At this moment, the terminal device determines a shooting scene where the virtual camera is located based on the virtual camera shooting instruction, and displays the shooting scene in real time through a flexible screen of the terminal device, specifically, when the virtual camera shooting instruction is detected, a shooting preview picture shot by the virtual camera in the shooting scene is displayed on the flexible screen based on initial parameters and an initial position of the virtual camera. It should be understood that the initial parameters and initial position of the virtual camera may be preset.
For example, the initial parameters and the initial positions may be preset fixed values, or may be adjusted before receiving the virtual image capturing instruction. As a specific embodiment, when a user plays a game in the terminal device, the user operates a virtual character to move in a game scene, and if the terminal device receives a virtual camera shooting instruction, the game scene is the shooting scene, a camera of the game is the virtual camera, a current game picture is the shooting preview picture, and the game picture may be a shooting picture of a virtual camera at a third person's view angle. It should be understood that when the game scene is shot by the virtual camera, the initial parameters and the initial position of the virtual camera may be preset, for example, the initial position of the virtual camera may be the position of the virtual character operated by the user, and the shooting angle in the initial parameters of the virtual camera may be the line-of-sight direction of the virtual character. The initial parameters and the initial position of the virtual camera are not limited here.
In S102, based on the virtual camera instruction, a bending angle of the flexible screen is monitored.
In this embodiment, when the virtual camera shooting instruction is detected, the terminal device is in a shooting mode of the virtual camera, and the bending angle of the flexible screen in the current state is monitored in real time through a sensor of the terminal device. Exemplarily, the flexible screen comprises a first display screen and a second display screen, and the bending angle refers to an included angle between the first display screen and the second display screen; generally, the bending angle ranges from 0 to 360 degrees. Exemplarily, the flexible screen is a display screen, the bending angle refers to the radian of an arc surface formed after the display screen is bent, the value range of the bending angle is 0 to 360 degrees, and the display screen is divided into a first display screen and a second display screen based on the bending line formed after the display screen is bent, which can be referred to fig. 2 specifically. Fig. 2 illustrates an application scenario diagram provided in an embodiment of the present application.

Exemplarily, the flexible screen includes a first display screen and a second display screen, the first display screen and the second display screen are bounded by a bending line shown in fig. 2, and the bending angle is an included angle between the first display screen and the second display screen; exemplarily, the flexible screen is a display screen, the display screen is bent along a bending line shown in fig. 2, the bending angle is an arc of an arc surface formed after the display screen is bent, and the display screen is divided into a first display screen and a second display screen by the bending line.
In S103, virtual imaging parameters are adjusted based on the bending angle.
In this embodiment, the virtual shooting parameters are adjusted by the monitored bending angle, so that the user can control the shooting of the virtual camera by bending the flexible screen. Specifically, the virtual shooting parameter can be adjusted according to the angle interval where the bending angle is located, that is, the virtual shooting parameter is adjusted according to whether the bending angle is one of an acute angle (the angle interval is 0 degree to 90 degrees), a right angle (the bending angle is 90 degrees), an obtuse angle (the angle interval is 90 degrees to 180 degrees), a straight angle (the bending angle is 180 degrees), a reflex angle (the angle interval is 180 degrees to 360 degrees), or a peripheral angle (the bending angle is 360 degrees). In a possible embodiment, the virtual shooting parameter is the focal length of the virtual camera, a standard angle is preset, and if the bending angle is smaller than the standard angle, the focal length of the virtual camera is shortened, which has the effect of reducing the shot picture; if the bending angle is larger than the standard angle, the focal length of the virtual camera is lengthened, and the effect of amplifying the shot picture is achieved; it should be understood that if the bending angle is equal to the standard angle, the focal length of the virtual camera is kept unchanged; it should be understood that the standard angle may be a current bending angle of the flexible screen of the terminal device when the virtual photographing instruction is received.
Specifically, the virtual shooting parameter is adjusted through the monitored bending angle, and the virtual shooting parameter can also be adjusted according to a specific numerical value of the bending angle. For example, in the above embodiment of adjusting the focal length by the bending angle, the adjustment difference for adjusting the focal length is determined based on the difference between the bending angle and the standard angle, that is, the larger the difference between the bending angle and the standard angle, the larger the adjustment range for adjusting the focal length.
