Shooting method and equipment

Technical Field

The embodiment of the application relates to the technical field of electronics, in particular to a shooting method and equipment.

Background

With the development of electronic technology, more and more cameras are integrated on electronic equipment. The plurality of cameras may include cameras of multiple focal segments, such as may include short-focus wide-angle cameras, medium-focus cameras, and long-focus cameras. The cameras of different focal lengths can correspond to different viewing ranges and zoom magnifications, so that shooting scenes of the electronic equipment can be enriched.

When the user switches the zoom magnification, the camera used by the electronic device for shooting may also be switched accordingly. For example, when the zoom ratio is switched to the large zoom ratio, the electronic device may switch from the wide camera or the mid-focus camera to the telephoto camera, so as to display a preview picture of the telephoto camera and perform shooting with the telephoto camera.

After the wide-angle camera or the middle-focus camera is switched to the long-focus camera, the view finding range is reduced, and a target object to be photographed easily runs out of a preview picture of the long-focus camera. That is, the electronic apparatus easily loses the target object to be photographed. In the case of previewing using a telephoto camera, it often takes a long time for a user to find a target object.

Disclosure of Invention

The embodiment of the application provides a shooting method and shooting equipment, which can guide a user to move electronic equipment according to a target object, so that the electronic equipment can adopt a long-focus camera to quickly lock the target object, the time for the user to search for the target object is saved, and the use experience of the user is improved.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in one aspect, an embodiment of the present application provides a shooting method, including: the electronic device starts the camera. And then, the electronic equipment adopts the first camera and the second camera to respectively acquire the first preview image and the second preview image. The second camera is a long-focus camera, and the view range of the first camera is larger than that of the second camera. The electronic device displays a first preview interface. The first preview interface includes a first view frame, a second view frame, and a third view frame. The first viewfinder is used for displaying a first preview image. The image in the second viewing frame is a part of the first preview image; and the content in the second viewing frame is a target object to be shot by the second camera. The third viewing frame is used for displaying the second preview image. The electronic equipment displays first prompt information, and the first prompt information is used for guiding a user to move the electronic equipment, so that the target object can be locked by the second camera after the electronic equipment moves.

Therefore, after the electronic equipment is switched from a first camera such as a wide-angle camera or a medium-focus camera to a long-focus camera such as a second camera, the electronic equipment can guide a user to move the electronic equipment through the prompt information. So that the tele camera can quickly lock onto the target object after the electronic device is moved. Further, the electronic device may capture an image of the target object using a tele camera.

In one possible design, after the electronic device displays the first preview interface, the method further includes: the electronic device detects a drag operation of the user for the second finder frame. The electronic device moves the second finder frame on the first preview image in response to the drag operation, the target object changing as the position of the second finder frame changes.

That is, the user can specify and change the target object by dragging the position of the second finder frame.

In another possible design, the method further includes: when the second view frame is close to the third view frame, the electronic equipment moves the third view frame away to avoid the second view frame.

Therefore, the second view frame and the third view frame do not overlap, and the user can visually and clearly see the contents in the two view frames.

In another possible implementation, the first prompt information is used for indicating the moving direction and the moving distance of the electronic equipment.

That is, the electronic device may prompt the user of the direction and the movement amplitude of the mobile electronic device through the first prompt message.

After the electronic device is moved in the direction indicated by the arrow, the length of the arrow becomes shorter.

That is, the arrow may serve as the first prompt message, and may dynamically indicate whether the user moves the electronic device, the size of the movement distance, and whether the movement direction is correct.

In another possible design, the first prompt message may also indicate a flip direction of the electronic device, and a flip angle.

Therefore, the first prompt message can prompt the user of the direction and the amplitude of the electronic equipment to move and also prompt the user of the direction and the amplitude of the electronic equipment to turn over.

In another possible design, the smaller the size of the second view frame, the larger the zoom magnification of the second preview image in the third view frame; the larger the size of the second finder frame is, the smaller the zoom magnification of the second preview image in the third finder frame is.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

The view finding range of the long-focus camera is small, the size of an object on an image shot by the long-focus camera is large, and the long-focus camera can be suitable for shooting a distant object, a close-up scene, object details or shooting a certain small object specially. The wide-angle camera and the middle-focus camera have larger viewing range and can shoot objects and pictures in a larger range.

When other cameras such as a wide-angle camera or a mid-focus camera are switched to a telephoto camera for shooting, the electronic device is prone to lose a target object to be shot. That is, it is difficult for the electronic device to lock the target object by the long focus camera. The user cannot see the target object on the preview interface of the tele-camera. In the prior art, after the target object is lost, the user does not know the specific position of the target object, so that the user usually searches heuristically around blindly in hope of finding the target object. Moreover, because the view range (or the range of view angle that can be shot) of the telephoto camera is small, and the target object is usually far away from the user, the user is likely to miss the target object during searching. Therefore, the user often takes much time and effort, and it is difficult to search for the target object.

