Description

电容指纹芯片、失配调整方法和终端设备 技术领域
本申请涉及指纹识别领域，尤其涉及一种电容指纹芯片、失配调整方法和终端设备。
背景技术
目前，电容指纹芯片已被广泛应用于手机、笔记本电脑、平板电脑等智能终端中。电容指纹芯片即为电容式指纹识别芯片，它的工作原理是：首先，电容指纹芯片包括指纹传感器阵列，指纹传感器阵列中的每个指纹传感器包括一个感应极板和一个积分电路，当手指触摸指纹传感器时，指纹传感器跟手指的指纹会构成指纹电容，通过驱动信号可以使得指纹电容产生感应电荷，其中由于纹脊和纹谷跟感应极板距离不同，因此纹脊和纹谷对应的指纹电容的大小不同，从而导致对应的感应电荷量不同。通常将一次驱动信号使得感应电极产生感应电荷称为一次打码。指纹传感器中的积分电路可以对多次打码得到的电荷做积分处理，以得到指纹电容的电容值。其次，电容指纹芯片或终端设备中的处理器将指纹传感器阵列对应的各个电容值转换成对应的数字信号，并根据数字信号生成指纹图像，终端设备可以将该指纹图像与合法用户的指纹模板进行匹配验证，从而实现指纹识别，其中，上述匹配验证过程可以通过终端设备的处理器来实现，也可以在电容指纹芯片内部(比如芯片内部的微控制器)来实现。
通常指纹传感器阵列中不同的指纹传感器所处的位置不同，例如：有些指纹传感器处于指纹传感器阵列的中心位置，有些指纹传感器处于指纹传感器阵列的边缘位置，这种位置差异，势必造成各指纹传感器的感应电荷的差异，从而造成指纹图像效果不佳的问题，如：指纹图像存在灰度值高低不平的问题。此外，由于指纹传感器本身制造工艺的差异，电源压降等原因，这也势必造成指纹图像效果不佳的问题。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书涉及的术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
通常指纹传感器阵列中不同的指纹传感器所处的位置不同，例如：有些指纹传感器处于指纹传感器阵列的中心位置，有些指纹传感器处于指纹传感器阵列的边缘位置，这种位置差异，势必造成各指纹传感器得到的感应电荷的差异，这势必造成指纹图像效果不佳的问题，如：指纹图像存在灰度值高低不平的问题。此外，由于指纹传感器本身制造工艺的差异，电源压降等原因，这也势必造成指纹图像效果不佳的问题。
为了解决上述技术问题，本申请提供一种电容指纹芯片、失配调整方法和终端设备。图1为本申请一实施例提供的电容指纹芯片10的示意图，如图1所示，该电容指纹芯片10包括：指纹传感器阵列11、控制电路12和存储器13，其中，指纹传感器阵列11包括呈阵列式排布的多个指纹传感器(或称为指纹传感器单元)单元，比如，所述多个指纹传感器可以呈m行和n列排布，且所述指纹传感器阵列11的多个指纹传感器可以进行分组来实现指纹图像采集，其中每一分组可以称为一个指纹传感器组。在本申请中，将指纹传感器阵列中每N列指纹传感器称为一个指纹传感器组，N为大于或等于1的正整数。例如，图2为本申请一实施例提供的指纹传感器组的示意图，如图2所示，其中每5列指纹传感器构成一个指纹传感器组。
存储器13用于存储指纹传感器组对应的多个模拟参数组的使用次数；所述多个模拟参数组可以烧录至控制电路12中。或者，多个模拟参数组中的部分模拟参数组可以烧录至控制电路12中，另一部分存储在存储器13中，本申请对此不做限制。
模拟参数组是指纹传感器组在进行打码时涉及的模拟参数组；所述多个模拟参数组中的一个模拟参数组为原始模拟参数组，并且所述多个模拟参数组还包括除原始模拟参数组之外的其余模拟参数组，比如原始模拟参数组经过修正之后的修正模拟参数组。
