Mobile terminal and control method therefor

A mobile terminal, comprising:

• a terminal body;
• a touch screen;
• a camera provided in the terminal body and including first and second lenses having different telephoto ratios;
• and
• a control unit to:
• extract a first image captured through the first lens and a second image captured through the second lens, which satisfy a common capturing condition, from a plurality of images captured through the first and second lenses, respectively, and
• correlate the first image and the second image with each other, with respect to a specific subject,
• wherein the control unit,
• correlates a first region of the first image including a first graphic object corresponding to the specific object with a second image including a second graphic object corresponding to the specific object, and
• controls the touch screen to output the second image when a preset touch is applied to the first region of the first image in a state where the first image is output on the touch screen,
• wherein the control unit is further configured to:
• when the second image is captured through the second lens corresponding to a telephoto lens after the first image is captured, extract the first and second graphic objects corresponding to the specific object from each of the first image and the second image, by using feature points of graphic objects included in the first image and the second image, and specify, as the first region, a region of the first image which corresponds to the second graphic object included in the second image and includes the first graphic object.
