Abstract
The invention relates to a television automatic waiting device, which comprises image collecting module, image processing module and executing module. Wherein, the image collecting module collects the external image at the front of television; the image processing module receives and stores the collected images and compares the images to send instruction; the executing module receives said executing instruction to process automatic wait function. The invention can adjust the time space of image comparison to optimize the waiting condition for different families to save energy and prolong the service life of television.
Description
One, technical field
The present invention relates to a kind of automatic stand-by device for television.
Two, background technology
Television set especially plasma TV power consumption in use is very large, and the power of general 42 cun plasma TV is 300 watts, and 50 cun power is 450W.Can occur in the situation of forgetting the closing television machine of leaving when seeing TV in daily life unavoidably, perhaps sleeping and can't the closing television machine when seeing TV, so just caused the huge waste of electric energy.Though existing television set also can be realized the automatic stand-by function, the realization of this function is by preestablishing the time, just enter holding state after the time arriving.Whether this function can't see that TV judges whether that needs enter holding state according to the people, just judging according to the time of machinery enters holding state, the shortcoming of existing this automatic stand-by function is: do not possess hommization, simultaneously because picture tube or plasma LCDs are under the "on" position for a long time, wear out easily, shortened the useful life of television set; And can't realize the function of power saving easily causing waste of power resources.
Three, summary of the invention
The purpose of this invention is to provide a kind of automatic stand-by device for television, this device can make television set enter holding state automatically under the unmanned situation about using of open state, thereby has saved electric energy.And, because the display device of all television sets has a hour age limit, thus under unmanned situation about using automatic stand-by, can make picture tube or plasma and LCDs be not easy to wear out, increased the useful life of television set.
The objective of the invention is to be achieved through the following technical solutions:
A kind of automatic stand-by device for television is characterized in that: it comprises image collecting module, image processing module and Executive Module; Described image collecting module is used for gathering the extraneous image of television set front; The image that image processing module is used for receiving, the stored images acquisition module collects, and image that collects and the image that last time collected carried out sending instruction after the image contrast; After Executive Module receives the execution command of image processing module, television set is realized automatic stand-by control.
Among the present invention, the every certain interval of time of described image collecting module is gathered the extraneous image of television set front; Described every certain interval of time is to set according to the concrete condition that each family uses.The image comparison interval time that sets is set in order to realize the optimization waiting condition that is fit to each family's use.
Described image processing module comprises shadow memory, image comparator and microprocessor; The image that sends after the image collecting module collection is stored in the image holder by microprocessor earlier, in the time interval of setting, by microprocessor the image in the shadow memory is sent in the image comparator and to compare.
The present invention is provided with controller in Executive Module, controller is realized automatic stand-by control by the execution command of the image processing module that receives to television set.
Signal of video signal described in the present invention is with the form output of digital signal.
The function of Executive Module is the instruction that receives image processing module among the present invention, makes television set enter holding state.
The present invention can make television set enter holding state automatically under the unmanned situation about using of open state, thereby has saved electric energy.And, can make picture tube or plasma and LCDs be not easy to wear out, increased the useful life of television set.
Four, description of drawings
Fig. 1 is the structural representation of automatic stand-by device for television of the present invention;
Fig. 2 is an explanation workflow diagram of the present invention.
Five, embodiment
Below, come automatic stand-by device for television of the present invention is elaborated with reference to accompanying drawing.
Fig. 1 is the structural representation of automatic stand-by device for television;
Automatic stand-by device for television has following a few part:
Image collecting module 1: make a video recording to carrying out timing in the visual range of television set by the shooting equipment, and the image that collects is input to image processing module 2.Shooting is set in order to realize the optimization waiting condition that is fit to each family's use blanking time.
Image processing module 2: microprocessor 23 carries out timing ratio with the image that collects, if the image of two states relatively is not exclusively the same, illustrates that then the people is seeing TV.If the image that draws is static, then explanation nobody is seeing TV or is entering sleep state.
Executive Module 3: receive the control signal of image processing module 2, regulate television set and enter holding state.
The camera head of installing on the television set is gathered the extraneous image of television set front as seen from Figure 1, camera head arrives microprocessor with the signal conveys that collects, whether microprocessor is using television set by regularly image being compared to handle to judge whether the picture of image changes thereby judge the people.The result of microprocessor processes is transported to the controller 31 in the Executive Module 3, thereby realizes the function of standby by the standby command that controller sends.
Can regulate image judgement time relatively according to the personal considerations, thereby according to the actual best service condition that is fit to each family that draws.The present invention does not influence existing timing automatic idle function in addition.When not needing to use automatic stand-by device for television of the present invention, also can directly close this function.
Fig. 2 is an automatic stand-by device for television workflow schematic diagram.
As shown in Figure 2 after the automatic stand-by functional device is opened, the image modalities that is installed on the television set is just started working, gather image at set intervals and send to image processing arrangement and compare, if the image in blanking time does not change, illustrate that then the people not seeing TV, just changes television set over to holding state.If image changes, then the people is seeing TV, just continues to gather image.The explanation of giving an example: the people is seeing TV when the image that collects for the first time, and at this moment the people walks to reach the kitchen, and television set carries out image collection second time, and it is vicissitudinous contrasting two images, and this judges that still the people is seeing TV, so proceed image collection.When gathering for the third time, the people is still in the kitchen, and the image that collects is with for the second time the same, so television set has just entered holding state.Studies show that the people can not keep a state constant, so the image that the people collected when seeing TV before television set is always vicissitudinous, can not enter holding state when seeing TV.
