<P>PROBLEM TO BE SOLVED: To provide: an interactive picture system which reduces electric power consumption by modulating the sampling frequency of the picture module of an interactive apparatus; the interactive apparatus; and its operation control method. <P>SOLUTION: The interactive picture system includes a host 10 having the first radio module 16 and an access device 18 to soft ware; one or more reference points which form the light of a predetermined zone; and the interactive apparatus 20. The interactive apparatus 20 has the second radio module 25, the picture module 21, a modulation module 23, and a processing part 22. The picture module 21 images the reference point at predetermined sampling frequency to form the first picture and the second picture and calculates and outputs the movement vector of the image of the reference point between both the pictures. The processing part 22 controls the second radio module 25 to transmit the movement vector to the first radio module 16 and controls the modulation module 23 according to a predetermined condition to immediately modulate the sampling frequency of the picture module 21. This invention further provides the interactive apparatus and its operation control method. <P>COPYRIGHT: (C)2009,JPO&INPIT |