可选地，模拟参数组包括指纹传感器组中各指纹传感器集合左侧打开的指纹传感器集合的数量和右侧打开的指纹传感器集合的数量。其中，指纹传感器集合包括至少一列指纹传感器。这种情况下，所谓原始模拟参数组是指通常电容指纹芯片在对指纹传感器组进行采集图像时，各指纹传感器集合左侧打开的指纹传感器集合的数量和右侧打开的指纹传感器集合的数量(例如：通常在对当前指纹传感器组进行图像采集时，控制电路控制当前指纹传感器 组的左侧一组指纹传感器和右侧一组指纹传感器均打开，其中当前用于图像采集的指纹传感器列或集合的左右两侧被打开但非用于图形采集的指纹传感器列或集合可以称为shadow列或shadow集合)。例如，表1为当前指纹传感器组对应的原始模拟参数组，其中当前指纹传感器组包括5个当前指纹传感器列，当前指纹传感器组左侧和右侧分别打开了一组指纹传感器，每组指纹传感器包括5列指纹传感器。需要说明的是，表1中的指纹触感器列即为上述的指纹触感器集合。
表1

在本实施例中，所述多个模拟参数组中除原始模拟参数组之外的其余模拟参数组为原始模拟参数组的修正模拟参数组。例如：表2为当前指纹传感器组对应的修正模拟参数组。需要说明的是，表2中的指纹触感器列即为上述的指纹触感器集合。
表2
Figure PCTCN2018077712-appb-000002
在本实施例中，可以遵循以下原理将原始模拟参数组修正为修正模拟参 数组：
基于当前指纹传感器组的原始模拟参数组，终端设备的处理器、电容指纹芯片或者其他设备或装置可以计算当前指纹传感器组中每个当前指纹传感器集合的影响参数，其中指纹传感器集合的影响参数与指纹传感器集合左侧打开的指纹传感器集合的数量，以及，指纹传感器集合右侧打开的指纹传感器集合的数量均呈正比；并且，指纹传感器集合的影响参数与指纹传感器集合左侧打开的各指纹传感器集合的距离，以及，指纹传感器集合右侧打开的各指纹传感器集合的距离均呈反比。
例如：当前指纹传感器集合的影响参数为当前指纹传感器集合左侧和右侧打开的指纹传感器集合对应的影响因子之和，该影响因子与当前指纹传感器集合左侧或右侧打开的指纹传感器集合的距离呈反比，即距离越近，则影响因子越大，当两个打开的指纹传感器集合与当前指纹传感器集合的距离相同，则二者对应的影响因子可以认为也相同。
如表1所示，假设与当前指纹传感器列M相邻，且为打开状态的指纹传感器列对其的第一影响因子为C1，与当前指纹传感器列M间隔一个指纹传感器列，且为打开状态的指纹传感器列对其的第二影响因子为C2，以此类推，与当前指纹传感器列M间隔八个指纹传感器列，且为打开状态的指纹传感器列对其的第九影响因子为C9，M＝1，2……5，分别计算当前指纹传感器列1至5的影响参数：
当前指纹传感器列1的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+C6+C7+C8+C9
当前指纹传感器列2的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+C7+C8
当前指纹传感器列3影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7
当前指纹传感器列4的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+C7+C8
当前指纹传感器列5的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+C6+C7+C8+C9。
图3为本申请一实施例提供的当前指纹传感器列的影响参数分布示意 图，P1至P5分别表示当前指纹传感器列1至5，如图3所示，可知当前指纹传感器列3对应的影响参数最大，其中造成各当前指纹传感器列影响参数不同的原因是各当前指纹传感器列的位置不同，而这种位置差异，势必造成各指纹传感器得到的感应电荷的差异，从而造成指纹图像效果不佳的问题，为了解决这一问题，在本申请中可以对原始模拟参数组进行修正，例如：针对当前指纹传感器列1，在其左侧增加打开一个指纹传感器组，同样，针对当前指纹传感器列2，也在其左侧增加打开一个指纹传感器组，针对当前指纹传感器列3，在其左右两侧各增加打开一个指纹传感器组，针对当前指纹传感器列4和5，分别在其右侧增加打开一个指纹传感器组，具体见表2。
