Fig. 2A is a kind of flow chart of ambient light measurement method according to another exemplary embodiment, the environment flash ranging
Amount method is applied in the electronic equipment comprising touch-screen, and optical sensor is evenly distributed with touch-screen, as shown in Figure 2 A, the ring
Border photo measure method comprises the following steps.
In step 201, the operating area for the touch control operation that operating body is acted on touch-screen is obtained.
Wherein, operating body can be the finger of user or the palm of user, can also be other portions of user
Position, the present embodiment are not construed as limiting.
Multiple touch control units are evenly distributed with touch-screen, when touch control operation acts on the touchscreen, by touch control operation
The capacitance of the touch control unit of covering can change, the area that the touch control unit that electronic equipment changes capacitance is formed
Domain is defined as the operating area of touch control operation.The touch control unit that capacitance changes in the present embodiment is referred to as contact.
In the present embodiment, optical sensor is evenly distributed with touch-screen.It refer to the distribution of the optical sensor shown in Fig. 2 B
Schematic diagram, optical sensor 210 is represented with round dot, and control chip 220 is represented with the rectangle of the top, and wire 230 is represented with lines,
Pixel color lump 240 is represented with each rectangle that lower section is distributed, wherein, each optical sensor 210 is connected to control by wire 230
Chip 220.
Because operating body is in contact with operating area, therefore, for the optical sensor in operating area, originally
The ambient light operated member that these optical sensors should be injected is blocked, and the measured value that these optical sensors measure not is ambient light
Intrinsic brilliance value, so as to influence the accuracy of the brightness value of measuring environment light.In addition, when light source is located at the top of electronic equipment
When, the operating body irradiated through ambient light can form shade on the touchscreen, the measured value that the optical sensor in shade measures
It is not the intrinsic brilliance value of ambient light, can influences the accuracy of the brightness value of measuring environment light yet.Therefore, in measuring environment light
Brightness value when, it is necessary to exclude the measured value of these optical sensors.
In the present embodiment, the region that optical sensor that the ambient light operated member of injection is blocked is formed is as failure area
Domain, the failed areas include operating area and shadow region.Because operating body is probably finger, it is also possible to palm, and finger
In operation, caused shade is different with palm, and shade is not according to caused by finger and palm in operation for the present embodiment
With different shadow algorithm is chosen, solve according to identical shadow algorithm come area of failing caused by calculating finger and palm
Domain, the problem of causing the determination inaccuracy of failed areas, the effect for improving the accuracy for determining failed areas is reached.It is right below
The determination method of failed areas illustrates.
In step 202, it is the finger of user or the palm of user according to the area detecting operating body of operating area；When
When operating body is the finger of user, step 203 is performed；When operating body is the palm of user, step 204 is performed.
Because the contact area of finger and touch-screen is smaller, and the contact area of palm and touch-screen is larger, therefore, electronics
Equipment can determine that operating body is finger or palm according to the area of operating area.When actually realizing, can first set
Predetermined area, when the area of operating area is less than the predetermined area, it is finger to determine operating body, performs step 203；Work as operation
When the area in region is more than the predetermined area, it is palm to determine operating body, performs step 204.
In step 203, the failed areas for including operating area is determined according to the first shadow algorithm, performs step 205.
When operating body is finger, because user is generally by the finger tip operation touch-screen of finger, and finger is longer so that
Shadow region is larger caused by finger, therefore, the failed areas that can be set according to this feature.Present embodiments provide two
Kind determines the implementation of the failed areas comprising operating area according to the first shadow algorithm, separately below to both realization sides
Formula is introduced：
In the first implementation, the first predetermined length is obtained, first predetermined length is more than appointing in operating area
Meaning is a little to the distance of the center of operating area；Centered on center, determined according to the first predetermined length comprising behaviour
Make the failed areas in region.
Wherein, the first predetermined length need be more than operating area in any point to the center of operating area away from
From so just can guarantee that and be all located in operating area in failed areas a little.Generally, the first predetermined length can be set
It is larger, such as, 20mm is arranged to, or other numerical value are arranged to, the present embodiment is not construed as limiting to the numerical value of the first predetermined length.
In the present embodiment, the shape of failed areas can also be set.For example the shape of failed areas can be circular, ellipse
Circle, regular polygon, irregular shape etc..When the shape of failed areas is circle, the first predetermined length is the length of radius
Degree；When the shape of failed areas is regular polygon, the first predetermined length is the length of cornerwise half.
It refer to the schematic diagram of the first failed areas shown in Fig. 2 C, in the view on the left of Fig. 2 C, the finger of user is made
For operating body effect on the touchscreen；In view on the right side of Fig. 2 C, region a is the operating area of finger, and the stain in a of region is
The center of operating area, centered on the center, using the first predetermined length as radius, region b, region can be obtained
B is failed areas.
