Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.

It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer.

Referring to fig. 1, fig. 1 is a schematic flow chart of an imaging method of an apparatus according to an embodiment of the present disclosure, where the flow chart may include:

101. when the device is in a preview interface of the shooting application, at least one voice message is acquired.

In the embodiment of the application, the electronic equipment comprises a first camera of a first type and a plurality of second cameras of a second type, wherein the shooting area of the first camera is larger than that of the second camera, the shooting area of the second camera and the shooting area of the first camera have an overlapping part or overlap area, and the shooting areas of any two second cameras have an overlapping part, and the overlapping part of the shooting areas of any two second cameras and the shooting area of the first camera have an overlapping part, the shooting areas of the plurality of second cameras are all provided with overlapping parts, and the overlapping parts of the shooting areas of the plurality of second cameras and the shooting area of the first camera are provided with overlapping parts, that is, there is an overlapping portion where the shooting areas of the plurality of second cameras and the shooting area of the first camera overlap at the same time.

For example, when a user operates the electronic device to start a shooting class application (e.g., a system application "camera" of the electronic device), the electronic device enters a preview interface of the shooting class application. The electronic device may obtain at least one voice message when the electronic device is at a preview interface of a camera-like application.

The electronic device can acquire one or more voice messages of a user through the microphone. The electronic device may also obtain one or more voice messages from multiple users via the microphone.

For example, when the user U1 says "please help me take a photo" in the microphone pick-up range of the electronic device, the electronic device obtains a voice message through the microphone. When the user U2 says "today's weather is really good" in the microphone pick-up range of the electronic device, the electronic device obtains a voice message through the microphone.

102. And determining target voice information with preset keywords from at least one voice information, and determining a user corresponding to the target voice information as a target shooting object.

For example, after at least one voice message is acquired, the electronic device may detect whether a preset keyword exists in each voice message. For example, the electronic device may perform voice recognition on each voice message to convert the voice message into corresponding text message, and detect whether a preset keyword exists in the text message. When a certain voice message is detected to have a preset keyword, the electronic device may determine the voice message as a target voice message, and determine a user corresponding to the target voice message as a target shooting object.

For example, assume that the electronic device acquires voice information of user U1, user U2, and user U3. The speech information of the user U1 is: "please help me to take a picture", the voice information of the user U2 is: "today's weather is really good", the speech information of the user U3 is: "Sun Hai Yan". The keyword is preset as "photo". It can be known that the preset keyword "photo" exists in the voice information of the user U1, then, the electronic device may determine the voice information of the user U1 as the target voice information, and determine the user corresponding to the target voice information, that is, the user U1, as the target shooting object.

In some embodiments, each time the electronic device acquires one voice message, it may be detected whether a preset keyword exists in the voice message. If the electronic device detects that the preset keyword exists in the voice message, the electronic device may determine the voice message as the target voice message, determine the user corresponding to the target voice message as the target shooting object, and enter the process 103. If the electronic device detects that the preset keyword does not exist in the voice information, the electronic device can continue to execute the process of acquiring the voice information.

The preset keywords may be set by a user, or may be automatically generated by the electronic device, and so on. The method is not particularly limited, and is subject to practical requirements.

103. The target shooting object is shot through the first camera, and a first image obtained through shooting is set as a base image.

For example, after determining that the user U1 is the target shooting object, the electronic device may shoot the user U1 once by using the first camera, and record an image shot by the first camera as a first image, and set the first image as a base image.

In some embodiments, only the target photographic subject may be included in the first image, i.e., only the user U1. In other embodiments, the first image may include other people, objects, scenes, etc. besides the target shooting object, i.e. the user U1, and is not limited herein.

104. And shooting the target shooting object through a plurality of second cameras to obtain a plurality of second images.

In the embodiment of the application, the electronic device further shoots a target shooting object through a plurality of second cameras arranged on the electronic device, a plurality of images are correspondingly obtained, and the images shot by the second cameras are recorded as second images, namely, the plurality of second images are obtained through shooting.

It should be noted that when a target shooting object is shot by a plurality of second cameras, the second cameras and the first cameras use the same image parameters (such as contrast and brightness) to shoot, so that the first and second images shot by the first and second cameras have different image sizes and the same effect.

It should be noted that, in this embodiment of the present application, the execution order of 103 and 104 is not limited, and 104 may be executed after 103 is executed, 103 may be executed after 104 is executed, or 103 and 104 may be executed simultaneously.

