Abstract: A mobile terminal according to the present disclosure comprises: a terminal body; a display unit mounted on the terminal body; a first camera which is disposed on one surface of the terminal body and takes a photograph at a first angle of view; a second camera which is disposed adjacent to the first camera and takes a photograph at a second angle of view larger than the first angle of view; and a controller which sets a white balance reference value using image data acquired by the second camera and outputs, to the display unit, a corrected image acquired by correcting an image, captured by the first camera, on the basis of the white balance reference value.

Abstract: In one example embodiment, a lens calibration method includes generating a distorted image by distorting a pattern image that includes at least two reference points separated from a center of the pattern image by different distances. The method further includes generating lens calibration data by comparing the pattern image with the distorted image.
