For example, after the user finishes shooting the scene shown in any one of fig. 4a to 4e, the user may click a shooting button to finish shooting. The mobile phone responds to the received user operation and saves the acquired image. Illustratively, the user may view the captured images through a gallery of the cell phone. FIG. 5 is an exemplary illustration of a gallery display. Referring to fig. 5 (1), for example, thumbnails of one or more photos or videos, such as thumbnail 502, may be displayed in the gallery interface 501. In fig. 5 (1), the thumbnail images are illustrated with a ratio (i.e., length: height) of 1. In other embodiments, the ratio of the thumbnails in the gallery interface 501 may be other values, for example, the preset ratio (long: high) of the thumbnails may be 3. Of course, the shape of the thumbnail may be other than the rectangle shown in (1) of fig. 5. For example, the shape may be circular or other polygonal shapes, and the application is not limited thereto.

Illustratively, in the gallery, thumbnails of images or videos are displayed, except in the method shown in (1) of fig. 5, that is, in the set scale (e.g., 1. Referring to fig. 5 (2), the gallery interface 503 may illustratively display thumbnails of one or more images or videos. Each thumbnail is displayed in the original scale of the image or video. For example, if the thumbnail 504 has a scale (length: height) of 3.

Fig. 6 is an exemplary illustration of an album display. Referring to fig. 6 (1), for example, when the user clicks on the album option, the mobile phone may display an album interface 601 in response to the received user operation. The album interface 601 may include one or more album covers. Each album cover may correspond to an album. Taking the camera album cover 602 as an example, the camera album cover may be displayed according to a preset ratio (for example, 1. In the embodiment of the present application, the proportion of each album cover displayed in the album is the same, and is, for example, 1. In other embodiments, the proportion of the album cover may also be set according to implementation requirements, and the present application is not limited.

Referring to fig. 6 (2), for example, each album cover displayed in the album interface 601 may be displayed in a preset scale. For example, the preset ratio (length: height) of the camera album cover 603 is 4. The above proportions are merely illustrative examples and are not intended to be limiting in this application.

Fig. 7a to 7f are schematic diagrams illustrating generation of thumbnails or album covers. Referring to (1) of fig. 7a, for example, in the embodiment of the present application, the album cover of each album may be generated based on the latest saved picture or video in the album. For example, please refer to (2) of fig. 7a, taking the cover of all photo albums as an example. Illustratively, the most recently saved of all photo albums is a video file. The video comprises a plurality of image frames (which may be, for example, 180 image frames). In one example, the cell phone may generate a cover for all photo albums based on the first image frame of the video. In another example, the mobile phone may select one image frame with the best image quality from the first 20 image frames (which may be set according to actual requirements and are not limited in this application) (the selection method may refer to the prior art and is not limited in this application), and of course, may also select one image frame from the first 20 image frames arbitrarily. With reference to (1) of fig. 7a, in this embodiment, for example, the mobile phone selects an image frame 701 with the best image quality from the first 20 image frames in the video. After the image frame 701 for generating the cover is selected by the mobile phone, the mobile phone can cut the image frame 701 based on the preset proportion of the covers of all photo albums. Referring to fig. 7a (2), an example is described in which the preset ratio (length: height) of all photo album covers is 3. Accordingly, the cell phone may crop the image frame 701 based on a crop box with a ratio of 3. Still referring to fig. 7a (1), for example, the cell phone may crop the image frame based on the cropping box 703. Illustratively, the geometric center of the cropping frame 703 coincides with the geometric center of the image frame 701, and none of the four borders of the cropping frame 703 exceeds the four borders of the image frame 701, for example, the left and right borders of the cropping frame 703 overlap the left and right borders of the image frame 701, and the top and bottom borders of the cropping frame 703 are within the image frame 701. Referring to fig. 7a (2), for example, after the mobile phone scales down the cropped image (for example, down by 50%), an all photo album cover 702 is displayed at a designated position of the album interface.

Fig. 7b is a schematic diagram of an exemplary thumbnail image with a generation scale of 1. Referring to (1) of fig. 7b, for example, a video file is still taken as an example. When the mobile phone generates the thumbnail of the video file in the gallery, the mobile phone can select the image frame for generating the thumbnail from the video. The selection manner is as above, the first image frame may be selected, and the image frame with the best image quality in the first 20 image frames may also be selected, which is not limited in the present application. Illustratively, the image frame 701 is still selected by the mobile phone. The mobile phone crops the image frame according to a preset scale (for example, 1. The cutting method is as described above, and is not described herein again. Referring to fig. 7b (2), the mobile phone scales down the cropped image to generate a thumbnail 705.

Fig. 7c is a schematic diagram illustrating an example of generating an album cover based on a double shot video. Referring to fig. 7c (1), the mobile phone can select the image frame 706 of the video for generating all photo album covers. The selection method can be referred to the above, and is not described herein.

The cell phone crops the image frame 706 based on the same crop box 707 as the preset ratio 3 (length: height) of all photo album covers. Referring to fig. 7c (2), the mobile phone generates an all photo album cover 709 based on the cut image. Referring to fig. 7c (3), the mobile phone selects the image frame 706 for generating a camera album cover. The cell phone may crop the image frame 706 based on the same crop box 708 as the preset ratio of 4 (length: height) of the camera album cover. Referring to (2) of fig. 7c, the mobile phone generates a camera album cover 710 based on the cropped image. The undescribed parts can refer to the related description of fig. 7a, and are not described again here.

