Interactive image system, interactive apparatus and operating method thereof

An interactive apparatus adapted to an interactive image system which comprises the interactive apparatus, a host wirelessly coupled to the interactive apparatus and at least one reference point configured to generate light of a predetermined spectrum, the interactive apparatus comprising:

• a wireless module for data communication with the host;
• an image module having a sensing array for capturing images of the reference point with a sampling frequency to form a first image and a second image, calculating and outputting a position variation of the images of the reference point in the first and second images;
• a modulation module for setting the sampling frequency of the image module;
• and
• a processing unit for controlling the wireless module to transmit the position variation to the host, and controlling the modulation module to set the sampling frequency of the image module according to movement per unit period of time of the images of the reference point with respect to the sensing array.

An operating method of an interactive apparatus which is adapted to an interactive system comprising the interactive apparatus, a host wirelessly coupled to the interactive apparatus and at least one reference point configured to generate light of a predetermined spectrum, the operating method comprising the steps of:

• capturing, by an image module having a sensing array, images of the reference point with a sampling frequency to form a first image and a second image;
• calculating and outputting a position variation of the images of the reference point in the first and the second images;
• and
• setting, by a processing unit, the sampling frequency of the image module according to movement per unit period of time of the images of the reference point with respect to the sensing array.
