Optionally, the selecting mode of the target image data includes at least one of the following modes by comparing the characteristic information of the image data collected by all the cameras, wherein the mode of determining the target image data with the characteristic information superior to the characteristic information of the image data collected by other cameras includes:

And (I) comparing the number of target objects in the image data of all cameras, and determining the image data with the maximum number of target objects as the target image data.

That is, the feature information of the image data is the number of target objects, for example, when shooting people, the target image data is determined according to the number of people, especially in a big photo, each camera is set based on the position, the number of people that can be acquired is different, in this embodiment, the image data acquired by the camera with the largest number of target objects is used as the target image data, and then displayed on the preview interface, so that when shooting photos, a plurality of cameras act, the probability of acquiring all target objects is improved, and the purpose of the photo combination can be achieved without adjusting the position, and the shooting effect is improved.

Secondly, comparing the positions of target objects in the image data of all cameras, and determining the image data of the positions of the target objects at the preset positions of a preview interface as the target image data;

optionally, the feature information of the image data is a target object position, such as a display position of the target object relative to a preview interface. If the target object is a person, identifying whether the position of the target object is a preset position (middle position or optimal display position such as middle next two grid positions and the like) of the preview interface, taking image data of the target object position at the preset position of the preview interface as target image data, and displaying the target image data on the preview interface, so that a picture formed based on the preview data of the preview interface is better in display effect of the person, and photographing effect is improved.

And thirdly, comparing the object definition in the image data of all cameras, and determining the image data with the clearest object definition as the object image data.

Optionally, when the feature information of the image data is the object definition, if the object is a person, the clearest image data is used as the object image data by identifying the definition of the person in the image data collected by each camera, so that when the object image data is displayed in the preview interface, a clear display effect is achieved, and the photographing effect is improved.

And fourthly, comparing the brightness of the target object in the image data of all cameras, and determining the image data with the brightest brightness of the target object as the target image data.

And fifthly, comparing the image resolutions of the image data of all cameras, and determining the image data with the highest image resolution as the target image data.

Optionally, the feature information of the image data is image resolution of the image data, by comparing resolutions of the image data collected by the cameras, when the image data with the highest resolution is used as the target image data, and the target image data is displayed in the preview interface, the displayed image data has high resolution, so that the display effect of the image is improved, and a better photographing effect is achieved.

Optionally, the comparing the characteristic information of the image data collected by the camera with the characteristic information in the step of determining the target image data with the characteristic information better than the characteristic information of the image data collected by other cameras may be based on the setting by the user, or may also be determined based on the shooting type, for example, before step S20, the shooting type is obtained, the characteristic information is determined according to the shooting type, and then the characteristic information of the image data collected by each camera is compared, so as to determine the target image data with the characteristic information better than the characteristic information of the image data collected by other cameras. That is, the feature information may be different based on different settings of the user or different based on the photographing type, and thus, different feature information acquires the target image data in different manners.

If the shooting type is a person, giving a higher weight to the number of target objects or the positions of the target objects, preferentially comparing the number of the target objects or the positions of the target objects in the image data of each camera, and then determining the image data with the maximum number of the target objects as the target image data; and/or image data of the target object position at a preset position of a preview interface. When a person is photographed, the photographing purpose is mainly to display the person, so that target image data is determined based on the number of target objects and the positions of the target objects, the obtained image data meets the requirements of users, and the photographing effect is improved.

If the shooting type is a scene, the characteristic information such as the object definition or the image resolution is given higher weight, the image data with the clearest object definition is determined as the object image data by comparing the object definition or the image resolution in the image data of each camera, and/or the image data with the highest image resolution is determined as the object image data. Because the saliency of the scenery is different from that of the person, the display effect of the scenery can be improved by acquiring an image with higher definition or higher image resolution, so that the photographing effect of the scenery is improved.

According to the embodiment, the characteristic information corresponding to different shooting types is different, or the characteristic information corresponding to different settings of the user is different, so that in the shooting process, image data which meets the requirements can be correspondingly acquired as target image data based on different requirements, the acquisition probability of better image display effect is improved, and the shooting effect is improved.

