The invention discloses a kind of methods for preventing off screen curtain excessively and closely causing myopia, comprising: step 1, acquires and identifies facial video data, identify the identity information of user；Step 2, by facial recognition techniques, analysis show that the face of user accounts for the ratio of entire picture；Step 3, in the case where determining that the ratio is higher than the first preset value, display screen is closed；In the case where determining that the ratio is lower than the second preset value, the display screen is opened；First preset value is higher than the second preset value.The method for preventing off screen curtain excessively and closely causing myopia overcome in the prior art due to off screen curtain excessively closely without reminding the problem of, realize the excessively close breath screen of off screen curtain and remind.
Description
Technical field
Field the present invention relates to TV, mobile phone, tablet computer, computer etc. with screen electronic displays, and in particular, to anti-
Only off screen curtain closely leads to the method for myopia excessively.
Background technique
From pervious TV, computer, mobile phone, tablet computer till now, people use these electronic equipments with screen
Time it is increasingly longer, and wherein bring causes the influence of myopia also more and more, not strong particularly with ability of self control and regard
Neurodevelopment is again even more so for also incomplete children.It needs one kind that can identify using distance and carries out screen control
System prevented the close up from seeing screen.Existing technology is usually in the way of infrared ray or ultrasonic distance measurement currently on the market
To judge user, whether off screen curtain is too close, so that screen be automatically closed to remind user that suitable distance is kept to prevent to reach
The purpose of myopia.
The problem of this method be it is not smart enough, when there is other object to pass through out of supersonic finding range, be easy
It judges by accident screen to pass, but also specially to increase a range finder module, also increase cost.
Summary of the invention
The object of the present invention is to provide a kind of methods for preventing off screen curtain excessively and closely causing myopia, this prevents off screen curtain from closely leading excessively
Cause myopia method overcome in the prior art due to off screen curtain excessively closely without reminding the problem of, it is excessively close to realize off screen curtain
Breath screen is reminded.
To achieve the goals above, the present invention provides a kind of method for preventing off screen curtain excessively and closely causing myopia, this is prevented
Off screen curtain closely cause excessively myopia method include:
Step 1, it acquires and identifies facial video data, identify the identity information of user；
Step 2, by facial recognition techniques, analysis show that the face of user accounts for the ratio of entire picture；
Step 3, in the case where determining that the ratio is higher than the first preset value, display screen is closed；
In the case where determining that the ratio is lower than the second preset value, the display screen is opened；
First preset value is higher than the second preset value.
Preferably, before step 1, in the case where sensing user, acquisition device is opened, to acquire user's
Video data.
Preferably, in step 1, facial video data is acquired using camera.
Preferably, in step 3, in the case where determining that the ratio is higher than the first preset value, prolong the first preset time pass
Close display screen.
Preferably, first preset time is 2s-3s.
Preferably, in step 3, in the case where determining that the ratio is lower than the second preset value, prolong the second preset time and open
Open the display screen.
Preferably, second preset time is 2s-3s.
Preferably, first preset value is 60%；Second preset value is 50%.
According to the above technical scheme, camera facial recognition techniques of the present invention are also mature technology scheme, this patent scheme
In do not need to identify specifically used person's facial characteristics, it is only necessary to identify facial range, implement simpler；It is at low cost,
For mobile phone, tablet computer, laptop, front camera has been standard configuration, without any hardware cost of increase；For electricity
Depending on and desktop computer screen also only need increase a front camera, be the highly developed and cheap scheme of technology；This hair
Bright discrimination is high, and when needing to cut off screen, user must be that front faces screen and off screen curtain is close enough, is not easy to judge by accident.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
The drawings are intended to provide a further understanding of the invention, and constitutes part of specification, with following tool
Body embodiment is used to explain the present invention together, but is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the flow chart for illustrating a kind of method for preventing off screen curtain excessively and closely causing myopia of the invention.
Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention provides a kind of method for preventing off screen curtain excessively and closely causing myopia, this, which prevents off screen curtain excessively, closely leads to myopia
Method includes:
Step 1, it acquires and identifies facial video data, identify the identity information of user；
Step 2, by facial recognition techniques, analysis show that the face of user accounts for the ratio of entire picture；
Step 3, in the case where determining that the ratio is higher than the first preset value, display screen is closed；
In the case where determining that the ratio is lower than the second preset value, the display screen is opened；
First preset value is higher than the second preset value.
According to the above technical scheme, camera facial recognition techniques of the present invention are also mature technology scheme, this patent scheme
In do not need to identify specifically used person's facial characteristics, it is only necessary to identify facial range, implement simpler；It is at low cost,
For mobile phone, tablet computer, laptop, front camera has been standard configuration, without any hardware cost of increase；For electricity
Depending on and desktop computer screen also only need increase a front camera, be the highly developed and cheap scheme of technology；This hair
Bright discrimination is high, and when needing to cut off screen, user must be that front faces screen and off screen curtain is close enough, is not easy to judge by accident
In a kind of specific embodiment of the invention, before step 1, in the case where sensing user, open
Acquisition device, to acquire the video data of user.
In a kind of specific embodiment of the invention, in step 1, facial video data is acquired using camera.
In a kind of specific embodiment of the invention, in step 3, feelings of the ratio higher than the first preset value are being determined
Under condition, prolongs the first preset time and close display screen.
In this embodiment, first preset time is 2s-3s.
