光学指纹采集装置、便携式电子装置及光学指纹采集方法 Optical fingerprint sensor apparatus, a portable electronic device and the method of optical fingerprint

技术领域 FIELD

[0001] 本发明涉及指纹采集技术领域,尤其涉及一种光学指纹采集装置、便携式电子装置及光学指纹采集方法。 [0001] The present invention relates to a fingerprint technology, and particularly relates to an optical fingerprint acquisition device, the portable electronic device and the optical fingerprint collection method.

背景技术 Background technique

[0002] 光学指纹传感器是一种利用光的折射和反射原理采集指纹的装置。 [0002] The optical fingerprint sensor is refracted and reflected by the light of the principle of a device of the fingerprint. 请参考图1,示出了现有技术一种光学指纹传感器。 Please refer to FIG. 1, there is shown a prior art an optical fingerprint sensor. 所述光学指纹传感器包括光源11、第一透镜12、直角棱镜13、第二透镜14和图像传感器15,光源11和图像传感器15分别与直角棱镜13的两个相互垂直的侧面正对,而第一透镜12位于光源11和直角棱镜13之间,第二透镜14位于直角棱镜13和图像传感器15之间。 The optical fingerprint sensor 11 includes a light source, a first lens 12, right angle prism 13, the second lens 14 and the image sensor 15, light source 11 and the image sensor and the right-angle prism 15 are two mutually perpendicular side surfaces 13 facing, while the first a light source 11 and lens 12 is positioned between the right-angle prism 13, a second lens 14 positioned between the right angle prism 15 and the image sensor 13.

[0003] 在进行指纹采集时,手指16通常压盖在直角棱镜13上表面。 [0003] During fingerprint, finger 16 is generally rectangular prism 13 on the lid surface. 光源11发出的平行光线通过第一透镜12之后到达直角棱镜13的一个侧面,然后到达棱镜13的上表面。 Parallel light emitted from the light source 11 through the first lens 13 reaches one side surface of the right-angle prism 12, the prism 13 and then reaches the upper surface. 如果光线抵达的位置不是手指16接触的直角棱镜13上表面,光线将会形成内部全反射,并从棱镜12的另一个侧面穿出,在经过第二透镜14后到达图像传感器15 ;如果光线抵达的正好是手指16接触的直角棱镜13上表面,则光线不会形成内部全反射,而是被手指13的皮肤吸收。 If not, the rectangular prism 16 on the finger 13 of the contact surface of the light arrival position, the light will form internal reflection, and out the other side of the prism 12, after passing through the second lens 14 reaches the image sensor 15; if the light arriving 13 is just the right angle prism 16 contacts the upper surface of the finger, the internal total reflection light does not form, but is absorbed by the skin of finger 13. 这样,光学指纹传感器就会捕捉到一个明暗相间的指纹图形。 Thus, the optical fingerprint sensor will capture a fingerprint pattern of light and dark.

[0004] 随着移动支付和物联网身份认证等应用的兴起,急需一种便携式电子装置,以便能够方便灵活地对指纹进行采集。 [0004] With the rise of mobile payment and authentication applications such things, and need for a portable electronic device, in order to be able to easily and flexibly to fingerprint acquisition. 然而根据以上分析可知,现有光学指纹传感器需要有多个透镜和直角棱镜配合,并且光程大,导致其厚度较大,现有光学指纹传感器的厚度通常在IOmm以上,难以运用在本身厚度已较小的便携式电子装置中。 However, according to the above analysis, the prior optical fingerprint sensor needs to have a plurality of rectangular prisms and lenses complex and large optical path, which leads to a larger thickness, the thickness of the conventional optical fingerprint sensor is typically in IOmm above, it has been difficult to apply in the thickness itself smaller portable electronic device.

[0005] 为此,亟需一种新的光学指纹采集装置,以解决现有指纹传感器厚度大的问题,同时需要一种新的便携式电子装置,以实现方便灵活地对指纹进行采集,以及需要一种光学指纹采集方法,以解决现有指纹采集方法所采集的指纹清晰度不够的问题。 [0005] To this end, a need for an optical fingerprint new means to solve the problems of the prior large thickness fingerprint sensor, and a need for a new portable electronic device, to enable easy and flexible to collect the fingerprint, and the need to An optical fingerprint collection method to solve the conventional method of fingerprint acquired fingerprint problem of insufficient clarity.

具体实施方式 Detailed ways

[0055] 正如背景技术所述,现有光学指纹传感器需要直角棱镜、第一透镜和第二透镜与一个图像传感器配合,直角棱镜、第一透镜和第二透镜增加了整个装置的厚度,并且仅由一个图像传感器采集指纹,所采集的指纹图像不够清晰。 [0055] As the background art, the conventional optical fingerprint sensor needs a rectangular prism, with the first and second lenses with an image sensor, a rectangular prism, the first and second lenses increase the thickness of the entire device, and only a fingerprint image by the sensor, the acquired fingerprint image is not clear.

