输入方法及电子设备
本申请要求于2019年07月25日提交中国专利局、申请号为201910677040.2、申请名称为“输入方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子设备技术领域，尤其涉及一种输入方法及电子设备。
背景技术
随着触摸屏的普及，人们在使用电子产品时的输入方式已由物理按键输入转变为触摸屏输入。触摸屏输入是通过触摸屏接收用户在屏幕上的操作，以使电子设备做出与该操作对应的响应。用户最常用的操作通常包括短按(即点击)、长按及滑动等。
但是由于不同的用户对于短按和长按的时长理解和操作不一致，经常会造成部分用户想短按的时候变成了长按，从而使电子设备错误响应。比如，用户想要短按拍一张照片时，由于输入被识别成长按而导致连拍多张照片。再比如，用户想要短按查看单张图片时，由于输入被识别成长按而导致进行图片选择等。可以看出，由于电子设备无法准确识别用户输入的操作，会导致电子设备做出错误响应，从而导致用户输入效率低。

可以知道，图5中的C示出的选择结果仅为示例性说明，在具体实现中还可以有其他的选择结果，本申请实施例对此不作限定。
可以知道，以上列举的三个使用场景仅为示例性说明，在具体实现中，本申请实施例还可以应用于其他场景，例如对文件列表中某个文件的短按操作或长按操作等，本申请实施例对此不作限定。
本申请以下实施例将用于区分一个按压操作是长按操作还是短按操作的时间临界值简称为临界值，按压时长大于或等于该临界值的按压操作为长按操作，按压时长小于该临界值的按压操作为短按操作(即点击操作)。由于不同用户的操作习惯不同，适用于不同用户的临界值也不同。
接下来分别介绍两种临界值的计算方式。
方式一：根据用户年龄和用户按压控件的压力值(以下简称触控压力值)计算适用于该用户的临界值。
具体地，根据用户年龄和触控压力值计算在基准值基础上的调节时长。临界值与用户年龄和触控压力值的关系式可以如下：
Time＝basetime+θ(α*F(age)+β*F(pressure))   (1)
式(1)中，Time为临界值，basetime为基准值，F(age)为年龄对应的调节时长、F(pressure)为触控压力值对应的调节时长，0<θ<1、0<α<1、0<β<1。可能的，基准值可以但不限于是400毫秒(ms)。可能地，θ的值可以但不限于是0.08，α的值可以但不限于是0.5，β的值可 以但不限于是0.5。
其中，表1示例性示出了用户年龄与调节时长的关系。
表1 用户年龄age与调节时长F(age)的关系表
age(岁) F(age)
0＜age≤60 0ms
age＞60 100ms
可以看出，表1中的第一列为年龄分类，第二列为调节时长。其中，年龄分类可以包括：0＜age≤60及age＞60。其中，0＜age≤60对应的调节时长F(age)为0ms；age＞60对应的调节时长F(age)为100ms。
可以知道，上述年龄分类仅为示例性说明，在具体实现中还可以有其他的年龄分类，本申请实施例对此不作限定。
可以知道，上述年龄分类对应的调节时长F(age)的值仅为示例性说明，在具体实现中还可以对应其他的调节时长F(age)的值，调节时长F(age)的值也不限于是非负数，在具体实现中还可以是负数，本申请实施例对此均不作限定。
表2示例性示出了触控压力值pressure与调节时长F(pressure)的关系。
表2 触控压力值pressure与调节时长F(pressure)的关系表
pressure(牛) F(pressure)
0＜pressure≤0.7 0ms
0.7＜pressure≤0.9 50ms
pressure＞0.9 150ms
可以看出，表2中的第一列为触控压力值分类，第二列为调节时长。其中，触控压力值分类可以包括：0＜pressure≤0.7、0.7＜pressure≤0.9及pressure＞0.9。其中，0＜pressure≤0.7对应的调节时长F(pressure)为0ms；0.7＜pressure≤0.9对应的调节时长F(pressure)为50ms；pressure＞0.9对应的调节时长F(pressure)为150ms。
