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 obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

图 1为本发明图片缩放方法实施例一的流程图。本实施例的执行主体为用户设备，该用户设备可由任意的软件和 /或硬件实现。该用户设备具体可以为手机、摄像机、照相机、电脑等，其它可以进行图片处理的用户设备，也可以作为本实施例的执行主体。对于本实施例的用户设备的具体实现方式，本实施例此处不再赘述。如图 1所示，本实施例的方法可以包括： FIG. 1 is a flowchart of Embodiment 1 of a picture zooming method according to the present invention. The execution subject of this embodiment is a user equipment, and the user equipment can be implemented by any software and/or hardware. The user equipment can be specifically For a mobile phone, a video camera, a camera, a computer, etc., other user equipments that can perform picture processing can also be used as an execution subject of the present embodiment. The specific implementation manner of the user equipment in this embodiment is not described herein again. As shown in FIG. 1, the method in this embodiment may include:

步骤 101、获取对待缩放图片进行缩放操作的指令； Step 101: Acquire an instruction for performing a scaling operation on the zoomed image;

步骤 102、获取所述待缩放图片的属性信息，根据所述待缩放图片的属性信息，确定所述待缩放图片的缩放点； Step 102: Obtain attribute information of the to-be-scaled picture, and determine a zoom point of the to-be-scaled picture according to the attribute information of the to-be-scaled picture;

步骤 103、以所述缩放点为缩放中心，对所述待缩放图片进行缩放处理。在具体实现过程中，用户可对用户设备上存储的图片进行缩放处理，本领域技术人员可以理解，该图片可以为用户从网上下载的图片，也可以为用户通过用户设备拍照获取的。对于图片的来源，本实施例此处不做具体限制。 Step 103: Perform scaling processing on the to-be-scaled picture by using the zoom point as a zoom center. In a specific implementation process, the user may perform a scaling process on the image stored on the user equipment. A person skilled in the art may understand that the picture may be a picture downloaded by the user from the Internet, or may be obtained by the user taking a picture through the user equipment. For the source of the picture, this embodiment does not specifically limit it.

具体地，在步骤 101中，用户设备只有在获取到用户设备对待缩放图片进行缩放操作的指令之后，才对图片进行缩放处理。 Specifically, in step 101, the user equipment performs the scaling process only after acquiring the instruction that the user equipment performs the scaling operation on the picture to be scaled.

在具体实现过程中，用户设备获取用户触发的对待缩放图片进行缩放操作的指令，包括以下可能的实现方式。 In a specific implementation process, the user equipment acquires a user-triggered instruction for performing a scaling operation on the image to be scaled, including the following possible implementation manners.

一种可能的实现方式，获取用户通过触碰所述待缩放图片的任意位置触发的对所述待所缩放图片进行缩放操作的指令。 In one possible implementation, an instruction for zooming the picture to be zoomed by the user by touching any position of the picture to be zoomed is obtained.

具体地，当用户设备包括触摸屏时，用户需要对待缩放图片进行缩放操作时，用户在打开待缩放图片之后，用户可通过触碰待缩放图片的任意位置触发对待缩放图片进行缩放操作的指令。 Specifically, when the user equipment needs to perform a zoom operation on the zoomed picture when the user equipment includes the touch screen, after the user opens the image to be zoomed, the user can trigger an instruction to perform the zoom operation on the zoomed picture by touching any position of the picture to be zoomed.

在具体实现过程中，触摸屏上有两种电容式传感器，互电容和自电容。互电容，用于实现多点触摸检测。自电容能够产生比互电容强大的信号，检测更远的手指感应，但由于一种被成为"鬼影 (ghosting)"的效应，无法进行多点检测。互电容用于完成正常的触碰感应，包括多点触控。因此，根据触摸屏上传感器电容的不同作用，用户触碰触摸屏上显示的待缩放图片包括接触触控和悬浮触控两种情况。对于接触触控，主要通过互电容的多点触摸检测实现。对于悬浮触控，主要通过自电容检测悬停在上方的手指。 In the specific implementation process, there are two kinds of capacitive sensors, mutual capacitance and self capacitance on the touch screen. Mutual capacitance for multi-touch detection. Self-capacitance can produce a stronger signal than mutual capacitance, detecting farther finger sensing, but due to a "ghosting" effect, multi-point detection is not possible. Mutual capacitance is used to complete normal touch sensing, including multi-touch. Therefore, according to the different functions of the sensor capacitance on the touch screen, the user can touch the image to be zoomed displayed on the touch screen, including contact touch and hover touch. For touch touch, it is mainly realized by multi-touch detection of mutual capacitance. For hovering touch, the finger that is hovering above is mainly detected by self-capacitance.

