Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of a method for scaling an image according to the present invention. The execution subject of this embodiment is a user device, which may be implemented by any software and/or hardware. The user equipment may specifically be a mobile phone, a video camera, a computer, or other user equipment capable of performing picture processing, and may also be an execution subject of this embodiment. For the specific implementation manner of the user equipment in this embodiment, details of this embodiment are not repeated here. As shown in fig. 1, the method of this embodiment may include:
step 101, obtaining an instruction for carrying out zooming operation on a picture to be zoomed;
102, acquiring attribute information of the picture to be zoomed, and determining a zooming point of the picture to be zoomed according to the attribute information of the picture to be zoomed;
and 103, zooming the picture to be zoomed by taking the zooming point as a zooming center.
In a specific implementation process, a user may perform scaling processing on a picture stored in a user device, and those skilled in the art can understand that the picture may be a picture downloaded by the user from the internet or a picture taken by the user device. The source of the picture is not limited in this embodiment.
Specifically, in step 101, the user equipment performs scaling processing on the picture only after acquiring an instruction that the user equipment performs scaling operation on the picture to be scaled.
In a specific implementation process, the user equipment obtains an instruction for performing scaling operation on a picture to be scaled, which is triggered by a user, and includes the following possible implementation manners.
According to a possible implementation manner, an instruction for zooming the picture to be zoomed, which is triggered by a user by touching any position of the picture to be zoomed, is obtained.
Specifically, when the user equipment includes a touch screen, and the user needs to perform a zoom operation on the picture to be zoomed, after the user opens the picture to be zoomed, the user may trigger an instruction for performing the zoom operation on the picture to be zoomed by touching any position of the picture to be zoomed.
In a specific implementation process, the touch screen is provided with two capacitive sensors, namely a mutual capacitance and a self-capacitance. And the mutual capacitance is used for realizing multi-point touch detection. Self-capacitance can produce a stronger signal than mutual capacitance to detect more distant finger sensing, but multi-point detection is not possible due to an effect called "ghosting". The mutual capacitance is used for completing normal touch sensing, including multi-point touch. Therefore, according to different functions of the sensor capacitance on the touch screen, the user touches the picture to be zoomed displayed on the touch screen, wherein the picture to be zoomed includes two conditions of touch control and floating touch control. For touch control, multi-touch detection by mutual capacitance is mainly used. For hover touch, a finger hovering above is detected primarily by self-capacitance.
Those skilled in the art can understand that the above description is only an illustrative example of how to implement the contact touch and the floating touch, and the implementation manner of implementing the contact touch and the floating touch is not particularly limited in this embodiment.
In another possible implementation manner, an instruction for performing a zoom operation on the picture to be zoomed, which is triggered by a voice of a user, is obtained.
Specifically, when the user equipment includes a microphone, and the user needs to perform a zoom operation on the picture to be zoomed, after the user opens the picture to be zoomed, the user may trigger an instruction to zoom the picture to be zoomed by voice, for example, "picture zoom" or the like. When a sound sensitive sensor on user equipment senses voice of a user or an earphone on the user equipment receives a signal of 'picture zooming', the semantic meaning of the voice is identified, and if the semantic meaning is picture zooming, an instruction triggered by the user to zoom the picture to be zoomed is obtained.
In another possible implementation manner, an instruction for performing a zoom operation on the picture to be zoomed, which is triggered by pressing a preset key by a user, is obtained.
Specifically, when a user needs to perform zooming operation on a picture to be zoomed, the user presses a preset key, and when a pressure sensor on user equipment senses that the user presses the preset key, an instruction triggered by the user to zoom the picture to be zoomed is acquired. Those skilled in the art can understand that, in this embodiment, the user equipment may include a touch screen, may not include the touch screen, may include a microphone, or may not include the microphone, as long as the user equipment includes a function key, and any function key set on the user equipment may be used as the preset key.
Those skilled in the art can understand that the present embodiment is not limited to the foregoing possible implementation manners, and may also be other possible implementation manners, for example, the user equipment may further obtain, through a photosensitive sensor, a gas sensor, a temperature-sensitive sensor, and the like, an instruction, which is triggered by the user and corresponds to the sensor, for performing a zoom operation on the to-be-zoomed image.