105. And carrying out image synthesis processing on the plurality of second images and the substrate image to obtain an imaging image.

In the embodiment of the application, after the electronic device obtains the base image through the shooting of the first camera and obtains the plurality of second images through the shooting of the plurality of second cameras, the plurality of shot second images are aligned with the base image.

Based on the aligned base image and second image, for the overlapping portion of the base image and the second image, an average pixel value of each overlapped pixel point is calculated, for example, the electronic device obtains the base image through shooting by the first camera, and also obtains four second images through shooting by four second cameras, for the overlapping area, the pixel values of the pixel point at a certain position in five images (i.e., the base image and the four second images) are respectively 0.8, 0.9, 1.1, 1.2, and 1, and then the average pixel value of the pixel point at the position can be calculated to be 1.

Then, a composite image is obtained according to the average pixel values obtained by the corresponding pixel points at the positions in the base image, for example, the pixel values of the pixel points of the base image can be correspondingly adjusted to the average pixel values obtained by calculation, so as to obtain an imaging image; for another example, a new image, i.e., an imaged image, may be generated based on the calculated average pixel values.

In the embodiment of the application, the electronic device obtains the imaging image after performing image synthesis processing on the plurality of second images obtained by shooting and the substrate image, and thus, the electronic device completes one complete shooting operation.

In the embodiment of the present application, the target object is located in an overlapping area where the shooting areas of the plurality of second cameras and the shooting area of the first camera are all overlapped, or the target object is located in an overlapping area where the shooting areas of the plurality of second cameras and the shooting area of the first camera are simultaneously overlapped. Assume that the electronic device includes four second cameras, which are a second camera a, a second camera B, a second camera C, and a second camera D, respectively. The imaging area of the second camera a overlaps with the imaging area of the first camera, and is referred to as an overlapping area m 12. The overlapping area m12 has an overlapping area with the shooting area of the second camera B, and is referred to as an overlapping area m 13. The overlapping area m13 has an overlapping area with the shooting area of the second camera C, and is referred to as an overlapping area m 14. The overlapping area m14 is an overlapping area with the shooting area of the second camera D, and is referred to as an overlapping area m 15. The target photographic subject is located in the overlap area m 15.

In the embodiment of the application, target voice information with preset keywords is determined from at least one voice information, and a user corresponding to the target voice information is determined as a target shooting object; shooting a target shooting object through a first camera, and setting a first image obtained through shooting as a base image; shooting a target shooting object through a plurality of second cameras to obtain a plurality of second images; and carrying out image synthesis processing on the plurality of second images and the substrate image to obtain an imaging image. Because the shooting areas of the second cameras and the first camera have the overlapping parts, the shooting areas of any two second cameras have the overlapping parts, the overlapping parts of the shooting areas of any two second cameras and the shooting area of the first camera have the overlapping parts, and the target shooting object is in the overlapping areas where the shooting areas of the second cameras and the shooting area of the first camera are overlapped, the definition of the area where the target shooting object is located in the finally obtained imaging image is improved, the definition of the area outside the area where the target shooting object is located is also improved, and the quality of the whole imaging image is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of an imaging method of an apparatus according to an embodiment of the present application, where the flow chart may include:

201. when the electronic equipment is in a preview interface of the shooting application, the electronic equipment acquires at least one voice message.

The electronic equipment can acquire at least one voice message of at least one user through the microphone. For example, the electronic device may obtain one voice message of one user through the microphone, and may also obtain a plurality of voice messages of one user. The electronic equipment can acquire voice information of a plurality of users through the microphone. The electronic device may acquire one voice message of each of the plurality of users, or may acquire a plurality of voice messages of each of the plurality of users.

For example, when the user U1 says "please help me take a photo" in the microphone pick-up range of the electronic device, the electronic device obtains a voice message through the microphone, and the voice message corresponds to the user U1. When the user U2 says "today is very good" in the microphone pickup range of the electronic device, the electronic device obtains a voice message through the microphone, and the voice message corresponds to the user U2.

202. The electronic equipment determines target voice information with preset keywords from at least one voice information.

For example, if there are multiple users in the shooting scene, the electronic device may acquire one or more pieces of voice information of the multiple users at the same time. In order to improve the shooting efficiency, the electronic device may simultaneously detect whether a preset keyword exists in one or more voice messages of multiple users. For example, the electronic device may perform voice recognition on each voice message to convert the voice message into corresponding text message, and detect whether a preset keyword exists in the text message. Since there are a plurality of users in the shooting scene, there is a case where the plurality of users all say the preset keyword. For the above situation, that is, if the electronic device detects that there are at least two target voice messages with preset keywords, the electronic device may enter the process 203.

