Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a display control method and electronic equipment.

Background

Currently, in a scene where an electronic device such as a mobile phone and a tablet computer takes an image, the electronic device can only acquire an image of a certain viewing angle through one camera at the same time, and displays a preview image acquired by the corresponding camera. For example, the electronic device may only display the image captured by the front camera or the image captured by the rear camera on the screen at the same time.

Specifically, under the condition that the electronic device acquires an image through one of the front camera and the rear camera, if a user needs to view images with different viewing angles in a shooting scene in the electronic device, the user may be required to control the electronic device to open the other camera, or the user is required to manually move the electronic device, so that the electronic device acquires and displays the image with the corresponding viewing angle on a screen. Therefore, the steps of displaying preview images with different viewing angles by the electronic device are complicated.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that "/" in this context means "or", 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. "plurality" means two or more than two.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

The terms "first" and "second," and the like, in the description and in the claims of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first input and the second input, etc. are for distinguishing different inputs, rather than for describing a particular order of inputs.

According to the display control method and the electronic device provided by the embodiment of the invention, under the condition that the preview picture displayed on the screen is the first preview picture, the preview picture displayed on the screen can be updated to the second preview picture from the first preview picture through the first input of a user; the first preview picture comprises at least two first preview images with different view angles, or a panoramic preview image synthesized by the at least two first preview images with different view angles. In this way, in a scene in which a user needs to view multiple preview images at different view angles, the electronic device may simultaneously display multiple preview images at different view angles, or directly display a panoramic preview image synthesized by multiple preview images at different view angles, instead of displaying only one preview image at the same time. Therefore, the electronic equipment is prevented from frequently switching the preview images of the single view angle displayed on the screen so as to show the preview images of different view angles to the user. Namely, the steps of displaying the preview images of different view angles by the electronic equipment are simplified, and the preview images of different view angles displayed by the electronic equipment are convenient for a user to view.

The electronic device in the embodiment of the invention can be a mobile electronic device or a non-mobile electronic device. The mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile electronic device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.

It should be noted that, in the display control method provided in the embodiment of the present invention, the execution main body may be an electronic device, or a Central Processing Unit (CPU) of the electronic device, or a control module in the electronic device for executing the display control method. In the embodiment of the present invention, an electronic device executes a display control method as an example, and the display control method provided in the embodiment of the present invention is described.

The electronic device in the embodiment of the present invention may be an electronic device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.

The following describes a software environment to which the display control method provided by the embodiment of the present invention is applied, by taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application. For example, applications such as a system setup application, a system chat application, and a system camera application. And the third-party setting application, the third-party camera application, the third-party chatting application and other application programs.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the display control method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the display control method may operate based on the android operating system shown in fig. 1. That is, the processor or the electronic device may implement the display control method provided by the embodiment of the present invention by running the software program in the android operating system.

The following describes the display control method provided in the embodiment of the present invention in detail with reference to the flowchart of the display control method shown in fig. 2. Wherein, although the logical order of the display control methods provided by embodiments of the present invention is shown in method flow diagrams, in some cases, the steps shown or described may be performed in an order different than here. For example, the display control method shown in fig. 2 may include steps 201 and 202:

step 201, the electronic device acquires at least two first preview images with different view angles.

In the embodiment of the invention, in a scene of photographing, video recording or video call, the electronic device may collect an image and display a preview image (for example, a first preview image described below) on the screen.

Specifically, the view angles of different first preview images in at least two first preview images with different view angles are different.

Optionally, the electronic device provided in the embodiment of the present invention may include at least two cameras, and the viewing angles (or referred to as viewing orientations or viewing angles) of the different cameras are different.

It will be appreciated that the viewing angle of a camera may be described as the viewing angle of an image captured by the camera.

Optionally, the preview images at different view angles are images acquired by different cameras in the electronic device.

For example, the different first preview image of the at least two first preview images with different view angles may be an image captured by different cameras in the electronic device.

It can be understood that, because the electronic device is provided with the cameras with different view angles, the electronic device can acquire images with different view angles, such as the above-mentioned at least two first preview images with different view angles.

In addition, in the embodiment of the present invention, it is assumed that the electronic device is fixed, and the position of each camera in the electronic device is fixed, so that the view angle of each camera in the electronic device is not changed.

It should be emphasized that in the embodiment of the present invention, the view angles of all the cameras in the electronic device may cover an angular range of 360 degrees of the position where the electronic device is located. Therefore, even if the electronic equipment is fixed, namely the user does not move the position of the electronic equipment, the electronic equipment can acquire an image of any view angle through the camera therein.

It can be understood that in the embodiment of the present invention, the viewing angles of different cameras in the electronic device may be overlapped or adjacent to each other, so that the viewing angles of all the cameras in the electronic device cover an angular range of 360 degrees of the position where the electronic device is located.

Optionally, in the embodiment of the present invention, the camera in the electronic device may be a pop-up camera, a slide-cover camera, a built-in fixed camera, or the like. Specifically, the combination form of at least two cameras in the electronic device is not particularly limited in the embodiments of the present invention, and may be any realizable form. For example, the at least two cameras in the electronic device may include a partial pop-up camera and a partial built-in fixed camera, where the at least two cameras are both pop-up cameras, or the at least two cameras are both built-in fixed cameras.