In S104, a shooting preview interface is displayed on the flexible screen based on the virtual shooting parameters.

In a specific embodiment, when the terminal device runs a game, and receives the virtual camera shooting instruction, the current scene of the game is set as the shooting scene of the virtual camera, so that the virtual camera shoots a map, an environment or a virtual character of the current scene of the game; detecting a bending angle of a flexible screen of the terminal device, and adjusting virtual shooting parameters of the virtual camera based on the bending angle, such as the position, the focal length, the angle and other virtual shooting parameters of the virtual camera based on the bending angle; displaying a shooting preview interface on the flexible screen based on the adjusted virtual shooting parameters so that a user can directly observe the shooting preview interface to confirm whether the shooting preview interface is a final shooting picture; and after receiving the virtual shooting confirmation instruction, the terminal equipment shoots the current scene of the game through the virtual camera in the current state to obtain a virtual shooting screenshot of the game.
In the embodiment, a virtual camera shooting instruction is received so that the terminal equipment enters a shooting mode of a virtual camera; the terminal equipment can reduce the operation of adjusting the virtual camera through the touch screen by a user through monitoring the bending angle of the flexible screen and adjusting the virtual shooting parameters of the virtual camera based on the bending angle, so that the convenient control of the virtual camera is realized, and the convenience of shooting through the virtual camera in the terminal equipment is improved when the user uses the terminal equipment with the flexible screen.
Fig. 3 shows a flowchart for implementing adjustment of a shooting mode based on a bending angle according to a second embodiment of the present application. Referring to fig. 3, in comparison with the embodiment shown in fig. 1, the method disclosed in this embodiment includes steps S301 to S302, which are detailed as follows:
further, the virtual photographing parameters include a photographing mode; the virtual shooting parameter is adjusted based on the bending angle, including:
in S301, if the bending angle is a reflex angle, the imaging mode is adjusted to a wide-angle mode.
In this embodiment, the bending angle is a reflex angle, and the bending angle is greater than 180 degrees and less than 360 degrees. If the bending angle is a reflex angle, the shooting mode of the virtual camera is adjusted to a wide-angle mode, so that the shooting angle of a shooting picture shot by the virtual camera in the shooting scene is enlarged, and the shooting requirement of a user is met.
In a specific embodiment, if the shooting mode is the wide-angle mode, the shooting range of the wide-angle mode is determined based on the bending angle. Generally, an angle difference between the bending angle and a flat angle (180 degrees) is calculated, and a photographing range of the wide-angle mode is determined based on the angle difference; specifically, the shooting mode of the virtual camera is preset to be a normal shooting range in a normal mode, the adjustment ratio of the shooting range is determined based on the angle difference, and the shooting range in the wide-angle mode is determined based on the bending angle. And determining a specific shooting range based on the specific bending angle, and improving the shooting precision of the virtual camera controlled by the user.
In S302, if the bending angle is 360 degrees, the shooting mode is adjusted to the panoramic mode.
In the present embodiment, the bending angle is 360 degrees, i.e., a circumferential angle. Exemplarily, if the flexible screen comprises a first display screen and a second display screen, the first display screen and the second display screen of the flexible screen are in a back-to-back parallel state, and at this time, the shooting mode of the virtual camera is adjusted to be a panoramic mode; or exemplarily, if the flexible display screen is a display screen, the flexible display screen is bent to a state that two sides are overlapped and the two sides are connected end to end, and at this time, the shooting mode of the virtual camera is adjusted to be a panoramic mode. And in the panoramic mode, the virtual camera is used for shooting a panoramic image in the shooting scene so as to meet the shooting requirements of the user. Specifically, a plurality of images to be synthesized at different shooting angles are acquired through the virtual camera, and the plurality of images to be synthesized are synthesized to obtain the panoramic image.
It should be understood that the virtual camera can acquire the images to be combined at the same time, and the time interval for acquiring the images to be combined of a common camera is eliminated; and the panoramic image can be used as the shooting preview interface and displayed on the flexible screen, so that a user can obtain the experience of previewing the panoramic image in real time.
