## Abstract

An electronic device is provided. The electronic device includes a housing, a display exposed through a first surface of the housing, a first camera exposed through a second surface of the housing that is opposite to the first surface, a second camera exposed through the second surface, a memory storing an image obtained by the first or second camera, and a processor electrically connected with the display, the first camera, the second camera, and the memory. The processor is configured to output a first image obtained by using the first camera on the display and, when an area recognized as a face in the first image has a size satisfying a specified condition, output a second image obtained by using the second camera on the display.

## Claims

### Claim 1

An electronic device comprising:
a housing;
a display provided at a front side of the electronic device;
a first camera provided at a rear side of the electronic device;
a second camera provided at the rear side of the electronic device;
a memory; and
a processor configured to:
provide a first preview image obtained by the first camera on the display,
while the first preview image obtained by the first camera is displayed on the display, use the second camera to obtain a second preview image using a zooming parameter different from a zooming parameter used by the first camera to capture the first preview image,
provide the second preview image with the first preview image on the display, and
while the second preview image is provided with the first preview image on the display, provide a first user interface item associated with the first preview image for receiving an input for capturing a still image using the first camera, and provide a second user interface item associated with the second preview image for receiving an input for capturing a still image using the second camera.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein, while the second preview image is provided with the first preview image on the display, the processor is further configured to provide a third user interface item for receiving an input for capturing both a still image using the first camera and a still image using the second camera.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
determine if an object is moving in the first preview image, and
if the moving object in the first preview image satisfies a defined condition, automatically use the second camera to obtain the second preview image by zooming in on at least the moving object.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
recognize a face on the first preview image, and
if a portion of the first preview image corresponding to the recognized face satisfies a defined condition, automatically use the second camera to obtain the second preview image by zooming in on a subject corresponding to the recognized face.

### Claim 5 (depends on 4)

The electronic device of claim 4, wherein the defined condition comprises identifying a size of the portion containing the recognized face in relation to the first preview image.

### Claim 6 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
recognize a plurality of faces on the first preview image, and
if a portion of the first preview image corresponding to the recognized faces satisfies a defined condition, automatically use the second camera to obtain the second preview image by zooming in on subjects corresponding to the recognized faces.

### Claim 7 (depends on 6)

The electronic device of claim 6, wherein the defined condition comprises identifying a size of the portion containing the recognized faces in relation to the first preview image.

### Claim 8 (depends on 3)

The electronic device of claim 3, wherein the processor is further configured to:
stop actuating the second camera if the moving object is outside a field of view of the first camera or the moving object stops, and
stop displaying the second preview image.

### Claim 9 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
if a plurality of moving objects are recognized in the first preview image and satisfy a defined condition, display, on the display, a guide to select one of the plurality of moving objects, and
obtain the second preview image based on the selected moving object through the guide.

### Claim 10 (depends on 3)

The electronic device of claim 3, wherein the processor is further configured to:
compute an angle to move a shooting direction of the second camera to track the moving object by analyzing the first preview image and to control an actuator to move the shooting direction of the second camera by the computed angle.

### Claim 11 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
if a plurality of faces are recognized in the first preview image, classify the plurality of faces into one or more groups based on a distance between the plurality of faces, and
obtain the second preview image having a group including a greatest number of faces among the one or more groups.

### Claim 12 (depends on 1)

The electronic device of claim 1, wherein the processor is further configured to:
if a plurality of faces are recognized in the first preview image, classify the plurality of faces into one or more groups based on a distance between the plurality of faces,
display, on the display, a guide to select one of the one or more groups, and obtain the second preview image based on a group selected through the guide.
