Abstract
An apparatus and a method for recognizing a pointing position in a video display system with a remote controller are disclosed. A plurality of optical sensors provided in a video display system are utilized to compute a position (on a picture) indicated by output signals of a remote controller, thereby executing a particular menu by the remote controller. The apparatus includes an optical receiving section for outputting different electric current values in accordance with the intensities of incoming optical beams incoming from a remote controller. Further, a switching section receives the different electric current values to output a selected electric current value in accordance with a selecting signal. An A/D converting section receives the selected electric current value from the switching section to convert it into a digital signal. A control section outputs a selecting signal to the switching section if no interrupt signal is received from a relevant sensor of the optical sensing section, for computing a position value based on an indication by the remote controller (of a user) in accordance with digital signals incoming from the A/D converting section, for outputting an interrupt signal for notifying the position data and a data input in accordance with a computed value, and for outputting a selection signal to the switching section. A menu executing section executes a user'"'"'s selected menu in accordance with the interrupt signal and the position data of the control section. The functions can be easily manipulated by the user, and if there is many elements in the picture, the selection of the elements can be speedily and accurately carried out.
