In the concrete realization, for different touch screens, a corresponding report point threshold value can be set, using the report point threshold value as
Neighbouring range is determined as reporting point critical range by benchmark.
In a frame touch data, in the sampled point reported within the scope of point critical, sampling changing value is lower, it may be possible to

In a frame touch data, using the sampling changing value of sample reference point as references object, compares other and adjacent adopt

Referring to Fig. 2, the step of showing the sampling compensation method of another touch data of one embodiment of the invention stream
Cheng Tu can specifically include following steps:
Step 201, touch data is acquired.
It wherein, include multiple sampled points in touch data.
Referring to Fig. 3 A to Fig. 3 D, a kind of exemplary diagram of touch data of one embodiment of the invention is shown.
In Fig. 3 A to Fig. 3 D, each numerical value is the position represented where collection point, also represents the collection point
Diff (sampling changing value).
The touch-control that Fig. 3 A holds mobile terminal by one hand of user, another hand is triggered with 3 finger touching touch screens
Data, the diff (i.e. boxed area in Fig. 3 A) of the collection point touched by user's finger, maximum value all 600 or more, count
It is larger according to the amplitude of variation.
Fig. 3 B- Fig. 3 D is that mobile phone prevents from pondering in plastics, and a hand uses 4,3,2 finger touching touch screen institutes respectively
The touch data of triggering, the diff (i.e. boxed area in Fig. 3 B- Fig. 3 D) of the collection point touched by user's finger, maximum value
Substantially 200 hereinafter, the amplitude of data variation is smaller.
Step 202, the first ratio, the second ratio are taken respectively on the basis of preset change threshold, obtains critical report point
Lower limit value, critical report point upper limit value.
Step 203, if the sampling changing value of the sampled point is located at the critical report point lower limit value and the critical report point
Between upper limit value, then sample reference point is set by the sampled point.
In embodiments of the present invention, the sampling changing value of sample reference point be can be obtained into critical report multiplied by the first ratio
Point lower limit value.
By the sampling changing value of sample reference point multiplied by the second ratio, critical report point upper limit value can be obtained.
Wherein, the first ratio is greater than 1 less than 1, second ratio, and therefore, critical report point lower limit value is less than a report point threshold value, critical
Report point upper limit value is greater than report point threshold value, to form report point critical range.
Under normal circumstances, critical report point upper limit value is less than finger report point lower limit value.
The finger report point lower limit value is the characteristic for user's finger, by report point threshold value multiplied by a certain multiple number obtained
Value.
For example, setting sampled point as X, report point threshold value is Limit, and finger report point lower limit value is generally higher than 3*Limit, then first
Ratio is set as 0.7, and the second ratio is set as 2, and using diff as sampling changing value, then the sampling changing value of X is expressed as diff (X),
2*Limit < diff (X) < 0.7*Limit, then be defined as sample reference point for X.
By the sampling changing value of the sampled point in a frame touch data and critical report point lower limit value, critical report point upper limit value into
Row compares, and therefrom the sampling changing value between critical report point lower limit value and critical report point upper limit value, is set to sample
Central point.
Step 204, the sampled point adjacent with the sample reference point is determined.
Step 205, judge sampling amplitude of variation between the sample reference point and the adjacent sampled point whether
In preset amplitude range；If so, thening follow the steps 206.
In embodiments of the present invention, by a certain range of sampled point of distance samples reference point, referred to as adjacent sampling
Point.
For example, 0 sampled point of distance samples reference point, 1 sampled point of distance samples reference point, distance samples reference point 2
A sampled point etc., the embodiments of the present invention are not limited thereto.
The sampling changing value of sample reference point is compared with the sampling changing value of neighbouring sample point, obtains sampling variation
Amplitude.
If sampling amplitude of variation in the amplitude range of setting, indicate that sampling amplitude of variation is smaller, it is believed that this is adopted
Sample reference point is the sampled targets point that touch-control triggers under non-holding state.
In one embodiment of the invention, using sample reference point as benchmark, the first range, the second range are marked off,
The sampled point adjacent with sample reference point includes sampled point adjacent in the first range, sampled point adjacent in the second range.
Wherein, the first range is less than the second range.
In one example, the first range is as shown in the table:
| * | ||
| * | A | * |
| * |
Second range is as shown in the table:
| * | * | * |
| * | A | * |
| * | * | * |
Wherein, " A " represents sample reference point, and " * " represents adjacent sampled point.
In embodiments of the present invention, step 205 may include following sub-step:
Sub-step S11 takes third ratio, the 4th ratio on the basis of the sampling changing value of the sample reference point, obtains
Obtain the first change threshold, the second change threshold.
By the sampling changing value of sample reference point multiplied by third ratio, the first change threshold can be obtained.
By the sampling changing value of sample reference point multiplied by the 4th ratio, the second change threshold can be obtained.
Wherein, third ratio and the 4th ratio are respectively less than 1, also, third ratio, less than the 4th ratio, therefore, first becomes
Change threshold value less than the second change threshold.
Sub-step S12, in second range in adjacent sampled point, statistic sampling changing value is greater than described second and becomes
Change the quantity of the sampled point of threshold value.
Sub-step S13, judges whether sampled point adjacent in first range is greater than or equal to the first variation threshold
Value, also, the quantity is greater than or equal to preset amount threshold；If so, executing sub-step S14.
Sub-step S14 determines the sampling amplitude of variation between the sample reference point and the adjacent sampled point pre-
If amplitude range in.
If the sampling changing value of adjacent sampled point is greater than or equal in the first range around sample reference point A
First change threshold, also, in the second range around sample reference point A, sampling changing value is greater than or equal to the second variation
The quantity of threshold value, adjacent sampled point is greater than or equal to amount threshold, it may be considered that sample reference point and adjacent sampling
For sampling amplitude of variation between point in preset amplitude range, i.e. sampling amplitude of variation is smaller.
For example, setting sample reference point as A, third ratio is 0.25, and the 4th ratio is 0.5, is changed using diff as sampling
Value is greater than or equal to 0.25*diff (A) in the diff of 4 adjacent sampled points of the identical row and column of A, in 8 adjacent samplings of A
In point (8 sampled points of remaining in nine grids), the number of sampled point of the diff more than or equal to 0.5*diff (A) is greater than or equal to
3, it may be considered that the sampling amplitude of variation between sample reference point and adjacent sampled point is in preset amplitude range.
Step 206, the sampled targets point of the touch-control triggering under non-holding state is determined by the sample reference point.
In the concrete realization, third range can be determined using sampled targets point as benchmark, i.e., by distance samples target point
The range delineation of certain distance is third range (third range may include sample reference point).
By the sampled point within the scope of third labeled as the sampled targets point that touch-control triggers under non-holding state.
In one example, third range is as shown in the table:
| # | # | # |
| # | A | # |
| # | # | # |
Wherein, " A " represents sample reference point, and " # " represents the sampled point (including A itself) within the scope of third.
Step 207, sampling compensation is carried out to the sampled targets point.
In the concrete realization, the 5th ratio can be taken to the sampling changing value of sampled targets point, and it is compensated to obtain sampling
Sample changing value.
Wherein, the 5th ratio is greater than 1, such as 1.5 (compensating 50%)；The compensated sampling changing value of sample reference point sampling
At least more than report point threshold value.
