In order to technical scheme is described, illustrate below by specific embodiment.
Preset Time is referred to from user and starts time of the eye closing between television shutdown in the present invention, using timing
Device is used as the timing tool of Preset Time, it is preferable that the intervalometer adopted in all embodiments of the present invention is respectively provided with following
Characteristic：Intervalometer can start simultaneously at timing in startup, and can carry out counting clearing when closed.Due to existing intervalometer species
More, such as some intervalometers can be carried out counting clearing in the state of having been started up and start the operation of timing, and need
The order for receiving startup timing can just restart timing, and it is this fixed that the intervalometer in embodiments of the invention can also be adopted
When device be used as the timing tool of Preset Time, now when detecting user and being not at closed-eye state, without the need for Off Timer,
Only need to the operation for carrying out counting clearing.
As different user is not quite similar to the demand of Preset Time, such as certain customers like eye closing to listen TV programme,
Duration demand of the certain customers to Preset Time, much larger than the default time duration for the default system of general user, if
All users can only carry out television shutdown management using the default time of system as Preset Time, it may appear that Consumer's Experience
Not good situation.
In invention, in order that user manages more personalized, lifting Consumer's Experience to television shutdown, user is using this
When the method that invention is provided carries out television shutdown management, except a default default mode and a default time are as shutdown mode and in advance
If beyond the time, also providing single pattern, Preset Time is set in order to User Defined, single pattern means this setting
Preset Time be only applicable to control this television shutdown, when next television shutdown again need reset.When user wishes
Hope when the Preset Time of this television shutdown management is only set, when can select using single pattern and be input into associated default
Between, such as user wants rest of dozing off when TV is seen today, needs longer Preset Time, and now user can arrange this shutdown
Pattern is single pattern, and is input into the Preset Time for wishing shutdown.
When user is not desired to the Preset Time that arranges shutdown every time, when wishing to one again and being more suitable for oneself default
Between when, the corresponding default time of default mode of setting system can be selected.TV Festival is listened as user likes closed eyes usually
Mesh, falls asleep after often listening the TV of half an hour, and now default time is set to half an hour by user, the default time meeting
Persistently using before carrying out default time setting next time to user, if user does not set after default time is arranged always again
Determine default time, then this time default time is set will the corresponding Preset Time of pattern by default always.
If user is not provided with single pattern, also default time is not configured, can then be adopted in the present invention default
Default mode and default default time as current shutdown mode and Preset Time, the default default time is needed by this
Art personnel are determined according to the experience of investigation and working to user.
Embodiment 1
Fig. 1 shows that the television shutdown control method based on eye recognition that the embodiment of the present invention 1 is provided realizes flow process,
Details are as follows：
In S101, collection eye image simultaneously obtains human eye state, judges whether human eye state is closed-eye state.
Before Preset Time and shutdown mode are obtained in S101, also include：
Judge whether user arranges single pattern, if user setup single pattern, single pattern is set to the mould that shuts down
Formula, and the Preset Time being associated with single pattern of receiving user's input.If user be not provided with single pattern and default when
Between, then default mode and default time are used as current shutdown mode and Preset Time, wherein, if user is to default time
Carried out setting, then using user setup after default time as Preset Time.
Also include before collection eye image in S101, carried using TV or external photographing module obtains user's
Facial image, and extract eye image from facial image to carry out subsequent treatment.
Human eye state is judged according to eye image in S101, including：
Collection eye image, and carries out two-dimension discrete cosine transform to the eye image for getting, obtain eye-observation to
Amount sequence；
Likelihood value calculating is carried out by built-in type hidden Markov model to eye-observation sequence vector, likelihood value is obtained；
Judge whether likelihood value reaches the threshold value in closed-eye state；If reaching, then it is assumed that human eye is in closed-eye state.
Two-dimension discrete cosine transform (2D-DCT) conversion is sampled and each sample window is carried out to eye image, by
Low frequency coefficient after 2D-DCT conversion constitutes eye-observation sequence vector, then using built-in type hidden Markov model, calculates
The likelihood value of the sequence is similarity degree, opens closed state according to what this likelihood value judged eyes, more than above-mentioned two-dimensional discrete
String conversion is prior art with built-in type hidden Markov model, and the present invention is not described in detail.
Judge whether human eye state is closed-eye state in S101, human eye state includes two kinds, i.e., be not eye closing (eye opening)
State and closed-eye state, wherein：
If not closed-eye state, then Off Timer, resets the counting of intervalometer, and returns execution collection eye image
And human eye state is obtained, judge that whether human eye state is the operation of closed-eye state.
When judge for eyes-open state when, then it is assumed that user does not enter into sleep state, and now TV need not be carried out
Shutdown carries out timing also without intervalometer, so when human eye state being judged for opening eyes, detect timer state, if timing
Device is in inactive state, then directly return in S101 and gather eye image and obtain human eye state, whether judge human eye state
For the operation of closed-eye state, and subsequent operation is re-started, if intervalometer is in the state that has been turned on, Off Timer, it is fixed to make
When device counting reset, return again to the collection eye image in S101 and obtain human eye state, judge whether human eye state is to close
The operation of eye state, and re-start subsequent operation.By the operation, user can be effectively ensured when normal viewing TV
It is not in the situation for controlling television shutdown by mistake.
In S102, if human eye state is closed-eye state, when judging whether the time in closed-eye state reaches default
Between.
Judge whether the time in closed-eye state reaches Preset Time, including：
Judge whether intervalometer starts；
If intervalometer is not actuated, control timer starts；
If intervalometer has been turned on, judge whether the counting of intervalometer reaches Preset Time；
If intervalometer reaches Preset Time, judge that the time in closed-eye state reaches Preset Time；If intervalometer is not
Preset Time is reached, then judges to have not timed out up to Preset Time in closed-eye state.
When human eye state is judged for closing one's eyes, the time for checking eye closing is needed whether to reach Preset Time, but in electricity
Regarding when just start shooting or judge human eye state as opening eyes, all can Off Timer, it is impossible to be timed device timing, so sentencing
Break and human eye state for during eye closing, in addition it is also necessary to check that timer state, whether in having been turned on, needs to start if not actuated and determines
When device, and start the timing of Preset Time.
Identifying that with human eye state be eye closing, and intervalometer is really sentenced in when having turned on, check whether intervalometer reaches
Preset Time, if intervalometer does not also reach Preset Time, needs the human eye state for continuing monitoring user, so needing to return
Execute to gather in S101 and eye image obtain human eye state, judge that whether human eye state is the operation of closed-eye state, until supervising
The time that survey user closes one's eyes reaches Preset Time and turns off TV.
If not up to Preset Time, returns and executes collection eye image and obtain human eye state, whether judge human eye state
Operation for closed-eye state.
In S103, if reaching Preset Time, current shutdown mode is obtained, and judges whether current shutdown mode is single
Pattern；If current shutdown mode is single pattern, controls current shutdown mode and switch to default mode, and control television shutdown.
User's eye closing is being detected, when intervalometer has been turned on and reaches Preset Time, is needing to shut down TV,
But when this shutdown mode is single pattern when user setup, in order that single pattern of this setting and associated
Preset Time does not affect the use of user's next time, does not affect next shutdown mode and Preset Time, needs the list for arranging this
Secondary pattern and associated Preset Time switch to default mode and default time, then carry out television shutdown, now carry out next time
When the management of television shutdown, even if user is not provided with shutdown mode and Preset Time, the shadow of this setting will not be also subject to
Ring.By current shutdown mode be single pattern switching into default mode while, can also delete pre- with what single pattern was associated
If the time.
