具体实施方式
本发明实施例提供熄屏指纹解锁方法及应用该方法的终端，以缩短熄屏指纹解锁占用时间，提高速度。
请参见图1a，上述终端可包括锁屏模块1、指纹识别模块2，此外，该终端还包括指纹传感器3。
在一个示例中，上述锁屏模块1的功能具体可由安装于终端的锁屏应用实现。
而指纹识别模块2的功能可由安装于终端中的指纹识别服务实现，在一个示例中，指纹传感器3、指纹识别模块2和后续将提及的指纹服务(FingerprintService)皆属于指纹识别服务的一部分。当需要做指纹识别时，便会透过FingerprintService调用指纹识别的功能。
当然，在另一个示例中，指纹识别服务也可不包含指纹传感器3，而包含指纹识别模块2和后续将提及的FingerprintService等。
请参见图1b，从硬件架构上，上述终端可包括总线、处理器101、存储器102、通信接口103、输入设备104和输出设备105。处理器101、存储器102、通信接口103、输入设备104和输出设备105通过总线相互连接。其中：处理器101执行存储器102中所存放的程序，以及调用其他设备，可用于实现本发明前述实施例所提供的熄屏指纹解锁方法中的各个步骤。
图1c示出了从终端的角度，熄屏指纹解锁方法的一种示例性流程。
图1d示出了终端各模块(应用)交互完成的熄屏指纹解锁方法的示例性流程。
上述熄屏指纹解锁方法可包括如下步骤：
步骤100：检测终端指纹传感器的触摸操作。
在实施中，用户触摸指纹传感器，则指纹传感器检测到被触摸。
步骤101：锁屏应用/模块对锁屏界面进行透明化处理。
透明化处理的结果是锁屏界面变成透明状，这样，一旦屏幕点亮后，锁屏界面之下的画面就会被使用者看到。
在一个示例中，可通过调节锁屏界面的透明度来实现透明化处理。透明度一般以百分比的形式出现，0％时完全透明，100％时，完全不透明。则可将透明度调节至0％，以实现令锁屏界面变成透明状。
在本发明其他实施例中，对锁屏界面进行透明化处理也可在指纹识别成功后进行。
步骤102：锁屏应用/模块进行点亮屏幕处理。
后续会对点亮屏幕处理进行介绍。
步骤103：指纹识别服务进行指纹识别处理。
需要注意的是，指纹识别处理与屏幕点亮处理是由不同的模块同步执行的。与现有的在指纹辨识成功后才开始做点亮屏幕相比，会节省时间。
步骤104：若指纹识别成功且屏幕点亮成功，解锁模块进行解锁操作。
当然，若指纹识别失败，则进行失败处理，例如提示指纹识别失败等。
可见，本发明实施例中，屏幕点亮处理和指纹识别处理是同步并行处理的。与现有的在指纹辨识成功后才开始做点亮屏幕相比，可节省时间，提高处理速度。
同时，本实施例在做屏幕点亮处理之前，还将锁屏界面透明化，这样，一旦屏幕点亮后，锁屏界面之下的画面(锁屏前的界面)就会被使用者看到。相较于现有技术，从使用者的角度看，其在按下指纹后，可更快得看到锁屏前的界面。
需要说明的是，用户看到锁屏前的界面时，终端仍是未解锁状态。但用户从看到锁屏前的界面，到将手指从指纹传感器上拿开，再到使用手指去操控其所看到的锁屏前的界面，会经历一定的时间T。在这段时间T中，终端同时在进行解锁操作。
解锁操作一般会花费100-200ms左右，而T则一般是秒级的。所以使用者并不会感觉到停顿，这样可提升使用者体验。
图2示出了上述熄屏指纹解锁方法的另一种交互式示例性流程，其至少可包括如下步骤：
步骤200：检测终端指纹传感器的触摸操作；
用户触摸指纹传感器，则指纹传感器检测到被触摸。
步骤200与步骤100相类似，在此不作赘述。
201步骤：终端提升处理器的工作频率，以加快处理器的指令周期，进而提高后续指纹识别处理的处理速度。
当然，后续的透明化处理、解锁等也会随之变快。
在一个示例中，终端可包括工作频率管理模块，由工作频率管理模块执行提升处理器的工作频率的操作。
在另一个示例中，可由终端底层完成工作频率管理模块的功能。
