stability of a photographed image on a tripod, OIS will stop anti-shake after controlling the lens of a camera at the center position of the photographed image. After the OIS stops anti-shake, if the user needs to change the shooting object, the mobile electronic device is required to shoot and obtain a corresponding image or video.

However, under high-power zooming, any fine shake of the electronic device is amplified, which results in high difficulty in controlling the focusing of the tele camera of the electronic device during shooting by a user, and easily causes the preview screen under high power to deviate from the object. As such, the difficulty of focusing by a user during the process of moving the electronic device or foot rest is high.

In the shooting method, the terminal, the electronic device and the readable storage medium provided by the embodiment of the application, the image displayed by the main preview window can be determined by shooting the picture range indicated by the first mark of the auxiliary preview window in the preview interface, so that the required image or video can be shot. Therefore, under the foot rest mode, the electronic equipment can change the image displayed by the main preview window by changing the picture range indicated by the first mark in the auxiliary preview window, and the user does not need to manually move the electronic equipment to aim at a shooting object to be shot, so that quick focusing can be realized, the operation is simple, and the efficiency of shooting images or videos is improved.

The execution subject of the shooting method provided by the embodiment of the application can be a terminal. The terminal may be an electronic device or a component in the electronic device, such as an integrated circuit or chip, for example. The photographing method provided by the embodiment of the application will be exemplarily described below by taking an electronic device as an example.

An embodiment of the present application provides a photographing method, and fig. 1 shows a flowchart of the photographing method provided by the embodiment of the present application, where the method may be executed by an electronic device. As shown in fig. 1, the photographing method provided by the embodiment of the present application may include the following steps 101 and 102.

And step 101, displaying a shooting preview interface of the electronic equipment in a foot rest mode.

The shooting preview interface comprises a main preview window and an auxiliary preview window, wherein the auxiliary preview window is used for displaying preview images acquired by a camera of the electronic equipment, the auxiliary preview window comprises a first mark, the first mark indicates a first picture range, and the main preview window is used for displaying images corresponding to the first picture range.

In some embodiments of the present application, the stand mode may be a mode in which a user places the electronic device on a stand to stabilize the electronic device and improve the photographing quality when the electronic device photographs an image or video. That is, stable images or videos can be better shot in the foot rest mode, and shaking or shaking of the handheld electronic device during shooting is avoided.

In some embodiments of the present application, the preview image collected by the camera of the electronic device displayed in the auxiliary preview window may be an image collected by the camera of the electronic device in real time, or may be a buffered frame stored according to the electronic device during previewing. It may be appreciated that, in the case where the auxiliary preview window displays a buffered frame acquired by a camera of the electronic device, the frame range corresponding to the preview image may be a frame range corresponding to a camera with a maximum field of view, for example, the buffered frame may be an image acquired by a wide-angle camera.

In some embodiments of the present application, the image corresponding to the first frame range may be at least part of the preview images displayed in the auxiliary preview window.

Illustratively, the first identifier may be a region of interest box (region of interest, ROI) in the auxiliary preview window, and the image corresponding to the first screen range may be a framed image in the ROI box.

For example, the first identifier may be a mark displayed in the auxiliary preview window, such as an arrow, to indicate a relative position of the image corresponding to the first screen range in the preview image displayed in the auxiliary preview window.

In some embodiments of the present application, the image corresponding to the first frame range displayed in the main preview window is an image required by a user.

It should be noted that, the camera related to the embodiment of the present application may be a camera of the electronic device, or may be a movable camera externally connected to the electronic device. It can be understood that the camera related to the embodiment of the application can be a common camera, a wide-angle camera, a long-focus camera and an anti-shake camera with OIS function. The application is not limited in this regard.

In some embodiments of the present application, in the case where the camera is an anti-shake camera without OIS function, the preview image displayed in the auxiliary preview window in the preview interface may be obtained by digitally zooming an image acquired by the camera with an electronic device, where the camera is a wide-angle camera. In the case that the camera is an anti-shake camera with OIS function, the preview image displayed by the auxiliary preview window in the shooting preview interface may be acquired by the camera under the full view angle. It can be understood that the image acquired by the camera under the full view angle can be the image of the maximum range acquired by the camera in the rotation process.

For example, the preview image may be an image obtained by stitching the collected images during the rotation of the camera according to the rotation sequence of leftmost, uppermost, rightmost and bottommost.

In some embodiments of the present application, the camera of the electronic device may be any camera on the electronic device.

Further, if the electronic device has a plurality of cameras, the camera of the electronic device may be a camera with the largest field of view among the plurality of cameras of the electronic device. In this way, the shot region corresponding to the preview image displayed in the auxiliary preview window can be maximized, so that the first screen range selectable by the user is widest.

For example, assuming the electronic device has a periscope camera, the electronic device may display an image acquired by the periscope camera at a full view angle in an auxiliary preview window.

In some embodiments of the present application, the electronic device may display the shooting preview interface after entering the shooting mode.

In some embodiments of the present application, the display area of the auxiliary preview window may be any display area of the shooting preview interface. It will be appreciated that the shape and size of the display area may be user-set or may be default to the electronic device. The embodiment of the present application is not particularly limited.

For example, the display area of the auxiliary preview window may be a square display area in the upper right corner of the photographing preview interface; alternatively, the display area of the auxiliary preview window may be a circular display area in the lower left corner of the photographing preview interface.

