Abstract

A digital photographing apparatus includes: an imaging device that generates an image signal by capturing image light; a storage unit that stores a template including a background area and a composite area that indicates at least a part of an image according to the image signal; an image changing unit that changes orientations of the template and the image; an image composing unit that composes the image and the template of which orientations are changed; and a display unit that displays the composed image, wherein the image changing unit determines orientations to be changed of the template and the image according to a rotation amount of the imaging device with respect to an optical axis of the image light and an orientation in which an imaging surface of the imaging device faces. Accordingly, a user may naturally perform a self-photography function using a template.

First claim

What is claimed is:

1. A digital photographing apparatus comprising:
an imaging device that generates an image signal by capturing image light;
a storage unit that stores a template comprising a background area and a composite area that shows at least a part of an image according to the image signal;
an image changing unit that extracts a selected template from the storage unit and changes orientations of the selected template and the image;
an image composing unit that composes the image and the template of which orientations are changed; and
a display unit that displays the composed image,
wherein the image changing unit determines orientations to be changed of the selected template and the image according to a rotation amount of the imaging device with respect to an optical axis of the image light and an orientation in which an imaging surface of the imaging device faces.

2. The digital photographing apparatus of claim 1 , wherein when the orientation in which the imaging surface faces is the same as an orientation in which the display unit faces, the image changing unit performs a horizontal symmetry change on the template and the image.

3. The digital photographing apparatus of claim 2 , wherein the image composing unit generates a photographing image obtained by composing the image and the template on which changes in orientation are not performed according to a photographing signal, and when the photographing image is reproduced at a later time in a state where the rotation amount of the imaging device and the orientation of the display unit are the same as those during a photographing operation, a 180 degrees rotational symmetry change is performed on the photographing image with respect to a center of the photographing image to display the photographing image on the display unit.

4. The digital photographing apparatus of claim 1 , wherein when the orientation in which the imaging surface faces is the same as the orientation in which the display unit faces and when the rotation amount of the imaging device is equal to or over a reference value, a horizontal symmetry change is performed on the image and a vertical symmetry change is performed on the template.

5. The digital photographing apparatus of claim 4 , wherein the image composing unit generates a photographing image obtained by composing the image on which a change in orientation is not performed with a template on which a 180 degrees rotational symmetry change is performed according to a photographing signal, and when the photographing image is reproduced at a later time in a state where the rotation amount of the imaging device and the orientation of the display unit are the same as those during a photographing operation, a 180 degrees rotational symmetry change is performed on the photographing image with respect to a center of the photographing image to display the photographing image on the display unit.

6. The digital photographing apparatus of claim 1 , wherein an upper surface of the display unit is supported by the digital photographing apparatus to rotate.

7. The digital photographing apparatus of claim 6 , wherein the display unit rotates between an orientation in which an imaging surface of the imaging device faces and an opposite orientation thereof.

8. The digital photographing apparatus of claim 7 , further comprising a position sensor that determines whether the display unit rotates at an angle equal to or over a reference angle.

9. The digital photographing apparatus of claim 1 , further comprising a movement sensor that senses a rotation amount of the imaging device with respect to the optical axis.

10. The digital photographing apparatus of claim 1 , further comprising a template determination unit that determines whether the composite area of the template has a directional property.

11. The digital photographing apparatus of claim 10 , wherein when the composite area has a directional property, the image changing unit separately performs changes in orientation on the composite area and the background area.

12. The digital photographing apparatus of claim 11 , wherein when the composite area has a directional property, the image changing unit performs a change in orientation so that the orientation of the composite area is the same as an orientation of the image.

13. The digital photographing apparatus of claim 1 , further comprising a composite area setting unit that sets a position of the composite area of the template.

14. The digital photographing apparatus of claim 1 , further comprising:
a memory that stores the image signal; and
a memory controller that controls the storage of the image signal,
wherein the memory controller changes an order of addresses storing the image signal in the memory according to the rotation amount of the imaging device with respect to the optical axis of the image light and an orientation in which the display unit faces with respect to the orientation in which the imaging surface of the imaging device faces.

15. The digital photographing apparatus of claim 14 , wherein the memory controller stores the image signal in the memory by using a direct memory access (DMA) method.

16. A method of controlling a digital photographing apparatus, the method comprising:
generating an image signal by capturing image light;
selecting a template comprising a background area and a composite area that indicates at least a part of an image according to the image signal;
changing orientations of the selected template and the image according to a movement of the digital photographing apparatus;
composing the image and the template of which orientations are changed; and
displaying the composed image.

17. The method of claim 16 , wherein the movement of the digital photographing apparatus comprises a rotation amount of an imaging device with respect to an optical axis of the image light and an orientation in which a display unit faces with respect to an orientation in which an imaging surface faces.

18. The method of claim 17 , wherein when the orientation in which the imaging surface faces is opposite to the orientation in which the display unit faces, a horizontal symmetry change is performed on the template and the image.

19. The method of claim 17 , wherein when the orientation in which the imaging surface faces is opposite to the orientation in which the display unit faces and when the rotation amount of the imaging device is equal to or over a reference value, a horizontal symmetry change is performed on the image and a vertical symmetry change is performed on the template.

20. The method of claim 17 , further comprising:
generating a photographing image obtained by composing the image and the template on which changes in orientation are not performed according to a photographing signal; and
when the photographing image is reproduced at a later time in a state where the rotation amount of the imaging device and the orientation of the display unit are the same as those during a photographing operation, performing a 180 degrees rotational symmetry change on the photographing image with respect to a center of the photographing image to display the photographing image on the display unit.
