Description

Shooting method and electronic equipment

Technical Field

The present application relates to the field of electronic technologies, and in particular, to a shooting method and an electronic device.

Background

With the development of technology, a shooting function has been popularized in electronic devices. When a user shoots a distant object using the electronic device, the shot image needs to be enlarged by zooming so as to make the shot object clearer.

However, in a shooting scene with a higher magnification, because the coverage area of the shot picture after being magnified is smaller, when the camera head of the electronic device shakes or the shooting object moves, the shooting object is easily lost by the user, and the shooting experience of the user is poor.

Disclosure of Invention

The application provides a shooting method and electronic equipment, which can improve shooting experience of a user during high-magnification amplification. In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a shooting method, which is applied to an electronic device including a camera, and includes: the electronic equipment receives and responds to a first operation to start a camera with a first zoom magnification and display a shooting interface which comprises a first view finder and a first preview image; the electronic equipment receives and responds to a second operation to adjust the camera to a second zoom magnification and the first preview image displayed in the first view frame is displayed in an enlarged mode to be a second preview image; the electronic device receives and adjusts the camera to a third zoom magnification in response to a third operation and displays a third preview image in the first view frame, and displays a second view frame within the first view frame. The first preview image is a framing picture under a first zoom magnification, the second preview image is a framing picture under a second zoom magnification, the third preview image is a framing picture under a preset zoom magnification, the fourth preview image is a framing picture under a third zoom magnification, the second zoom magnification is larger than the first zoom magnification and smaller than or equal to the preset zoom magnification, the third zoom magnification is larger than the preset zoom magnification, the second framing frame covers a partial area of the first framing frame, and the fourth preview image is displayed in the second framing frame.

It can be seen that, in the shooting method provided in the embodiment of the present application, the first view frame in the shot preview image is not continuously enlarged with the increase of the zoom magnification used by the electronic device by the user, but the preview image is displayed through the second view frame after the first view frame is enlarged to a certain magnification, that is, after the first view frame is larger than the preset zoom magnification. Therefore, when the lens shakes or the shooting object moves, the user can easily find the shooting object from the first view frame, and the shooting experience of the user in high-magnification amplification is improved.

Optionally, the preset zoom magnification may be a maximum optical zoom magnification of the camera. For example, if the maximum optical zoom magnification of the camera is 10 times, the preset zoom magnification is 10 times.

Optionally, the second preview image may be a portion of the first preview image.

Optionally, if the second zoom magnification is smaller than the preset zoom magnification, the third preview image is a part of the second preview image after being enlarged and displayed; and if the second zoom magnification is equal to the preset zoom magnification, the third preview image is the same as the second preview image.

In one possible implementation manner, after the second viewfinder frame is displayed in the first viewfinder frame, the method may further include: the electronic equipment receives a fourth operation, wherein the fourth operation is a shooting operation; and responding to the fourth operation, and shooting by the electronic equipment to obtain an image with the same content as the fourth preview image.

It can be seen that the final imaging obtained by shooting when the first finder frame and the second finder frame coexist in the shooting interface is the same image as the preview image content in the second finder frame.

In one possible implementation manner, after the second viewfinder is displayed in the first viewfinder, the method may further include: receiving a fifth operation of increasing the zoom magnification of the camera, which is input by a user; and responding to the fifth operation, increasing the zoom magnification of the camera, reducing the second view frame, and continuously displaying the third preview image in the first view frame.

In one possible implementation, after displaying the second viewfinder in the first viewfinder, the method further includes: receiving a sixth operation of reducing the zoom magnification of the camera input by a user; and responding to the sixth operation, reducing the zoom magnification of the camera, increasing the second view frame, and continuing to display the third preview image in the first view frame.

For example, when a user fixes a mobile phone by using a tripod or the like, the shooting angle of the mobile phone is already fixed, and if a shooting target moves, the user needs to move the mobile phone to track the shooting target, which is time-consuming and labor-consuming. In the embodiment of the application, as long as the shooting target is located in the first view finder, the user can easily track the shooting target only by moving the second view finder.

In one possible implementation manner, after the second viewfinder is displayed in the first viewfinder, the method further includes: receiving an eighth operation of starting object tracking input by a user; in response to the eighth operation, moving the second finder frame following the object within the second finder frame.