After a shooting application program (such as a system application "camera" of the electronic device) is started according to a user operation, a scene aimed at by a camera of the electronic device is a shooting scene. For example, after the user clicks an icon of a "camera" application on the electronic device with a finger to start the "camera application", if the user uses a camera of the electronic device to align a scene including an XX object, the scene including the XX object is a shooting scene. From the above description, it will be understood by those skilled in the art that the shooting scene is not specific to a particular scene, but is a scene aligned in real time following the orientation of the camera.

203. And if at least two target voice messages with preset keywords exist, the electronic equipment determines the user corresponding to each target voice message to obtain at least two users.

The electronic equipment detects that at least two target voice messages with preset keywords exist, and two situations exist. The method comprises the following steps: the electronic equipment detects that at least two target voice messages with preset keywords exist, and the at least two target voice messages with the preset keywords correspond to the same user, namely the same user speaks the at least two target voices with the preset keywords. The second is as follows: the electronic equipment detects that target voice information with at least two preset keywords exists, and each target voice information with the preset keywords corresponds to different users, namely each target voice with the preset keywords is spoken by different users.

The embodiment of the application is mainly directed to the second situation, that is, if at least two target voice messages with preset keywords exist and each target voice message with the preset keywords corresponds to a different user, the electronic device may determine the user corresponding to each target voice message to obtain at least two users.

204. The electronic device selects a target photographic subject from at least two users.

After determining the user corresponding to each target voice message and obtaining at least two users, the electronic device may select a target photographic object from the at least two users.

For example, the electronic device may determine a user at a close distance from the electronic device as a target photographic subject. Alternatively, the electronic device may determine a user located far from the electronic device as the target photographic subject.

For another example, the electronic device may obtain a plurality of face photos in a photo library. Then, the electronic device can classify each face photo according to the feature information of the face photo. For example, it is assumed that there are 20 face photos, wherein 10 face photos can extract the same first feature information, another 7 face photos can extract the same second feature information, and the remaining 3 face photos can extract the same third feature information. That is, the first feature information corresponds to 10 face photos, the second feature information corresponds to 7 face photos, and the third feature information corresponds to 3 face photos, that is, the number of face photos with the first feature information is the largest, the number of face photos with the second feature information is the next to the number of face photos with the third feature information is the smallest. Assume that the electronic apparatus needs to select a target photographic subject from 3 users. Then, the electronic device may first perform image acquisition on the 3 users to acquire 3 face images. Then, the electronic device may extract feature information of each face image to obtain 3 pieces of feature information, which are recorded as first target feature information, second target feature information, and third target feature information. Next, the electronic device may detect whether each feature information matches one of the first feature information, the second feature information, and the third feature information. And if the first target characteristic information is matched with the first characteristic information, the second target characteristic information is matched with the second characteristic information, and the third target characteristic information is matched with the third characteristic information. The electronic device may determine a user corresponding to the first target feature information as a target photographic object. And if the first target characteristic information is matched with the first characteristic information, and the second target characteristic information is not matched with the third target characteristic information, the second characteristic information and the third characteristic information, determining the user corresponding to the first target characteristic information as a target shooting object. If there are at least two pieces of feature information in the 3 pieces of feature information, for example, 2 pieces of feature information are matched with the first feature information, the second feature information, or the third feature information, the target photographic object is determined from the users corresponding to the 2 pieces of feature information, for example, any one of the users corresponding to the 2 pieces of feature information is determined as the target photographic object.

For another example, the electronic device may display a selection frame on the display screen to allow a user (a user holding the electronic device) to select which user is determined as the target photographic subject.

205. The electronic device determines a relative position of the target photographic subject and the electronic device.

In the embodiment of the application, in order to determine the relative position of the target photographic object and the electronic device, the electronic device may receive the voice information of at least one user by using a microphone array, that is, at least three microphones, when acquiring at least one voice information. After the electronic device determines the target photographic object, the electronic device may obtain the receiving time of each microphone receiving the target voice information corresponding to the target photographic object, so as to obtain the relative position of the target photographic object and each microphone according to the receiving time. The electronic equipment can determine the relative position of the target shooting object and the terminal according to the relative positions of the target shooting object and the microphones. For example, the relative position of the target speech and the electronic device is calculated through a plane geometry correlation algorithm. In the same plane, the distance from any point to the fixed three points is only one, and in the embodiment, the number of the microphones is more than three.

