Abstract

A method for selecting an image based on burst shooting is provided, which relates to the field of terminal technologies. The method includes: an electronic device displays a preview interface; detects a first operation used to start burst shooting; obtains N images; then performs scene recognition based on K images that meet an image quality screening condition, to determine a shooting scene; and finally determines M images based on the shooting scene, where N is greater than or equal to K, N is greater than or equal to M, N and K are positive integers greater than 1, and M is a positive integer greater than or equal to 1. This technical solution helps improve quality of an image obtained by the electronic device through screening, thereby improving user satisfaction with an image that is automatically obtained through screening during burst shooting by the electronic device.

First claim

What is claimed is:

1. A method comprising:
displaying, by an electronic device comprising a camera and a display, a preview interface on the display, wherein the preview interface displays an image captured by the camera;
detecting, by the electronic device, a first operation of a user that indicates to start burst shooting using the camera;
in response to detecting the first operation, obtaining, by the electronic device, N first-resolution images captured by the camera using burst shooting;
performing down-sampling on the N first-resolution images to obtain N second-resolution images;
performing, by the electronic device, scene recognition based on K images that meet an image quality screening condition in the N second-resolution images, to determine a shooting scene;
determining, by the electronic device, M second-resolution images from the N second-resolution images based on an image content screening condition corresponding to the shooting scene, wherein N is greater than or equal to K, N is greater than or equal to M, N and K are positive integers greater than 1, and M is a positive integer greater than or equal to 1;
displaying, by the electronic device, the M second-resolution images on the display; and
in response to detecting a second operation performed by a user on a first image in the M second-resolution images, displaying, by the electronic device, a second image on the display in full screen, wherein the second image is a first-resolution image corresponding to the first image.

2. The method according to claim 1 , wherein the determining, by the electronic device, M second-resolution images from the N second-resolution images based on an image content screening condition corresponding to the shooting scene comprises:
determining, by the electronic device, the M second-resolution images that meet the image content screening condition from Q images, wherein the Q images are all images that meet the image quality screening condition in the N second-resolution images, M≤Q≤N, and Q is a positive integer.

3. The method according to claim 1 , wherein after the displaying, by the electronic device, the M second-resolution images on the display, the method further comprises:
in response to detecting an operation that the user selects at least one image from the M second-resolution images, storing, by the electronic device, the at least one image.

4. The method according to claim 1 , wherein the performing, by the electronic device, the scene recognition based on the K images that meet the image quality screening condition in the N second-resolution images, to determine the shooting scene comprises:
performing, by the electronic device, the scene recognition based on preset scene recognition priority information and the K images that meet the image quality screening condition in the N second-resolution images, to determine the shooting scene.

5. The method according to claim 4 , wherein the preset scene recognition priority information indicates that a descending order of scene recognition priorities is: a jumping scene, a look-back scene, and another scene.

6. The method according to claim 1 , wherein the performing, by the electronic device, the scene recognition based on the K images that meet the image quality screening condition in the N second-resolution images, to determine the shooting scene comprises:
each time the electronic device obtains an image captured by the camera in the burst shooting, determining, by the electronic device, whether the image captured by the camera meets the image quality screening condition; and when the image meets the image quality screening condition, caching, by the electronic device, the image; or when the image does not meet the image quality screening condition, deleting, by the electronic device, the image; and
determining, by the electronic device, that there are K cached images that meet the image quality screening condition, and performing the scene recognition based on the K cached images that meet the image quality screening condition, to determine the shooting scene.

7. The method according to claim 1 , wherein the image quality screening condition comprises one or more of an image definition screening condition, an image contrast screening condition, an image brightness screening condition, an image exposure screening condition, an image saturation screening condition, a condition indicating whether there is a color block in an image, or a condition indicating whether there is a color cast in an image.

8. An electronic device comprising:
a display;
a camera;
one or more processors; and
a non-transitory memory, wherein the memory stores one or more computer programs, the one or more computer programs comprise instructions, and when the instructions are executed by the electronic device, the electronic device is caused to perform:
displaying a preview interface on the display, wherein the preview interface displays an image captured by the camera;
detecting a first operation of a user that indicates to start burst shooting using the camera;
in response to detecting the first operation, obtaining N first-resolution images captured by the camera using burst shooting;
performing down-sampling on the N first-resolution images to obtain N second-resolution images;
performing scene recognition based on K images that meet an image quality screening condition in the N second-resolution images, to determine a shooting scene;
determining M second-resolution images from the N second-resolution images based on an image content screening condition corresponding to the shooting scene, wherein N is greater than or equal to K, N is greater than or equal to M, N and K are positive integers greater than 1, and M is a positive integer greater than or equal to 1;
displaying, by the electronic device, the M second-resolution images on the display; and
in response to detecting a second operation performed by a user on a first image in the M second-resolution images, displaying, by the electronic device, a second image on the display in full screen, wherein the second image is a first-resolution image corresponding to the first image.

9. The electronic device according to claim 8 , wherein when the instructions are executed by the electronic device, the electronic device is caused to perform:
determining the M second-resolution images that meet the image content screening condition from Q images, wherein the Q images are all images that meet the image quality screening condition in the N second-resolution images, M≤Q≤N, and Q is a positive integer.

10. The electronic device according to claim 8 , wherein when the instructions are executed by the electronic device, after determining the M images, the electronic device is caused to further perform:
automatically storing the M images, and deleting an image in the N second-resolution images other than the M images.

11. The electronic device according to claim 8 , wherein when the instructions are executed by the electronic device, after displaying the first image on the display in full screen, the electronic device is caused to further perform:
in response to a third operation performed by the user on the first image, exiting full-screen display of the first image, and displaying the M second-resolution images on the display.

12. The electronic device according to claim 8 , wherein when the instructions are executed by the electronic device, after displaying the first image on the display in full screen, the electronic device is caused to further perform:
in response to detecting an operation that the user selects at least one image from the M second-resolution image
