Abstract: A method and an apparatus for recognizing a three-dimension object using a light source are provided. The method of recognizing a three-dimension object of a terminal including a display unit for displaying an operation state of the terminal and a shoot unit for receiving an image includes receiving a first image by setting a first brightness as a brightness of the display unit, receiving a second image by setting a second brightness as the brightness of the display unit, and recognizing the three-dimension object based on brightness change of a preset part by comparing the second image with the first image. The apparatus and the method for recognizing a three-dimension object prevent a security function from being incapacitated using a two-dimension photograph.