In step 102, the user equipment acquires attribute information of a picture to be zoomed. The attribute information of the picture to be zoomed refers to the attribute and information of the picture to be zoomed. For example, the focus position when photographing is focused, the position of the human face in the picture to be zoomed, the size of the picture, and the like can be used.
And determining a zooming point of the picture to be zoomed according to the attribute information of the picture to be zoomed. For example, the focus position at the time of focusing of photographing of a picture to be zoomed is taken as a zoom point.
In step 103, the user equipment performs scaling processing on the picture to be scaled by using the scaling point determined in step 102 as a scaling center of the picture to be scaled.
According to the image zooming method provided by the embodiment of the invention, the instruction for zooming the image to be zoomed, which is triggered by a user, is obtained; acquiring attribute information of the picture to be zoomed, and determining a zooming point of the picture to be zoomed according to the attribute information of the picture to be zoomed; and zooming the picture to be zoomed by taking the zooming point as a zooming center, wherein the user does not need to determine the zooming center, but the user equipment determines the zooming center which is interested by the user, and then the user equipment performs zooming, so that the operation of the user in the picture zooming process is simplified, and the operation efficiency is improved.
The following describes in detail the image scaling method according to the embodiment of the present invention by using several specific embodiments, and specifically refer to fig. 2 to 4.
Fig. 2 is a flowchart of a second embodiment of a method for scaling an image according to the present invention. As shown in fig. 2, the method for scaling an image provided by this embodiment includes:
step 201, when the picture to be zoomed is obtained by photographing, recording the focus position of the picture to be zoomed when the picture is photographed and focused, and taking the focus position of the picture to be zoomed when the picture is photographed and focused as the attribute information of the picture to be zoomed;
step 202, obtaining an instruction for performing zooming operation on the picture to be zoomed;
step 203, acquiring a focal position of the picture to be zoomed when the picture is photographed and focused, and taking the focal position of the picture to be zoomed when the picture is photographed and focused as a zooming point of the picture to be zoomed;
and step 204, taking the zooming point as a zooming center, and zooming the picture to be zoomed.
In this embodiment, step 202 is similar to step 101, and step 204 is similar to step 103, which are not described herein again.
In this embodiment, in step 201, when the picture to be zoomed is obtained by taking a picture, and the user equipment takes a picture to obtain the picture to be zoomed, the focus position when the picture is focused is recorded, and the focus position is used as the attribute information of the picture to be zoomed. Those skilled in the art will understand that the attribute information of the picture to be zoomed includes information of various pictures to be zoomed, and here, the focus position is only used as one attribute information of the picture to be zoomed.
In step 203, the user equipment acquires the attribute information, acquires the focal position of the photographing focus from the attribute information, and takes the focal position of the photographing focus as the zoom point of the picture to be zoomed.
Those skilled in the art can understand that, in the embodiment, the to-be-zoomed picture obtained by photographing may be stored in the user equipment together with the to-be-zoomed picture by taking the focus position as the attribute information of the to-be-zoomed picture in advance. When the user needs to zoom the picture to be zoomed, the attribute information can be directly used without being acquired again, i.e. the process is directly started from step 202.
According to the image zooming method provided by the embodiment of the invention, when the image to be zoomed is obtained by photographing, the focus position during photographing focusing is recorded, and the focus position during photographing focusing is used as the attribute information of the image to be zoomed; acquiring an instruction for carrying out zooming operation on a picture to be zoomed, which is triggered by a user; acquiring the focal position of the photographing focus, and taking the focal position of the photographing focus as a zooming point of the picture to be zoomed; and zooming the picture to be zoomed by taking the zooming point as a zooming center. Because the picture to be zoomed obtained by photographing only has one focus, when the user zooms the picture, the picture to be zoomed is zoomed by taking the focus position as a zooming point and taking the zooming point as a zooming center, so that the focus of the user is better focused, and the operation of the user is simplified.