本领域技术人员可以理解，上述仅是示意性的说明如何实现接触触控和悬浮触控，本实施例对实现接触触控和悬浮触控的实现方式，不做特别限制。 It is to be understood by those skilled in the art that the above description is merely illustrative of how to implement touch and hovering touch. The implementation of the touch and hover touch is not particularly limited in this embodiment.

另一种可能的实现方式，获取用户通过语音触发的对所述待所缩放图片进行缩放操作的指令。具体地，当用户设备包括话筒时，用户需要对待缩放图片进行缩放操作时，用户在打开待缩放图片之后，可以通过语音，例如"图片缩放"等触发对待缩放图片进行缩放的指令。当用户设备上的声敏传感器感知到用户的语音或用户设备上的听筒接收到该"图片缩放"的信号时，对该语音的语义进行识别，若语义为图片缩放，则获取到用户触发的对待缩放图片进行缩放的指令。 Another possible implementation manner is to obtain an instruction that the user triggers a zoom operation on the to-be-scaled picture by voice. Specifically, when the user equipment needs to perform a zoom operation on the zoomed picture when the user equipment includes the microphone, after the user opens the picture to be zoomed, the user may trigger an instruction to zoom the picture by using a voice, such as “picture zoom”. When the acoustic sensor on the user device senses that the user's voice or the earpiece on the user equipment receives the signal of the "picture zoom", the semantics of the voice is recognized, and if the semantic is a picture zoom, the user triggers An instruction to scale a scaled picture.

再一种可能的实现方式，获取用户通过按压预设按键触发的对所述待所缩放图片进行缩放操作的指令。 In another possible implementation, an instruction for zooming the zoomed-out picture triggered by the user by pressing a preset button is obtained.

具体地，用户需要对待缩放图片进行缩放操作时，用户按压预设按键，当用户设备设备上的压力传感器感知到用户按压预设按键时，获取到用户触发的对待缩放图片进行缩放的指令。本领域技术人员可以理解，在本实施例中，用户设备可以包括触摸屏，也可以不包括触摸屏，可以包括话筒也可以不包括话筒，只要该用户设备包括功能按键即可，可以将用户设备上设置的任意功能键作为预设按键。 Specifically, when the user needs to perform a zoom operation on the zoomed image, the user presses the preset button, and when the pressure sensor on the user equipment device senses that the user presses the preset button, the user triggers an instruction to zoom the image to be zoomed. It can be understood by those skilled in the art that in this embodiment, the user equipment may include a touch screen or may not include a touch screen, and may or may not include a microphone. As long as the user equipment includes a function button, the user equipment may be set. Any function key is used as a preset button.

本领域技术人员可以理解，本实施例并不限于上述可能的实现方式，还可以为其它可能的实现方式，例如，用户设备还可通过光敏传感器、气敏传感器、温敏传感器等，获取用户触发的与传感器对应的对待所缩放图片进行缩放操作的指令。 A person skilled in the art can understand that the embodiment is not limited to the foregoing possible implementation manners, and may be other possible implementation manners. For example, the user equipment may also obtain a user trigger by using a photo sensor, a gas sensor, a temperature sensor, or the like. An instruction corresponding to the sensor to perform a scaling operation on the scaled picture.

在步骤 102中，用户设备获取待缩放图片的属性信息。其中，待缩放图片的属性信息是指待缩放图片本身具有的属性和信息。例如，可以为拍照聚焦时的焦点位置、人脸在待缩放图片的位置、图片的大小等。 In step 102, the user equipment acquires attribute information of the picture to be scaled. The attribute information of the image to be zoomed refers to the attribute and information of the picture to be scaled. For example, it may be a focus position when a photograph is focused, a position of a face to be scaled, a size of a picture, and the like.

再根据待缩放图片的属性信息，确定待缩放图片的缩放点。例如，将待缩放图片的拍照聚焦时的焦点位置作为缩放点。 Then, according to the attribute information of the picture to be zoomed, the zoom point of the picture to be zoomed is determined. For example, the focus position when the photograph of the picture to be zoomed is focused is used as the zoom point.

