Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problems in the related art, embodiments of the present invention provide a shooting method, an apparatus, an electronic device, and a storage medium, so as to solve the problem in the related art that the slice rate of a shot image is low.
The shooting method provided by the embodiment of the invention can be applied to the following application scenes, and the following detailed description is given:
the user wants to take the same image with objects in different orientations. As shown in fig. 1, receiving an operation of a user to start a camera, and displaying a first preview picture and a second preview picture on a shooting preview interface, where the first preview picture and the second preview picture are respectively view-finding pictures of cameras in different directions of an electronic device; then, receiving a first input of selecting a target area on a first preview picture; responding to the first input, and displaying an image corresponding to the target area in the second preview screen; receiving a second input of shooting a second preview picture and a target area; and generating a fused image of the second preview screen and the target area in response to the second input, and displaying the fused image to the user.
Therefore, the shooting method in the embodiment of the invention can enable the user to capture the scenery needed by the user nearby without missing the view. On this basis, carry out local editing when shooting the preview, can observe the effect that the image was shot in real time, and then select suitable shooting opportunity to the realization does not need post processing's image to shoot, effectual saving shooting time reduces the shooting cost, has avoided also making the satisfied risk of user through post processing simultaneously, thereby improves the one slice rate of shooting the image.
In addition, as shown in fig. 2, a first input of selecting a target area in the first preview screen is received, and when the target area is the complete first preview screen, the second input may be responded to generate a stitched image of the second preview screen and the panorama of the target area, that is, the stitched image in which the fused image is the panorama. Here, it is satisfied that the user desires to take photos of himself in a plurality of scenes without moving the electronic device to take a panoramic image as in the related art, so that the user having poor image pickup technology can stably take the panoramic image. Meanwhile, if the spliced images are subjected to 3D processing, the 3D panoramic picture which has perfect stereoscopic impression and cannot be distorted in space can be synthesized by the method.
It should be noted that, as shown in fig. 3, the electronic device in the embodiment of the present invention is equipped with cameras with multiple orientations. Wherein the cameras of the plurality of orientations may include a plurality of cameras of: rear camera 31, front camera 32, left camera 33, right camera 34, top camera 35, lower camera 36.
Here, the camera in each orientation in the embodiment of the present invention may be set as at least one camera, for example: the rear camera 31 has double-shot or triple-shot. In some possible implementation scenarios, the first preview picture and the second preview picture may be acquired by any two cameras in the multiple cameras, that is, two cameras in different directions may acquire pictures, or two cameras in the same direction and different images may acquire pictures. For example, as shown in fig. 4, when a user wants to capture an intersection portion in different frames acquired by two cameras (i.e., frames acquired by different cameras in the same orientation or cameras in different orientations), and each frame is a frame in which an object in the frame is presented at a different zoom factor, the above-mentioned manner may also be adopted, so that the user can acquire a plurality of objects displayed at different zoom factors in one fused image without performing post-image processing in different capture ranges and zoom factors.
In summary, based on the application scenario, the following describes the shooting method provided by the embodiment of the present invention in detail.
Fig. 5 is a flowchart of a shooting method according to an embodiment of the present invention.
As shown in fig. 5, the shooting method may specifically include steps 510 to 530, and specifically may include:
step 510, receiving a first input of selecting a target area in a first preview picture under the condition that the first preview picture and a second preview picture are displayed on a shooting preview interface; step 520, responding to the first input, and displaying an image corresponding to the target area in the second preview screen; step 530, receiving a second input of shooting a second preview picture and a target area; and 540, responding to the second input, and displaying the second preview picture and the fused image of the target area.
Therefore, the shooting method in the embodiment of the invention can enable the user to capture the scenery needed by the user nearby without missing the view. On this basis, carry out local editing when shooting the preview, can observe the effect that the image was shot in real time, and then select suitable shooting opportunity to the realization does not need post processing's image to shoot, effectual saving shooting time reduces the shooting cost, has avoided also making the satisfied risk of user through post processing simultaneously, thereby improves the one slice rate of shooting the image.
Thus, the above steps will be explained in detail:
referring to step 510, since the method provided in the embodiment of the present invention may be applied to multiple scenes, and thus the first preview screen and the second preview screen in the embodiment of the present invention are also different according to different application scenes, and states of the preview screens are also different, the embodiment of the present invention may take the following three possible examples, which may be specifically shown as follows:
in one possible embodiment, the first preview screen and the second preview screen are respectively the viewfinder screens of the cameras in different orientations of the electronic device.