It can be seen that the user can follow track shooting to the shooting object through operation instruction electronic equipment, and when this shooting object moved promptly, the second frame of finding a view was followed this shooting object and is moved, keeps this shooting object in the second frame of finding a view promptly all the time to prevent that the shooting object from losing the shooting object because of moving, further promoted user's shooting experience.

In one possible implementation, after displaying the second viewfinder in the first viewfinder, the method further includes: and reducing the brightness of a target area of the first view frame, wherein the target area of the first view frame is an area which is not overlapped with the second view frame in the first view frame.

In yet another possible implementation manner, after the second viewfinder is displayed in the first viewfinder, the method further includes: and overlaying a layer on the target area of the first view frame.

Under the condition that the shooting interface has the first view frame and the second view frame, the target area of the first view frame is subjected to image processing, so that a user can distinguish the target area of the first view frame from the second view frame conveniently, and the shooting experience of the user is further improved.

In the shooting process introduced in the embodiment of the present application, a user opens a camera application, starts the camera application on the application layer in fig. 2, and sends an instruction to the kernel layer to invoke a camera driver, a sensor driver, and a display driver on the kernel layer, so that the electronic device can start a camera or a lens to acquire an image. In the process of collecting images by the camera, light is transmitted to the image sensor through the camera, and the image sensor performs photoelectric conversion on light signals and converts the light signals into images visible to naked eyes of a user. The output image data is transmitted to the system library in fig. 2 in a data stream form, and the three-dimensional graphic processing library and the image processing library realize drawing, image rendering, synthesis, layer processing and the like to generate a display layer; and the surface manager performs fusion processing and the like on the display layer, transmits the fusion processing and the like to a content provider, a window manager and a view system of the application program framework layer, and controls the display of the display interface. Finally, the preview image is displayed on an image preview area of the camera application or a display screen of the electronic device.

For convenience of understanding, the following embodiments of the present application will describe a photographing process of an electronic device by taking the electronic device having the structure shown in fig. 1 and 2 as an example.

The technical solutions in the following embodiments can be implemented in the electronic device 100 having the above hardware architecture and software architecture.

In the embodiment of the present application, the electronic device 100 is a mobile phone as an example, and technical solutions provided in the embodiment of the present application are described in detail with reference to the drawings.

Fig. 3 is a schematic diagram of a Graphical User Interface (GUI) provided in an embodiment of the present application, where (a) in fig. 3 illustrates that, in an unlocking mode of a mobile phone, a screen display system of the mobile phone displays currently output interface content 301, where the interface content 301 is a main interface of the mobile phone. The interface content 301 shows a plurality of applications (apps), such as applications like cameras, address books, telephones, information, clocks, etc. It should be noted that the interface content 401 may also include other more application programs, which is not limited in this embodiment of the application.

The user can instruct the mobile phone to start the camera application by touching a specific control on the mobile phone screen, pressing a specific physical key or key combination, inputting voice, separating air gestures, and the like. And after the instruction of opening the camera by the user is received, starting the camera by the mobile phone and displaying a shooting interface.

Illustratively, as shown in fig. 3 (a), the user may instruct the cell phone to open the camera application by clicking a "camera" application icon on the main interface, and the cell phone displays a shooting interface as shown in fig. 3 (b).

Further exemplarily, when the mobile phone is in the screen-locked state, the user may also instruct the mobile phone to start the camera application through a gesture of sliding rightward on the screen of the mobile phone, and the mobile phone may also display the shooting interface as shown in fig. 3 (b). Or, when the mobile phone is in the screen lock state, the user may instruct the mobile phone to start the camera application by clicking the shortcut icon of the "camera" application on the screen lock interface, and the mobile phone may also display the shooting interface shown in fig. 3 (b).

Further exemplarily, when the mobile phone runs other applications, the user may also enable the mobile phone to open the camera application for taking a picture by clicking the corresponding control. For example, when the user is using an instant messaging application, the user may also instruct the mobile phone to start the camera application by selecting a control of the camera function, and the mobile phone displays a shooting interface as shown in fig. 3 (b).