在步骤 103中，用户设备以步骤 102中确定的缩放点，作为待缩放图片的缩放中心，对待缩放图片进行缩放处理。 In step 103, the user equipment performs a scaling process on the zoomed picture as the zoom center of the picture to be zoomed with the zoom point determined in step 102.

本发明实施例提供的图片缩放方法，通过获取用户触发的对待缩放图片进行缩放操作的指令；获取所述待缩放图片的属性信息，根据所述待缩放图片的属性信息，确定所述待缩放图片的缩放点；以所述缩放点为缩放中心，对所述待缩放图片进行缩放处理，用户不需要确定缩放中心，而是由用户设备确定用户感兴趣的缩放中心，进而用户设备进行缩放处理，简化了用户在图片缩放处理过程的操作，提高了操控效率。下面采用几个具体的实施例，对本发明实施例提供的图片缩放方法进行详细说明，具体可参照图 2至图 4。 The image zooming method provided by the embodiment of the present invention obtains an instruction for performing a zoom operation by a user-triggered image to be scaled; acquiring attribute information of the to-be-scaled image, and determining the to-be-scaled image according to the attribute information of the to-be-scaled picture Zooming point; using the zoom point as a zoom center, performing scaling processing on the to-be-scaled picture, the user does not need to determine the zoom center, but the user equipment determines the zoom center that the user is interested in, and then the user equipment performs scaling processing. It simplifies the user's operation in the image scaling process and improves the control efficiency. The image scaling method provided by the embodiment of the present invention is described in detail below with reference to FIG. 2 to FIG. 4 .

在本实施例中，步骤 201中，当该待缩放图片为通过拍照方式获取时，用户设备在拍照获取待缩放图片时，记录拍照聚焦时的焦点位置，并将焦点位置作为待缩放图片的属性信息。本领域技术人员可以理解，待缩放图片的属性信息包括各种待缩放图片的信息，此处，只是将焦点位置作为待缩放图片的一种属性信息。 In this embodiment, in step 201, when the picture to be zoomed is acquired by the photographing mode, when the user equipment takes a picture to obtain a picture to be zoomed, the focus position of the photo focus is recorded, and the focus position is used as an attribute of the picture to be zoomed. information. Those skilled in the art can understand that the attribute information of the picture to be scaled includes information of various pictures to be scaled, and here, only the focus position is regarded as an attribute information of the picture to be zoomed.

在步骤 203中，用户设备获取属性信息，从属性信息中获取拍照聚焦时的焦点位置，将拍照聚焦时的焦点位置作为所述待缩放图片的缩放点。 In step 203, the user equipment acquires the attribute information, obtains the focus position when the photograph is focused from the attribute information, and uses the focus position when the photograph is focused as the zoom point of the to-be-scaled picture.

本领域技术人员可以理解，在本实施例中，通过拍照获取的待缩放图片，都可以预先将焦点位置作为待缩放图片的属性信息，与待缩放照片一起保存在用户设备中。在用户需要对待缩放图片进行缩放处理时，可直接使用该属性信息，不需要再次获取，即直接从步骤 202开始执行。 It can be understood by those skilled in the art that in this embodiment, the image to be zoomed by taking a picture can be used as the attribute information of the picture to be zoomed in advance, and saved in the user equipment together with the picture to be zoomed. When the user needs to perform scaling processing on the zoomed picture, the attribute information can be directly used, and does not need to be acquired again, that is, directly from step 202.

本发明实施例提供的图片缩放方法，通过拍照获取所述待缩放图片时，记录拍照聚焦时的焦点位置，将所述拍照聚焦时的焦点位置作为所述待缩放图片的属性信息；获取用户触发的对待缩放图片进行缩放操作的指令；获取所述拍照聚焦时的焦点位置，将所述拍照聚焦时的焦点位置作为所述待缩放图片的缩放点；以所述缩放点为缩放中心，对所述待缩放图片进行缩放处理。由于拍照获取的待缩放图片只会有一个焦点，所以当用户在缩放照片时，以焦点位置作为缩放点，以该缩放点作为缩放中心，对待缩放图片进行缩放，不仅更好的聚焦用户的关注点，还简化了用户的操作。 In the image zooming method provided by the embodiment of the present invention, when the image to be zoomed is acquired by photographing, the focus position when the photographing is focused is recorded, and the focus position when the photographing is focused is used as the attribute information of the to-be-scaled image; An instruction to perform a zoom operation on the zoomed image; obtaining a focus position when the photograph is focused, and using a focus position when the photograph is focused as a zoom point of the to-be-scaled image; using the zoom point as a zoom center, The zoomed image is described for scaling processing.