The embodiment of the application provides a shooting method which can be applied to electronic equipment. For example, the electronic device may specifically be a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or a specialized camera (e.g., a single lens reflex camera, a card camera), and the like, and the specific type of the electronic device is not limited in this embodiment of the application.

In the embodiment of the application, the user can specify the target object in the shooting scene. After the electronic equipment is switched to the tele camera by other cameras such as the wide-angle camera or the mid-focus camera, the electronic equipment can guide the user to move the electronic equipment according to a target object specified by the user. The user can move the electronic equipment according to the guide, so that the back long-focus camera of the mobile electronic equipment can quickly lock the target object. Further, the electronic device may capture an image of the target object using a tele camera.

So that the electronic apparatus 100 can quickly lock the target object through the telephoto camera after moving, thereby performing image photographing.

The shooting method provided by the embodiment of the present application will be explained below by taking the electronic device with the structure shown in fig. 1A as a mobile phone, and taking the mobile phone as an example, where the mobile phone includes a touch screen. As above, the touch screen may include a display panel and a touch panel. The display panel may display an interface. The touch panel can detect the touch operation of a user and report the touch operation to the mobile phone processor for corresponding processing.

In some embodiments, when the user uses the mobile phone to capture an image, the user may instruct the mobile phone to start the camera by a touch operation, a key operation, a gesture operation in the air, or a voice operation. Illustratively, as shown in (a) of fig. 2A, the mobile phone starts a camera function after detecting an operation of clicking a camera icon 201 by a user.

In some embodiments, after the camera is started, the mobile phone may automatically enter a shooting mode such as a shooting mode, a video recording mode, or a tele auxiliary mode, and display a preview interface.

For example, the mobile phone may automatically enter the photographing mode after detecting an operation of clicking the camera icon 201 shown in (a) of fig. 2A by the user. In one example, the handset may display a preview interface 202 as shown in (b) of fig. 2A. In another example, a preview interface is displayed as shown in FIG. 2B. The preview interface shown in fig. 2A or fig. 2B includes a view box. The preview image collected by the default camera can be displayed in the view-finding frame. For example, the default camera may be a wide-angle camera.

After the mobile phone starts the camera, if the mobile phone does not enter the tele auxiliary mode, the mobile phone can enter the tele auxiliary mode according to the instruction of the user; or, the mobile phone can automatically enter the tele auxiliary mode according to the zoom magnification.

For example, on the preview interface 202 shown in (b) in fig. 2A, if the mobile phone detects an operation of clicking the control 203 by the user, the tele-assist mode may be entered.

As still another example, referring to (c) in fig. 2A, the mobile phone detects that the user is on the preview interface 202, and indicates an operation of increasing the zoom magnification. For example, the operation indicating to increase the zoom magnification may be an operation in which the user drags the zoom scale 204 on the preview interface 202, or an operation in which the user's finger performs the reverse of the pinch-in on the preview interface 202. If the increased zoom magnification is greater than or equal to the preset value 3 (for example, 5 times), the mobile phone may automatically enter the tele auxiliary mode.

As another example, on the preview interface in the photographing mode shown in (a) in fig. 3, if the mobile phone detects an operation of clicking the control 301 by the user, a setting interface shown in (c) in fig. 3 may be displayed. Alternatively, on the preview interface shown in (b) in fig. 3, if the mobile phone detects an operation of clicking the control 302 by the user, a setting interface as shown in (c) in fig. 3 may be displayed. Then, if the mobile phone detects that the user clicks the control 303, the tele-assist mode is entered.

As another example, in the photographing mode, a preview interface displayed by the mobile phone may include a camera identifier. After detecting the operation of selecting the identification of the long-focus camera by the user, the mobile phone determines that the user selects the long-focus camera to shoot the image, and then enters a long-focus auxiliary mode. For example, referring to fig. 4A, the preview interface of the mobile phone includes a rear wide-angle camera identifier 401, a rear middle-angle camera identifier 402, a rear tele-camera identifier 403, and the like. And when the mobile phone detects that the user clicks the mark 403, entering a long-focus auxiliary mode.

As another example, in the photographing mode, the mobile phone may prompt the user whether to enter the tele-assist mode. Or, in the photographing mode, after the mobile phone determines that the user selects the tele camera to photograph the image, the mobile phone may prompt the user whether to enter the tele auxiliary mode. For example, referring to fig. 4B, the cell phone may display information 405 to prompt the user; after detecting the operation of clicking the control 406 by the user, the mobile phone enters a tele-assisted mode.