示例性地，若用户年龄大于60岁，则查询表1可知调节时长F(age)＝100ms，若用户的触控压力值pressure＞0.9，则查询表2可知调节时长F(pressure)＝150ms。假设式(1)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(1)可以计算出临界值Time＝400+0.08×(0.5×100+0.5×150)＝410ms。
示例性地，若用户年龄小于60岁，则查询表1可知调节时长F(age)＝0ms，若用户的触控压力值0.7＜pressure≤0.9，则查询表2可知调节时长F(pressure)＝50ms。假设式(1)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(1)可以计算出临界值 Time＝400+0.08×(0.5×0+0.5×50)＝402ms。
可以知道，上述触控压力值分类仅为示例性说明，在具体实现中还可以有其他的触控压力值分类，本申请实施例对此不作限定。
可以知道，上述触控压力值分类对应的调节时长F(pressure)的值仅为示例性说明，在具体实现中还可以对应其他的调节时长F(pressure)的值，调节时长F(pressure)的值也不限于是非负数，在具体实现中还可以是负数，本申请实施例对此均不作限定。
不限于在基准值的基础上计算调节时长以获得临界值，在具体实现中还可以直接根据用户年龄和触控压力值确定临界值，本申请实施例对此不作限定。
接下来介绍如何确定用户的年龄分类。
具体地，电子设备100可以根据人脸解锁时摄像头捕捉的图像进行年龄分类。具体可以利用卷积神经网络对人脸进行年龄估计，将人脸图像输入到卷积神经网络系统中计算该人脸图像属于每一种年龄分类的概率，确定概率最大的年龄分类为该人脸图像的年龄分类。上述卷积神经网络可以是年龄分类模型。
接下来介绍年龄分类模型的训练过程。年龄分类模型的训练过程至少可以包括以下几个步骤：
步骤一：确定样本集。样本集可以包括多张人脸图像以及该人脸图像对应的年龄分类。
步骤二：设置各个年龄分类对应的标准人脸图像。
步骤三：比对样本集中人脸图像的人脸特征关键点和标准人脸图像的人脸特征关键点，对样本集中的人脸图像进行关键点对齐和调整，再对调整后的样本集中的人脸图像进行轮廓提取得到人脸轮廓图，并将该人脸轮廓图进行归一化处理并输入卷积神经网络系统进行分类模型的训练。
具体地，上述人脸特征关键点包括但不限于是：眼睛轮廓、嘴部轮廓、眉毛轮廓、脸部轮廓、额头轮廓等。可能地，人脸图像可以但不限于包括88个人脸特征关键点。
具体地，上述关键点对齐和调整用于将该人脸图像与各个年龄分类对应的标准人脸进行比对，确定与该人脸图像最接近的年龄分类对应的标准人脸，再利用仿射变换对人脸图像进行旋转和平移，将人脸图像与标准人脸图像中人脸的角度和位置调整为一致，避免因为人脸图像中人脸的角度或人脸在图像中的位置引起的误差。
具体地，轮廓提取具体可以是对人脸各个部位(如眉毛、眼睛、嘴巴等)的轮廓线进行拟合。具体可对上述调整后的人脸图像进行小波变换，过滤高频分量并去噪，得到低频分量的频域图像，即人脸轮廓图像。
具体地，归一化处理可以用于将上述人脸轮廓图像进行归一化处理，将各个不同大小的人脸轮廓图处理成同样大小的人脸轮廓图，避免不同大小的人脸引起的误差。
模型训练完成后，可依次将样本集中的人脸图像再次输入到该年龄分类模型中，对比人脸分类模型输出的结果与该人脸图像的年龄分类是否一致。若不一致，收集该人脸图像作为样本图像，再次执行上述步骤一至步骤三，进行年龄分类模型的校准，直至最终输出结果的准确率超过预设阈值，如90％，得到最终的年龄分类模型。
本申请实施例中提供的年龄分类模型的网络结构顺序为输入层、K个小组层、全连接层及softmax层，其中，K大于或者等于1。
上述输入层可以用于接收输入的待识别的人脸图像，输入的人脸图像为YUV数据，输入层可以将输入的YUV数据转换成RGB数据。