In second of implementation, the operating force for each contact that touch control operation is acted in operating area is obtained,
Operating force is declined into most fast direction and is defined as the oval failed areas of long axis direction generation, the long axis direction is on major axis
First end point point to double-pointed direction, and first end point and the distance of operating area are less than the second end points and operating area
Distance, the oval failed areas includes operating area.
Because the shade of finger is strip, and hence it is also possible to set the failed areas of ellipse., can when realizing
Shadow region is determined with the direction according to finger, failed areas is determined further according to shadow region and operating area.Wherein, finger
Direction can be embodied by operating force.
It refer to the schematic diagram of second of failed areas shown in Fig. 2 D, in the view on the left of Fig. 2 D, the finger of user is made
For operating body effect on the touchscreen；In view on the right side of Fig. 2 D, region a is the operating area of finger, according to the direction of finger
Understand that operating force declines the direction that most fast direction is the straight line where first end point D1 and the second end points D2, length is being determined
After direction of principal axis, the failed areas b of ellipse is generated.
In step 204, the failed areas for including operating area is determined according to the second shadow algorithm.
When operating body is palm, because user is typically to be pressed on the touchscreen with a part for palm so that shadow region
Domain is smaller, therefore, the failed areas that can be set according to this feature.
In the present embodiment, the failed areas of operating area is included according to the determination of the second shadow algorithm, including：It is pre- to obtain second
Measured length；Using the borderline contact of operating area as starting point, stretch out the second predetermined length along predetermined direction, by what is obtained
Each contact area defined is defined as including the failed areas of operating area, and predetermined direction is the center of operating area
Point to the direction of contact.
Wherein, the second predetermined length can set smaller, such as, the second predetermined length is less than the first predetermined length.When
When first predetermined length is 10mm, the second predetermined length could be arranged to 20mm, it is, of course, also possible to which the second predetermined length is set
For other numerical value, the present embodiment is not construed as limiting to the numerical value of the second predetermined length.
It refer to the schematic diagram of the third failed areas shown in Fig. 2 E, in the view on the left of Fig. 2 E, the palm of user is made
For operating body effect on the touchscreen；In view on the right side of Fig. 2 E, region a is the operating area of palm, and the stain in a of region is
The center of operating area, for borderline each contact of operating area, the side of the contact will be pointed to from the central position
To being defined as predetermined direction corresponding with the contact, the contact is stretched out the second predetermined length d along the predetermined direction, will be every
The contact area defined b obtained after individual contact extension is defined as failed areas.
In step 205, the measured value of each optical sensor outside failed areas is obtained；Deleted from all measured values
I measured value and j minimum measured value except maximum, i and j are positive integer；Calculate being averaged for remaining each measured value
Value, the brightness value using average value as ambient light.
Because light source is natural light mostly, ambient light caused by natural light is uniformly to be injected into each optical sensor,
Therefore, the measured value of each optical sensor should be equal or close.When measured value that some optical sensor measures is too high or mistake
When low, it may be possible to which the optical sensor there is a problem that measured value now is also inaccurate, therefore, in measuring environment light
, it is necessary to exclude the measured value of these optical sensors during brightness value.
In the present embodiment, first measured value can be screened, delete i measured value of maximum of which and minimum j
Measured value, then the average value of remaining measured value is calculated, so as to improve the accuracy for the brightness value being calculated.
Wherein, when deleting i maximum measured value and j minimum measured value, one kind is possible to be achieved in that：Will
Each measured value is ranked up according to order from big to small, obtains measuring value sequence；Delete preceding i in the measurement value sequence
Rear j measured value in measured value and the measurement value sequence.
For the ease of simplifying calculating process, illustrated so that touch-screen includes 5 optical sensors as an example, in actual realization
When, the quantity of optical sensor is far longer than 5.Assuming that the measured value that 5 optical sensors measure is respectively N1, N2, N3, N4 and N5,
And N3 ＞ N5 ＞ N2 ＞ N4 ＞ N1, i=j=1, then the brightness value of ambient light=(N2+N4+N5)/3.
In summary, the ambient light measurement method that the disclosure provides, touching on touch-screen is acted on by obtaining operating body
Control the operating area of operation；It is determined that the failed areas comprising operating area, the ambient light for the optical sensor injected in failed areas
Operated member is blocked；According to the brightness value of each optical sensor measuring environment light outside failed areas, it may be determined that operated
The optical sensor that body blocks, so as to which the inaccurate optical sensor of this part measured value be excluded, use remaining light sensing
The brightness value of device computing environment light, solve an optical sensor being arranged in aperture and be easily blocked, the ambient light measured
Brightness value inaccuracy the problem of, reached improve ambient light measurement accuracy effect.
In addition, by the way that when operating body is finger, failed areas is determined according to the first shadow algorithm；It is palm in operating body
When, failed areas is determined according to the second shadow algorithm, can according to finger with palm in operation caused by shade is different chooses
Different shadow algorithms, solve according to identical shadow algorithm come failed areas caused by calculating finger and palm, cause
The problem of determination inaccuracy of failed areas, the effect for improving the accuracy for determining failed areas is reached.