For another example, in the photographing mode or the video recording mode, after detecting that the user draws a preset track 1 (for example, an "F" track) on the touch screen, the mobile phone enters the tele assist mode.

In other embodiments, when the mobile phone displays a desktop or displays an interface of another application, and the user wants to use the tele-assist mode of the mobile phone, the mobile phone may start the camera function and directly enter the tele-assist mode according to an instruction of the user, such as a touch operation, an air gesture operation, a voice operation, or a key operation.

For example, when the mobile phone displays a desktop or displays an interface of another application, if an instruction that the user indicates to enter the tele auxiliary mode is received, the camera is started and the tele auxiliary mode is entered. As another example, in the case of bright screen and displaying the desktop, or in the case of black screen as shown in fig. 4C, if the mobile phone detects that the user draws a preset track 2 (for example, a "CF" track) on the touch screen, the camera is started and the tele-assist mode is entered.

The above-described manner of entering the tele auxiliary mode is only an exemplary illustration, and the mobile phone may also enter the tele auxiliary mode through other manners, which is not limited in this embodiment of the application.

After entering the long-focus auxiliary mode, the mobile phone starts the auxiliary camera and the long-focus camera. The mobile phone can display a tele auxiliary preview interface. As shown in fig. 5A or 5B, the tele-assistant preview interface 501 may include an assistant view frame 502 and a target view frame 503. In some embodiments, as shown in fig. 5C or 5D, tele-assisted preview interface 501 may also include a live view box 504.

The auxiliary view frame 502 may be used to display a preview image captured by the auxiliary camera, where the preview image is also called an auxiliary preview image. The auxiliary camera may be a default camera or a camera designated by a user. The auxiliary camera can be a wide-angle camera or a middle-focus camera with a view finding range larger than that of the long-focus camera. In some embodiments, the assistant view box 502 may be spread over the entire display area, i.e., the cell phone may display the assistant preview image full screen.

Illustratively, the auxiliary camera is a wide-angle camera. The auxiliary preview image captured by the wide-angle camera is displayed in the auxiliary view frame 502 shown in fig. 5C. After detecting that the user clicks the control 505, the mobile phone may switch the auxiliary camera to a middle-focus camera, and an auxiliary preview image acquired by the middle-focus camera is displayed in the auxiliary view-finding frame 502.

The zoom magnification of the auxiliary preview image in the auxiliary view frame 502 may be changed accordingly according to the user's instruction. For example, referring to fig. 5E, after the mobile phone detects an operation of dragging the zoom scale 506 by the user, the zoom magnification of the auxiliary preview image in the auxiliary view frame 502 may be adjusted.

The target finder frame 503 may be used to display a target object to be photographed by the telephoto camera, which is designated by the user on the auxiliary preview image. That is, the content in the target finder frame 503 is a target object specified by the user. In some embodiments, a prompt message may be displayed near the target viewfinder 503, or the handset may play a voice message to prompt the user for the viewfinder to frame the target object.

The image in the target finder frame 503 is a portion selected on the auxiliary preview image. The image size displayed in the target finder frame 503 matches the image size on the auxiliary preview image. When the auxiliary preview image in the auxiliary view frame 502 changes after the user designates the target object, the target view frame 503 moves as the position of the target object on the auxiliary preview image moves. When the zoom magnification of the image in the auxiliary view frame 502 is changed, the size of the image displayed in the auxiliary view frame 502 is also changed accordingly, and the size of the image displayed in the target view frame 503 is also changed accordingly.

Illustratively, the zoom magnification of the auxiliary preview image corresponding to fig. 5E is larger than that of fig. 5C, and the image size of the target object in the target finder frame 503 is also larger.

In some embodiments, upon entering the tele-preview aided mode, the target viewing frame 503 may be located in the center area of the preview aided image by default, or in a position last designated by the user by default, or may be used to frame a person, building or some other object on the preview aided image by default. The user may drag the target view frame 503 so that the target object to be photographed by the telephoto camera is located within the target view frame 503, thereby selecting the target object to be photographed by the telephoto camera. Moreover, the user can also change the target object to be photographed by the telephoto camera by dragging the target view frame 503, changing the position of the target view frame 503, and changing the content in the target view frame 503.

In other embodiments, the target view frame 503 is in a default position after entering the tele-assisted preview mode. The content in the target finder frame 503 may not be a target object that the user wants to photograph by the long focus camera, and the user has not specified the target object. After detecting the operation of dragging the target view frame 503 by the user, the mobile phone determines that the target object is specified by the user, and the content in the target view frame 503 is the target object specified by the user.