Optionally, the target image data may also be determined in combination with at least two of the above-mentioned number of target objects, target object position, target object sharpness, target object brightness and image resolution. Optionally, the number of target objects, the target object position, the target object definition, the target object brightness and the image resolution are correspondingly provided with weights, and the target image data is preferentially determined based on the weights. And if the number of the target objects is the largest, determining target image data according to the number of the target objects, if the number of the target objects is a plurality of the target image data, determining the target image data according to the characteristic information with the weight smaller than the number of the target objects, and if the number of the target objects is smaller than the number of the target objects, determining the target image data according to the position corresponding to the target.

Alternatively, the respective weights corresponding to the feature information may be determined or generated based on user settings, or based on user usage habits or big data analysis, or may be different based on different shooting scenes.

Alternatively, the present embodiment may be applied to all photographing modes, or may be applied only to a group photo mode and/or a panoramic mode.

In this embodiment, at least two cameras are controlled to collect image data during photographing; then, determining target image data with characteristic information superior to that of the image data acquired by other cameras based on the characteristic information of the image data acquired by the cameras; and displaying the target image data on a preview interface of the mobile terminal. Based on selecting better image data from the image data acquired by at least two cameras as a final display image, compared with the case that only one camera is adopted to acquire the image, the embodiment can avoid the situation that the image acquired by one camera is unclear and the current shooting effect is poor, and the shooting effect of the embodiment is better.

Second embodiment:

referring to fig. 7, the step of determining target image data with characteristic information superior to characteristic information of image data collected by other cameras based on the first embodiment, optionally, includes:

Step S21, comparing the number of target objects in the image data of all cameras, wherein optionally, the characteristic information comprises the number of target objects;

step S22, judging whether the number of target objects in all the image data is consistent;

if so, that is, if the number of target objects in all the image data is consistent, step 23 is executed, and the image data with display characteristics superior to those of the image data acquired by other cameras is used as the target image data.

Optionally, the feature information may further include a display feature, and optionally, the display feature includes at least one of a display position of the target object, a display definition of the target object, a display brightness of the target object, and an image resolution.

In this embodiment, the feature information includes the number of target objects, and by comparing the number of target objects in the image data of all the cameras, it is determined whether the number of target objects acquired by each of the cameras is consistent. If the number of the cameras is 10, or the same number is all determined by identifying the number of the target objects when the 10 persons are in the group photo. If so, it is indicated that all cameras select the combined frames in the picture, or the number of people selected by each camera frame in the picture is consistent, and at this time, the target image data for final display cannot be determined by the number of target objects.

Based on this, the feature information in the present embodiment may further include display features such as at least one of a display position of the target object, a display sharpness of the target object, a display brightness of the target object, and an image resolution. When the target image data cannot be acquired through the number of target objects, the target image data is determined through the display characteristics. Such as image data at a preset position of the preview interface based on the display position of the target object, as target image data. Or based on the image data with the highest display definition of the target object as the target image data, or based on the image data with the brightest display brightness or highest image resolution of the target object as the target image data.

Therefore, the embodiment determines the target image data based on the number of target objects in combination with the display characteristics, and makes the display effect of the target objects better while meeting the requirement of the number of target objects.

Optionally, if not, that is, when the number of the target objects is inconsistent, executing step S24 to obtain the target image data with the largest target number;

step S25, identifying the target image data and target objects of other image data acquired by other cameras;

And step S26, if the target object in the other image data is inconsistent with the target object of the target image data, updating the target image data by adopting the image data synthesized by the other image data and the target image data.

It should be noted that, the target object inconsistency refers to that the target object in the target image data does not correspond to the target object in other image data one by one, for example, the target image data has an a member, a B member, and a C member, and the other image data has an a member and a D member, and optionally, the D member is the target object inconsistent with the target image data. The present embodiment can identify each of the target objects by face recognition technology.

In the process of the assembly, if the number of the target objects is inconsistent, the following situations generally exist:

first, the image data collected by at least one camera includes all the persons, and the image data collected by at least one camera includes only part of the persons (i.e. part of the persons are not framed in the picture). E.g. 10 persons in a group, whereas the image data of one camera comprises 10 persons and the image data of the other camera comprises 7 persons.

