Abstract

An image processing method and an apparatus are provided. The image processing method includes receiving information of starting a first camera and a second camera simultaneously to perform photographing; using the first camera to photograph and obtain a first image, and using the second camera to photograph and obtain a second image; and displaying the first image and the second image simultaneously. In the embodiments of the present invention, two cameras are started simultaneously to perform bidirectional photographing, and the images taken by both cameras are displayed simultaneously, so that front and back scene images are captured simultaneously and a panoramic image is obtained.

Claims

1. An image processing method applied to a terminal, the method comprising:

receiving a view reflected or refracted by a panoramic auxiliary lens of a terminal, wherein the terminal has the panoramic auxiliary lens and at least one camera, wherein the panoramic auxiliary lens is used to reflect or refract a surrounding view of the terminal to a photographing area of the camera;

using the camera to obtain a preview image of the view reflected or refracted by the panoramic auxiliary lens, wherein the preview image comprises multiple preview sub-images from different angles;

determining a focusing parameter of the camera according to an operation of adjusting a focus for any preview sub-image of the multiple preview sub-images;

using the at least one camera to photograph the view reflected or refracted by the panoramic auxiliary lens to obtain an image according to the focusing parameter; and

displaying the image obtained by photographing.

2. The method according to claim 1, wherein displaying the image obtained by photographing comprises displaying the image obtained by photographing continuously in a planar expansion manner.

3. The method according to claim 1, wherein after displaying the image obtained by photographing, the method further comprises:

cropping the image obtained by photographing according to a set scale; and

saving the cropped image.

8. The method according to claim 1, wherein displaying the image obtained by photographing comprises displaying the image obtained by photographing continuously in an annular display manner.

9. The method according to claim 1, wherein displaying the image obtained by photographing comprises dividing the image obtained by photographing into multiple images from different angles, and displaying the multiple images from different angles simultaneously.

4. An image processing apparatus applied to a terminal, the apparatus comprising:

a view receiving unit configured to receive a view reflected or refracted by a panoramic auxiliary lens of the terminal, wherein the terminal has the panoramic auxiliary lens and at least one camera, wherein the panoramic auxiliary lens is used to reflect or refract a surrounding view of the terminal to a photographing area of the camera;

a preview subunit configured to use the camera to obtain a preview image of the view reflected or refracted by the panoramic auxiliary lens, wherein the preview image comprises multiple preview sub-images from different angles;

a parameter determining subunit configured to determine a focusing parameter of the camera according to an operation of adjusting a focus for any preview sub-image of the multiple preview sub-images;

an image obtaining unit configured to use the camera to photograph the view reflected or refracted by the panoramic auxiliary lens to obtain an image according to the focusing parameter; and

an image outputting unit configured to display the image obtained by photographing.

5. The apparatus according to claim 4, wherein the image outputting unit is configured to display the image obtained by photographing continuously in a planar expansion manner.

6. The apparatus according to claim 4, further comprising:

a cropping unit configured to crop the image obtained by photographing according to a set scale; and

a saving unit configured to save the cropped image.

7. The apparatus according to claim 5, further comprising:

a cropping unit configured to crop the image obtained by photographing according to a set scale; and

a saving unit configured to save the cropped image.

10. The apparatus according to claim 4, wherein the image outputting unit is configured to display the image obtained by photographing continuously in an annular display manner.

11. The apparatus according to claim 4, wherein the image outputting unit is configured to divide the image obtained by photographing into multiple images from different angles, and display the multiple images from different angles simultaneously.