In the process of moving the target view frame 503, the live view frame 504 can also automatically move to avoid the target view frame 503, so as to avoid overlapping of the live view frame 504 and the target view frame 503, and facilitate the user to visually and clearly see the contents in the live view frame 504 and the target view frame 503.

For example, in the case shown in fig. 5C, after the user drags the target view frame 503, the tele-assistant preview interface displayed by the mobile phone may be as shown in fig. 5F.

In some embodiments, the size of the target viewfinder 503 is fixed. In other embodiments, the size of the target viewing frame 503 may vary. The zoom magnification of the image displayed within the live view frame 504 may be inversely related to the size of the target view frame 503. That is, the larger the target finder frame 503 is, the smaller the zoom magnification of the image within the live view frame 504 is; the smaller the target finder frame 503 is, the larger the zoom magnification of the image within the live view frame 504 is. The user can adjust the size of the target finder frame 503 to adjust the zoom magnification of the image in the live view frame 504.

Since the preview image captured by the tele camera in real time is displayed in the live view box 504, in some embodiments, the zoom ratio of the preview image captured by the tele camera in real time may also be inversely related to the size of the target view box 503.

Illustratively, referring to fig. 5G, a numeric flag 507 and a zoom flag 508 are displayed on the target finder frame 503. When the user holds the zoom mark 508 and drags the edge of the target frame 503, the size of the target frame 503 changes accordingly. The number in the number mark 507 corresponds to the size of the target finder frame 503 after the change. When the user directly drags the edge line of the target frame 503 without holding the zoom mark 508, the position of the target frame 503 is moved and the size of the target frame 503 is not changed.

As another example, a zoom mark 508 is displayed on the target frame 503, and when the user drags an edge of the target frame 503 for the first time after clicking the target frame, the size of the target frame 503 is changed accordingly. When the user clicks the edge of the target view frame 503 n (n is an integer greater than 1) times after the target view frame, or when the user directly drags the edge of the target view frame 503 without clicking the zoom mark 508, the position of the target view frame 503 is moved and the size of the target view frame 503 is not changed.

When the zoom magnification of the image in the live view frame 504 is changed, the size of the target view frame 503 is also changed. For example, when the user changes the number in the numeric symbol 507 shown in fig. 5G, or when the user performs a pinch operation or an operation opposite to the pinch operation in the live view frame 504, the zoom magnification of the image in the live view frame 504 changes, and the size of the target frame 503 changes accordingly.

The preview image captured by the tele camera in real time may be displayed in the live view box 504. In some embodiments, a prompt message may be displayed near the live view box 504, or the mobile phone may play a voice message to prompt the user that the image displayed in the live view box is the image captured by the telephoto camera.

In some embodiments, the size of the image displayed in the live view box 504 may correspond to a telephoto camera default zoom magnification (e.g., 5). In other embodiments, the zoom magnification of the image displayed within the live view frame 504 corresponds to the size of the target view frame 503. When the size of the target finder frame 503 is changed, the zoom magnification of the image displayed in the live view frame 504 is also changed accordingly. Illustratively, the zoom magnification of the image displayed within the live view box 504 in fig. 5E is increased to 4 as compared with fig. 5C, and the size of the preview image displayed within the live view box 504 is large, matching the zoom magnification of 4. In other embodiments, the size of the image displayed in the live view box 504 may correspond to the current zoom magnification of the auxiliary preview image.

In some embodiments, the size of the live view box 504 is fixed. In other embodiments, the user may also modify the size of the live view box 504.

In some embodiments, the size ratio of the live view frame 504 (i.e., the ratio of two adjacent sides of the live view frame 504) and the size ratio of the target view frame 503 (i.e., the ratio of two adjacent sides of the target view frame 503) may be matched with the image ratio of the telephoto-camera photosensor (i.e., the ratio of images formed by the photosensor in the width direction and the height direction), so that the viewing ranges of the live view frame 504 and the target view frame 503 may be maximized as much as possible.

On the tele-assistant preview interface, a user can intuitively browse and compare the preview image acquired by the assistant camera, the target object and the preview image acquired by the tele camera in real time through the assistant view frame 502, the target view frame 503 and the live view frame 504.

In some embodiments, the mobile phone may determine the current real-time motion gesture through a gyroscope, an acceleration sensor, or other sensors. The movement posture can include information such as the inclination angle and the position of the mobile phone. The mobile phone calculates a target motion posture corresponding to the mobile phone when the telephoto camera locks (or is called to shoot) the target object according to the target object specified in the target view frame 503, that is, when the target object is within the view range of the telephoto camera. Then, the mobile phone can calculate the adjustment information of the mobile phone, such as the offset distance, the offset direction, the deflection angle and the like from the current real-time motion attitude to the target motion attitude according to the current real-time motion attitude and the target motion attitude. The mobile phone can prompt the user according to the adjustment information to guide the user to move the mobile phone (including translation, turnover and the like) to the target motion posture, so that the target object is placed in the view finding range of the telephoto camera, and the telephoto camera can lock the target object, thereby shooting images.

