［ the 1st embodiment ］
The 1st embodiment relates to electronic equipment of the present invention.
Fig. 1 is the schematic oblique view of the electronic equipment in the 1st embodiment.Fig. 2 is schematic oblique view when electronic equipment is hypothetically decomposed.
Position detection part 20 for example consists of the touch panel of electrostatic capacity type, configuration overlappingly on display part 10.For example, by showing at display part 10 under the state with the corresponding various icons of function of electronic equipment 1, with the finger touches touch panel and select icon, slide on touch panel and point such action, the action that can make electronic equipment 1 be expected.
Like this, electronic equipment 1 is the electronic equipment of the portable use of the action be scheduled to accordingly with the movement that is positioned over the biosome on display part 10.And as described later, the same operation of operation during by the action with electronic equipment is scheduled to, can generate Biont information.
Although be to design according to the setting of line sensor 43, image pickup part 40 can be made as at least one the structure in shooting near infrared light image and visible images.Particularly, image pickup part 40 can be made as the structure of shooting near infrared light image, the structure of shooting visible images or the structure of shooting near infrared light image and visible images.By shooting visible images, the pattern of the organism surface that the fingerprint for example of can making a video recording is such.In addition, by shooting near infrared light image, for example finger vena pattern of can making a video recording.Here, the situation of image pickup part 40 shooting near infrared light images described.
In electronic equipment 1, irradiate near infrared light from display part 10, the near infrared light image of the near infrared light of image pickup part 40 shootings based on reflecting in vivo.Dispose the Lighting Division 30 that irradiates light at the back side of display part 10, the near infrared light sent from display part 10 irradiating illumination sections 30.
The limit that will be positioned at the light guide plate 31 of 11 limit, viewing area 12A side means with symbol 32A, and the limit that will be positioned at the light guide plate 31 of limit 12B side means with symbol 32B.Similarly, the limit that will be positioned at the light guide plate 31 of 11 limit, viewing area 12C side means with symbol 32C, and the limit that will be positioned at the light guide plate 31 of limit 12D side means with symbol 32D.
The 1st light source 33A, 33B are disposed at the end face of the limit 32A side of light guide plate, and the 1st light source 33C, 33D are disposed at the end face of the limit 32C side of light guide plate.The visible ray that the 1st light source 33 occurs is from the end face of light guide plate 31 to the interior incident of light guide plate 31, and after the interior propagation of light guide plate 31, from front surface (with the display part 10 face in opposite directions) outgoing of light guide plate 31, from back side illuminaton display part 10.
Send the 2nd light source 34(34A, the 34B of near infrared light) be disposed at the part that approaches image pickup part 40, so that the detection of the near infrared light reflected in vivo etc. is carried out well.In illustrated example, light source 34A is disposed at the end face of the limit 32A side of light guide plate 31, and light source 34B is disposed at the end face of limit 32B side.The near infrared light that the 2nd light source 34 occurs also from the surface feeding sputtering of light guide plate 31 in light guide plate 31, after the interior propagation of light guide plate 31, from the front surface outgoing of light guide plate 31, from back side illuminaton display part 10.
Therefore, from display part 10 towards operator's side, except the visible ray that the 1st light source 33 occurs, also irradiate the near infrared light that the 2nd light source 34 occurs.
Because near infrared light can't detect by an unaided eye, so the demonstration of 34 pairs of images of the 2nd light source is without contribution.Such viewpoint from the reductionization of power consumption, the 2nd light source 34 preferably is controlled as when shooting near infrared light image and is set to illuminating state, in the situation that in addition become the light-off state.
Above, the structure of electronic equipment 1 has been described.Next, explain according to from the information of position detection part 20 with from such actions such as Information generation Biont information of image pickup part 40.For convenience of description, here, should refer to generate comprise from the minor details of the second finger (forefinger) to the Biont information of vein pattern of joint.
Fig. 3 is the schematic process flow diagram of the action for electronic equipment is described.
If such " need to obtain Biont information " application such as authentication, registration is started, for example on picture, impelled the operator to carry out the demonstration of " to cross the mode of camera watch region, making finger from viewing area to the camera watch region Slideslip " such action.
And electronic equipment 1, for example, every the predetermined time interval delta T, obtain positional information and the one dimension image information of finger, is stored in the memory storage (step S1) that for example control part 50 possesses.With reference to Fig. 4 to Fig. 7, be elaborated.