Illustratively, the electronic device provided by the embodiment of the invention includes six cameras, and the six cameras are respectively disposed on six surfaces of the electronic device, that is, the six cameras are respectively disposed on six surfaces of a front surface, a rear surface, a left surface, a right surface, an upper surface and a lower surface of the electronic device. The camera arranged on the front surface of the electronic equipment can be a front-facing camera, and the camera arranged on the rear surface of the electronic equipment can be a rear-facing camera.

It can be understood that, since the user generally holds the middle-lower position of the longer side of the electronic apparatus when using the electronic apparatus, the cameras can be disposed at the upper ends of the left and right surfaces of the electronic apparatus.

For example, as shown in fig. 3, this embodiment provides a schematic diagram of camera distribution in an electronic device. In fig. 3, (a) to (c) show a perspective view, a front view, and a left side view of the electronic apparatus, respectively. The electronic equipment comprises six cameras, namely a front camera K1, a rear camera K2, a left camera K3, a right camera K4, an upper camera K5 and a lower camera K6. The front camera K1 is located on the front surface of the electronic device (i.e., the surface ADHE), and the viewing angle is in front of the electronic device (i.e., within a certain angle range of the front); the rear camera K2 is positioned on the rear surface (surface BCGF) of the electronic equipment, and the viewing angle is the rear of the electronic equipment; the left camera K3 is located on the left surface of the electronic device (i.e. surface ABFE), and the viewing angle is the left of the electronic device; the right camera K4 is located on the right surface of the electronic device (i.e. surface DCGH), and the viewing angle is the right of the electronic device; the upper camera K5 is positioned on the upper surface (surface ABCD) of the electronic equipment, and the view angle is above the electronic equipment; the lower camera K6 is located on the lower surface of the electronic device (i.e., surface EFGH), and the viewing angle is below the electronic device.

Specifically, (b) in fig. 3 shows the range of the view angle of the left camera K3, the right camera K4, the upper camera K5, and the lower camera K6, and (c) in fig. 3 shows the range of the view angle of the front camera K1 and the rear camera K2.

The direction mentioned in the embodiment of the present invention may be a direction based on a screen of the electronic device. Specifically, the positive direction of the y-axis shown in fig. 3 is the front of the screen of the electronic device, the negative direction of the y-axis is the rear of the screen of the electronic device, the positive direction of the x-axis is the right of the screen of the electronic device, the negative direction of the x-axis is the left of the screen of the electronic device, the positive direction of the z-axis is the upper of the screen of the electronic device, and the negative direction of the z-axis is the lower of the screen of the electronic device.

Step 202, the electronic device displays a first preview picture on a screen according to at least two first preview images with different view angles.

The first preview image includes at least two first preview images with different view angles (that is, the first preview image includes at least two first preview images themselves), or a panoramic preview image synthesized by at least two first preview images with different view angles.

It is understood that the number of the at least two first preview images with different view angles is smaller than or equal to the number of cameras in the electronic device, for example, the number of the at least two first preview images with different view angles is smaller than or equal to 6.

Optionally, in this embodiment of the present invention, the electronic device may provide multiple viewing modes, such as a multi-view viewing mode, an adjustable single-view viewing mode, and a three-dimensional (3D) panoramic viewing mode. The multi-view mode refers to the electronic device displaying a preview image of each of a plurality of view angles in a preview screen at the same time. The adjustable single-view viewing mode refers to the mode that the electronic equipment displays a preview image of a certain viewing angle in a preview picture at the same moment, and supports the electronic equipment to switch the viewing mode into a multi-view viewing mode or a three-dimensional panoramic viewing mode. The three-dimensional panoramic view mode is a mode in which the electronic device displays a panoramic preview image in which images of a plurality of view angles are combined on a preview screen at the same time.

Specifically, the multi-view mode, the adjustable single-view mode, and the three-dimensional panoramic view mode may be collectively referred to as a 3D view mode.

In addition, the above-described adjustable single-view mode is different from the conventional single-view mode. The conventional single-view viewing mode refers to the mode that the electronic equipment displays a preview image of a certain viewing angle in a preview picture at the same moment, and does not support the electronic equipment to switch the viewing mode into a multi-view viewing mode or a three-dimensional panoramic viewing mode.

It is understood that in the application scenario 1, the electronic device may display a first preview screen in the multi-view mode, that is, display at least two first preview images with different view angles on the screen. In the application scene 2, the electronic device may display a first preview screen in the three-dimensional panoramic view angle viewing mode, that is, a panoramic preview image synthesized by at least two first preview images with different viewing angles is displayed on the screen.

Optionally, the electronic device may provide a control/function for entering a viewing mode of a multi-view viewing mode, a tunable single-view viewing mode, or a three-dimensional (3D) panoramic viewing mode to trigger the electronic device to be in the viewing mode of the multi-view viewing mode, the tunable single-view viewing mode, or the three-dimensional panoramic viewing mode.

For example, the electronic device may provide two functions of "3D photographing" and "3D video recording" in a camera application, so as to trigger the electronic device to capture an image through a camera and display a corresponding preview image on a screen in a view finding mode of a multi-view finding mode, an adjustable single-view finding mode, or a three-dimensional panoramic view finding mode.

Correspondingly, the electronic equipment can provide two functions of 'photographing' and 'recording' in the camera application so as to trigger the electronic equipment to acquire images through the camera and display corresponding preview images on the screen in a conventional single-view-angle view finding mode.

