Illustratively, continuing with reference to FIG. 3, during recording of a video, when the electronic device is tilted, a tilt of 23 is displayed.
According to the embodiment, when the electronic equipment is inclined, the inclination information of the electronic equipment is displayed, wherein the inclination information comprises an inclination angle and the like, and the display angle of the first video preview image can be conveniently adjusted by a user, so that the display angle of the second video preview image is consistent with the inclination angle of the electronic equipment.
After step 2100, step 2200 is executed to perform, in response to the first input, angle rectification processing on the first video preview image displayed on the shooting preview interface to obtain a second video preview image.
The first video preview image may be an image collected by a camera of the electronic device for a user to preview and view during recording of the video. The display angle of the first video preview image is inconsistent with the inclination angle of the electronic device. The display angle of the second video preview image is consistent with the inclination angle of the electronic equipment.
In some embodiments of the present application, the first input may be a rotational input to the orthotic control; performing angle correction processing on the first video preview image displayed on the shooting preview interface to obtain a second video preview image, which may include: and acquiring the rotation angle of the correction control, and rotating the first video preview image according to the rotation angle of the correction control to obtain a second video preview image. It will be appreciated that the user may rotate the orthotic control 401 as desired.
For example, please refer to fig. 4, which is a schematic diagram of another shooting preview interface according to an embodiment of the present application. Specifically, after the real-time correction function is started, the correction control 401 is displayed on the shooting preview interface, a user can rotate the correction control 401 according to actual needs, when the rotation angle of the first video preview image meets the user requirements, the rotation of the correction control 401 is stopped, that is, the first input to the correction control is finished, and in response to the first input, the first video preview image is rotated according to the rotation angle of the correction control, so that the second video preview image is obtained. In addition, an operation identifier 402 is also displayed on the shooting preview interface, and a user can perform angle rectification processing on the first video preview image according to the operation identifier 402. It should be noted that the operation identifier in this embodiment is a text, a symbol, an image, and the like for indicating information, and a control or another container may be used as a carrier for displaying information, including but not limited to a text identifier, a symbol identifier, and an image identifier.
In further embodiments of the present application, before receiving the first input of the user to the shooting preview interface, the method may further include: receiving a second input of the user; acquiring a correction step size in response to the second input; the angle correction processing is performed on the first video preview image displayed on the shooting preview interface to obtain a second video preview image, and may further include: and rotating the first video preview image according to the rotation angle corresponding to the correction step length to obtain a second video preview image.
In this embodiment, the second input may be an input for selecting a corrective step size. The second input may be, for example, a click input of a user on the target control, or a click input of a user on the target area, or a specific gesture input by the user, which may be determined according to actual usage requirements, and is not limited in this embodiment of the application.

In this embodiment, the rectification step size may be used to limit the rotation amplitude of the first video preview image. When a first input of a user to the first video preview image is received, namely when the user triggers the angle correction processing to the first video preview image, the first video preview image is rotated according to a rotation angle corresponding to the correction step length. It should be noted that, the user may select the correction step size according to actual needs.
In this embodiment, different correction step lengths correspond to different rotation angles. The larger the correction step length is, the larger the corresponding rotation angle is, and the larger the adjustment amplitude is. The smaller the correction step length is, the smaller the corresponding rotation angle is, and the smaller the amplitude of each adjustment is. The treatment efficiency can be improved by selecting a larger correction step length. And the correction precision can be improved by selecting a smaller correction step length.
In this embodiment, the correction step size may be determined by the correction gear selected by the user. The correction gear may be preset. For example, a plurality of correction gears may be preset, and different correction gears correspond to different correction step sizes. For example, four correction gears are set, including gear 1, gear 2, gear 3, and gear 4, where the correction step size corresponding to gear 1 is 60 °, the correction step size corresponding to gear 2 is 30 °, the correction step size corresponding to gear 3 is 15 °, and the correction step size corresponding to gear 4 is 10 °. It should be noted that the number of the correction gears and the correction step size corresponding to each correction gear may be set according to the actual needs of the user, and this is not particularly limited in the embodiment of the present application.
