Fig. 1 is a flowchart illustrating a file generation method according to an exemplary embodiment, where the file generation method is used in a mobile device, as shown in fig. 1, and includes the following steps:

in step 101, a shooting instruction for shooting by a first camera and a second camera on the mobile device is started while the user input is detected.

In step 102, according to the shooting instruction, the first camera is simultaneously controlled to shoot horizontal screen image information of the same scene, and the second camera shoots vertical screen image information of the same scene, wherein the picture centers of the horizontal screen image information and the vertical screen image information are overlapped;

in step 103, simultaneously displaying the horizontal screen image information and the vertical screen image information to the user;

in step 104, after the end of shooting is detected, a horizontal screen file is generated according to the displayed horizontal screen image file information, and a vertical screen file is generated according to the vertical screen image information.

The file generation method disclosed by the disclosure can be applied to a terminal, a server and the like, and is not limited herein, and the terminal implementation device of the file generation method can be an electronic device such as a smart phone, a notebook computer and a tablet computer, and is not limited herein.

The following describes in detail specific implementation steps of a file generation method provided in the embodiment of the present disclosure with reference to fig. 1.

Firstly, executing step 101, detecting a shooting instruction input by a user, wherein the shooting instruction is an instruction for starting a first camera and a second camera on mobile equipment to shoot simultaneously;

in this embodiment, the mobile device at least includes a first camera and a second camera, where the first camera may be one of a plurality of rear cameras and is used to shoot horizontal screen image information, and the second camera may also be another one of the plurality of rear cameras and is used to shoot vertical screen image information, or vice versa, and this embodiment is not limited. It should be noted that, the front camera or the rear camera on the mobile device, except for the first camera and the second camera currently used, includes the remaining cameras, and a part of the remaining cameras are alternative cameras of the original proportion of the image shot by the first camera; and the other part of the rest cameras are alternative cameras with original proportion of the images shot by the second camera. Of course, the first camera and the second camera may also be cameras at other positions on the mobile device, and this embodiment is not limited.

In this embodiment, the photosensitive elements (CMOS) of the first camera and the second camera on the mobile device may be the same or different, and in a normal case, it is default that the photosensitive elements (CMOS) of the first camera and the second camera are the same, and one horizontal camera and one vertical camera are placed (that is, the original proportion of the image information output by the two cameras is the same as the required image proportion), so as to ensure the consistency of the picture centers of the horizontal screen image information collected by the first camera and the vertical screen image information collected by the second camera (that is, the picture centers coincide), and if different, the centers of the pictures of the horizontal screen image information collected by the first camera and the vertical screen image information collected by the second camera need to be firstly adjusted to be consistent.

In this embodiment, a user may start a unidirectional shooting function or a bidirectional shooting function of a shooting application as needed, and if the user starts the bidirectional shooting function, that is, the mobile device detects that a shooting instruction input by the user is a bidirectional shooting instruction, that is, an instruction for simultaneously starting the first camera and the second camera to shoot; of course, when the user starts a shooting instruction of the shooting application, a plurality of shooting selection modes are displayed to the user, such as starting the first camera, starting the second camera, or simultaneously starting the first camera and the second camera, and the like, and of course, more cameras can be started, and the like, which is not limited in this embodiment.

In this embodiment, it is detected that the user simultaneously starts the first camera and the second camera on the mobile device to perform a shooting instruction.

Secondly, executing a step 102, according to the shooting instruction, simultaneously controlling the first camera to shoot horizontal screen image information of the same scene and the second camera to shoot vertical screen image information of the same scene, wherein the picture centers of the horizontal screen image information and the vertical screen image information are overlapped;

in this step, the mobile device simultaneously starts the first camera and the second camera for shooting according to the shooting instruction, that is, simultaneously starts the shooting module of the first camera to collect the horizontal screen image information of the same scene, and starts the shooting module of the second camera to collect the vertical screen image information of the same scene. That is to say, the imaging system of the first camera and the imaging system of the second camera are independent imaging systems respectively, and the two imaging systems can shoot the same scene at the same time to obtain the horizontal screen image information and the vertical screen image information of the scene.

