Abstract

A mobile terminal including a camera configured to obtain an image; a display configured to display the obtained image; and a controller configured to receive a zoom input for zooming in on the displayed image, display a zoomed image on a portion of the displayed image in response to the zoom input, and capture at least one of the displayed image and the zoomed image in response to a predetermined input.

First claim

What is claimed is:

1. A mobile terminal comprising:
a camera configured to obtain an image;
a display configured to display the obtained image; and
a controller configured to:
display guide lines respectively corresponding to predetermined zoom magnification levels on the displayed image, when receiving a zoom input for zooming in on the displayed image,
receive a selection of any one of the guide lines,
zoom and display a portion of the obtained image according to a zoom magnification level of the selected guide line, and
capture at least one of the displayed image and the zoomed image in response to a predetermined input,
wherein the controller is further configured to:
store the obtained image as a moving image,
in response to a changing of a zoom magnification while storing the moving image, store information about the changed zoom magnification along with the stored moving image, and
display a graphic object including information about the changed zoom magnification in response to an image corresponding to a time when the zoom magnification is changed being reproduced while reproducing the stored moving image.

2. The mobile terminal of claim 1 , wherein the controller is further configured to activate one of the displayed image and the zoomed image, deactivate the other one of the displayed image and the zoomed image and store the activated image in a memory in response to a selection of the user.

3. The mobile terminal of claim 2 , wherein the controller is further configured to distinctively display the activated image and the deactivated image from each other on the display using at least one of colors and sharpness of the displayed images and a graphic object displayed near a region of the displayed images.

4. The mobile terminal of claim 1 , wherein the controller is further configured to:
zoom in a partial region of the displayed image with respect to the zoom input, and
display the zoomed image on a predetermined region of the display provided with respect to the zoom input.

5. The mobile terminal of claim 4 , wherein the controller is further configured to determine a size of the predetermined region based on a zoom-in or zoom-out magnification according to the zoom input.

6. The mobile terminal of claim 1 , wherein the zoomed image comprises a plurality of images zoomed in or out at different magnifications, and
wherein the controller is further configured to store the plurality of images in a memory, in an order selected by a user.

7. The mobile terminal of claim 6 , wherein the controller is further configured to:
create a moving image including the plurality of images, and
sequentially display the plurality of images included in the moving image in the selected order on the display.

8. The mobile terminal of claim 7 , wherein the controller is further configured to display a thumbnail image corresponding to the moving image, and
wherein the thumbnail image comprises information about a number of the plurality of images included in the moving image.

9. The mobile terminal of claim 1 , wherein the controller is further configured to zoom the displayed image according to a zoom magnification corresponding to a selected corresponding guide line.

10. The mobile terminal of claim 1 , wherein the controller is further configured to limit a zoom-in operation or a zoom-out operation performed based on a zoom magnification higher than the zoom magnification corresponding to the selected guide line, or limit the zoom-in operation or the zoom-out operation performed based a zoom magnification lower than the zoom magnification corresponding to the selected guide line.

11. The mobile terminal of claim 1 , wherein the information about the changed zoom magnification comprises a magnification at which a zoom-in operation or a zoom-out operation is performed, a time when a user input for performing the zoom-in operation or the zoom-out operation is received, and information of one point of the display to which a touch input corresponding to the zoom-in operation or the zoom-out operation is applied.

12. The mobile terminal of claim 1 , wherein the controller is further configured to display an image, which is zoomed in or out at the changed zoom magnification, on at least a portion of the display in which the stored moving image is reproduced, based on a selection of the graphic object.

13. The mobile terminal of claim 1 , wherein the camera is further configured to sense an image of a specific subject in the obtained image, and
wherein the controller is further configured to select a zoom magnification, based on a moving speed of the specific subject and display an image, which is zoomed in or out at the determined zoom magnification, on a portion of the display.

14. The mobile terminal of claim 13 , wherein the controller is further configured to perform the zoom-in operation or the zoom-out operation according to a distance between the camera and the specific subject being changed.

15. The mobile terminal of claim 1 , wherein the controller is further configured to:
in response to a predetermined peripheral device being connected to the mobile terminal, display the zoomed image on the connected peripheral device instead of the display, based on a user touch input sensed through the peripheral device, and
store the displayed image, based on a user input sensed through the peripheral device.

16. A method of controlling a mobile terminal, the method comprising:
obtaining, via a camera of the mobile terminal, an image;
displaying, via a display of the mobile terminal, the obtained image;
receiving, via a controller of the mobile terminal, a zoom input for zooming in on the displayed image;
displaying guide lines respectively corresponding to predetermined zoom magnification levels on the displayed image;
receiving a selection of any one of the guide lines;
zooming and displaying, via the display, a portion of the obtained image according to a zoom magnification level of the selected guide line;
capturing, via the camera, at least one of the displayed image and the zoomed image in response to a predetermined input;
storing the obtained image as a moving image;
storing information about the changed zoom magnification along with the stored moving image, in response to a changing of a zoom magnification while storing the moving image; and
displaying a graphic object including information about the changed zoom magnification in response to an image corresponding to a time when the zoom magnification is changed being reproduced while reproducing the stored moving image.
