Disclosed is a mobile terminal for providing a blackboard function to an image projected through a projector, which includes a projector for projecting an image on a screen, a camera for photographing the image projected through the projector and transferring the photographed image to an image processor. The image processor processes the image transferred from the camera and transfers the processed image to a controller. The controller controls the operation of the mobile terminal including recognizing an effective region for the projected image where infrared rays are detected from the photographed image so as to recognize an indication position of an indication device. The indication device generates infrared rays, in the projected image, and when the infrared rays are detected, a preset mark is displayed on a position of the detected infrared rays by using the projector.