For example, the current real-time motion posture is the motion posture shown in fig. 1C, and the target object is the object 1 to be photographed. For example, the object 1 to be photographed may be a target object in the target finder frame 503 in fig. 5C.

As shown in fig. 1C, the subject 1 to be photographed is not within the framing range of the telephoto camera. Corresponding to the tele-assisted preview interface shown in fig. 5C, the preview image captured in the live view box 504 does not include the target object.

If the object 1 is to be captured by the telephoto camera, the object 1 needs to be placed within the viewing range of the telephoto camera as shown in fig. 1D. In this way, the preview image collected by the telephoto camera can include the object 1 to be photographed. That is, the mobile phone needs to be in the target motion posture as shown in fig. 1D, so that the object 1 to be photographed is placed in the view range of the telephoto camera, and the telephoto camera can lock the object 1 to be photographed.

In some technical solutions, the mobile phone may determine, according to the content of the preview image currently acquired by the telephoto camera, a relative relationship between a position on the auxiliary preview image (the position may be referred to as a reference position) and a position of the target object on the auxiliary preview image, and a current real-time motion posture of the mobile phone, a target motion posture corresponding to the mobile phone when the target object moves to the reference position, that is, when the telephoto camera can capture the target object.

In other technical solutions, the mobile phone may determine a relative relationship between a first position of the content in the preview image acquired by the telephoto camera in the live view frame in the actual space and a second position of the target object in the target view frame in the actual space. And determining the target motion attitude corresponding to the mobile phone when the telephoto camera locks the target object at the second position according to the relative relationship and the current real-time motion attitude of the mobile phone.

In other technical solutions, because the viewing ranges of different cameras are different, the preview images acquired by different cameras can correspond to different area ranges of the display area. For example, as shown in fig. 6, the view range of the auxiliary camera may correspond to the entire auxiliary view frame 601. The field of view of the tele camera may correspond to the region 602. In this way, the content of the preview image captured by the telephoto camera displayed in the live view frame 504 is located in the region 602 at a position on the auxiliary preview image. When the target object in the target finder frame 603 is not within the finder range of the telephoto camera, the target object on the auxiliary preview image is outside the region 602. When the target object in the target finder frame 603 is within the finder range of the telephoto camera, the target object on the subsidiary preview image is within the area 602. The mobile phone may determine a target motion posture corresponding to the mobile phone when the target object is located in the area 602 according to the relative position of the target object on the current auxiliary preview image and the area 602 and the current real-time motion posture.

In some embodiments, the field of view of the tele camera may overlap with a central region of the field of view of the auxiliary camera. Thus, region 602 may be a central region of the display area. That is, the region 602 may be a central region of the auxiliary view frame 601.

Therefore, the mobile phone can determine the adjustment information according to the difference value between the current real-time motion posture and the target motion posture, and prompt the user to move the mobile phone according to the adjustment information. The method for prompting the user by the mobile phone according to the adjustment information can be various.

For example, in some embodiments, the handset may display a prompt identifier to direct the user to move the handset. For example, the prompt identification may direct the user in the direction of moving the handset. For example, the user is guided to move the mobile phone in the up, down, left, right, left up, or right down directions. Illustratively, referring to FIG. 7A, the prompt is identified as arrow 701. The direction indicated by the arrow 701 is the direction guiding the user to move the handset. The arrow 701 directs the user to move the handset to the left. For further example, referring to FIG. 7B, the prompt is identified as arrow 702, and the arrow 702 directs the user to move the phone to the lower left. For further example, referring to FIG. 7C, the prompt is identified as textual information 703. The text message 703 prompts the user to "please move the phone to the lower left".

It should be noted that the prompt information may give a user guidance in a general direction, so as to avoid a long-time search process caused by the user blindly searching for a target object all around, reduce the time for the telephoto camera to lock the target object, and improve the user experience.

It should be noted that in the actual shooting process, the user will usually flip the mobile phone naturally during the process of identifying the mobile phone according to the prompt. The user carries out subjective judgment according to the relative positions of the contents in the real-time view frame and the target view frame in the auxiliary view frame or according to the position of the target object in the actual three-dimensional space, so that the mobile phone is actively turned over in the process of moving the mobile phone, and the long-focus camera can lock the target object more quickly.