Thirdly, executing step 103, and simultaneously displaying the horizontal screen image information and the vertical screen image information to the user;

in this step, after the mobile device obtains the horizontal screen image information and the vertical screen image information at the same time, the horizontal screen image information shot by the first camera and the vertical screen image information shot by the second camera can be simultaneously displayed on the display screen of the mobile device. That is to say, in this embodiment, the display screen of the mobile device is divided into a horizontal screen image display area and a vertical screen image display area, where the horizontal screen image display area is used to display the shot horizontal screen image information, and the vertical screen image display area is used to display the shot horizontal screen image information, that is, in this embodiment, only the horizontal screen image information and the vertical screen image information which are simultaneously started to be shot in two directions are displayed on the same screen in a split manner, for example, the upper side of the screen is used as the horizontal screen image display area, and the lower side is used as the vertical screen image display area, as shown in fig. 2 in particular, fig. 2 is a schematic diagram of the screen provided by this disclosure for simultaneously displaying the horizontal screen image area and the vertical screen image area, fig. 2 is only an example, and in practical application, this is not limited thereto, and other manners may also be used, such as the upper side of the screen is used as the vertical screen image display area, the lower side may be a horizontal screen image display area or the like, and may be left and right. Of course, if the user selects the shooting mode of the shooting application to be shooting through only one camera, the image information shot by the one camera may be displayed on the full screen of the display screen of the mobile device, and the image information may be horizontal screen image information or vertical screen image information, which is not limited in this embodiment.

And finally, executing step 104, when the shooting end is detected, generating a horizontal screen file according to the displayed horizontal screen image file information, and generating a vertical screen file according to the vertical screen image information.

In the step, when the terminal detects that the shooting is finished, a horizontal screen file is generated according to the displayed horizontal screen image file information, and a vertical screen file is generated according to the vertical screen image information. That is to say, when the shooting is finished, the corresponding horizontal screen file and the vertical screen file are respectively generated according to the shot horizontal screen image information and the shot vertical screen image, and the horizontal screen file and the vertical screen file are saved.

According to the method and the device, when a shooting instruction that a first camera and a second camera on the mobile equipment shoot is started while user input is detected, the first camera is controlled to shoot transverse screen image information of the same scene and the second camera shoots vertical screen image information of the same scene, the transverse screen image information and the vertical screen image information are displayed for the user at the same time, when shooting is detected to be finished, a transverse screen file is generated according to the displayed transverse screen image file information, and a vertical screen file is generated according to the vertical screen image information. That is to say, in the present disclosure, by using the characteristics of the multiple cameras on the mobile device, two cameras can be controlled to simultaneously shoot the horizontal screen image and the vertical screen image of the same scene, that is, once shooting is performed, the horizontal screen image information and the vertical screen image information of the scene can be simultaneously obtained (i.e., image information with different proportions is obtained), so that not only is the shooting efficiency improved, but also the shooting time of the user is saved.

FIG. 3 is another flow chart illustrating a file generation method, as shown in FIG. 3, for use in a mobile device, according to an exemplary embodiment, the method comprising the steps of:

step 301: detecting a shooting instruction input by a user, wherein the shooting instruction is an instruction for starting a first camera and a second camera on the mobile equipment to shoot simultaneously;

step 302: according to the shooting instruction, the first camera is controlled to shoot transverse screen image information of the same scene, and the second camera is controlled to shoot vertical screen image information of the same scene, wherein the image centers of the transverse screen image information and the vertical screen image information are overlapped;

in this embodiment, the implementation processes of step 301 and step 302 are the same as those of step 101 and step 102, and are specifically described above, and are not described again here.

Step 303: judging whether the horizontal screen image information and the vertical screen image information both meet the horizontal screen proportion and the vertical screen proportion of a preset file; if yes, go to step 304 and step 307; if not, go to step 305;

in this step, because the screen proportion of different platforms is different, for example, the mobile phone screen proportion is different from the computer screen proportion, the proportion of horizontal and vertical screens of the full-screen displayed image or video on different platforms is different, and based on this, the screen proportion of the horizontal screen image information and the vertical screen image information shot by the user needs to be judged, so that the shot image or video can be displayed on different platforms in full-screen.

