Embodiment
To combine accompanying drawing that the present invention is done further explain below.
See also Fig. 1, the display device 100 that the embodiment of the invention provides comprises display 10, one human face recognition systems, 20, one range finders 30 and a controller 40.This display device 100 can be used as electronic installation, for example the display device of TV, computing machine etc.
This display 10 comprises a display screen 11 and centers on the frame 12 of this display screen 11.This display screen 11 can be LCD, LED or traditional C RT display screen.These frame 12 inner hollow can be accommodated the various parts such as driving, control of this display screen 11.
This human face recognition system 20 and this range finder 30 are arranged at this frame 12 and expose this frame 12, face the dead ahead of this display screen 11.This controller 40 is arranged at this frame 12 inside.
This human face recognition system 20 comprises an image acquisition module 21 and an image processing module 22 that is electrical connected.This image acquisition module 21 exposes this frame 12, and this image processing module 22 is arranged at this frame 12 inside.This image acquisition module 21 is used to capture the object image in this display screen 11 the place aheads one scope.But this scope is the object scope of an identification image, and the ultimate range of the interior object of this object scope and this display screen 11 is greater than a safe viewing distance of this display screen 11.This safe viewing distance means can protect people's eyesight, prevent a near-sighted minimum viewing distance.This object scope can be owing to also have range finder 30 to do the detection and the judgement of concrete distance greater than this safe viewing distance.In general, this object scope is a bit larger tham this safe viewing distance and is got final product.
This image processing module 22 comprises a people's face presupposed information storer and an image comparison processor.This people's face presupposed information comprises people's the face of part at least information, for example eyes, nose etc.Whether this image comparison processor is compared the people's face presupposed information in this image acquisition module picked image and this people's face presupposed information storer has people's face to occur with identification.
This range finder 30 is provided with an infrared transmitter and a counter, and this counter shines this people's face according to infrared light and the distance of this people's face of Time Calculation of reflecting.This range finder 30 is used for when this image processing module recognizes these display screen 11 people from the place aheads face is arranged, and whether the distance of surveying this people's face and this display screen 11 is greater than this safe viewing distance.
This controller 40 electrically connects with this human face recognition system 20, range finder 30 and display 10.Under the switch 13 unlatching situations of this display 10, this controller 40 can be worked.This controller 40 keeps lighting opening at this display screen of control 11 under following two kinds of situation: know when having no talent face debating when this image processing module 22 (1); Explain that people's face does not appear in the object scope of this image acquisition module 21, promptly can be less than this safe viewing distance; (2) know these display screen 11 people from the place aheads face is arranged debating, and detect people's face apart from the time when this range finder 30 greater than a safe viewing distance when this image processing module 22.
Otherwise when detecting people's face distance less than a safe viewing distance when this range finder 30, these controller 40 these display screens 11 of control are closed.This is closed can only be display screen 11 blank screens and do not close the switch of display 10.In a further embodiment, this is closed also can be that the switch of display 10 cuts out, and promptly forces people outside the safety viewing distance, and this display 10 just can be held open state.
See also Fig. 2, the display control method of above-mentioned display device 100 can carry out according to following steps.At first, the switch 13 of the display 10 of this display device 100 is unlocked, and promptly the power supply of display 10 is switched on.
Secondly, human face recognition system 20 is unlocked in display screen 11 the place aheads one scope of detecting this display 10 of identification whether people's face is arranged.
Then, when this human face recognition system 20 had recognized people's face, whether range finder 30 was unlocked with the distance of surveying this people's face and this display screen 11 greater than a safe viewing distance.
Especially, in a further embodiment, above-mentioned human face recognition system 20 and range finder 30 can use same switch with display 10, when display 10 is unlocked, to open automatically, when the switch of display 10 is closed, close automatically.And the program of range finder 30 can be made as and receives that human face recognition system 20 just carries out range sensing when recognizing the signal of people's face.
At last; Know nobody during face through controller 40 debating when this human face recognition system 20; Control this display screen 11 and keep lighting opening; Know these display screen 11 people from the place aheads face is arranged debating, and when this range finder 30 detects people's face distance greater than a safe viewing distance, control these display screen 11 maintenances and light opening when this human face recognition system 20.Otherwise, when detecting people's face distance when this range finder 30, control this display screen 11 and close less than a safe viewing distance.This is closed can only be display screen 11 blank screens and do not close the switch of display 10.
In a further embodiment, this is closed also can be that the switch of display 10 cuts out, and promptly forces people outside the safety viewing distance, and this display 10 just can be held open state.
With respect to prior art; Whether display device provided by the invention comes the control display screen curtain to keep lighting and closing greater than a safe viewing distance through controller according to the people's face distance that detects; And in a scope, do not recognize people's face also the control display screen curtain keep lighting, force people to keep suitable viewing distance like this.
In addition, those skilled in the art can also do other variation in spirit of the present invention.Certainly, these all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