Optionally, when the electronic device starts to execute a function corresponding to "3D photographing" or "3D video recording", the electronic device may acquire an image through the camera in the predefined viewing mode and display a corresponding preview image on the screen.

The predefined viewing mode may be any one of the above-mentioned multi-view viewing mode, adjustable single-view viewing mode, and three-dimensional panoramic viewing mode.

Illustratively, in the application scenario 1 of the embodiment of the present invention, the first preview screen may include at least two first preview images having different viewing angles. In the application scenario 2 according to the embodiment of the present invention, the first preview screen is a panoramic preview image synthesized from first preview images with at least two different view angles.

It should be noted that, in the application scenario 1, the electronic device may display different first preview images of at least two first preview images with different view angles in different areas of the screen.

Illustratively, as shown in fig. 4, the electronic device includes a "3D video recording" control 41, a "3D photo taking" control 42, a "photo taking" control 43, a "video recording" control 44, a "photo taking" control 45, and a region P1-a region P6 in a photo preview interface displayed on the screen. The "3D video recording" control 41 and the "3D photo taking" control 42 are used to instruct the electronic device to display corresponding preview images on the screen in the viewing angle view mode, the adjustable single viewing angle view mode or the three-dimensional panoramic view mode. The "take picture" control 43 and the "record" control 44 are used to trigger the electronic device to display only a viewfinder image for a certain viewing angle on the screen. The first preview image M1 to the first preview image M6 are displayed in the region P1 to the region P6 in this order with the viewing angle being front, rear, left, right, upper, and lower. Specifically, the "3D video recording" control 41 is in the selected state. The electronic device displays the "3D video" in fig. 4 by bolding, and identifies that the "3D video" control 41 is in the selected state.

Optionally, in the embodiment of the present invention, if the electronic device detects that at least two cameras are included in the electronic device, the electronic device may provide a "3D photographing" function and a "3D video recording" function, for example, a "3D video recording" control 41 and a "3D photographing" control 42 are displayed on the screen. On the contrary, if the electronic device does not detect that at least two cameras are included therein, the electronic device does not provide the functions of "3D photographing" and "3D video recording", for example, the "3D video recording" control 41 and the "3D photographing" control 42 are not displayed on the screen, but the "photographing" control 43 and the "video recording" control 44 are displayed, that is, only the normal viewing mode is supported.

In addition, when the electronic device starts to take or record a picture, for example, when a camera application of the electronic device is turned on, the electronic device defaults to a "taking picture" function, that is, an image is acquired through a camera in a conventional single-view mode and a corresponding preview image is displayed.

It should be noted that, the electronic device may synthesize, by using an image panorama stitching technique, at least two first preview images with different view angles into a panoramic preview image (i.e., a panoramic image). Wherein. The image panorama stitching technology is a technology for stitching a plurality of images (a certain overlapping part exists between every two of the plurality of images, and the images can be obtained at different time, at different visual angles or by different sensors (such as different cameras)) into a seamless panoramic image or a high-resolution image. Specifically, the image panorama stitching technology may perform feature point matching on two images having a certain overlapping portion through an algorithm (for example, Scale-invariant feature transform (SIFT)) to obtain corresponding points, and then obtain a stitching result of the two images by overlapping the obtained corresponding points and retaining the non-overlapping portion of the two images.

It should be noted that, in the application scene 2, the electronic device may combine at least two first preview images with different view angles into one panoramic preview image.

It is to be understood that the viewing angle of the panoramic preview image composed of the at least two first preview images having different viewing angles may be the viewing angle of the panoramic preview image displayed on the screen, and may be the viewing angle of any one of the at least two first preview images having different viewing angles.

For example, the number of images of at least two first preview images having different view angles may be 4. For example, the viewing angles of the at least two first preview images having different viewing angles may include four viewing angles of front, rear, left, and right, and the viewing angle of the corresponding first preview screen may be any one of front, rear, left, and right. Alternatively, the view angles of the at least two first preview images having different view angles may include four view angles of upper, lower, left, and right, and accordingly, the view angle of the first preview screen may be any one of upper, lower, left, and right.

Illustratively, in conjunction with fig. 4, as shown in fig. 5, the electronic device includes a "3D video recording" control 41, a "3D photo taking" control 42, a "photo taking" control 43, a "video recording" control 44, and a "photo taking" control 45, and a panoramic preview image 51 in a shooting preview interface displayed on the screen. The panoramic preview image 51 is a first preview screen, the panoramic preview image 51 is synthesized by four first preview images with four viewing angles of front, rear, left and right, and the viewing angle of the panoramic preview image 51 is the front (i.e., one of the front, rear, left and right viewing angles).

It can be understood that the first preview image displayed on the screen by the electronic device is obtained according to at least two first preview images with different view angles, that is, the first preview image includes at least two first preview images with different view angles or a panoramic preview image synthesized by at least two first preview images with different view angles, so that the electronic device can display preview images with different view angles to a user at the same time, and the user can conveniently view the preview images with different view angles.