Second, the image data collected by all cameras only contains part of the group photo persons, and the number of people collected by each camera is different and has overlapped part of the group photo persons. If 10 persons are combined, 8 persons are collected by one camera, and 7 persons are collected by the other camera.

Thirdly, the image data collected by all cameras only comprise part of the group photo personnel, the number of people collected by each camera is different, and no overlapping people exist. If 10 persons are combined, one camera captures 5 persons, and the other camera captures 5 other persons.

In some alternative embodiments, the image data with the largest number of target objects is taken as target image data to ensure that the largest number of target objects are contained in the captured image.

In some alternative embodiments, in order to further improve the shooting effect, more or even all target objects are shot in the image, if the number of the target objects is inconsistent by comparing the image data acquired by the cameras, face recognition is started, whether the target objects of other image data acquired by other cameras except the target image data are consistent with the target objects in the target image data is identified, other objects inconsistent with the target objects in the target image data are determined, and the target image data is updated by adopting the image data synthesized by the other image data and the target image data.

In this embodiment, if the number of the target objects is inconsistent, the image data with the largest number of the target objects may be compared with other image data, and there may be some target objects that are not framed in the frame, and in order to ensure that the photo taking is completed, the other image data and the target image data are combined to form more complete target image data, so that the photo taking effect is improved by displaying the photo taking with more complete numbers of people in the preview interface of the mobile terminal.

Third embodiment:

referring to fig. 8, the step of updating the target image data with the image data synthesized by the other image data and the target image data may further include:

step S261, acquiring a non-overlapping area of the other image data relative to the target image data;

step S262, splicing the image data of the non-overlapping area to a splicing position corresponding to the target image data;

and step S263, taking the spliced image data as the target image data.

When it is determined that the other image data has another object different from the target object in the target image data, it is interpreted that a non-overlapping region exists between the other image data and the target image data. That is, the non-overlapping area refers to an area with different data contents in the image data collected by each camera.

Scanning each image data to obtain a non-overlapping region and an overlapping region, wherein the boundary position between the overlapping region and the non-overlapping region is the splicing position, then carrying out matting processing on the non-overlapping region in other data, splicing the non-overlapping region to the splicing position corresponding to the target image data, completing splicing of the image data, and then taking the spliced image data as the target image data to be displayed on a preview interface of the mobile terminal.

In order to enable the spliced images to be fused and natural, in the process of splicing the images, after the image data of the non-overlapping area are aligned to the corresponding positions of the target image data, the image textures and/or colors of the splicing positions are adjusted, so that the similarity of the splicing positions is similar.

Optionally, the image features include at least one of texture and/or color, and the similarity is determined based on at least one of texture differences and/or color differences. The smaller the texture difference and/or the smaller the color difference, the greater the similarity of the splice locations.

In an embodiment, the similarity is determined based on a difference value of colors or textures corresponding to at least one point divided by the splicing position, and if the difference value of colors or textures corresponding to up to a preset number of points in the splicing position is smaller than a preset difference value, the similarity of the splicing position is determined to be greater than or equal to the preset threshold.

In some embodiments, the similarity is determined based on a sum of difference values of colors and/or textures corresponding to at least one point of the splice location division. If the color and/or texture difference value of the point corresponding to one camera and the color and/or texture difference value of the point corresponding to the other camera are obtained, the texture difference and/or the color difference are added to be used as comparison values, for example, the absolute value difference value C= |Ti1-Ti2|+|Ci1-Ci2| of the texture and/or the image color of the ith point of one camera and the ith point of the other camera is smaller, and the similarity is more similar.

In the specific adjustment process, adjusting according to the color difference or the texture difference, for example, adjusting the color of the non-overlapping area in the other data by taking the color in the target image data as a reference, so that the difference between the color of the target image data and the color of the non-overlapping area of the other data is minimized; or, taking the texture in the target image data as a reference, adjusting the texture of the non-overlapping area in the other data, so that the difference between the texture of the target image data and the texture of the non-overlapping area of the other data is minimized, and image stitching is realized.