(A) of Fig. 4, (A) of Fig. 5 and (B) and Fig. 6 (A) and (B) be the schematic planimetric map of the action while for explanation, obtaining Biont information.
Original state after the schematically illustrated placement finger 100 of (A) of Fig. 4.If place finger 100 on display part 10, for example point the coordinate figure of 100 contact portion, as positional information, by position detection part 20, detected.If perceiving finger 100 contacts, for example according to the indication of control part 50, between predetermined certain hour (more specifically, enough pointing for 100 times of crossing camera watch region 44 in common action), the 2nd light source 34 in Lighting Division 30 is set to illuminating state.
The figure in the A ﹣ A cross section shown in (B) schematically illustrated Fig. 4 of Fig. 4 (A).In addition, in diagram, Fig. 4 (B) is enlarged drawing.In addition, display part 10 and position detection part 20 are meaned as one.And then, schematically illustrated Lighting Division 30, image pickup part 40.The circuit substrate of schematically illustrated installation control part 50 grades of the part meaned by symbol PCB in addition.
Irradiate near infrared light from Lighting Division 30, to irradiate finger 100.Near infrared light is in finger 100 internal reflections, and its part is towards display part 10 sides.Move and be positioned on camera watch region 44 if point 100, can access and the corresponding one dimension image information in this position by image pickup part 40.
Control part 50 every predetermined time interval delta T obtain information (particularly, coordinate figure (X, Y)) from position detection part 20 and, from the one dimension image information of image pickup part 40, be stored in the memory storage of control part 50.For convenience of description, here, to carry out obtaining of N coordinate figure (X, Y) and one dimension image information etc. and to describe.In addition, by the n time (wherein, n=1,2,3 ..., N) (X for coordinate figure
n, Y
n) mean.
The operator will point 100 and move to directions X, so that state is from the state shown in Fig. 4 (A) to the state transition shown in Fig. 6 (B).(A) of Fig. 5 is the schematic diagram that the state of (n ﹣ 1) inferior data in obtaining is shown, and (B) of Fig. 5 is the schematic diagram that the data of the n time state in obtaining is shown.
In order to contribute to the understanding of invention, although be the item associated with ensuing (step S2) shown in Fig. 3, the method for solving of the translational speed that explanation is pointed now.At (A) of Fig. 5 and (B), point 100 contact point on display part 10, so position detection part 20 can carry out the detection of coordinate figure.The mistiming of (A) of Fig. 5 and (B) of Fig. 5 is above-mentioned Δ T, so the speed component VX of the directions X of the translational speed of finger can pass through VX=(X
n﹣ X
n-1the such formula of)/Δ T is obtained.In addition, although not shown, the speed component VY of Y-direction can pass through VY=(Y
n﹣ Y
n-1the such formula of)/Δ T is obtained.
In addition, in the situation that n=1, not with (X
n-1, Y
n-1) corresponding data, so can not carry out above-mentioned speed component VX, the calculating of VY.But, when the one dimension image information is expanded into to two-dimensional image information, the velocity information while not needing n=1, so do not have special obstacle.
In addition, for convenience of description, the speed component VY of Y-direction is fully little with respect to the speed component VX of directions X, when the one dimension image information is expanded into to two-dimensional image information, can ignore the impact of speed component VY.
If point 100 further to the image pickup part side shifting, point 100 contact point and change to outside display part 10.By this state shown in (A) of Fig. 6, by final state shown in (B) of Fig. 6.Do not detect the coordinate figure of the contact point of finger 100, so in this case, replace coordinate figure, obtain data and the one dimension image information of the situation of representation case as " can't detect contact point ", be stored in memory storage and get final product.
Although be the item associated with ensuing (step S2) shown in Fig. 3, the method for solving of the translational speed of finger in this case is described here.Usually can think, make to point 100 translational speeds during from from the state shown in Fig. 4 (A) to the state transition shown in Fig. 6 (B), except initial stage and latter stage, be basic fixing.In other words, the speed component VX of above-mentioned directions X, when finger 100 moves, can be considered as and certain fixed value VX
constabout equally.Fixed value VX
constvalue, for example, can calculate average velocity by the variation of the X coordinate figure according to finger 100 contact point and obtain.The speed component VY of Y-direction too.