上述小组层可以用于将输入层输出的RGB数据进行卷积和归一化处理。小组层可以包括卷积层、激活层、归一化层。卷积层、激活层、归一化层中每个层的核大小以及输出大小都可任意调节，且每个层都有一个输入且产生一个输出，每一层的输出作为下一层的输入。
上述全连接层可以用于对人脸图像轮廓线的拟合。
上述softmax层用于输出年龄分类的输出结果。输出结果具体可以是每一种年龄分类的概率。每一种年龄分类的概率均属于[0,1]，且各个年龄分类的概率和为1。确定概率最大的年龄分类为输入的人脸图像的年龄分类。
例如，本申请实施例中可以根据年龄分为两类：0＜age≤60，age＞60。若将某人脸图像输入到上述年龄分类模型中，softmax层输出的结果为：0＜age≤60的概率为80％，age＞60的概率为20％，则确定该人脸图像最终的年龄分类为0＜age≤60。
不限于上述列举的年龄分类，在具体实现中还可以有其他的年龄分类，如可以分为：0＜age≤2、2＜age≤6、6＜age≤14、14＜age≤35、35＜age≤60及age＞60等，本申请实施例对年龄的具体分类不做限定。
不限于输出年龄范围，在具体实现中还可以用文字替代年龄范围，例如将年龄范围2＜age≤6替换成儿童，将年龄范围14＜age≤35替换成青年等，本申请实施例对输出结果的具体表现形式不作限定。
不限于人脸解锁时摄像头捕捉的图像，在具体的实现中还可以根据用户采用前置摄像头自拍时摄像头捕捉的图像进行年龄识别，本申请实施例对此不作限定。
可能地，电子设备100的内部存储器121中可以保存机主的人脸图像，用于人脸解锁。电子设备100可以直接获取内部存储器121中保存的人脸图像并进行年龄识别。
接下来介绍如何确定触控压力值。
具体地，电子设备100可以通过压力传感器180A检测触控压力值。
具体地，可以将触控压力值分为几个范围，例如本申请实施例中可以将触控压力值分为三个范围：0＜pressure≤0.7、0.7＜pressure≤0.9及pressure＞0.9等。
本申请实施例中用于计算临界值的触控压力值可以是电子设备100采集用户在一段时间内的触控压力值得出的结果，也可以是用户单次点击控件时的触控压力值。
可能地，若电子设备100采集用户在一段时间内的触控压力值，则可将用户在一段时间内触控压力值所在的频率最高的范围确定为用户触控压力值所属的范围。根据表2可以确定该触控压力值范围对应的调节时长，从而根据调节时长计算临界值。采用该方式计算的触控压力值可以符合用户长期的使用习惯，避免由于单次操作失误导致计算的触控压力值不准确。
例如，电子设备100可以检测用户在一天内对任一控件输入触控操作时的压力值。若用户在一天内输入100次触控操作，这100次触控操作中有60次触控操作的触控压力值的范围为0.7＜pressure≤0.9，25次触控操作的触控压力值的范围为0＜pressure≤0.7，15次 触控操作的触控压力值的范围为pressure＞0.9，则电子设备100可以确定用户的触控压力值的范围为0.7＜pressure≤0.9。根据表2可以进一步确定该用户的触控压力值对应的调节时长F(pressure)为50ms。
若触控压力值为用户单次点击控件时的触控压力值，则电子设备100可以在用户输入触控操作时，实时计算适用于当前触控操作的临界值，并根据临界值的计算结果对用户输入的触控操作做出响应。采用该方式可以对每次触控操作做出准确的响应，不因使用者的变化而影响电子设备对触控操作的响应的准确性。
可能地，触控压力值可以是用户在一段时间内按压任意控件平均压力值。
具体地，电子设备100可以采集用户在一段时间内按压任意控件的压力值。该一段时间例如但不限于是一天。电子设备100可以记录出用户在一段时间内按压控件的次数，以及按压每个控件时的压力值，计算出按压所有控件时的压力值的总和除以按压次数的值，即为该用户在一段时间内按压任意控件的平均压力值。该平均压力值即为触控压力值。
不限于与用户年龄及触控压力值有关，在具体实现中临界值还可以只与用户年龄有关，或者只与触控压力值有关，本申请实施例对此不作限定。
方式二：根据电子设备100的字体大小和用户按压控件的压力值(即触控压力值)计算适用于该用户的临界值。