It should be noted that, in the display control method provided in the embodiment of the present invention, when the preview image displayed on the screen is the first preview image, the preview image displayed on the screen may be updated from the first preview image to the second preview image through the first input of the user; the first preview picture comprises at least two first preview images with different view angles, or a panoramic preview image synthesized by the at least two first preview images with different view angles. In this way, in a scene in which a user needs to view multiple preview images at different view angles, the electronic device may simultaneously display multiple preview images at different view angles, or directly display a panoramic preview image synthesized by multiple preview images at different view angles, instead of displaying only one preview image at the same time. Therefore, the electronic equipment is prevented from frequently switching the preview images of the single view angle displayed on the screen so as to show the preview images of different view angles to the user. Namely, the steps of displaying the preview images of different view angles by the electronic equipment are simplified, and the preview images of different view angles displayed by the electronic equipment are convenient for a user to view.

Optionally, after step 202, the display control method provided in the embodiment of the present invention may further include step 203 and step 204:

step 203, the electronic device receives a first input of a user.

The first input is used for triggering the electronic device to update the preview picture displayed on the screen, such as being used for triggering the electronic device to change the view mode and update the preview picture displayed on the screen.

It should be noted that the screen of the electronic device provided in the embodiment of the present invention may be a touch screen, and the touch screen may be configured to receive an input from a user and display a content corresponding to the input to the user in response to the input. The first input may be a touch screen input, a fingerprint input, a gravity input, a key input, or the like. Specifically, the embodiment of the present invention does not specifically limit the manner of the first input, and may be any realizable manner.

For example, the first input may be an input of the first preview screen by a user, or an input of a control provided by the electronic device for triggering an update of the preview screen.

Step 204, the electronic device responds to the first input, and updates the preview picture displayed on the screen from the first preview picture to the second preview picture.

The second preview picture is obtained according to the at least one second preview image, and the view angles of different second preview images in the at least one second preview image are different.

Alternatively, the second preview screen may include a plurality of preview images, or a panoramic preview image in which a plurality of preview images are combined.

Optionally, the view angle of the preview image forming the second preview screen is the same as or different from the view angle of the first preview image with at least two different view angles.

For example, in the application scenario 1, the electronic device may display a second preview screen on the screen in a multi-view mode, an adjustable single-view mode, or a three-dimensional panoramic view mode. Likewise, in the application scene 2, the electronic apparatus may display the second preview screen on the screen in the multi-view mode, the adjustable single-view mode, or the three-dimensional panoramic view mode.

In example 1 of the embodiment of the present invention, the electronic device may display a second preview screen in the multi-view mode; in example 2, the electronic device may display a second preview screen in an adjustable single-view mode; in example 3, the electronic device may display a second preview screen in the three-dimensional panoramic viewing mode.

That is, the electronic apparatus may update the view mode in which the preview screen is displayed in real time in a case where the preview screen is displayed on the screen, so that the electronic apparatus displays preview images of different view angles on the screen.

It should be noted that, with the display control method provided in the embodiment of the present invention, when the view angle of the preview interface that the user needs to view changes, the electronic device may update the preview screen in real time, for example, update the view angle of the preview image included in the preview screen. Thus, the diversity and flexibility of displaying preview images by the electronic device can be further improved.

Optionally, in the embodiment of the present invention, when the electronic device updates the preview image, and when the electronic device cancels displaying the preview image at a certain view angle, the camera at the view angle may be closed, that is, the image acquisition by the camera is stopped; on the contrary, when the electronic device starts to display a preview image of a certain view angle, the camera of the view angle can be turned on, that is, the image acquisition through the camera is started. Therefore, under the condition that a user does not need to look up preview images of certain viewing angles, the electronic equipment can close the cameras of the viewing angles, the loss of the cameras in the electronic equipment is reduced, and the electric energy of the electronic equipment is saved.

Optionally, the at least one second preview image is different from the at least two first preview images with different view angles, or the at least one second preview image is the same as the at least two first preview images with different view angles.

It is understood that, when at least one second preview image is different from at least two first preview images having different view angles, it is described that the view angle of the preview image in the first preview screen is changed from that in the second preview screen. On the contrary, when at least one second preview image is identical to the first preview images having at least two different view angles, it is described that the view angle of the preview image in the first preview image is not changed from that in the second preview image.

Optionally, the user may trigger the electronic device to update the preview screen to the second preview screen by inputting the first preview screen displayed on the screen. For example, the first input may be an input of a preview screen displayed on the screen by the user.

Alternatively, in the case of application scenario 1 in combination with example 2, the first input may be a double-click input by the user to a preview image of a certain viewing angle of the plurality of preview images of different viewing angles displayed on the screen. Namely, the electronic equipment is triggered to switch the view mode from the multi-view mode to the adjustable single-view mode.

Specifically, when the electronic device displays a preview screen including a plurality of preview images with different view angles in the multi-view mode, the user performs a double-click input (i.e., a first input) on a preview image with a certain view angle in the plurality of preview images, and may trigger the electronic device to display the preview image with the view angle in the adjustable single-view mode.

Illustratively, in conjunction with fig. 4, after the user makes a double-click input on the first preview image M1 displayed in the region P1 in fig. 4 with the viewing angle at the front, the electronic device may display the first preview image M1 in the region P7 on the screen in the adjustable single-view mode, as shown in fig. 6. It is apparent that the display size of the first preview image M1 in the region P1 shown in fig. 4 is smaller than the display size in the region P7 shown in fig. 6.

In the case of application scenario 1 in conjunction with example 3, the first input may be a user input to a multi-finger pinch (e.g., a three-finger pinch) on the screen (i.e., a multi-finger inward swipe input), i.e., an input where the user touches the screen with multiple fingers and swipes the multiple fingers toward the center of the screen, or an input where the user swipes the multiple fingers toward the middle of the screen. Namely, the electronic equipment is triggered to switch the view mode from the multi-view mode to the three-dimensional panoramic view mode.