Optionally, after adjusting the image features of the stitching position between the target image data and the image data of the non-overlapping region, fusing the stitching position. And if the splicing position is subjected to natural transition fusion processing, fusing the non-overlapping region with the target image data, and improving the display effect of the image.

According to the embodiment, the non-overlapping area of the image data collected by other cameras and the target image data is spliced into the target image data, so that the display view angle of the image data displayed on the preview interface is wider, and the photographing effect of the combined photo is improved.

Fourth embodiment:

referring to fig. 9, the step of displaying the target image data on the preview interface of the mobile terminal according to the present embodiment may further include:

step S40, identifying a target object at a preset position of the preview interface;

and S50, outputting adjustment prompt information when the target object at the preset position is incomplete.

Alternatively, the preset position may be an edge position, or other positions.

The following description is made by taking the target object as an example:

in order to avoid that part of human body is not selected into the preview interface in a frame manner, so that part of human body only collects part of human body and the photographing effect is affected, the embodiment forms the target image data based on the embodiments, after the preview interface of the mobile terminal displays the target image data, identifies a target object at a preset position of the preview interface (generally, the target object at the edge of the preview interface only collects part of the position), and if the target object at the preset position is identified to be incomplete, outputs adjustment prompt information.

Optionally, in this embodiment, whether only a part of the face is collected is identified by using a face recognition manner, or whether only a part of the body is collected is identified by using a human body identification manner, so as to determine that the target object is incomplete.

Optionally, in the embodiment of the folding screen, when the target object at the preset position is incomplete, the range acquired by the camera may be adjusted by prompting the user to rotate the folding angle of the folding screen, so as to re-execute the above embodiments to regenerate the target image data on the preview interface. It should be noted that, after the folding angle of the folding screen is adjusted, the image range collected by the cameras located on the two screens can be adjusted, so that the overlapping area is reduced, the collection viewing angles of the two cameras are increased, and the target object at the preset position can be collected to a complete image. It can be understood that if the camera is a front camera, the folding angle is prompted to be increased, that is, the folding screen is unfolded. If the camera is a rear camera, prompting to reduce the folding angle, namely folding the folding screen.

In the non-folding screen embodiment, when the target object at the preset position is incomplete, the user can be prompted to adjust the position of the mobile terminal, so that the distance between the camera and the target object is more, the field of view range of the camera is enlarged, and the target object at the preset position can be acquired into a complete image.

Fifth embodiment:

referring to fig. 10, the present application further provides a photographing method, which includes:

step S210, controlling at least two cameras to acquire image data;

step S220, identifying a target object of the image data acquired by the camera;

step S230, when the target objects are inconsistent, generating target image data according to the image data acquired by all cameras;

and step S240, displaying the target image data on a preview interface of the mobile terminal.

It should be noted that, the inconsistency of the target objects means that the target objects in the image data collected by at least one camera are not in one-to-one correspondence with the target objects in the image data collected by other cameras, for example, the image data collected by the first camera has a member a, a member B and a member C, and the image data collected by the second camera has a member a and a member D.

When the target objects in the image data collected by the cameras are in one-to-one correspondence, the target objects are consistent, for example, the image data collected by the first camera is provided with an A member, a B member and a C member, and the image data collected by the second camera is also provided with the A member, the B member and the C member.

Optionally, the present embodiment identifies whether the target objects in the image data acquired by the cameras are consistent through a face recognition technology.

When the target objects are consistent, the target image data may be determined based on the display characteristics of the image data, for example, the image data with the display characteristics being better than those of the image data acquired by other cameras is taken as the target image data, and optionally, the characteristic information may further include the display characteristics, where the display characteristics include at least one of the display position of the target object, the display definition of the target object, the display brightness of the target object, and the image resolution.