在其他的实施例中，指纹传感器可以检测到手指按下的中断，底层则会检测到这个中断，进而做提升处理器工作频率的处理。
在一个示例中，底层可呼叫可调节处理器频率的接口，以达到提升工作频率的目的。
以高通的芯片为例，可调节处理器频率的接口具体为perf_lockr(performance lock)接口，底层可呼叫perf_lockr接口，该接口对应perf_lock模块。perf_lock会去设置CPU在sysfs(Linux内核的一种文件***)中的节点，从而改变每一个CPU的最大/最小工作频率以及打开/关闭CPU。
或者，也可由指纹识别模块完成提升处理器的工作频率的操作。
步骤202：锁屏应用/模块对锁屏界面进行透明化处理。
透明化处理的结果是锁屏界面变成透明状，这样，一旦屏幕点亮后，锁屏界面之下的画面(即锁屏前的界面)就会被使用者看到。
步骤202与前述步骤102相类似，在此不作赘述。
步骤203：锁屏应用/模块进行屏幕点亮处理。
后续会对点亮屏幕处理进行介绍。
步骤204：指纹识别服务进行指纹识别处理。
需要注意的是，指纹识别处理与屏幕点亮处理是同时由不同的模块执行的。与现有的在指纹辨识成功后才开始做点亮屏幕相比，会节省时间。
步骤205：若指纹识别成功且屏幕点亮成功，解锁模块进行解锁操作。
当然，若指纹识别失败，则进行失败处理，例如提示指纹识别失败等。
步骤204、205，分别与前述的步骤103、104相类似，在此不作赘述。
与前述实施例最大的不同在于，本实施例增加了提升处理器的工作频率的操作(步骤201)，这样，可进一步的缩短处理时间。
图3示出了上述熄屏指纹解锁方法的又一种交互式示例性流程，其至少可包括如下步骤：
步骤300：检测终端指纹传感器的触摸操作；
用户触摸指纹传感器，则指纹传感器检测到被触摸。
步骤300与步骤100、200相类似，在此不作赘述。
步骤301：终端提升处理器的工作频率，以加快处理器的指令周期，进而提高后续指纹识别处理的处理速度。
步骤301与步骤201相类似，在此不作赘述。
步骤302：锁屏应用/模块接收触碰事件通知，对锁屏界面进行透明化处理。
在其他实施例中，指纹传感器在检测到手指触碰时，会发送触碰事件通知给锁屏应用。接收到该通知后，锁屏应用进行透明化处理。
在一个示例中，触碰事件通知可承载在回调(callback)消息中。callback消息传递路径是：指纹传感器被触碰后，会通过硬件适配层(Hardware Abstract Layer)的FingerprintDaemon发送callback给指纹服务器框架(framework FingerprintService)，framework FingerprintService再转发callback给FingerprintManager，FingerprintManager再转发callback给锁屏应用。
当然，从锁屏应用的角度看，是指纹识别模块向其发送了触碰事件通知。
透明化处理相关内容可参见前述步骤102，在此不作赘述。
步骤303：指纹识别模块(指纹识别服务)抓取图像；
步骤304：指纹识别模块(指纹识别服务)将抓取的图像与预置的指纹图像进行匹配，得到匹配结果，上述匹配结果用于表征指纹识别是否成功。
在其他实施例中，可由hal层，特别是FingerprintHal发起执行抓图和匹配。
而真正的抓图和匹配都是在TEE层(Trust Execution Environment)里 完成，得到匹配结果。因为这里的代码运行环境是可信的，所以得出的匹配结果也是可信的，再把匹配结果返回FingerprintHal，再一步步转发到FingerprintManager，从而调用的锁屏应用拿到匹配结果。
在一个示例中，可用数字0表征指纹识别成功，用数位1表征指纹识别失败，或相反；在另一个示例中，可用flag表征指纹识别是否成功，flag有两种取值，一种表征成功，一种表征失败。