For example, the display area of the auxiliary preview window may be one fourth of the display area of the photographing preview interface; alternatively, the display area of the auxiliary preview window may be one fifth of the display area of the shooting preview interface, which is not limited in the embodiment of the present application.

In some embodiments of the present application, the main preview window and the auxiliary preview window may be displayed on the shooting preview interface independently, or may be displayed on the shooting preview interface in a superimposed manner with different display sizes.

For example, the main preview window and the auxiliary preview window may be displayed in a left-right adjacent form in the photographing preview interface.

For example, the auxiliary preview window may be displayed in the form of a small window at the upper right corner of the main preview window.

For example, the main preview window and the auxiliary preview window may be displayed in the photographing preview interface in a superimposed manner with a preset transparency.

For example, the main preview window and the auxiliary preview window described above may be displayed in the photographing preview interface in a superimposed manner with a transparency of 30%.

For example, the auxiliary preview window described above may be displayed in a completely opaque form in the photographing preview interface.

The auxiliary preview window may also be displayed in a floating manner in the photographing preview interface, and may be moved in the photographing preview interface as the user drags the auxiliary preview window.

In some embodiments of the present application, the display position of the auxiliary preview window in the shooting preview interface may be fixed or non-fixed.

For example, the display position of the auxiliary preview window may be fixed at the upper right corner of the photographing preview interface.

If the electronic device is a folding screen, the auxiliary preview window may be displayed on one of the display screens and the main preview window on the other display screen.

Step 102, generating an image or video based on the image corresponding to the first picture range.

In some embodiments of the present application, the electronic device may generate an image or video required by the user using the image corresponding to the first screen range as the image to be photographed.

According to the shooting method provided by the embodiment of the application, the image displayed by the main preview window can be determined by shooting the picture range indicated by the first mark of the auxiliary preview window in the preview interface, so that the required image or video can be shot. Therefore, under the foot rest mode, the electronic equipment can change the image displayed by the main preview window by changing the picture range indicated by the first mark in the auxiliary preview window, and the user does not need to manually move the electronic equipment to aim at a shooting object to be shot, so that quick focusing can be realized, the operation is simple, and the efficiency of shooting images or videos is improved.

In some embodiments of the present application, as shown in fig. 2 in conjunction with fig. 1, after the step 101, the photographing method provided in the embodiment of the present application may further include the following steps 103 and 104.

Step 103, receiving a first input of a user.

Step 104, in response to the first input, updating the display position of the first mark in the auxiliary preview window and updating the image displayed by the main preview window.

The first input may be used to select an object corresponding to the first screen range from the preview images displayed in the auxiliary preview window. I.e. the first input may be a selection input of an object corresponding to the first screen range.

In some embodiments of the present application, the image corresponding to the first frame range may be an image corresponding to a frame range that the user wants to capture, or an image corresponding to a frame range that the user is interested in.

Illustratively, the first input includes, but is not limited to: the user inputs the first identifier through a touch device such as a finger or a stylus, or inputs a voice command input by the user, or inputs a specific gesture input by the user, or inputs other feasibility, and the embodiment of the application is not limited. The specific gesture in the embodiment of the application can be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture and a double-click gesture; the click input in the embodiment of the application can be single click input, double click input or any time click input, and the like, and can also be long-press input or short-press input. In practical implementation, the method can be determined according to practical use requirements, and the embodiment of the application is not limited.

In some embodiments of the present application, the first input may include a drag input to the first logo, or the first input may include a click input to the auxiliary preview window.

In some embodiments of the application, the electronic device may display an ROI frame in the auxiliary preview window through which the first frame range may be framed in the preview image displayed in the auxiliary preview window.

For example, the first input may be a drag input of the ROI box in the auxiliary preview window by the user, so as to trigger the electronic device to determine an image corresponding to the first screen range selected by the user from the preview image.

In some embodiments of the present application, the electronic device may receive a click input from a user on a different location in the auxiliary preview window, and directly display the first identifier at the input location of the click input, thereby changing a first frame range of the first identifier that is framed in the preview image displayed in the auxiliary preview window.

For example, the first input may be a click input of the auxiliary preview window by the user, so that the first identifier is directly displayed at an input position of the click input, thereby triggering the electronic device to determine an image corresponding to the first screen range selected by the user from the preview image.

In this way, the electronic device can change the display position of the first identifier in the auxiliary preview window through the dragging input of the first identifier by the user or the clicking input of the auxiliary preview window, so that the image displayed by the main preview window is changed without changing the image displayed by the main preview window by the mobile electronic device. Therefore, the user can conveniently and quickly determine the object to be shot, and the flexibility and accuracy of selecting the shot object are improved.

In some embodiments of the present application, after receiving the first input of the user, the electronic device may update, according to the image corresponding to the first screen range selected by the user, the display position of the first identifier in the auxiliary preview window, so as to update the image corresponding to the first screen range indicated by the first identifier displayed in the main preview window.

For example, as shown in fig. 3A, the electronic device may display a "puppy", "football", and an ROI frame 32 in the auxiliary preview window 31, where the "puppy" is included in the ROI frame 32, that is, the image corresponding to the above-described first screen range is a puppy image. At this time, the "puppy" is displayed in the main preview window 33.

