You can see me sitting opposite to the star to eat together, and occasionally can look at the four eyes. 3) If the front screen and the back screen (or the existing video) exist at the same time and under the sound background, the matching degree of the video area shot by the back shot or the front shot is very high, the target (person/object) (to be replaced) in the sub-version is appointed, and the target and the object are automatically combined according to the condition requirement. Typical scenario: in a concert, I and the star appear in a video picture, and the I and the star sing together and even have the antiphonal singing effect.
As shown in fig. 3, in an embodiment of the present invention, there is provided a photographed image composing method, in which a terminal has a first portion and a second portion that are movably connected, the first portion has a first screen and a first camera thereon, and the second portion has a second screen and a second camera thereon. A mobile phone with two cameras and two screens is shown in fig. 2.
The method of the embodiment comprises the following steps:
step S310, a first image captured by the first camera is displayed through the first screen.
And step S320, displaying a second image photographed by the second camera through the second screen.
Step S330, identifying the content which does not exist in the second image in the first image, selecting the target area according to the content, and selecting the replacement area from the second image.
In this embodiment, 1) the first screen displays a photograph as a daughter board, the second screen displays a video as a mother board, a selected target area in the daughter board is designated, and a certain frame or certain areas of certain frames in the mother board are designated as a replacement or overlay target. 2) The first screen display video is used as a daughter board, the second screen display video is used as a mother board, a video target area in a certain time selected in the daughter board is designated (the video target area can be provided with a sound part or can be muted), and a certain area in the mother board within a certain time interval or within the same time interval is selected as a replacement or coverage target. 3) The daughter board and the mother board can be locked at the same or different places in the daughter board and the mother board after the matching degree reaches a certain value (self-defined) through scanning and comparison according to the stored coordinate parameters (longitude and latitude records), background, environment, picture content and the like.
In this embodiment, according to the comparison of the shooting parameters of the pictures, the key buildings or landmarks are scanned and judged, and different content parts in the daughter boards are intelligently combined into the master, i.e., the target area is selected.
Step S340, when the first image is a video image, extracting an image with a preset frame number or a preset time range in the target region for composition, and when the second image is a video image, deleting an image with a preset frame number or a preset time range in the replacement region and then performing composition.
In this embodiment, 1) strip single or multiple photo areas (single daughter board & multiple daughter boards displayed on screen) into some frames of the master video, compositing. 2) And stripping a certain frame of picture area in the video in the daughter board, moving the certain frame of picture area to the mother board picture to replace the specified area, and synthesizing. 3) And stripping certain locking areas in the video in the daughter board in a certain period, moving the daughter board to the locking areas in the master board in a certain period for replacement or overlapping, and synthesizing.
In this example, 1) photo merging: the method comprises the steps of combining the existing photos, or combining and updating and replacing the existing shot photos, selecting any one screen of the photos shot corresponding to the front shot and the back shot as a master plate, selecting the existing photos or the photos shot corresponding to the back shot and the front shot as a sub-plate on a second screen (the sub-plate is an effect picture part to be replaced), and dragging and replacing positions, wherein the method can be realized by dragging two screens. The picture achieves the natural effect of observing, adjusting and combining the current affair effect.
Examples are: and selecting the picture 1 as a daughter board to be placed on a first screen, and selecting a content area required in the picture 1 to be locked for standby. And selecting a picture 2 which can be combined as a comparison picture, placing the picture 2 as a master on a second screen, and directly dragging the locking area of the picture 1 to the master of the second screen for replacement. (the master can also select a certain area to be replaced by the lock, but is not necessary)
2) Video-containing processing principles: the photos are merged into a certain frame of video, or a certain picture in the video is intercepted and replaced into the photos.
And the picture- > video is divided into the picture content of a certain frame of the selected video combined on the current shot or the existing picture, the picture selected by the first screen is used as a daughter board, and the video displayed by the second screen is used as a master board. The picture content in the daughter board selects the area to be deducted, and the number of the area is single or multiple. And locking the picture of the replaced or overlapped area in the video displayed by the second screen, moving the content in the daughter board to the corresponding position of the master board, and synthesizing.
