Digital photographing apparatus, method of controlling the same, and recording medium storing a program for implementing the method

1. A method of controlling a digital photographing apparatus, the method comprising:

determining a motion direction of the digital photographing apparatus by analyzing image data obtained from light incident on an imaging device; and

switching from a first mode of the digital photographing apparatus to a second mode based on the determined motion direction, wherein the first and second modes are different ones selected from a group consisting of a photographing mode, a playback mode, an operating environment setting mode, and a shutdown mode.

2. The method of claim 1 , further comprising switching the first mode to the second mode based on the determined motion direction when an amount of motion corresponding to the determined motion direction is larger than a threshold.

3. The method of claim 1 , further comprising blocking the light from being incident on the imaging device when the digital photographing apparatus does not move during a period of time.

4. The method of claim 1 , further comprising not obtaining the image data from the light when the digital photographing apparatus does not move during a period of time.

5. A method of controlling a digital photographing apparatus in a playback mode, the method comprising:

determining a motion direction of the digital photographing apparatus by analyzing image data obtained from light incident on an imaging device; and

switching a number of images displayed on the display unit to a different number of non-overlapping images when the determined motion direction comprises a first direction.

6. The method of claim 5 , wherein the switching of a number of images comprises, if a single image is displayed on the display unit, switching from the single image to a plurality of images in accordance with the motion of the first direction and, if the plurality of images are displayed on the display unit, switching from the plurality of images to a single image in accordance with the motion of the first direction.

7. The method of claim 5 , further comprising switching the display when an amount of motion corresponding to the determined motion direction is larger than a threshold and the determined motion direction comprises the first direction.

8. The method of claim 5 , further comprising blocking the light from being incident on the imaging device when the digital photographing apparatus does not move during a period of time.

9. The method of claim 5 , further comprising not obtaining the image data from the light when the digital photographing apparatus does not move during a period of time.

10. A non-transitory recording medium having recorded thereon a computer program for executing at least the method of claim 5 .

11. A digital photographing apparatus comprising:

an imaging device to form image data from light incident on the imaging device; and

a processing unit to switch the digital photographing apparatus from a first mode to a second mode based on a motion direction determined by analyzing the image data, wherein the first and second modes are different ones selected from a group consisting of a photographing mode, a playback mode an operating environment setting mode and a shutdown mode.

12. The digital photographing apparatus of claim 11 , wherein the processing unit is to switch the first mode to the second mode based on the determined motion direction when an amount of motion corresponding to the motion direction is larger than a threshold.

13. The digital photographing apparatus of claim 11 , wherein the processing unit is to block the light from being incident on the imaging device when the digital photographing apparatus does not move during a period of time.

14. The digital photographing apparatus of claim 11 , wherein the imaging device does not form the image data from the light when the digital photographing apparatus does not move during a period of time.

15. The digital photographing apparatus of claim 11 , further comprising a computer-readable medium storing machine-readable instructions that, when executed, cause the processing unit to at least switch the digital photographing apparatus from the first mode to the second mode based on the determined motion direction.

16. A digital photographing apparatus comprising:

an imaging device to form image data from light incident on the imaging device; and

a processing unit to:

determine a motion direction of the digital photographing apparatus by analyzing the image data; and

switch a number of images displayed on a display unit of the digital photographing apparatus in a playback mode to a different number of non-overlapping images, when the determined motion direction comprises a first direction.

17. The digital photographing apparatus of claim 16 , wherein, if a single image is displayed on the display unit, the processing unit is to switch from the single image to a plurality of images in accordance with the motion of the first direction and, if the plurality of images are displayed on the display unit, the processing unit is to switch from the plurality of images to a single image in accordance with the motion of the first direction.

18. The digital photographing apparatus of claim 16 , wherein the processing unit is to switch the display of the first plurality of images when an amount of motion corresponding to the determined motion direction is larger than a threshold and the determined motion direction comprises the first direction.

19. The digital photographing apparatus of claim 1 , wherein the processing unit is to block the light from being incident on the imaging device when the digital photographing apparatus does not move during a period of time.

20. The digital photographing apparatus of claim 16 , wherein the imaging device is not to form the image data from the light when the digital photographing apparatus does not move during a period of time.

21. The digital photographing apparatus of claim 16 , further comprising a computer-readable medium storing machine-readable instructions that, when executed, cause the processing unit to at least switch the display of the first plurality of images to the display of the first image when the determined motion direction comprises the first direction.