具体地，如何确定触控压力值可以参考方式一中的相关部分，此处不赘述。
具体地，为了便于用户更清晰的查看电子设备100显示的内容，年龄较大的用户通常会将电子设备100的字体设置成较大的字体。因此电子设备100的字体大小可以在一定程度上反映用户的年龄。可以知道，电子设备100的字体大小可以由用户设置，字体大小通常可以包括以下几种类型：特大、超大、大、标准及小。字体类型为特大的字占显示屏的面积最大，字体类型为超大的字占显示屏的面积次之，字体类型为小的字占显示屏的面积最小。
具体地，临界值与电子设备100的字体大小和用户按压控件的压力值的关系式可以如下：
Time＝basetime+θ(α*F(font)+β*F(pressure))   (2)
式(2)中，Time为临界值，basetime为基准值，F(font)为字体对应的调节时长、F(pressure)为触控压力值对应的调节时长，0<θ<1、0<α<1、0<β<1。可能的，基准值可以但不限于是400毫秒(ms)。可能地，θ的值可以但不限于是0.08，α的值可以但不限于是0.5，β的值可以但不限于是0.5。
其中，表3示例性示出了字体大小与调节时长的关系。
表3 字体大小font与调节时长F(font)的关系表
font F(font)
特大 500ms
超大 250ms
大 0ms
标准 0ms
小 0ms
可以看出，表3中的第一列为字体大小分类，第二列为调节时长。其中，字体大小分类可以包括：特大、超大、大、标准、小。其中，字体类型为特大时对应的调节时长F(font)为500ms；字体类型为超大时对应的调节时长F(font)为250ms；字体类型为大、标准或小时对应的调节时长F(font)为0ms。
示例性地，若字体大小为超大，则查询表3可知调节时长F(font)＝250ms，若用户的触控压力值0.7＜pressure≤0.9，则查询表2可知调节时长F(pressure)＝50ms。假设式(2)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(2)可以计算出临界值Time＝400+0.08×(0.5×250+0.5×50)＝412ms。
示例性地，若字体大小为标准，则查询表3可知调节时长F(age)＝0ms，若用户的触控压力值0＜pressure≤0.7，则查询表2可知调节时长F(pressure)＝0ms。假设式(2)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(2)可以计算出临界值Time＝400+0.08×(0.5×0+0.5×0)＝400ms。
示例性地，若字体大小为特大，则查询表3可知调节时长F(age)＝500ms，若用户的触控压力值pressure＞0.9，则查询表2可知调节时长F(pressure)＝150ms。假设式(2)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(2)可以计算出临界值Time＝400+0.08×(0.5×500+0.5×150)＝426ms。
可以知道，上述字体大小分类仅为示例性说明，在具体实现中还可以包括更多的或更少的字体类型，本申请实施例对此不作限定。
可以知道，上述字体大小分类对应的调节时长F(font)的值仅为示例性说明，在具体实现中还可以对应其他的调节时长F(font)的值，调节时长F(font)的值也不限于是非负数，在具体实现中还可以是负数，本申请实施例对此均不作限定。
不限于与字体大小及触控压力值有关，在具体实现中临界值还可以只与字体大小有关，或者只与触控压力值有关，本申请实施例对此不作限定。
不限于上述列举的两种方式，在具体实现中，临界值还可以由用户年龄及字体大小共同决定。
不限于上述列举的两种方式，在具体实现中临界值还可以由用户年龄、字体大小及触 控压力值三者共同决定，本申请实施例对此不作限定。
也即是说，临界值可以由用户年龄、字体大小及触控压力值中的至少一项决定。