Specifically, when the electronic device displays a preview screen including multiple preview images with different view angles in the multi-view mode, a user performs a multi-finger pinch input (i.e., a first input) on the screen, which may trigger the electronic device to display a panoramic preview image synthesized from the multiple preview images in the three-dimensional panoramic view mode.

Illustratively, in conjunction with fig. 4 and 5, after a user makes a multi-finger pinch input on the screen shown in fig. 4, the electronic device may display the contents as shown in fig. 5.

In the case of application scenario 2 in conjunction with example 1, the first input may be an input of a plurality of fingers of the user sliding outward on the screen, i.e., triggering the electronic device to switch the view mode from the three-dimensional panoramic view mode to the multi-view mode.

Specifically, when the electronic device displays a panoramic preview image synthesized from a plurality of preview images at different viewing angles in the three-dimensional panoramic viewing mode, a plurality of fingers of a user slide outward on the screen to input, which may trigger the electronic device to display the plurality of preview images in the multi-view viewing mode.

Illustratively, in conjunction with fig. 4 and 5, after a user makes an input of a slide-out on the screen shown in fig. 5, the electronic device may display the contents as shown in fig. 4.

In the case of application scenario 2 in conjunction with example 2, the first input may be an input of a plurality of fingers of the user sliding inward on the screen, i.e., triggering the electronic device to switch the viewing mode from the three-dimensional panoramic viewing mode to the adjustable single-view viewing mode.

Specifically, when the electronic device displays a panoramic preview image synthesized from a plurality of preview images at different view angles in the three-dimensional panoramic view mode, an input that a plurality of fingers of a user slide inward on the screen may trigger the electronic device to respectively display a preview image at one of the view angles in the adjustable single-view-angle view mode. At this time, the electronic device displays a preview image of a default viewing angle in the adjustable single-view viewing mode, such as a preview image of a viewing angle corresponding to the current viewing angle of the panoramic preview image.

Illustratively, in conjunction with fig. 5 and 6, after the user makes an input of sliding inward on the screen shown in fig. 5, the electronic device may display the contents as shown in fig. 6.

Optionally, in the display control method provided in the embodiment of the present invention, when the electronic device is in the adjustable single-view mode, the electronic device may switch the view mode to the multi-view mode or the three-dimensional panoramic view mode. Specifically, in the case that a preview image of one view angle is included in a preview image displayed on the screen of the electronic device, the electronic device may update the preview image to include multiple preview images of different view angles or update the preview image to be a panoramic preview image synthesized according to the multiple preview images of different view angles under the trigger input of the user.

Optionally, when the electronic device is in the adjustable single-view viewing mode, an input that a plurality of fingers of the user slide outward on the screen may trigger the electronic device to switch the viewing mode from the adjustable single-view viewing mode to the multi-view viewing mode.

Specifically, when the electronic device displays a preview image according to a certain viewing angle in the adjustable single-view viewing mode, an input of sliding a plurality of fingers of the user outward on the screen may trigger the electronic device to display a plurality of preview images of different viewing angles in the adjustable single-view viewing mode, such as a plurality of preview images of all viewing angles or a plurality of preview images that have been recently displayed in the multi-view viewing mode.

Illustratively, in conjunction with fig. 4 and 6, after the user makes an input of sliding outward on the screen shown in fig. 6, the electronic device may display the contents as shown in fig. 4.

Optionally, when the electronic device is in the adjustable single-view viewing mode, an input that a plurality of fingers of the user slide inward on the screen may trigger the electronic device to switch the viewing mode from the adjustable single-view viewing mode to the three-dimensional panoramic viewing mode.

Specifically, when the electronic device displays a preview image according to a certain viewing angle in the adjustable single-view viewing mode, an input of sliding a plurality of fingers of the user inward on the screen may trigger the electronic device to display a panoramic preview image synthesized by a plurality of preview images at different viewing angles in the three-dimensional panoramic viewing mode, such as a panoramic preview image synthesized by a plurality of preview images at all viewing angles or a panoramic preview image recently displayed in the three-dimensional panoramic viewing mode.

Illustratively, in conjunction with fig. 5 and 6, after the user makes an input of sliding outward on the screen shown in fig. 6, the electronic device may display the contents as shown in fig. 5.

In the embodiment of the invention, the electronic device can update the first preview picture into the second preview picture through the first input in the multi-view viewing mode, and specifically can cancel the display of the preview image of some viewing angles and increase the display of the preview image of some viewing angles.

Alternatively, in the case of application scene 1 in conjunction with example 1, the first input may be an input by the user to slide down a preview image of a certain viewing angle included in the first preview screen.

Illustratively, in conjunction with fig. 4, after the user makes a downward slide input (i.e., a first input) to the first preview image M2 in the region P2 shown in (a) of fig. 7, the electronic apparatus may display the contents as shown in (b) of fig. 7 and close the rear camera K2 corresponding to the first preview image M2. Note that the region P8 shown in fig. 7 (b) includes the first preview image M1, and the first preview images M3 to M6 are displayed in the regions P3 to P6 in this order with the viewing angles being left, right, upper, and lower.

Optionally, the electronic device may provide a control (denoted as an on-off control) for controlling each camera to be turned on or off, that is, a control for controlling whether the electronic device displays a preview image for each viewing angle.

