Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

As shown in fig. 3, a first embodiment of the present application provides a method for displaying a zoomed image, where the method includes the following steps:

step 301, acquiring a target to be processed from a displayed first picture;

step 302, receiving a first zooming instruction for the target;

step 303, zooming the target according to the first zooming instruction, and generating a second picture;

step 304, displaying the second picture.

Specifically, step 301 is triggered when the current interface is monitored to display a picture. In this embodiment, the picture may be a picture or a photo in an album of the mobile terminal, may also be a picture or a photo currently taken by the camera application, and may also be a picture or a photo opened by another application. For example, a photo in a WeChat friend circle that the user is browsing.

Further, in the embodiments of the present application, the types of the object include: characters, scenery, buildings, plants, animals.

That is, when it is detected that the current interface of the mobile terminal is operated and a picture is displayed, a person, a scene, a building, a plant, etc. in the picture are recognized. The process of identifying different target types is relatively similar. Taking the recognition of people as an example, people in the picture are mainly determined by recognizing human faces. The human face recognition process can detect the human face by measuring the distance between eyes, cheekbones, chin and the like by using 80 nodes or punctuations distributed on the human face from low to high. The face recognition algorithm includes but is not limited to: template matching based methods, singular value feature based methods, subspace analysis methods, local preserving projections or principal component analysis methods, and the like. In a specific implementation manner of this embodiment, the performing face recognition on the picture may specifically include: training according to preset corpus data to obtain a human face feature model, wherein the corpus data is the facial features of a large number of people; and detecting the face contained in the picture according to the obtained face feature model. The process of recognizing scenes, buildings and plants is similar to the process of recognizing human faces, and the process is not repeated one by one.

After the target to be processed is determined, a first zooming instruction for the target is received, the target is zoomed in or zoomed out according to the first zooming instruction, a second picture is generated, the second picture is displayed as a current interface, and a user can view the zoomed in or zoomed out specific target.

Further, the first zoom instruction may be one or a combination of a touch press instruction, a touch slide instruction, and a shake instruction. For example, shaking the mobile terminal is set as an enlargement instruction, and clicking the display screen of the mobile terminal is set as a reduction instruction.

Further, the magnification or reduction factor can be set for different parameters of the zoom instruction. For example, setting a shake once mobile terminal means amplifying an object by 1 time, setting a shake twice mobile terminal means amplifying an object by 2 times, and setting a time interval between the first shake and the second shake mobile terminal not to exceed a preset time threshold, and if the time interval exceeds the time threshold, assuming that the number of shakes is 1, then only amplifying the object by 1 time.

Further, in step 304, when the second picture is displayed, the second picture may be automatically moved to the center of the screen for display.

And receiving an instruction of shaking the mobile terminal once by the user. And amplifying the face in the first picture to generate a second picture as shown in fig. 4b, and displaying the amplified face picture at the central position of the display screen.

Further, in an actual application scene, when a user turns over a certain photo, the photo of the user in front of the Tiananmen square is displayed. The user wants to look through his expression. When the technical scheme of the embodiment of the application is adopted, the method is realized through the following steps:

step 1, monitoring that a current interface displays pictures in an album;

step 2, analyzing the figure in the picture, carrying out face recognition on the figure, and determining the face as a target to be processed;

step 3, receiving a shaking instruction;

step 4, amplifying the human face in the picture and generating an amplified picture;

and 5, displaying the amplified human face picture.

Therefore, the user can see the amplified human face picture without performing touch operation on the picture for many times, the steps of user operation are simplified, the satisfaction degree of the user is improved, and interesting use experience is brought to the user.

Optionally, as shown in fig. 5, after step 304, the method for displaying a zoomed picture further includes the following steps:

step 501, receiving an editing instruction for the second picture;

step 502, the second picture executes a result corresponding to the editing instruction.

Specifically, the editing instruction may be an operation instruction for performing cutting, rotation, and the like on the second picture, and correspondingly, according to the editing instruction, the second picture is edited correspondingly, and the edited second picture is displayed.

Further, the editing instruction may also be an instruction for triggering other image editing classes, for example, according to a touch operation of a user, the second image is jumped to the beauty show so as to perform beauty processing on the second image.