In a possible implementation manner, if the bending angle is a poor angle, that is, the bending angle is 0 to 180 degrees, the shooting mode is adjusted to a macro mode, so that the virtual camera can shoot macro images to meet the shooting requirements of the user. Generally, if the bending angle is a straight angle, i.e. the bending angle is 180 degrees, the shooting mode is adjusted to the normal mode to meet the general shooting requirements of the user. It should be understood that the angle interval of the bending angle corresponding to each shooting mode may be dynamically adjusted, for example, if the bending angle is a right angle, the shooting mode is adjusted to be the normal mode; if the bending angle is an obtuse angle, adjusting the shooting mode to be a wide-angle mode; if the bending angle is a straight angle, the shooting mode is a panoramic mode.
In this embodiment, the shooting mode of the virtual camera is adjusted by the bending angle, so that a user can control the specific shooting of the virtual camera by bending the flexible screen, and the virtual camera can meet the shooting requirements of the user in different shooting modes; meanwhile, the situation that the screen needs to be greatly slid to adjust the shooting mode to be the wide-angle mode or the panoramic mode in the prior art is avoided, and the operation convenience of controlling the virtual camera to adjust the shooting mode to be the wide-angle mode or the panoramic mode by a user is improved.
Fig. 4 shows a schematic diagram of a preview interface adjusted based on a bending angle according to a second embodiment of the present application. Referring to fig. 4, in contrast to the embodiment shown in fig. 3, the method disclosed in this embodiment includes S401, which is detailed as follows:
further, the displaying a shooting preview interface on the flexible screen based on the virtual shooting parameters includes:
in S401, if the shooting mode is the wide-angle mode or the panoramic mode, a shooting preview interface is displayed on the first display screen and the second display screen of the flexible screen together.
In this embodiment, generally, if the shooting mode is the normal mode, the shooting preview interface is only displayed on the first display screen of the flexible screen; if the shooting mode is the wide-angle mode or the panoramic mode, in order to ensure that the resolution of the shot picture is not changed, and the shooting range of the wide-angle mode or the panoramic mode is larger than that of the normal mode, the display range of the shooting preview interface needs to be expanded, that is, the shooting preview interface of the wide-angle mode or the panoramic mode is displayed on the first display screen and the second display screen of the flexible screen together.
In a specific embodiment, as shown in fig. 4, an extended display range of the second display screen is determined based on a difference between the shooting range of the wide-angle mode and the shooting range of the normal mode, and the shooting preview interface of the wide-angle mode is displayed in the display range of the first display screen and the extended display range of the second display screen, where the display range of the first display screen is generally larger than the extended display range of the second display screen. It should be understood that if the shooting mode is the panoramic mode, the shooting preview interface of the panoramic mode is displayed in the display range of the first display screen and the second display screen together.
In this embodiment, the first display screen and the second display screen of the flexible screen jointly display the shooting preview interface in the wide-angle mode or the panoramic mode, so that the user can directly observe the shooting preview interface, and the user can continuously adjust the virtual shooting parameters or determine to shoot based on the shooting preview interface.
Fig. 5 shows a schematic view of a shooting scene of a virtual camera provided in a third embodiment of the present application. Referring to fig. 5, in comparison with the embodiment shown in fig. 1, the method disclosed in this embodiment includes S501, which is detailed as follows:
further, the virtual shooting parameters include a virtual camera position; the virtual shooting parameter is adjusted based on the bending angle, including:
in S501, when a virtual camera positioning command is received, the virtual camera position is adjusted based on the bending angle.
In this embodiment, the virtual camera is at an initial position when receiving the virtual image capturing instruction, and when receiving a virtual camera positioning instruction, the virtual camera position is adjusted based on the bending angle, specifically, a target position of the virtual camera is determined based on the bending angle and the initial position, and the virtual camera is moved to the target position.