The method comprises the steps that the horizontal screen proportion and the vertical screen proportion of a preset file are predetermined, and the determination mode is that the preset values of the horizontal screen proportion and the vertical screen proportion of different social platforms (such as a mobile phone platform, a computer platform and the like) to an uploaded file are obtained; and then according to the preset value, setting the horizontal screen proportion and the vertical screen proportion of the generated file, for example, the video on the short video platform of the mobile phone is generally vertical screen, the length of the uploaded video is required to be larger than the width, and the preset value of the proportion of the width to the length can be 3:4, 9:16, etc.; for another example, a video on a computer platform is generally a horizontal screen, and the width of the uploaded video is required to be greater than the length, for example, the preset value of the ratio of the width to the length may be: 4:3,16:9.

In this step, the terminal judges whether the horizontal screen image information meets the horizontal screen proportion of a preset file, and judges whether the vertical screen image information meets the vertical screen proportion of the preset file, if so, the step 304 is executed; otherwise, step 305 is performed as long as one is not satisfied.

Step 304: simultaneously displaying the horizontal screen image information and the vertical screen image information to the user;

the step is the same as the implementation process of step 103, and is described in detail above, and is not described herein again.

Step 305: clipping the horizontal screen image information and/or the vertical screen image information which are not satisfied;

in the step, the mobile device cuts the unsatisfied transverse screen image information and/or vertical screen image information, specifically, the mobile device can control the image data acquisition module of the first camera to cut the shot transverse screen image information (namely the original transverse screen picture) according to the transverse screen proportion of a preset file, or, controlling an image data acquisition module of the second camera to cut the shot vertical screen image information (namely the original vertical screen picture) according to the vertical screen proportion of the preset file, or simultaneously controlling the image data acquisition module of the first camera and the image data acquisition module of the second camera to respectively cut the shot transverse screen image information and vertical screen image information according to the transverse screen proportion and the vertical screen proportion of a preset file, therefore, the horizontal screen image information meeting the horizontal screen proportion requirement of the preset file and the vertical screen image information meeting the vertical screen proportion requirement of the preset file are obtained.

The horizontal screen image information and the vertical screen image information before and after cropping are shown in fig. 4A and 4B, wherein fig. 4A is a schematic scale diagram of the horizontal screen image information before and after cropping according to an exemplary embodiment, and fig. 4B is a schematic scale diagram of the vertical screen image information before and after cropping according to an exemplary embodiment.

In fig. 4A, the ratio of the landscape image information (i.e., the original frame) before clipping is 4:3, clipping is performed according to the preset value of the preset landscape ratio, the ratio of the landscape image information after clipping is 16:9, and the landscape image information after clipping is specifically shown by the diagonal line portion in fig. 4A.

Similarly, in fig. 4B, the ratio of the vertical screen image information (i.e., the original image frame) before clipping is 3:4, clipping is performed according to the preset value of the preset horizontal screen ratio, the ratio of the clipped vertical screen image information is 9:16, and the clipped horizontal screen image information is specifically shown by the diagonal line segment in fig. 4B.

Step 306: displaying the cut horizontal screen image information and vertical screen image information to the user at the same time;

in this step, the process shown in step 103 is the same as or similar to that shown in step 103, and is described in detail above, and is not described herein again.

Step 307: and when the shooting is detected to be finished, generating a horizontal screen file according to the displayed horizontal screen image file information, and generating a vertical screen file according to the vertical screen image information.

The step is the same as the implementation process of step 104, and is described in detail above, and is not described herein again.