In other embodiments, the prompt identifier may also guide the user to move the mobile phone, so that the user knows the moving distance, and thus the user is guided more accurately, the user and the telephoto camera can lock the target object more quickly, and the time for the user to search for the target object is reduced.

For example, the prompt is identified as an arrow, the size of which indicates the distance the user is directed to move the handset. When the user moves the handset in the correct direction, the arrow becomes smaller (or shorter); when the user moves the handset in the wrong direction, the arrow becomes larger (or longer). For another example, the prompt identifier is text information, and the text information may be: please lean 30 ° down to the left, move 2cm ".

In other embodiments, the prompt identifier may also indicate whether the angle at which the user turns the mobile phone is correct, so as to give the user more precise guidance, so that the user and the telephoto camera can lock the target object more quickly. If the user moves the mobile phone in the correct direction and turns the mobile phone in the correct direction, the arrow becomes smaller (or shorter). If the direction of the user moving the mobile phone is correct, but the direction of the user turning the mobile phone is incorrect, the arrow is not reduced (or shortened). The arrow will be smaller (or shorter) after the user adjusts the flip direction of the handset.

In other embodiments, the handset may continuously guide the user through speech. For example, the cell phone may audibly instruct the user to "move up right," "move down," etc.

In other embodiments, the prompt identifier may prompt the user to adjust the motion posture of the mobile phone in a three-dimensional space, so as to give the user a more precise guidance, so that the user and the telephoto camera can lock the target object more quickly, and the time for the user to search for the target object is reduced. For example, the prompt content may include a moving direction and a flipping direction of the mobile phone. Illustratively, referring to fig. 7D, the prompt identification includes an arrow 704 and an arrow 705. The arrow 704 is used to prompt the user to move the handset to the left. The arrow 705 is used to prompt the user to flip the phone to the front of the touch screen (i.e., the side with the display function). As another example, the prompt is identified as a voice prompt message "please move the phone left and flip approximately 20 ° to the front of the touch screen".

If the user modifies the target object by dragging the target view-finding frame, the mobile phone can also determine adjustment information according to the modified target object, and prompt the user according to the adjustment information so as to guide the user to move the mobile phone.

And in the process that the user guides the mobile phone according to the prompt message, the target object is closer to the view finding range of the telephoto camera. The preview image acquired by the tele-camera displayed in the live view frame in real time is more and more similar to the image of the target object in the target view frame.

After the mobile phone moves, whether the target object is in the framing range of the telephoto camera or not can be determined, namely whether the telephoto camera locks the target object or not. For example, when the mobile phone determines that the current real-time motion gesture matches the target motion gesture, the target object is substantially within the view range of the telephoto camera, that is, the telephoto camera is determined to substantially lock the target object. For example, when the similarity between the current real-time motion posture and the target motion posture is determined to be greater than a preset value 4 (e.g., 90%), the mobile phone may determine that the current real-time motion posture matches the target motion posture.

After the mobile phone determines that the target object is locked by the telephoto camera, the display of the telephoto preview interface can be switched.

It should be noted that the method for determining the target object locked by the long-focus camera by the mobile phone may also be implemented in other various ways. For example, when the mobile phone determines that the image in the live view frame 504 matches the content of the image in the target view frame 503 through an image recognition technique, it determines that the telephoto camera substantially locks the target object, and switches to displaying the telephoto preview interface. For example, the cellular phone can calculate the similarity of the image in the live view frame 504 and the image in the target view frame 503. If the similarity is greater than or equal to the preset value 5 (for example, 80%), the mobile phone can determine that the long-focus camera basically locks the target object.

For example, the image matching algorithm based on image recognition may include a grayscale-based template matching algorithm, a feature-based matching algorithm, an optical flow method, and the like. For example, the grayscale-based template matching algorithm may include a sum of absolute differences (MAD), a Sum of Absolute Differences (SAD), a Mean Square Differences (MSD), a Sequential Similarity Detection (SSDA), and so on.

Generally, the similarity between images is determined by an image recognition technology, and complicated calculation such as convolution is required, so that the consumed calculation resources are large, and the calculation speed is low. Compared with image recognition, the method has the advantages that the similarity between the real-time motion attitude and the target motion attitude is calculated through data collected by a sensor such as a gyroscope and the like, the required calculation amount is small, and the calculation speed is high.

After the mobile phone is switched to the tele preview display interface, the preview image collected by the tele camera can be displayed on the tele preview interface in a full screen mode. And the auxiliary preview image and the target view frame are not displayed on the tele preview interface.

The size ratio of the image on the tele preview interface and the size ratio of the image in the live view frame may or may not be the same. The target view frame and the live view frame are not displayed on the tele preview interface.

