1. A remote control comprising:
- a plurality of sensors which sense movement of the remote control; and
a control unit which turns on at least one sensor of the plurality of sensors and thereby senses movement of the remote control, and determines whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control.

Abstract
A remote control is provided including a plurality of sensors which sense movement of the remote control, and a control unit which turns on at least one sensor of the plurality of sensors and thereby senses movement of the remote control, and determines whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control. Consequently, battery consumption is reduced.

11. An image display system comprising an image display apparatus and a remote control,
wherein the remote control comprises: -
a plurality of sensors which sense movement of the remote control; a control unit which turns on at least one sensor of the plurality of sensors and thereby senses movement of the remote control, and determines whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control; an analog to digital converter (ADC) which converts analog signals output from the sensors into digital signals; and a transmission unit which converts the converted digital signals into transmittable signals and transmits the transmittable signals, and wherein the image display apparatus comprises; a display; a reception unit which receives the signals from the remote control; and a control unit which converts the received signals into displayable signals and displays the converted signals on the display.

12. A method of controlling an image display system including an image display apparatus and a remote control, which includes a plurality of sensors, the method comprising:
-
turning on at least one sensor of the plurality of sensors and thereby sensing movement of the remote control; determining whether to turn on or off the remaining sensors according to whether or not the at least one sensor senses movement of the remote control; converting analog signals output from the plurality of sensors into digital signals if the plurality of sensors are turned on; converting the converted digital signals into transmittable signals and transmitting the transmittable signals to the image display apparatus; and receiving the transmitted signals, converting the received signals into displayable signals and displaying the converted signals.