Fig. 7d is a schematic diagram illustrating exemplary generation of a thumbnail based on a two-shot video. Referring to fig. 7d (1), the phone can select the image frame 706 of the video for generating all photo album covers. The selection method can be referred to the above, and is not described herein. The cell phone crops the image frame 706 based on the same cropping frame 711 as the preset ratio of thumbnail 1 (length: height). Referring to fig. 7d (2), the mobile phone generates a thumbnail 712 based on the cropped image, as an example.

Fig. 7e is a diagram illustrating exemplary generation of an album cover based on picture-in-picture captured video. Referring to fig. 7e (1), the mobile phone can select the image frame 713 of the video for generating all photo album covers. The selection method can be referred to the above, and is not described herein. The phone crops the image frame 713 based on the same crop box 714 as the preset ratio of 3 (length: height) for all photo album covers. Referring to fig. 7e (2), the mobile phone generates an all photo album cover 715 based on the cropped image. Referring to fig. 7e (3), the mobile phone selects the image frame 713 for creating a camera album cover. The phone may crop the image frame 713 based on the same crop box 716 as the preset ratio of 4 (length: height) of the camera album cover. Referring to fig. 7e (2), the mobile phone generates a camera album cover 717, for example, based on the cut image. The undescribed part can refer to the description related to fig. 7a, and the description is omitted here.

Fig. 7f is a schematic diagram illustrating exemplary generation of a thumbnail based on picture-in-picture captured video. Referring to fig. 7f (1), the phone can select the image frame 713 of the video for creating all photo album covers. The selection method can be referred to the above, and is not described herein. The cell phone crops the image frame 713 based on the same crop box 718 as the preset ratio 1 (length: height) of the thumbnail image. Referring to fig. 7d (2), the mobile phone generates a thumbnail 719, illustratively, based on the cropped image.

Obviously, in fig. 7c to 7f, since the thumbnail or the album cover generated based on the two-shot image and the pip image needs to be cut according to the preset ratio, for the two-shot image, the upper part image and the lower part image in the two-shot image may be divided, for example, only one part of the upper part image and only one part of the lower part image are left, for example, all the photo album covers 709, the camera album cover 710 and the thumbnail 712. For picture-in-picture taken images, it may result in the absence of small images in the picture-in-picture (i.e., images in a small window, which may also be referred to as small pictures), such as all-photo album cover 715, camera album cover 717, thumbnail 719. This may cause information of the generated thumbnail and cover to be lost and affect the beauty.

The embodiment of the application provides a generation mode of a thumbnail or a cover map, and attractiveness of the thumbnail and a cover of an album can be improved. Fig. 8a is a schematic diagram illustrating an exemplary flow for selecting a preselected image. Illustratively, the preselected image is optionally an image used to generate a thumbnail or album cover. Referring to fig. 8a, the method specifically includes:

and S101, starting recording.

Illustratively, the handset initiates recording in response to a received user instruction. Illustratively, a camera of the mobile phone (including a front camera and/or a rear camera) starts to acquire images. Referring to the schematic diagram of the software structure in fig. 3, for example, the camera driver may obtain an image acquired by the camera, and the camera application may perform corresponding processing on the image acquired by the camera driver. Exemplary, processing of images by a camera application optionally includes, but is not limited to: rendering the image, such as adding filters and the like; the camera application can also display images acquired by the camera in a display interface of the mobile phone. And, in embodiments of the present application, the camera application may also be used to select a preselected image. Namely, S102 to S110 are executed.

For example, referring to fig. 9a, the camera application interface 901 illustratively includes one or more controls, such as but not limited to: portrait control, photo control, video control, and more controls 902, and the like. The user may click on more control 902. Referring to fig. 9b, the camera application illustratively displays more settings boxes 903 in response to the received user operation. Illustratively, the more settings box 903 includes one or more options corresponding to the shooting mode, including but not limited to: slow motion option, black and white art option, delayed photography option, panoramic option, double shot option 904, picture-in-picture recording 905, and the like. It should be noted that, in the embodiment of the present application, a mobile phone supporting dual-view video is taken as an example for description. In other embodiments, if the electronic device supports multiple shots, for example, three shots or four shots may be supported, and the more setting box 903 may include corresponding options, for example, a two shot option, a three shot option, and the like.

Still referring to fig. 9b, for example, the user may click the corresponding option according to the requirement, so that the mobile phone performs shooting in the designated mode. For example, the user may click on the dual video option 904. The camera application initiates a dual-view recording mode, such as invoking a front-facing camera and a rear-facing camera to simultaneously capture images, in response to the received user operation. And starts recording the double-scene video after receiving that the user clicks the recording option 906. For another example, the user may click on the pip recording option 905, and the handset starts the pip recording mode in response to the received user operation, for example, invoking the front camera and the rear camera to simultaneously capture images. And upon receiving a user click on record option 906, begin recording picture-in-picture video.

And S102, detecting a mode.

For example, a camera application may detect a current video recording mode. Optionally, in this embodiment of the present application, the video recording mode includes but is not limited to: single shot mode, multiple shot mode, picture-in-picture mode, etc.

In one example, if the camera application detects that the current shooting mode is the monoscopic shooting mode, the processing may be performed according to the prior art, and the description of the present application is not repeated.

In another example, if the camera application detects that the current shooting mode is the multi-view shooting mode, for example, the current shooting mode may be a dual-view shooting mode. Then, S103 is executed.

In yet another example, if the camera application detects that the current photographing mode is a picture-in-picture photographing mode, S110 is performed.