基于上述列举的场景二，接下来介绍本申请实施例提供的拍照方法。该方法可以应用于图1示出的电子设备100，电子设备100上可安装相机应用。
图6示例性示出了本申请实施例提供的一种拍照方法的流程示意图。如图6所示，拍照方法至少可以包括以下几个步骤：
S101：接收用户作用于相机应用的拍摄控件的按压操作。
具体地，电子设备100可以通过触摸传感器180K检测作用于相机应用的拍摄控件301的按压操作。其中，按压操作可以根据按压时长分为长按操作和短按操作。
S102：根据用户的年龄及按压操作的按压时长共同确定按压操作对应的目标事件；其中，目标事件为拍摄一张照片或连续拍摄多张照片。
具体地，本申请实施例可以针对不同的用户的年龄可以设置不同的临界值。该临界值可以用来区分一个按压操作是长按操作还是短按操作。按压时长小于该临界值的按压操作为短按操作，目标事件为拍摄一张照片。按压时长大于或等于该临界值的按压操作为长按操作，目标事件为连续拍摄多张照片。
其中，连续拍摄照片的频率可以但不限于是每秒10张或每秒5张，具体的拍摄频率可由用户设置，或由厂商设置的默认拍摄频率。
S103：执行目标事件。
可能地，上述临界值可以根据用户年龄和触控压力值确定。触控压力值可以是用户在一段时间内按压任意控件的平均压力值。
可能地，上述临界值可以根据用户年龄和触控压力值所属的范围确定。具体可以将用户在一段时间内按压任意控件的压力值分为几个范围，触控压力值所属的范围为该用户在这一段时间内按压任意控件的压力值所属的频率最高的范围。
确定触控压力值的具体过程可见前述实施例中关于如何确定触控压力值部分的描述，此处不赘述。
关于用户年龄，具体可以通过两种方式来确定：
方式一：获取用户的人脸图像，根据用户的人脸图像直接确定用户年龄。
可能地，可以在电子设备进行人脸解锁时获取人脸图像。
可能地，可以从内部存储器121中获取保存的机主的人脸图像，该人脸图像用于人脸解锁。
具体地，获取人脸图像后，将人脸图像输入到卷积神经网络中，输出该人脸图像对应的年龄或年龄分类。该卷积神经网络可以是年龄分类模型，该模型可以由多个已知年龄分类的人脸图像训练而成。具体过程可见前述实施例中关于如何确定用户的年龄分类部分的描述，此处不赘述。
方式二：通过电子设备的字体大小间接确定用户年龄。
具体地，电子设备100的字体大小可在一定程度上反映用户的年龄。本申请实施例中提到的根据电子设备的字体大小间接确定用户年龄可以是指根据电子设备的字体大小确定字体大小对应的调节时长，而该调节时长是依据字体大小反映的用户年龄设置的。通常情 况下，字体越大可以表明用户的年龄越大，用户在按压控件时所需的反应时间也越长，因此对应的调节时长就越长。
临界值的具体计算方式可以参考前述实施例中关于介绍临界值的计算方式一和方式二部分的相关描述，此处不赘述。
本申请实施例提供的输入方法可以根据用户的年龄和按压操作的按压时长确定用户输入的按压操作是长按操作或者短按操作，为不同年龄的用户设置不同的反应时间。所有用户都可以按照自己对时长定义的理解输入短按操作或长按操作，从而使相机拍摄一张照片或者连续拍摄多张照片，提升用户拍摄的效率。
依然基于上述列举的场景二，接下来介绍本申请实施例提供的另外一种拍照方法。该方法中，两个年龄不同的用户分别对相机应用的拍摄控件输入同样的按压时长的按压操作，可以使电子设备做出不同的响应。
图7示例性示出了本申请实施例提供的另外一种拍照方法的流程示意图。如图7所示，拍照方法至少可以包括以下几个步骤：
S201：接收第一用户作用于相机应用的拍摄控件的第一按压操作。
具体地，电子设备100可以通过触摸传感器180K检测作用于相机应用的拍摄控件301的第一按压操作。
S202：响应于第一按压操作，拍摄一张照片。
具体地，第一按压操作为短按操作，电子设备100可拍摄一张照片。
S203：接收第二用户作用于相机应用的拍摄控件的第二按压操作。
具体地，电子设备100可以通过触摸传感器180K检测作用于相机应用的拍摄控件301的第二按压操作。
S204：响应于第二按压操作，连续拍摄多张照片。
具体地，第二按压操作为长按操作，电子设备100可连续拍摄多张照片。