Wherein the relative position may be a relative position in the same plane, the relative position including a horizontal direction and a horizontal distance. Because the microphones are fixed on the electronic equipment, the positions of the microphones on the electronic equipment are known, the position distances between the microphones are also known, the propagation speed of the target voice in the air is also known, and the relative positions of the target voice and the electronic equipment, namely the relative positions of the target shooting object and the electronic equipment can be calculated by the known conditions and the receiving time of the target voice received by the microphones. For example, since the relative positions of the microphones are known, the electronic device first calculates the relative positions of the target photographic object and the microphones according to the receiving time of the microphones receiving the target voice information, then may select a reference point on the electronic device, and may obtain the relative positions of the target photographic object and the reference point on the electronic device according to the relative positions of the microphones and the reference point, so as to obtain the relative positions of the target photographic object and the electronic device.

The relative position may also be a relative position within a three-dimensional space, which includes a spatial direction and a spatial distance. Since the distances from any point to the fixed four points are unique in the three-dimensional space, another point in the three-dimensional space can be determined by any four points. In this embodiment, the number of microphones may be more than four.

It should be noted that the relative position between the target photographic object and the electronic device may also be determined in a manner not listed in the embodiment of the present application, which is not specifically limited by the embodiment of the present application.

206. The electronic equipment adjusts the shooting angle of the first camera according to the relative position so that the target shooting object is located in the central area of the shooting area of the first camera.

After the relative position of the target shooting object and the electronic device is determined, the electronic device can adjust the shooting angle of the first camera according to the relative position. For example, the electronic device may calculate an angle and a direction that the first camera needs to rotate according to the relative position, so as to rotate the first camera according to the angle and the direction that the first camera needs to rotate, so as to adjust a shooting angle of the first camera, so that the target shooting object is located in a central area of a shooting area of the first camera, that is, as shown in fig. 3.

And 207, the electronic equipment shoots a target shooting object through the first camera, and a first shot image is set as a base image.

For example, when the electronic device determines that the user U1 is the target shooting object, the electronic device may shoot the user U1 once by the first camera, mark the image shot by the first camera as a first image, and set the first image as a base image.

208. The electronic equipment adjusts the shooting angle of each second camera according to the relative position, so that the shooting area of each second camera is partially overlapped with the edge of the shooting area of the first camera.

After determining the relative position between the target shooting object and the electronic device, the electronic device may adjust the shooting angle of each second camera according to the relative position. For example, the electronic device may calculate an angle and a direction that each second camera needs to rotate according to the relative position, so as to rotate each second camera according to the angle and the direction that each second camera needs to rotate, so as to adjust a shooting angle of each second camera, so that a shooting area of each second camera overlaps with an edge portion of a shooting area of the first camera.

For example, the first camera is a standard type camera or a camera with a field angle of about 45 degrees, and the second camera is a telephoto type camera or a camera with a field angle of less than 40 degrees. The electronic equipment comprises a first camera, four second cameras, namely a second camera A, a second camera B, a second camera C and a second camera D. Referring to fig. 4 and 5 in combination, after the shooting angles of the first camera and the second cameras are adjusted according to the relative positions of the electronic device and the target shooting object, the axes of the second cameras incline and intersect with each other toward the axis of the first camera, so that the target shooting object is located in the central area of the shooting area of the first camera, the shooting area a of the second camera a corresponds to the upper left corner of the shooting area of the first camera, the shooting area B of the second camera B corresponds to the upper right corner of the shooting area of the first camera, the shooting area C of the second camera C corresponds to the lower left corner of the shooting area of the first camera, and the shooting area D of the second camera D corresponds to the lower right corner of the shooting area of the first camera, so that the shooting area of the second camera overlaps with the edge of the shooting area of the first camera, and the overlapping portion of any two shooting areas of the second camera overlaps with the shooting area of the first camera And the shooting areas of the four second cameras are overlapped with the central area of the shooting area of the first camera. And the target shooting object is located in the central area of the shooting area of the first camera, the target shooting object can be determined to be located in an area where the shooting area of the first camera and the shooting areas of the second cameras are overlapped.

For example, as shown in fig. 6, assuming that a region where the shooting region of the first camera overlaps with the shooting regions of the second cameras is an overlap region m, the target object is in the overlap region m.

