## Abstract

A method in an electronic device includes displaying an image on a screen, detecting a swiping of a finger through a sensor, and selecting at least a portion of the image based on the swiping of the finger. An electronic device is provided. The electronic device includes a memory configured to store one or more pieces of fingerprint information, a screen configured to display an image, and at least one processor configured to detect a swiping of a finger through a sensor, and select at least a portion of the image based on the swiping of the finger. Other various embodiments are also disclosed.

## Claims

### Claim 1

A method in an electronic device, the method comprising:
displaying, by a screen, an image on a screen;
detecting, by at least one processor, a swiping of a finger on a fingerprint sensor using the fingerprint sensor;
determining, by the at least one processor, at least a portion of the displayed image to be captured, according to the swiping of the finger on the fingerprint sensor; and
capturing, by the at least one processor, the determined at least the portion of the displayed image in response to detecting a release of the swiping of the finger; and
storing, by the at least one processor, the captured at least the portion of the displayed image in a memory.

### Claim 2 (depends on 1)

The method of claim 1, wherein the finger is swiped in one of an up-to-down direction, a down-to-up direction, a left-to-right direction or a right-to-left direction.

### Claim 3 (depends on 1)

The method of claim 1, wherein a size of the image is determined according to a speed of the swiping of the finger.

### Claim 4 (depends on 3)

The method of claim 3, wherein the size of the determined at least the portion of the displayed image is increased as the speed of the swipe of the finger is faster.

### Claim 5 (depends on 1)

The method of claim 1, wherein a size of the determined at least the portion of the displayed image is decreased when a direction of the swiping switches from a first direction to a second direction.

### Claim 6 (depends on 1)

The method of claim 1, further comprising
scanning, by the fingerprint sensor, a fingerprint of the finger; and
setting the scanned fingerprint acquired from the finger as an identification code for unlocking the stored at least the portion of the displayed image.

### Claim 7 (depends on 6)

The method of claim 6, further comprising providing an image of the fingerprint when the finger is swiped for unlocking the stored at least the portion of the displayed image.

### Claim 8 (depends on 1)

The method of claim 1, further comprising requesting for a re-swiping the finger when the fingerprint information does not include a specified region of a fingerprint of a finger.

### Claim 9 (depends on 1)

The method of claim 1, further comprising inquiring a user to confirm whether to use the scanned fingerprint as an identification code when the finger is released off the fingerprint sensor.

### Claim 10 (depends on 1)

The method of claim 1, further comprising increasing or decreasing the determined at least the portion of the displayed image when a second swiping is performed within a predetermined period of time after the swiping is released.

### Claim 11

An electronic device, comprising:
a memory configured to store one or more pieces of fingerprint information;
a fingerprint sensor;
a screen configured to display an image; and
at least one processor configured to:
detect a swiping of a finger on the fingerprint sensor using the fingerprint sensor;
determine at least a portion of the displayed image to be captured, according to the swiping of the finger on the fingerprint sensor;
capture the determined at least the portion of the displayed image in response to detecting a release of the swiping of the finger; and
store the captured at least the portion of the displayed image in the memory.

### Claim 12 (depends on 11)

The electronic device of claim 11, wherein the finger is swiped in one of an up-to-down direction, a down-to-up direction, a left-to-right direction or a right-to-left direction.

### Claim 13 (depends on 11)

The electronic device of claim 11, wherein a size of the image is determined according to a speed of the swiping of the finger.

### Claim 14 (depends on 11)

The electronic device of claim 11, wherein the size of the determined at least the portion of the displayed image is increased as the speed of the swipe of the finger is faster.

### Claim 15 (depends on 11)

The electronic device of claim 11, wherein a size of the determined at least the portion of the displayed image is decreased when a direction of the swiping switches from a first direction to a second direction.

### Claim 16 (depends on 11)

The electronic device of claim 11, wherein the at least one processor is configured to cause the fingerprint sensor to scan a fingerprint of the finger and set the scanned fingerprint information as an identification code for unlocking the stored at least the portion of the displayed determined image.

### Claim 17 (depends on 16)

The electronic device of claim 16, wherein the processor is configured to provide an image of the fingerprint on the screen when the finger is swiped.

### Claim 18 (depends on 11)

The electronic device of claim 11, wherein the processor is configured to request for re-swiping the finger when the fingerprint is not valid.

### Claim 19 (depends on 11)

The electronic device of claim 11, wherein the processor is configured to inquire a user to confirm whether to use the scanned fingerprint as an identification code when the finger is released off the fingerprint sensor.

### Claim 20 (depends on 11)

The electronic device of claim 11, wherein the processor is configured to increase or decrease the determined at least the portion of the displayed image when a second swiping is performed within a predetermined period of time after the swiping is released.
