Mobile terminal and control method therefor
The present invention relates to a mobile terminal having an image capturing function and a control method therefor. The mobile terminal according to one embodiment of the present invention comprises: a camera; a display unit for outputting images received through the camera; and a control unit for outputting the images to a part of an output area of the display unit and controlling the display unit such that the images are outputted in a preset manner, wherein the control unit outputs the image in a region other than a region in which the image is outputted during the capturing on the basis of capturing of the images, such that different images related to an iris are captured.
1. A mobile terminal, comprising:
a camera;
a display unit configured to output an image received through the camera; and
a controller configured to:
output the image in a first area of a display area of the display unit and control the display unit to output the image in a preset manner;
output the image in a second area of the display area different from the first area in response to capturing of the image displayed in the first area such that different iris-related images are captured;
capture the image output in the first area as a first image;
in response to the capturing of the image displayed in the first area, change an output position of the image from the first area to the second area without moving the mobile terminal so as to induce a change of a user's gaze; and
capture the image output in the second area as a second image,
wherein the first image and the second image are the different iris-related images.
2. The terminal of claim 1 , wherein an output size of the image is constantly maintained even if the output area of the image is changed.
3. The terminal of claim 1 , wherein the capturing is performed in response to an iris-related image being recognized in the image.
4. The terminal of claim 3 , wherein the controller performs the capturing, in response to the output of the iris-related image being maintained for a preset time while the iris-related image is output in the image.
5. The terminal of claim 3 , wherein the controller outputs the image in another area, other than capturing the image, when the iris-related image recognized in the image satisfies a preset condition.
6. The terminal of claim 5 , wherein the preset condition is a case where brightness of at least part of the iris-related image is higher than reference brightness.
7. The terminal of claim 1 , wherein the controller outputs the image in a second output size different from a first output size when the image is captured while the image is output in the first output size.
8. The terminal of claim 1 , wherein:
the capturing of the image is performed a preset number of times; and
the controller is further configured to change the output position of the image from one area of the display area to another area of the display area every time when the image is captured.
9. A method for controlling a mobile terminal, the method comprising:
outputting an image received through a camera in a first area of a display area of a display unit;
controlling the display unit to output the image in a preset manner;
outputting the image in a second area of the display area different from the first area in response to capturing of the image displayed in the first area such that different iris-related images are captured;
capturing the image output in the first area as a first image;
in response to the capturing the image displayed in the first area, changing an output position of the image from the first area to the second area without moving the mobile terminal so as to induce a change of a user's gaze; and
capturing the image output in the second area as a second image,
wherein the first image and the second image are the different iris-related images.
10. The method of claim 9 , wherein:
the capturing of the image is performed a preset number of times; and
the output position of the image is changed from one area of the display area to another area of the display area every time when the image is captured.
