An apparatus and a method for implementing augmented reality by using a transparent display are provided. The method includes calculating a point-of-view of a user based on a face image captured by a front camera, detecting an image of an area depending on an angle of view identical to a viewing angle of the user based on the calculated point-of-view of the user, implementing the augmented reality by using the detected image, and outputting the implemented augmented reality to the transparent display.
