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 user input unit operable to receive a user input to input an image movement speed;

a display unit that displays an image on a display screen area with a horizontal width and a vertical width; and

a controller which, if an aspect ratio of the image is different from an aspect ratio of the display screen area, is operable to resize the image so that a vertical width of the image corresponds to the vertical width of the display screen area while maintaining the aspect ratio of the image and to move a displayed portion of the resized image at the inputted image movement speed to enable a non-displayed portion of the image to become visible in the display screen area.

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 the image processing unit extends the image until the vertical width of the image becomes identical to the vertical width of the display screen area.

6. The image displaying apparatus of claim 1, wherein the image is moved in a horizontal direction.

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

8. 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.

9. The image displaying apparatus of claim 8, wherein at least one of the boundaries is blurry.

10. The image displaying apparatus of claim 1, wherein the user input unit is operable to receive a user input to input a movement direction of the image.

11. The image displaying apparatus of claim 1, wherein the user input unit is operable to capture at least a portion of an image being displayed while the image is being moved,

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

12. The image displaying apparatus of claim 1, wherein the user input unit comprises a touch panel, and

the controller is configured to receive the user input via the touch panel to input the image movement speed of a respective image displayed in the display screen area.

13. The image displaying apparatus of claim 12, wherein the controller is configured to receive a user input via the touch panel to input a movement direction of the respective image displayed in the display screen area.

14. The image displaying apparatus of claim 12, wherein the controller is configured to receive a user input via the touch panel to zoom in or zoom out the respective image displayed in the display screen area.

15. The image displaying apparatus of claim 13, wherein the image is resized such that the vertical width of the image equals an entire vertical screen width of the display screen area,

if a leftward image movement direction is inputted via the user input, the controller controls display of a next image sequentially in the display screen area after a right edge portion of the image becomes visible, and

if a rightward image movement direction is inputted via the user input, the controller controls display of a next image sequentially in the display screen area after a left edge portion of the image becomes visible.

16. An apparatus comprising:

an image processing unit configured to process an image;

a touch display unit having a display screen area with a horizontal width and a vertical width to display an image processed by the image processor unit, the touch display unit operable to receive a first user input to input a movement speed of a respective image displayed in the display screen area; and

a controller which, if an aspect ratio of the image is different from an aspect ratio of the display screen area, is operable to resize the image so that a vertical width of the image corresponds to the vertical width of the display screen area while maintaining the aspect ratio of the image and to move a displayed portion of the resized image at the inputted image movement speed to enable a non-displayed portion of the image to become visible in the display screen area.

17. The apparatus of claim 16, wherein the controller is operable to receive a second user input via the touch display unit to input a movement direction of the respective image displayed in the display screen area.

18. The apparatus of claim 16, wherein the controller is operable to receive a third user input via the touch display unit to zoom in or zoom out the respective image displayed in the display screen area.

19. A non-transitory computer readable medium having computer-executable instructions stored thereon, which, when executed by an apparatus having a touch display unit, causes the apparatus to perform a method comprising:

receiving a user input, via the touch display unit, to input a movement speed for an image;

if an aspect ratio of the image is different from an aspect ratio of a display screen area of the touch display unit, resizing the image to make a vertical width thereof to correspond to a vertical width of the display screen area, while maintaining the aspect ratio of the image; and

moving a displayed portion of the resized image at the movement speed set to enable a non-displayed portion of the image to become visible in the display screen area.

20. The non-transitory computer readable medium of claim 19, wherein the method further comprises:

receiving a user input via the touch display unit to input a movement direction of a respective image to be displayed in the display screen area.

21. The non-transitory computer readable medium of claim 19, wherein the method further comprises:

receiving a user input via the touch display unit to zoom in or zoom out a respective image to be displayed in the display screen area.