The electronic device may then receive a user drag input of the ROI frame 32, dragging the ROI frame 32 onto "football", so that the electronic device may display "puppy", "football" and ROI frame 32 in the auxiliary preview window 31, including "football" in the ROI frame 32, as shown in fig. 3B. And, the electronic device may display "football" in the main preview window.

Alternatively, the electronic device may receive a user's click input of "football" in the auxiliary preview window 31, and the electronic device may directly display the ROI box 32 on "football", so that the electronic device may display "puppy", "football" and ROI box 32 in the auxiliary preview window 31, including "football" in the ROI box 32, as shown in fig. 3B. And, the electronic device may display "football" in the main preview window.

It should be noted that, the steps 103 and 104 may be performed before the step 102, or may be performed after the step 102. The above embodiment is described as an example in which step 103 and step 104 may be performed before step 102. It will be appreciated that if steps 103 and 104 are performed after step 102, the electronic device may perform step 102 once again after performing step 104 to obtain a different image or video.

In this manner, since the electronic device can receive the first input from the user, the display position of the first identifier in the auxiliary preview window is changed, thereby changing the image displayed by the main preview window without the mobile electronic device changing the image displayed by the main preview window. Therefore, a user can conveniently and quickly select an object to be shot in the preview image, the accuracy of selecting the shot object is improved, and the flexibility of shooting images or videos is improved.

In some embodiments of the present application, the auxiliary preview window may include a second identifier, and the first input includes a click input or a slide input of the second identifier.

In some embodiments of the present application, the second identifier may be an identifier indicating that the user moves the first identifier.

For example, the second identifier may be a plurality of arrows in different directions, so as to indicate that the user may move the first identifier in different directions, so as to change the display position of the first identifier in the auxiliary preview window, thereby changing the first screen range, and further changing the image corresponding to the first screen range displayed in the main preview window.

In some embodiments of the present application, in the case where the second identifier may be included in the auxiliary preview window, the first input may be a click input or a slide input of the second identifier by the user, so that the electronic device may move the first identifier to flexibly select an image corresponding to the first screen range from the preview images.

For example, in connection with fig. 3A, as shown in fig. 4A, the electronic device may display an arrow around the ROI frame 32 to prompt the user that the ROI frame 32 may be moved in the direction indicated by the arrow.

Illustratively, as shown in FIG. 4A, the user may click on the right arrow, triggering the electronic device to control movement of the ROI box 32 to the right. Thus, as shown in FIG. 4B, the electronic device can change the display position of the ROI box 32 and update the "puppy" in the main preview window 40 to "football".

In some embodiments of the application, the user may trigger the electronic device to control the movement of the first identifier in either direction in the preview image by a click input or a slide input of the second identifier. It is understood that any direction may include any possible direction, up, down, left, right, up-left, up-right, down-left, down-right, etc.

Illustratively, the first identification is an ROI box. If the image corresponding to the picture range which the user wants to select is located at the right lower part of the image corresponding to the picture range which is framed by the ROI frame, the user can drag an arrow indicating the right lower direction, namely the second mark, so that the electronic equipment can be triggered to control the ROI frame to move right lower so as to select the image corresponding to the required picture range.

Illustratively, the first identification is an ROI box. If the image corresponding to the picture range to be selected by the user is located at the upper left of the image corresponding to the picture range selected by the ROI frame, the user may directly click an arrow indicating the upper left direction, that is, the second identifier, so that the electronic device may be triggered to control the ROI frame to move to the upper left so as to select the image corresponding to the required picture range.

In this way, since the display position of the first logo in the auxiliary preview window and the image displayed in the main preview window can be updated by the click input or the slide input of the second logo. Thus, flexibility and accuracy in selecting a photographed object can be improved.

In some embodiments of the present application, as shown in fig. 5 in conjunction with fig. 1, after the step 101, the photographing method provided in the embodiment of the present application may further include the following steps 105 and 106.

Step 105, the electronic device receives a second input of the user in case the auxiliary preview window and the main preview window display images acquired by the first camera.

In some embodiments of the present application, the first camera may be any camera with an anti-shake function of the electronic device. Namely, the first camera is a camera with a rotatable lens.

In some embodiments of the present application, the above-mentioned "the auxiliary preview window and the main preview window display the image acquired by the first camera" may represent: the preview image displayed by the auxiliary preview window and the image displayed by the main preview window are images acquired by the same camera. It can be understood that the preview image displayed by the auxiliary preview window may be an image acquired by the first camera in real time, or may be a buffered frame image acquired according to the first camera.

In some embodiments of the present application, the second input may be an input that changes a first screen range indicated by the first identifier.

The second input may be, for example, a user sliding input of the first identifier to trigger the electronic device to change the first screen range indicated by the first identifier.

The second input may be, for example, a user sliding input of the auxiliary preview window to trigger the electronic device to change the first screen range indicated by the first identification.

And step 106, in response to the second input, updating the first identifier and the display parameters of the first picture range indicated by the first identifier.

The first identifier and the display parameter of the first picture range have an association relationship with the input parameter of the second input and the maximum anti-shake range of the first camera.

In some embodiments of the present application, the display parameters of the first frame range may include a display size and image content of an image corresponding to the first frame range.

