Abstract

A method for photographing a portrait in an apparatus having a camera is provided. The method includes detecting a person in an image obtained by a camera in a photographing mode, determining occurrence of an error by identifying whether the detected person is located in a subject recognition area, generating an error warning including direction information so that the person moves into the subject recognition area if at least a portion of the person is out of the subject recognition area based on the determining of the occurrence of the error, and storing an image output by the camera if the person is located in the subject recognition area based on the determining of the occurrence of the error.

First claim

What is claimed is:

1. A method for photographing a portrait in an apparatus having a camera, the method comprising:
setting the apparatus in a photographing mode in response to a turn-over operation being detected by the apparatus;
detecting a person in an image obtained by the camera in the photographing mode;
determining an occurrence of an error by identifying whether the detected person is located in a subject recognition area that is automatically set based on a type of the photographing mode;
generating an error warning including direction information directing the person to move into the subject recognition area if at least a portion of the person is determined to be out of the subject recognition area based on the determining of the occurrence of the error; and
storing an image output by the camera if the person is determined to be located in the subject recognition area based on the determining of the occurrence of the error.

2. The method of claim 1 ,
wherein the photographing mode comprises a portrait photographing mode outputting a voice as the error warning, which is set according to an error type in a setting mode, and
wherein the portrait photographing mode is set before or after an activation of the camera to obtain the image.

3. The method of claim 2 , wherein the generating of the error warning comprises:
analyzing the error type regarding the person in the subject recognition area; and
generating the error warning by guiding the error warning with the voice corresponding to the error type.

4. The method of claim 3 ,
wherein the error type includes at least one of:
the person being out of the subject recognition area in an upward direction,
the person being out of the subject recognition area in a downward direction,
the person being out of the subject recognition area in a leftward direction, and
the person being out of the subject recognition area in a rightward direction, and

wherein the generating of the error warning comprises generating a voice error warning including the direction information directing the person to move in an appropriate direction so as to be located in the subject recognition area, the direction information corresponding to the error type.

5. The method of claim 3 ,
wherein the error type comprises an error in which the person is located too far from the subject recognition area, and
wherein the generating of the error warning generates a voice error warning including the direction information directing the person to reduce a distance between the person and the apparatus.

6. The method of claim 3 ,
wherein the determining of the occurrence of the error further comprises determining a horizontal level of the apparatus through a sensor, and
wherein the generating of the error warning comprises generating a voice error warning including the direction information directing the camera to adjust a level of the apparatus so that the apparatus maintains a horizontal state, if the horizontal level of the apparatus is inclined.

7. The method of claim 3 ,
wherein the error type comprises an error in which a face area of the person is not detected in the subject recognition area, and
wherein the generating of the error warning comprises generating a voice error warning indicating that the face area is not detected according to the error type.

8. The method of claim 3 ,
wherein the error type comprises an error in which eyes of the person in the subject recognition area are closed, and
wherein the generating of the error warning comprises generating a voice error warning indicating that the eyes of the person are closed according to the error type.

9. The method of claim 3 , wherein the detecting of the person in the image further comprises outputting a voice indicating a number of detected persons.

10. An apparatus having a camera, the apparatus comprising:
a display unit disposed on a side of the camera and configured to display an image photographed by the camera;
a storage unit configured to:
store error warnings corresponding to error types, and
store photographed images; and

a control unit configured to:
set the apparatus in a photographing mode in response to a turn-over operation being detected by the apparatus;
detect a person in an image obtained by the camera in the photographing mode;
determine an occurrence of an error by identifying whether the person is located in a subject recognition area of the image output by the camera in the photographing mode, the subject recognition area being automatically set based on a type of the photographing mode,
generate an error warning including direction information directing the person to move into the subject recognition area if at least a portion of the person is determined to not be located in the subject recognition area based on the determined occurrence of the error, and
store the image output by the camera if the person is determined to be located in the subject recognition area based on the determined occurrence of the error.

11. The apparatus of claim 10 ,
wherein the storage unit is further configured to store voice error warnings, and
wherein the control unit is further configured to set a portrait photographing mode generating a voice error warning from the error warning in a setting mode.

12. The apparatus of claim 11 , wherein the control unit is configured to:
determine an error type of the person in the subject recognition area of the image obtained by the camera, and
output a voice error warning stored in the storage unit corresponding to the error type as a voice.

13. The apparatus of claim 12 , wherein the control unit is further configured to:
determine the error type by identifying whether the person is out of the subject recognition area in at least one of an upward direction, a downward direction, a leftward direction, and a rightward direction, and
generate the voice error warning including the direction information directing the person to move in an appropriate direction so as to be located in the subject recognition area, the direction information corresponding to the determined error type.

14. The apparatus of claim 13 , further comprising:
a sensor configured to detect a horizontal level of the apparatus,
wherein the control unit is further configured to generate the voice error warning including the direction information by analyzing the output of the sensor and directing the apparatus to adjust a level of the apparatus so that the apparatus maintains a horizontal state, if the horizontal level of the apparatus is inclined.

15. The apparatus of claim 14 ,
wherein the apparatus comprises a portable terminal, and
wherein the portrait photographing mode is set in an auto-portrait mode.

16. An apparatus comprising:
a camera disposed on a first side of the apparatus and configured to operate in a photographing mode and capture an image;
a display unit disposed on a second side of the apparatus, opposite the first side, and configured to display the image captured by the camera;
a storage unit configured to:
store error warnings corresponding to error types, and
store the image captured by the camera; and

a control unit configured to:
set the apparatus in a photographing mode in response to a turn-over operation being detected by the apparatus;
detect a person in the image captured by the camera in the photographing mode;
determine an occurrence of an error by identifying whether the person is located in a subject recognition area of the image captured by the camera when the camera operates in the photogr
