The first and second cameras may be ultra-wide angle cameras, for example, the first and second cameras may be 180 ° fisheye lenses.
The following describes in detail the shooting method provided in the embodiment of the present application, taking a fisheye lens with a first camera and a second camera at 180 degrees as an example.
As shown in fig. 1, an embodiment of the present application provides a shooting method, which may include steps 101 to 103:
and step 101, displaying a shooting preview interface.
The shooting preview interface can comprise a first preview image and a third preview image, and the third preview image is obtained by splicing the first preview image and the second preview image.
If the user wants to shoot a wide-angle image or a wide-angle video, the electronic device may be triggered to display a shooting preview interface, where the shooting preview interface may include the first preview image and the third preview image, and may also include the second preview image.
Optionally, the first preview image and the second preview image may be images captured through fisheye lenses with different capturing angles, that is, the first preview image and the second preview image may be preview images of different capturing angles captured at the same image capturing point through fisheye lenses with different capturing angles. For example, a first preview image may be acquired by a first camera and a second preview image may be acquired by a second camera. The second preview image may include a first sub-image and a second sub-image; the third preview image may be a wide-angle image obtained by sequentially stitching the first sub-image, the first preview image, and the second sub-image.
For example, as shown in fig. 2, the second preview image 220 may include a first sub-image 221 and a second sub-image 222, and the third preview image 230 may be a wide-angle image obtained by sequentially stitching the first sub-image 221, the first preview image 210, and the second sub-image 222.
And 102, receiving a first input of the first preview image from a user.
Wherein the first input may be used to determine an image center of the third preview image.
The image center refers to an image center point of the third preview image when all the image areas of the third preview image are displayed.
Optionally, the electronic device determines the image center of the third preview image through the first input, which specifically includes the following two ways: mode 1 is that the electronic device may determine the input position of the first input as the image center of the third preview image; manner 2 is that the electronic device may determine a position in the second preview image opposite to the input position of the first input as the image center of the third preview image.
Illustratively, as shown in fig. 3, the electronic device may display a first preview image in an area 31 of the capture preview interface, a second preview image in an area 32, and a third preview image in an area 33, the first preview image may be first input by the user, and the electronic device may determine an image center 34 of the third preview image from the first preview image in response to the first input.
And 103, responding to the first input, and updating and displaying the third preview image according to the image center.
Optionally, in a case that the center of the image is different from the center of the third preview image in the height direction, the electronic device may first cut the first preview image into a third sub-image, cut the second preview image into a fourth sub-image, and then stitch the third sub-image and the fourth sub-image to obtain the third preview image, and update and display the third preview image.
For example, as shown in fig. 4, the electronic device may determine an image center 41 according to a first input of the user to the first preview image 210, and since the image center 41 and a center 42 of the third preview image 231 before the updated display in the height direction are different in position, the electronic device may first cut the first preview image 210 into the third sub-image 43 along a cutting line f1, cut the second preview image 220 into the fourth sub-image 44 along a cutting line f2, then stitch the third sub-image 43 and the fourth sub-image 44 to obtain the third preview image 232, and finally, the electronic device may cancel the display of the third preview image 231 and update the display of the third preview image 232.
Based on the above-described configuration, when the center of the image is different from the center of the third preview image in the height direction, the first preview image can be cropped into the third sub-image and the second preview image can be cropped into the fourth sub-image in accordance with the center of the image, and therefore, the third preview image centered on the center of the image in the height direction can be obtained.
Optionally, in a case where the center of the image is different from the center of the third preview image in the horizontal direction, the electronic device may crop the second preview image into a fifth sub-image and a sixth sub-image; sequentially splicing the fifth sub-image, the first preview image and the sixth sub-image to obtain a third preview image; and updating and displaying the third preview image.
For example, as shown in fig. 5, the electronic device may determine an image center 51 according to a first input of the user to the first preview image 210, and since the position of the image center 51 is different from the position of the center 52 of the third preview image 231 before the update display in the horizontal direction, the electronic device may cut the second preview image 220 into the fifth sub-image 53 and the sixth sub-image 54 along the cutting line f3, and then, the electronic device may sequentially stitch the fifth sub-image 53, the first preview image 210, and the sixth sub-image 54 to obtain the third preview image 232, and finally, the electronic device may cancel the display of the third preview image 231 and update the display of the third preview image 232.
Based on the above-described aspect, since the second preview image can be cropped into the fifth sub-image and the sixth sub-image in accordance with the image center in the case where the image center is different from the center of the third preview image in the horizontal direction, the third preview image centered on the image center in the horizontal direction can be obtained.
Optionally, after the third preview image is updated and displayed, the electronic device may further receive a second input of the user; capturing a first image corresponding to the first preview image and a second image corresponding to the second preview image in response to the second input; and outputting a third image, wherein the third image is obtained according to the image center, the first image and the second image.
Specifically, under the condition that the user considers that the updated and displayed third preview image meets the own photographing intention, the user can perform second input on the photographing control of the electronic device, correspondingly, the electronic device can receive the second input of the user, and in response to the second input, photograph the first image corresponding to the first preview image and the second image corresponding to the second preview image, then, the first image and the second image are spliced according to the image center to obtain a third image, and finally, the obtained third image is output.

Optionally, before outputting the third image, the electronic device may further receive a third input of the user in a case where the electronic device is updated from the first photographing angle to the second photographing angle; capturing a fourth image and a fifth image in response to the third input; and respectively carrying out image quality enhancement processing on the first image and the second image according to the fourth image and the fifth image.
