摘要：
A remote pointing apparatus is provided. A light receiving unit may receive emitted light. A filtering unit may filter a received signal to a first frequency component, a second frequency component, a third frequency component, and a fourth frequency component. A calculation unit may compare amplitudes of the first frequency component and the second frequency component to calculate a first coordinate axis value of a cursor on a display unit, and compare amplitudes of the third frequency component and the fourth frequency component to calculate a second coordinate axis value of the cursor on the display unit.