In some embodiments of the present application, the input parameters of the second input may include an input position, an input direction, and a trajectory of the input.

In some embodiments of the present application, the maximum anti-shake range of the first camera may refer to a maximum anti-shake angle of the first camera. It can be understood that the larger the anti-shake range of the first camera, the larger the anti-shake angle of the first camera, and the larger the corresponding field of view range.

In some embodiments of the present application, if the field of view of the first camera is larger, the adjustable space of the display parameters of the first identifier and the first frame range is larger.

In some embodiments of the present application, the "the first identifier, the display parameter of the first frame range and the input parameter of the second input, and the maximum anti-shake range of the first camera have an association relationship" may indicate: after the electronic device receives the second input of the user, it can determine how to update the first identifier and the display parameters of the first frame range according to the input parameters of the second input and the maximum anti-shake range of the first camera.

Illustratively, the second input is exemplified as the user sliding the first identification to the right. The electronic device may control the first identifier to move from an input start position of the second input along the input direction and the input track according to the input parameter of the second input, and move the first identifier to an input end position of the second input under the condition that the maximum anti-shake range of the first camera is not exceeded. It will be appreciated that the display position of the first logo and the first screen range indicated by the first logo also change, i.e. the display position of the first logo and the display parameters of the first screen range also change.

In some embodiments of the application, the electronic device may receive user input to the auxiliary preview window, change the preview image displayed by the auxiliary preview window, or change the magnification of the preview image.

For example, the electronic device may receive user input of a double-finger pinch of the auxiliary preview window, reducing magnification of the preview image displayed by the auxiliary preview window.

For example, the electronic device may receive a user sliding input to the left of the auxiliary preview window in which an image to the left of the preview image is displayed.

In some embodiments of the present application, the electronic device may reduce the preview image displayed in the auxiliary preview window to an image corresponding to the maximum field of view of the first camera in the process of inputting the second input by the user; after the user finishes inputting the second input, amplifying the preview image displayed by the auxiliary preview window to an image corresponding to the field of view range corresponding to the zoom magnification currently selected by the first camera, so that the user can more flexibly and accurately select the object to be shot in the auxiliary preview window.

In some embodiments of the present application, the electronic device may control the rotation of the first camera according to the position information of the image corresponding to the first frame range indicated by the first identifier in the preview image, so that the image shot by the first camera under the currently used zoom magnification is the image corresponding to the first frame range selected by the user from the preview image.

Illustratively, as shown in fig. 4A, in conjunction with the main preview window 40 shown in fig. 4A, when the user wants to shoot "football" on the right side of "puppy", the ROI frame 32 may be dragged rightward in the auxiliary preview window 41, dragging the ROI frame 32 onto "football", i.e., the second input described above. Thus, as shown in fig. 4B, according to the position information of the "football" in the preview image displayed in the auxiliary preview window 41, the electronic device may be triggered to rotate the first camera, so that the first camera rotates to an angle capable of shooting the "football", and the rotated first camera is collected in the main preview window 40 containing the "football" picture display.

It should be noted that, the steps 105 and 106 may be performed before the step 102, or may be performed after the step 102. The above embodiment is described as an example in which step 105 and step 106 may be performed before step 102. It will be appreciated that if steps 105 and 106 are performed after step 102, the electronic device may perform step 102 once again after performing step 106 to obtain a different image or video.

Therefore, the electronic equipment can update the first mark and the display parameter of the first picture range indicated by the first mark according to the input parameter input by the user and the maximum anti-shake range of the camera, so that the electronic equipment can shoot and obtain a required image or video based on the updated display parameter of the first picture range, and the efficiency of shooting the image or video is improved.

In some embodiments of the present application, the photographing method provided in the embodiment of the present application may further include the following steps a and b.

And a, calculating a rotation parameter of the first camera based on the position information of the image corresponding to the first picture range indicated by the first identifier in the preview image.

And b, controlling the first camera to rotate based on the rotation parameters.

In some embodiments of the present application, the rotation parameters may include: rotation angle and motor travel.

In some embodiments of the present application, the position information of the image corresponding to the first frame range indicated by the first identifier in the preview image may be represented by coordinates of pixels of the image corresponding to the first frame range indicated by the first identifier in the preview image. That is, the position information of the image corresponding to the first screen range indicated by the first identifier in the preview image includes: coordinate information of an image corresponding to the first picture range indicated by the first identifier in the preview image.

In some embodiments of the present application, after calculating the rotation parameter of the first camera, the electronic device needs to convert the rotation parameter of the first camera into a hall value, so that the electronic device can control the rotation of the first camera based on the hall value. That is, the electronic device may convert the coordinate information of the image corresponding to the first screen range indicated by the first identifier in the preview image into a hall value, so that the electronic device controls the first camera to rotate based on the hall value.

It should be noted that the rotation operation of the first camera is generally implemented by a hall sensor. The electronic equipment can sense the magnetic field of the magnet on the first camera through the Hall sensor, and in the rotating process of the first camera, the distance between the magnet and the Hall sensor is different, so that sampling values obtained by the Hall sensor are different, namely, the Hall values are different. Therefore, the current angle of the first camera can be determined through the Hall value.

In some embodiments of the present application, in a process of converting coordinate information of an image corresponding to a first frame range indicated by the first identifier in a preview image into a hall value, the electronic device calculates a target rotation parameter, where the target rotation parameter includes: the rotation angle and the motor travel of the first camera are converted into Hall values.

