Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of 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 foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a multimedia data processing method for use in a user equipment that can interact with a user, as shown in fig. 1, according to an exemplary embodiment, the multimedia data processing method comprising the following steps.
In step S11, in response to an on command to 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 states of the mirror switch include an on state or an off state.
The multimedia data processing method in the embodiment of the disclosure can be applied to user equipment such as mobile phones and computers, and a user can acquire and process multimedia data through interaction with the user equipment. Typically, the user device has two cameras, a front camera and a rear camera, respectively, the data captured by the cameras, i.e. the background of the preview interface. The background in the preview interface corresponding to the rear camera is consistent with the picture observed by the human eye, and the background in the preview interface corresponding to the front camera is generally mirror image with the picture observed by the human eye, so that a user can start the front camera or the rear camera according to the self requirement.
One or more function switches or controls can be further included in the preview interface, and a user can process data captured by the camera through corresponding operation of 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 the user may switch the state of the mirror switch, so as to control whether the user device performs mirror-turning on the data captured by the camera.
As shown in fig. 2, in an exemplary embodiment, the screenshot of the preview interface corresponding to the front camera may be seen, where the background in the preview interface is mirrored with the image observed by the human eye, and the text is difficult to be identified due to the mirror image turning, and the screenshot further includes a "turning" function control capable of controlling the lens switching, a "speed changing" control capable of controlling the speed change of the shot data, a "countdown" function control capable of controlling the countdown shooting, a "mirror image" function control capable of controlling the mirror image turning of the shot data, a proportional adjustment function control capable of controlling the proportion of the shot data, and a function switch or control for controlling the flash switch.
In the disclosure, the lens opening instruction received by the user equipment includes an opening instruction for the rear camera and an opening instruction for the front camera, and in response to the opening instruction for the rear camera, a preview interface corresponding to the rear camera is displayed, and the mirror switch is set to be gray, that is, the state of the mirror switch is closed and cannot be modified at this time, in this state, if a clicking operation for the mirror switch control is received, the user can be prompted that the rear camera temporarily does not support mirror.
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 restored to the state of the mirror switch when the front camera is started last time, and the state of the mirror switch is defaulted to be the starting state under the condition that the front camera is started for the first time.
The shot opening instruction may be a clicking operation of a shot switching control in the current page, or may be any preset gesture operation in the current page, which is not particularly limited.
In the preview interface, different states of the mirror switch can be embodied according to different display forms of the mirror switch control. For example, the mirror switch may be in the form of a sliding switch button, which indicates that the state of the mirror switch is on when the button is near the left side, whereas indicates that the state of the mirror switch is off when the button is near the right side. Alternatively, the mirror switch may be in the form of an icon, where the icon of the mirror switch is colored, the state of the mirror switch is an on state, whereas the icon of the mirror switch is a gray scale, where the state of the mirror switch is an off state, and so on, and is not specifically limited.
In some scenes, when a front camera is started to shoot the text object, if the shot data mirror image shows that the content of the shot data mirror image is difficult to be recognized by a user, in this case, text recognition can be performed on a background captured by the front camera in a preview interface, if the background includes a text area, the current state of a mirror image switch is obtained, if the current state of the mirror image switch is an on state, mirror image prompt information is displayed, the mirror image prompt information is used for prompting the user to switch the state of the mirror image switch, and the state of the switch is switched to an off state.
In step S12, in response to the photographing operation, photographing data is acquired using the front-end 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 photographing operation through interaction with a user device, so that photographing data, which may be video or image, is obtained by using a front camera, which is not particularly limited.
In one implementation, a capture control may be included in the preview interface, and a user may begin or end the capture process by different preset operations on the capture control. The specific steps may include, in response to a first preset operation on a video shooting control in a preview interface, acquiring shooting data from a last detection of a second preset operation to a detection of a current first preset operation by using a front camera, and simultaneously acquiring a target state of a mirror switch corresponding to the shooting data. Wherein 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 again on the shooting control, the end operation may be a single click operation again or a long press operation again on the video shooting control, and the like, which is not particularly limited.
In step S13, if the target state is the on state, the shooting data is regarded as target multimedia data.
In this step, if the state of the mirror switch control is an on state, which indicates that the video mirror is turned on, the shooting data obtained by shooting with the front camera may be used as the target multimedia data, that is, the direction of the target multimedia data is consistent with the direction of the preview interface, and the target multimedia data is mirror image with the image actually observed by the human eye.
In step S14, if the target state is the off state, the shot data is mirror-flipped, and the mirror-flipped shot data is used as the target multimedia data.
