INTERACTIVE IMAGE SYSTEM, INTERACTIVE APPARATUS AND OPERATING METHOD THEREOF

An interactive image system includes a host having a first wireless module and an access device for accessing software, at least one reference point for generating light of a predetermined spectrum and an interactive apparatus including a second wireless module, an image module, a modulation module and a processing unit. The image module captures images of the reference point with a sampling frequency to form a first image and a second image, calculates and outputs a moving vector of the images of the reference point between the first and second images. The processing unit controls the second wireless module to transmit the moving vector to the first wireless module and controls the modulation module to real-timely modulate the sampling frequency of the image module according to a predetermined condition. The present invention further provides an interactive apparatus and operating method thereof.