Alternatively, in the case where the electronic device displays a preview screen (e.g., the first preview screen) on the screen, a specific input (e.g., a long press input) on the screen by the user may trigger the electronic device to display various switch controls on the screen.

In addition, in the case where the electronic device displays the respective switch controls on the screen, another specific input (such as a long press input) by the user on the screen may trigger the electronic device to cancel displaying the respective switch controls on the screen.

Illustratively, in conjunction with FIG. 4, after the user makes a long press input on the screen shown in FIG. 4, the electronic device may display the switch controls S1-S6 as shown in FIG. 8. The switch controls S1 to S6 are respectively used for controlling the electronic device to control the cameras K1 to K6 to be turned on or off, that is, for controlling the electronic device to control whether to display the preview image of the corresponding viewing angle on the screen. Accordingly, the electronic apparatus in fig. 8 can display the first preview image M1 to the first preview image M6 on the region P1 'to the region P6' in the screen, respectively.

Further, after the user makes a click input to each of the switch controls S2 to S4 shown in fig. 8, as shown in fig. 9, the electronic apparatus may display a first preview image M1 in a region P9, a first preview image M5 in a region P10, and a first preview image M6 in a region P11 in the screen.

Further, when the user performs click input on the switch control S2 to the switch control S4 shown in fig. 9, the electronic device may again display the contents shown in fig. 8.

If the user makes a long press input on the screen shown in fig. 9, the electronic device may cancel displaying the toggle controls S1-S6.

It should be noted that, in the display control method provided in the embodiment of the present invention, since the first input is a sliding input on the screen, such as a multi-finger inward sliding input or a multi-finger outward sliding input, a user may trigger the electronic device to update a view angle of a preview image included in a preview image through a simpler sliding input, which is beneficial to simplifying an operation in a process of displaying the preview image by the electronic device.

Optionally, when the at least one second preview image is the same as the at least two first preview images with different view angles, and the first preview image and the second preview image both include at least two first preview images with different view angles, the at least two first preview images with different view angles are arranged in the first preview image according to a first arrangement manner, the at least two first preview images with different view angles are arranged in the second preview image according to a second arrangement manner, and the first arrangement manner is different from the second arrangement manner.

The arrangement mode of the preview images can include the display size and/or the display position of the preview images in the preview screen.

Optionally, the user performs a multi-finger outward sliding input (for example, an input that two fingers slide outward) or a click and drag input on a certain first preview image in the first preview image, and may trigger the electronic device to enlarge the display size of the first preview image in the preview image, and adaptively reduce and display the display sizes of other first preview images in the preview image; conversely, when the user performs multi-hand sliding input or clicking and dragging input on a certain first preview image in the first preview image, the electronic device may be triggered to reduce the display size of the first preview image in the preview image, and adaptively enlarge and display the display sizes of other first preview images in the preview image. Meanwhile, the electronic device may change the display positions of at least two first preview images having different view angles in the preview screen. Furthermore, the arrangement mode of at least two first preview images with different view angles in the preview picture is updated through the first input.

Illustratively, in conjunction with fig. 4, after the user makes an input of two-finger-outward-sliding for the first preview image M1 displayed in the region P1 shown in fig. 4, the electronic apparatus enlarges the display size of the first preview image M1 in the first preview screen and reduces the display sizes of the first preview images M2 to M6 in the preview screen to display the first preview images M2 to M6 in the upper right corner of the preview screen, as shown in fig. 10. The arrangement of the first preview images M1 through M6 on the preview screen (i.e., the first preview screen) shown in fig. 4 may be a first arrangement, and the arrangement of the first preview images M1 through M6 on the preview screen (i.e., the second preview screen) shown in fig. 10 may be a second arrangement. Obviously, the first arrangement is different from the second arrangement.

Further, after the user inputs (e.g., clicks) the first preview image M2 through the first preview image M6 shown in fig. 10, the electronic device may be triggered to re-display the content shown in fig. 4.

It should be noted that, in the embodiment of the present invention, because the electronic device may update the preview image through the first input of the user, so as to adjust the arrangement manner of the preview images with different view angles in the preview image, so that the arrangement manner is the arrangement manner required by the user, which is beneficial to improving the diversity of the preview images displayed by the electronic device, and prompting the electronic device to display the human-computer interaction performance in the process of displaying the preview images.

Optionally, the first preview image is a panoramic preview image synthesized according to at least two first preview images with different viewing angles, the second preview image is a panoramic preview image synthesized according to at least one second preview image, and the number of images in the at least one second preview image is multiple; wherein the panoramic parameters of the first preview picture are different from the panoramic parameters of the second preview picture, and each panoramic parameter comprises at least one of the following: viewing angle, wide angle and focal length.

Wherein the wide view angle of each panoramic preview image may be an angle less than or equal to 360 degrees.

It is understood that the larger the viewing wide angle of the panoramic preview image, the larger the viewing focal length of the panoramic preview image, and the larger the display size of the panoramic preview image in the preview screen, that is, the panoramic preview image is displayed in an enlarged manner.

Optionally, when the viewing angle of the first preview image is different from the viewing angle of the second preview image, the viewing angles of the at least two first preview images with different viewing angles are partially or completely different from the viewing angle of the at least one second preview image.