209. The electronic equipment shoots the target shooting object through the second cameras to obtain a plurality of second images.

In the embodiment of the application, after the shooting angle of each of the second cameras is adjusted according to the relative position, the electronic device can shoot a target shooting object through the second cameras to obtain a plurality of images correspondingly, and the images shot by the second cameras are recorded as second images, that is, a plurality of second images are obtained through shooting.

It should be noted that when a target shooting object is shot by a plurality of second cameras, the second cameras and the first cameras use the same image parameters (such as contrast and brightness) to shoot, so that the shooting area of the second cameras is a part of the shooting area of the first cameras, but the shooting effect of the first images and the second images obtained by shooting of the second cameras is the same.

For example, the electronic device includes four second cameras, which are a second camera a, a second camera B, a second camera C and a second camera D, and the shooting areas of the four second cameras correspond to the upper left corner, the upper right corner, the lower left corner and the lower right corner of the shooting area of the first camera, respectively, and four second images are obtained by shooting through the four second cameras, as shown in fig. 7, the image content of the second image G1 shot by the second camera a corresponds to the image content of the upper left corner of the base image, the image content of the second image G2 shot by the second camera B corresponds to the image content of the upper right corner of the base image, the image content of the second image G3 shot by the second camera C corresponds to the image content of the lower left corner of the base image, the image content of the second image G4 shot by the second camera D corresponds to the image content of the lower right corner of the base image, in this way, the image content of the different second images covers different positions of the edge area in the base image, and the image content of the different second images includes the target photographic subject.

It should be noted that, in the embodiment of the present application, 205 and 207 may be executed after the execution is completed 204 and 206. For 205 and 207, 205 may be executed first and then 207 may be executed, 207 may be executed first and then 205 may be executed, and 205 and 207 may also be executed simultaneously.

210. And the electronic equipment carries out image synthesis processing on the plurality of second images and the substrate image to obtain an imaging image.

And calculating the average pixel value of each overlapped pixel point for the overlapped part of the base image and the second image based on the aligned base image and the second image. For example, the electronic device obtains four second images through four second cameras in addition to the base image through the first camera. Assume that the four second images are a second image G1, a second image G2, a second image G3, and a second image G4.

Referring to fig. 8, an overlapping area m1 where each second image and the base image overlap is located in a central area of the base image, i.e., an area where the target photographic object is located. That is, the second image G1, the second image G2, the second image G3, the second image G4, and the overlapping area m1 of the base image are located at the central area of the base image. Thus, for the overlapping area m1 shown in fig. 8, the pixel values of the pixel point at a certain position in the five images (i.e., the base image and the four second images) are 0.8, 0.9, 1.1, 1.2, and 1, respectively, and then the average pixel value of the pixel point at the position can be calculated to be 1.

With continued reference to fig. 8, the overlapping area of the second image G1, the second image G2, and the base image is an overlapping area m2, the overlapping area of the second image G1, the second image G3, and the base image is an overlapping area m3, the overlapping area of the second image G2, the second image G4, and the base image is an overlapping area m4, and the overlapping area of the second image G3, the second image G4, and the base image is an overlapping area m 5. For the overlapping area m2 shown in fig. 8, the pixel values of the pixel point at a certain position in the second image G1, the second image G2 and the base image are 0.8, 0.9 and 1, respectively, and then the average pixel value of the pixel point at the position can be calculated to be 0.9.

With continued reference to FIG. 8, the overlapping area of the second image G1 and the base image is overlapping area m6, the overlapping area of the second image G2 and the base image is overlapping area m7, the overlapping area of the second image G3 and the base image is overlapping area m8, and the overlapping area of the second image G4 and the base image is overlapping area m 9. For the overlap area m6 shown in fig. 8, if the pixel values of the pixel point at a certain position in the second image G1 and the base image are 0.8 and 1, respectively, the average pixel value of the pixel point at the position can be calculated to be 0.9.

Then, the electronic device obtains a composite image according to the average pixel values obtained by the corresponding pixel points at the positions in the base image, for example, the electronic device may correspondingly adjust the pixel values of the pixel points of the base image to the average pixel values obtained by calculation, so as to obtain an imaging image; for another example, the electronic device may further generate a new image, i.e., an imaged image, according to the calculated average pixel values. In the imaging image, the definition of the central area, namely the area where the target shooting object is located, is highest, the definition of the area where each second image overlaps with each other pairwise and overlaps with the base image is second, the definition of the overlapping area of each second image and the base image is lowest, but the overall definition of the imaging image is relatively higher compared with that of the base image.