其中，第一用户的年龄大于第二用户的年龄，第一按压操作和第二按压操作的按压时长相同。可以看出，在本申请实施例中，两个年龄不同的用户输入相同按压时长的按压操作后，电子设备100可以做出不同的响应。年龄较大的用户输入按压操作后，电子设备可拍摄一张照片。年龄较小的用户输入同样时长的按压操作后，电子设备可连续拍摄多张照片。
具体地，本申请实施例可以针对不同的用户的年龄可以设置不同的临界值。第一用户对应的临界值可称为第一临界值，第二用户对应的临界值可称为第二临界值。第一临界值可以用来区分第一按压操作是长按操作还是短按操作。第二临界值可以用来区分第二按压操作是长按操作还是短按操作。
可知，电子设备100可判断出第一按压操作的按压时长小于第一临界值，确定第一按压操作对应的第一目标事件为拍摄一张照片，并执行该第一目标事件。电子设备100可判断出第二按压时长大于或等于第二临界值，确定第二按压操作对应的第二目标事件为连续拍摄多张照片，并执行该第二目标事件。
其中，连续拍摄照片的频率可以但不限于是每秒10张或每秒5张，具体的拍摄频率可由用户设置，或由厂商设置的默认拍摄频率。
可能地，上述第一临界值(或第二临界值)可以根据第一用户(或第二用户)年龄和第一触控压力值(或第二触控压力值)确定。第一触控压力值(或第二触控压力值)可以是第一用户(或第二用户)在一段时间内按压任意控件的平均压力值。
可能地，上述第一临界值(或第二临界值)可以根据第一用户(或第二用户)年龄和第一触控压力值(或第二触控压力值)所属的范围确定。具体可以将第一用户(或第二用户)在一段时间内按压任意控件的压力值分为几个范围，第一触控压力值(或第二触控压力值)所属的范围为第一用户(或第二用户)在这一段时间内按压任意控件的压力值所属的频率最高的范围。
确定第一触控压力值(或第二触控压力值)的具体过程可见前述实施例中关于如何确定触控压力值部分的描述，此处不赘述。
关于第一用户(或第二用户)年龄，具体可以通过两种方式来确定：
方式一：获取第一用户(或第二用户)的人脸图像，根据第一用户(或第二用户)的人脸图像直接确定第一用户(或第二用户)年龄。
可能地，可以在电子设备100进行人脸解锁时获取人脸图像。
可能地，可以从内部存储器121中获取保存的机主的人脸图像，该人脸图像用于人脸解锁。
具体地，获取人脸图像后，将人脸图像输入到卷积神经网络中，输出该人脸图像对应的年龄或年龄分类。该卷积神经网络可以是年龄分类模型，该模型可以由多个已知年龄分类的人脸图像训练而成。具体过程可见前述实施例中关于如何确定用户的年龄分类部分的描述，此处不赘述。
方式二：通过电子设备100的字体大小间接确定第一用户(或第二用户)年龄。
具体地，电子设备100的字体大小可在一定程度上反映用户的年龄。本申请实施例中提到的根据电子设备的字体大小间接确定用户年龄可以是指根据电子设备的字体大小确定字体大小对应的调节时长，而该调节时长是依据字体大小反映的用户年龄设置的。通常情况下，字体越大可以表明用户的年龄越大，用户在按压控件时所需的反应时间也越长，因此对应的调节时长就越长。
第一临界值(或第二临界值)的具体计算方式可以参考前述实施例中关于介绍临界值的计算方式一和方式二部分的相关描述，此处不赘述。
可知，电子设备100的字体大小可由用户设置。第一用户使用电子设备100时，电子设备100的字体大小为第一字体大小；第二用户使用电子设备100时，电子设备100的字体大小为第二字体大小。其中，第一字体大小大于第二字体大小。字体大小越大的字体占显示屏的面积越大，字体大小越小的字体占显示屏的面积越小。例如，第一字体大小可以是特大，第二字体大小可以是标准。
本申请实施例中两个年龄不同的用户输入同样按压时长的按压操作，电子设备可以做出不同的响应。根据用户的年龄确定用户输入的按压操作是长按操作或者短按操作，为不同年龄的用户设置不同的反应时间。所有用户都可以按照自己对时长定义的理解输入短按操作或长按操作，从而使相机拍摄一张照片或者连续拍摄多张照片，提升用户拍摄的效率。
接下来介绍一个本申请实施例提供的一种具体的拍照方法，以用户对拍摄控件输入按压操作为例进行说明。
场景设定：
