MOBILE TERMINAL INCLUDING PROJECTOR AND CONTROL METHOD THEREOF
First Claim
1. A mobile terminal for providing a blackboard function, comprising:
- a projector 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 for processing the image transferred from the camera and transferring the processed image to a controller; and
the controller for detecting infrared rays from the photographed image so as to recognize an indication position of an indication device, which generates the infrared rays, in the projected image, and when the infrared rays are detected, displaying a preset mark on a position of the detected infrared rays by using the projector.

Abstract
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.

8. A method for providing a blackboard function to an image projected through a projector in a mobile terminal, the method comprising the steps of:
-
projecting an image through the projector of the mobile terminal; photographing the projected image by a camera of the mobile terminal; detecting infrared rays from the photographed image so as to recognize an indication position of an indication device generating infrared rays in the projected image; and when the infrared rays have been detected from the photographed image, displaying a preset mark at a position, in which the infrared rays are detected, through the projector. - View Dependent Claims (9, 10, 11, 12, 13)