For example, referring to fig. 9, fig. 9 shows the change of the sharpness from the base image to the imaged image, wherein the X axis represents the change from the edge area of the image to the central area, and then from the central area to the edge area, and the Y axis represents the sharpness that changes along with the X axis, it can be seen that in the base image, the sharpness of the central area is the highest, and as the central area spreads to the edge area, the sharpness gradually decreases and changes more sharply, while in the imaged image, the sharpness of the central area is the highest, and compared to the base image, the sharpness of the edge area of the imaged image is integrally improved, and as the central area spreads to the edge area, although the sharpness gradually decreases, the change is smoother, so that the overall image quality of the imaged image is improved.

As shown in fig. 10, in some embodiments, flow 204 may include:

2041. the electronic equipment performs image acquisition operation on each user to obtain at least two face images, wherein each face image corresponds to one user.

2042. The electronic equipment extracts the feature information of each face image to obtain at least two pieces of feature information.

2043. The electronic equipment determines target characteristic information matched with the preset characteristic information from the at least two pieces of characteristic information.

2044. And the electronic equipment determines the user corresponding to the target characteristic information as a target shooting object.

After determining the user corresponding to each target voice message and obtaining at least two users, the electronic device may perform image acquisition operation on each user to obtain at least two face images. Each face image corresponds to a user. Then, the electronic device may extract feature information of each face image to obtain at least two pieces of feature information. Then, the electronic device detects whether each piece of feature information matches preset feature information, and determines the feature information matching the preset feature information as target feature information. And finally, the electronic equipment determines the user corresponding to the target characteristic information as a target shooting object.

For example, there may be other unrelated people or objects in the shooting scene, and if the other unrelated people in the shooting scene happen to speak the preset keyword together with the target shooting object, the electronic device may be caused to erroneously determine the other people as the target shooting object. In order to avoid the situation, the user can store the feature information corresponding to the face photos of the user or other friends in advance, and set the feature information as the preset feature information, so that when other unrelated people happen to speak the preset keywords together with the target shooting object in the shooting scene, the situation that the electronic equipment mistakenly determines other unrelated people as the target shooting object can be avoided.

It can be understood that, in the embodiment of the present application, when a preset keyword is detected in the acquired voice information, the electronic device receives an image capturing request for a target capturing object while determining that a user corresponding to the voice information is the target capturing object. That is, when the preset keyword is detected in the acquired voice information, the electronic device performs one-time shooting on the target shooting object. Therefore, it is important to avoid a situation where the electronic device erroneously determines other unrelated persons as the target photographic subject. Based on this, in the embodiment of the application, when the preset keyword is detected in the acquired voice information, the electronic device may determine the user corresponding to the voice information. Then, the electronic equipment performs image acquisition operation on the user to obtain a face image. Then, the electronic equipment extracts the feature information of the face image. Subsequently, the electronic device detects whether the feature information matches preset feature information. Finally, if the characteristic information is matched with the preset characteristic information, the electronic equipment can determine the user as the target shooting object.

In one embodiment, the electronic device includes two first cameras, and the electronic device adjusts a shooting angle of the first cameras according to the relative position so that a target shooting object is located in a central area of a shooting area of the first cameras, including:

the electronic equipment adjusts the shooting angles of the two first cameras according to the relative positions so that the target shooting object is located in the central area of the shooting areas of the two first cameras.

The electronic device shoots a target shooting object through a first camera, and sets a shot first image as a base image, and the electronic device comprises:

(1) the electronic equipment shoots a target shooting object through two first cameras to obtain at least two first images;

(2) the electronic device performs image synthesis processing on at least two first images, and sets the synthesized images as base images.

In an embodiment of the application, the electronic device includes two standard types of first cameras. For example, referring to fig. 11, the electronic device includes two first cameras, namely a first camera E and a first camera F, and the first camera E is surrounded by four second cameras.

After the shooting angles of the two first cameras are adjusted according to the relative positions so that the target shooting object is located in the central area of the shooting areas of the two first cameras, the electronic equipment can shoot the target shooting object through the two first cameras to obtain at least two first images with the same image content. And then, carrying out image synthesis processing on at least two first images, and setting the synthesized image as a base image.