In this step, if the state of the mirror switch control is the off state, it indicates that the video mirror is turned off, and mirror-turning needs to be performed on the shooting data obtained by shooting with the front camera, so as to obtain the target multimedia data, that is, the target multimedia data is mirror-imaged with the preview interface, and is consistent with the direction of the picture actually observed by the human eye.
In the shooting data, the background captured by the front-end camera is included, and if the target state is the closed state, mirror image overturning can be carried out on the background captured by the front-end camera to obtain target multimedia data. In one implementation manner, whether the background of the acquired shooting data includes a text region or not can be judged first, if the background includes the text region, the text region in the background is subjected to mirror image overturn so as to obtain a mirror image overturn background, and then the mirror image overturn background is used as target multimedia data. That is, only the text region with higher recognition difficulty after mirror image in the background is subjected to mirror image overturning, so that on one hand, the recognition difficulty of the text in the target multimedia data is reduced, and on the other hand, the calculated amount during mirror image overturning can be reduced. If the background layer does not include the text region, the image of the whole background layer can be turned over, and the shooting data after the image turning over is used as target multimedia data. The text includes words, numbers, letters or symbols.
The shooting data can also comprise a foreground, wherein the foreground comprises one or more special effect layers added by a user for a background captured by a front camera in a preview interface, such as a color matching filter, a magic expression, a dynamic sticker and the like, and the special effect layers are not particularly limited.
In one implementation manner, under the condition that the target state is the closed state, whether the acquired shooting data comprises a foreground or not can be judged, if yes, whether the foreground comprises a text region or not is judged, if the foreground comprises the text region, in one case, image overturning is not required to be carried out on the foreground, the foreground and the background after the image overturning are used as target multimedia data, or in another case, other foreground regions except the text region can be overturned to obtain the foreground after the image overturning, and then the foreground after the image overturning and the background after the image overturning are used as target multimedia data. Therefore, characters in the foreground cannot be overturned by the mirror image, and the identification of the text in the target multimedia data is facilitated. If the foreground does not include the text region, the whole foreground can be subjected to mirror image overturning, and the foreground after mirror image overturning and the background after mirror image overturning are used as target multimedia data.
In the present disclosure, the photographing operation may include a pause operation and a continuous photographing operation, so that the acquired photographing data includes a plurality of segmented photographing data, and then, for each segmented photographing data, the segmented target multimedia data corresponding to the segmented photographing data may be determined according to the target state of the mirror switch corresponding to the segmented photographing data, and then, the plurality of segmented target multimedia data corresponding to the plurality of segmented photographing data are spliced to obtain the target multimedia data.
In one implementation, when the front camera does not currently take video, the state of the mirror switch may be adjusted in response to a switching operation of the mirror switch. That is, when the front camera does not start shooting or pauses shooting, the state of the mirror switch can be adjusted at any time, and the target state of the mirror switch corresponding to the shooting data is changed, so that whether the shooting data needs to be subjected to mirror image overturning is determined, and for the shooting data comprising a plurality of segmented shooting data, mirror image overturning of any one or more segmented shooting data can be realized without affecting other segmented shooting data, so that the flexibility of multimedia data processing can be improved.
When the mirror switch is switched from the on state to the off state, the user can be prompted that the self-timer is turned left and right on the editing page, and when the mirror switch is switched from the off state to the on state, the user can be prompted that the self-timer picture is consistent with the shooting direction. In this way, the user is more convenient to understand the function of the mirror image switch control.
In one implementation, after the target multimedia data is obtained, an editing page of the target multimedia data may be displayed, and editing is performed on the target multimedia data in response to an operation on an editing control in the editing page. The editing controls can comprise magic expression controls, addition of music controls, image beautifying controls and the like, and the editing controls can provide rich functions so as to meet the use requirements of users.
As shown in fig. 3, when the state of the mirror switch is in the on state, the text is mirrored because the mirror-inverted is not performed, and as shown in fig. 4, when the state of the mirror switch is in the off state, the text is normally displayed because the mirror-inverted is performed.
From the above, it can be seen that, according to the technical scheme provided by the embodiment of the present disclosure, according to the state of the mirror switch corresponding to the shot data, it is determined whether to need to mirror-turn the shot data shot by the front camera, and if the mirror switch is in the off state, the shot data is mirror-turned to obtain the target multimedia data. Therefore, the image turning of the shot data is carried out, the self-contained function of the user equipment is not needed, the application scene is wider, the operation path of the user is shortened, and the method is convenient and fast.