In one case, after switching to the scene preview interface, the zoom magnification of the preview image on the tele preview interface is the default zoom magnification. The user can modify the size of the default zoom magnification at the setting interface. In another case, after the zoom is switched to the tele preview interface, the zoom magnification of the preview image on the tele preview interface is the same as the zoom magnification corresponding to the size of the target finder frame before the zoom is switched.

In some embodiments, the tele preview interface includes a shoot control. For example, referring to fig. 8A, after the mobile phone detects that the user clicks the shooting control 801 on the tele preview interface, an image is shot.

In other embodiments, the tele preview interface can be as shown in fig. 8B or fig. 8C, and after the mobile phone switches to the tele preview interface for display, one or more images are automatically captured, so that the operation of the user for instructing capture can be saved.

After the zoom-in preview interface is switched to display, the target object may be deviated from the center of the screen or may not appear on the zoom-in preview interface (i.e., the target object is lost), so that the zoom-in camera cannot lock the target object. Illustratively, the tele preview interface may be as shown in FIG. 9A or FIG. 9B.

Thus, in other embodiments, the cell phone may continue to determine the current real-time motion pose after switching to displaying the tele-preview interface. If the current real-time motion posture is not matched with the target motion posture; or, if the preview image acquired by the tele-camera in real time does not match the image in the target view-finding frame, the user is continuously prompted to move the mobile phone by adopting the manner described in the above embodiment, so that the tele-camera can lock the target object again. For example, the prompt identifier for prompting the user to move the mobile phone may be an arrow 901 in fig. 9A or an arrow 902 in fig. 9B.

After switching to the display tele preview interface, if the current real-time motion posture is matched with the target motion posture; or, if the preview image acquired by the tele-camera in real time is matched with the image in the target view frame. Or, if the user moves the mobile phone according to the guidance of the mobile phone, the current real-time motion posture is matched with the target motion posture; or enabling the preview image acquired by the long-focus camera in real time to be matched with the image in the target view frame. Then, in one solution, the mobile phone automatically takes the image. In another technical scheme, the mobile phone can stop prompting the user, and shoot the image after detecting the operation of shooting instructed by the user. In another technical scheme, the mobile phone can prompt a user that a target object is locked through modes of displaying information, voice, vibration and the like, and an image is shot after the user indicates shooting operation is detected.

The automatic shooting is automatically performed when the current real-time motion posture is matched with the target motion posture or when the image in the live view frame 504 is matched with the image in the target view frame 503, so that the shot object is a target object specified by the user, the operation of the user can be saved, and the shooting efficiency and the user experience are improved.

After the mobile phone captures the image, if the target object is deviated (that is, the target object is not located in the center of the captured image) or lost (that is, the target object is not captured, and the target object does not appear on the captured image), so that the tele-camera does not lock the target object any longer, the mobile phone may further continue to guide the user by using the method described in the above embodiment, so that the tele-camera may lock the target object again. Particularly, after the mobile phone automatically shoots the image, the automatically shot image may not be ideal, and the user may continue to move the mobile phone according to the guidance of the mobile phone, so as to manually shoot one or more images with better effect after the target object is re-locked.

In some embodiments, after switching to displaying the tele preview interface, if the user wants to change the target object, the phone may exit the tele assist mode first. Illustratively, the handset may exit the tele-assist mode upon detecting that the user has clicked "x" in fig. 8B. After the mobile phone enters the tele-assist mode again, the user re-designates a new target object through the target finder frame.

In other embodiments, after switching to the tele preview display interface, if the user wants to change the target object, the mobile phone may exit the tele preview interface, and return to the tele auxiliary preview interface including the target view frame, so as to reselect and designate a new target object through the target view frame. For example, in the case that the mobile phone displays the tele preview interface, after detecting that the user clicks a back key, the mobile phone may return to display the tele auxiliary preview interface including the target view frame.

In some other scenarios, the target object is moving. For example, the target object is continuously moving. For another example, after the tele-assisted preview interface is displayed, the target object suddenly starts moving. For another example, after switching to displaying the tele preview interface, the target object suddenly starts moving.

In the case where the target object is in a moving state, the user and the telephoto camera more easily lose the target object. In some embodiments, the mobile phone may track the target object in motion state in real time. The target view box on the tele-assisted preview interface can move in real time as the target object moves. And the mobile phone can calculate the real-time target motion attitude corresponding to the target object in the motion state. The mobile phone calculates real-time adjustment information according to the difference between the current real-time motion attitude and the real-time target motion attitude, so that prompt information for a user is adjusted in real time according to the real-time adjustment information, and the user is guided to move the mobile phone.

Similar to the process described in the above embodiment, in the case where the mobile phone displays the tele preview interface, when the current real-time motion posture matches the real-time target motion posture, or when the image in the real-time view frame 504 matches the content of the image in the target view frame 503, the mobile phone determines that the tele camera substantially locks the target object, thereby switching to displaying the tele preview interface.