Fig. 3 is a flowchart of a third embodiment of a method for scaling an image according to the present invention. As shown in fig. 3, the method for scaling an image according to this embodiment includes:
step 301, when it is determined that the picture to be zoomed includes a face, performing face recognition on the picture to be zoomed, acquiring the position of the face in the picture to be zoomed, and using the position of the face in the picture to be zoomed as attribute information of the picture to be zoomed;
step 302, obtaining an instruction for performing zooming operation on the picture to be zoomed;
step 303, obtaining the position of the face in the picture to be zoomed, and taking the position of the face in the picture to be zoomed as a zooming point of the picture to be zoomed;
and step 304, taking the zooming point as a zooming center, and zooming the picture to be zoomed.
In this embodiment, step 302 is similar to step 101, and step 304 is similar to step 103, which are not described herein again.
The picture to be zoomed in the present embodiment may be a photographic work of a subject person or a picture of a subject person. The following embodiment describes a specific implementation process in detail.
In step 301, a picture to be zoomed is identified through a face identification technology, whether the picture to be zoomed includes a face is determined, if the picture to be zoomed includes the face, the position of the face in the picture to be zoomed is obtained, and the position of the face in the picture to be zoomed is used as attribute information of the picture to be zoomed. The face recognition method related to the face recognition technology in this embodiment may specifically be a face recognition method of geometric features, a face recognition method of a neural network, a face recognition method of elastic image matching, a face recognition method of a support vector machine, or the like. For a specific face recognition method, details of this embodiment are not repeated here.
Further, step 301 may be specifically divided into the following two possible implementation manners according to the number of faces in the picture to be zoomed.
In a first possible implementation manner, it is determined that the picture to be zoomed includes a face, and the face recognition is performed on the picture to be zoomed to obtain the number of faces in the picture to be zoomed; and when the number of the human faces is 1, acquiring the position of the human face in the picture to be zoomed, and taking the position of the human face in the picture to be zoomed as the attribute information of the picture to be zoomed.
Specifically, when the number of faces is 1, as shown in fig. 4, fig. 4 is a schematic diagram of a first embodiment of the face recognition result of the present invention, and in fig. 4, the position enclosed by the black line frame is the recognition result of the face. In fig. 4, one face is included. The center position of the black line frame is the position of the face in the picture to be zoomed, and then the position of the face in the picture to be zoomed is used as the attribute information of the picture to be zoomed.
In a second possible implementation manner, when the number of faces is multiple, the two possible situations are divided into two, specifically as follows:
one possible scenario is: determining that the picture to be zoomed comprises a face, and carrying out face recognition on the picture to be zoomed to obtain the number of the faces in the picture to be zoomed; when the number of the faces is more than 1, determining the face corresponding to the largest area in the faces, acquiring the position of the face corresponding to the largest area in the picture to be zoomed, and then taking the position of the face in the picture to be zoomed as the attribute information of the picture to be zoomed.
Specifically, when the number of faces is multiple, as shown in fig. 5, fig. 5 is a schematic diagram of a second embodiment of the face recognition result of the present invention, and in fig. 5, the position enclosed by the black line frame is the recognition result of the face. In fig. 5, 3 faces are included. At this time, the size of the area of the 3 faces is obtained, the area of the face located at the top is the largest, at this time, the position of the face in the picture to be zoomed is obtained, and then the position of the face in the picture to be zoomed is used as the attribute information of the picture to be zoomed.
Another possible scenario is: determining that the picture to be zoomed comprises a face, and carrying out face recognition on the picture to be zoomed to obtain the number of the faces in the picture to be zoomed; and when the number of the human faces is more than 1, acquiring the position of the human face in a preset area in the picture to be zoomed in and out.