[0056] 为此,本发明提供一种光学指纹采集装置,其不必使用直角棱镜以及两个透镜,因此,其厚度可以减小。 [0056] To this end, the present invention provides an optical fingerprint collection device, which is not necessary to use two rectangular prisms and lenses, and therefore, the thickness thereof can be reduced. 同时,所述光学指纹采集装置采用多个图像传感器用于指纹的采集,从而既可以进一步减小所述光学指纹采集装置的厚度,又可以提高所采集指纹的清晰度,并同时提高所述光学指纹采集装置的分辨率。 Meanwhile, the optical fingerprint collection device employs a plurality of sensors for fingerprint images, which may be further reduced thickness of the optical fingerprint collection device, and can improve the clarity of the fingerprint, and simultaneously increase the optical resolution fingerprint acquisition apparatus. [0057] 为使本发明的上述目的、特征和优点能够更为明显易懂,下面结合附图对本发明的具体实施例做详细的说明。 [0057] For the above-described objects, features and advantages of the present invention can be more fully understood by reading the following detailed description of the drawings Specific embodiments of the present invention binds.

[0058] 本发明实施例一提供一种光学指纹采集装置。 Example [0058] The present invention provides a an optical fingerprint collection device.

[0059] 请参考图2,图2是本实施例光学指纹采集装置示意图。 [0059] Please refer to FIG 2, FIG. 2 is a schematic view of an optical fingerprint acquisition apparatus embodiment. 本实施例的光学指纹采集装置中,包括光学棱镜21、光线发射模块22和多个图像传感器23。 Optical fingerprint sensor apparatus according to the present embodiment, 21 light-emitting module 22 and a plurality of image sensor comprises an optical prism 23. 多个图像传感器23均设置在电路板24上,并且每个图像传感器23都具有晶圆级光学镜头231。 A plurality of image sensors 23 are disposed on the circuit board 24, and each of the image sensor 23 has a wafer-level optical lens 231. 晶圆级光学镜头231与光学棱镜21相对。 Wafer-level optical lens 231 and the optical prism 21 opposite.

[0060] 通常的图像传感器均具有光学镜头,但是本实施例图像传感器23具有晶圆级光学镜头231,并且晶圆级光学镜头231通过晶圆级封装方法封装在图像传感器23中,不仅提高对光线的采集作用,而且能够保证图像传感器23采集的指纹信息具有一致性。 [0060] The image sensor generally has an optical lens, but the present embodiment of an image sensor 23 having a wafer-level optical lens 231, the optical lens 231 and the wafer-level package in the image sensor 23 by wafer level packaging method, not only to improve light collecting effect, but also to ensure that the image sensor 23 to capture fingerprint information consistency.

[0061] 本实施例中,光学棱镜21呈楔形。 [0061] In this embodiment, the optical prism 21 is wedge-shaped. 光学棱镜21作为导光装置,其适于手指20压盖在其表面。 The optical prism 21 as a light guide means which is adapted to the finger 20 is pressed on the surface thereof. 光学棱镜21的厚度H21可以为0.2mm〜3mm,而直角棱镜的厚度通常大于3_。 The thickness of the optical prism H21 21 may be 0.2mm~3mm, the thickness is usually greater than the rectangular prism 3_. 由此可知,由于使用了楔形的光学棱镜21,整个光学指纹采集装置的厚度可以减小。 This indicates that the use of a wedge-shaped optical prism 21, the optical thickness of the entire fingerprint device can be reduced.

[0062] 需要说明的是,在本发明的其它实施例中,也可以采用光学透镜作为导光装置。 [0062] Note that, in other embodiments of the present invention, an optical lens may be used as a light guide means.

[0063] 光线发射模块22用于提供光线,其具体可以是LED灯。 [0063] The light emitting module 22 is used to provide light, which may be a specific LED. 光线发射模块22发出的光线(未示出)通过光学棱镜21后,照射压盖在光学棱镜21表面的手指20指纹,所述指纹的反射光线(未示出)通过光学棱镜21传出,照射到图像传感器23。 Light (not shown) through the optical prism 21, the fingerprint of the finger 20 is irradiated gland surface of the optical prism 21, the reflected light of the fingerprint (not shown) of the light emitted by the module 22 emits outgoing optical prism 21 is irradiated 23 to the image sensor.