In FIG. 4, the position framed by the black wire frame is the face recognition. result. In Figure 4, a face is included. The center position of the black wire frame is the position of the face to be zoomed 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.

第二种可能的实现方式，当人脸个数为多个时，又分为两种可能的情况，具体如下： The second possible implementation method, when there are multiple faces, is divided into two possible situations, as follows:

具体地，当人脸个数为多个时，如图 5所示，图 5为本发明人脸识别结果实施例二的示意图，在图 5中，黑色线框所框住的位置为人脸的识别结果。在图 5中，包括 3个人脸。此时，获取 3个人脸的面积大小，则位于最上方的人脸的面积最大，此时，获取该人脸在待缩放图片的位置，然后，将该人脸在待缩放图片的位置作为待缩放图片的属性信息。 Specifically, when the number of faces is plural, as shown in FIG. 5, FIG. 5 is a schematic diagram of Embodiment 2 of the face recognition result of the present invention. In FIG. 5, the position of the black wire frame is a face. Identify the results. In Figure 5, it includes 3 faces. At this time, the size of the face of the three faces is obtained, and the area of the face at the top is the largest. At this time, the face of the face is obtained at the position of the image to be zoomed, and then the face is taken as the position of the image to be zoomed. Scale the attribute information of the image.

另一种可能的情况为：确定待缩放图片中包括人脸，对待缩放图片进行人脸识别，获取待缩放图片中的人脸个数；在所述人脸个数大于 1个时，获取所述待缩放图片中位于预设区域的人脸在所述待缩放图片的位置。 Another possible situation is: determining that a face to be zoomed includes a face, performing face recognition on the zoomed image, and obtaining a number of faces in the image to be zoomed; when the number of the faces is greater than one, obtaining the location The face of the zoomed picture located in the preset area is in the position of the picture to be zoomed.

具体地，本实施例中的预设区域可以为预设中心区域，预设上部区域，预设下部区域，预设左部区域，预设右部区域等，对于预设区域所代表的具体区域，本实施例此处不作特别限制。以一个具体的例子为例，当人脸个数为多个时，如图 6所示，图 6为本发明人脸识别结果实施例三的示意图，在图 6中，黑色线框所框住的位置为人脸的识别结果。在图 6中，共识别出 5 个人脸。从左至右数，第三个人脸位于预设中心区域，则获取第三个人脸在待缩放图片的位置，然后，将该人脸在待缩放图片的位置作为待缩放图片的属性信息。 Specifically, the preset area in this embodiment may be a preset central area, a preset upper area, a preset lower area, a preset left area, a preset right area, and the like, and a specific area represented by the preset area. This embodiment is not particularly limited herein. Taking a specific example as an example, when the number of faces is plural, as shown in FIG. 6, FIG. 6 is a schematic diagram of Embodiment 3 of the face recognition result of the present invention. In FIG. 6, the black wire frame is framed. The position is the recognition result of the face. In Figure 6, a total of 5 faces were identified. From left to right, the third person's face is located in the preset center area, and the position of the third person's face in the picture to be zoomed is obtained, and then the position of the face in the picture to be zoomed is taken as the attribute information of the picture to be zoomed.

本领域技术人员可以理解，待缩放图片的属性信息包括各种待缩放图片的信息，在上述各实施例中，只是将人脸在待缩放图片的位置作为待缩放图片的一种属性信息。 It can be understood by those skilled in the art that the attribute information of the picture to be scaled includes information of various pictures to be scaled. In the above embodiments, only the position of the face to be zoomed is used as an attribute information of the picture to be zoomed.

进一步地，在具体实现过程中，步骤 301与步骤 302没有严格的时序关系。可以预先将人脸在待缩放图片的位置作为待缩放图片的属性信息，也可以在获取到用户触发的对待缩放图片进行缩放操作的指令之后，获取人脸在待缩放图片的位置，并作为属性信息。 Further, in the specific implementation process, steps 301 and 302 have no strict timing. Department. The position of the face to be zoomed may be used as the attribute information of the picture to be zoomed in advance, or after the instruction of the zoom operation of the picture to be zoomed by the user is acquired, the position of the face to be zoomed is obtained, and is used as an attribute. information.

