## Abstract

A device and method for taking pictures is disclosed. The device includes: a camera; a display; and a processor configured to capture a plurality of temporary images of one or more subjects by using the camera; extract a reconstructed scene from the plurality of temporary images; capture a focused image that a user intends to take a picture by using the camera; generate a subject map in the focused image by using the reconstructed scene; estimate an armature from the subjects selected from the subject map; combine the armature with the focused image; verify whether the composition of the focused image is good or not; and present an instruction to the user to adjust the composition by using the display. The device and method achieves improved photographic composition.

## Claims

### Claim 1

A device for taking pictures, comprising:
a camera;
a display; and
a processor configured to capture a plurality of temporary images of one or more subjects by using the camera;
extract a reconstructed scene from the plurality of temporary images;
capture a focused image of subject matter for which a user intends to take a picture by using the camera;
generate a subject map in the focused image by using the reconstructed scene;
receive a selection of at least one of the one or more subjects from the subject map;
determine an appropriate armature from the at least one of the one or more subjects selected from the subject map;
combine the armature with the focused image;
determine that the composition of the focused image can be improved; and
present an instruction to the user to adjust the composition through an interface on the display.

### Claim 2 (depends on 1)

The device according to claim 1, further comprising a speaker, wherein the processor is further configured to present the instruction to the user as an audible instruction through the speaker.

### Claim 3 (depends on 1)

The device according to claim 1, wherein the processor is further configured to automatically adjust the composition in response to the user accepting automatic adjustment.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the temporary images are pairs of color images and depth images.

### Claim 5 (depends on 4)

The device according to claim 4, wherein the reconstructed scene includes polygonal meshes or point clouds.

### Claim 6

A method for taking pictures, comprising:
capturing a plurality of temporary images of one or more subjects by using a camera;
extracting a reconstructed scene from the plurality of temporary images;
capturing a focused image of subject matter for which a user intends to take a picture by using the camera;
generating a subject map in the focused image by using the reconstructed scene;
receiving a selection of at least one of the one or more subjects from the subject map;
determining an appropriate armature from the at least one of the one or more subjects selected from the subject map;
combining the armature with focused image;
determining that the composition of the focused image can be improved; and
presenting an instruction to the user to adjust the composition through an interface on a display.

### Claim 7 (depends on 6)

A non-transitory storage media storing computer executable instructions thereon which, when executed by a processor, causes the processor to perform the method according to claim 6.