Specifically, the preset region in this embodiment may be a preset central region, a preset upper region, a preset lower region, a preset left region, a preset right region, and the like, and the specific region represented by the preset region is not particularly limited herein. Taking a specific example as an example, when the number of faces is multiple, as shown in fig. 6, fig. 6 is a schematic diagram of a third embodiment of the face recognition result of the present invention, and in fig. 6, the position enclosed by the black line frame is the recognition result of the face. In fig. 6, a total of 5 faces are identified. Counting from left to right, if the third face is located in the preset central area, the position of the third face in the picture to be zoomed is obtained, and then the position of the face in the picture to be zoomed is used as the attribute information of the picture to be zoomed.
Those skilled in the art can understand that the attribute information of the picture to be zoomed includes information of various pictures to be zoomed, and in the above embodiments, only the position of the face in the picture to be zoomed is taken as one attribute information of the picture to be zoomed.
Further, in the specific implementation process, step 301 and step 302 have no strict timing relationship. The position of the face in the picture to be zoomed can be used as the attribute information of the picture to be zoomed in advance, and the position of the face in the picture to be zoomed can be obtained and used as the attribute information after the instruction for zooming the picture to be zoomed, which is triggered by the user, is obtained.
In step 303, the user equipment acquires the attribute information of the picture to be zoomed, acquires the position of the face in the picture to be zoomed from the attribute information of the picture to be zoomed, and takes the position of the face in the picture to be zoomed as a zooming point of the picture to be zoomed.
The embodiment of the invention carries out face recognition on the picture to be zoomed to obtain the position of the face in the picture to be zoomed, and the position of the face in the picture to be zoomed is taken as the attribute information of the picture to be zoomed; acquiring an instruction for carrying out zooming operation on a picture to be zoomed, which is triggered by a user; acquiring attribute information of the picture to be zoomed, acquiring the position of the face in the picture to be zoomed from the attribute information of the picture to be zoomed, and taking the position of the face in the picture to be zoomed as a zooming point of the picture to be zoomed; and zooming the picture to be zoomed by taking the zooming point as a zooming center. When the user zooms the photo, the face position is used as a zooming point, the zooming point is used as a zooming center, and the picture to be zoomed is zoomed, so that the focus of the user is better focused, and the operation of the user is simplified.
FIG. 7 is a flowchart illustrating a fourth method for scaling an image according to the present invention. As shown in fig. 7, the method for scaling an image according to this embodiment includes:
step 701, obtaining a zoom area of a standard picture and a picture type of the standard picture determined by a user, establishing a corresponding relation between the picture type and the zoom area, and storing the corresponding relation into the picture information table;
step 702, acquiring the picture type of the picture to be zoomed, determining a zooming area corresponding to the picture type according to a picture information table, and taking the zooming area as attribute information of the picture to be zoomed;
step 703, obtaining an instruction for performing a zoom operation on the picture to be zoomed;
step 704, obtaining the zooming area, determining a central point of the zooming area, and taking the central point of the zooming area as a zooming point of the picture to be zoomed;
step 705, taking the zoom point as a zoom center, and performing zoom processing on the picture to be zoomed.
In this embodiment, step 703 is similar to step 101, and step 705 is similar to step 103, which are not described herein again.
In step 701, a picture information table is first established, and those skilled in the art can understand that the picture information table may be established by the user equipment in this embodiment, or may be pre-established by other user equipment and pre-stored in the user equipment in this embodiment. The picture information table mainly has the function of determining the zooming area according to the historical behavior rule of the user.
In a specific implementation process, user equipment acquires a zoom region of a standard picture determined by a user and a picture type of the standard picture, establishes a corresponding relationship between the picture type and the zoom region, and stores the corresponding relationship into a picture information table, namely the picture information table is used for storing the corresponding relationship between the picture type and the zoom region.
Wherein the standard picture is a picture of which the user equipment has determined the zoom area. The zooming area of the picture to be zoomed determined by the user in the past can be collected and used as the zooming area of the standard picture. Or, providing a plurality of standard images for a plurality of users, determining the zooming area of each standard image by the plurality of users, then collecting information, integrating, establishing the corresponding relation between the picture type and the zooming area, and storing the corresponding relation into the picture information table. The picture type can be various landscape pictures, various human pictures or various animal pictures, etc. For example, when the picture type is a landscape picture, since the landscape picture involves many scenes, the zoom area may be a central area of the landscape picture or an area where a main scene of the landscape picture is located; when the picture type is a figure picture, the zooming area can be the middle upper area of the picture because the human face is positioned at the middle upper part of the picture; when the picture type is an animal picture, the corresponding zoom areas of different animals are different, when the animal is a bird, the zoom area can be the middle upper area of the picture, and when the animal is a land animal, the zoom area can be the middle lower area of the picture. The embodiment is not particularly limited herein with respect to the correspondence between the picture type and the zoom area.
