摘要：
A cursor control method for controlling a cursor on an image display includes: providing at least two reference points for generating light of a predetermined spectrum and defining a predetermined area; providing an image sensor pointing inside the predetermined area; receiving the light of the predetermined spectrum by the image sensor to form a digital image; identifying positions and shapes of the images of the reference points on the digital image to form a first parameter; performing distance and angle compensations on the first parameter; moving the aiming point of the image sensor inside the predetermined area to form a second parameter; and calculating an displacement of the images of the reference points on the digital image according to the compensated first and second parameters so as to accordingly control the cursor. The present invention further provides a cursor control apparatus.