[0064] 请结合参考图3,图3是图2所示光学指纹采集装置中图像传感器23的俯视示意图。 [0064] Please refer to FIG. 3 in conjunction with FIG. 3 is an optical fingerprint sensor apparatus shown in FIG. 23 is a top schematic view of an image sensor. 本实施例中,图像传感器23有六个,六个图像传感器23呈2行X3列的阵列式排布设置在电路板24上。 In this embodiment, the image sensor 23 has six, six image sensor array 23 were arranged in two rows and disposed X3 columns on the circuit board 24.

[0065] 本实施例中,由于六个图像传感器23呈2行X 3列的阵列式排布,因此,可将对应的指纹分成2行X3列的六个部分,每个图像传感器23接收其中一个部分指纹的反射光线。 [0065] In this embodiment, since the six rows of the image sensor 23 as a 2 X 3 array arranged in rows, thus, the corresponding fingerprint may be divided into six parts X3 row 2 column, wherein each of the image sensor 23 receives a a portion of the fingerprint of the reflected light. 也就是说,所述光学指纹采集装置可以根据图像传感器23的分布方式对应地划分指纹,从而使指纹不同部分的反射光线相应地传入不同的图像传感器中,每个图像传感器接收特定部分指纹的反射光线。 That is, the optical fingerprint collection device may be divided according to the distribution mode image corresponding to the fingerprint sensor 23, so that the reflected light of different portions of the fingerprint image corresponding incoming different sensors, each image sensor receiving a specific portion of the fingerprints reflected light.

[0066] 需要说明的是,在本发明的其它实施例中,图像传感器23可以为NXM个,并且呈N行XM列的阵列式排布,其中N为大于或者等于I的自然数,M为大于或者等于I的自然数,并且N和M不同时等于I。 [0066] Note that, in other embodiments of the present invention, the image sensor 23 may be a NXM months, and is in array arranged in N rows XM columns, where N is greater than or equal to a natural number I is, M being greater than I or a natural number, and N and M are not simultaneously equal to I.

[0067] 本实施例中,光学棱镜21与图像传感器23之间的距离H22可以为Imm〜4mm,并且光学棱镜21的厚度H21和距离H22之和亦即物距(即指纹反射光线到图像传感器的距离),可知本实施例中,物距的大小范围可以为1.2mm〜7mm。 [0067] In this embodiment, the distance H22 between the optical prism 23 and the image sensor 21 may be Imm~4mm, and the thickness of the optical prism 21 H21 and H22 distance i.e. the sum of the object distance (i.e., the fingerprint reflected to the image sensor distance), it is understood the present embodiment, the object distance may be a size range 1.2mm~7mm. 晶圆级光学镜头231的焦距范围可以包括0.1臟〜3臟,具体可以为0.1臟、0.2臟、0.3臟、0.4臟、0.5臟、I臟、2臟或者3臟。 Wafer-level optical lens 231 may include a focal length range of 0.1 ~ 3 dirty dirty, particularly 0.1 may be dirty, dirty 0.2, 0.3 dirty, dirty 0.4, 0.5 dirty, the I dirty, 2 or 3 dirty dirty.

[0068] 对比现有光学指纹传感器可知,本实施例中,不需要在光线发射模块22与光学棱镜21之间设置第一透镜,也不需要在光学棱镜21与图像传感器23之间设置第二透镜,并且晶圆级光学镜头231的焦距可以设置为较小,因此,整个光学指纹采集装置的厚度进一步减小。 [0068] Comparative conventional optical fingerprint sensor seen, in this embodiment, the need to transmit a first lens disposed between the module 22 and the light in the optical prism 21, is not necessary between the optical prism 21 and the second image sensor 23 is provided lens, and the focal length of the wafer-level optical lens 231 may be set to be small, and therefore, the thickness of the entire optical fingerprint sensor apparatus is further reduced.

[0070] 请参考图4,透镜151代表图像传感器的光学镜头,物体161代表部分指纹,图像162代表物体161所成的倒立缩小的实像。 [0070] Please refer to FIG. 4, representative of the image sensor lens 151 of an optical lens, a representative portion of the fingerprint objects 161, 162 representative of the image of the object 161 into the inverted real image reduced. 物体161与透镜151之间的距离为物距uQ,图像162到透镜151之间的距离为像距V。 The distance between the object 161 and the lens 151 to the object distance uQ, the distance between the image lens 162 to the image distance of 151 V. ,而透镜151具有焦距fQ (焦点未标注,在图4中用黑点表不)。 , And the lens 151 has a focal length fQ (not labeled focus, black dots in FIG. 4 by the table does not).