And video- > pictures are divided into currently shot or existing videos, contents of certain areas in the selected pictures are combined, the pictures in the video area selected by the first screen are used as daughter boards, and the pictures displayed by the second screen are used as mother boards. Video picture content in the daughter board, selecting the area to be deducted, single or multiple. And moving the content in the daughter board to the corresponding position of the master mask, replacing or overlapping, and synthesizing.
Video- > video, some content in another video is merged on the video that is currently taken or has been taken. And (4) overlapping and synthesizing after replacement. One video is selected to be displayed on any screen as a master plate, the other selected video is selected to be a sub-plate on a second screen (the sub-plate is a part of video stream, certain frame pictures and the like which are about to be used when being extracted), and the content in the sub-plate is selected and locked. Locking the approximate area to be replaced in the master, dragging the content of the second screen master into the first screen master, and replacing the area with the overlapped locking time period. Slightly adjusting and combining.
One master can be selected to correspond to a plurality of daughter boards for editing, for example: the video recorded in the front is used as a master, and the photos or the small videos of the designated area to be replaced or added are designated as different sub-versions (a daughter board 1 and a daughter board 2), and the sub-versions are replaced according to the variable area of the master so as to achieve a natural synthesis effect.
Step S350, during the synthesis, the environmental parameters corresponding to the target region and the environmental parameters corresponding to the portion outside the non-replacement region in the second image are adjusted to a preset goodness of fit.
In the embodiment, when the videos are combined and stored in the first screen and the second screen, the conditions of the background, the spatial coordinates, the sound and the like are almost consistent, and the videos can be automatically combined according to the judgment of the parameters.
In this embodiment, for a video, the environmental scene, the latitude and longitude of the coordinates of the shooting location, and the contrast coincidence degree of the background sound of each frame of the video shot by the two cameras reach a certain value ratio, for example, 70% or more, so as to achieve automatic merging (the merging mode may be in a same star concert mode), retain the same characteristic part, add or replace different matching areas, and combine on the master mask, during which, a matching parameter list may be listed for the user to select (as sound, same sound & same picture, where the picture refers to judging the same latitude and longitude, may be a certain mark building, may be a picture selected and locked by himself in advance, etc.), and the user adjusts, merges and saves the picture according to the conditions. If the matching degree does not reach the standard, for example, the matching degree is lower than 70%, specified adjustment is executed, and operations such as replacement, addition, deletion and the like are performed by manually selecting or presetting the area, and the area is stored after the synthesis requirement is met. (for the same scene, the matching degree is higher, the use probability is large, such as the above concert scene)
Similarly, the automatic merging function can be realized for the photos, and if the matching degree of the technical parameters (focal length, place and time) of the shot photos or the matching degree of the background scanning is more than a certain value (such as 70%), the difference partial images are selectively combined together, and the same part is reserved. The merge is automatic.
Examples of processing for automatic merging: many automatic combination modes can be made, such as a concert mode, for example, on a concert, the star picture and the own picture are naturally combined into a picture video. The star screen is displayed as a mother board, and an alternative part in the star picture is locked and selected (for a video, an evasive means for avoiding the automatic coverage of the content of the mother board exists). This screen is displayed as a daughter board with the video portion of itself automatically fused into the master before locking in place in the selected area. The dream of singing face to face with the star is achieved. It is also possible to design the same activity pattern, where two videos of different target persons, active in the same area, are automatically merged into one.