For example, please refer to fig. 5, which is a schematic diagram of selecting a correction step size according to an embodiment of the present application. Specifically, after the real-time correction function is started, a selection control 501 of a correction gear is also displayed on the shooting preview interface, and in response to a click operation of the selection control 501 by a user, a plurality of correction gears are displayed, such as a gear 1 (correction step size is 60 °), a gear 2 (correction step size is 30 °), a gear 3 (correction step size is 15 °), and a gear 4 (correction step size is 10 °); then, in response to a second input of the user to the gear 4, a correction step size corresponding to the gear 4 is obtained. Then, when the electronic device is tilted to the right, the user adjusts the display angle of the first video preview image by rotating the rectification control 502. In one possible approach, the user rotates the rectification control 502 clockwise, and the first video preview image may rotate in real time as the rectification control 502 rotates, for example, when the first video preview image rotates by an angle (10 °) of one rectification step, the first video preview image stops rotating after synchronously rotating by 10 °. In another possible approach, the user rotates the rectification control 502 clockwise, and after the rotation is assumed to be performed by an angle (10 °) of one rectification step, the rectification is triggered, so that the first video preview image is rotated clockwise by 10 °, that is, the first video preview image may be rotated after the rotation of the rectification control is completed. And then, the user can continue to rotate the first video preview image until the display angle of the first video preview image meets the requirements of the user, namely, the second video preview image is obtained.
In the embodiment of the application, the user can select the correction step length according to actual needs, and rotate the first video preview image according to the rotation angle corresponding to the correction step length to obtain the second video preview image, so that the angle correction processing is performed on the first video preview image according to the larger correction step length, the processing efficiency can be improved, the angle correction processing is performed on the first video preview image according to the smaller correction step length, the correction precision can be improved, different requirements of the user can be met, and the operation is more flexible.
In some optional embodiments, the corrective step size comprises a first corrective step size and a second corrective step size, the first corrective step size being greater than the second corrective step size; rotating the first video preview image according to the rotation angle corresponding to the correction step length to obtain a second video preview image, comprising: rotating the first video preview image according to the first correction step length to obtain a third video preview image; and rotating the third video preview image according to the second correction step length to obtain the second video preview image.
For example, in the case that the electronic device is inclined to a greater extent, that is, the first video preview image is inclined to a greater extent, a first correction step may be selected first, for example, gear 2 (corresponding to a correction step of 30 °), the user rotates the correction control, and after rotating an angle (30 °) of one correction step, the user triggers correction to rotate the first video preview image by 30 °, and it is understood that the first video preview image may also rotate synchronously with the user operation until the rotation angle of the first video preview image reaches the angle (30 °) of one correction step, and then stop rotating. After the display angle of the first video preview image is close to the inclination angle of the electronic device, a second smaller correction step length can be selected, for example, a gear 4 is selected (the corresponding correction step length is 10 °), the user rotates the correction control, after rotating the angle (10 °) of one correction step length, correction is triggered, and the first video preview image is rotated by 10 °, it can be understood that the first video preview image can also synchronously rotate along with the operation of the user until the rotation angle of the first video preview image reaches the angle (10 °) of one correction step length, and then the rotation is stopped; and then, the user can continue to rotate the first video preview image until the display angle of the first video preview image meets the requirements of the user, namely, the second video preview image is obtained.
In the embodiment of the application, when the first video preview image is subjected to angle correction processing according to the correction step length, when the first preview video image is inclined seriously, a larger correction step length can be selected for adjustment, and then a smaller correction step length can be selected for fine adjustment, so that the correction precision can be improved while the processing efficiency is ensured.
In this embodiment, the angle correction may be performed on the first video preview image with reference to the photographic subject in the first video preview image. This will be explained in detail below.
In some embodiments of the present application, the first video preview image includes a target object therein; before the receiving of the first input of the user to the shooting preview interface, the method may further include: step 3100-step 3200.
Step 3100, receiving a third input to the target object from the user.
In the present embodiment, the target object may be a photographic object in the first video preview image. For example, the third input may be a click input of the user on the target area, and the click input in this embodiment may be a single click input, a double click input, or any number of times of click inputs, and may also be a long-press input or a short-press input.
Step 3200, displaying an adjusted coordinate system corresponding to the target object in response to the third input.
In this embodiment, the adjustment coordinate system may indicate a degree of tilt of the target object in the first video preview image. The adjustment coordinate system includes a first axis (x-axis), a second axis (y-axis), and a tilt indicator indicating a tilt direction of the target object. In this embodiment, the x-axis and the y-axis of the adjusted coordinate system are used to indicate the tilt direction of the electronic device, the extension direction of the x-axis coincides with the extension direction of a first sidewall of the electronic device, the extension direction of the y-axis coincides with the extension direction of a second sidewall of the electronic device, and the first sidewall and the second sidewall are two adjacent sidewalls of the electronic device. It should be noted that the oblique mark in the embodiment of the present application is a text, a symbol, an image, and the like for indicating information, and a control or another container may be used as a carrier for displaying information, including but not limited to a text mark, a symbol mark, and an image mark.