在步骤 303中，用户设备获取所述待缩放图片的属性信息，从所述待缩放图片的属性信息中，获取人脸在所述待缩放图片的位置，将所述人脸在所述待缩放图片的位置作为所述待缩放图片的缩放点。 In step 303, the user equipment acquires the attribute information of the to-be-scaled picture, and obtains the location of the face in the to-be-scaled picture from the attribute information of the to-be-scaled picture, and the face is in the to-be-scaled The position of the picture serves as the zoom point of the picture to be scaled.

图 7为本发明图片缩放方法实施例四的流程图。如图 7所示，本实施例提供的图片缩放方法，包括： FIG. 7 is a flowchart of Embodiment 4 of a picture zooming method according to the present invention. As shown in FIG. 7, the image zooming method provided in this embodiment includes:

步骤 701、获取用户确定的标准图片的缩放区域和所述标准图片的图片类型，建立所述图片类型和所述缩放区域的对应关系，并将所述对应关系保存到所述图片信息表中； Step 701: Obtain a zoom area of a standard picture determined by a user and a picture type of the standard picture, establish a correspondence between the picture type and the zoom area, and save the corresponding relationship to the picture information table.

步骤 702、获取所述待缩放图片的图片类型，根据图片信息表确定与所述图片类型对应的缩放区域，将所述缩放区域作为所述待缩放图片的属性信息； Step 702: Obtain a picture type of the picture to be scaled, determine a zoom area corresponding to the picture type according to the picture information table, and use the zoom area as attribute information of the picture to be zoomed;

步骤 703、获取对所述待缩放图片进行缩放操作的指令； Step 703: Acquire an instruction for performing a scaling operation on the to-be-scaled picture.

步骤 704、获取所述缩放区域，确定所述缩放区域的中心点，将所述缩放区域的中心点作为所述待缩放图片的缩放点； Step 704: Obtain the zoom area, determine a center point of the zoom area, and use a center point of the zoom area as a zoom point of the to-be-scaled picture;

步骤 705、以所述缩放点为缩放中心，对所述待缩放图片进行缩放处理。在本实施例中，步骤 703与步骤 101类似，步骤 705与步骤 103类似，本实施例此处不再赘述。 Step 705: Perform scaling processing on the to-be-scaled picture by using the zoom point as a zoom center. In this embodiment, step 703 is similar to step 101, and step 705 is similar to step 103, and details are not described herein again.

在步骤 701中，首先建立图片信息表，本领域技术人员可以理解，图片信息表可以由本实施例中的用户设备建立，也可以由其它用户设备预先建立好，预存在本实施例的用户设备中。图片信息表主要作用在于根据用户的历史行为规律，确定缩放区域。 In step 701, a picture information table is first established, which can be understood by those skilled in the art. The information table may be established by the user equipment in this embodiment, or may be pre-established by other user equipments, and is pre-existing in the user equipment of this embodiment. The main function of the picture information table is to determine the zoom area according to the historical behavior of the user.

在具体实现过程中，用户设备获取用户确定的标准图片的缩放区域和所述标准图片的图片类型，建立所述图片类型和所述缩放区域的对应关系，并将所述对应关系保存到所述图片信息表中，即图片信息表用于存储图片类型和缩放区域的对应关系。 In a specific implementation process, the user equipment acquires a zoom area of the standard picture determined by the user and a picture type of the standard picture, establish a correspondence between the picture type and the zoom area, and save the corresponding relationship to the In the picture information table, the picture information table is used to store the correspondence between the picture type and the zoom area.