For example, in the embodiment of the present application, the camera application may determine the current video recording mode based on the received user operation. For example, as described above (described in connection with fig. 9 b), the user may select the dual view shooting mode (i.e., click on the dual view shooting option 904), and accordingly, the camera application may determine that the current shooting mode is the dual view shooting mode in response to the received user click operation. For another example, if the user selects the pd mode (i.e., clicks on pd option 905), the camera application determines that the current capture mode is the pd mode in response to the received user click.

S103, detecting the number of people in the picture.

For example, the camera application may detect a plurality of pictures photographed in a multi-view photographing mode. For example, in the dual-view shooting mode, the preview interface of the mobile phone displays two pictures, one picture optionally displays an image acquired by the front camera, and the other picture optionally displays an image acquired by the rear camera. The camera application may detect two pictures to detect the number of people in each picture. In the embodiment of the present application, the "person" may be a front face of the portrait, a side face of the portrait, a back shadow of the portrait, or the like, and the present application is not limited thereto. In other embodiments, only the frontal portrait may be designated as "person" and other non-frontal portraits, such as landscapes or backgrounds of people, may be classified as "non-people". The specific division can be according to actual need, and this application does not make a limitation.

In one example, if the camera application detects that one person is included in the plurality of pictures, a picture including the person is selected from the plurality of pictures as a preselected image, i.e., S104 is performed.

In another example, if the camera application detects that a plurality of persons are included in the plurality of pictures, S105 is performed.

In yet another example, if the camera application detects that no person is included in the plurality of pictures, S107 is performed.

In one possible implementation, if multiple people are in one frame, for example, there are multiple people in one frame, and no people are included in another frame, for example, the frame may be a landscape. In this example, a character screen may be selected as the preselected image.

S104, selecting a character picture.

S105, detecting whether the owner is included.

For example, after the camera application detects that the plurality of pictures include a plurality of people, it may further detect whether the owner is included in the plurality of people. Optionally, in this embodiment of the application, a facial image of the owner may be stored in the mobile phone, and the camera application may call the facial image of the owner stored in the mobile phone, and match features of the multiple persons with the facial image features of the owner to identify whether the owner is included in the multiple persons. The specific image recognition process may refer to the existing image recognition technology, and is not described herein again. Alternatively, the face image of the individual may be saved by the user when the entry face is unlocked. Alternatively, the facial image of the owner may also be the facial image of the owner that is entered by the camera application after the user starts the camera application.

In one example, if the owner is included in the plurality of persons, the camera application selects a screen including the owner as the preselected image, i.e., S106 is performed.

In another example, if the individual is not included in the plurality of persons, S107 is performed.

S106, selecting the main picture.

S107, detecting whether the parameters of different lenses are the same.

In an exemplary multi-scene shooting scene, a mobile phone calls two or more cameras to shoot and displays pictures collected by different cameras. As noted above, the parameters of the multiple cameras of the cell phone are optionally different, for example, the cell phone has a wide angle camera of 1600 ten thousand pixels, a super-sensitive camera of 5000 ten thousand pixels, a tele camera of 800 ten thousand pixels, and a front camera of 800 ten thousand pixels. The camera application may detect whether the camera parameters for each picture are the same based on different cameras corresponding to different pictures. For example, in the embodiment of the present application, the camera parameter corresponding to each picture may also be understood as a shooting parameter corresponding to each picture.

In another example, if the parameters of the lens corresponding to each frame are different, the camera application may select the frame of the specified lens as the preselected image, i.e., execute S108. For example, in the dual-scene shooting mode, the mobile phone calls a front camera with 800 ten thousand pixels and a wide-angle camera with 1600 ten thousand pixels to shoot. When the camera application detects that the parameters of the cameras corresponding to the two pictures are different, the camera application can select the specified camera, for example, the picture corresponding to the front camera can be used as a preselected image. Alternatively, the camera application may preset the priority of the shot selection, for example: the super-sensitive camera with the front camera more than 5000 ten thousand pixels and the wide-angle camera with the front camera more than 16000 ten thousand pixels and the telephoto camera with the front camera more than 800 ten thousand pixels, and the camera application can select the picture of the corresponding lens as a preselected image based on the priority. The above selection is only an illustrative example, and the present application is not limited thereto.

In another example, if the parameters of the lens corresponding to each frame are the same, the camera application may select the frame as the preselected image according to a preset rule, i.e., execute S109. For example, in the double-view shooting mode, the mobile phone calls a front camera with 800 ten thousand pixels and a rear camera with 800 ten thousand pixels, and the camera application detects that the parameters of the cameras corresponding to the two pictures are the same. The camera application may select a picture as the preselected image according to preset rules. Alternatively, the preset rule may be a manner of specifying a picture, for example, in the two-shot mode, a specified picture (e.g., a lower picture) is selected as the preselected image. Alternatively, the preset rule may be to select a picture with higher brightness as the preselected image. The above selection is merely an illustrative example, and the present application is not limited thereto.

And selecting the picture corresponding to the appointed lens as a preselected image. For example, a picture captured by a front camera may be selected as the preselected image. The method can be specifically set according to actual requirements, and is not limited in the application.

S108, selecting the picture of the appointed lens.

And S109, selecting the picture according to a preset rule.

S110, selecting a large screen.

For example, in a picture-in-picture capture mode, a camera application may select a large picture in picture-in-picture as the preselected image. Of course, in other embodiments, a small picture in a picture-in-picture may be selected as the preselected image, and the application is not limited thereto.

