Abstract

An image obtaining method and an electronic device for implementing the method are disclosed. The method includes: capturing M image frames of a first object by the image capturing unit in a first time period, where M is an integer larger than or equal to 2; determining a first region of the i-th image frame of the M image frames based on a first preset rule; obtaining M sub-image frames from the M image frames based on information of the first region, where the i-th sub-image frame of the M sub-image frames is determined based on the i-th image frame and the information of the first region; obtaining the j-th image frame of the M image frames, where j is the same as or different from i; and generating a first dynamic image of the first object by using the j-th image frame and the M sub-image frames.

First claim

The invention claimed is:

1. An image obtaining method applied to an electronic device, wherein the electronic device comprises an image capturing device, the method comprising:
capturing M image frames of a first object by the image capturing device in a first time period, wherein M is an integer larger than or equal to 2;
determining a first region in an i-th image frame of the M image frames based on a first preset rule;
obtaining M sub-image frames from the M image frames based on information of the first region, wherein an i-th sub-image frame of the M sub-image frames is determined based on the i-th image frame and the information of the first region;
obtaining a j-th image frame of the M image frames; and
generating a first dynamic image of the first object by using the j-th image frame and the M sub-image frames,
wherein i and j are each integers larger than or equal to 1 and smaller than or equal to M.

2. The method according to claim 1 , wherein capturing the M image frames of the first object by the image capturing device in the first time period comprises:
obtaining a first image of the first object by the image capturing device in the first time period; and
obtaining the M image frames based on the first image.

3. The method according to claim 1 , wherein before capturing the M image frames of the first object by the image capturing device in the first time period, the method further comprises:
determining whether the electronic device operates in a first operating mode.

4. The method according to claim 3 , wherein the first operating mode is a video capturing mode or a continuous image capturing mode.

5. The method according to claim 1 , wherein determining the first region in the i-th image frame of the M image frames based on the first preset rule comprises:
determining the first region in the i-th image frame based on an operation of a user; or
determining the first region in the i-th image frame by analyzing the M image frames; or
determining the first region in the i-th image frame by face recognition.

6. The method according to claim 5 , wherein determining the first region in the i-th image frame based on the operation of the user comprises:
determining the first region in the i-th image frame based on a smearing operation of the user; or
determining the first region in the i-th image frame based on a circling operation of the user.

7. The method according to claim 5 , wherein determining the first region in the i-th image frame by analyzing the M image frames comprises:
analyzing the M image frames to identify a region that includes most information changes among the M image frames; and
determining the identified as the first region in the i-th image frame.

8. The method according to claim 1 , wherein the first dynamic image is a Graphics Interchange Format (gif) image.

9. An electronic device comprising an image capturing device, wherein the electronic device comprises a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon that, when executed by the processor, cause the electronic device to:
capture M image frames of a first object by the image capturing device in a first time period, wherein M is an integer larger than or equal to 2;
determine a first region in an i-th image frame of the M image frames based on a first preset rule;
obtain M sub-image frames from the M image frames based on information of the first region, wherein an i-th sub-image frame of the M sub-image frames is determined based on the i-th image frame and the information of the first region;
obtain a j-th image frame of the M image frames; and
generate a first dynamic image corresponding to the first object by using the j-th image frame and the M sub-image frames,
wherein i and j are each integers larger than or equal to 1 and smaller than or equal to M.

10. The electronic device according to claim 9 , wherein the instructions causing the electronic device to capture M image frames of a first object by the image capturing device in a first time period comprises: instructions causing the electronic device to obtain a first image of the first object by the image capturing device in the first time period, and obtain the M image frames based on the first image.

11. The electronic device according to claim 9 , wherein the instructions further cause the electronic device to determine whether the electronic device operates in a first operating mode.

12. The electronic device according to claim 11 , wherein the first operating mode is a video capturing mode or a continuous image capturing mode.

13. The electronic device according to claim 9 , wherein the instructions causing the electronic device to determine a first region in an i-th image frame of the M image frames based on a first preset rule comprises: instructions causing the electronic device to determine the first region in the i-th image frame based on an operation of a user; or determine the first region in the i-th image frame by analyzing the M image frames; or determine the first region in the i-th image frame by face recognition.

14. The electronic device according to claim 13 , wherein the instructions causing the electronic device to determine a first region in an i-th image frame of the M image frames based on a first preset rule comprises: instructions causing the electronic device to determine the first region in the i-th image frame based on a smearing operation of the user; or determine the first region in the i-th image frame based on a circling operation of the user.

15. The electronic device according to claim 13 , wherein the instructions causing the electronic device to determine a first region in an i-th image frame of the M image frames based on a first preset rule comprises: instructions causing the electronic device to analyze the M image frames to identify a region that includes most information changes among the M image frames, and determine the identified as the first region in the i-th image frame.

16. The electronic device according to claim 9 , wherein the first dynamic image is a gif image.