[0071 ] 现有技术仅使用一个图像传感器进行图像采集。 [0071] The prior art uses only one image sensor for image acquisition. 假设物体161高度H23为6.00_,物体161最高点和最低点处的光线在经过透镜151中心时所成的角为90.0°,因此可知,物距Utl为3.00mm。 Assuming that the object 161 is 6.00_ height H23, object light 161 at the highest and lowest points in the center of the lens 151 passes through an angle of 90.0 °, and therefore understood, as the object distance Utl 3.00mm. 再假设,焦距&的大小为0.60mm,根据凸透镜成像公式有1/%=1八。 Suppose, & focal size of 0.60mm, 1 / = 1% eight imaging lens according to the formula. +1/U。 + 1 / U. ,可以求得像距V。 , Image distance can be obtained V. 的大小为0.75mm,从而可知,物距U。 Size of 0.75mm, thus found, the object distance U. 和像距V。 And image distance V. 之和为3.75mm。 Sum of 3.75mm.

[0072] 请参考图5,晶圆级光学透镜231代表图像传感器的光学镜头,物体221代表部分指纹,图像222代表物体221所成的倒立缩小的实像。 [0072] Please refer to FIG. 5, an optical lens 231 representative of the wafer level image sensor optical lens, a representative portion of the fingerprint objects 221, 222 represents the object image 221 into an inverted real image reduced. 物体221与晶圆级光学透镜231之间的距离为物距U1 (物距U1大致等于图2中厚度H21与距离H22之和),图像222到晶圆级光学透镜231之间的距离为像距V1,而晶圆级光学透镜231具有焦距(焦点未标注,在图5中用黑点表示)。 The distance between the object 221 and the optical lens 231 is a wafer-level object distance U1 (U1 object distance substantially equal to the thickness H21 2 H22 sum of the distance) to a distance between the wafer level image 222 optical lens 231, is like from V1, the wafer-level optical lens 231 has a focal length (focal not labeled, indicated by a black dot in FIG. 5).

[0073] 本实施可使用两个图像传感器进行图像采集(如图3所示,每列具有两个图像传感器23),每个图像传感器只需要感测原来物体的一半高度,即假设物体222高度H24仅为物体161高度H23的一半,为3.0Omm,并且物体221最高点和最低点处的光线在经过晶圆级光学透镜231中心时所成的角仍为90.0°,因此可知,物距U1为1.50mm。 [0073] The present embodiment may use two image sensors for image acquisition (shown in Figure 3, each column having two image sensors 23), each of the image sensor need only sense one half of the original height of the sensing object, i.e., assuming that the object height 222 H24 H23 only half the height of the object 161, is 3.0Omm, the object 221 and the light at the highest and lowest points at the center of the wafer stage 231 through the optical lens is still the angle 90.0 °, thus found, the object distance U1 It is 1.50mm. 再假设焦距的大小与焦距fo相等,即为0.60mm,根据凸透镜成像公式有,可以求得像距V1的大小为1.0Omm,从而可知,物距U1和像距V1之和为2.50mm。 Suppose the focal length is equal to the size of the focal length FO, that is 0.60mm, the imaging lens according to the formula has to be determined is the size of the image distance V1 1.0Omm, thus found, the object distance and image distance U1 V1 sum of 2.50mm.

[0074] 由于物距Utl和像距Vtl之和为3.75mm,物距U1和像距V1之和为2.50mm,可知,通过使用两个图像传感器来采集原来用一个图像传感器感测的物体,可使得相应光程减小为原来的2.50/3.75=66.7%,或者说,相应光学系统的厚度可以减小33.3%。 [0074] Since the object distance and image distance Utl Vtl sum of 3.75mm, the object distance and image distance U1 V1 sum of 2.50mm, can be seen, the original object is acquired by an image sensor sensed by using two image sensors, such that the respective optical path may be reduced to the original 2.50 / 3.75 = 66.7%, or that the thickness of the respective optical systems can be reduced 33.3%. 并且,当采用更多的图像传感器采集原来用一个图像传感器感测的物体时,相应光程减小更多,或者说相应光学系统的厚度可以减小更多。 Further, when using an image sensor to collect more of the original with a sensor for sensing an object image, the respective optical path is reduced more, or the thickness of the respective optical system can be reduced more.

[0075] 由此可知,本实施例采取多个图像传感器23采集指纹,因此,能够使整个光学指纹采集装置减小。 [0075] It can be seen, the present embodiment to take a plurality of fingerprint image sensor 23, therefore, possible to reduce the entire optical fingerprint acquisition device. 事实上,现有光学指纹传感器的厚度通常在IOmm以上,而本实施例所提供的光学指纹采集装置的厚度可以达到6_以下。 In fact, the thickness of the conventional optical fingerprint sensor is typically in IOmm above, and the thickness of the optical fingerprint collection device embodiment according to the present embodiment is provided 6_ or less can be achieved.