Furthermore, if a multi-angle intelligent shooting system is added in the shooting process, the interestingness is increased. Synthetically, the freedom of choice is greater. Namely, the device can be rotated to shoot at multiple angles, such as 360-degree rotation in space to track and shoot. The camera double screen cell-phone, 360 degrees rotation control main parts before/after taking, wherein the camera is rotatable also can not support rotatoryly (if the camera is rotatory, the screen can not rotate and also can realize the full angle and shoot). The mobile phone system is built in or the host computer with software system is arranged outside, and the software supports the intelligent shooting, (intelligent) image/image synthesis system. Structurally, the double-screen machine with the double cameras supports the design requirement of multi-angle rotation, and the main body comprises a multi-angle (such as 360-degree space) control chip, a built-in intelligent follow-up shooting system and intelligent image/image synthesis application, as shown in fig. 4.
① automatic focusing, automatic target locking (face recognition, animal recognition, etc.), automatic focusing for recognizing moving area or specially defined area (such as human face, animal), template storage in background for calling, user selection, manual adjustment of selected area, automatic focusing after selection, high-definition shooting, intelligent combination of stored data (such as video or pictures of star scene, ps and star)
② Multi-Angle rotation tracking System & recording track, the Multi-Angle rotation tracking System is based on the movement of the identification and locking area target to follow the shooting, combines the automatic focusing and automatic locking characteristics, simultaneously records the movement track, space dimension, the recording track refers to the movement track in the video shooting process, divided into the locking area track (can be regarded as the small target movement) and the whole video shooting movement track (can be realized by the chip of the rotating shaft and software recording method), the track parameters are mainly used to simulate the replacement scene (such as the selection or the rephotography of the characteristics in the daughter board), the demand is also for the user to naturally merge the videos shot by the front and back cameras.
The pictures or videos shot from multiple angles, particularly videos, can record the moving track of the target, for example, the target rotates 30 degrees left and then rotates 30 degrees right to move, at the moment, the picture running with the star or running with the tiger is required to be simulated, the corresponding characteristic content in the daughter board is detailed and selected, if the characteristic content has the left rotation of 30 degrees and the right rotation of 30 degrees (or certain characteristic actions are simulated again), and therefore special planning (selection or retaking of special targets) and adjustment are reversely carried out according to the track recording parameters, and the videos can be automatically combined.
The automatic shooting may be, for example, automatic area recognition, face recognition, or automatic tracking of moving people and objects. And automatically or manually selecting and locking the area to perform high-definition automatic follow shooting. A handheld shooting mode: moving an area S (X, Y), X and Y represent coordinate areas, S represents a selected area, a video H (X, Y, Z (T)) area, X and Y represent video coordinate areas, Z represents a three-dimensional space coefficient and is related to time, T represents time, and H represents XYZ variation in T time, and the conversion is realized by computer language.
③ fixed object shooting refers to that a user actively controls the focal distance and can adjust the appointed range to realize high-definition shooting of the area part.
④ the intelligent matching of front and back camera refers to automatically selecting any object previewed or shot by a camera as a focus reference, and automatically adjusting corresponding parameters (size and chromatic aberration seen by human eyes, distance judgment, etc.) according to the parameters such as the focus of another camera, so that the picture and video shot by the front and back cameras can be automatically combined to achieve a more natural effect.
According to the technical scheme of the embodiment, one screen of the double-screen mobile phone can rotate 360 degrees in space in structural design, a camera is opened, a starting instruction (dynamic shooting or photo shooting) is clicked after a target or a moving object is manually or automatically selected and locked, people/objects in front are locked, and the mobile shooting is automatically carried out along with the movement of the people/objects, so that the automatic panoramic shooting can be completed. In the process of shooting, if the user starts the intelligent shooting mode, the focal length of the rear camera or the front camera can be automatically adjusted according to the distance matching of people/objects locked by the front camera or the rear camera, so that the optimal distance of people/objects shot by the front camera and the rear camera is reached, and the combination is convenient. The best scene is as follows: the method realizes that the star or the idol is in front of eyes, i can naturally merge pictures or images with the best effect although the star or the idol is not beside the eyes, and the user can see that the user starts the bumper car video together with the height picture of the user.