According to the image zooming display method, the target to be processed is obtained from the displayed first image, the first zooming instruction for the target is received, the target is zoomed according to the first zooming instruction, the second image is generated, and the second image is displayed. Therefore, the picture zooming display method in the embodiment avoids a series of complex operation processes such as touch pressing operation and moving operation on the screen of the mobile terminal, improves user experience, and enhances the interestingness of the user in using the mobile terminal.

601, acquiring a target to be processed from a displayed first picture;

step 602, receiving a first zoom instruction for the target;

step 603, zooming the target according to the first zooming instruction, and generating a second picture;

step 604, displaying the second picture;

step 605, receiving a second zooming instruction for the target;

step 606, determining whether a time interval between the second zooming instruction and the first zooming instruction exceeds a preset time threshold, if so, entering step 607, and if not, invalidating the second zooming instruction;

and step 607, restoring the scaled target to the initial size according to the second scaling instruction.

Specifically, the contents of steps 601 to 604 are the same as those of steps 301 to 304 in the first embodiment, and the description of the same contents is omitted in this embodiment.

In an embodiment of the present application, the second zoom instruction includes: touch pressing instruction, touch sliding instruction and shaking instruction or a combination thereof. As will be understood by those skilled in the art, the second operation instruction is an instruction to restore the second picture to the first picture, that is, an inverse operation of the first scaling instruction.

Further, the second scaling instruction may be the same as the first scaling instruction or may be different from the first scaling instruction.

Further, if the second scaling instruction is the same as the first scaling instruction, step 606 is executed, that is: whether the time interval between the second zooming instruction and the first zooming instruction exceeds a preset time threshold value is judged, so that the first zooming instruction is prevented from being mistaken as the second operation instruction when the first zooming instruction is repeated for multiple times.

For example, if the first zoom instruction is set to shake the mobile terminal for the 1 st time, the target is enlarged by 1 time, shake the mobile terminal for the second time, and enlarge the target by 2 times, and the second zoom instruction is set to shake the mobile terminal for the first time, and reduce the target by 1 time, shake the mobile terminal for the second time, and reduce the target by 2 times, the process of zooming and displaying the picture is as follows:

step 1, obtaining a target to be processed from a first picture;

step 2, receiving a first shaking instruction for the target;

step 3, after the first time interval, receiving a second shaking instruction for the target;

step 4, judging whether the first time interval exceeds a preset time threshold, if not, entering step 5, and if so, entering step 6;

step 5, amplifying the target by 2 times, and generating and displaying a picture after amplifying the target by 2 times;

step 6, after the second time interval, receiving a third shaking instruction for the target;

step 7, judging whether the second time interval exceeds a preset time threshold, if not, entering a step 8, and if so, entering a step 9;

step 8, amplifying the target by 3 times, and generating and displaying a picture after amplifying the target by 3 times;

and 9, reducing the picture which is enlarged by 2 times of the target by 1 time. By analogy, this embodiment is not listed one by one.

In this example, when the scheme of the other embodiment is adopted, the process of displaying the picture in a zoomed manner includes the following steps:

step 1, obtaining a target to be processed from a first picture;

step 2, receiving a first shaking instruction for the target;

step 4, judging whether the first time interval exceeds a preset time threshold, if not, entering the step 5, and if so, not processing;

step 6, receiving a third shaking instruction for the target;

step 7, after the second time interval, receiving a fourth shaking instruction for the target;

step 8, judging whether the second time interval exceeds a preset first time threshold, if so, entering step 9, and if not, not processing;

step 9, judging whether the time interval between the third shaking instruction and the first shaking instruction exceeds a preset second time threshold, if so, entering step 10, and if not, not processing;

and step 10, reducing the target in the second picture by 2 times, and reducing the target to the initial size in the first picture.

According to the image zooming display method, the second zooming instruction for the target is received, and when the time interval between the second zooming instruction and the first zooming instruction is judged to exceed the preset time threshold, the zoomed target is restored to the initial size according to the second zooming instruction, so that the image zooming display process is perfected, and the use experience of a user is further improved.

and 804, sorting the different types of targets from high to low.

Specifically, in step 801, the server performs overall training on the recognition targets in advance, and sets different first scores for different targets, for example: the figure score is 50 points, the building score is 40 points, the animal score is 30 points, the scene score is 20 points, and the vegetation score is 10 points. Further, according to the usage habits of most users, the subclass of each target can be scored to obtain a specific first score, for example: in the building category, the score is 48 points if the building is a world famous building, and the score is 43 points if the building is a common building. In other embodiments, the first score may be set according to other criteria, and the application is not limited in this respect.

