Abstract

A method of and an apparatus for taking an image of a mobile terminal. A shooting direction of the mobile terminal is recognized. When the recognized shooting direction is not a reference direction and an image is taken, a direction of an image stored in a storage unit is matched with a direction of a preview image. Therefore, since an image displayed on a preview screen, desired by a user, is stored, additional editing of the image is not required and user convenience is improved.

Claims

1. A method of taking an image using a mobile terminal, the method comprising:

outputting a preview image for taking an image when a camera mode is activated;

recognizing a shooting direction of the mobile terminal; and

controlling a stored image to be matched with the preview image when the recognized shooting direction is different from a preset reference shooting direction.

2. The method of claim 1, wherein, in the recognition of the shooting direction, a rotating direction and a rotated angle of the mobile terminal are calculated with respect to the reference shooting direction.

3. The method of claim 2, wherein controlling a stored image to be matched with the preview image comprises:

transmitting the calculated rotating direction and rotated angle to an image signal processor encoding a shot image; and

converting, by the image signal processor, image data transmitted from a camera module based on the rotating direction and the rotated angle to encode the converted image data and to store the encoded image data as the stored image.

4. The method of claim 2, wherein controlling,a stored image to be matched with the preview image comprises:

transmitting the calculated rotating direction and rotated angle to a camera module;

converting, by the camera module, the image data based on the rotating direction and the rotated angle to transmit the converted image data to an image signal processor; and

encoding, by the image signal processor, the transmitted image data to store the encoded image data as the stored image.

5. The method of claim 2, wherein controlling a stored image to be matched with the preview image comprises:

transmitting the calculated rotating direction and rotated angle to a driving unit rotating the camera module;

rotating, by the driving unit, the camera module based on the rotating direction and the rotated angle; and

encoding the image data output from the rotated camera module to store the encoded image data as the stored image.

6. The method of claim 1, wherein, in the recognition of the shooting direction, when the mobile terminal comprises at least two displays, a determination of which display the preview image is displayed on is made.

7. The method of claim 6, wherein controlling a stored image to be matched with the preview image comprises:

searching for stored conversion information corresponding to a display on which the preview image is displayed when the preview image is displayed on a display different from a preset main display; and

converting the image data output from a camera module to store the converted image data as the stored image based on the conversion information.

8. An apparatus for taking an image at a mobile terminal comprising at least one display, the apparatus comprising:

a sensor unit configured to recognize a shooting direction of the mobile terminal;

a camera module configured to take an image;

an image signal processor configured to encode image data output from the camera module; and

a control unit configured to control a stored image to be stored the same as a preview image when the shooting direction recognized by the sensor unit is different from a preset shooting direction.

9. The apparatus of claim 8, wherein the control unit calculates a rotating direction and a rotated angle of the mobile terminal with respect to the reference shooting direction and controls the image signal processor to convert the image data based on the calculated rotating direction and rotated angle to encode the converted image data.

10. The apparatus of claim 8, wherein the control unit calculates the rotating direction and the rotated angle of the mobile terminal with respect to the reference shooting direction and transmits the calculated rotating direction and rotated angle to the camera module, and the camera module converts and outputs the image data based on the rotating direction and the rotated angle transmitted from the control unit.

11. The apparatus of claim 8, wherein the control unit calculates the rotating direction and the rotated angle of the mobile terminal with respect to the reference shooting direction;

and

the apparatus further comprises a driving unit configured to rotate the camera module based on the calculated rotating direction and rotated angle.

12. The apparatus of claim 8, wherein the sensor unit comprises at least one of a position sensor, a geomagnetic sensor, a gravity sensor, a motion sensor, a hall sensor, and a magnetic sensor.

13. The apparatus of claim 8, wherein when the display on which the preview image is displayed is different from a preset main display, the control unit converts and stores the image data output from the camera module based on conversion information mapped to the display on which the preview image is displayed and stored in advance.

14. The apparatus of claim 8, the apparatus further comprising an input unit comprising a plurality of input keys.

15. A mobile terminal configured for taking an image, the mobile terminal comprising:

at least one display; and

an imaging apparatus coupled to the at least one display, the imaging apparatus comprising;

a sensor unit configured to recognize a shooting direction of the mobile terminal;

a camera module configured to take an image;

an image signal processor configured to encode image data output from the camera module; and

a control unit configured to control a stored image to be stored the same as a preview image when the shooting direction recognized by the sensor unit is different from a preset shooting direction.

16. The mobile terminal of claim 15, wherein the control unit calculates a rotating direction and a rotated angle of the mobile terminal with respect to the reference shooting direction and controls the image signal, processor to convert the image data based on the calculated rotating direction and rotated angle to encode the converted image data.

17. The mobile terminal of claim 15, wherein the control unit calculates the rotating direction and the rotated angle of the mobile terminal with respect to the reference shooting direction and transmits the calculated rotating direction and rotated angle to the camera module, and the camera module converts and outputs the image data based on the rotating direction and the rotated angle transmitted from the control unit.

18. The mobile terminal of claim 15, wherein the control unit calculates the rotating direction and the rotated angle of the mobile terminal with respect to the reference shooting direction;

and

the imaging apparatus further comprises a driving unit configured to rotate the camera module based on the calculated rotating direction and rotated angle.

19. The mobile terminal of claim 15, wherein the sensor unit comprises at least one of a position sensor, a geomagnetic sensor, a gravity sensor, a motion sensor, a hall sensor, and a magnetic sensor.

20. The mobile terminal of claim 15, wherein when the display on which the preview image is displayed is different from a preset main display, the control unit converts and stores the image data output from the camera module based on conversion information mapped to the display on which the preview image is displayed and stored in advance.