Similar to the process described in the above embodiment, after switching to displaying the tele preview interface, the mobile phone may automatically capture an image.

Or, similar to the process described in the foregoing embodiment, after switching to displaying the tele preview interface, the mobile phone may continue to acquire the auxiliary preview image in the background and track the target object in real time. If the current real-time motion posture is matched with the real-time target motion posture or if the preview image currently acquired by the long-focus camera is matched with the image of the target object tracked in real time, the mobile phone can be triggered to automatically shoot the image. Thus, the user can be assisted in photographing a dynamic target object using the telephoto lens.

It should be noted that, when the target object is in a moving state, the mobile phone automatically shoots an image, and can shoot the target object in time, so as to prevent the user from having to click the shooting control and prevent the shooting target object from running out of the view finding range of the telephoto camera.

And under the condition that the target object is in a motion state, the mobile phone can also display a motion mark on the tele auxiliary preview interface. For example, the motion flag may be used to indicate a motion direction of the target object, an outline of the target object, and the like. The motion mark can facilitate a user to intuitively know the information such as the size, the position, the motion direction and the like of the target object. Illustratively, FIG. 10A shows a schematic representation of a motion marker 1001. The elliptical dotted line in the motion marker 1001 is used to mark the outline and size of the moving target object. The arrow in the motion marker 1001 is used to mark the direction of motion of the target object. As yet another example, FIG. 10B shows a schematic view of a motion marker 1002. The "[ ]" in the motion labeling 1002 is used to label the outline and size of the moving target object. The arrow in the motion flag 1002 is used to flag the direction of motion of the target object.

The above description mainly takes the example that the mobile phone guides the user to take a picture by using the telephoto camera. During the recording process, the user may also specify the target object. The mobile phone can also prompt the user by adopting the method described in the above embodiment to guide the user to move the mobile phone when the user adopts the tele-camera to record the video, so as to help the user to lock the target object as much as possible by using the tele-camera, and further track and record the video of the target object.

For example, referring to fig. 11A, upon entering the tele-assist mode, a first control 1101 and a second control 1102 may be included on the tele-assist preview interface. After detecting that the user clicks the first control 1101, the mobile phone enters the tele auxiliary photographing sub-mode, and the mobile phone can guide the user to move, so that the tele camera locks the target object and takes a picture.

After the mobile phone detects the operation of the user clicking the second control 1102, as shown in fig. 11B, the mobile phone may enter the tele-assisted recording sub-mode. Under the auxiliary long-focus video recording sub-mode, the mobile phone can guide the user to move so that the long-focus camera locks the target object as much as possible.

After detecting the operation of clicking the video recording control 1103 by the user, the mobile phone starts to record video. In the process of recording, especially in the process of recording the target object in the motion state, referring to fig. 11C, the mobile phone may guide the user to move the mobile phone, so that the user can lock the target object as much as possible by using the telephoto camera, thereby achieving the purpose of tracking the target object in real time and recording the target object.

In addition, the method for capturing the image by guiding the electronic equipment to move and assisting the telephoto camera of the electronic equipment to lock the target object can be applied to other various scenes. For example, in a multi-camera monitoring apparatus, a plurality of cameras for monitoring include a wide-angle camera and a telephoto camera. The monitoring area of the wide-angle camera is wide, and through an image recognition technology, a monitoring device can capture a suspicious or important monitored area, namely the suspicious or important monitored area is equivalent to the target object. The monitoring device can guide the tele camera to move, so that the picture of a suspicious or important monitoring area is locked and shot.

Another embodiment of the present application provides a photographing method, referring to fig. 12, the method may include:

1201. the electronic device starts the camera.

1202. The electronic equipment adopts a first camera and a second camera to respectively collect a first preview image and a second preview image, the second camera is a long-focus camera, and the viewing range of the first camera is larger than that of the second camera.

1203. The electronic equipment displays a first preview interface, wherein the first preview interface comprises a first view frame, a second view frame and a third view frame; the first viewing frame is used for displaying a first preview image; the image in the second viewing frame is a part of the first preview image; the content in the second viewing frame is a target object to be shot by the second camera; the third viewing frame is used for displaying the second preview image.

1204. The electronic equipment displays first prompt information, and the first prompt information is used for guiding a user to move the electronic equipment, so that the target object can be locked by the second camera after the electronic equipment moves.

Therefore, after the electronic equipment is switched from the first camera such as the wide-angle camera or the middle-focus camera to the second camera such as the long-focus camera, the electronic equipment can guide the user to move the electronic equipment through the prompt information.
