Abstract

Provided is an electronic device including a display configured to display a first image; and one or more processors electrically connected with the display, wherein the one or more processors are configured to: select a region surrounding a first object comprising a first sub-region surrounding a first part of the first object and a second sub-region surrounding a second part of the first object from the first image, apply a first correction scheme to the first sub-region surrounding the first part of the first object, apply a second correction scheme to the second sub-region surrounding the second part of the first object, and generate a second image comprising the corrected first sub-region surrounding the first part of the first object and the corrected second sub-region surrounding the second part of the first object.

First claim

What is claimed is:

1. An electronic device comprising:
a display configured to display a first image; and
one or more processors electrically connected with the display,
wherein the one or more processors are configured to:
identify a region which includes a first object comprising a first sub-region which includes a first part of the first object and a second sub-region which includes a second part of the first object from the first image, identify a first ratio of the first sub-region to the first image and a second ratio of the second sub-region to the first image, adjust the first ratio by applying a first correction scheme to the first sub-region which includes the first part of the first object, and the second ratio by applying a second correction scheme to the second sub-region which includes the second part of the first object, and provide a second image comprising the corrected first sub-region which includes the first part of the first object and the corrected second sub-region which includes the second part of the first object,
wherein the first correction scheme is a correction scheme that changes a size of the first sub-region which includes the first part of the first object, and the second correction scheme is a correction scheme that performs perspective transformation with respect to the second sub-region which includes the second part of the first object.

2. The electronic device of claim 1 , wherein the one or more processors are further configured to identify the second correction scheme with respect to the second sub-region which includes the second part of the first object based on a result of correction with respect to the first sub-region which includes the first part of the first object to which the first correction scheme is applied.

3. The electronic device of claim 1 , wherein the one or more processors are further configured to identify a third correction scheme with respect to a region which includes a second object of the first image, wherein the region which includes the first object and the region which includes the second object are non-overlapping.

4. The electronic device of claim 3 , wherein the one or more processors are further configured to identify the third correction scheme with respect to the region which includes the second object based on at least one of a result of correction with respect to the first sub-region which includes the first part of the first object and a result of correction with respect to the second sub-region which includes the second part of the first object.

5. An electronic device comprising:
a display configured to display a first image; and
one or more processors electrically connected with the display,
wherein the one or more processors are configured to:
identify a region which includes a first object from the first image comprising a first sub-region which includes a first part of the first object and a second sub-region which includes a second part of the first object, identify the first image into a plurality of divisions comprising a first division and a second division, identify the first sub-region which includes the first part of the first object in the first division, identify the second sub-region which includes the second part of first object in the second division, identify a first ratio of the first sub-region to the first image and a second ratio of the second sub-region to the first image, adjust the first ratio by applying a first correction scheme to the first division and the second ratio by applying a second correction scheme to the second division, and provide a second image comprising the corrected first division and the corrected second division,
wherein the first correction scheme is a correction scheme that changes a size of the first division, and the second correction scheme is a correction scheme that performs perspective transformation with respect to the second division.

6. The electronic device of claim 5 , wherein the one or more processors are further configured to identify the second correction scheme with respect to the second division based on a result of correction with respect to the first division to which the first correction scheme is applied.

7. The electronic device of claim 5 , wherein the one or more processors are further configured to apply a third correction scheme with respect to a region which includes a second object of the first image, wherein the region which includes the first object and the region which includes the second object are non-overlapping.

8. The electronic device of claim 7 , wherein the one or more processors are further configured to identify the third correction scheme with respect to the region which includes the second object based on at least one of a result of correction with respect to the first division and a result of correction with respect to the second division.

9. The electronic device of claim 5 , wherein the first division and the second division are divisions along both horizontal and vertical directions of the first image, and wherein the first correction scheme is applied to the first division along the both horizontal and vertical directions and the second correction scheme is applied to the second division along the both horizontal and vertical directions.

10. A method for controlling an electronic device, the method comprising:
displaying a first image on a display;
identifying, from the first image, a first region which includes a first object in the first image comprising a first sub-region which includes a first part of the first object and a second sub-region which includes a second part of the first object;
identifying a first ratio of the first sub-region to the first image and a second ratio of the second sub-region to the first image;
adjusting the first ratio by applying a first correction scheme to the first sub-region which includes the first part of the first object and the second ratio by applying a second correction scheme to the second sub-region which includes the second part of the first object; and
providing a second image comprising the corrected first sub-region which includes the first part of the first object and the corrected second sub-region which includes the second part of the first object,
wherein the first correction scheme is a correction scheme that changes a size of the first sub-region which includes the first part of the first object, and the second correction scheme is a correction scheme that performs perspective transformation with respect to the second sub-region which includes the second part of the first object.

11. The method of claim 10 , wherein the applying of the second correction scheme to the second sub-region which includes the second part of the first object comprises identifying the second correction scheme with respect to the second sub-region which includes the second part of the first object based on a result of correction with respect to the first sub-region which includes the first part of the first object to which the first correction scheme is applied.

12. The method of claim 10 , further comprising:
applying a third correction scheme with respect to a second region of the first image except for the first region.

13. The method of claim 12 , wherein the applying of the third correction scheme to the second region except for the first region comprises identifying the third correction scheme with respect to the second region based on at least one of a result of correction with respect to the first sub-region which includes the first part of the first object and a result of correction with respect to the second sub-region which includes the sec