According to the technical scheme of this embodiment, 1) take the intelligence of the double-screen cell-phone of two cameras to shoot, the enjoyment of shooing after two screens expand can be one screen take a picture screen with the video of shooing, like child's festival performance, can record whole video again in the twinkling of an eye of the snapshot of high definition again, can merge the processing when picture and video can all show out, realize the scene of participating in with the platform, picture or video all can. 2) After shooting, in the video-video combination function, the natural combination of the two videos is experienced, so that the effect that the user runs together with the tiger is achieved. You can see me sitting opposite to the star to eat together, and occasionally can look at the four eyes. 3) If the front screen and the back screen (or the existing video) exist at the same time and under the sound background, the matching degree of the video area shot by the back shot or the front shot is very high, the target (person/object) (to be replaced) in the sub-version is appointed, and the target and the object are automatically combined according to the condition requirement. Typical scenario: in a concert, I and the star appear in a video picture, and the I and the star sing together and even have the antiphonal singing effect.
As shown in fig. 5, in one embodiment of the present invention, a terminal is provided, the terminal having a first portion and a second portion that are movably connected, the first portion having a first screen 510 and a first camera 520 thereon, the second portion having a second screen 530 and a second camera 540 thereon; the terminal further comprises a processor 550, a memory 560 and a communication bus 570;
the processor 550 is configured to execute the photographed image synthesizing program 560 stored in the memory to implement the steps of:
a first image shot by a first camera is displayed through a first screen.
And displaying a second image shot by the second camera through the second screen.
And identifying the content which does not exist in the second image in the first image, selecting a target area according to the content, and selecting a replacement area from the second image.
In this embodiment, 1) the first screen displays a photograph as a daughter board, the second screen displays a video as a mother board, a selected target area in the daughter board is designated, and a certain frame or certain areas of certain frames in the mother board are designated as a replacement or overlay target. 2) The first screen display video is used as a daughter board, the second screen display video is used as a mother board, a video target area in a certain time selected in the daughter board is designated (the video target area can be provided with a sound part or can be muted), and a certain area in the mother board within a certain time interval or within the same time interval is selected as a replacement or coverage target. 3) The daughter board and the mother board can be locked at the same or different places in the daughter board and the mother board after the matching degree reaches a certain value (self-defined) through scanning and comparison according to the stored coordinate parameters (longitude and latitude records), background, environment, picture content and the like.
In this embodiment, according to the comparison of the shooting parameters of the pictures, the key buildings or landmarks are scanned and judged, and different content parts in the daughter boards are intelligently combined into the master, i.e., the target area is selected.
When the first image is a video image, images with preset frame numbers or preset time ranges in the target area are extracted for synthesis, and when the second image is a video image, the images with the preset frame numbers or the preset time ranges in the replacement area are deleted and then synthesized.
In this embodiment, 1) strip single or multiple photo areas (single daughter board & multiple daughter boards displayed on screen) into some frames of the master video, compositing. 2) And stripping a certain frame of picture area in the video in the daughter board, moving the certain frame of picture area to the mother board picture to replace the specified area, and synthesizing. 3) And stripping certain locking areas in the video in the daughter board in a certain period, moving the daughter board to the locking areas in the master board in a certain period for replacement or overlapping, and synthesizing.
In this example, 1) photo merging: the method comprises the steps of combining the existing photos, or combining and updating and replacing the existing shot photos, selecting any one screen of the photos shot corresponding to the front shot and the back shot as a master plate, selecting the existing photos or the photos shot corresponding to the back shot and the front shot as a sub-plate on a second screen (the sub-plate is an effect picture part to be replaced), and dragging and replacing positions, wherein the method can be realized by dragging two screens. The picture achieves the natural effect of observing, adjusting and combining the current affair effect.
Examples are: and selecting the picture 1 as a daughter board to be placed on a first screen, and selecting a content area required in the picture 1 to be locked for standby. And selecting a picture 2 which can be combined as a comparison picture, placing the picture 2 as a master on a second screen, and directly dragging the locking area of the picture 1 to the master of the second screen for replacement. (the master can also select a certain area to be replaced by the lock, but is not necessary)
2) Video-containing processing principles: the photos are merged into a certain frame of video, or a certain picture in the video is intercepted and replaced into the photos.
