Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a multimedia data processing method according to an exemplary embodiment, which is used in a user equipment, and the user equipment can interact with a user, as shown in fig. 1, and the multimedia data processing method includes the following steps.
In step S11, in response to an opening instruction for the front camera, a preview interface corresponding to the front camera is displayed, and the preview interface displays a mirror switch capable of switching states, where the state of the mirror switch includes an open state or a closed state.
The multimedia data processing method in the embodiment of the disclosure can be applied to user equipment such as a mobile phone and a computer, and a user acquires multimedia data and processes the multimedia data through interaction with the user equipment. Typically, the user device has two cameras, a front camera and a rear camera, and the data captured by the cameras is the background of the preview interface. The background in the preview interface corresponding to the rear camera is consistent with the picture observed by human eyes, the background in the preview interface corresponding to the front camera is usually a mirror image of the picture observed by human eyes, and a user can start the front camera or the rear camera according to the requirement of the user.
One or more function switches or controls can be further included in the preview interface, and the user can process the data captured by the camera through corresponding operations on the function switches or controls. For example, the preview interface may include a mirror switch, where the state of the mirror switch includes an on state or an off state, and a user may switch the state of the mirror switch, so as to control whether the user equipment performs mirror inversion on data captured by the camera.
As shown in fig. 2, in an exemplary embodiment, it can be seen that a screenshot of a preview interface corresponding to a front-facing camera, a background in the preview interface is a mirror image of a picture observed by human eyes, and text is difficult to recognize due to mirror image inversion, and in the upper right of the preview interface, the screenshot preview interface further includes a "flip" function control that can control lens switching, a "shift" control that can control shot data shift, a "countdown" function control that can control countdown shooting, a "mirror" function control that can control shot data mirror inversion, a ratio adjustment function control that can control shot data ratio, and a function switch or control that controls a flash switch.
In this disclosure, a lens opening instruction received by a user equipment includes an opening instruction for a rear camera and an opening instruction for a front camera, and in response to the opening instruction for the rear camera, a preview interface corresponding to the rear camera is displayed, and a mirror switch is grayed, that is, the state of the mirror switch is off and cannot be modified, and in this state, if a click operation on a mirror switch control is received, a user can be prompted that "the rear camera temporarily does not support mirroring".
And if the lens opening instruction is an opening instruction for the front camera, displaying a preview interface corresponding to the front camera. If the starting instruction of the front camera is a re-starting instruction, the state of the mirror switch can be recovered to the state of the mirror switch when the front camera is started last time, and the state of the mirror switch is acquiescent to be the starting state under the condition that the front camera is started for the first time.
The lens opening instruction may be a click operation on a lens switching control in the current page, or may be any preset gesture operation in the current page, and is not limited specifically.
In the preview interface, different states of the mirror image switch can be embodied according to different display forms of the mirror image switch control. For example, the mirror switch may be in the form of a sliding switch button, which indicates that the mirror switch is in an on state when the button is close to the left side, and conversely, indicates that the mirror switch is in an off state when the button is close to the right side. Or, the mirror switch may be in the form of an icon, and when the icon of the mirror switch is colored, the state of the mirror switch is represented as an on state, whereas when the icon of the mirror switch is a gray scale, the state of the mirror switch is represented as an off state, and so on, which is not limited in particular.
In some scenes, a shot object comprises a character object, when a front camera is started to shoot the character object, if the shot data is displayed in a mirror image mode, the content of the shot data is difficult to identify by a user, under the condition, text identification can be carried out on a background captured by the front camera in a preview interface, if the background comprises a text area, the current state of a mirror image switch is obtained, if the current state of the mirror image switch is in the on state, mirror image prompt information is displayed and used for prompting the user to switch the state of the mirror image switch, and the state of the mirror image switch is switched to the off state.
In step S12, in response to a photographing operation, photographing data is acquired using the front camera, and a target state of a mirror switch corresponding to the photographing data is acquired.
In the present disclosure, a user performs a corresponding shooting operation through interaction with a user device, so as to obtain shooting data by using a front-facing camera, where the shooting data may be a video or an image, and is not limited specifically.
In one implementation, a shooting control may be included in the preview interface, and a user may start or end a shooting process through different preset operations on the shooting control. The method comprises the specific steps that in response to a first preset operation on a video shooting control in a preview interface, shooting data between the last detection of a second preset operation and the detection of the current first preset operation are obtained by using a front-facing camera, and meanwhile, a target state of a mirror image switch corresponding to the shooting data is obtained. The first preset operation may include a pause operation or an end operation, and the second preset operation may include a continue operation or a start operation.
For example, the start operation may be a single-click operation or a long-press operation on the shooting control, the pause operation may be a double-click operation on the shooting control, the continue operation may be a double-click operation on the shooting control again, and the end operation may be a single-click operation or a long-press operation on the video shooting control again, and the like, which is not limited specifically.