In another possible embodiment, the first preview screen and the second preview screen are respectively view-finding screens of cameras in different orientations of the electronic device (or view-finding screens of different cameras in the same orientation), the view-finding screens captured in the first preview screen and the second preview screen have an intersection, and the zoom multiples corresponding to the first preview screen and the second preview screen are different.
In yet another possible embodiment, the first preview screen and the second preview screen are respectively a viewfinder screen of a camera in different orientations of the electronic device, and the first preview screen and the second preview screen are screens which are acquired at the same time and have at least one same area.
Referring to step 520, in the embodiment of the present invention, two ways are provided to display the image corresponding to the target area in the second preview screen.
In one aspect, the electronic device automatically displays the target area in the second preview screen according to preset parameters (e.g., size and position information of the target area in the second preview screen) when receiving the first input. Responding to the first input, and adjusting the characteristic parameters of the second preview picture by using a double-shot alignment algorithm; and displaying the target area in the second preview picture according to the characteristic parameters. Therefore, the operation of the user can be reduced, and the shooting efficiency can be improved.
And the other way is that the electronic equipment generates a floating window corresponding to the target area according to the target area when receiving the first input, so that the user can adjust the size and the position of the target area according to the requirement of the user. Responding to a first input, displaying a movable floating window in a first preview picture by using a double-shot alignment algorithm, wherein the floating window comprises a target area; receiving a third input of moving the floating window into the second preview screen; in response to a third input, a target area is displayed in the second preview screen. Therefore, personalized requirements can be provided for the user, and the user experience is enhanced.
Based on this, in a possible embodiment, before the step of displaying the target area in the second preview screen referred to above, the method further comprises: receiving a fourth input to change the size of the floating window; in response to a fourth input, the enlarged or reduced target area is displayed in the second preview screen at a zoom scale associated with the fourth input.
Thus, after the user adjusts the target area in the second preview screen, the second preview screen or the first preview screen and the second preview screen may be photographed as required, that is, step 530 is executed.
Referring to step 530, in a scenario where the user only wants to capture a finder in the second preview screen, the second input is used to represent an input for capturing the second preview screen and the target area; alternatively, when the user wants to capture another preview screen (e.g., the first preview screen) while capturing the second preview screen in addition to capturing the second preview screen, the second input may also be used to characterize capturing the first preview screen and the second preview screen. Therefore, the preview picture required by the user can be shot according to the requirement of the user, and the requirement of individual customization is provided for the user.
Thus, after receiving the input of the photographing, the electronic device may generate the fused image according to the second input, and refer to step 540 for specific contents.
Referring to step 540, in an embodiment of the present invention, fused images in different forms may be generated and displayed based on different scenes, as shown in detail below.
Based on three possible embodiments in step 510, this step generates a fused image of the second preview screen and the target area in response to the second input. The fused image can be a fused image of a target area in the first preview picture and the second preview picture; alternatively, the first preview screen and the second preview screen may be connected to form a panoramic mosaic image.
Here, when the fused image is a stitched image, step 540 may specifically include: when the first preview picture and the second preview picture are framing pictures with different shooting ranges and the target area is the first preview picture, displaying a spliced image of the second preview picture and the panorama of the target area by utilizing characteristic pixel matching.
Therefore, when the user expects to shoot the photos in a plurality of scenes, the user does not need to move the electronic equipment to shoot the panoramic image as in the prior art, and therefore the user with poor shooting technology can stably shoot the panoramic image.
Based on this, in a possible embodiment, after the electronic device acquires the stitched image, the stitched image may be further subjected to 3D processing (for example, inputting the stitched image into a 3D model) to obtain a 3D panoramic image, and since the panoramic image is not taken via the mobile electronic device and is the first preview screen and the second preview screen which are taken under relatively stable conditions, the 3D panoramic image with full stereoscopic effect and without spatial distortion may be synthesized.