When the electronic device performs image synthesis processing on the at least two first images, the at least two first images are aligned, an average pixel value of each pixel point where the at least two first images overlap is calculated, a synthetic image of the at least two first images is obtained according to each average pixel value obtained through calculation, and the synthetic image is set as a base image.

Compared with the method that the first image shot by the first camera is directly set as the base image, the base image with higher definition can be obtained in the embodiment of the application, so that the finally obtained imaging image also has higher definition.

In one embodiment, the "electronic device captures a target capture object through a first camera, and sets a captured first image as a base image", including:

(1) the electronic equipment continuously shoots a target shooting object through a first camera to obtain a plurality of first images;

(2) the electronic device performs image synthesis processing on the plurality of first images, and sets the synthesized image as a base image.

In the embodiment of the application, after the shooting angle of the first camera is adjusted according to the relative position so that the target shooting object is located in the central area of the shooting area of the first camera, the electronic device can continuously shoot the target shooting object through the first camera to obtain a plurality of first images. The electronic equipment can shoot the target shooting object through the first camera within unit time according to the set shooting frame rate, so that continuous shooting of the target shooting object is achieved. For example, assuming that the shooting frame rate of the first camera is 15FPS, the electronic device will shoot 15 images of the target shooting object within 1 second of the unit time, and since the images all correspond to the same target shooting object and the interval of the shooting time between the images is small, the image contents of the images can be regarded as the same.

After the first images of the target shooting objects are obtained through shooting, the electronic equipment selects the first image with the highest definition from the first images, aligns other first images with the first image with the highest definition, calculates the average pixel value of each pixel point overlapped by the first images, obtains a composite image of the first images according to the average pixel values obtained through calculation, and sets the composite image as a base image.

Optionally, after the electronic device continuously captures a target capture object through the first camera to obtain a plurality of first images, the method further includes:

the electronic equipment selects an image with the highest definition from the plurality of first images obtained by shooting as a base image, and the base image is used for carrying out image synthesis processing with a second image obtained by shooting by a second camera so as to obtain an imaging image.

Generally, the sharper the image, the higher its contrast. Therefore, the contrast of an image can be used to measure the sharpness of the image.

In an embodiment, before the electronic device acquires at least one voice message when being in a preview interface of a shooting-type application, the electronic device further includes an electrochromic component covering the first camera and/or the second camera:

the electronic device switches the electrochromic component to a transparent state;

after the electronic device performs image synthesis processing on the plurality of second images and the base image to obtain an imaged image, the electronic device further includes:

the electronic device switches the electrochromic assembly to a colored state to hide the first camera and/or the second camera.

In the embodiment of the application, in order to improve the integrity of the electronic device, the electrochromic assembly is covered on the first camera and/or the second camera, so that the cameras are hidden by the electrochromic assembly when needed.

The operating principle of the electrochromic assembly will first be briefly described below.

Electrochromism refers to the phenomenon that the color/transparency of a material is changed stably and reversibly under the action of an applied electric field. Materials with electrochromic properties may be referred to as electrochromic materials. The electrochromic component in the embodiment of the present application is made of electrochromic materials.

The electrochromic assembly can comprise two conducting layers which are arranged in a stacked mode, and a color changing layer, an electrolyte layer and an ion storage layer which are arranged between the two conducting layers. For example, when no voltage (or 0V) is applied to the two transparent conductive layers of the electrochromic device, the electrochromic device will be in a transparent state, when the voltage applied between the two transparent conductive layers is changed from 0V to 3V, the electrochromic device will be in black, when the voltage applied between the two transparent conductive layers is changed from 3V to-3V, the electrochromic device will be changed from black to transparent, and so on.

In this way, the first camera and/or the second camera can be hidden by utilizing the characteristic of adjustable color of the electrochromic assembly.

In the embodiment of the application, the electronic device can switch the electrochromic assembly covering the first camera and/or the second camera to a transparent state when the shooting type application is started, so that the first camera and the second camera can shoot a target shooting object.

And after the base image is acquired through the first camera, a plurality of second images are obtained through shooting of the plurality of second cameras and finally synthesized to obtain an imaging image and the started shooting application exits, the electronic equipment switches the electrochromic assembly to a coloring state, so that the first camera and/or the second camera are/is hidden.