As shown in fig. 3 (b), the camera interface generally includes a first view finder 302, a shooting control, and other functional controls ("aperture", "night scene", "portrait", "photograph", "video", "professional", etc.). The first view frame 302 can be used to preview an image (or picture) captured by the camera, and the first view frame 302 shown in fig. 3 (b) can be used to preview people, kites, buildings, and clouds captured by the camera. The user can decide the timing to instruct the cellular phone to perform the photographing operation based on the image (or screen) in the first finder frame 302. The user may instruct the mobile phone to perform the shooting operation, for example, the user may click a shooting control, or the user presses a volume key, or the mobile phone is controlled by a voice instruction to perform shooting.

In some embodiments, a zoom magnification indication 303 may also be included in the capture interface. In general, the default zoom magnification of the mobile phone is the basic magnification, which may also be referred to as the first zoom magnification, "1 ×", that is, no zooming is performed. The user can change the zoom ratio by touching a specific control on the screen of the mobile phone, pressing a specific physical key or key combination, inputting voice, separating gestures and the like.

Illustratively, as shown in fig. 3 (b), the user can adjust the zoom magnification used by the mobile phone by operating a zoom magnification instruction 303 in the shooting interface. For example, when the zoom magnification used by the mobile phone is "1 ×", the user can change the zoom magnification used by the mobile phone to another zoom magnification (e.g., "5 ×", "10 ×", "20 ×", "50 ×" etc.) by clicking the zoom magnification indication 303 one or more times. Here, "5 ×" means a zoom magnification of 5 times, that is, a zoom magnification of 5 times when zooming is not performed; "10 ×" means a zoom magnification of 10 times, that is, a zoom magnification of 10 times when zooming is not performed; "20 ×" means a zoom magnification of 20 times, that is, 20 times when zooming is not performed, and "50 ×" means a zoom magnification of 50 times, that is, 50 times when zooming is not performed.

Further illustratively, as shown in fig. 3 (c), the user may increase the zoom magnification used by the mobile phone by a gesture of sliding two fingers (or three fingers) outward (in the opposite direction to the pinch) in the photographing interface, or decrease the zoom magnification used by the mobile phone by a gesture of pinching two fingers (or three fingers).

Further exemplarily, as shown in fig. 3 (d), the user may also change the zoom magnification used by the mobile phone by dragging the zoom scale 304 in the shooting interface.

As shown in fig. 4 (a), when the zoom magnification used by the mobile phone is "1 ×", that is, when zooming is not performed, the user can see the entire view of the building, the white clouds, the people, and the kite through the preview image of the first finder frame 302 in the camera interface of the mobile phone,

as shown in fig. 4 (b), when the user increases the zoom ratio used by the mobile phone from "1 ×" to "5 ×", the preview image of the first finder frame 302 in the camera interface of the mobile phone is enlarged with the center as the origin, the object in the first finder frame is enlarged accordingly, and the finder range of the first finder frame is reduced accordingly. When the zoom ratio used by the mobile phone is "5 ×", the user can only see a part of the building after being enlarged through the preview image of the first finder frame 302 in the shooting interface of the mobile phone, the size of the clouds, people and kite in the preview image is increased relative to the size in the preview image in (a) in fig. 4, but the clouds are also closer to the edge of the first finder frame due to the reduction of the view range.

As shown in fig. 4 (c), when the zoom ratio used in the mobile phone is "10 ×", the object in the first finder frame is enlarged, and the range of view of the first finder frame is reduced. Due to the reduction of the viewing range, the user cannot see the buildings in the first viewing frame 302 through the preview image of the first viewing frame 302 in the shooting interface of the mobile phone, and the number of the visible white clouds is reduced from 5 to 2.

As can be seen from (a), (b), and (c) in fig. 4, the preview image in the first finder frame can be enlarged with the center as the origin by increasing the zoom (magnification) used by the mobile phone, but the viewing range of the finder frame is also reduced. It can be understood that, in a shooting scene with a higher magnification, since the coverage area (viewing range) of the enlarged shooting picture is smaller, when the lens shakes or the shooting object moves, the shooting object is easily lost by the user, and the shooting experience of the user is poor.

Referring to fig. 4 (c), as shown in fig. 4 (d), in the embodiment of the present application, when the user increases the zoom magnification used by the mobile phone so that the zoom magnification used by the mobile phone is greater than the preset zoom magnification (for example, "10 ×"), the preview image of the first finder frame 302 in the shooting interface of the mobile phone is maintained to be no longer enlarged and the second finder frame 305 is displayed in the preview image of the first finder frame.

