Abstract

A method and an apparatus for recognizing a specific object inside an image in an electronic device are provided. The method includes displaying at least one image; detecting at least one gesture; selecting a recognition function related to at least one object existing in the at least one image according to the detected at least one gesture; and recognizing the at least one object using the selected recognition function.

Claims

1. A method for recognizing a specific object inside an image in an electronic device, the method comprising:

displaying at least one image;

detecting at least one gesture;

selecting a recognition function related to at least one object existing in the at least one image according to the detected at least one gesture; and

recognizing the at least one object using the selected recognition function.

2. The method of claim 1, wherein the recognition function includes at least one of character recognition, barcode recognition, face recognition, and two-dimensional image code recognition.

3. The method of claim 1, wherein selecting the recognition function related to the at least one object existing in the at least one image according to the detected at least one gesture comprises:

designating at least one object region in the at least one image according to a first gesture; and

selecting an object recognition module for analyzing the object region according to a second gesture.

4. The method of claim 3, wherein the object region is selected by a predetermined region determination reference based on position information of a location where the first gesture has been input or a pattern of the first gesture.

5. The method of claim 4, wherein the predetermined region determination reference includes at least one of a size of an object inside the image, a distance between an image-pick up device and the object, a position, pattern density, brightness, and a length of an edge.

6. The method of claim 3, wherein the second gesture is mapped to a specific object recognition module.

7. The method of claim 3, further comprising:

performing focusing using the designated at least one object region as a reference.

8. The method of claim 3, further comprising:

adjusting at least one of brightness, sharpness, contrast, and an exposure time using the designated at least one object region as a reference to enhance image quality.

9. The method of claim 3, further comprising:

displaying a user interface informing that the at least one object region has been designated; and

tracking a position of the designated at least one object region.

10. The method of claim 1, wherein selecting the recognition function related to the at least one object existing in the at least one image according to the detected at least one gesture comprises:

designating at least one object region in the at least one image based on position information of a location where the at detected at least one gesture has been input or a pattern of the detected at least one gesture; and

selecting an object recognition module for analyzing the designated at least one object region.

11. The method of claim 10, wherein selecting the object recognition module for analyzing the designated at least one object region comprises:

analyzing a pattern of an object corresponding to a pattern path of the detected at least one gesture on the designated at least one object region; and

selecting an object recognition module corresponding to the analyzed pattern.

12. The method of claim 10, wherein designating the at least one object region comprises:

analyzing a pattern of an object corresponding to a pattern path of the gesture on the designated at least one object region; and

inferring a direction, a slope, or a region of an object corresponding to the analyzed pattern.

13. The method of claim 10, wherein selecting the object recognition module for analyzing the designated at least one object region comprises:

selecting an object recognition module corresponding to a pattern of the gesture on the designated at least one object region.

14. The method of claim 1, further comprising, before recognizing the at least one object:

displaying a list of recognition functions related to the at least one object; and

selecting one function from the displayed list of recognition functions.

15. The method of claim 1, further comprising:

displaying, after recognizing the at least one object, displaying results of the recognition;

or

displaying a list of at least one application related to the recognition results.

16. An electronic device comprising:

at least one processor; and

at least one memory,

wherein the processor comprises instructions configured to display at least one image, detect at least one gesture, select a recognition function related to at least one object existing in the at least one image according to the detected at least one gesture, and recognize the at least one object using the selected recognition function.

17. The electronic device of claim 16, wherein the recognition function includes at least one of character recognition, barcode recognition, face recognition, and two-dimensional image code recognition.

18. The electronic device of claim 16, wherein the instruction configured to select the recognition function related to the at least one object existing in the at least one image according to the detected at least one gesture comprises:

an instruction configured to designate at least one object region in the at least one image according to a first gesture, and

select an object recognition module configured to analyze the object region according to a second gesture.

19. The electronic device of claim 18, wherein the object region is selected by a predetermined region determination reference based on position information of a location where the first gesture has been input or a pattern of the first gesture.

20. The electronic device of claim 19, wherein the predetermined region determination reference includes at least one of a size of an object inside the image, a distance between an image-pick up device and the object, a position, pattern density, brightness, and a length of an edge.

21. The electronic device of claim 18, wherein the second gesture is mapped to a specific object recognition module.

22. The electronic device of claim 18, wherein the processor further comprises an instruction configured to perform focusing using the designated at least one object region as a reference.

23. The electronic device of claim 18, wherein the processor further comprises an instruction configured to adjust at least one of brightness, sharpness, contrast, and an exposure time using the designated at least one object region as a reference to enhance image quality.

24. The electronic device of claim 16, wherein the instruction configured to select the recognition function related to the at least one object existing in the at least one image according to the gesture comprises:

an instruction configured to designate at least one object region in the at least one image based on position information of a location where the detected at least one gesture has been input or a pattern of the gesture, and

select an object recognition module configured to analyze the designated at least one object region.

25. The electronic device of claim 24, wherein selecting the object recognition module configured to analyze the designated object region includes selecting an object recognition module corresponding to a pattern of the detected at least one gesture on the designated at least one object region.

26. The electronic device of claim 16, wherein the processor further comprises:

an instruction configured to display, before recognizing the at least one object, a list of recognition functions related to the at least one object, and
