A control apparatus for controlling an image display includes at least one reference object for generating a predetermined spectrum signal; a modulation unit for modulating the predetermined spectrum signal with a predetermined method; and a remote controller. The remote controller includes an image sensor for receiving the modulated predetermined spectrum signal and generating a digital signal; and a processing unit for receiving the digital signal, demodulating the digital signal so as to generate a digital image which only contains the image of the reference object, and calculating an image variation of the image of the reference object formed on the digital image, wherein the remote controller controls the image display according to the image variation thereby eliminating the interference from a light source which generates a light band overlapping the band of the predetermined spectrum signal. The present invention also provides a control method for controlling an image display.