The preset zoom magnification may be a maximum magnification of the optical zoom of the mobile phone, and may also be referred to as a maximum optical zoom magnification. The picture shot when the zoom magnification is larger than the preset zoom magnification is obtained by processing the picture shot under the preset zoom magnification. For example, if the maximum magnification of the optical zoom of the mobile phone is "10 ×", the preset zoom magnification may be "10 ×". Then the picture taken by the mobile phone with the magnification of more than 10 x is obtained by clipping and post-processing (processing operations such as point filling and image coding) the picture taken with the magnification of 10 x.

For another example, if the maximum magnification of the optical zoom of the mobile phone is "5 ×", the preset zoom magnification may be "5 ×".

Then the picture taken by the phone at a magnification of greater than "5 x" is obtained by cropping and post-processing the picture taken at "5 x" magnification.

It should be noted that, if the preset zoom magnification is the maximum magnification of the optical zoom of the mobile phone, the shooting process in which the zoom magnification used by the mobile phone is less than or equal to the preset zoom magnification may be referred to as an optical zoom shooting process; the shooting process in which the zoom magnification used by the mobile phone is greater than the preset zoom magnification can be referred to as a digital zoom shooting process.

It can be seen that, in the shooting method provided in the embodiment of the present application, the shot preview image (the first view frame) is not continuously enlarged with the increase of the zoom magnification used by the electronic device by the user, but the preview image is displayed through the second view frame after the shot preview image is enlarged to a certain magnification. Therefore, when the lens shakes or the shooting object moves, the user can easily find the shooting object from the first view frame, and the shooting experience of the user in high-magnification amplification is improved.

It should be noted that the size of the second finder frame may be decreased as the zoom ratio is increased. As shown in fig. 4 (d) and (e), the user increases the zoom magnification used by the mobile phone from "20 ×" to "50 ×", and the size of the second finder frame 305 decreases accordingly.

The size of the second finder frame 305 may be increased as the zoom magnification is decreased. As shown in fig. 4 (e) and (f), the user decreases the zoom magnification used by the mobile phone from "50 ×" to "20 ×", and the size of the second finder frame 305 increases accordingly.

It should be noted that, in the embodiment of the present application, when the zoom magnification used by the mobile phone is greater than the preset zoom magnification (i.e., the mobile phone is in the digital zoom photographing stage), the range of the image photographed by the mobile phone is no longer what is seen or what is obtained, i.e., the photographed image is no longer the first view frame 302 but the second view frame 305. In other words, when the zoom magnification used by the mobile phone is larger than the preset zoom magnification, the user does not need to decide the timing to instruct the mobile phone to perform the photographing operation based on the first finder frame 302, but decides the timing to instruct the mobile phone to perform the photographing operation based on the image (or screen) of the second finder frame 305. As shown in fig. 5 (a), when the zoom magnification (10 ×) used by the mobile phone is not greater than the preset zoom magnification (i.e., the mobile phone is in the optical zoom photographing stage), the image (final image) photographed by the mobile phone is the same as the screen of the first finder frame 302. As shown in (b) and (c) of fig. 5, when the zoom magnification (20 × or 50 ×) used by the mobile phone is larger than the preset zoom magnification, the image captured by the mobile phone is no longer the same as the screen of the first finder frame 302 but is the same as the screen of the second finder frame 305.

In some embodiments, the user may change the position of the second finder frame in the first finder frame to adjust the captured picture of the second finder frame. For example, the user may change the position of the second viewfinder in the first viewfinder by touching a particular control on the cell phone screen, pressing a particular physical key or combination of keys, inputting speech, air gesture, etc.

For example, as shown in fig. 6 (a), the user may adjust the photographed picture in the second finder frame 305 from "person" to "kite" by dragging the second finder frame 305 to move in the first finder frame 302.

It can be seen that, in the shooting method provided by the embodiment of the application, the user can change the shooting picture of the second view finder through multiple modes, and compared with the design that the existing shooting method only can use the center of the view finder as a shooting point, the shooting method has greater elasticity for imaging, and further improves the shooting experience of the user. For example, when a user fixes a mobile phone by using a tripod or the like, the shooting angle of the mobile phone is already fixed, and if a shooting target moves, the user needs to move the mobile phone to track the shooting target, which is time-consuming and labor-consuming. In the embodiment of the application, as long as the shooting target is located in the first view finder, the user can easily track the shooting target only by moving the second view finder.

