Abstract

An electronic apparatus, a method of controlling the same, and a non-transitory computer-readable storage medium are provided. The method includes: detecting an inclination of the electronic apparatus; recognizing a gesture command from an input image by taking into consideration the inclination of the electronic apparatus; and controlling the electronic apparatus to perform an operation according to the recognized gesture command.

Claims

1. A method of controlling an electronic apparatus, the method comprising:

detecting an inclination of the electronic apparatus;

recognizing a gesture command from an input image by taking into consideration the inclination of the electronic apparatus; and

controlling the electronic apparatus to perform an operation according to the recognized gesture command.

2. The method of claim 1, wherein the recognizing of the gesture command comprises:

rotating the input image according to the inclination of the electronic apparatus; and

recognizing the gesture command from the rotated input image.

3. The method of claim 1, wherein the recognizing of the gesture command comprises:

recognizing the gesture command by changing a direction of a previously defined gesture command according to the inclination of the electronic apparatus.

4. The method of claim 1, wherein the detecting of the inclination of the electronic apparatus comprises:

detecting the inclination of the electronic apparatus using face detection information of a subject of the input image.

5. The method of claim 1, further comprising:

generating a live view from the input image by taking into consideration a rotation state of a display unit rotatably installed on the electronic apparatus and the inclination of the electronic apparatus; and

displaying information regarding the recognized gesture command on the live view,

wherein the displaying of the information comprises;

determining a display direction of the recognized gesture command according to the rotation state of the display unit and the inclination of the electronic apparatus, and

displaying the information regarding the recognized gesture command.

6. The method of claim 1, further comprising:

providing feedback when the gesture command is recognized from the input image.

7. An electronic apparatus comprising:

a photographing unit that performs photoelectric conversion on incident light and generates an input image;

an inclination detecting unit that detects an inclination of the electronic apparatus;

a gesture recognizing unit that recognizes a gesture command from the input image by taking into consideration the inclination of the electronic apparatus; and

a control unit that controls the electronic apparatus to perform an operation according to the recognized gesture command.

8. The electronic apparatus of claim 7, wherein the gesture recognizing unit rotates the input image according to the inclination of the electronic apparatus, and recognizes the gesture command from the rotated input image.

9. The electronic apparatus of claim 7, wherein the gesture recognizing unit recognizes the gesture command by changing a direction of a previously defined gesture command according to the inclination of the electronic apparatus.

10. The electronic apparatus of claim 7, wherein the inclination detecting unit detects the inclination of the electronic apparatus using face detection information of a subject of the input image.

11. The electronic apparatus of claim 7, further comprising:

a live view generating unit that generates a live view from the input image by taking into consideration a rotation state of a display unit rotatably installed on the electronic apparatus and the inclination of the electronic apparatus;

a gesture information generating unit that provides information regarding the recognized gesture command on the live view; and

the display unit displays the live view and the information regarding the recognized gesture command,

wherein the gesture information generating unit determines a display direction of the recognized gesture command according to the rotation state of the display unit and the inclination of the electronic apparatus, and the display unit displays the information regarding the recognized gesture command.

12. The electronic apparatus of claim 7, further comprising:

a feedback providing unit that provides feedback when the gesture command is recognized from the input image.

13. A non-transitory computer-readable storage medium having embodied thereon a program for executing a method of controlling an electronic apparatus when the program is read and executed by a processor, wherein the method comprises:

detecting an inclination of the electronic apparatus;

recognizing a gesture command from an input image by taking into consideration the inclination of the electronic apparatus; and

controlling the electronic apparatus to perform an operation according to the recognized gesture command.

14. The non-transitory computer-readable storage medium of claim 13, wherein the recognizing of the gesture command comprises:

rotating the input image according to the inclination of the electronic apparatus; and

recognizing the gesture command from the rotated input image.

15. The non-transitory computer-readable storage medium of claim 13, wherein the recognizing of the gesture command comprises:

recognizing the gesture command by changing a direction of a previously defined gesture command according to the inclination of the electronic apparatus.

16. The non-transitory computer-readable storage medium of claim 13, wherein the detecting of the inclination of the electronic apparatus comprises:

detecting the inclination of the electronic apparatus using face detection information of a subject of the input image.

17. The non-transitory computer-readable storage medium of claim 13, wherein the method further comprises:

generating a live view from the input image by taking into consideration a rotation state of a display unit rotatably installed on the electronic apparatus and the inclination of the electronic apparatus; and

displaying information regarding the recognized gesture command on the live view,

wherein the displaying of the information comprises;

determining a display direction of the recognized gesture command according to the rotation state of the display unit and the inclination of the electronic apparatus, and

displaying the information regarding the recognized gesture command.

18. The non-transitory computer-readable storage medium of claim 13, wherein the method further comprises:

providing feedback when the gesture command is recognized from the input image.
