Abstract: A method of controlling a mobile terminal includes the steps of injecting a laser signal to a direction at which a camera is facing, receiving a reflected laser signal corresponding to the injected laser signal returned in a manner of being reflected to a subject, calculating a distance from the subject using a difference between time of injecting the laser signal and time of receiving the reflected laser signal, calculating standard illuminance of a flash based on the distance from the subject, injecting light by controlling the flash according to the standard illuminance and storing a first image including the subject using a camera module. According to the method, since it is able to obtain an image of which a whole screen is maintained by a reasonable brightness, a subject and a background can be included in an image.