In some embodiments, in the case where the first view frame 302 and the second view frame 305 coexist in the shooting interface, the target area of the first view frame may be subjected to image processing, which facilitates the user to distinguish the target area of the first view frame from the second view frame. The target area of the first view frame is an area which is not overlapped with the second view frame in the first view frame.

For example, as shown in (b) of fig. 6, in the case where the first finder frame 302 and the second finder frame 305 coexist in the photographing interface, the brightness of the target area of the first finder frame 302 may be reduced so that the user can distinguish the target area of the first finder frame 302 and the second finder frame 305 by the brightness.

Further exemplarily, as shown in fig. 6 (c), in a case where the first view frame 302 and the second view frame 305 coexist in the photographing interface, the target area of the first view frame may be blurred so that the user distinguishes the target area of the first view frame 302 and the second view frame 305 by sharpness.

Further exemplarily, in a case where the first view frame 302 and the second view frame 305 coexist in the shooting interface, a target area of the first view frame 302 may be subjected to layer processing, for example, one layer is covered on the target area, so that a user can distinguish the target area of the first view frame 302 from the second view frame 305.

In some embodiments, the mobile phone may perform tracking shooting on the shooting object in the second finder frame 305. For example, the user may instruct the mobile phone to perform tracking shooting on the shooting object in the second finder frame 305 by touching a specific control on the mobile phone screen, pressing a specific physical key or key combination, inputting voice, and performing a blank gesture, where when the shooting object moves, the second finder frame 305 moves along with the shooting object, that is, the shooting object is always kept in the second finder frame 305.

Illustratively, as shown in fig. 7 (a), the "kite" is located in the second finder frame 305, the following control 306 is included beside the second finder frame 305, the following control 306 displays "off" to indicate that the tracking shot is not currently turned on, and the following control 306 displays "on" to indicate that the tracking shot is currently turned on. As shown in (a) and (b) of fig. 7, when the following control 306 displays "close", the user instructs the mobile phone to track and shoot a "kite" in the second finder frame by clicking the following control 306, the "kite" flies from the right side to the left side, and the mobile phone follows the "kite" in the second finder frame 305, so that the second finder frame 305 also moves from the right side to the left side.

Further illustratively, the second finder frame 305 includes a following control 306, the following control 306 displays "close" to indicate that the tracking shooting is currently started, and the user can instruct the mobile phone to stop the tracking shooting of the object in the second finder frame by clicking the following control 306 when the following control 306 displays "close". The follow control 306 displays "on" indicating that the tracking shot is not currently on. The user can instruct the mobile phone to start tracking and shooting the object in the second view finder by clicking the following control 306 when the following control 306 displays "on".

Further illustratively, the mobile phone may automatically turn on the tracking shot when a preset condition is satisfied. For example, when there is an object in the second finder frame 305 and the second finder frame 305 has not moved for a certain period of time, the cellular phone may start tracking shooting to follow the object in the second finder frame 305.

The above-mentioned specific method for performing tracking shooting on the shooting object in the second view finder may be processed by any method that can be thought by those skilled in the art, and this is not particularly limited in this embodiment of the application.

In some embodiments, the mobile phone may stop the tracking shooting of the photographic subject in the second finder frame. For example, the user may instruct the mobile phone to stop tracking shooting the shooting object in the second viewfinder by touching a specific control on the mobile phone screen, pressing a specific physical key or key combination, inputting voice, and/or a blank gesture. For example, as shown in fig. 7 (b), the user may instruct the mobile phone to stop tracking shooting the "kite" in the second finder frame by clicking the following control 306 beside the second finder frame 305 while the following control 306 displays "on"; after the user clicks the follow-up control 306 and stops the tracking shooting of the object in the second finder frame, the follow-up control 306 may be displayed as "off" as shown in fig. 7 (a).

The digital zoom photographing process of the photographing method provided by the embodiment of the present application, that is, the photographing process in which the first view frame 302 and the second view frame 305 coexist in the photographing interface, as shown in fig. 8, is described below with reference to fig. 8, and the process includes:

s801, the mobile phone records the coordinates of the four corners of the second finder frame 305.