As described above, when selecting an image frame as a thumbnail or a cover of an album, the first image frame of the video may be selected, or the image frame with the highest picture quality among the first 20 image frames may be selected. In conjunction with the flowchart shown in fig. 8a, if the image frame as the preselected image is an image frame in the first 20 image frames, in one example, the camera application may first determine the image frame as the target picture based on the first frame of the video. For example, taking a picture-in-picture scene as an example, the camera application may perform S102 and S110 based on the first image frame. After the camera application determines that a large picture needs to be selected as a preselected image, the camera application may select an image frame of the best picture quality from the first 20 image frames and use the large picture of the image frame as the preselected image. In another example, the camera application may select an image frame with the best quality from the first 20 image frames, and then perform a picture selection process based on the selected image frame, i.e. the process in fig. 8 a. The sequence of selecting the image frame with the optimal quality and selecting the image by the mobile phone is not limited.

For example, after the camera application acquires the preselected image, the selected image frame (which may be the first image frame, or an image frame with the best picture quality from the first 20 image frames) and the selected preselected image selection may be output to the gallery application. The gallery application may perform a photo album cover or thumbnail generation process based on the selection results (including the image frames and the pre-selected images) input by the camera application. In the embodiment of the present application, only an embodiment in which a gallery application generates a thumbnail and an album cover will be described. In other embodiments, the gallery application may also be used for storing videos or images to designated areas and the like. This application is not repeated.

Fig. 8b is a schematic diagram of an exemplary generation thumbnail. Note that, fig. 8b illustrates only the flow of generating thumbnails, and a mobile phone may also generate an album cover based on the flow in fig. 8 b. Referring to fig. 8b, the method specifically includes:

s201, thumbnail generation is started.

For example, after acquiring the image frame and the pre-selected image selected by the camera application, the gallery application starts to execute the process of generating the cover page and/or the thumbnail. Namely, S202 to S207 are executed.

S202, whether the sizes of the image frame and the thumbnail are close or not is detected.

Illustratively, as described above, the proportion of the album cover or thumbnail generated by the gallery application is a preset proportion, for example, the preset proportion (long: high) of thumbnail is 1. In the embodiment of the present application, only the three preset ratios are taken as an example for description, in other embodiments, the preset ratio between the thumbnail and the album cover may be set according to actual requirements, and the present application is not limited.

For example, taking the preset ratio of the thumbnail image as 1. For example, in order to distinguish the selected image frame from other image frames in the camera application, the selected image frame is referred to as a target image frame in the following embodiments.

For example, the gallery application may compare the target image frame to the thumbnail to determine whether the target image frame and the thumbnail are similar in size. The specific manner of comparison will be illustrated in the following examples.

In one example, if the gallery application detects that the target image frame is similar in size to the thumbnail, S207 is performed.

In another example, if the gallery application detects that the target image frame and the thumbnail are not similar in size, S203 is performed.

And S203, detecting a mode.

For example, the gallery application may detect a current shooting mode. S102 may be referred to specifically, and details thereof are not repeated herein.

In one example, if the gallery application detects that the shooting mode is the multi-view mode, S204 is performed.

In another example, if the gallery application detects that the shooting mode is the picture-in-picture mode, S205 is performed.

And S204, displaying the multi-scene identification by taking the preselected image as a thumbnail.

For example, in the case that the gallery application detects that the target image frame is not similar to the thumbnail in size and the current shooting mode is the multi-view shooting mode, the gallery application may generate a thumbnail based on the pre-selected image, and the generated thumbnail includes the multi-view identifier thereon. For example, the multi-view identifier may be used to identify that the video corresponding to the thumbnail is a video captured in a multi-view capturing mode.

S205, whether the small image is cut or not is detected.

For example, as shown in fig. 4b, a video photographed in a picture-in-picture photographing mode may include a large window and a small window. In the embodiment of the present application, a picture displayed in a large window is referred to as a large picture or a large image, and a picture displayed in a small window is referred to as a small picture, a small image, or a picture-in-picture image. Under the condition that the gallery application detects that the target image frame is not close to the thumbnail and the shooting mode is the picture-in-picture mode, the gallery application can detect whether the small image is cut or not based on the preset proportion of the thumbnail. Where "thumbnail is cropped" is optionally that when a thumbnail or album cover is generated based on the image frame, a partial image of the thumbnail will be cropped so that the thumbnail is incomplete when displayed in the thumbnail or album cover, such as shown in fig. 7e or 7 f.

In one example, if the gallery application detects that the thumbnail will not be cropped, then S207 is performed.

In another example, if the gallery application detects that a small image is to be cropped, then S206 is performed.

And S206, taking the preselected image as a thumbnail and displaying the picture-in-picture mark.

For example, in the case where the gallery application detects that the target image frame is not of a similar size to the thumbnail, the capture mode is a picture-in-picture capture mode, and the thumbnail is to be cropped, the gallery application may generate the thumbnail based on the preselected image. And displaying the picture-in-picture identification on the generated thumbnail. Illustratively, the picture-in-picture identifier is used to identify the video corresponding to the thumbnail as a video captured in a picture-in-picture capture mode.

S207, the preselected image is taken as a thumbnail.

For example, if the gallery application detects that the target image frame is a similar size to the thumbnail, or the gallery application detects that the thumbnail is not to be cropped, the gallery application may generate the thumbnail based on the target image frame. Illustratively, if the user clicks the thumbnail, the mobile phone responds to the received user operation and displays the video corresponding to the thumbnail. For example, the interface may be a preview interface that displays the video, or the interface may directly play the video.

In the embodiment of the present application, a gallery application and a camera application are described as an example. In other embodiments, the flows in fig. 8a and 8b may also be executed by one or more other modules of the application layer, which is not limited in this application.