According to the method and the device, whether the horizontal screen image information and the vertical screen image information both meet the horizontal screen proportion and the vertical screen proportion of the preset file is further judged, and the original image proportion of the horizontal screen image information and/or the vertical screen image information which are not met is cut according to the horizontal screen proportion and the vertical screen proportion of the preset file, so that the horizontal screen file and the vertical screen file which are generated according to the cut horizontal screen image information and the vertical screen image information can be displayed in a full screen mode when being uploaded to different platforms. That is to say, in the present disclosure, by using the characteristics of multiple cameras on the mobile device, two cameras can be controlled to simultaneously shoot the horizontal screen image and the vertical screen image of the same scene, that is, once shooting is performed, the horizontal screen image information and the vertical screen image information of the scene (that is, image information with different proportions) can be obtained at the same time, and the horizontal screen image information and/or the vertical screen image information that do not satisfy the horizontal-vertical screen proportion of the preset file are cut, so that the horizontal screen proportion and the vertical screen proportion of the preset file are both satisfied with the shot horizontal-vertical screen image information, which not only reduces information loss caused by cutting the image at the later stage, ensures the consistency of the content of the image, but also improves the shooting efficiency, and saves the shooting time of the user.

step 501: detecting a shooting instruction input by a user, wherein the shooting instruction is an instruction for starting a first camera and a second camera on the mobile equipment to shoot simultaneously;

step 502: according to the shooting instruction, the first camera is controlled to shoot transverse screen image information of the same scene, and the second camera is controlled to shoot vertical screen image information of the same scene, wherein the image centers of the transverse screen image information and the vertical screen image information are overlapped;

in this embodiment, the implementation processes of step 501 and step 502 are the same as those of step 101 and step 102, and are specifically described above, and are not described again here.

Step 503: judging whether the horizontal screen image information and the vertical screen image information both meet the horizontal screen proportion and the vertical screen proportion of a preset file; if yes, go to step 504 and step 507; if not, go to step 505;

step 504: simultaneously displaying the horizontal screen image information and the vertical screen image information to the user;

step 505: clipping the horizontal screen image information and/or the vertical screen image information which are not satisfied;

in this embodiment, steps 501 to 505 are the same as steps 401 to 405 described above, and are described in detail above, and are not described again here.

Step 506: judging whether the image centers of the cut horizontal screen image information and the cut vertical screen image information are overlapped; if not, go to step 507; if so, go to step 509;

the purpose of the judgment is to ensure the image center consistency of the cut transverse screen image information and the cut vertical screen image information, and if the transverse screen image information and the vertical screen image information are not consistent, the adjustment is needed to ensure that the image centers of the transverse screen image information and the vertical screen image information are consistent.

Step 507: adjusting the image center of the cut horizontal screen image information and/or vertical screen image information to enable the cut horizontal screen image information and the cut vertical screen image information to be superposed;

in this step, one adjustment method may determine whether the center points of the horizontal screen image information and the vertical screen image information are the same by comparing the image coordinate points or the focal distance reference points of the horizontal screen image information and the vertical screen image information, and of course, the adjustment method may be the same as the other adjustment method, which is well known in the art and will not be described herein again.

Step 508: displaying the horizontal screen image information and the vertical screen image information after the image center is adjusted to the user;

step 509: displaying the cut horizontal screen image information and vertical screen image information to the user;

step 510: and when the shooting end is detected, generating a horizontal screen file according to the displayed horizontal screen image file information, and generating a vertical screen file according to the vertical screen image information.

Namely, generating corresponding vertical screen image information according to the display of the step 504, the step 507 and the step 508 to generate a vertical screen file.

In this disclosure, in order to ensure consistency between horizontal screen image information acquired by a first camera and vertical screen image information acquired by a second camera, it is necessary to determine whether image centers of the horizontal screen image information and the vertical screen image information after being cut coincide with each other, and adjust image centers of the horizontal screen image information and/or the vertical screen image information that do not coincide with each other, so that image centers thereof coincide with each other.

Optionally, in another embodiment, on the basis of the above embodiment, after the horizontal screen image information and the vertical screen image information with the adjusted image centers are displayed to the user, the method may further include:

adjusting the focal length parameter of the first camera and/or the second camera according to the adjusting instruction; so that the centers of the corresponding horizontal and/or vertical screen image information shot by the adjusted first camera and/or second camera are all in the center of the image display region.

and when or after the shooting is detected to be finished, generating a horizontal screen file according to the information of the horizontal screen image shot by the first camera after the focal length parameter is adjusted and generating a vertical screen file according to the information of the vertical screen image shot by the second camera after the focal length parameter is adjusted.

