Under formula, the backlight brightness values of screen are lower, to reduce injury of the screen intensity of terminal to eyes of user under low-light level environment.
After terminal enters noctilucence screen mode, the brightness value of screen is a predetermined luminance value, which is 1nit~2.5nit
Arbitrary value in range, for example, 1.5nit, also, the numerical value of the predetermined luminance value can by user without departing from 1nit~
In the case where 2.5nit range, it is adjusted according to personal habits.
Exemplary, which is 4000k (Kelvin)~6500k, to incite somebody to action under noctilucence screen mode
The screen color temp of terminal is adjusted to warm colour.Likewise, the color temperature value of screen is a default color after terminal enters noctilucence screen mode
Temperature value, which is the arbitrary value within the scope of 4000k~6500k, for example, 5000k；Also, the preset color temperature value
Numerical value can be adjusted by user without departing from 4000k~6500k range according to personal habits.
Here, terminal can be by the human face expression in the facial image of identification acquisition, to determine belonging to human face expression
Classification, when human face expression classification is the first pre-set categories, controlling terminal enters noctilucence screen mode.First pre-set categories can be with
For, smile, frown and narrow any expression such as eye, for example, if the first pre-set categories be smile expression when, when user is bright in ambient enviroment
In the case that degree is very low, when needing to open noctilucence screen mode, user need to only make the expression of smile to terminal, and terminal can known
When the expression for being clipped to user is smile expression, into noctilucence screen mode, the intelligent control to the noctilucence screen mode of terminal is realized,
Easy to operate, practicability is high.
In the present embodiment, by specific environment brightness, and in the case where human face expression classification belongs to particular category, control
Terminal processed enters noctilucence screen mode, can make the unlatching of the noctilucence screen mode of terminal more intelligence with it is convenient, user does not need again
The noctilucence screen function that terminal is opened by being manually operated simplifies the operation of user, also, is realized by particular emotion to end

Indescribably take characteristic information.It is exemplary, the characteristic points such as eyes, eyebrow, nose, mouth, chin in every facial image are carried out
It positions and marks, facial image is done into normalized according to eye position, then eye is extracted using gal cypress (gabor) wavelet transformation
Textural characteristics around the characteristic points such as portion, eyebrow and eyes finally do dimensionality reduction normalized to the textural characteristics of extraction,
Obtain the characteristic information of every facial image.
In step A2, human face expression classification is determined according to the characteristic information based on facial expression classification model.
Here, which is by the trained disaggregated model for facial expression classification, example
, which may include: the sample set of (1) acquisition multiple groups difference expression classification, for example, frown narrow eye, face of wakeing up etc.
Various expressions；(2) according to above-mentioned preset feature extraction algorithm, the sample for extracting each sample in each sample set respectively is special
Sign, and the sample characteristics of extraction are inputted into classification (the sparse representation-based based on rarefaction representation
Classifier, SRC) in algorithm, classified by each sample characteristics of the SRC algorithm to input, obtain classification results；
(3) accuracy for judging classification results is adjusted the parameter of SRC algorithm in classification results inaccuracy, continues later pair
The sample characteristics of input are classified, and are adjusted according to parameter of the classification results to SRC algorithm, until it is high to obtain accuracy
The SRC disaggregated model of (for example, accuracy rate is more than 97%).
Here, when the characteristic information for the facial image that will be extracted inputs trained facial expression classification model, training
Good facial expression classification model can accurately identify human face expression classification according to the characteristic information of input.
What needs to be explained here is that due to judging the current face of user according to the human face expression classification in individual facial image
When portion's expression, it is likely that user occur and be accidentally made that the expression of the first pre-set categories or the terminal face table current to user
The situation of feelings judgement inaccuracy, is easy to produce maloperation.In order to avoid this maloperation, terminal available continuous at least two
It opens facial image and extracts the feature of every facial image at least two facial images using preset feature extraction algorithm
Information；The face in every facial image is determined according to the characteristic information of every facial image based on facial expression classification model
Expression classification；When human face expression in this at least two facial images belongs to same category A, determine that human face expression classification is
Category A.
Exemplary, terminal can use preset feature extraction algorithm, and continuous three collected to image acquisition component
The characteristic information of every facial image extracts in facial image, by facial expression classification model to every facial image
Characteristic information is identified, to identify the generic of the human face expression in every facial image.If continuous three face figures
The classification results of human face expression as in are that same category is such as frowned and narrowed at the moment, then can determine that the expression of active user is to frown
Ocular feelings are narrowed, in this way, ensure that the accuracy judgement to user's countenance, avoid the generation of above-mentioned maloperation.
In the present embodiment, human face expression classification is identified using trained facial expression classification model, is improved
To the identification accuracy of human face expression, the correct unlatching of noctilucence screen mode ensure that.
