The quality uniformity and clarity of perceptual image.
More specifically, in the embodiment of the present invention, can be brightness rule and emergent light brightness change rule on the contrary,
It is exactly the brightness law of character graphics displaying emergent light brightness change rule corresponding with RI of optical finger print touch area on the contrary, in this way can be real
Now be adapted well with RI so that the light of optical finger print touch area by camera lens reach sensor pixel induction after,
The adjacent area brightness ratio of sensor can reach 1, i.e., when center exposure reaches target influence value, from centre to side
The induction value of each pixel of edge will all be up to target value, show the consistent level of overall brightness, and there is no inductions not
The problem of foot.
In the embodiment of the present invention, it (can be finger that the terminal, which further includes for receiving the imaging sensor of the touch information,
Line sensor), the absolute value of the difference of the brightness value of any two position is less than preset value in described image sensor.
It is, the light of optical finger print touch area by camera lens reach sensor pixel induction after, sensor
Adjacent area brightness ratio can be greater than threshold value, and it is consistent horizontal (brightness uniformity) to show overall brightness as far as possible.
The display control method provided in an embodiment of the present invention is further described below, touch control operation is with user
Finger generate pressing operation for.
In view of the above technical problems, it is contemplated that the light that fingerprint adopts graph region sending at present is single brightness color lump, by hand
Before referring to pressing, the screen of terminal shows fingerprint location icon, after the finger of user is pressed into the target icon of operation fingerprint, screen
Curtain will issue the circular light spot of green or white, which is used for the transmitting light source source of photoelectricity fingerprint recognition；Currently, the hair
Penetrate hot spot brightness be it is single uniform, formation is uniform light spots light source；
And the uniform light spots light source is after optical lens (LENS), because of the heterogeneity of the light receiver of camera lens, into
The light intensity for entering the surface of fingerprint sensor is also not uniform, it will occur intermediate strong, edge is weak, from centre to edge by
The weak rule of gradual change, here it is the relative illumination index of camera lens, brightness ratio, that is, camera lens phase of the peripheral brightness with respect to center
To illumination (RI:relative illumination) index, by the convex lens principle features of camera lens it is found that its (RI) can not
Reaching 100%, for example reaches 60%, this just will appear the case where uniform light spots light-source brightness is not adapted to camera lens RI index, when
When fingerprint sensor exposes, it will the inhomogeneities i.e. fingerprint image of picture quality is caused intermediate bright, the dark situation in edge occur；

Method does not use uniform light spots mainly, but uses the gradual change hot spot being adapted to RI, and it is uniform can to significantly improve the picture quality
Property, improve intermediate the problem of arriving edge brightness dimmed step by step (intermediate excessively bright, edge is dark), improve picture quality, improves fingerprint and know
Not rate.
Specifically, assuming that optical finger print touch area is original pure color brightness hot spot in existing scheme, brightness hot spot can be with
It is pure white or other colors, below by taking white hot spot as an example:
When original pure white hot spot is after optical lens, because camera lens receives the heterogeneity of light energy, emergent light
Brightness hot spot on the surface of fingerprint sensor will become intermediate bright, successively the dark feature in edge.
When gradually for dimmed light after sensor pixel induction, intermediate sense will be presented in the induction value of each pixel for this
It should be worth greatly, gradually become smaller (as shown in the table) to the periphery, when intermediate pixel reaches target influence value, centre incudes to edge
Value parameter is but gradually reduced, intermediate influence value 3200, indicates brightness highest, and edge is minimum, occurs as soon as under-exposure, if continued
Exposure just will appear intermediate overexposure.
Sensor pixel photoinduction severity parameter value sample table
According to the sensor sensing value of the above pure color hot spot, so as to obtain the photosensitive from center of the optical system lens
The dampening information changed to edge brightness, such as attenuation ratio, if brightness value from the center to the periphery is followed successively by A1, A2,
A3…An；Then brightness change ratio K1=A2/A1；K2=A3/A2 ... Kn=An/An-1.
In order to make up the problem weak because of peripheral luminance shortage bring picture signal amount, this programme uses gradual change hot spot,
The brightness rule of the hot spot is just opposite with the emergent light brightness change rule.
Concrete operations can be to adjust the grayscale parameter of screen intensity hot spot, realize among the hot spot secretly, from centre to edge
Gradually brighten.
If the polishing intensity gray scale at center to edge is followed successively by B1, B2, B3 ... Bn；The then corresponding brightness change of grayscale value
Ratio K ' n=1/Kn=Bn/Bn-1, it can the rule for pushing down several times rate successively lightens hot spot.
Obviously, using the above gradual change hot spot, the Spot lights are after camera lens reaches sensor pixel induction, sensor
Adjacent area brightness ratio An/An-1=Kn × (1/Kn)=1, i.e., when center exposure reaches target influence value, from
The intermediate induction value to each pixel in edge will all be up to target value, show the consistent level of overall brightness, Bu Huicun
In the problem that induction is insufficient.
From the foregoing, it will be observed that scheme provided in an embodiment of the present invention is mainly by by the uniform single of current photoelectricity fingerprint hot spot