The flow in fig. 8a and 8b is described in detail below with several embodiments. Fig. 10 is a schematic diagram of an exemplary dual-view shooting scene. Referring to fig. 10, a preview interface 1001 illustratively includes, but is not limited to, a capture control 1002, a display window 1003, and a display window 1004. In this embodiment, an example will be described in which the display window 1003 displays an image captured by a rear camera and the display window 1004 displays an image captured by a front camera. It should be noted that the cameras called in each scene in the embodiment of the present application are only schematic examples, and the present application is not limited thereto.

Continuing with fig. 10, the user can click on a capture control 1002, as an example. And the mobile phone starts recording in response to the received user operation.

Illustratively, as described in S102 of fig. 8a, after the mobile phone starts recording, the camera application detects the shooting mode. For example, the camera application detects that the current shooting mode is a dual shot mode. Then, the camera application may select an image frame 1101 with the best picture quality from the first 20 image frames of the video as the target image frame described above. Next, the camera application may detect the number of people in the image frame 1101, i.e. perform S113 in fig. 8 a.

Referring to fig. 11, an image frame 1101 illustratively includes an image 1102 and an image 1103. The image 1102 is an image acquired by a rear camera, and the image 1103 is an image acquired by a front camera. The cell phone detects the image frame 1101 and determines that two persons are included in the image frame 1101, namely a person in the image 1102 and a person in the image 1103. After the camera application detects that two human images are included in the image frame 1101 as described in S103 in fig. 8a, the camera application may further detect whether the owner is included in the two human images.

Continuing to refer to fig. 11, an example is shown in which the person in the image 1103 is the owner. After the camera application determines that the person in the image 1103 is the owner, the camera application selects an image including the owner as the preselected image, i.e., selects the image 1103 as the preselected image 1104.

Illustratively, the camera application may output the selected results, i.e., the image frame 1101 and the preselected image 1104, to the gallery application. The gallery application may generate a thumbnail or album cover based on the image frame 1101 or the preselected image 1104 in accordance with the flow shown in FIG. 8 b.

As described above, the thumbnail has a preset ratio with the album cover, and fig. 12 is a schematic view of the preset ratio of the thumbnail or the album cover, which is exemplarily shown. Referring to fig. 12, exemplary preset scales (length: height) for thumbnails or album covers may include, but are not limited to: 1, 3. In the embodiment of the present application, taking the preset proportion of the thumbnail as 1, the preset proportion of the album cover includes 3.

Illustratively, the gallery application performs S202 in fig. 8b, i.e., determines whether the image frame 1101 is similar in size to a thumbnail or album cover. For example, fig. 13a is a schematic diagram illustrating an exemplary detection of whether an image frame is close to a thumbnail in size. Referring to fig. 13a, the gallery application illustratively compares a crop box 1301 corresponding to the thumbnail to an image frame 1101. Illustratively, the crop box 1301 is in the same preset proportion as the thumbnail, namely 1. In the embodiment of the present application, the gallery application aligns the geometric center of the crop box 1301 with the geometric center of the image frame 1101, and reduces or enlarges the crop box 1301 in an equal ratio according to a preset ratio (i.e., 1). For example, as shown in fig. 13a, the left and right borders of the crop box 1301 overlap the left and right borders of the image frame 1101, and the top and bottom borders of the crop box 1301 are within the image frame 1101. It should be noted that the detection manner shown in fig. 13a is only an illustrative example, and in other embodiments, the geometric center of the crop box 1301 may not be aligned with the center of the image frame 1101, for example, the gallery application may align the upper border of the crop box 1301 with the upper border of the image frame 1101, and scale up or scale down the crop box 1301 such that the four borders of the crop box 1301 do not exceed the four borders of the image frame 1101. The manner of comparing the image frame with the crop box in the embodiment of the present application is only an illustrative example, and the present application is not limited thereto. Hereinafter, the same, and description will not be repeated.

The gallery application may determine whether the image frame is similar in size to the thumbnail based on the overlapping area of the crop box 1301 and the image frame 1101. Illustratively, in the embodiment of the present application, the gallery application may set a similarity threshold, for example, the similarity threshold may be set to 80%. For example, if the ratio of the overlapping area of the crop box 1301 and the image frame 1101 to the area of the image frame 1101 is greater than or equal to 80%, it may be determined that the image frame 1101 and the thumbnail are similar in size. If the ratio of the overlapping area of the crop frame 1301 and the image frame 1101 to the area of the image frame 1101 is less than 80%, it may be determined that the image frame 1101 and the thumbnail are not similar in size.

Referring to fig. 13a, for example, in the embodiment of the present application, a ratio of an overlapping area of the image frame 1101 and the crop box 1301 to an area of the image frame 1101 is less than 80%, that is, sizes of the image frame 1101 and the thumbnail are not similar to each other.

For example, after the gallery application determines that the image frame 1101 is not similar in size to the thumbnail, S203 in fig. 8b may be executed. For example, the gallery application may detect that the current capture scene is in a dual view capture mode, and the gallery application may generate a thumbnail based on the preselected image 1104. Fig. 13b is a schematic diagram of an exemplary generation thumbnail. Referring to fig. 13b, the gallery application may crop the preselected image 1104 based on the thumbnail's corresponding crop frame 1301, for example. For example, the gallery application may align the geometric center of the crop box 1301 with the geometric center of the preselected image 1104 and zoom the crop box 1301 up or down to the four borders of the crop box 1301 not exceeding the four borders of the preselected image 1104.

Continuing with FIG. 13b, the gallery application crops the preselected image 1104 based on the crop box 1301 to obtain a thumbnail 1302, as an example. The gallery application displays a multi-view logo 1303 on the thumbnail 1302, indicating that the video corresponding to the thumbnail 1302 was captured in a multi-view capture mode. It should be noted that the pattern, size and position of the multi-scene mark 1304 in the embodiments of the present application are only schematic examples. In other embodiments, the setting may be according to actual requirements, and the present application is not limited.