In addition, based on shooting a panoramic image, another possible scenario is provided in the embodiments of the present invention, that is, when the first preview picture and the second preview picture have an intersection portion of the captured viewfinder pictures, and the intersection portion includes a target area, a user may remove the target area in the first preview picture without wanting the target area to appear in the last shot image, so that the second preview picture may also remove the target area, and the specific implementation manner is as follows, before step 540, the method further includes:
when the first preview picture and the second preview picture comprise the same target object, receiving a fifth input of removing a first area where the target object in the first preview picture is located; in response to a fifth input, removing the first area in the first preview screen and filling the first area with the second area; the second area is determined as the target area.
Based on this, step 540 is executed, so that image shooting without post-processing is realized, shooting time is effectively saved, shooting cost is reduced, and meanwhile, the risk that the user cannot be satisfied by post-processing is avoided, and therefore the filming rate of shot images is improved.
In addition, according to another possible embodiment in step 510, since the zoom factors corresponding to the first preview screen and the second preview screen are different, step 540 may specifically include:
when the first preview picture and the framing picture shot by the second preview picture have an intersection part, acquiring a first zoom multiple of a target area in the first preview picture and a second zoom multiple of the second preview picture;
and when the first zoom multiple is different from the second zoom multiple, displaying the target area in the second preview picture according to the second zoom multiple.
Therefore, the user can acquire a plurality of objects displayed in different zoom magnifications in one fused image without performing post-image processing in different shooting ranges and zoom magnifications.
In summary, to facilitate understanding of the method provided by the embodiment of the present invention, based on the above, the following takes preview pictures obtained by cameras (as shown in fig. 3) in multiple orientations of the electronic device as an example, and the shooting method in the embodiment of the present invention is described as an example.
Fig. 6 is a flowchart of a method for implementing a shooting method according to an embodiment of the present invention.
As shown in fig. 6, the method may include steps 610 to 670, which may be specifically as follows:
step 610, receiving a preset operation of a user to start an application program for shooting an image.
And step 620, responding to preset operation, starting a plurality of accessed cameras of the electronic equipment to acquire a preview screen of each camera.
In step 630, a plurality of preview screens are displayed on the shooting preview interface.
As shown in fig. 7, the plurality of preview screens include: a first preview screen corresponding to the rear camera 31, a second preview screen corresponding to the front camera 32, a third preview screen corresponding to the left camera 33, a fourth preview screen corresponding to the right camera 34, a fifth preview screen corresponding to the upper camera 35, and a sixth preview screen corresponding to the lower camera 36.
It should be noted that, the user may select the multi-dimensional scene same frame mode based on the displayed multiple preview pictures, the multiple cameras in multiple directions may present the multiple preview pictures in the same time period in the same interface, and at this time, the stage of selecting the target area may be performed in the preview stage, that is, step 640 is performed.
Step 640 receives a first input selecting a target area in the first preview screen.
Following the example in step 630, as shown in fig. 7, the interfaces where the different preview images in the total 6 orientations are located are front, back, left, right, top and bottom 6 different cameras and/or preview images, respectively, all of which can implement independent editing (e.g., zooming in, zooming out, filtering, beautifying, etc.). Different 6 scenes are displayed in 6 different preview pictures, and a characteristic area hexagram and other imaging objects are arranged behind the 6 different preview pictures. As shown in fig. 8, the user may click on the first preview screen to fullscreen the first preview screen, and use a corresponding gesture (e.g. a general hexagram gesture) on the first preview screen to scratch the image using a pixel point difference algorithm according to the stroked gesture, in anticipation of giving a possible imaging feature region (i.e. target region). If the selection area is wrong, the user can be prompted to reselect again.
Here, if it is desired to implement independent editing for different cameras and/or preview screens, the following steps need to be executed:
a double Alignment algorithm (SAT) is used, for example, between two cameras, and the Alignment of the viewing angle ranges (e.g., the entire preview screen) of the two cameras can be performed by using the algorithm. After alignment, the two cameras can perform independent editing functions, such as zoom in, zoom out, filter flip, and so on. As shown in fig. 7, a rear camera 31 is provided, and a user can select a certain target area in the first preview image, and the electronic device performs matting on the target area selected by the user according to portrait features and pixel difference algorithm matting. After the target area is determined, the front camera 32 aligns and frames the target area in the same second preview screen. As shown in fig. 9, in the case that the second preview screen (only one, before editing and after editing) of the user is actually formed by two cameras simultaneously, the user can select the front camera 32 to align with the previously selected target area (e.g. the five-pointed star in fig. 9) of the rear camera 31 for independent editing, and the effect in the first preview screen of the rear camera 31 is not changed. Thus, the local processing when previewing a certain local under the unique scene can be realized. The area other than the display effect pentagram in the second preview screen is large fov imaged and the pentagram is small fov imaged. Thus, the angle of view other than the five-pointed star and the preview effect in the first preview screen are not changed, but the angle of view and the preview effect of the five-pointed star in the second preview screen are changed (i.e., from the left image before editing to the right image after enlargement). In this way, the p-picture effect can be realized at the highest speed in the preview process under a specific scene, so that the post-image processing is omitted.