It should be noted that, the above-mentioned motor travel may refer to an effective travel of the motor, that is, a range of shooting angles adjusted by the first camera when the motor drives the rotatable camera to rotate. That is, the above-described motor stroke may indicate the adjustment range of the photographing angle of the first camera. It will be appreciated that a change in the angle of capture of the first camera may result in a consequent change in the range of images captured by the first camera.

In some embodiments of the present application, the electronic device may convert the effective motor stroke corresponding to the first camera into the selectable pixel movement range in the preview image through the following formula (1) and formula (2).

Wherein θ _x X is the maximum rotatable angle on the X axis of the first camera _x For theta _x The corresponding maximum stroke of the motor is expressed in mu m; θ _y X is the maximum rotatable angle on the y axis of the first camera _y For theta _y Corresponding maximum motor rowThe unit is μm; EFL is the effective focal length of the first camera.

Wherein M is _xpixel A single-side maximum pixel range selectable on the x-axis in the preview image; w (W) _x A unit pixel size on the x-axis for the preview image; m is M _ypixel A single-sided maximum pixel range selectable on the y-axis for the preview image; w (W) _y The unit pixel size on the y-axis for the preview image.

It can be understood that, as can be seen from the above formula (1) and formula (2), on the one hand, the larger the rotatable angle of the first camera, the larger the moving stroke of the motor, and the larger the range of the image corresponding to the first frame range indicated by the selectable first identifier in the preview image. On the other hand, the larger the zoom magnification of the first camera, the larger the change in image content due to the movement of the motor. Therefore, the larger the rotatable angle and zoom magnification of the first camera, the larger the field of view variation benefit caused by the movement of the motor. In other words, the first camera is rotated by a small angle, and the image displayed by the main preview window can be changed greatly. In this way, the selectable pixel range can be further enlarged, so that the image corresponding to the first screen range indicated by the first identifier can be more accurately determined from the preview image.

In some embodiments of the present application, the electronic device may use the following formula (3) to display the pixel coordinate O (u _x ，u _y ) Conversion to Hall value indicated position O' (v _x ,v _y )。

Wherein h is _xcenter The first camera is a Hall center on an x-axis; h is a _ycenter The first camera is a Hall center on a y axis; u (u) _x0 A pixel coordinate value center of the preview image on the x-axis; u (u) _y0 A pixel coordinate value center of the preview image on the y axis; gyrogain _x A gyroscope gain value of the first camera on the x axis; gyrogain _y Is the gyroscope gain value of the first camera on the y-axis.

It should be noted that, the hall center of the first camera may indicate a position when the camera lens is located at the center. The electronic device can correspond the pixel coordinate value center of the preview image to the Hall center of the first camera, so that the electronic device can control the first camera to rotate to a position where the image corresponding to the first picture range indicated by the first identifier can be shot according to the position information of the image corresponding to the first picture range indicated by the first identifier in the preview image, and the target image can be shot.

Therefore, the electronic equipment can convert the position information of the image corresponding to the first picture range indicated by the first identifier into a Hall value in the preview image, and according to the Hall value, the motor of the camera is used for controlling the lens of the camera to rotate to a position where the image corresponding to the first picture range indicated by the first identifier can be shot. Therefore, the camera can quickly focus the object to be shot, and the efficiency of shooting images or videos is improved.

In some embodiments of the present application, after the electronic device controls the rotation of the first camera, the photographing method provided in the embodiment of the present application may further include the following step c.

And c, displaying the image which is acquired by the rotated first camera and corresponds to the first picture range on the main preview window.

In some embodiments of the present application, the electronic device may cause the first camera to focus on the object to be photographed after controlling the first camera to rotate. And displaying the image acquired by the rotated first camera in real time in the main preview window.

In some embodiments of the present application, in a process that a user selects an image corresponding to a first frame range indicated by a first identifier from preview images displayed in an auxiliary preview window, when the electronic device receives a second input of the user, the electronic device may enlarge and display the preview images and the first identifier displayed in the auxiliary preview window, so that the user may more accurately determine the image corresponding to the first frame range.

Illustratively, as shown in FIG. 6A, the electronic device displays a preview image 60 in the auxiliary preview window. When the electronic device receives an input that the user slides the ROI frame 61, the electronic device may enlarge and display the preview image 60 and the ROI frame 61. As shown in fig. 6B, the electronic device may enlarge and display the preview image 60 and the ROI frame 61 so that the user may more precisely determine the object corresponding to the first screen range.

It will be appreciated that, since the range of movement of the motor of the first camera is limited, the range of fields of view corresponding to the preview image actually displayed by the electronic device is limited. In this way, under the condition that the image shot by the first camera can cover the image corresponding to the first picture range selected by the user through the first identifier, the electronic device can enlarge and display the image corresponding to the selected first picture range in the auxiliary preview window; under the condition that the image shot by the first camera cannot cover the image corresponding to the first picture range selected by the user through the first identifier, the electronic equipment can receive the input of the user, change the magnification of the image corresponding to the first picture range displayed by the auxiliary preview window, and reselect the object to be shot, so that the image or the video is shot again.

