Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. 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.

In the related art, when a terminal device with a camera function photographs an object with characters, it is often desirable that the characters in the photograph be clear, such as in a scenic spot, and in a memorial character. However, many times, the characters only have a fuzzy appearance, and the user watches the photos again, so that the user is troublesome to distinguish the characters, and the pleasure of the user in watching the pictures and going to the scenic spots is reduced.

Example one

Fig. 1 is a flowchart illustrating a photographing method according to an exemplary embodiment, where the photographing method is used in a photographing apparatus applied to a terminal having a photographing function, as shown in fig. 1, and the method includes the following steps 101 and 103:

in step 101, a scene to be photographed displayed in a preview interface is identified in real time.

The preview interface is the picture-taking scene displayed in the display range of the camera application after the camera application is opened before the shooting instruction is executed.

In step 102, when the scene to be photographed comprises the specified object is identified, the contrast of the specified object is improved on the preview interface; and/or, increasing the focus for focusing the specified object.

Here, the designated object may be an object set in advance by the user, or may be an object automatically set by the camera, such as a character object, a background building object, or the like. Here, raising the contrast of the designated object is to highlight the designated object at the position of the designated object so as to see the designated object more clearly, and similarly, raising the focus is the same principle, where the contrast is increased to such an extent that the sharpness reaches a preset value.

In step 103, the scene to be photographed is photographed according to the contrast and the focus.

As shown in fig. 2, in general, during shooting, only a face is recognized, and focusing is performed on the face (there is an original focus on the face in fig. 2).

In this embodiment, the contrast and the increased focus may make the designated object displayed more clearly in the preview interface, so that the designated object may be clearly photographed to obtain a better photographing effect.

when the designated object does not meet the requirement of the clear object, matching clear characters corresponding to specific characters in the character object through a preset character library; the character characteristics of the specific characters are the same as those of the clear characters; in the preview interface, replacing the clear characters with the corresponding specific characters; and shooting the scene to be shot in a preset interface with clear characters.

In this embodiment, the preset word library may be stored in the terminal or the remote server, and the preset word library may be classified in advance, and the common words and the non-common words are used as two sub-libraries, and in the process of matching the words, the sub-libraries of the common words may be searched first, and the non-common words may be searched and then the sub-libraries of the non-common words may be searched. Meanwhile, the preset character library can be updated on line.

The text matching of the present embodiment may be performed directly after step 101 and when it is recognized that the scene to be photographed includes the specified object, or may be performed after step 102. That is, the terminal can directly match the characters to realize the clearness of the characters on the photo.

Here, the specific character and the clear character not only require the same character, but also require the same characters, the same size, the same color, the same thickness, and other features, and therefore, the same character needs to be stored in a plurality of versions in a preset character library.

According to the embodiment, fuzzy characters can be replaced through character matching, and from the preview interface, the user can see clear characters, so that the photographing experience of the user is improved.

In one embodiment, the requirement for a clear object includes any of:

the focus can be focused on a specified object;

the definition of the designated object is greater than a predetermined value.

In this embodiment, the definition is a feature value for determining whether the designated object is clear, and the feature value may be resolution, pixel, or the like.

If the common shooting mode can not solve the problem of character shooting, character matching is used, and the defects of the common shooting mode are overcome.

In one embodiment, since clear text does not need to be displayed on the preview interface, after the clear text corresponding to the specific text is acquired from the preset text library according to the feature information, the method further includes:

shooting a scene to be shot to obtain a picture; in the photograph, the specific text is replaced with clear text.

The embodiment can replace the fuzzy characters of the photo by character matching, so that the user can see the clear characters, and the experience of watching the photo by the user is improved.

In one embodiment, in order to save power, the scene to be photographed is photographed, and obtaining the picture comprises:

and when the terminal is in the power-saving state, shooting the scene to be shot to obtain the picture.

The power saving state may include a state in which the power is lower than a preset power, for example, 10%, or a state in which a high temperature requires a low power consumption state of the device to operate, or may be a state in which some special conditions are set by a user.

In one embodiment, in order to save the space of the terminal, matching out the clear text corresponding to the specific text in the text object by using the preset text library includes:

sending an identification request carrying a character object to a server; so that the server matches clear characters corresponding to the specific characters of the character object through a preset character library; and receiving the identification response carrying the clear characters sent by the server.

In this embodiment, when the preset text library is stored on the server side, the interaction with the server is required, and the server realizes text matching.

Example two

Fig. 3 shows a flowchart of a photographing method according to an exemplary embodiment, as shown in fig. 3, the photographing method is used in a mobile terminal, and includes the following

steps

201 and 205,

in step 201, a scene to be photographed displayed in a preview interface is identified in real time.

In step 202, when the designated object is identified to be included in the scene to be photographed, the contrast of the designated object is improved on the preview interface, and the focus for focusing the designated object is increased.

It should be noted that if the definition of the text of the designated object is greater than the preset value, the process may be ended.

In step 203, when the focus cannot be focused on the designated object, clear characters corresponding to specific characters in the character object are matched through the preset character library.

Here, the specific characters are the same as the characters of the clear characters.

In step 204, the clear text is substituted for the corresponding specific text in the preview interface.

In step 205, a scene to be photographed is photographed within a preset interface with clear text.

In the embodiment, not only can the clarity of the character object be ensured through focusing and improving the contrast, but also the unclear characters can be replaced through character matching, so that the effect of clear display and shooting is achieved.

EXAMPLE III

Fig. 4 shows a flowchart of a photographing method according to an exemplary embodiment, as shown in fig. 4, the photographing method is used in a server, and includes the following

steps

301 and 305,

in step 301, a scene to be photographed displayed in the preview interface is identified in real time.

In step 302, when it is identified that the scene to be photographed includes the designated object, it is determined whether the definition of the designated object is greater than a preset value. If yes, go to step 303; if not, the process is ended.

In step 303, a clear text corresponding to the specific text in the text object is matched through a preset text library.

In step 304, when the terminal is in the power saving state, the scene to be photographed is photographed to obtain a photo.

In step 305, the specific text is replaced with clear text in the photograph.

In the embodiment, the unclear characters are replaced by the characters in the matching manner, so that the effect of clear shooting effect is achieved, the display effect of pictures is improved, and the definition of the characters is increased.