Step 650, in response to the first input, displaying an image corresponding to the target area in the second preview screen.
In step 640, after the user selects a corresponding target area, the target area is recorded, and a movable floating window is displayed in the first preview screen by using a bi-shooting alignment algorithm, where the floating window includes the target area, and the user may select an imaging area in different preview screens according to different actual requirements, and drag the target area to other preview screens, that is, receive a third input to move the floating window to the second preview screen, and display the target area in the second preview screen in response to the third input, and at this time, in the process of the preview screens, use an image synthesis algorithm to complete synthesis of the target area into the second preview screen, so that the target area is covered in the preview screen located ahead. Here, for example, if the user selects a target region of a hexagram in the first preview screen, the parameter value (e.g., crop region) of the first preview screen is transferred to the second preview screen for image crop (note that these processes are all implemented during image preview), and then the blending editing between the two regions of the preview screen of each of the two cameras can be implemented.
Alternatively, when the target area is moved to the second preview screen, the post-camera and/or the second preview screen not including the target area may be independently edited or may not be edited (but the target area is already recorded). The user can move the target area to the position where the user selected the target area on the second preview screen.
It should be noted that when the moving target region is shifted from the first preview screen to the second preview screen, the target region is still in the first preview screen (or the first preview screen is removed and the first preview screen in the first preview screen is filled with the target region).
In addition, in some possible embodiments, if the user only selects the target area and does not want to perform composition editing with other preview pictures, the user may select the saving target area and select other images provided by the electronic device (such as downloaded images or images taken in history), and the target area and the other images are fused by using a picture composition technology, that is, the target area selected by the user is overlaid on the other images for saving.
Moreover, when the user can select a function button, that is, a scene of panoramic shooting, a plurality of preview pictures can be subjected to panoramic picture splicing in six directions from the first preview picture to the sixth preview picture according to a preset fov scaling ratio (this ratio ensures that under the condition of special fov, the edges of two images are at the same position capable of being spliced together, so that picture edge splicing is realized), and the spliced picture is a special staple-shaped panoramic picture, so that a different panoramic picture experience is brought to the user. Or inputting the spliced image into a 3D model to obtain a 3D panoramic image.
Step 660 receives a second input to capture a second preview screen and a target area.
Step 670, responding to the second input, displaying the second preview picture and the fused image of the target area.
In one possible example, the fused image is displayed by the electronic device while the fused image of the second preview screen and the target area is generated.
Thus, according to the imaging method shown in fig. 6 to 9, the target area may be a target area in any preview screen, or the target area may be moved to a plurality of preview screens, and here, only the first preview screen and the second preview screen are described as an example, but in an actual application, the area in each preview screen may be moved to another preview screen, and the movement may be repeated.
In summary, in the embodiments of the present invention, when the first preview screen and the second preview screen are displayed on the shooting preview interface, a first input for selecting the target area in the first preview screen is received; the first preview picture and the second preview picture are respectively view-finding pictures of the cameras on the electronic equipment in different directions; then, a target area is determined to be selected in the first preview screen, the target area is displayed in the second preview screen, and a fused image of the second preview screen and the target area is generated according to user input. Therefore, the shooting method in the embodiment of the invention can enable the user to capture the scenery needed by the user nearby without missing the view. On this basis, carry out local editing when shooting the preview, can observe the effect that the image was shot in real time, and then select suitable shooting opportunity to the realization does not need post processing's image to shoot, effectual saving shooting time reduces the shooting cost, has avoided also making the satisfied risk of user through post processing simultaneously, thereby improves the one slice rate of shooting the image.