Illustratively, as shown in fig. 6, after the electronic device acquires a first image 61 through the first camera and a second image 62 through the second camera, the electronic device may output indication information to guide a user to turn the electronic device by 90 ° in the horizontal direction, and then acquire a fourth image 63 through the first camera and a fifth image 64 through the second camera. Since the side edge region "1" of the first image 61 is located in the center region of the fifth image 64, the side edge region "4" of the first image 61 is located in the center region of the fourth image 63, the side edge region "5" of the second image 62 is located in the center region of the fourth image 63, and the side edge region "8" of the second image 62 is located in the center region of the fifth image 64, the electronic device can perform the edge quality enhancement processing on the first image and the second image according to the fourth image and the fifth image, respectively.
Based on the scheme, since the edge image quality enhancement processing can be respectively carried out on the first image and the second image according to the fourth image and the fifth image, the image quality of the first image and the second image can be improved, and the image quality of the finally obtained third image can be improved.
Optionally, after outputting the third image, the electronic device may further display a stereoscopic image corresponding to the third image; receiving a fourth input from the user; updating display of the stereoscopic image in response to the fourth input; the updating the display of the stereoscopic image comprises at least one of: magnifying and displaying the stereoscopic image; displaying the stereoscopic image in a reduced manner; and displaying the image area of the stereoscopic image target visual angle.
Specifically, because the first camera and the second camera are fisheye lenses of 180 degrees, the electronic device can obtain a wide-angle image of 360 degrees through stitching processing of the first image and the second image, and then the electronic device can establish a three-dimensional stereo image of the wide-angle image; in a case where the three-dimensional stereoscopic image is displayed, the electronic device may receive a fourth input of the three-dimensional stereoscopic image by the user; and updating the display stereoscopic image in response to a fourth input; the updating the displayed stereoscopic image may include at least one of: magnifying and displaying the stereoscopic image; displaying the stereoscopic image in a reduced manner; and displaying the image area of the stereoscopic image target visual angle.
Illustratively, the updating of the image region displaying the stereoscopic image including displaying the target angle of view of the stereoscopic image, and the fourth input as the stroke input are taken as examples. The electronic device may synthesize the first image and the second image into a spherical image by an algorithm, and in a case where the spherical image is displayed, a user may perform a slide input on the spherical image, and the electronic device may display image areas of different view angle ranges of the spherical image according to an input direction of the slide input in response to the slide input.
Optionally, the user may also trigger the electronic device to share the stereoscopic image with other users, or save the stereoscopic image locally.
Based on the scheme, the three-dimensional image of the third image can be established, and the three-dimensional image is updated and displayed according to the fourth input of the user, so that the interestingness and intuition of image display can be increased.
Optionally, after outputting a third image, the electronic device may further store the first image, the second image, and the third image; and receiving a fifth input of the user in a case where the third image is displayed; and in response to the fifth input, synthesizing a sixth image according to the first image and the second image, and updating and displaying the third image as the sixth image, wherein the image center of the sixth image is different from the image center of the third image.
Specifically, after the third image is output, the electronic device may store the first image, the second image, and the third image, and when the user is unsatisfied with the image area in the center of the third image, the first image and the second image may be cut and stitched again, so as to obtain a sixth image with an image center different from the third image.
For example, when the user wants to acquire a new stitched image, the user may trigger the electronic device to display the third image, and in the case of displaying the third image, the electronic device may receive a fifth input of the user for the third image; and determining a new image center from the third image in response to a fifth input, and then, the electronic device may crop the first image and the second image according to the newly determined image center, and finally, synthesize the cropped images into a sixth image, where the image center of the sixth image is the new image center determined by the fifth input.
Based on the scheme, the first image, the second image and the third image can be stored, and the sixth image with the image center different from that of the third image is determined according to the first image, the second image and the third image, so that a user can synthesize a new wide-angle image at any time, and the fault tolerance of the user for synthesizing the wide-angle image for the first time is improved.
Optionally, the receiving, by the electronic device, the first input of the user may specifically include: the electronic device receives a first input by a user to a moving object in a first preview image. After the third preview image is displayed in an updated manner, the electronic device may further receive a sixth input of the user; and in response to the sixth input, taking the moving object as an image center, and shooting a first video, wherein a video frame of the first video corresponds to the third preview image.
Specifically, if a user wants to perform video shooting on a certain moving object, the electronic device may be triggered to acquire a video picture within a shooting range of the first camera through the first camera, and acquire a video picture within a shooting range of the second camera through the second camera. Since the first camera and the second camera are fisheye lenses of 180 degrees, the electronic device can acquire a video picture of a moving object in any direction.
After the electronic equipment receives a first input of a user to a moving object in the first preview image, the moving object can be used as a video focus, and a video preview picture taking the moving object as the focus is displayed in a floating window area of the shooting preview interface. Thereafter, the electronic device may receive a sixth input by the user; and in response to a sixth input, capturing a first video centered on the moving object.
Optionally, before receiving the first input, the electronic device may further determine, as a moving object, a photographing object moving most frequently in the photographing preview interface by default.
For example, as shown in fig. 7, in the case of displaying the photographing preview interface, when the user makes a first input to the moving object 71, the electronic device may display a video preview screen 73 focused on the moving object 71 in the floating window area 72. Thereafter, the user may make a sixth input to the video capture control, and the electronic device may capture the first video corresponding to the display in the video preview screen 73 in response to the sixth input.
It should be noted that, when the moving object is within the shooting range of the first camera, the electronic device may display a preview picture acquired by the first camera in the floating window area; and under the condition that the moving object is within the shooting range of the second camera, the electronic equipment can display the preview picture acquired by the second camera in the floating window area.