Optionally, when the preview image displayed on the electronic device is a panoramic preview image synthesized by a plurality of preview images with different view angles, that is, when the electronic device is in the three-dimensional panoramic view mode, the user performs an input of sliding up, sliding down, sliding left or sliding right on the preview image to trigger the electronic device to adjust a view angle of the panoramic preview image, that is, to adjust a view angle of the preview image.

For example, in conjunction with fig. 5, a first preview screen displayed on the screen by the electronic apparatus is a panoramic preview image in which images having viewing angles of front, rear, left, and right, respectively, are synthesized, and the viewing angle of the first preview screen is front. When the user performs a sliding input upward on the screen shown in fig. 5, the electronic device may be triggered to display a second preview screen as shown in fig. 11, where the second preview screen is a panoramic preview image in which images with viewing angles of up, down, left, and right are synthesized, respectively, and the viewing angle of the second preview screen is up, that is, an image of the sun above the user.

Optionally, in a case that a preview picture displayed on the screen by the electronic device is a panoramic preview image, the user performs two inputs of sliding outwards on the screen, which are used to trigger the electronic device to increase a view wide angle and/or a view focal length of the panoramic preview image, so as to display the panoramic preview image on the screen in an enlarged manner. And the user performs two inputs of sliding in the direction of the screen to trigger the electronic equipment to reduce the view wide angle and/or the view focal length of the panoramic preview image so as to zoom out and display the panoramic preview image on the screen.

For example, in conjunction with fig. 5, the view wide angle of the first preview screen displayed on the screen by the electronic device is denoted as view wide angle 1. A user making two directional inward sliding inputs to the screen shown in fig. 5 may trigger the electronic device to display a second preview screen as shown in fig. 12, whose viewing wide angle is denoted as viewing wide angle 2. Wherein, the view wide angle 1 is larger than the view wide angle 2.

It should be noted that, in the display control method provided in the embodiment of the present invention, when the preview image displayed on the screen of the electronic device is a panoramic preview image synthesized by a plurality of preview images with different view angles, because the electronic device supports a relatively simple sliding input by the user on the screen, the electronic device may be triggered to update the preview image, that is, to update at least one of the view angle, the view wide angle, and the view focal length of the preview image. Therefore, the method is beneficial to improving the diversity of the preview images displayed by the electronic equipment. Moreover, the user can conveniently view preview pictures with different parameters such as the view angle, the view wide angle, the view focal length and the like, thereby improving the man-machine interaction performance when the electronic equipment displays the preview images.

Optionally, step 204 in this embodiment of the present invention may be implemented by step 204 a:

and 204a, under the condition that the first preview picture comprises the image of the target object, the electronic equipment updates the preview picture displayed on the screen from the first preview picture to a second preview picture according to the target parameter.

Specifically, the first input is an input for selecting a target object, such as a click input for the target object.

Illustratively, the target object may be a person, an animal, or a scene.

Wherein the target parameters include at least one of: a display position of the image of the target object in the preview screen displayed on the screen, and a display size of the image of the target object in the preview screen displayed on the screen.

As can be understood, the user places the electronic equipment in the visual area of the tracked object and clicks to start tracking shooting, and the electronic equipment identifies the follower according to the image collected by the camera and displays the follower in a viewing interface in real time. The whole preview interface can be enlarged and the display scale of the tracking object can be adjusted by sliding the two fingers inwards, the whole preview interface can be reduced and the display scale of the tracking object can be adjusted by sliding the fingers outwards, and in addition, the user can also move the display position of the tracking object (and the icon of the target object) on the viewing interface by sliding the single finger.

Alternatively, the user may select a target object from a preview screen displayed in real time by the electronic device. The preview screen may include one or more preview images, and the user may select a target object from one of the preview images. Such as a click input by the user on an image of a target object included in the preview image. At this time, the electronic device may recognize and mark the object (i.e., the object) in the image, for example, the electronic device may frame the object in the image through a red frame.

Optionally, the user may select the target object from an image (or called a photo) already saved in the electronic device, which is not described in detail here in the embodiment of the present invention, and the electronic device may select the relevant description of the target object from the preview image in the above-mentioned embodiment.

It is understood that the target object, such as a person or an animal, in the embodiment of the present invention may move continuously in the shooting scene. Specifically, the electronic device updates the preview picture displayed on the screen from the first preview picture to the second preview picture according to the target parameter, which includes that the user manually triggers the electronic device to update the preview picture according to the target parameter, or the electronic device automatically updates the preview picture according to the target parameter.

Specifically, in the case that the preview screen displayed on the screen is a panoramic preview image, the user triggers the electronic device to update the input (such as the first input) of the preview screen according to the target parameter, which may be a sliding input of the user on the screen.

Optionally, in the process that the electronic device updates the preview screen displayed on the screen from the first preview screen to the second preview screen according to the target parameter, the electronic device may control the display size and the display position of the image of the target object in the preview screen to be unchanged. In this way, even if the target object continuously moves in the shooting scene in practice, the electronic device can recognize and track the target object through the camera, and adjust the display position and/or the display size of the image of the target object in the preview screen, so as to update the preview screen.

Optionally, in the process that the electronic device updates the preview picture displayed on the screen from the first preview picture to the second preview picture according to the target parameter, the electronic device may adjust the viewing angle along with the movement of the target object, that is, may move different cameras to acquire images at different viewing angles.