For example, as shown in fig. 6, the extending direction of the x-axis coincides with the extending direction of the upper and lower frames of the electronic device, and the extending direction of the y-axis coincides with the extending direction of the left and right frames of the electronic device. The tilt flag 603 indicates the tilt direction of the target object 601.
When the electronic device is tilted, the tilt direction of the tilt indicator of the adjustment coordinate system matches the tilt direction of the target object. In the case where the electronic device is not tilted, the tilt indicator of the adjustment coordinate system may coincide with the first axis (x-axis) or coincide with the second axis (y-axis).
In this embodiment, in the process of recording a video, when the electronic device is tilted, the display angle of the first video preview image changes relative to the electronic device, and the first video preview image acquired by the electronic device is tilted, that is, the shooting object in the first video preview image is also tilted. Based on this, in response to a third input to the target object by the user, the adjustment coordinate system of the target object is displayed, so that the user can intuitively observe the inclination direction of the target object, and perform the angle correction processing on the first video preview image according to the change of the display angle of the target object with the target object as a reference, and can adjust the accuracy of the correction.
In some optional embodiments, displaying the adjusted coordinate system corresponding to the target object may include: acquiring the inclination direction of the electronic equipment through a first sensor; determining the inclination direction of the target object according to the inclination direction of the electronic equipment; and displaying an adjusting coordinate system corresponding to the target object according to the inclination direction of the target object. The first sensor is used for detecting the tilt direction of the electronic device, and the first sensor may be a gyroscope, for example.
In this embodiment, in the process of recording a video, when the electronic device is tilted, the display angle of the first video preview image changes relative to the electronic device, and the first video preview image acquired by the electronic device is tilted, that is, the shooting object in the first video preview image is also tilted. Based on this, from the tilt direction of the electronic device, the tilt direction of the target object can be determined. For example, the electronic device is tilted to the right, the first video preview image is tilted to the left with respect to the electronic device, and the target object of the first video preview image is also tilted to the left.
In this embodiment, displaying the adjusted coordinate system corresponding to the target object may be displaying the adjusted coordinate system corresponding to the target object in the first area. The first region may be a region near the target object. The first region may be determined based on a position of the target object in the first video preview image.
For example, please continue to refer to fig. 6, which is a schematic diagram of an adjusted coordinate system of a target object according to an embodiment of the present application. Specifically, when the electronic device is tilted to the left, the first video preview image is tilted to the right with respect to the electronic device, and the target object 601 of the first video preview image is also tilted to the right, and in response to a third input to the target object 601 by the user, an adjustment coordinate system 602 is displayed in the vicinity of the target object 601, the tilt direction of a tilt indicator 603 of the adjustment coordinate system 602 indicates the tilt direction of the target object 601, the extension direction of the x-axis of the adjustment coordinate system 602 coincides with the extension direction of the bottom side 604 of the electronic device, and the extension direction of the y-axis of the adjustment coordinate system 602 coincides with the extension direction of the side 605 of the electronic device.

In this embodiment, the first input may be an input for rotating the tilt indicator toward the first axis, or may be an input for rotating the tilt indicator toward the second axis.
In this embodiment, the rotation parameters of the tilt indicator may include a rotation direction and a rotation angle. The rotating the first video preview image according to the rotation parameter may be rotating the first video preview image according to a rotation direction and a rotation angle. The direction of rotation may be the direction of rotation of the tilt indicator. In the case that the tilt indicator rotates toward the first axis, the rotation angle may be an angle between the tilt indicator and the first axis. In the case that the tilt indicator rotates toward the second axis, the rotation angle may be an angle between the tilt indicator and the second axis.
Illustratively, continuing to refer to fig. 6, after the shooting preview interface displays the adjustment coordinate system 602, if the user moves the tilt indicator toward the x-axis, the first video preview image is rotated clockwise according to the angle between the tilt indicator and the x-axis, so that the display angle of the first video preview image is consistent with the direction of the electronic device when the electronic device is landscape. And if the user moves the inclined mark to the y axis, rotating the first video preview image along the anticlockwise direction according to the included angle between the inclined mark and the y axis, so that the display angle of the first video preview image is consistent with the direction of the electronic equipment during vertical screen display.
