Abstract

An image displaying apparatus is provided, which includes: a display unit that displays an image, and which has a horizontal width and a vertical width; an image processing unit which processes the image; and a controller which controls the image processing unit, if an aspect ratio of the image is different from an aspect ratio of the display unit, to extend the image in a first direction until a horizontal width or a vertical width of the image becomes identical to any one of the horizontal width and the vertical width of the display unit, to extend the image in a second direction to maintain the aspect ratio of the image, and to move the extended image in the second direction on the display unit.

Claims

1. An image displaying apparatus, comprising:

a display unit that displays an image, and which has a horizontal width and a vertical width;

an image processing unit which processes the image; and

a controller which controls the image processing unit, if an aspect ratio of the image is different from an aspect ratio of the display unit, to extend the image in a first direction until a horizontal width or a vertical width of the image becomes identical to one of the horizontal width and the vertical width of the display unit, to extend the image in a second direction to maintain the aspect ratio of the image, and to move the extended image in the second direction on the display unit.

2. The image displaying apparatus of claim 1, further comprising a receiving unit which receives the image to be processed by the image processing unit from an image source.

3. The image displaying apparatus of claim 1, further comprising a storage unit that stores the image to be processed by the image processing unit.

4. The image displaying apparatus of claim 1, wherein the display unit is rectangular in shape.

5. The image displaying apparatus of claim 1, wherein if a ratio of the horizontal width to the vertical width of the image is smaller than a ratio of the horizontal width to the vertical width of the display unit, the image processing unit extends the image until the horizontal width of the image becomes identical to the horizontal width of the display unit.

6. The image displaying apparatus of claim 5, wherein the image is moved in a vertical direction.

7. The image displaying apparatus of claim 1, wherein if a ratio of the horizontal width to the vertical width of the image is larger than a ratio of the horizontal width to the vertical width of the display unit, the image processing unit extends the image until the vertical width of the image becomes identical to the vertical width of the display unit.

8. The image displaying apparatus of claim 5, wherein the image is moved in a horizontal direction.

9. The image displaying apparatus of claim 1, wherein the controller controls the image processing unit to display a zoom in process on the display unit whereby the image is extended before movement, and a zoom out process whereby the image is contracted after movement.

10. The image displaying apparatus of claim 1, wherein the controller controls the image processing unit to process a plurality of images and make boundaries between the plurality of images.

11. The image displaying apparatus of claim 10, wherein at least one of the boundaries is blurry.

12. The image displaying apparatus of claim 1, further comprising a user selection unit that receives selection of a movement direction of the image.

13. The image displaying apparatus of claim 1, further comprising a user selection unit that captures at least a portion of an image being displayed while the image is being moved,

wherein if an image is captured through the user selection unit, the controller stores the captured image.

14. An image displaying apparatus, comprising:

a display unit which has a horizontal width and a vertical width;

an image processing unit which processes a plurality of images; and

a controller which controls the image processing unit to adjust the plurality of images in a first direction to make the horizontal width or the vertical width of a received image identical to any one of the horizontal width and the vertical width of the display unit, to connect boundaries of the adjusted plurality of images, and to move the connected plural images in a second direction on the display unit.

15. The image displaying apparatus of claim 14, wherein the controller controls the image processing unit to make boundaries between the plurality of images blurry.

16. An image displaying method of an image displaying apparatus including a display unit having a horizontal width and a vertical width, comprising:

receiving an image from an image source;

if an aspect ratio of the image is different from an aspect ratio of the display unit, extending the image to make a horizontal width or a vertical width of the received image identical to any one of the horizontal width or the vertical width of the display unit, extending the image in a second direction to maintain the aspect ratio of the image; and

moving the extended image in the second direction on the display unit.

17. The image displaying method of claim 16, wherein the extending the image extends the image to make the horizontal width of the image identical to the horizontal width of the display unit if a ratio of the horizontal width to the vertical width of the image is smaller than a ratio of the horizontal width to the vertical width of the display unit.

18. The image displaying method of claim 17, wherein the image is moved in a vertical direction.

19. The image displaying method of claim 16, wherein the extending the image extends the image to make the vertical width of the image identical to the vertical width of the display if a ratio of the horizontal width to the vertical width of the image is larger than a ratio of the horizontal width to the vertical width of the display unit.

20. The image displaying method of claim 16, wherein the image is moved in a horizontal direction.

21. The image displaying method of claim 16, further comprising displaying a zoom in process to extend the image before movement and displaying a zoom out process to reduce the image after movement.

22. The image displaying method of claim 16, further comprising processing a plurality of images to make boundaries between the plurality of images blurry.

23. The image displaying method of claim 16, further comprising:

receiving a user selection signal to capture at least a portion of the image being displayed during movement of the image; and

storing the captured image.