在实际状况还有其他类别的讯号，所以会用两个以上的flag来表示不同的状态。例如，指纹识别的状态可包括手指接触传感器、抓取图像、识别成功/失败三种状态，则可以用三个flag来表示这三个状态。
步骤303和步骤304是前述所有实施例的指纹识别处理的细化。
步骤305：锁屏应用/模块进行屏幕点亮处理。
步骤306：若指纹识别成功且屏幕点亮成功，解锁模块进行解锁操作。
当然，若指纹识别失败，则进行失败处理，例如提示指纹识别失败等。
图4a示出了上述熄屏指纹解锁方法的又一种交互式示例性流程，其至少可包括如下步骤：
步骤400：用户触摸指纹传感器，则指纹传感器检测到被触摸。
步骤400与步骤100、200、300相类似，在此不作赘述。
步骤401：终端提升处理器的工作频率。
步骤401与步骤201、301相类似，在此不作赘述。
步骤402：锁屏应用/模块对锁屏界面进行透明化处理。
步骤402与前述的步骤101、202、302相类似，在此不作赘述。
步骤403：指纹识别模块抓取图像；
步骤404：指纹识别模块将抓取的图像与预置的指纹图像进行匹配，得到匹配结果，上述匹配结果用于表征指纹识别是否成功。
步骤403和404分别与步骤303和304相类似，在此不作赘述。
步骤405：锁屏应用/模块通知底层进行窗口绘图。
在其他实施例中，是由锁屏应用经由窗口管理器(Windowmanager)通知底层绘制窗口。具体如何绘制窗口请参见现有的绘制窗口方式，在此不作赘述。
步骤406：若窗口绘图完成且指纹识别成功，窗口管理器执行屏幕照明光源的点亮操作。
在一个示例中，是由锁屏应用/模块开启了点亮屏幕的程序，该程序会根据窗口绘制及指纹辨识是否完成来决定是否点亮背光，最后的判断点在窗口管理器。
在其他实施例中，在熄屏解锁的过程中，点亮的命令是由锁屏应用发出至电源管理器(PowerManager)的wakeup接口，点亮流程中会经过窗口管理器检查window绘制结果/状态以及指纹辨识结果/状态，若窗口绘图完成且指纹识别成功，最后通知电源管理器点亮照明光源。
在一个示例中，窗口管理器会去获取指纹识别的状态。指纹识别的状态可包括手指接触传感器、抓取图像、识别成功/失败三种状态。在识别成功状态并且窗口绘图完成时，会通知电源管理器点亮屏幕照明光源。
在一个示例中，屏幕照明光源可为发光二极管(LED，Light Emitting Diode)背光源。当然，屏幕照明光源也可为有机发光二极管(OLED，Organic Light Emitting Diode)光源或其他光源。
步骤407：若指纹识别成功且屏幕照明光源点亮成功，解锁模块进行解锁操作。
当然，若指纹识别失败，则进行失败处理，例如提示指纹识别失败等。
需要说明的是，指纹识别失败后，就不会点亮点亮屏幕照明光源.点亮的流程会被中断。
图4b示出了使用者将手指放在指纹传感器上后，终端中的各模块(器 件)分两条支路(路径)最终实现点亮的处理过程。
为加以区别，以数字和英文分别表示两条支路(路径)。
路径1：
S1-S3：指纹传感器被触碰后，通过FingerprintHal、FingerprintService等转发callback至锁屏应用。
S4：锁屏应用发送点亮命令给电源管理器；
详见步骤406。
S5：电源管理器发送点亮命令给窗口管理器；
S6：窗口管理器通知SurfaceFinger绘制窗口；
S7：窗口管理器从SurfaceFinger获取绘制结果/状态。
窗口管理器可主动从SurfaceFinger处获取绘制结果/状态，也可由SurfaceFinger向窗口管理器发送绘制结果/状态。
S8：窗口管理器在窗口绘图完成且指纹识别成功时，通知电源管理器点亮照明光源。
路径2：
a：指纹传感器检测到手指按下的中断；
b：FingerprintHal发起执行抓图和匹配。
真正的抓图和匹配都是在TEE层里完成，并得到匹配结果。因为这里的代码运行环境是可信的，所以得出的匹配结果也是可信的，再把匹配结果返回FingerprintHal。
