Specific embodiment
Explanation is further explained to the present invention with specific embodiment below in conjunction with the accompanying drawings.
The present invention relates to a kind of method that action by people and sound change to control energy saving television, it includes following step
Suddenly：Step S0：A television set is provided, the television set includes Camera sensor, master controller；In advance in the master of television set
The image rate of change and the sound rate of change are set on controller；Step S1：Main controller controls front camera and Camera sensor
Start, film and audio are intercepted by Camera sensor；Main controller is analyzed to the film and audio that are truncated to；Step
S2：If image changes size<20% and sound change size<20% enters step S3, otherwise return to step S1；Step S3：Electricity
Enter dormancy in 30 minutes reciprocal depending on machine, and user is reminded in the form of audio；Judge the image rate of change is with the sound rate of change
It is no more than setting value, if then return to step S1, otherwise TV set controller control television set enter resting state.Idiographic flow
Schematic diagram is referring to Fig. 1.
, by Camera sensor come regularly capturing picture and sound, each Frame is determined whether greatly for we
Amount picture change, all judge whether sound has substantial amounts of variation within every 0.1 second, if long-time all do not detect picture and
The variation of sound, such as, by being all less than within 30 minutes 10% variation, advance to countdown, and preparation allows TV to enter
The state of dormancy, and " eyes " small icon is shown on television image, to point out user, being left 30 minutes TVs will enter
Resting state, last five minutes, again with auditory tone cues user, TV will enter resting state to TV, be used to strengthen prompting to make
User.If user is during this period, it is possible to use the action waved, or the behavior of sound is sent, allow Camera Sensor
Substantial amounts of picture change or significantly sound vibrations change are sensed, has just cancelled the pattern for entering automatic stand-by.
First, image identification
User can meet the need of user by the desired image of menu picture sets itself and sound rate of change size
Ask, or the time point that television image prompting, auditory tone cues occur can also be by menu picture sets itself.
Film is saved as RAW Data images, first by photo black and white by the present invention after Camera sensor capture film
After change, then with previous photo-overlap, by the image overlap method of Invert, the diversity factor of overlapping photographs is calculated, can be very
Readily judge, the varying degrees size of overall image.By taking the portrait film interception photo in Fig. 2 as an example, palm will be stretched out
Picture Fig. 2 b are Chong Die with picture Fig. 2 a that previous does not extend out palm to obtain Fig. 2 c, the picture from overlap that we can will be apparent that
In see that the palm of people is main otherness, it is main although the front and rear image of people has narrow difference by the identification of image
The difference wanted in palm, can before and after invert merges after image, if calculate diversity factor obtain difference value thus people
Through leaving or having fallen asleep, substantial amounts of change value would not be produced.
2nd, voice recognition
It is our system environments that we define TV first, and remote signal is the sound that the noise of surrounding and people send, near-end
Signal is the sound that TV sends in itself.
The sound that definition TV programme send in itself is A, and noise is B, and the sound that people sends is C.
Source 1 first enrolls near end signal, and Source 2 can enroll near end signal and add by Camera sensor
The merging signal of remote signal, Source 3 assumes that we can also enroll sound when people is when sound is sent.
Table 1
| TV | Noise | Human | |
| Source 1 | A | ||
| Source 2 | A | B | |
| Source 3 | A | B | C |
Referring to table 1, Source 2 is subtracted into Source 1 can obtain B, that is, Noise sample, and sound is gone out in human hair
When, we can obtain Source 3, and the same time,, by internal sound signal, we can also obtain Source 1 for we,
Source 3 is subtracted into Source 1, then subtracts the Noise sample for previously obtaining（Noise sample）, we can be obtained by
Human hair goes out the variation of sound.
In specific embodiment, human hair goes out sound plus broadcast sounds Fig. 3, and broadcast sounds Fig. 4.
Flow more than, we can obtain the variation difference value of system environments sound.
When user expects that image is less than 20% with the sound rate of change, by after 30 minutes, television set can just shut down, and
There is picture to point out in the when of falling dozens of minutes, it is reciprocal five minutes when, have voice message.