其中，标准图片为用户设备已经确定了缩放区域的图片。可以采集以往用户确定的待缩放图片的缩放区域，作为标准图片的缩放区域。或者，向多个用户提供多个标准图像，由多个用户确定各标准图像的缩放区域，然后采集信息，进行整合，建立图片类型和缩放区域的对应关系，并将对应关系保存到图片信息表中。图片类型具体可以为各种风景图片，各种人物图片或者各种动物图片等。例如，当图片类型为风景图片时，由于风景图片所涉及的场景较多，因此，缩放区域可以为所述风景图片的中心区域，也可以为所述风景图片的主要场景所在的区域；当图片类型为人物图片时，由于人脸多位于图像的中上部，因此，缩放区域可以为图片的中上部区域；当图片类型为动物图片时，不同的动物，其对应的缩放区域也是不同的，当该动物为飞禽时，缩放区域可以为图片的中上部区域，当该动物为陆地动物时，缩放区域可以为图片的中下部区域。对于图片类型和缩放区域的对应关系，本实施例此处不作特别限制。 The standard picture is a picture in which the user equipment has determined the zoom area. The zoom area of the image to be scaled determined by the user can be collected as the zoom area of the standard picture. Or, providing a plurality of standard images to a plurality of users, determining, by a plurality of users, a zoom area of each standard image, then collecting information, performing integration, establishing a correspondence between the picture type and the zoom area, and saving the correspondence to the picture information table. in. The picture type can be a variety of landscape pictures, various character pictures or various animal pictures. For example, when the picture type is a landscape picture, since the scene picture involves more scenes, the zoom area may be the center area of the landscape picture, or may be the area where the main scene of the landscape picture is located; When the type is a character picture, since the face is mostly located in the upper middle part of the image, the zoom area may be the upper middle area of the picture; when the picture type is an animal picture, the different zoom areas of different animals are different. When the animal is a bird, the zoom area may be the upper middle area of the picture, and when the animal is a land animal, the zoom area may be the lower middle area of the picture. For the correspondence between the picture type and the zoom area, the embodiment is not particularly limited herein.

在步骤 702中，获取待缩放图片的图片类型，在图片信息表中确定与图片类型对应的缩放区域，将缩放区域作为待缩放图片的属性信息。 In step 702, a picture type of the picture to be scaled is obtained, and a zoom area corresponding to the picture type is determined in the picture information table, and the zoom area is used as attribute information of the picture to be zoomed.

具体地，图片信息表中存储了标准图片的图片类型与缩放区域的对应关系，在获取待缩放图片的缩放点时，先获取待缩放图片的图片类型，然后将待缩放图片的图片类型与图片信息表中的标准图片的图片类型进行匹配，当待缩放图片的图片类型与图片信息表中的标准图片的图片类型一致时，将图片信息表中标准图片的图片类型对应的缩放区域作为待缩放图片的缩放区域，并作为待缩放图片的属性信息。 Specifically, the picture information table stores the correspondence between the picture type of the standard picture and the zoom area. When acquiring the zoom point of the picture to be zoomed, first obtain the picture type of the picture to be zoomed, and then the picture type and picture of the picture to be zoomed The picture type of the standard picture in the information table is matched. When the picture type of the picture to be scaled is consistent with the picture type of the standard picture in the picture information table, the zoom area corresponding to the picture type of the standard picture in the picture information table is to be scaled. The zoom area of the picture, and as the attribute information of the picture to be scaled.

例如，在获取到待缩放图片后，通过图像识别技术确定待缩放图片的图片类型为风景图片，与图片信息表中的标准图片的图片类型进行匹配，当标准图片的图片类型为风景图片时，则匹配成功，将图片信息表中该标准图片对应的缩放区域作为该待缩放图片的缩放区域，并将该缩放区域作为待缩放图片的属性信息。 For example, after the image to be zoomed is acquired, the image type of the image to be zoomed is determined by the image recognition technology to be a landscape image, and the image type of the standard image in the image information table is matched. If the picture type of the quasi-picture is a landscape picture, the matching is successful, and the zoom area corresponding to the standard picture in the picture information table is used as the zoom area of the picture to be zoomed, and the zoom area is used as the attribute information of the picture to be zoomed.

再例如，在获取到待缩放图片后，通过图像识别技术确定待缩放图片的图片类型为动物图片中的飞禽图片，与图片信息表中的标准图片的图片类型进行匹配，当标准图片的图片类型为飞禽图片时，则匹配成功，将图片信息表中该标准图片对应的缩放区域作为该待缩放图片的缩放区域，并将该缩放区域作为待缩放图片的属性信息。 For example, after acquiring the image to be zoomed, the image recognition type determines that the picture type of the picture to be zoomed is a bird picture in the animal picture, and matches the picture type of the standard picture in the picture information table, when the picture type of the standard picture When the picture is a bird, the matching is successful, and the zoom area corresponding to the standard picture in the picture information table is used as the zoom area of the picture to be zoomed, and the zoom area is used as the attribute information of the picture to be zoomed.