c-e:匹配结果(指纹辨识结果/状态)通过FingerprintHal、FingerprintService、锁屏应用等转发至窗口管理器。
窗口管理器在获取了绘制结果/状态(表征完成)和匹配结果(表征辨识成功)后，会执行上述步骤S8。
Surfaceflinger是一个类，同时又是线程，该线程通过循环，不断计算 并刷新当前屏幕需要的显示内容。Surfaceflinger线程属于SystemServer进程，也就是在SystemServer进程中启动了Surfaceflinger线程。Surfaceflinger中保存着各种layer，其主要工作就是负责各种layer的融合，因此可看做一个用于维护各种layer的线程。启动Android线程需要提供两个接口，一是readyToRun()，该函数定义了线程循环前需要初始化的内容；二是threadLoop()，每个线程都必须实现，该函数定义了线程执行的内容，如果该函数返回真(true)，线程会继续调用threadLoop()，如果返回假(false)，线程将退出。
本发明还要求保护上述所有实施例中的终端。
终端的一种示例性结构可参见图1a，其可包括：
锁屏模块1，配置为进行屏幕点亮处理，若指纹识别成功且屏幕点亮成功，进行解锁操作；

需要注意的是，指纹识别处理与屏幕点亮处理同时并行执行。
在本发明其他实施例中，还可包括：工作频率管理模块，配置为在指纹传感器3检测到被触碰时，提升终端的处理器的工作频率。
在本发明其他实施例中，锁屏模块1还可配置为：在进行点亮屏幕处理之前，对锁屏界面进行透明化处理；或者，在指纹识别成功后，对锁屏界面进行透明化处理。
相关内容请参见方法部分的记载，在此不作赘述。
在本发明其他实施例中，上述所有实施例中的锁屏模块还可配置为：
接收指纹识别模块发送的触碰事件通知，所述触碰事件通知用于表征所述指纹传感器检测到被触碰。具体细节请参见前述的步骤302，在此不作赘述。
上述透明化处理及屏幕点亮处理是在接收到该触碰事件通知后被触发执行的。
锁屏模块1可执行图1c和图1d所示的步骤101-102、104，图2所示的步骤202、203、205，图3所示的步骤305、306，图4a所示的步骤402，405-407。

则相应的，在进行屏幕点亮处理方面，锁屏模块1具体配置为：通知绘图模块502进行窗口绘图；通知屏幕照明光源点亮模块502执行屏幕照明光源的点亮操作。
在其他实施例中，锁屏模块1可向屏幕照明光源点亮模块502发送点亮命令。屏幕照明光源点亮模块502接收到点亮命令后，执行屏幕照明光源的点亮操作。
在一个示例中，在执行屏幕照明光源的点亮操作的方面，屏幕照明光源点亮模块502可具体配置为：在窗口绘图完成且指纹识别成功时，点亮屏幕照明光源。
在其他实施例中，屏幕照明光源点亮模块502可配置为：获取窗口的绘制结果/状态以及指纹辨识结果/状态；若绘制结果/状态表征窗口绘图完成，并且指纹辨识结果/状态表征指纹识别成功，则点亮屏幕照明光源。
在一个示例中，绘制结果/状态中的数值可为0或1，可用数字0表征窗口绘图未完成，用数位1表征窗口绘图未完成，或相反；在另一个示例中，可用flag表征窗口绘图是否完成，flag有两种取值，一种表征完成，一种表征未完成。
同理，在一个示例中，指纹辨识结果/状态中的数值可为0或1，可用数字0表征指纹识别成功，用数位1表征指纹识别失败，或相反；在另一个示例中，可用flag表征指纹识别是否成功，flag有两种取值，一种表征成功，一种表征失败。在实际状况还有其他类别的讯号，所以会用两个以上的flag来表示不同的状态。例如，指纹识别的状态可包括手指接触传感器、抓取图像、识别成功/失败三种状态，则可以用三个flag来表示这三个状态。
屏幕照明光源点亮模块502的功能可由前述步骤406中提及的wakeup接口、窗口管理器和Pwermanager等交互实现。