And the picture- > video is divided into the picture content of a certain frame of the selected video combined on the current shot or the existing picture, the picture selected by the first screen is used as a daughter board, and the video displayed by the second screen is used as a master board. The picture content in the daughter board selects the area to be deducted, and the number of the area is single or multiple. And locking the picture of the replaced or overlapped area in the video displayed by the second screen, moving the content in the daughter board to the corresponding position of the master board, and synthesizing.
And video- > pictures are divided into currently shot or existing videos, contents of certain areas in the selected pictures are combined, the pictures in the video area selected by the first screen are used as daughter boards, and the pictures displayed by the second screen are used as mother boards. Video picture content in the daughter board, selecting the area to be deducted, single or multiple. And moving the content in the daughter board to the corresponding position of the master mask, replacing or overlapping, and synthesizing.
Video- > video, some content in another video is merged on the video that is currently taken or has been taken. And (4) overlapping and synthesizing after replacement. One video is selected to be displayed on any screen as a master plate, the other selected video is selected to be a sub-plate on a second screen (the sub-plate is a part of video stream, certain frame pictures and the like which are about to be used when being extracted), and the content in the sub-plate is selected and locked. Locking the approximate area to be replaced in the master, dragging the content of the second screen master into the first screen master, and replacing the area with the overlapped locking time period. Slightly adjusting and combining.
One master can be selected to correspond to a plurality of daughter boards for editing, for example: the video recorded in the front is used as a master, and the photos or the small videos of the designated area to be replaced or added are designated as different sub-versions (a daughter board 1 and a daughter board 2), and the sub-versions are replaced according to the variable area of the master so as to achieve a natural synthesis effect.
Step S350, during the synthesis, the environmental parameters corresponding to the target region and the environmental parameters corresponding to the portion outside the non-replacement region in the second image are adjusted to a preset goodness of fit.
In the embodiment, when the videos are combined and stored in the first screen and the second screen, the conditions of the background, the spatial coordinates, the sound and the like are almost consistent, and the videos can be automatically combined according to the judgment of the parameters.
In this embodiment, for a video, the environmental scene, the latitude and longitude of the coordinates of the shooting location, and the contrast coincidence degree of the background sound of each frame of the video shot by the two cameras reach a certain value ratio, for example, 70% or more, so as to achieve automatic merging (the merging mode may be in a same star concert mode), retain the same characteristic part, add or replace different matching areas, and combine on the master mask, during which, a matching parameter list may be listed for the user to select (as sound, same sound & same picture, where the picture refers to judging the same latitude and longitude, may be a certain mark building, may be a picture selected and locked by himself in advance, etc.), and the user adjusts, merges and saves the picture according to the conditions. If the matching degree does not reach the standard, for example, the matching degree is lower than 70%, specified adjustment is executed, and operations such as replacement, addition, deletion and the like are performed by manually selecting or presetting the area, and the area is stored after the synthesis requirement is met. (for the same scene, the matching degree is higher, the use probability is large, such as the above concert scene)
Similarly, the automatic merging function can be realized for the photos, and if the matching degree of the technical parameters (focal length, place and time) of the shot photos or the matching degree of the background scanning is more than a certain value (such as 70%), the difference partial images are selectively combined together, and the same part is reserved. The merge is automatic.
Examples of processing for automatic merging: many automatic combination modes can be made, such as a concert mode, for example, on a concert, the star picture and the own picture are naturally combined into a picture video. The star screen is displayed as a mother board, and an alternative part in the star picture is locked and selected (for a video, an evasive means for avoiding the automatic coverage of the content of the mother board exists). This screen is displayed as a daughter board with the video portion of itself automatically fused into the master before locking in place in the selected area. The dream of singing face to face with the star is achieved. It is also possible to design the same activity pattern, where two videos of different target persons, active in the same area, are automatically merged into one.
