A mobile terminal as disclosed and broadly embodied herein may include a 3D display configured to display an object that includes a first and second images and a controller configured to change a magnification of the object that includes a first scaled image and a second scaled image and to correct a binocular disparity between the first and second scaled images. The controller may be configured to determine a binocular disparity between the first and second scaled images, determine whether the binocular disparity is within a prescribed range of disparity, reposition at least one of the first or second magnified images based on the determined binocular disparity, and control the display to display the corrected first and second scaled images.