The four-corner coordinates of the second finder frame 305 are the four-corner coordinates of the second finder frame 305 in the target coordinate system. Alternatively, the target coordinate system may be a coordinate system with an arbitrary point (e.g., a vertex, a center point, etc.) in the first viewfinder 302 as a coordinate origin.

Illustratively, as shown in fig. 9 (a), the target coordinate system is a coordinate system having a lower left vertex of the first finder frame 302 as a coordinate origin. It can be seen that the four corner coordinates of the second finder frame 305 are (X1, Y1), (X2, Y2), (X3, Y3), and (X4, Y4), respectively.

S802, mobile phone response operation.

If the operation is a zoom operation, the mobile phone executes S803.

If the operation is an operation of dragging the second finder frame, the mobile phone executes S804.

If the operation is a tracking shooting operation, the mobile phone executes S805.

If the operation is a photographing operation, the mobile phone performs S806.

S803, if the zooming operation is to increase the focal length, the mobile phone reduces the second view finder by taking the center of the second view finder as the origin, and then S801 is executed; if the zoom operation is to reduce the focal length, the mobile phone increases the second finder frame with the center of the second finder frame as the origin, and then executes S801. It should be noted that, if the zoom operation is to zoom out, when the zoom magnification is reduced to the preset zoom magnification, the size of the second finder frame 305 is the same as the size of the first finder frame 302, and the second finder frame 305 may not be displayed any more, that is, when the zoom magnification is reduced to the preset zoom magnification, the second finder frame 305 is stopped being displayed in the first finder frame 302.

S804, the mobile phone moves the second finder frame according to the operation, and then executes S801.

S805, the mobile phone moves the second finder frame following the object in the second finder frame, and then S801 is executed.

And S806, performing imaging cutting and post-processing by the mobile phone according to the coordinates of the four corners of the current second viewing frame to obtain final imaging.

The specific method for obtaining the final image by the post-processing may be any method that can be conceived by those skilled in the art, and this is not particularly limited in the embodiment of the present application. For example, the mobile phone may perform the complement optimization on the image obtained by the imaging clipping, and then perform the image coding on the image after the complement optimization to obtain the final imaging.

Illustratively, as shown in fig. 9 (a) and (b), the mobile phone performs image cropping and post-processing according to the four-corner coordinates of the second viewfinder frame shown in fig. 9 (a) in response to the user's photographing operation to obtain a first image 307 shown in fig. 9 (b).

The shooting method provided by the embodiment of the present application is described below with reference to fig. 10, and as shown in fig. 10, the method includes:

s1001, the electronic equipment receives a first operation, responds to the first operation, starts the camera and displays a shooting interface.

The zoom magnification of the camera is a first zoom magnification, the shooting interface comprises a first view frame, the first view frame comprises a first preview image, and the first preview image is a view frame under the first zoom magnification. The first preview image is a framing picture under a first zoom magnification, and the method comprises the following steps: when shooting is carried out under the first zoom magnification, the image shot by the camera is the same as the framing picture, namely the shot image is the same as the first preview image.

The first zoom magnification is usually a magnification at which the camera is not zoomed, and the first zoom magnification may be represented by "1 ×".

Illustratively, as shown in fig. 3 (a), the electronic device receives and responds to the operation of clicking a camera application icon on a main interface of the electronic device by a user, opens a camera application, and displays a shooting interface as shown in fig. 3 (b). As shown in fig. 3 (b), the shooting interface includes a first finder frame 302, the first finder frame 302 includes a first preview image, and the first preview image is a finder screen with a zoom magnification of "1 ×" of the camera.

And S1002, the electronic equipment receives a second operation, and in response to the second operation, the camera is adjusted to a second zoom magnification, and the first preview image displayed in the first view frame is displayed in an enlarged mode to be a second preview image.

The second zoom magnification is greater than the first zoom magnification, the second zoom magnification is less than or equal to the preset zoom magnification, the second preview image is a viewing frame under the second zoom magnification, and the second preview image can be a part of the first preview image. The second preview image is a framing picture at a second zoom magnification, and the method comprises the following steps: when shooting is carried out under the second zoom magnification, the image shot by the camera is the same as the view-finding picture, namely the shot image is the same as the second preview image.