如表2所示，假设与当前指纹传感器列M相邻，且为打开状态的指纹传感器列对其的第一影响因子为C1，与当前指纹传感器列M间隔一个指纹传感器列，且为打开状态的指纹传感器列对其的第二影响因子为C2，以此类推，与当前指纹传感器列M间隔11个指纹传感器列，且为打开状态的指纹传感器列对其的第九影响因子为C12，M＝1，2……5，分别计算当前指纹传感器列1至5的影响参数：
当前指纹传感器列1的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7+2*C8+2*C9+C10
当前指纹传感器列2的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7+2*C8+C9+C10+C11
当前指纹传感器列3的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7+2*C8+2*C9+2*C10+2*C11+2*C12
当前指纹传感器列4的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7+2*C8+C9+C10+C11
当前指纹传感器列5的影响参数为：
2*C1+2*C2+2*C3+2*C4+2*C5+2*C6+2*C7+2*C8+2*C9+C10
在实际应用中，可以直接将表1和表2烧录至控制电路12中，存储器13仅存储表1和表2在打码过程中的使用次数。
需要说明的是，对原始模拟参数组的修正方式不限于上述方式，例如，针对当前指纹传感器列1，在其左侧增加打开两个指纹传感器组，同样，针 对当前指纹传感器列2，也在其左侧增加打开两个指纹传感器组，针对当前指纹传感器列3，在其左右两侧各增加打开两个指纹传感器组，针对当前指纹传感器列4和5，分别在其右侧增加打开两个指纹传感器组。基于此，通过不同的修正方式可以得到多个修正模拟参数组。只要修正模拟参数组满足如下条件即可：
条件1、根据修正模拟参数组确定的指纹传感器组中任意两个指纹传感器集合的影响参数的差值，小于或等于，根据原始模拟参数组确定的任意两个指纹传感器集合的影响参数的差值。例如，基于表1所示的原始模拟参数组，当前指纹传感器列1和3的影响参数之差为C6+C7-C8-C9，基于表2所示的修正模拟参数组，当前指纹传感器列1和3的影响参数之差为C10+2*C11+2*C12，由于C6和C7均远远大于C10和C11，因此C6+C7-C8-C9大于或等于C10+2*C11+2*C12。
条件2、修正模拟参数组包括的任一个指纹传感器集合左侧打开的指纹传感器集合的数量，大于或等于，原始模拟参数组包括的任一个指纹传感器集合左侧打开的指纹传感器集合的数量，并且修正模拟参数组包括的任一个指纹传感器集合右侧打开的指纹传感器集合的数量，大于或等于，原始模拟参数组包括的任一个指纹传感器集合右侧打开的指纹传感器集合的数量。例如，基于表1所示的原始模拟参数组，当前指纹传感器列1左侧打开的指纹传感器集合的数量为5，右侧打开的指纹传感器集合的数量为10；基于表2所示的修正模拟参数组，当前指纹传感器列1左侧打开的指纹传感器集合的数量为10，右侧打开的指纹传感器集合的数量为9。
进一步地，控制电路12用于根据多个模拟参数组的使用次数，控制指纹传感器组打码，以得到多个电荷量。例如：当前指纹传感器组对应的多个模拟参数组分别如表1和表2所示内容，表1对应的使用次数为N1，表2对应的使用次数为N2，控制电路12控制指纹传感器组打码时，分别使用表1和表2的次数为N1和N2，其中指纹传感器组中的各个指纹传感器分别打码，每个指纹传感器可以获得多个电荷量。
如上所述，每个指纹传感器包括一个感应极板和一个积分电路，积分电路用于获取该指纹传感器上的多个电荷量，并对多个电荷量进行积分处理，得到该指纹传感器的电容值。
综上，在本申请中，指纹传感器组对应多个模拟参数组，其中多个模拟参数组包括原始模拟参数组和该原始模拟参数组的修正模拟参数组，也就是说，即使两个指纹传感器所处环境不同，或者其自身工艺不同，在本申请中由于控制电路用于根据所述多个模拟参数组的使用次数，控制所述指纹传感器组打码，从而可以降低指纹传感器之间的电荷量差异，进而达到较佳地图像效果。
