Abstract

A method of operating an electronic device is provided. The method of operating an electronic device includes displaying an image of a first resolution, determining at least a partial region of the image, and displaying an image of a second resolution corresponding to the partial region.

Claims

1. A method in an electronic device, the method comprising:

receiving an image;

outputting the image into a first image having a first resolution through a down sampling operation within an image sensor, the first resolution being lower than a resolution supported in the image sensor;

displaying the first image;

determining at least a partial region of the first image;

acquiring a second image having a second resolution corresponding to the partial region, the second resolution being higher than the first resolution; and

displaying the second image.

2. The method of claim 1, wherein the determining of at least a partial region comprises determining the partial region based on at least one user input.

3. The method of claim 1, wherein the determining of at least a partial region comprises determining the partial region based on attribute information of the first resolution image.

4. The method of claim 3, wherein the attribute information comprises at least one of a pattern, a size, and a resolution of the first resolution image.

5. The method of claim 1, wherein the partial region comprises an image area corresponding to at least one of an iris, a face, a text, and a barcode.

6. The method of claim 1, wherein the first resolution and the second resolution have the same pixel number.

7. The method of claim 1, further comprising determining whether the second resolution is equal to or greater than a reference resolution for authentication.

8. The method of claim 7, further comprising increasing the second resolution by a predetermined value, if the second resolution is less than a reference resolution for authentication.

17. A non-transitory computer readable storage medium that stores at least one program comprising instructions that enable an electronic device to perform the method of claim 1, when being executed by the electronic device.

9. An electronic device comprising:

a display device;

at least one image sensor; and

at least one processor,

wherein the processor is configured to;

receive an image,

output the image into a first image having a first resolution through a down sampling operation within the at least one image sensor, the first resolution being lower than a resolution supported in the image sensor,

display the first image,

determine at least a partial region of the first image,

acquire a second image having a second resolution corresponding to the partial region, the second resolution being higher than the first resolution, and

display the second image.

10. The electronic device of claim 9, wherein the processor is further configured to determine the partial region based on at least one user input.

11. The electronic device of claim 9, wherein the processor is further configured to determine the partial region based on attribute information of the image.

12. The electronic device of claim 11, wherein the attribute information comprises at least one of a pattern, a size, and a resolution of the first resolution image.

13. The electronic device of claim 9, wherein the partial region comprises an image area corresponding to at least one of an iris, a face, a text, and a barcode.

14. The electronic device of claim 9, wherein the processor is further configured to enable the first resolution and the second resolution to have the same pixel number.

15. The electronic device of claim 9, wherein the processor is further configured to determine whether the second resolution is equal to or greater than a reference resolution for authentication.

16. The electronic device of claim 15, wherein the processor is further configured to increase the second resolution by a predetermined value, if the second resolution is less than a reference resolution for authentication.