In one possible implementation, referring to fig. 5, a spatial coordinate system is established within the shooting scene of the virtual camera, a spatial adjustment axis (x-axis, y-axis, or z-axis) is determined based on the virtual camera positioning command, and the virtual camera is moved on the spatial adjustment axis based on the bending angle. Specifically, a standard angle is preset, and if the bending angle is smaller than the standard angle, the spatial coordinate value of the virtual camera on the spatial adjustment axis is increased; if the bending angle is larger than the standard angle, reducing the space coordinate value of the virtual camera on the space adjusting shaft; if the bending angle is equal to the standard angle, the space coordinate value of the virtual camera on the space adjusting axis is not adjusted.
In another possible implementation, referring to fig. 5, before adjusting the position of the virtual camera based on the bending angle, the shooting target of the virtual camera is locked, and the virtual camera always faces the shooting target; a central coordinate system is established by using the center of the shooting target, a central adjusting shaft (a horizontal angle shaft, a vertical angle shaft or a shooting distance shaft) is determined based on the virtual camera positioning instruction, and the virtual camera is moved on the central adjusting shaft based on the bending angle.
In this embodiment, the position of the virtual camera is adjusted by the bending angle, so that a user can control the specific shooting of the virtual camera by bending the flexible screen, and the virtual camera can meet the shooting requirements of the user at different virtual camera positions; meanwhile, the situation that the screen needs to be greatly slid to adjust the specific position of the virtual camera in the prior art is avoided, and the operation convenience of adjusting the position of the virtual camera by a user is improved.
Fig. 6 shows a schematic diagram of adjusting a shooting angle based on a bending angle according to a fourth embodiment of the present application. Referring to fig. 6, in comparison with the embodiment shown in fig. 1, the method disclosed in this embodiment includes step S601, which is detailed as follows:
further, the virtual photographing parameters include a photographing angle; the virtual shooting parameter is adjusted based on the bending angle, including:
in S601, the shooting angle of the virtual camera is adjusted based on the bending angle.
In this embodiment, referring to fig. 6, with the virtual camera as a center, a transverse direction and a longitudinal direction of the virtual camera are determined, where the transverse direction refers to a left-right direction in which the virtual camera performs head-up, that is, a left-right direction in a top view shown in fig. 6, and the longitudinal direction refers to an up-down direction which needs to be adjusted when the virtual camera performs head-up or head-down, that is, an up-down direction in a side view shown in fig. 6; before adjusting the shooting angle of the virtual camera based on the bending angle, the shooting angle adjustment direction (transverse direction or longitudinal direction) of the virtual camera is determined based on user operation, and the shooting angle of the virtual camera in the shooting angle adjustment direction is adjusted based on the bending angle.
For example, the adjusting the shooting angle of the virtual camera in the shooting angle adjusting direction based on the bending angle may specifically be: presetting a corresponding table of the shooting angle and the bending angle, and determining the specific numerical value of the shooting angle in the shooting angle adjusting direction based on the specific numerical value of the bending angle. The above-mentioned shooting angle of this virtual camera in this shooting angle adjustment direction based on this angle of buckling adjustment can also be specifically: presetting a standard angle, and if the bending angle is smaller than the standard angle, adjusting the shooting angle downwards in the shooting angle adjusting direction; if the bending angle is larger than the standard angle, the shooting angle is adjusted upwards in the shooting angle adjusting direction; if the bending angle is equal to the standard angle, the shooting angle is not adjusted in the shooting angle adjusting direction.
It should be understood that if the flexible screen can be bent in two different directions, the bending angles in the different directions may correspond to a transverse direction or a longitudinal direction of the shooting angle adjustment direction, and the obtaining of the bending angles of the flexible screen in the different directions may replace the operation of determining the shooting angle adjustment direction of the virtual camera based on the user operation.
In another possible implementation manner, the adjusting the shooting angle of the virtual camera based on the bending angle may specifically be: determining a shooting angle adjustment direction based on the bending angle; receiving a shooting angle adjusting direction determining instruction; and adjusting the shooting angle of the virtual camera in the shooting angle adjusting direction based on the bending angle.
Specifically, the determining the shooting angle adjustment direction based on the bending angle may specifically be: presetting a standard angle, and if the bending angle is smaller than the standard angle, changing the shooting angle adjusting direction clockwise; if the bending angle is larger than the standard angle, the shooting angle adjusting direction is changed anticlockwise; if the bending angle is equal to the standard angle, the adjusting direction of the shooting angle is not changed.