Therefore, the electronic device can display the image collected by the rotated camera in real time in the main preview window, so that a user can judge whether the image collected by the camera is a required image or not through the image displayed in real time in the main preview window, and the efficiency of shooting images or videos can be improved.

In some embodiments of the application, the electronic device may include a second camera and a third camera.

The auxiliary preview window is used for displaying a first image, the first image is obtained by cutting an image collected by the second camera, the main preview window is used for displaying a second image, the second image is obtained based on the image collected by the third camera, and the field of view range corresponding to the first image is the same as the maximum field of view range of the third camera.

In some embodiments of the present application, the second camera and the third camera may be any two different cameras in the electronic device. It can be understood that the second camera and the first camera may be the same or different; the third camera may be the same as or different from the first camera.

In some embodiments of the present application, the "the field of view range of the second camera is greater than or equal to the field of view range of the third camera" may indicate that: the first image acquired by the second camera may be an image with a picture range greater than a picture range corresponding to the second image acquired by the third camera, so that a user may determine an object to be photographed through the first identifier from the first image displayed in the auxiliary preview window.

In some embodiments of the present application, the electronic device may directly display the image acquired by the third camera as the second image in the main preview window; or, the electronic device may further display the image acquired by the third camera as the second image in the main preview window after clipping the image.

In some embodiments of the present application, the "the field of view range corresponding to the first image is the same as the maximum field of view range of the third camera" may indicate that: when the electronic equipment shoots and previews through the second camera and the third camera, the second camera and the third camera can be aligned in the field of view range, so that the electronic equipment can determine an object to be shot from the image acquired by the third camera according to the selection of a user in the image acquired by the second camera.

Therefore, the electronic device can take the images acquired by the cameras with larger overview field range as the first images in the auxiliary preview window, and the images acquired by the cameras with smaller overview field range as the second images in the main preview window, so that the electronic device can take the images of the shooting objects through different cameras according to the user demands, and the flexibility of shooting the images or videos is improved.

In some embodiments of the present application, the shooting preview interface may further include a panoramic preview window, where the panoramic preview window is used to display an image obtained by stitching at least two frames of images displayed in the main preview window.

In some embodiments of the present application, the panoramic preview window may be displayed in the shooting preview interface independently, or may be displayed in a superimposed manner on the shooting preview interface with a preset transparency.

In some embodiments of the present application, after the step 101, the photographing method provided in the embodiment of the present application may further include the following steps 107 to 110.

Step 107, receiving a third input from the user.

Step 108, in response to the third input, displaying a third image in the panoramic preview window.

In some embodiments of the present application, the third input may be used to select the object to be photographed from the preview image displayed in the auxiliary preview window, i.e., the third input may be a selection input of the object to be photographed.

For example, the third input may be a sliding input initiated by the user from any position in the preview image, so as to trigger the electronic device to collect an image on a sliding track of the sliding input.

For example, the third input may be a drag input of the user on the first identifier in the preview image, so as to trigger the electronic device to collect an image including the shooting object determined by the first identifier.

In some embodiments of the present application, the third image may be an image obtained by stitching at least two frames of images obtained by the electronic device according to the third input. It is understood that the at least two frames of images may be images with consecutive picture contents.

Illustratively, the third input is exemplified as a right swipe. As shown in fig. 7, the electronic device may display an image containing "puppy" and "football" on the auxiliary preview window 71 of the photographing preview interface 70. The electronic device may then receive a user's sliding input to the right of the "puppy" displayed on the auxiliary preview window 71, and may trigger the electronic device to control the camera to take an image of the "puppy" and its right side, resulting in an image containing the "puppy" and an image containing the "football". The electronic device may then stitch the image containing the "puppy" and the image containing the "football" to obtain a third image.

Illustratively, the third input is exemplified as a slide down. As shown in fig. 8, the electronic device may display an image containing a "puppy" on the auxiliary preview window 81 of the photographing preview interface 80. The electronic device may then receive a user's downward sliding input of the "puppy" displayed on the auxiliary preview window 81, and may trigger the electronic device to control the camera to capture an image of the "puppy" and objects in front of it, capturing an image containing the "puppy" and objects in front of the "puppy". The electronic device may then stitch the image containing the "puppy" and the image of the object in front of the "puppy" to obtain a third image.

In some embodiments of the present application, for the detailed description of controlling the camera to perform shooting according to the position information of the shooting object in the preview image selected by the electronic device according to the third input, reference may be made to the related description in the above steps a to c, which is not repeated herein.

In some embodiments of the present application, the electronic device may stitch at least two frames of images obtained by photographing to obtain a panoramic image including all the picture contents in the at least two frames of images, and display the panoramic image in a panoramic preview window.

In some embodiments of the present application, the electronic device may display the preview image in the auxiliary preview window during the input of the third input; displaying an image corresponding to the first picture range in the main preview window; the spliced image can be displayed in real time in a panoramic preview window in the shooting preview interface.

It may be understood that the electronic device displaying the stitched image in the panoramic preview window in real time may refer to: in the process of collecting at least two frames of images, the camera of the electronic equipment can splice and display the at least two frames of images collected by the camera in real time.

In some embodiments of the present application, the display area of the panoramic preview window may be an area other than the display area of the main preview window and the display area of the auxiliary preview window in the photographing preview interface. The panoramic preview window may be displayed superimposed on the display area of the main preview window. The embodiment of the present application is not particularly limited.

