Mobile terminal and controlling method thereof

摘要

A mobile terminal and controlling method thereof are disclosed, by which fluctuation of a screen can be reduced. The present invention includes a lens, a lens drive unit configured to move the lens along an x-axis and y-axis which are vertical to an optical axis and a z-axis parallel to the optical axis or to rotate the lens centering on the x-axis and the y-axis, an image pickup unit configured to generate a digital signal by detecting a light having passed through the lens, an image processor configured to create a preview image by applying an image processing to the digital signal, a display unit configured to display the preview image, and a controller, if a distance between the lens and the image pickup unit is shorter than a preset distance, controlling a partial region of the preview image to be outputted through the display unit.

1. A mobile terminal comprising:
a lens; a lens drive unit configured to move the lens along an x-axis and y-axis which are vertical to an optical axis and a z-axis which is parallel to the optical axis or to rotate the lens centering on the x-axis and the y-axis; an image pickup unit configured to generate a digital signal by detecting a light having passed through the lens; an image processor configured to create a preview image by applying an image processing to the digital signal; a display unit configured to display the preview image; a memory configured to store a lookup table having a display rate mapped to a distance between the lens and the image pickup unit; and a controller, if the distance between the lens and the image pickup unit is shorter than a preset distance, controlling a partial region of the preview image to be outputted through the display unit, wherein if the lens is moved along at least one of the x-axis and the y-axis or rotated centering on at least one of the x-axis and the y-axis, the controller controls a position of the partial region in the preview image to be changed by a displacement of the optical axis attributed to the movement of the lens, and wherein the controller determines the partial region in the preview image based on the display rate mapped to the distance between the lens and the image pickup unit.