Perhaps, can't detect the translational speed of later finger 100 of moment of contact point, can be considered as with the last state that can detect contact point in translational speed about equally.For example, if what establish the coordinate figure that can detect contact point is that n ' is inferior for the last time, can have
the speed component VY of Y-direction too.
Above, illustrated in (the step S1) shown in Fig. 3 to obtain what kind of data.In addition, above-mentioned " Δ T ", the value of " N " get final product according to the suitable settings such as specification of electronic equipment 1.
Next, electronic equipment 1 expands into two-dimensional image information (step S2) by obtained one dimension image information, extracts vein pattern (step S3) from two-dimensional image information, extract minutiae etc. (step S4), as required carry out (step S5s) such as registration process, authentication processing thereafter.
According to the coordinate information of the finger 100 that is stored in memory storage, calculate above-mentioned fixed value VX
const.As shown in Figure 7, the one dimension image information that (n-1) is inferior and the one dimension image information of the n time, can regard as on directions X at a distance of (VX
const* Δ T) made a video recording and the data that obtain in position.Thus, N one dimension image information can be expanded into to two-dimensional image information (step S2).
In addition, the method that N one dimension image information is expanded into to two-dimensional image information is not limited to this.For example, also can adopt following method: having detected under the such condition of the contact point of pointing 100, calculate separately VX=(X
n﹣ X
n-1)/Δ T, used its value, and after can't detect the moment of contact point, use can detect the value of the translational speed under the last state of contact point.
In addition, in the situation that can not ignore the impact of the speed component VY of Y-direction, consider speed component VY, the one dimension image information is expanded into to two-dimensional image information and get final product.
Next, carry out extracting the image processing (step S3) of vein pattern from resulting two-dimensional image information.The method that image is processed without particular limitation of.For example, suitable selection from use so known image processing method such as method of difference, the method for zero crossing, the method for service range wave filter (range filter), get final product and carry out the image processing.Thus, can extract vein pattern.
Thereafter, for example, the features such as the position of the take-off point of the blood vessel in the extraction vein pattern, direction, carry out required datumization (step S4).The method of datumization without particular limitation of.For example with the finger print identifying technology similarly, can enough extraction details (tiny branch, the part of disconnection) such method carry out.
Next, carry out as required (step S5) such as registration process, authentication processing.In the situation that vein pattern is carried out to new registration, according to the action of the Biont information register 52 shown in Fig. 2, carry out the such processing of the new registration of the data of vein pattern is got final product.The method of registration process without particular limitation of, according to the specification of electronic equipment 1 etc., from for example known method, select suitable method to use and get final product.In addition, in the situation that carry out the authentication of vein pattern, according to the action of the Biont information authentication department 53 shown in Fig. 2, with the data of registered vein pattern, contrasted, carry out authentication processing and get final product.The method of authentication processing without particular limitation of, according to the specification of electronic equipment 1 etc., for example from known method, select suitable method to use and get final product (step S5).
Above, illustrate according to from the information of position detection part 20 with from such actions such as Information generation Biont information of image pickup part 40.
In the electronic equipment of the 1st embodiment, the position detection part of touch panel etc. is also used as the position transducer generated for Biont information, so add Biont information generating unit etc. by the additional wire sensor and to control part, can realization obtain the function of Biont information.Therefore, can carry out miniaturization, and can realize cost degradation.
Common action while making the such action of finger sliding with action that electronic equipment is expected on display part is identical.Therefore, electronic equipment possesses when being registered, authenticating such action, can not make operator's such advantage that do not feel well.
In addition, only the light source of the additional generation of Lighting Division near infrared light used to the demonstration of image, just can irradiate near infrared light to biosome.Therefore, do not need to be provided for separately the irradiation unit of the near infrared light of shooting.
And then, when image pickup part is obtained the one dimension image information, camera watch region is pointed covered state.Therefore, the electronic equipment of the 1st embodiment also possesses the such advantage of impact of the ambient light that is difficult to be subject to hinder authentication etc.
Above, according to preferred implementation, the present invention has been described, but has the invention is not restricted to this embodiment.The concrete structure of the textural element of the electronic equipment in embodiment, structure are illustrations, can change aptly.
For example, in the situation that be made as the structure of the pattern of the such organism surface of shooting fingerprint, the structure that is made as image pickup part detection visible ray gets final product.In this case, by making near display part image pickup part, become for example white displays, can irradiate visible ray to biosome.
