Abstract

An electronic device is provided. The electronic device includes a camera, a memory, and at least one processor electrically coupled to the camera and the memory. The at least one processor may obtain a plurality of image frames through the camera, in response to a shooting start command, obtain a shooting command subsequent to the shooting start command, select a first number of image frames from among the plurality of image frames obtained before the shooting command, in response to the shooting command, and generate a first image synthesized based on the selected first number of image frames.

First claim

What is claimed is:

1. An electronic device comprising:
a camera;
at least one processor electrically coupled to the camera; and
memory storing instructions that, when executed by the at least one processor individually or collectively, cause the electronic device to:
obtain a plurality of image frames through the camera, in response to a shooting start command,
obtain a shooting command subsequent to the shooting start command,
determine a shooting environment,
determine a first number, based on the shooting environment,
select the first number of image frames from among the plurality of image frames obtained before the shooting command, in response to the shooting command, and
generate a first image synthesized based on the selected first number of image frames.

2. The electronic device of claim 1 ,
wherein a timer is executed in response to the shooting start command, and
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to store the plurality of image frames in the memory in response to the shooting command subsequent to the shooting start command, in a state where the timer is running.

3. The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to initialize the timer in response to the shooting command.

4. The electronic device of claim 2 , wherein the instructions that, when executed by the at least one processor individually or collectively, cause the electronic device to delete the plurality of image frames stored in the memory in response to an expiry of the timer.

5. The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
determine whether at least one image frame obtained before the shooting start command is stored in the memory;
when the at least one image frame is not stored in the memory, select a second number of image frames from among the plurality of image frames obtained after the shooting start command; and
generate a second image synthesized based on the selected second number of image frames.

6. The electronic device of claim 1 , wherein, when the first number of image frames are selected, the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to select the image frames in a reverse order by which each of the plurality of image frames is obtained.

7. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
select at least one image frame from among the plurality of image frames obtained before the shooting command in response to the shooting command,
select at least one image frame from among the plurality of image frames obtained after the shooting command, and
generate a third image synthesized based on the selected image frames.

8. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
select a criterion image and at least one reference image from among the plurality of image frames, and
generate an image with improved quality by synthesizing the criterion image and the at least one reference image.

9. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
encode the generated first image, and
store the encoded first image in the memory.

10. A method of operating an electronic device, the method comprising:
obtaining a plurality of image frames through a camera included in the electronic device, in response to a shooting start command;
obtaining a shooting command subsequent to the shooting start command;
determining a shooting environment;
determining a first number, based on the shooting environment;
selecting the first number of image frames from among the plurality of image frames obtained before the shooting command, in response to the shooting command; and
generating a first image synthesized based on the selected first number of image frames.

11. The method of claim 10 , further comprising:
executing a timer included in the electronic device in response to the shooting start command; and
storing the plurality of image frames in a memory of the electronic device in response to the shooting command subsequent to the shooting start command, in a state where the timer is running.

12. The method of claim 11 , further comprising:
initializing the timer in response to the shooting command.

13. The method of claim 11 , further comprising:
deleting the plurality of image frames stored in the memory in response to an expiry of the timer.

14. The method of claim 11 , further comprising:
determining whether at least one image frame obtained before the shooting start command is stored in the memory;
when the at least one image frame is not stored in the memory, selecting a second number of image frames from among the plurality of image frames obtained after the shooting start command; and
generating a second image synthesized based on the selected second number of image frames.

15. The method of claim 10 , wherein the selecting of the first number of image frames is selecting of the image frames in a reverse order by which each of the plurality of image frames is obtained.

16. The method of claim 10 , further comprising:
selecting at least one image frame from among the plurality of image frames obtained before the shooting command, based on the shooting environment;
selecting at least one image frame from among the plurality of image frames obtained after the shooting command; and
generating a third image synthesized based on the selected image frames.

17. The method of claim 10 , further comprising:
encoding the generated first image; and
storing encoded first image in memory of the electronic device.

18. A non-transitory recording medium storing computer readable instructions configured to perform:
obtaining a plurality of image frames through a camera, in response to a shooting start command;
obtaining a shooting command subsequent to the shooting start command;
determining a shooting environment;
determining a first number, based on the shooting environment;
selecting the first number of image frames from among the plurality of image frames obtained before the shooting command, in response to the shooting command; and
generating a first image synthesized based on the selected first number of image frames.