Continuing with fig. 13b, for example, if the handset is responding to the received user action, the gallery application is launched. A thumbnail 1305 may be displayed in the gallery interface 1304, and a multi-scene identification is displayed on the thumbnail 1305. Optionally, the thumbnail 1305 may be an optional thumbnail library application, and the thumbnail 1302 may be scaled down according to a predetermined ratio, for example, 50% (which may be set according to actual requirements, and is not limited in this application).

Fig. 14a to 14b are schematic views of an exemplary generated album cover. Referring to FIG. 14a, the gallery application may illustratively compare a crop box 1401 corresponding to an album cover with an image frame 1101 to determine whether the image frame is of a similar size to the album cover. Alternatively, the ratio (length: height) of the crop box 1501 is 3. The specific details can be described with reference to fig. 13a, and are not repeated herein.

Illustratively, the image frame 1101 is not similar to the size of the album cover. Then the gallery application generates an album cover based on the preselected image 1104.

Referring to FIG. 14b, the gallery application may illustratively crop the preselected image 1104 based on the crop box 1401. Illustratively, the gallery application aligns the geometric center of the crop box 1401 with the geometric center of the preselected image 1104 and zooms or zooms out the crop box 1401 to the extent that the four borders of the crop box 1401 do not extend beyond the four borders of the preselected image 1104. For example, as shown in fig. 14b, the top and bottom borders of the crop box 1401 overlap the top and bottom borders of the preselected image 1104, and the left and right borders of the crop box 1401 are within the preselected image 1104. The gallery application gets a cropped album cover 1402. The gallery application displays a multi-view logo 1403 on the album cover 1402.

Continuing with fig. 14b, for example, if the handset is responding to the received user action, the gallery application is launched. An album cover 1402 may be displayed in the album interface 1404, and a multi-view logo may be displayed on the album cover 1402. Alternatively, the album cover 1402 can be scaled down by a predetermined ratio, for example, 50% (which can be set according to actual requirements, but is not limited in this application), and then displayed at a designated position of the album interface 1404.

Fig. 15a to 15b are schematic views of an exemplary generated album cover. Referring to FIG. 15a, for example, the gallery application may compare a crop box 1501 corresponding to the album cover with the image frame 1101 to determine whether the image frame is of a similar size to the album cover. Alternatively, the ratio (length: height) of the crop box 1501 is 4. The specific details can be described with reference to fig. 13a, and are not repeated herein.

Referring to FIG. 15b, the gallery application may illustratively crop the preselected image 1104 based on the crop box 1501. Illustratively, the gallery application aligns the geometric center of the crop box 1501 with the geometric center of the preselected image 1104 and zooms in or zooms out the crop box 1501 to the extent that the four borders of the crop box 1501 do not exceed the four borders of the preselected image 1104. For example, as shown in fig. 15b, the left and right borders of the crop box 1501 overlap the left and right borders of the preselected image 1104, and the top and bottom borders of the crop box 1501 are within the preselected image 1104. The gallery application gets a cropped album cover 1502. The gallery application displays a multi-view logo 1503 on the album cover 1502.

Continuing with fig. 15b, for example, if the handset is responding to the received user action, the gallery application is launched. An album cover 1502 may be displayed in the album interface 1504 and a multi-view logo may be displayed on the album cover 1502. Alternatively, the album cover 1502 may be scaled down by a predetermined ratio, for example, 50% (which may be set according to actual requirements, but is not limited in this application), and then displayed at a designated position of the album interface 1504.

In one possible implementation, as described above, the thumbnail of each image or video displayed by the gallery interface may be displayed in the original scale of the image or video. As shown in fig. 16, the mobile phone displays a gallery interface 1601 in response to a received user operation. A thumbnail 1602 may be displayed on gallery interface 1601. Wherein the thumbnail 1602 is generated for the gallery application based on the image frame 1101. For example, the gallery application reduces the image frame 1101 by a preset scale (e.g., 50%) and displays the reduced image frame at a designated position on the gallery interface 1601.

Fig. 17 is a schematic diagram of an exemplary dual-view shooting scene. Referring to FIG. 17, a preview interface 1701 illustratively includes, but is not limited to, a capture control 1702, a display window 1703, and a display window 1704. In this embodiment, the image captured by the rear camera displayed in the display window 1703 and the image captured by the front camera displayed in the display window 1704 will be described as an example. It should be noted that the cameras called in each scene in the embodiment of the present application are only schematic examples, and the present application is not limited thereto.

Continuing with FIG. 17, the user can click on a capture control 1702, for example. And the mobile phone starts recording in response to the received user operation.

Referring to fig. 18, after the mobile phone starts recording, as described in S102 of fig. 8a, the camera application detects the shooting mode. For example, the camera application detects that the current shooting mode is a double shot mode. Then, after the camera application determines that the shooting mode is the dual shot mode, the camera application may select the image frame 1801 with the best picture quality from the first 20 image frames of the video as the target image frame described above. The camera application may detect the number of people in the image frame 1801, i.e., perform S103 in fig. 8 a.

Continuing to refer to fig. 18, an exemplary image frame 1801 includes an image 1802 and an image 1803. The image 1802 is an image collected by a rear camera, and the image 1803 is an image collected by a front camera. The cell phone detects the image frame 1801 and determines that a person is included in the image frame 1801, i.e., in the image 1803. After the camera application detects that an image of a person is included in the image frame 1801, as described in reference to S103 of fig. 8a, the camera application may select the image including the person, i.e., the image 1803, as the preselected image 1804.

