Description of drawings:
The structural representation of Fig. 1 for using among the present invention;
Fig. 2 is an operation principle block diagram of the present invention.
Embodiment:
The present invention includes video camera 1, people's face detection module device 5, human eye feature analysis modular device 2, background server 3 and mode of operation switch controller 4; The output of video camera 1 connects people's face detection module device 5; The output of people's face detection module device 5 connects human eye feature analysis modular device 2 and background server 3 respectively; The output of human eye feature analysis modular device 2 connects background server 3, and the output of background server 3 connects mode of operation switch controller 4.
A kind of television operating mode changing method based on human eye feature analysis is through human eye feature analysis, confirms that beholder's human eye is opened entire, direction of visual lines, further confirms the method that television operating mode switches.
Concrete job step is following:
(1) television set the time, video camera is opened and is also carried out video acquisition;
Whether (2) people's face detection module device 5, and the image information of obtaining from video camera 1 is analyzed, have people's face to occur to judge:
If unmanned face information sends to background server 3 with analytical information;
If people's face information is arranged, detected people's face information is sent to human eye feature analysis modular device 2;
(3) human eye feature analysis modular device 2 uses human eyes location and human eye line-of-sight detection algorithm based on sight angle; Human eye information from video camera 1 is analyzed; Confirm that beholder's eyes open entire and direction of visual lines, and analysis result is sent to background server 3;
