Device 260 can calculate center, center of gravity or the meansigma methodss in clear zone 1012 after image 1010 is received, and this is object 502 in shadow
As the position in 1010.Fig. 8, Fig. 9 and Figure 10 are refer to, to try to achieve the angle α 1 of dotted line 582 and sensing route 902, can be by shadow
Some equal portions, such as 90 equal portions are averagely divided into as 1010.Each equal portions represent 1 degree of angle, so the right margin of image 1010
For 0 degree of angle, and left margin is 90 degree of angle.When center, center of gravity or meansigma methodss when object falls in image 1010, you can right
The angle [alpha] 1 representated by the position should be gone out.For example, 1018A represents angle [alpha] 1 for 45 degree, and 1018B represents angle [alpha] 1 for 30
Degree, 1018C represents angle [alpha] 1 for 75 degree.If during without the just corresponding angles angle value of integer, can with interpolation calculation it.And phase Tongfang
Method can also try to achieve angle beta 1.
Fig. 8 is refer to, using known A point coordinates value and angle [alpha] 1, you can using the oblique formula (point-slope of point
Form the straight line equation of sensing route 902) is tried to achieve；In the same manner, it is possible with B point coordinates value and angle beta 1 tries to achieve sensing route
904 straight line equation.Therefore, processor 260 just can calculate the two sensing routes 902,904 intersection point, and then try to achieve it is right
As 502 coordinate.This object coordinate computational methods, are exactly so-called two lines intersection method.In addition, portable electronic input equipment
200 may also be employed additive method, such as trigonometric function method calculating the coordinate of object 502, because the method widely makes
In for existing optical touch control system, here is just repeated no more.Additionally, using above-mentioned teaching, this area has generally to be known
The knowledgeable ought know that this portable electronic input equipment 200 can be used with multi-point touch (multi touch).
In addition, in the visual field of the first CIS or the second CIS in addition to object 502 to be measured, the visual field
It is likely to can the presence of other objects at a distance, and these objects can also reflect infrared ray and interfere with portable electronic input equipment
200 operation, therefore the brightness of the light that can be reflected using object is being screened.For example (but being not limited),
The predeterminable brightness threshold value of processor 260 or a brightness range, and by the first CIS and the second CIS institute
The brightness value of each pixel (pixel) in the image of acquisition carries out detection screening.If the brightness value of a pixel exceedes default
Brightness threshold value falls in default brightness range, then the brightness value of this pixel meets preset standard.In this way, sequentially sieve
The brightness value of each pixel in image is selected, then can filter other objects beyond object to be measured 502.
Using above-mentioned explanation, it is known that the scope of aforementioned touch area 590 can reach in theory infinity.However, touch-control
The size in region 590 still can be limited using the mode of software.Referring again to Fig. 8, in touch area 590, by dotted line
582 formed while length be, it is known that and being all endless on length ideal when formed by dotted line 584 and 586 two.
Length to make two sides formed by dotted line 584 and 586 is predetermined length, and processor 260 can be fixed according to different application occasion
The different touch-control scope of justice.For example, when portable electronic input equipment is used as a virtual mouse, then in first
The defecation of the touch area 590 in the front of 230 and second image sensing module of image sensing module 240 can be real according to user operation
The use habit scope of body mouse and defined, be e.g. defined as 15cm × 15cm (i.e. 582 length of dotted line × dotted lines 584
Length) size touch-control scope.Or, processor 260 can immediately be defined using the size of object image with the relation of distance
The predetermined length of dotted line 584 and 586, is possible with the brightness of reflected light of object image defining this predetermined length, or
Define the predetermined length of dotted line 584 and 586 immediately with reference to this two kinds of modes, and processor 260 will be built in the mode of definition
In the middle of the software for being adopted or firmware.Consequently, it is possible to touch area 590 just can present four sides with predetermined area size
Shape touch-control scope.
Hold above-mentioned, in the case where touch area 590 has predetermined area size, it is right that processor 260 can be calculated first
As 502 coordinate, then judge whether object 502 is located in touch area 590 again.When object 502 is located in touch area 590
When, processor 260 can just pass through the coordinate of the object output 502 of communication interface 560.Certainly, processor 260 can also first be calculated
Go out the coordinate of object 502, and the coordinate of object 502 is exported by electronic installation extremely by communication interface 220, to allow this electronics dress
Put and voluntarily judge object 502 whether in touch area 590, and then decide whether to be used.

Outer smooth filtering apparatus 234, optical glass group 236, infrared light emission device 238 (this figure is not illustrated) and (this figure of optical glass 239
Do not illustrate) arrange also with this predetermined angle theta 3.Wherein, the set-up mode of infrared light emission device 238 and optical glass 239
The direct of travel that infrared light must be enabled is roughly parallel to real work table plane 802.Due to this predetermined angle theta 3 be less than
90 degree, therefore the visual field of the first CIS 232 is limited distance.That is, the first CIS 232 is sensed
Image the depth of field be limited distance.

Lens set 246, infrared light emission device 248 and optical glass 540 are learned also in the way of shown in Figure 12 arranging.
Referring again to Fig. 8, because the visual field of the first CIS 232 and the second CIS 242 is by infinity
Change into limited distance, it may thus be appreciated that in touch area 590, the length on two sides formed by dotted line 584 and 586 be according to
Define according to the first CIS 232 farthest visual field to be sensed with the second CIS 242.And CIS
The farthest visual field that can be sensed can refer to the mode shown in Figure 12 to be calculated.In fig. 12, D is expressed as the first image sensing
The farthest visual field (i.e. the length of dotted line 584 or 586) that device 232 can be sensed, H is expressed as the height of the first CIS 232,
θ 2 is expressed as angle.Relation between D, H, θ 2 is represented by the formula D=H/tan (θ 2) in figure, and θ 3 (see Figure 11) adds θ 2
It is for 90 degree of angle.For example, H is 5mm, and θ 2 is 1.91 degree of angle, then it be then H/tan (θ 2) that the D Jing formula is calculated, as
About 150mm.