In step S13, if the target state is the on state, the shooting data is set as the target multimedia data.
In this step, if the state of the mirror image switch control is the on state, it indicates that the video mirror image is turned on, and the shooting data obtained by shooting with the front camera may be used as the target multimedia data, that is, the target multimedia data is consistent with the direction of the preview interface and is a mirror image of the picture actually observed by the human eyes.
In step S14, if the target state is the off state, the image data is mirror-flipped, and the mirror-flipped image data is used as the target multimedia data.
In this step, if the state of the mirror image switch control is the off state, it indicates that the video mirror image is turned off, and the shot data shot by the front camera needs to be mirror-inverted to obtain the target multimedia data, that is, the target multimedia data is mirror-imaged with the preview interface and is in accordance with the direction of the picture actually observed by the human eyes.
And if the target state is the closed state, mirror image overturning can be carried out on the background captured by the front camera to obtain target multimedia data. In an implementation manner, it may also be determined whether the background of the acquired shooting data includes a text region, if the background includes the text region, mirror image flipping is performed on the text region in the background to obtain a background after mirror image flipping, and then the background after mirror image flipping is used as the target multimedia data. That is to say, only the text region with high identification difficulty after mirroring in the background is mirrored and flipped, so that on one hand, the identification difficulty of the text in the target multimedia data is reduced, and on the other hand, the calculation amount during mirroring flipping can be reduced. If the background layer does not include the text area, the image inversion can be performed on all the backgrounds, and the shot data after the image inversion is used as target multimedia data. The text includes words, numbers, letters, or symbols.
In the shooting data, a foreground may be further included, where the foreground includes one or more special effect layers added by the user to the background captured by the front camera in the preview interface, such as a color-mixing filter, a magic expression, a dynamic sticker, and the like, which is not limited specifically.
In one implementation, when the target state is the closed state, it may be determined whether the acquired shooting data includes a foreground, if so, it may be determined whether the foreground includes a text region, and if the foreground includes the text region, then, in one case, the foreground may not be mirror-flipped, and the foreground and the background after mirror-flipping may be used as the target multimedia data, or, in another case, other foreground regions except the text region may be flipped to obtain the foreground after mirror-flipping, and then, the foreground after mirror-flipping and the background after mirror-flipping may be used as the target multimedia data. Therefore, characters in the foreground cannot be turned over by the mirror image, and the identification of texts in the target multimedia data is facilitated. If the foreground does not include the text area, the image turning can be performed on all the foreground, and the foreground after the image turning and the background after the image turning are used as target multimedia data.
In this disclosure, the shooting operation may include a pause operation and a continue shooting operation, such that the obtained shooting data includes a plurality of pieces of segmented shooting data, and then, for each piece of segmented shooting data, the segmented target multimedia data corresponding to the piece of segmented shooting data may be determined according to a target state of a mirror switch corresponding to the piece of segmented shooting data, and then, the plurality of segmented target multimedia data corresponding to the plurality of pieces of segmented shooting data may be spliced to obtain the target multimedia data.
In one implementation, the state of the mirror switch may be adjusted in response to a switching operation of the mirror switch in a case where the front-facing camera is not currently performing video shooting. That is to say, when the front camera does not start to shoot or pause shooting, the state of the mirror image switch can be adjusted at any time, and the target state of the mirror image switch corresponding to the shot data is changed, so that whether the shot data needs to be subjected to mirror image overturning or not is determined.
When the mirror switch is switched from the off state to the on state, the user can be prompted that the picture is closed and the self-timer picture is turned left and right on the editing page. In this way, the user can more conveniently understand the functions of the mirror switch control.
In one implementation, after the target multimedia data is obtained, an editing page of the target multimedia data can be displayed, and the target multimedia data is edited in response to an operation on an editing control in the editing page. The editing controls can comprise magic expression controls, music adding controls, image beautifying controls and the like, and the editing controls can provide rich functions and further meet the use requirements of users.
As shown in fig. 3, the screenshot of the editing page of the target multimedia data is a screenshot of the editing page of the target multimedia data when the state of the mirror switch is the on state, and the text is a mirror image because the mirror image is not turned over, as shown in fig. 4, the screenshot of the editing page of the target multimedia data is a screenshot of the editing page of the target multimedia data when the state of the mirror switch is the off state, and the text is normally displayed because the mirror image is turned over.
As can be seen from the above, according to the technical scheme provided by the embodiment of the disclosure, it is determined whether mirror image inversion needs to be performed on the shot data shot by the front camera according to the state of the mirror image switch corresponding to the shot data, and when the mirror image switch is in the off state, the mirror image inversion is performed on the shot data to obtain the target multimedia data. Therefore, the shot data is subjected to mirror image turning without depending on the self-carried functions of the user equipment, the application scene is wider, the operation path of the user is shortened, and the method is convenient and fast.
