Abstract

An electronic device comprising: a display configured to output image data; and at least one processor configured to: detect an input; select a portion of the image data based on the input; and generate a preview of the image data based on the selected portion.

Claims

1. An electronic device comprising:

a memory storing instructions;

a display; and

at least one processor, coupled to the display, configured to execute the stored instructions to;

display a preview image being acquired by a camera module of the electronic device, the preview image including simultaneous display of a first object and a second object;

after displaying the preview image including simultaneous display of the first object and the second object, detect a first touch input to the first object, followed by a second touch input to the second object, wherein;

in response to detecting the first touch input, a focus is formed on the first object as to identify, from the preview image, the first object, and

the second touch input is detected to the preview image disposed on the second object, and is received within a predesignated time from a time at which the first touch input is detected;

in response to detecting the second touch input, determine a partial area of the preview image, wherein the partial area includes an entirety of the second object, excludes an entirety of the first object, and is less than an entire area of the preview image;

in response to receiving a capture command for the preview image, store a current image of the preview image focused on the first object; and

after storing the current image responsive to the capture command, generate a thumbnail image including the partial area less than the entire area of the preview image, and including the second object.

2. The electronic device of claim 1, wherein the at least one processor is configured to:

determine at least one frame corresponding to a reception timing of at least one touch input among plurality of frames of the preview image, and

display the thumbnail image based on the determined at least one frame.

3. The electronic device of claim 2,

wherein the at least one processor is configured to determine the thumbnail image based on a reception location of the at least one touch input, and

wherein when the focus is formed on the first object responsive to the first touch input, no focus is formed on a background screen portion of the preview image, the background screen portion including the second object.

4. The electronic device of claim 2,

wherein the thumbnail image is a moving image including the at least one frame in which the at least one touch input is detected.

5. The electronic device of claim 1,

wherein the at least one processor is configured to:

identify a first location of the first touch input and a second location of the second touch input, and

determine the partial area including both the first location and the second location.

6. The electronic device of claim 1,

wherein the at least one processor is further configured to:

detect an input for generating a layer of an image superimposed on a screen, and

determine a thumbnail image including the layer of an image.

7. The electronic device of claim 1,

wherein the preview image includes a plurality of frames,

wherein the at least one processor is further configured to detect a voice input or a physical button input while displaying the preview image, and

wherein the partial area is determined based on at least one frame at a reception timing of the voice input or the physical button input among the plurality of frames.

8. The electronic device of claim 1,

wherein the thumbnail image is a moving image which is moved from another partial area including the first object to the partial area including the second object.

9. A method in an electronic device, comprising:

displaying a preview image being acquired by a camera module of the electronic device, the preview image including simultaneous display of a first object and a second object;

after displaying the preview image including simultaneous display of the first object and the second object, detecting a first touch input to the first object, followed by a second touch input to the second object, wherein;

in response to detecting the first touch input, forming a focus on the first object as to identify the first object in the preview image, and

the second touch input is detected to the preview image disposed on the second object, and is received within a predesignated time from a time at which the first touch input is detected;

in response to detecting the second touch input, determining a partial area of the preview image, wherein the partial area includes an entirety of the second object, excludes an entirety of the first object, and is less than an entire area of the preview image;

in response to receiving a capture command for the preview image, storing a current image of the preview image focused on the first object; and

after storing the image responsive to the capture command, generating a thumbnail image including the partial area less than the entire area of the preview image, and including the second object.

10. The method of claim 9, further comprising:

determining at least one frame corresponding to a reception timing of at least one touch input among plurality of frames of the preview image, and

displaying the thumbnail image based on the determined at least one frame.

11. The method of claim 10,

wherein the displaying the thumbnail image comprises determining the thumbnail image based on a reception location of the at least one touch input, and

wherein when the focus is formed on the first object responsive to the first touch input, no focus is formed on a background screen portion of the preview image, the background screen portion including the second object.

12. The method of claim 10,

wherein the thumbnail image is a moving image including the at least one frame in which the at least one touch input is detected.

13. The method of claim 9, further comprising:

identifying a first location of the first touch input and a second location of the second touch input, and

determining the partial area of the image including both the first location and the second location.

14. The method of claim 9, further comprising:

detecting an input for generating a layer of an image superimposed on a screen, and

determining a thumbnail image including the layer of an image.

15. The method of claim 9, further comprising detecting a voice input or a physical button input while displaying the preview image, and

wherein the partial area is determined based on at least one frame at a reception timing of the voice input or the physical button input among a plurality of frames of the preview image.

16. The method of claim 9, wherein the thumbnail image is a moving image which is moved from another partial area including the first object to the partial area including the second object.

17. A non-transitory computer-readable medium comprising one or more processor executable instructions which when executed by at least one processor cause the at least one processor to perform a process comprising the operations of:

displaying a preview image being acquired by a camera module of an electronic device, the preview image including simultaneous display of a first object and a second object;

after displaying the preview image including simultaneous display of the first object and the second object, detecting a first touch input to the first object, followed by a second touch input to the second object, wherein;

in response to detecting the first touch input, forming a focus on the first object as to identify the first object from the preview image, and

the second touch input is detected to the preview image disposed on the second object and is received within a predesignated time from a time at which the first touch input is detected;

in response to detecting the second touch input, determining a partial area of the preview image, wherein the partial area includes an entirety of the second object, excludes an entirety of the first object, and is less than an entire area of the preview image;

in response to receiving a capture command for the preview image, storing a current image of the preview image focused on the first object; and

after storing the image responsive to the capture command, generating a thumbnail image including the partial area less than the entire area of the preview image, and including the second object.

18. The non-transitory computer-readable medium of claim 17, wherein the thumbnail image is a moving image which is moved from another partial area including the first object to the partial area including the second object.
