Abstract

A mobile terminal and controlling method thereof are disclosed, which facilitates a terminal to be used in further consideration of user'"'"'s convenience. The present invention includes a display, a memory configured to store at least one image fragment, a 1^st camera, and a controller, if the 1^st camera is activated, displaying a preview screen of an image received from the 1^st camera, the controller controlling the display to display a prescribed one of the stored at least one image fragment on a prescribed region of the preview screen. Accordingly, when a photo is taken using a terminal, a photo-taker can be included in the taken photo in a manner of being synthesized with the corresponding photo.

Claims

1. A mobile terminal comprising:

a display;

a memory configured to store at least one image fragment;

a first camera;

a user input unit configured to receive a shutter input; and

a controller configured to;

cause the display to display a preview screen of an image received from the first camera;

cause the display to display a prescribed one of the stored at least one image fragment on a prescribed region of the preview screen, wherein the prescribed one of the at least one image fragment comprises an image extracted from a region of a prescribed image, the extracted image corresponding to a first character to be shown in the prescribed region of the preview screen;

cause the display to indicate two regions for placing the first character on the preview screen;

perform right or left symmetrical conversion of the extracted image to be synthesized with the received image such that a symmetrically converted first character is shown in the prescribed region of the preview screen; and

cause the memory to store a synthesized image including the received image and a symmetrically converted version of the extracted image in response to the shutter input such that the symmetrically converted first character is shown when the stored synthesized image is displayed on the display,

wherein the two regions comprise;

a first region for placing the first character without performing the right or left symmetrical conversion; and

a second region for placing the first character by performing the right or left symmetrical conversion.

2. The mobile terminal of claim 1, further comprising a second camera, wherein the controller recognizes a face of a second character from an image received through the second camera and then synthesizes the recognized face of the second character with a face of the first character.

3. The mobile terminal of claim 1, wherein the controller detects an edge of a third character on the image received through the first camera and determines the prescribed region based on the detected edge of the third character.

4. The mobile terminal of claim 3, wherein the controller determines the prescribed region in a manner that the prescribed region avoids overlapping the detected edge of the third character.

5. The mobile terminal of claim 3, wherein the controller determines a height-directional length of the third character based on the detected edge of the third character and adjusts a size of the displayed one of the at least one image fragment based on the height-directional length of the third character.

6. The mobile terminal of claim 1, wherein the right or left symmetrical conversion is performed in response to selection of the second region, the second region selected while the two regions are indicated.

7. The mobile terminal of claim 1, wherein the first character placed in the first region and the first character placed in the second region are symmetrical.

8. A method of controlling a mobile terminal, the method comprising:

displaying a preview screen of an image received from a first camera on a display;

displaying a prescribed image fragment among at least one image fragment stored in a memory on a prescribed region of the preview screen displayed on the display, wherein the prescribed image fragment comprises an image extracted from a region of a prescribed image, the extracted image corresponding to a first character to be shown in the prescribed region of the preview screen;

causing the display to indicate two regions for placing the first character on the preview screen;

performing right or left symmetrical conversion of the extracted image to be synthesized with the received image such that a symmetrically converted first character is shown in the prescribed region of the preview screen; and

causing the memory to store a synthesized image including the received image and a symmetrically converted version of the extracted image in response to a shutter input received via a user input unit such that the symmetrically converted first character is shown when the stored synthesized image is displayed on the display,

wherein the two regions comprise;

a first region for placing the first character without performing the right or left symmetrical conversion; and

a second region for placing the first character by performing the right or left symmetrical conversion.

9. The method of claim 8, further comprising:

recognizing a face of a second character from an image received through a second camera; and

synthesizing the recognized face of the second character with a face of the first character.

10. The method of claim 8, further comprising:

detecting an edge of a third character on the image received through the first camera; and

determining the prescribed region based on the detected edge of the third character.

11. The method of claim 10, wherein the prescribed region is determined in a manner that the prescribed region avoids overlapping the detected edge of the third character.

12. The method of claim 10, further comprising:

determining a height-directional length of the third character based on the detected edge of the third character; and

adjusting a size of the displayed image fragment based on the height-directional length of the third character.