Alternatively, the preset zoom magnification may be a maximum optical zoom magnification of the camera. For example, if the maximum optical zoom magnification of the camera is 10 times, the preset zoom magnification is 10 times.

Illustratively, as shown in fig. 4 (a) and (b), the electronic apparatus receives and responds to a zoom operation in which the user adjusts the zoom magnification from "1 ×" to "5 ×" in the shooting interface, adjusts the zoom magnification of the camera from "1 ×" to "5 ×" and displays the first preview image displayed in the first finder frame 302 as shown in fig. 4 (b) as a second preview image, which can be seen as a part of the first preview image by fig. 4 (a) and (b).

S1003, the electronic equipment receives a third operation, responds to the third operation, adjusts the camera to be at a third zoom magnification, displays a third preview image in the first view frame, and displays a second view frame in the first view frame.

And the third zoom magnification is greater than the preset zoom magnification, the second viewing frame covers a partial area of the first viewing frame, and the fourth preview image is displayed in the second viewing frame. The third preview image is a framing picture under a preset zoom magnification, and the fourth preview image is a framing picture under the third zoom magnification. The third preview image is a view-finding picture under a preset zoom magnification, which means that: when shooting is carried out under the preset zoom magnification, the image shot by the camera is the same as the third preview image. The fourth preview image is a framing picture at the third zoom magnification, and the method comprises the following steps: when shooting is carried out under the third zoom magnification, the image shot by the camera is the same as the fourth preview image.

Illustratively, as shown in (b), (c), and (d) in fig. 4, the electronic apparatus receives and responds to a zoom operation in which the user adjusts the zoom magnification from "5 ×" to "20 ×" in the shooting interface, and displays a third preview image at the camera zoom magnification of "10 ×" in the first finder frame 302, displays the second finder frame 305 within the first finder frame 302, and displays a finder screen at the camera zoom magnification of "20 ×" in the second finder frame 305 as shown in (d) in fig. 4.

It can be understood that, if the second zoom magnification is smaller than the preset zoom magnification, the third preview image is a portion of the second preview image after being displayed in an enlarged manner. For example, as shown in (b) and (d) of fig. 4, the corresponding second zoom magnification "5 ×" of (b) of fig. 4 is smaller than the preset zoom magnification "10 ×", and it can be seen that the third preview image shown in (d) of fig. 4 is a portion of the enlarged display of the second preview image shown in (b) of fig. 4.

And if the second zoom magnification is equal to the preset zoom magnification, the third preview image is the same as the second preview image. For example, as shown in (c) and (d) of fig. 4, the second zoom magnification "10 x" corresponding to (c) of fig. 4 is equal to the preset zoom magnification "10 x", and it can be seen that the third preview image shown in (d) of fig. 4 is the same as the second preview image shown in (c) of fig. 4.

In one possible implementation, after displaying the second view frame in the first view frame, the method may further include: the brightness of the target area of the first finder frame is reduced as shown in fig. 6 (b). The target area of the first view frame is an area which is not overlapped with the second view frame in the first view frame.

In another possible implementation manner, after displaying the second view frame in the first view frame, the method may further include: the target area of the first finder frame is subjected to blurring processing as shown in (c) of fig. 6.

In yet another possible implementation manner, after displaying the second frame in the first frame, the method may further include: and overlaying a layer on the target area of the first view frame.

As shown in fig. 10, optionally, after S1003, the embodiment of the present application may further include one or more of the following steps: s1004, S1005, S1006, S1007, or S1008. The steps S1004, S1005, S1006, S1007, and S1008 may be parallel, or may have a certain sequence according to actual conditions. For example: after S1004, S1005, or S1006, or 1007 may be performed; alternatively, after S1005, S1004 or S1006 or 1007 may be performed; alternatively, after S1006, S1004 or S1005 or 1007 or S1008 may be performed; alternatively, after S1007, S1004 or S1005 or 1006 or S1008 may be performed.

And S1004, the electronic equipment receives a fifth operation of increasing the zoom magnification of the camera, responds to the fifth operation, increases the zoom magnification of the camera, reduces the second view frame, and continues to display the third preview image in the first view frame.