Illustratively, as shown in fig. 9, the electronic device may display a main preview window 90 and an auxiliary preview window 91 on the photographing preview interface, and the electronic device may further superimpose and display a panoramic preview window 92 on the main preview window 90 to display the stitched image in real time.

In some embodiments of the present application, the electronic device may display a control in a panorama stitching mode on the shooting preview interface, so that the electronic device may receive an input from a user to the control, and control the shooting preview interface to enter the panorama stitching mode.

In some embodiments of the present application, after the electronic device displays the auxiliary preview window on the photographing preview interface, a prompt message "slide the first mark for panoramic stitching" may be displayed to prompt the user that the panoramic image may be photographed by sliding the first mark.

In this way, the electronic device can control the camera to shoot at least two frames of images through the input of the preview images displayed in the auxiliary preview window by the user, and the user does not need to manually rotate the electronic device to shoot. Therefore, the required image can be accurately shot, the problems of image fracture and deformation caused by shooting the panoramic image by a user in a handheld mode are avoided, and the speed and the efficiency of shooting the panoramic image can be improved.

Step 109, receiving a fourth input from the user.

And 110, responding to the fourth input, updating the image corresponding to the first picture range, and displaying the fourth image in the panoramic preview window.

The image content of the fourth image includes the image content of the third image, and the image range corresponding to the fourth image is larger than the image range corresponding to the third image.

In some embodiments of the present application, the fourth input and the third input may be two inputs having opposite input directions, and the object selected by the fourth input is different from the object selected by the third input.

In some embodiments of the present application, the fourth input may be used to select an unselected subject to be photographed from the preview image displayed in the auxiliary preview window, that is, the fourth input may be a selection input of the unselected subject to be photographed.

For example, the fourth input may be a sliding input from any position in the preview image by the user, so as to trigger the electronic device to collect an image of the shooting object determined by the sliding track containing the sliding input.

For example, the fourth input may be a drag input of the user to the first identifier in the preview image, so as to trigger the electronic device to acquire an image of the shooting object determined by the ROI frame.

It is understood that the at least one frame of image acquired by the third image and the electronic device according to the fourth input may be images with continuous picture content, and the third image is different from the at least one frame of image acquired according to the fourth input.

In some embodiments of the present application, if the electronic device receives the third input and the fourth input in the case where the starting positions of the third input and the fourth input are the same, the electronic device may directly stitch at least one frame of image captured in response to the third input and then use the stitched at least one frame of image captured in response to the fourth input as a third image, stitch the third image and the fifth image and then use the stitched at least one frame of image captured in response to the fourth input as a fifth image, and obtain a fourth image.

For example, the electronic device may control the shooting preview interface to enter the panorama stitching mode in the foot stand mode. As shown in fig. 10A, the electronic device may display an identification 101 of the foot stand mode on the shooting preview interface 100, indicating that the panorama stitching mode has been entered. In this mode, the electronic device may receive a sliding input from the center position to the right on the auxiliary preview window 102, i.e., a third input, and control the camera to take a photograph, as shown in fig. 10B, of an image 1 containing "puppy" and an image 2 containing "football". The electronic device may then display the stitched image of image 1 and image 2 in the panoramic preview window 103 of the capture preview interface 100.

Then, as shown in fig. 10B, the electronic device may receive a sliding input of the user from the center position to the left, that is, a fourth input, and control the camera to perform shooting, as shown in fig. 10C, to obtain an image 3 including "person", and splice the image 3 with an image obtained by splicing the image 1 and the image 2, and then display the spliced image in the panoramic preview window 103 of the shooting preview interface 100.

In some embodiments of the present application, if the electronic device receives the third input and the fourth input when the starting positions of the third input and the fourth input are different, the electronic device may stitch at least one frame of image captured in response to the third input and then use the stitched at least one frame of image captured in response to the fourth input as a third image, stitch at least one frame of image different from the third image and then use the stitched at least one frame of image captured in response to the fourth input and then use the stitched at least one frame of image as a fifth image, and stitch the third image and the fifth image to obtain a fourth image.

Then, the electronic device may receive a sliding input to the left, i.e., a fourth input, from the end position of the sliding input to the right, and control the camera to take a photograph, which results in an image 1 containing "puppy", an image 2 containing "football", and an image 3 containing "person". As shown in fig. 10C, the electronic device may display an image obtained by stitching an image 3 including "person" with an image 1 including "puppy" and an image 2 including "football" obtained by sliding input to the right in the panoramic preview window 103 of the photographing preview interface 100.

Therefore, the electronic equipment can sequentially acquire different images through two inputs to splice, so that the finally obtained spliced image contains a larger view field, and panoramic shooting can be realized in a foot rest mode.

In some embodiments of the present application, before the step 101, the photographing method provided in the embodiment of the present application may further include the following steps 111 and 112. The step 101 may include a step 101a described below.

And 111, displaying an initial preview interface, wherein the zooming magnification corresponding to the image displayed in the initial preview interface is smaller than a first threshold value.

In some embodiments of the present application, the initial preview interface may be a preview interface that does not include an auxiliary preview window.

For example, the initial preview interface may contain only images captured in real time by the camera of the electronic device.