In this embodiment, after the landscape screen image information and the portrait screen image information with the adjusted image centers are displayed to the user, if the center of the landscape screen image information and/or the center of the portrait screen image information after the center of the image is adjusted does not exceed the center of the corresponding image display area of the screen (for example, the center of the adjusted landscape screen image information does not exceed the center of the image display area, etc.), the user inputs an instruction for adjusting the focal length of the corresponding camera, namely, when the mobile equipment detects an adjusting instruction input by a user, the focal length parameter of the first camera and/or the second camera is adjusted, and adjusting the center of the transverse screen image information recorded by the first camera to be in the center of the transverse screen image display area, and the like.

Optionally, in another embodiment, on the basis of the foregoing embodiment, before the cutting, the method may further include:

In this embodiment, because the requirements (i.e., preset values) of different social platforms on the proportions of uploaded files (e.g., videos or pictures) are different, for example, the mobile phone platform displays the files in a vertical screen mode, and the computer platform displays the files in a horizontal screen mode. Therefore, the video or the picture meeting different social platforms can be shot only by acquiring the proportion requirement of different social platforms on the uploaded video or the picture.

Optionally, in another embodiment, on the basis of the above embodiment, after the horizontal screen image information and the vertical screen image information are simultaneously displayed to the user and before it is detected that the shooting is finished, the method may further include:

detecting a switching instruction input by a user;

switching the first camera to a third camera on the mobile equipment or switching the second camera to a fourth camera on the mobile equipment according to the switching instruction; or simultaneously switching the first camera to the third camera and switching the second camera to the fourth camera, wherein the third camera is an alternative camera with the original proportion of the image shot by the first camera; the fourth camera is an alternative camera with the original proportion of the image shot by the second camera;

and when or after the shooting is detected to be finished, generating a horizontal screen file according to the displayed horizontal screen image file information, and generating a vertical screen file according to the vertical screen image information.

In this embodiment, when the user sees the horizontal screen image information and the vertical screen image information in the display screen, if the user feels that the image needs to be adjusted, the user can select the corresponding horizontal screen image information and/or the corresponding standby camera corresponding to the vertical screen image information according to the need, so as to take a better image picture or video picture.

For easy understanding, it is assumed that there are 2 rear cameras on the mobile phone, and the image sensing elements (COMS) of the 2 cameras are all 4: for example, as shown in fig. 6, fig. 6 is a schematic diagram of image sensing elements of two rear cameras on a mobile device according to an exemplary embodiment, where the image sensing elements (COMS) of the two rear cameras are 4:3 is taken as an example.

In this embodiment, when the mobile phone is in the vertical state, since the image sensing elements (COMS) of the 2 cameras are all 4:3, actually requiring the cross-screen ratio of the video to be 16:9, and the vertical screen ratio is 9: for example, 16, the horizontal screen ratio and the vertical screen ratio of the original set file are required.

Therefore, the horizontal screen ratio of the video (original picture) shot by the 2 cameras is 4:3, and the vertical screen ratio is 4: 3; therefore, the picture information collected by the 2 cameras needs to be cut, and the horizontal screen ratio and the vertical screen ratio after cutting are 16:9 and 9:16 respectively.

Since the image sensing elements or modules (COMS) of these 2 cameras are all 4:3, the centers of the framing pictures of the 2 cameras are consistent, and adjustment is not needed.

The mobile phone screen displays the framing pictures of the 2 cameras, the centers of the pictures are consistent, the displayed pictures are as shown in fig. 7, and fig. 7 shows a schematic diagram for simultaneously displaying horizontal screen image information and vertical screen image information acquired by the two cameras according to an exemplary embodiment.

Further, the focal length of the vertical-screen camera can be independently adjusted according to needs, and the horizontal-screen camera remains unchanged, as shown in fig. 8, fig. 8 shows a schematic diagram showing horizontal-screen image information and vertical-screen image information after the focal length of the vertical-screen camera is adjusted according to an exemplary embodiment.

And finally, after the shooting is detected to be finished, generating a horizontal screen file according to the displayed horizontal screen image file information, and generating a vertical screen file according to the vertical screen image information. I.e. 2 video files are obtained simultaneously: horizontal screen files and vertical screen files.
