1. A mobile terminal comprising: a controller; a holography storing medium configured to record an interference pattern generated by interference of light; and a holography output module configured to output a holography image attributed to diffraction between the light applied to the holography storing medium and the interference pattern in accordance with at least one preset holography type among a plurality of holography types under the control of the controller, wherein a plurality of the holography types comprise a default type, a holography background type and a holography pattern type, wherein if the default type is set, the controller controls the generated holography image to be outputted intactly, wherein if the holography background type is set, the controller controls the holography image to be outputted in a manner of being included in a 1st region within a preset holography background, and wherein if the holography pattern type is set, the controller controls the holography image to be outputted in accordance with the preset at least one holography pattern.
