Abstract

An electronic device is provided. The electronic device includes a camera module, a memory configured to store reference composition information, and a camera control module configured to collect real-time composition information through the camera module. The camera control module compares the stored reference composition information and the real-time composition information to indicate to a user whether the stored reference composition information and the real-time composition information are consistent with each other.

Claims

1. An electronic device comprising:

a camera;

a display;

movement sensors configured to recognize movement of the electronic device;

a memory configured to store reference composition information and instructions; and

at least one processor,

wherein the at least one processor is configured to;

display a user interface on the display for selecting a type of composition adjustment message among a plurality of types of composition adjustment message,

receive a user input for selecting the type of composition adjustment message via the user interface, capture a specific picture or video using the camera,

extract real-time composition information from the specific picture or video, and the movement sensors,

compare the stored reference composition information to the real-time composition information, and

output the composition adjustment message of the type selected by the user input, when a hit ratio of the real-time composition information to the stored reference composition information is smaller than a reference value.

2. The electronic device of claim 1, wherein the stored reference composition information is predetermined by at least one of a user, a manufacturing company, or a service provider.

3. The electronic device of claim 1, wherein the reference composition information is extracted from another specific picture or video.

4. The electronic device of claim 3, further comprising a sub camera, the sub camera being independently implemented from the camera.

5. The electronic device of claim 4, wherein the at least one of the specific picture or video is captured using one of the camera or the sub camera.

6. The electronic device of claim 5, wherein the sub camera is disposed on the same surface as that of a display of the electronic device.

7. The electronic device of claim 1, wherein the stored reference composition information comprises at least one of information on a state of the electronic device or digital image information included in a specific image.

8. The electronic device of claim 7, wherein the information on the state of the electronic device comprises information on a movement direction, a tilt or an azimuth of the electronic device recognized through a sensor.

9. The electronic device of claim 7, wherein the digital image information comprises information on brightness or chroma of a specific point of the specific picture or video.

10. The electronic device of claim 7, wherein the digital image information comprises information on a portion of the specific picture or video.

11. The electronic device of claim 1, wherein the real-time composition information comprises at least one of information on a state of the electronic device and digital image information of the specific picture or video captured using the camera.

12. The electronic device of claim 1, wherein the at least one processor is further configured to compare information on a state of the electronic device included in the real-time composition information to information on a state of the electronic device included in the stored reference composition information.

13. The electronic device of claim 1, wherein the at least one processor is further configured to compare a picture or video associated with the stored reference composition information to the specific picture or video captured using the camera.

14. The electronic device of claim 1, wherein the at least one processor is further configured to output a composition hit message or perform auto-shooting, when a hit ratio of the real-time composition information to the stored reference composition information is greater than or equal to a reference value.

15. A shooting method executed by an electronic device having movement sensors and at least one processor, the shooting method comprising:

displaying a user interface on a display for selecting a type of composition adjustment message among a plurality of types of composition adjustment message;

receiving a user input for selecting the type of composition adjustment message via the user interface;

storing reference composition information in a memory;

capturing a specific picture or video using a camera;

extracting, using the one or more processors, real-time composition information from the specific picture or video and the movement sensors;

comparing the stored reference composition information to the real-time composition information; and

outputting the composition adjustment message of the type selected by the user input, when a hit ratio of the real-time composition information to the stored reference composition information is smaller than a reference value.

16. The shooting method of claim 15, wherein the storing of the reference composition information comprises:

extracting the reference composition information from another picture or video captured using a sub camera; and

storing the extracted reference composition information at the memory.

17. The shooting method of claim 15,

wherein the indicating to the user comprises outputting a composition hit message or performing auto-shooting, and

wherein a hit ratio of the real-time composition information compared to the reference composition information is greater than or equal to a specific reference value.