Furthermore, if a multi-angle intelligent shooting system is added in the shooting process, the interestingness is increased. Synthetically, the freedom of choice is greater. Namely, the device can be rotated to shoot at multiple angles, such as 360-degree rotation in space to track and shoot. The camera double screen cell-phone, 360 degrees rotation control main parts before/after taking, wherein the camera is rotatable also can not support rotatoryly (if the camera is rotatory, the screen can not rotate and also can realize the full angle and shoot). The mobile phone system is built in or the host computer with software system is arranged outside, and the software supports the intelligent shooting, (intelligent) image/image synthesis system. Structurally, the double-screen machine with the double cameras supports the design requirement of multi-angle rotation, and the main body comprises a multi-angle (such as 360-degree space) control chip, a built-in intelligent follow-up shooting system and intelligent image/image synthesis application, as shown in fig. 4.

② Multi-Angle rotation tracking System & recording track, the Multi-Angle rotation tracking System is based on the movement of the identification and locking area target to follow the shooting, combines the automatic focusing and automatic locking characteristics, simultaneously records the movement track, space dimension, the recording track refers to the movement track in the video shooting process, divided into the locking area track (can be regarded as the small target movement) and the whole video shooting movement track (can be realized by the chip of the rotating shaft and software recording method), the track parameters are mainly used to simulate the replacement scene (such as the selection or the rephotography of the characteristics in the daughter board), the demand is also for the user to naturally merge the videos shot by the front and back cameras.
The pictures or videos shot from multiple angles, particularly videos, can record the moving track of the target, for example, the target rotates 30 degrees left and then rotates 30 degrees right to move, at the moment, the picture running with the star or running with the tiger is required to be simulated, the corresponding characteristic content in the daughter board is detailed and selected, if the characteristic content has the left rotation of 30 degrees and the right rotation of 30 degrees (or certain characteristic actions are simulated again), and therefore special planning (selection or retaking of special targets) and adjustment are reversely carried out according to the track recording parameters, and the videos can be automatically combined.
The automatic shooting may be, for example, automatic area recognition, face recognition, or automatic tracking of moving people and objects. And automatically or manually selecting and locking the area to perform high-definition automatic follow shooting. A handheld shooting mode: moving an area S (X, Y), X and Y represent coordinate areas, S represents a selected area, a video H (X, Y, Z (T)) area, X and Y represent video coordinate areas, Z represents a three-dimensional space coefficient and is related to time, T represents time, and H represents XYZ variation in T time, and the conversion is realized by computer language.
③ fixed object shooting refers to that a user actively controls the focal distance and can adjust the appointed range to realize high-definition shooting of the area part.
④ the intelligent matching of front and back camera refers to automatically selecting any object previewed or shot by a camera as a focus reference, and automatically adjusting corresponding parameters (size and chromatic aberration seen by human eyes, distance judgment, etc.) according to the parameters such as the focus of another camera, so that the picture and video shot by the front and back cameras can be automatically combined to achieve a more natural effect.
According to the technical scheme of the embodiment, one screen of the double-screen mobile phone can rotate 360 degrees in space in structural design, a camera is opened, a starting instruction (dynamic shooting or photo shooting) is clicked after a target or a moving object is manually or automatically selected and locked, people/objects in front are locked, and the mobile shooting is automatically carried out along with the movement of the people/objects, so that the automatic panoramic shooting can be completed. In the process of shooting, if the user starts the intelligent shooting mode, the focal length of the rear camera or the front camera can be automatically adjusted according to the distance matching of people/objects locked by the front camera or the rear camera, so that the optimal distance of people/objects shot by the front camera and the rear camera is reached, and the combination is convenient. The best scene is as follows: the method realizes that the star or the idol is in front of eyes, i can naturally merge pictures or images with the best effect although the star or the idol is not beside the eyes, and the user can see that the user starts the bumper car video together with the height picture of the user.