For example, the electronic device is provided with an electrochromic component which covers all of the first camera and the second camera simultaneously, and the color of one side of the electronic device, which is provided with the first camera and the second camera, is black, so that when the electronic device does not start shooting applications, the electrochromic component is stored in a black coloring state, and the first camera and the second camera are hidden; when the shooting application is started, the electrochromic component is synchronously switched to a transparent state, so that the electronic equipment can shoot through the first camera and the second camera; and after the imaging image is finally synthesized and the started shooting application is quitted, the electronic equipment switches the electrochromic component to a black coloring state, so that the first camera and the second camera are hidden again.

In an embodiment, before the step of the electronic device shooting a target shooting object through a first camera and setting a first shot image as a base image, the method further includes:

(1) the electronic equipment detects whether the electronic equipment is in a shaking state currently;

(2) if the electronic equipment is not in the shake state at present, shooting a target shooting object through the first camera according to an image shooting request, and setting a first image obtained through shooting as a base image.

According to the description in the above embodiments, the images captured by different cameras are finally combined to obtain the imaged image, and if the electronic device is in a shake state during the shooting process, the image contents of the images captured by different cameras are obviously different, which affects the combining effect of the imaged images.

Therefore, in the embodiment of the present application, before the electronic device captures a target capture object by using the first camera and sets a captured first image as a base image, it first determines whether the electronic device is currently in a shake state. The electronic device may determine the shaking state in a plurality of different manners, for example, the electronic device may determine whether the current speed in each direction is smaller than a preset speed, if so, determine that the electronic device is not in the shaking state (or in a stable state), and if not, determine that the electronic device is in the shaking state; for another example, the electronic device may determine whether the current displacement in each direction is smaller than a preset displacement, if so, determine that the electronic device is not in the shaking state, and if not, determine that the electronic device is in the shaking state. In addition, the judgments of the jitter states may be performed in a manner not listed in the embodiments of the present application, which is not specifically limited by the embodiments of the present application.

When it is determined that the target object is in the shake state, the electronic device captures an image of the target object through the first camera, and sets the captured first image as a base image to synthesize an obtained imaging image.

(1) if the target shooting object is not in the shaking state, the electronic equipment detects whether the target shooting object is in a static state;

(2) if the target shooting object is in a static state, the electronic equipment shoots the target shooting object through the first camera, and a first image obtained through shooting is set as a base image.

From the above description, it can be understood by those skilled in the art that, in the case that the electronic device is not in a shake state, if the target photographic object is not in a still state (for example, the target photographic object includes a moving object), the image content of the image obtained by the electronic device through the first camera and the second camera may have a large difference.

Therefore, in this embodiment of the application, when determining that the electronic device is not in the shake state at present, the electronic device does not immediately shoot the target photographic object through the first camera, but further detects whether the target photographic object is in the still state, and if it is detected that the target photographic object is in the still state, shoots the target photographic object through the first camera according to the image shooting request, and sets the shot first image as the base image to synthesize the obtained imaging image, which may specifically refer to the related description in the above embodiment, and is not described herein again.

In this embodiment, a person skilled in the art can select an appropriate manner to determine whether the target photographic object is in the still state according to actual needs, which is not specifically limited in this application, for example, an optical flow method, a residual method, or the like can be used to determine whether the target photographic object is in the still state.

In one embodiment, the first camera and the second camera share an image sensor.

For example, referring to fig. 12, the first camera and the second camera share the same image sensor, and the first camera (lens portion) and the second camera (lens portion) can project external light to different portions of the image sensor in a time-sharing manner, so as to capture an external object.

Compare in the image sensor of the independent use of many cameras of prior art, many cameras sharing image sensor can reduce the space and occupy in the embodiment of this application.

305. The electronic equipment adjusts the shooting angle of each second camera according to the relative position so that the target shooting object is in an overlapping area of the shooting areas of the plurality of second cameras.

After determining the relative position between the target shooting object and the electronic device, the electronic device may adjust the shooting angle of each second camera according to the relative position. For example, the electronic device may calculate an angle and a direction that each second camera needs to rotate according to the relative position, so as to rotate each second camera according to the angle and the direction that each second camera needs to rotate, so as to adjust a shooting angle of each second camera, so that the target shooting object is located in an overlapping area of shooting areas of the plurality of second cameras.

It is understood that the shooting area of the first camera also includes the area m11, i.e., the target photographic subject is in the shooting area of the first camera. And it is understood that the overlapping area of the photographing areas of the plurality of second cameras and the overlapping area of the photographing area of the first camera are also the area m 11. That is, the region where the target photographic subject is located is an overlapping region where the photographing region of the first camera and the photographing regions of the plurality of second cameras overlap, that is, a region m 11.