The application scene of the embodiment is the same as that of the first embodiment, except that after controlling at least two cameras to collect image data, the embodiment directly identifies target objects in the image data collected by each camera, and judges whether the target objects collected by each camera are consistent. When the target objects are inconsistent, the following cases (taking the synopsis as an example) exist:

1. the number of target objects is the same, but all cameras collect part of people, and non-repeated people exist in the collected people. If 10 persons are combined, 5 persons are included in the image data of one camera, and 5 persons are included in the image data of the other camera.

2. The number of target objects is different, but all cameras collect part of the personnel. If 10 persons are combined, 6 persons are included in the image data of one camera, and 8 persons, optionally only four persons, are included in the image data of the other camera.

Based on the above, when the target objects are inconsistent, the target image data is generated according to the image data acquired by all cameras, so that when the target image data is displayed on the preview interface, more pictures of the target objects are presented, and when the target image is generated based on the preview data of the preview interface, an image with better photographing effect can be obtained, for example, when the target image is combined, a more complete photographing position of a combined camera can be obtained more easily, and the user does not need to move the position of the adjustment terminal back and forth.

Sixth embodiment:

the present embodiment is based on the fifth embodiment, and optionally, the step of generating the target image data according to the image data acquired by all the cameras includes:

target image data is generated based on the adjusted image data.

When the fact that the target objects collected by the cameras are inconsistent is determined, the fact that all the cameras collect only part of the target objects is indicated, and at the moment, the images collected by the cameras are spliced to form more complete target image data.

Optionally, when the image data collected by each camera does not have the overlapping area, each image data is directly spliced to obtain the target image data.

Optionally, if the image data collected by each camera is identical, it is indicated that each image data has an overlapping area and a non-overlapping area. Image data acquired by a target camera is predetermined, then image data acquired by other cameras are scanned, a non-overlapping area which is not overlapped with the image data acquired by the target camera is acquired, and then the non-overlapping area is aligned to a splicing position of the image data acquired by the target camera. Optionally, a boundary position between a non-overlapping region of the image data and the overlapping region is the stitching position.

Alternatively, the non-overlapping areas of the other cameras may be processed in a matting manner.

In order to enable the spliced images to be fused and natural, in the process of splicing the images, after the image data of the non-overlapping area are aligned to the corresponding positions of the image data acquired by the target camera, adjusting the image textures and/or colors of the spliced positions, so that the similarity of the spliced positions is similar.

In some embodiments, the similarity is determined based on a sum of difference values of colors and/or textures corresponding to at least one point of the splice location division. If the color and/or texture of the point corresponding to one camera and the difference value of the point and the texture corresponding to the other camera are obtained, the difference value of the texture difference and/or the color difference is added to be used as a comparison value, for example, the smaller the absolute value difference value C= |Ti1-Ti2|+|Ci1-Ci2| of the texture and/or the image color of the ith point of the one camera and the ith point of the other camera is, the more similar the similarity is.

In a specific adjustment process, adjusting according to the color difference or the texture difference, for example, adjusting the color of the non-overlapping area in the other data by taking the color in the target image data as a reference, so that the difference between the color of the target image data and the color of the non-overlapping area of the other data is minimized; or, taking the texture in the target image data as a reference, adjusting the texture of the non-overlapping area in the other data, so that the difference between the texture of the target image data and the texture of the non-overlapping area of the other data is minimized, and image stitching is realized.

Optionally, the step of generating the target image data based on the adjusted image data includes: performing fusion processing on the splicing position based on the adjusted image data; the target image data is generated based on the processed image data. And after adjusting the image characteristics of the splicing position between the target image data and the image data of the non-coincident region, fusing the splicing position. And if the splicing position is subjected to natural transition fusion processing, fusing the non-overlapping region with the target image data, and improving the display effect of the image.

Optionally, the target camera in this embodiment may be set by a user, and if the user realizes that the camera 1 is set as a main camera and the other cameras are auxiliary cameras, after the image data is collected, the image data collected by the other cameras are spliced into the image data collected by the main camera.

Or, the target camera may be determined based on the acquired image resolution, for example, a camera corresponding to image data with high image resolution is the target camera, and an image with low image resolution is the other cameras.

In the image stitching process, the stitching position is processed, so that the stitched images are displayed naturally, and the display effect of the images is improved.