In some embodiments of the present application, the zoom magnification corresponding to the image displayed in the initial preview interface may indicate a degree to which the camera of the electronic device enlarges or reduces the image including the photographing object. It can be appreciated that the larger the zoom magnification of the camera of the electronic device, the smaller the field of view range corresponding to the image displayed in the initial preview interface.

Exemplarily, assuming that the zoom magnification of the camera of the electronic device is 2×, the corresponding focal length thereof is 3.6mm, and the field of view corresponding to the image displayed in the initial preview interface is 63 °; when the zoom magnification of the camera of the electronic device is 1×focal length corresponding to the camera is 2.8mm, and the field of view corresponding to the image displayed in the initial preview interface is 75 °.

In some embodiments of the present application, the "the zoom magnification corresponding to the image displayed in the initial preview interface is smaller than the first threshold" may indicate that: the electronic equipment has a relatively close object or a relatively large object to be shot, and the shooting requirement can be met by using a relatively small zoom ratio. Therefore, the electronic equipment does not need to use a larger zoom multiplying power, and the problem of focusing difficulty caused by the larger zoom multiplying power does not exist.

In some embodiments of the present application, the first threshold may be set by a user, or may be default to the electronic device, and embodiments of the present application are not limited in detail.

Step 112, receiving a fifth input from the user.

In some embodiments of the present application, the fifth input may be an input by which a user changes a zoom magnification.

Illustratively, the fifth input may be a two-finger zoom-in input to the initial preview interface by the user to increase the zoom magnification.

Illustratively, the fifth input may be a user input to a zoom magnification control displayed in the initial preview interface to select a desired zoom magnification.

Step 101a, in response to the fifth input, displaying a shooting preview interface in a case where the zoom magnification is greater than or equal to the first threshold.

In some embodiments of the present application, "the zoom magnification is greater than or equal to the first threshold" may be understood as: at this time, the object to be photographed by the electronic device is far away from the electronic device, or the electronic device needs to enlarge the object to be photographed, and at this time, the zoom magnification of the camera of the electronic device is large.

It will be appreciated that when the camera moves position with a large zoom magnification to capture other images, any slight movement of the electronic device will cause a large change in the object being captured. Therefore, the electronic equipment can display a shooting preview interface, and display a preview image acquired by a camera of the electronic equipment in an auxiliary preview window of the shooting preview interface, so that a user can directly select an object corresponding to a picture range to be shot from the preview image through a first mark, thereby avoiding the problem of difficult focusing caused by manual movement of the electronic equipment by the user, improving the focusing efficiency and accuracy of the electronic equipment under high zoom magnification, and further improving the efficiency of shooting images and videos.

Illustratively, taking the first threshold value as 10×as an example, when the zoom magnification of the camera of the electronic device reaches 10×, as shown in fig. 3A, the electronic device may display the preview image collected by the camera of the electronic device in the auxiliary preview window 31.

It should be noted that, the maximum zoom magnification of the camera of the electronic device may be greater than or equal to the first threshold, so as to trigger the electronic device to display the auxiliary preview window on the shooting preview interface.

Therefore, the electronic equipment can display the auxiliary preview window on the shooting preview interface when the zoom magnification of the camera is larger. Therefore, a user can directly select an object to be shot from the preview image displayed by the auxiliary preview window, so that the problem of focusing difficulty caused by manual movement of the electronic equipment by the user is avoided, and the efficiency of shooting images or videos by the electronic equipment under high-power zooming is improved.

The above embodiments of the method, or various possible implementation manners in the embodiments of the method, may be executed separately, or may be executed in any two or more combinations with each other, and may specifically be determined according to actual use requirements, which is not limited by the embodiments of the present application.

The photographing method provided by the embodiment of the present application is exemplarily described below with specific examples.

As shown in fig. 11, fig. 11 shows a flowchart of a photographing method according to an embodiment of the present application, which may be performed by an electronic device. As shown in fig. 11, the photographing method provided by the embodiment of the present application may include the following steps 201 to 205.

Step 201, displaying a main preview window and an auxiliary preview window on a shooting preview interface when the zoom magnification of the camera is greater than or equal to a first threshold.

The auxiliary preview window includes a first identifier, the first identifier indicates a first frame range, and the main preview window is used for displaying an image corresponding to the first frame range.

Step 202, detecting whether to enter a foot rest mode.

In some embodiments of the present application, the electronic device may normally anti-shake the photographed image without entering the stand mode.

Step 203, determining whether a first input of a user is received.

In some embodiments of the present application, the electronic device may control the lens of the camera to a central position without receiving the first input of the user, so that the user may change the photographed object by manually moving the electronic device.

Step 204, in case of receiving the first input of the user, updating the display position of the first identifier in the auxiliary preview window, and updating the image displayed in the main preview window.

Step 205, generating an image or video based on the image corresponding to the first picture range indicated by the first identifier.

Thus, the image displayed by the main preview window can be determined by the picture range indicated by the first mark in the auxiliary preview window in the shooting preview interface, so that the required image or video can be obtained. Therefore, the electronic equipment can change the image displayed by the main preview window by changing the picture range indicated by the first mark in the auxiliary preview window in the foot rest mode, and the user does not need to manually move the electronic equipment to aim at a shooting object to be shot, so that quick focusing can be realized, the operation is simple, and the efficiency of shooting images or videos is improved.