In step 802, the local database of the mobile terminal sets a second score for different categories of targets according to the usage habits of each user. For example, the second score of the person stored in the album is higher than the second score of the person not stored. Further, if two people appear in the picture at the same time, determining the height of the second fraction according to the area occupied by the people in the picture, wherein the area of the people is the area of the face outline region determined when the face recognition is performed on the picture.

When multiple objects appear in the picture (e.g., a person and a building appear at the same time, or two persons appear), the objects in the picture can be determined according to the height of the sum of the first score and the second score.

Optionally, as shown in fig. 9, acquiring a target to be processed from the displayed first picture includes:

step 901, identifying a first target and at least one second target in a first picture;

a step 902 of sorting the first target and the at least one second target;

step 903, determining the target to be processed in the picture according to the sorting result.

Illustratively, as shown in fig. 10a, a schematic diagram of a first picture displayed on a display screen of a mobile terminal, in the first picture, two character targets are included, namely: character left and character right. Since the target types of the character left and the character right are the same, the first score is the same. Since the area of the picture occupied by the left person is smaller than the area of the picture occupied by the right person, the second score of the left person is smaller than the second score of the right person. Therefore, the sum of the first score and the second score to the right of the character is larger than the left of the character, and the ranking to the right of the character is better than the left of the character, thereby confirming that the right of the character is the target to be processed and enclosing the face to the right of the character with a dotted line. And receiving an instruction of shaking the mobile terminal once by the user. And amplifying the right face in the first picture to generate a second picture as shown in fig. 10b, and displaying the amplified face picture at the central position of the display screen.

Further, in this embodiment, a third zooming instruction and a fourth zooming instruction may be further set to zoom and display other objects in the picture. Specifically, when a first target and at least one second target exist in the first picture and the target to be processed is determined to be the first target through the sorting result, after the first target in the picture is restored to the initial size through the first zooming instruction and the second zooming instruction, the third zooming instruction is received, and corresponding zooming-in or zooming-out operation is performed on the at least one second target according to the third zooming instruction, and zooming processing on the second target is similar to that of the first target, which is not described in detail in this embodiment.

According to the image zooming method, the first target and the at least one second target in the first image are identified, the first target and the at least one second target are sequenced, and the target to be processed in the image is determined according to the sequencing result, so that the situation that multiple targets exist in the first image is refined, the mobile terminal is more intelligent, and better use experience is brought to a user.

Fourth embodiment

As shown in fig. 11, a mobile terminal according to another embodiment of the present application includes a processor 1110 and a memory 1120;

acquiring a target to be processed from a displayed first picture;

receiving a first zoom instruction for the target;

and displaying the second picture.

Specifically, when the current interface is monitored to display a picture, the target to be processed is triggered to be obtained from the displayed first picture. In this embodiment, the picture may be a picture or a photo in an album of the mobile terminal, may also be a picture or a photo currently taken by the camera application, and may also be a picture or a photo opened by another application. For example, a photo in a WeChat friend circle that the user is browsing.

Further, when the second picture is displayed, the second picture can be automatically moved to the center of the screen for display.

step 1, monitoring that a current interface displays pictures in an album;

step 3, receiving a shaking instruction;

and 5, displaying the amplified human face picture.

Optionally, the processor 1110 is further configured to execute a picture scaling display program stored in the memory 1120, so as to implement the following steps:

receiving an editing instruction of the second picture;

receiving a second zoom instruction for the target;

specifically, the second zoom instruction includes: touch pressing instruction, touch sliding instruction and shaking instruction or a combination thereof. As will be understood by those skilled in the art, the second operation instruction is an instruction to restore the second picture to the first picture, that is, an inverse operation of the first scaling instruction.

For example, if the first zoom instruction is set to shake the mobile terminal for the first time, the target is enlarged by 1 time, shake the mobile terminal for the second time, and enlarge the target by 2 times, and the second zoom instruction is set to shake the mobile terminal for the first time, and reduce the target by 1 time, shake the mobile terminal for the second time, and reduce the target by 2 times, the process of zooming and displaying the picture is as follows:

step 1, obtaining a target to be processed from a first picture;

step 2, receiving a first shaking instruction for the target;

step 1, obtaining a target to be processed from a first picture;

step 2, receiving a first shaking instruction for the target;

step 6, receiving a third shaking instruction for the target;
