Publication number: 20090051651Abstract: 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.Type: ApplicationFiled: January 5, 2006Publication date: February 26, 2009Inventors: Sang-Hyun Han, Jae-Han Lee, Chang-Suc Han, Woo-Seok Song