Illustratively, the camera application may output the results of the selection, i.e., the preselected image 1804 and the target image frame 1801, to the gallery application. The gallery application may perform the flow in fig. 8b based on the preselected image 1804 and the target image frame 1801. The specific details can be described with reference to fig. 10 to 15b, and are not described herein again.

Fig. 19 is a schematic view of another exemplary dual-view shooting scene. Referring to fig. 19, the preview interface 1901 illustratively includes, but is not limited to, a capture control 1902, a display window 1903, and a display window 1904. In this embodiment, an example in which both the display window 1903 and the display window 1904 display images captured by a rear camera is taken is described. The display window 1903 shows an image acquired by the wide-angle camera, and the display window 1904 shows an image acquired at 2 times of the focal length. It should be noted that the cameras called in each scene in the embodiment of the present application are only schematic examples, and the present application is not limited thereto.

Continuing with FIG. 19, the user can click on a capture control 1902, as an example. And the mobile phone starts recording in response to the received user operation.

Referring to fig. 20, after the mobile phone starts recording, the camera application may select the image frame 2001 with the best picture quality from the first 20 image frames of the video as the target image frame described above. As described in S102 in fig. 8a, the camera application detects the shooting mode, for example. For example, the camera application detects that the current shooting mode is a double shot mode. Next, after the camera application determines that the photographing mode is the dual view photographing mode, the camera application may detect the number of persons in the image frame 2001, i.e., perform S103 in fig. 8 a.

Continuing to refer to fig. 20, image frame 2001 illustratively includes image 2002 and image 2003. Illustratively, the image 2002 is an image acquired by a rear camera with 800 ten thousand pixels at a focal length of 2 times, and the image 2003 is an image acquired by a wide-angle camera with 1600 ten thousand pixels. The mobile phone detects the image frame 2001 and determines that two persons are included in the image frame 2001, that is, the person in the image 2002 and the person in the image 2003. After the camera application detects that two human images are included in the image frame 2001, as described in S103 of fig. 8a, the camera application further detects whether the owner is included. Illustratively, the camera application detects that the owner is not included in the two people. Then the camera application executes as per S107 in fig. 8a, i.e. the camera application detects whether the parameters of the different lenses are the same. In this embodiment, the camera application detects that the lens parameters are different (i.e. one is a rear camera with 800 ten thousand pixels and one is a wide-angle camera with 1600 ten thousand pixels). Accordingly, the camera application performs S108 in fig. 8a, i.e., the camera application selects a screen of the specified lens as a preset image. For example, in the present embodiment, the camera application may select an image captured by the wide-angle camera as the preset image, that is, the camera application selects the image 2003 as the preset image 2004.

Illustratively, the camera application may output the selected results, i.e., the pre-selected image 2004 and the target image frame 2001, to the gallery application. The gallery application may perform the flow in fig. 8b based on the pre-selected image 2004 and the target image frame 2001. The specific details can be described with reference to fig. 10 to 15b, and are not described herein again.

Fig. 21 is a schematic view of another exemplary dual-scene shooting scene. Referring to fig. 21, the preview interface 2101 illustratively includes, but is not limited to, a capture control 2102, a display window 2103, and a display window 2104. In this embodiment, an example in which both the display window 2103 and the display window 2104 display images captured by the rear camera is taken as an example will be described. Illustratively, the images displayed by the display window 2103 and the display window 2104 are images acquired by a rear camera with 800 ten thousand pixels at 1-time focal length. It should be noted that the cameras called in each scene in the embodiment of the present application are only schematic examples, and the present application is not limited thereto.

Continuing with fig. 21, the user can click on a capture control 2102, for example. And the mobile phone starts recording in response to the received user operation.

Illustratively, as described in S102 of fig. 8a, after the mobile phone starts recording, the camera application detects the shooting mode. For example, the camera application detects that the current shooting mode is a dual shot mode. Next, referring to fig. 22, after determining that the shooting mode is the double-shot shooting mode, the camera application may select an image frame 2201 with the best picture quality from the first 22 image frames of the video as the target image frame. The camera application detects the number of people in the image frame 2201, i.e. performs S103 in fig. 8 a.

Continuing to refer to fig. 22, image frame 2201 illustratively includes an image 2202 and an image 2203. The gallery application detects image frame 2201 and determines that no person is included in image frame 2201. After the camera application detects that the image frame 2201 does not include the image of the person as described in S103 in fig. 8a, the camera application performs as in S107 in fig. 8a, that is, the camera application detects whether the parameters of different lenses are the same. In this embodiment, the camera application detects that the lens parameters are the same, that is, the camera application is shooting with a rear camera with 800 ten thousand pixels. Accordingly, the camera application performs S109 in fig. 8a, i.e., the camera application selects the preset image according to the preset rule. In the embodiment of the present application, a preset rule is taken as an example to select the lower image. Illustratively, the camera application selects the lower image, image 2203, as the preset image 2204.

Illustratively, the camera application may output the results of the selection, i.e., the pre-selected image 2204 and the target image frame 2201, to the gallery application. The gallery application may perform the flow in fig. 8b based on the preselected image 2204 and the target image frame 2201. The specific details can be described with reference to fig. 10 to 15b, and are not described herein again.

