Embodiment one
Fig. 1 is a kind of process that product lamp bar brightness adjusting method is shown for mirror surface that the embodiment of the present invention one provides
Figure, the present embodiment are applicable to the case where local modulation mirror surface shows the lamp bar brightness of product, and this method can be by the present invention
One kind that embodiment provides shows that product lamp bar brightness regulating apparatus executes for mirror surface, the device can be used software and/or
The mode of hardware is realized.With reference to Fig. 1, this method can specifically include following steps:
S110, when user's face and mirror surface show that the distance between lamp bar of product is less than pre-determined distance, according to user
The image of face determines the eyeball fixes direction of user.
Specifically, mirror surface shows product band illumination functions, and realizes the lamp bar of illumination functions and independently luminous hair can be used
Optical diode (Light-Emitting Diode, LED) is constituted, each light emitting diode is known as light-emitting particles.In order to obtain
Preferable illuminating effect is obtained, lamp bar can be circular ring type lamp bar or linear type lamp bar, and lamp bar is mounted on the side that mirror surface shows product
In boundary.Optionally, mirror surface shows that product can be illumination vanity mirror, is also possible to the intelligent terminal etc. with mirror surface display function.
When user shows product using mirror surface, user shows product according to demand by adjusting the position of itself or mirror surface
Position change user and mirror surface show the distance between product, wherein show that the corresponding function of product selects to use according to mirror surface
Family face and mirror surface show the distance between product.When user's face and mirror surface show that the distance between the lamp bar of product is less than in advance
If apart from when, the direction of gaze of user eyeball is determined according to the image of user's face, optionally, the image of user's face can lead to
The camera being integrated in mirror surface display product is crossed to obtain.
Optionally, the distance between product can be shown using infrared distance sensor detection user's face and mirror surface, in advance
If distance can take 30 centimetres, when detecting that user's face and mirror surface show that the distance between product is less than pre-determined distance, then
Show that user closely shows product using the mirror surface.
S120, current environment target luminance is obtained.
Specifically, the light that mirror surface shows product local environment can be detected with light intensity sensor (referred to as optical flame detector)
Brightness, since mirror surface shows that product itself has luminous lamp strip, lamp bar light influences whether the accuracy of optical flame detector detection data.Cause
This, needs the environmental light brightness for detecting optical flame detector to calibrate, to obtain current environment target luminance, wherein environment

Figure, the present embodiment on the basis of the above embodiments, to " determining the eyeball fixes direction of user according to the image of user's face "
It is optimized.With reference to Fig. 2 a, this method can specifically include following steps:
S210, when user's face and mirror surface show that the distance between lamp bar of product is less than pre-determined distance, obtain user
The gray-value image of eye areas, wherein the eye areas includes black eyeball and white of the eye region.
Specifically, when user's face and mirror surface show the distance between lamp bar of product less than pre-determined distance, to acquisition
To the face-image of user handle, processing method can select the face recognition algorithms in image recognition algorithm, such as:
It normalizes the Face datection algorithm under RGB color or is based on the people of PCA (Principal Component Analysis)
Face recognizer etc., wherein R, which represents red R ed, G and represents green Green, B, represents blue Blue.Identification camera capture in real time
Face in image is positioned eye image using integral projection algorithm etc. and is intercepted, the figure of eye areas is obtained with this
Picture.
Gray proces are carried out to the image of eye areas, obtain the gray-value image of eye areas, wherein eye areas packet
Include black eyeball and white of the eye region.Optionally, the size of eye areas accounts for the ratio of entire face-image in usual situation
Under can one substantially in the range of, can according to the principle choose eye areas image.Fig. 2 b shows a kind of eyes area
Domain, 270 represent black eyeball, and 280 represent white of the eye region, it should be noted that white of the eye region said herein is one
A rough signal because may user it is personal due to (such as customization heavy make-up leads to the image of informer or eye shadow
It is presented on white of the eye region) to get the eye areas of user be not accurate white of the eye region.
Optionally, the gray value of the pixel of black eyeball is low, the pixel of white of the eye region and skin area
Gray value is high.It, can be by pixel structure of the intensity value ranges in the first default intensity value ranges in a specific example
At region be defined as black eyeball, wherein the first default intensity value ranges be 0~70, intensity value ranges second are preset
The region that pixel in intensity value ranges is constituted is defined as white of the eye region or skin area, wherein the second default gray value
Range is 180~255.
Illustratively, the method for discrimination of eye areas can also be accomplished by the following way, and detect black eyeball
Around have pixel in the second default intensity value ranges of the first preset quantity after, and occur the of the second preset quantity
Pixel in one default intensity value ranges then shows that the point in the first default intensity value ranges of second preset quantity is eyelash
The pixel of hair image.Therefore, eye areas can be determined by eyelashes region, foregoing description be to for one eye eyeball
For, the determination method of the eye areas of another eye is identical, and details are not described herein.When the eyes area of two eyes has been determined
Behind domain, then the eye areas of user can be determined.Optionally, the eye areas of user may comprising except two parts eye areas with
Outer skin area.
S220, the zonule that the eye areas is divided into setting quantity according to the central point of the black eyeball.
Specifically, the position of iris, iris area can be navigated to by the gray value detection of the image of eye areas
Domain is black eyeball, and the center of iris is pupil.Eye areas is divided into setting according to the central point of black eyeball
The zonule of quantity.In a specific example, by taking the one eye eyeball of user as an example, using the central point of black eyeball as
Coordinate origin establishes rectangular coordinate system, and eye areas is divided into 4 regions, Fig. 2 c show a kind of eye areas by quadrant into
The result of row display, wherein 290 be eye areas, 291 is black eye ball upper right side (first quartile), 292 is black eye ball upper left side
(the second quadrant), 293 are black eye ball lower left (third quadrant) and 294 are black eye ball lower right (fourth quadrant).
S230, the pixel number for being less than default gray value in each zonule is counted respectively.
Specifically, behind the zonule that eye areas is divided into setting quantity according to the central point of black eyeball, needle