In step 702, a picture type of the picture to be zoomed is obtained, a zooming area corresponding to the picture type is determined in the picture information table, and the zooming area is used as attribute information of the picture to be zoomed.
Specifically, the corresponding relationship between the picture type of the standard picture and the zooming area is stored in the picture information table, when the zooming point of the picture to be zoomed is obtained, the picture type of the picture to be zoomed is obtained first, then the picture type of the picture to be zoomed is matched with the picture type of the standard picture in the picture information table, and when the picture type of the picture to be zoomed is consistent with the picture type of the standard picture in the picture information table, the zooming area corresponding to the picture type of the standard picture in the picture information table is used as the zooming area of the picture to be zoomed and is used as the attribute information of the picture to be zoomed.
For example, after the picture to be zoomed is acquired, the picture type of the picture to be zoomed is determined to be a landscape picture through an image recognition technology, the picture type of the picture to be zoomed is matched with the picture type of the standard picture in the picture information table, when the picture type of the standard picture is the landscape picture, the matching is successful, a zooming area corresponding to the standard picture in the picture information table is used as a zooming area of the picture to be zoomed, and the zooming area is used as attribute information of the picture to be zoomed.
For another example, after the picture to be zoomed is obtained, the picture type of the picture to be zoomed is determined to be a bird picture in an animal picture through an image recognition technology, the bird picture is matched with the picture type of the standard picture in the picture information table, when the picture type of the standard picture is the bird picture, the matching is successful, the zooming area corresponding to the standard picture in the picture information table is used as the zooming area of the picture to be zoomed, and the zooming area is used as the attribute information of the picture to be zoomed.
For other specific embodiments, the description of the present embodiment is omitted here. As will be understood by those skilled in the art, the attribute information of the picture to be zoomed includes information of various pictures to be zoomed, and in the above embodiments, only the zoom area is used as one attribute information of the picture to be zoomed.
Further, in the specific implementation process, the step 702 and the step 703 have no strict timing relationship. The zooming region can be used as attribute information of the picture to be zoomed in advance, or after an instruction triggered by a user for zooming the picture to be zoomed is obtained, the picture type of the picture to be zoomed is obtained, the zooming region corresponding to the picture type is determined in the picture information table, and the zooming region is used as the attribute information of the picture to be zoomed.
In step 704, the user equipment obtains attribute information of the picture to be zoomed, obtains a zooming region from the attribute information of the picture to be zoomed, determines a center point of the zooming region, and takes the center point of the zooming region as a zooming point of the picture to be zoomed.
According to the image zooming method provided by the embodiment of the invention, the zooming area of the standard image determined by a user and the image type of the standard image are obtained, the corresponding relation between the image type and the zooming area is established, and the corresponding relation is stored in the image information table; acquiring the picture type of the picture to be zoomed, determining a zooming area corresponding to the picture type in a picture information table, and taking the zooming area as attribute information of the picture to be zoomed; acquiring an instruction for carrying out zooming operation on a picture to be zoomed, which is triggered by a user; acquiring attribute information of the picture to be zoomed, acquiring the zooming area from the attribute information of the picture to be zoomed, determining a central point of the zooming area, and taking the central point of the zooming area as a zooming point of the picture to be zoomed; and zooming the picture to be zoomed by taking the zooming point as a zooming center. When the user zooms the photo, the zooming point is determined according to the historical behavior activity of the user, and the picture to be zoomed is zoomed by taking the zooming point as a zooming center, so that the focus of the user is better focused, and the operation of the user is simplified.