Illustratively, as shown in (a) of fig. 13, an image of an object 131 displayed on the screen by the electronic device is located at a middle position in the first preview screen, and the display size is recorded as display size 1; with the movement of the object 131 in reality, as shown in (b) in fig. 13, the image of the object 131 displayed on the screen by the electronic device is located at the middle position in the second preview screen, and the display size is written as display size 2. Wherein the display size 1 is equal to the display size 2.

Further, in conjunction with fig. 13, as shown in fig. 14, the user may make an input of sliding outward on the preview screen including the image of the object 131 to trigger the electronic device to update the display size of the image of the object 131 in the preview screen. At this time, the view mode of the electronic device may be a follow-up photographing mode to track the target object.

According to the display control method provided by the embodiment of the invention, the electronic equipment can update the preview picture displayed on the screen from the first preview picture to the second preview picture according to the target parameter, so that even if the target object moves, the electronic equipment can control the display size and/or the display position of the image of the target object in the preview picture on the screen, the display effect of the image of the target object displayed in the preview picture by the electronic equipment is better, the display size is not too large or too small, and the display position is not too close to the edge of the screen or exceeds the outside of the screen.

Optionally, in the display control method provided in the embodiment of the present invention, step 203 may be implemented by step 203 a:

step 203a, the electronic device receives a first input to the target control.

The target control comprises a three-dimensional spherical control and a pointer control positioned on the three-dimensional spherical control; the three-dimensional spherical control is used for triggering and adjusting the viewing angle of the first preview picture; the pointer control is used to adjust a viewing wide angle and/or a viewing focal length of the first preview screen.

It should be noted that each position in the three-dimensional spherical control has a mapping relationship with the viewing angle of the panoramic preview image (i.e., the preview picture), so that when the user drags or rotates the three-dimensional spherical control, the electronic device can update the viewing angle of the preview picture displayed on the screen in real time and update the viewing angle of the preview image forming the preview picture.

And an included angle between two pointers in the pointer control has a mapping relation with the view-finding wide angle and/or the view-finding focal length of the preview picture. Therefore, when the user drags one or two pointers in the pointer control, the electronic equipment can update the included angle of the pointer control in real time, the view angle of the preview image displayed on the screen and the view angle of the preview image forming the preview image.

Illustratively, as shown in (a) of fig. 15, an image of an object 151 displayed on the screen by the electronic device is located at a middle position in the first preview screen, and the display size is noted as display size 3; after the user inputs the three-dimensional spherical control 1521 in the target control 152 and the pointer control 1522 located on the three-dimensional spherical control 1521, as shown in (b) in fig. 15, the image of the object 151 displayed on the screen by the electronic device is located at the middle position in the second preview screen, and the display size is recorded as display size 4. Wherein the display size 3 is smaller than the display size 4.

It should be noted that, in the display control method provided in the embodiment of the present invention, when the preview picture displayed on the screen of the electronic device is a panoramic preview image, because the electronic device supports the three-dimensional spherical control displayed on the screen and the pointer control located on the three-dimensional spherical control by the user, the electronic device is triggered to update parameters such as a viewing angle, a viewing wide angle, a viewing focal length, and the like in the preview picture, while the three-dimensional spherical control can intuitively embody the viewing angle of the preview picture, and the pointer control can intuitively and clearly embody the viewing wide angle and the viewing focal length of the preview picture. Therefore, the interpersonal interaction performance of the electronic equipment in the process of displaying the preview image is improved, and the user can conveniently view the preview images with different viewing angles.

Optionally, the display control method provided in the embodiment of the present invention may further include, after the step 202, a step 205 and a step 206:

step 205, the electronic device receives a second input from the user.

Similarly, the description of the input mode of the second input may refer to the description of the input mode of the first input in the foregoing embodiment, and is not repeated herein in the embodiment of the present invention.

The second input may be an input that triggers the electronic device to start shooting an image or video, for example, the second input may be a user clicking on the "shoot" control 45 shown in fig. 5.

And step 206, the electronic equipment responds to the second input, collects images through all cameras in the electronic equipment, and synthesizes the collected images into a target three-dimensional panoramic image.

The electronic equipment collects images through all cameras in the electronic equipment, and the view angle of the target three-dimensional panoramic image shot by the electronic equipment is within an angle range of 360 degrees.

Optionally, the electronic device may store the target three-dimensional panoramic image when synthesizing the target three-dimensional panoramic image, for example, store the target three-dimensional panoramic image locally in the electronic device, or store the target three-dimensional panoramic image in a cloud server.

Optionally, in the case that the electronic device acquires images through all the cameras and synthesizes the acquired images into a target three-dimensional panoramic image, the preview image displayed on the screen of the electronic device may be obtained according to the images acquired by part of the cameras, for example, the preview image is obtained according to the images acquired by the front camera, the rear camera, the left camera, and the right camera.

Alternatively, the target three-dimensional panoramic image may be a photograph or a video.

In addition, the target three-dimensional panoramic image can be shot by the electronic equipment in a camera application or shot by the electronic equipment in a video chat process through a communication application.

It should be noted that, with the display control method provided in the embodiment of the present invention, since the electronic device may collect images through all the cameras thereof and synthesize the collected images into the target three-dimensional panoramic image, the electronic device may support the user to view the synthesized target three-dimensional image, that is, the user may view images of each viewing angle within 360 degrees of the shooting scene. Thus, the diversity of the images shot by the electronic equipment to the user is improved.
