20090051651	APPARATUS FOR REMOTE POINTING USING IMAGE SENSOR AND METHOD OF THE SAME - Problem: since a remote pointing system using an image sensor and having a communication function through an infrared remote controller is used in various environments, the various environments have to be considered when designing the system. Solution: a signal reception unit outputs a control signal controlled to operate in a mode that corresponds to an infrared signal received from a remote controller among a remote control mode and a remote pointing mode. When receiving a control signal controlled to operate in the remote pointing mode from the signal reception unit, an image reception unit is operated to obtain a background image during a first signal reception section and obtains an optical image that corresponds to an infrared signal received from the remote controller during a second signal reception section. The infrared signal is not received during the first signal reception section and received during the second signal reception section from the remote controller. An image-processing unit creates a corrected optical image according to a difference value between the optical image and the background image. A pointing calculator calculates a distance up to the remote controller according to the size of the corrected optical image inputted from the image-processing unit and calculates a movement amount of the remote controller according to the calculated distance, thereby solving the above problem.	02-26-2009
