摘要： A pointer positioning device for positioning an aiming point on a display screen of an image display comprises at least one auxiliary point, an image sensor and an optical filter. The auxiliary point is disposed at the peripheral of the display screen for generating a predetermined spectrum. The image sensor receives signals of the predetermined spectrum generated by the auxiliary point. The optical filter is disposed in front of the image sensor for filtering out spectrum outside the predetermined spectrum such that the image sensor can merely sense the signals of the predetermined spectrum, wherein the auxiliary point is utilized as a reference point for correcting an initial setup and positioning the aiming point so as to position the aiming point inside a predetermined range on the display screen. The present invention also provides a pointer positioning method adapted to the pointer positioning device.