Fig. 23a is a schematic diagram of an exemplary multi-shot scene. Referring to fig. 23a, the preview interface 2301 includes, but is not limited to, a display window 2302, a display window 2303, a display window 2304 and a shooting control 2305. In this embodiment, the display window 2302 displays an image captured by a wide-angle camera with 1600 ten thousand pixels, the display window 2303 displays an image captured by a front camera, and the display window 2304 displays an image captured by a rear camera with 800 ten thousand pixels at 2 times of focal length. It should be noted that the cameras called in each scene in the embodiment of the present application are only schematic examples, and the present application is not limited thereto.

Continuing with fig. 23a, the user can click on a capture control 2305, for example. And the mobile phone starts recording in response to the received user operation.

Illustratively, after the handset starts recording, the camera application detects the shooting mode as described in S102 in fig. 8 a. For example, the camera application detects that the current shooting mode is a double shot mode. Referring to fig. 23b, after the camera application determines that the shooting mode is the double-shot shooting mode, the camera application may select an image frame 2306 with the best picture quality from the first 20 image frames of the video as the target image frame described above. The camera application may detect the number of people in the image frame 2306, i.e. perform S103 in fig. 8 a.

Continuing to refer to fig. 23b, image frame 2306 illustratively includes image 2307, image 2308, and image 2309. Illustratively, the gallery application detects the image frame 2306 and determines that three people are included in the image frame 2306, namely, a person in the image 2307, a person in the image 2308, and a person in the image 2309. After the camera application detects that three person images are included in the image frame 2306, the camera application further detects whether the owner is included, as described in S103 in fig. 8 a. Illustratively, the camera application detects that the person in the image 2308 is an owner. The camera application is executed as S106 in fig. 8a, i.e., the camera application may select the image 2308 including the main image as the preset image 2310.

Referring to FIG. 24a, the gallery application compares a thumbnail corresponding crop box 2401 to an image frame 2306, for example. Illustratively, the crop box 2401 is the same as the thumbnail in a preset scale, i.e., 1. In the embodiment of the present application, the gallery application aligns the geometric center of the crop box 2401 with the geometric center of the image frame 2306, and scales down or up the crop box 2401 by a preset ratio (i.e., 1). For example, as shown in FIG. 24a, the four borders of crop box 2401 overlap the four borders of image frame 2306.

With continued reference to fig. 24a, in the embodiment of the present application, the ratio of the overlapping area of the image frame 2306 and the crop box 2401 to the area of the image frame 2306 is 100%, that is, greater than the similarity threshold (80%), that is, the image frame 2306 is similar to the thumbnail in size.

Illustratively, after the gallery application determines that the image frame 2306 is similar in size to a thumbnail, S207 in fig. 8b may be performed, i.e., a thumbnail is generated based on the target image frame. Referring to fig. 24b, the cell phone may illustratively launch a gallery application in response to a received user action. A thumbnail 2403 may be displayed in gallery interface 2402. Illustratively, the thumbnail 2403 is generated by the gallery application based on the image frame 2306, for example, the gallery application displays the image frame 2403 at a designated position of the gallery interface 2402 after scaling down the image frame by a preset scale, for example, by 50%.

It should be noted that, for the image captured in the multi-view shooting mode shown in fig. 23a, the step of generating the album cover with the preset ratio of 3.

Fig. 25a is a diagram of an exemplary picture-in-picture capture scene. Referring to fig. 25a, the preview interface 2501 illustratively includes, but is not limited to, a large display window 2502 (which may also be referred to as a large window), a small display window 2503 (which may also be referred to as a small window, a picture-in-picture window, or a floating window), and a capture control 2504. It should be noted that the mobile phone may change the position and size of the small display window 2503 in response to the received user operation (e.g., dragging the small display window 2503). Alternatively, the small display window 2503 is suspended over the large display window 2502, and it can be understood that the small display window 2503 is in the large display window 2502, and the size of the small display window 2503 is smaller than or equal to the size of the large display window 2503. Accordingly, a small picture (or a small image) in the small display window 2503 in the generated image frame is among large pictures (or large images) in the large display window 2502. Optionally, the adjustable maximum size of the small display window 2503 is smaller than the size of the large display window 2502. It should be noted that, in the embodiment of the present application, only the example that the picture-in-picture mode includes a small display window is taken as an example for description. In other embodiments, the pip mode may also include two or more small display windows, which are all suspended above the large display window, during the shooting process. Accordingly, a plurality of small images are generated on top of the large image in the image frame.

Illustratively, the large display window 2502 displays images captured by a rear camera, and the small display window 2503 displays images captured by a front camera. It should be noted that the cameras called in each scene in the embodiment of the present application are only illustrative examples, and the present application is not limited thereto.

Continuing with fig. 25a, for example, the user can click on a capture control 2504. And the mobile phone starts recording in response to the received user operation.

After the mobile phone starts recording, as described in S102 in fig. 8a, the camera application detects the shooting mode. For example, the camera application detects that the current photography mode is a picture-in-picture photography mode. Referring to fig. 25b, after the camera application determines that the shooting mode is the picture-in-picture shooting mode, the camera application can select an image frame 2505 with the best picture quality from the first 20 image frames of the video as the target image frame. Illustratively, the image frame 2505 includes an image 2506 and an image 2507. The image 2506 may be referred to as a large image, i.e., an image in the large display window 2502. The image 2507 may be referred to as a small image or a picture-in-picture image, i.e., an image in the small display window 2503. Accordingly, the camera application performs S110 in fig. 8a, i.e., the camera application selects the large image (image 2506) as the preset image 2508.

Illustratively, the camera application may output the results of the selection, i.e., the image frame 2505 and the pre-selected image 2508, to the gallery application. The gallery application may generate a thumbnail or album cover based on the image frame 2505 or the pre-selected image 2508 according to the flow shown in FIG. 8 b.
