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 operable to receive a user input to select an image movement direction and an image movement speed;

a storage configured to store a plurality of images;

a display; and

a controller which is operable to control the display to display a first image among the plurality of images on a screen area such that a horizontal width of the displayed first image fits within a horizontal width of the screen area while maintaining an aspect ratio of the displayed first image being different from the aspect ratio of the screen area and a displayed portion of the displayed first image automatically moves in the selected image movement direction and at the selected image movement speed,

wherein the controller controls the display to display a boundary effect between the first image and a second image among the plurality of images, the second image being an image to be displayed following the first image.

2. The image displaying apparatus of claim 1, further comprising a receiver which receives the image from an image source.

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

4. The image displaying apparatus of claim 1, wherein the controller extends the image until the horizontal width of the image becomes identical to the horizontal width of the screen area.

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

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

7. The image displaying apparatus of claim 1, wherein the boundary effect comprises a blurring effect.

8. The image displaying apparatus of claim 1, wherein the user input 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, the controller stores the captured image.

9. 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.

10. The image displaying apparatus of claim 9, wherein the controller is configured to receive a user input via the touch panel to input the movement direction of the respective image displayed in the screen area.

11. The image displaying apparatus of claim 10, wherein the image is resized such that the horizontal width of the image equals an entire horizontal 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.

12. The image displaying apparatus of claim 9, 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 screen area.

13. An apparatus comprising:

a storage configured to store a plurality of images;

a touch display operable to receive a user input to select an image movement speed and an image movement direction; and

a controller which is operable control the touch display to display a first image among the plurality of images on a screen area such that a horizontal width of the displayed first image fits within a horizontal width of the screen area while maintaining an aspect ratio of the displayed first image being different from the aspect ratio of the screen area and a displayed portion of the displayed first image automatically moves in the selected image movement direction and at the selected image movement speed,

wherein the controller controls the touch display to display a boundary effect between the first image and a second image among the plurality of images, the second image being an image to be displayed following the first image.

14. The apparatus of claim 13, wherein the controller is operable to receive a third user input via the touch display to zoom in or zoom out the image displayed in the screen area.

15. A non-transitory computer readable medium having computer-executable instructions stored thereon, which, when executed by an apparatus having a touch display and storing a plurality of images, causes the apparatus to perform a method comprising:

receiving a user input, via the touch display, to select an image movement speed and an image movement direction;

displaying a first image among the plurality of images on a screen area of the touch display such that a horizontal width of the displayed first image fits within a horizontal width of the screen area, while maintaining an aspect ratio of the displayed first image being different from the aspect ratio of the screen area;

automatically moving a displayed portion of the displayed first image in the selected image movement direction and at the image movement speed; and

displaying a boundary effect between the first image and a second image among the plurality of images, the second image being an image to be displayed following the first image.

16. The non-transitory computer readable medium of claim 15, wherein the method further comprises:

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