假设电子设备在接收用户对拍摄控件输入按压操作之前，已根据用户的年龄和触控压力值确定了临界值。假设电子设备根据人脸解锁时摄像头捕捉到的图像进行年龄分类，识别出用户的年龄大于60岁，则查询表1可知调节时长F(age)＝100ms。假设电子设备采集用户在一段时间内触控压力值所在的频率最高的范围为0.7＜pressure≤0.9，则查询表2可知调节时长F(pressure)＝50ms。假设式(1)中的基准值basetime＝400ms，θ＝0.08，α＝0.5，β＝0.5，则根据式(1)可以计算出临界值Time＝400+0.08×(0.5×100+0.5×50)＝406ms。
图8示例性示出了本申请实施例提供的一种具体的输入方法的流程示意图。如图8所示，输入方法可以包括以下几个步骤：
S301：触摸传感器180K检测作用于拍摄控件301的按压操作。
具体地，电子设备检测到作用于拍摄控件301的按压操作后，可以屏蔽对系统原生长按事件的监听，系统原来设定的长按时长例如可以是400ms(即按压操作的按压时长超过或等于400ms即为长按操作)。且电子设备100可以重新设置长按时长，将该长按时长修改为根据用户年龄和/或触控压力值计算得到的临界值406ms。具体可以通过内部重写触发触摸事件onTouchEvent方法重新设置系统原来设定的长按时长。
S302：响应于该按压操作，计时器196开始计时。
S303：处理器110判断计时器196的计时结果是否大于或等于临界值。若是，执行S304，若否，执行S307。
具体地，临界值可以是处理器110预先根据用户年龄和触控压力值计算得到的值。具体示例可见前述场景设定。上述计算临界值的过程可以是处理器110执行的。
S304：摄像头193按照预设频率拍摄照片。
具体地，预设频率例如可以是每秒10张或每秒5张，具体拍摄频率可以由用户设置，或由电子设备厂商设置默认拍摄频率。
S305：触摸传感器180K判断按压操作是否结束。若是，执行S306，若否，执行S304。
S306：计时器196结束计时，摄像头193停止拍摄照片。
具体地，按压操作结束后，电子设备100还可以重置拍摄控件301的状态，直到再次检测到作用于该控件的按压操作。
S307：触摸传感器180K检测到按压操作结束，摄像头193拍摄一张照片。
可能地，电子设备100检测到作用于拍摄控件301的按压操作的同时，还可以检测到滑动操作，在检测到该滑动操作超出该控件的区域时，计时器196也可以停止计时，电子设备100可以根据计时器196的计时结果做出响应。
本申请实施例中，用户在对拍摄控件输入按压操作时，电子设备可以根据用户的年龄及触控压力值计算出适用于该用户的临界值，根据用户输入的按压操作的时长与临界值的关系，准确判断用户意图，使电子设备做出正确的响应，避免由于用户对操作时长的理解不准确或用户的操作习惯导致电子设备错误响应，提升用户的输入效率，提升用户体验。
基于以上列举的三个应用场景，接下来介绍本申请实施例提供的输入方法。
图9示出了本申请实施例提供的输入方法的流程示意图。如图9所示，输入方法至少可以包括以下几个步骤：
S401：检测作用于第一控件的按压操作。
具体地，第一控件可以是图3实施例中的相机图标202，第一控件还可以是图4实施例中的拍摄控件301，第一控件还可以是图5实施例中的某张照片的缩略图。不限于上述列举的控件，在具体实现中第一控件还可以是其他的控件，本申请实施例对此不作限定。
S402：根据该按压操作的时长与临界值的关系确定该按压操作的类型。
其中，按压操作的类型包括短按操作和长按操作。
可能地，上述临界值可以由用户年龄及触控压力值决定。其中，触控压力值为该用户在一段时间内按压任意控件的压力平均值，具体可参考前述实施例中关于如何确定触控压力值部分的相关描述，此处不再赘述。
可能地，上述压力值可以由用户年龄及触控压力值所属的范围决定。
具体地，可以将该用户在一段时间内按压任意控件的压力值分为几个范围，上述触控压力值所属的范围为该用户在这一段时间内按压任意控件的压力值所属的频率最高的范围，具体可参考前述实施例中关于如何确定触控压力值部分的相关描述，此处不再赘述。
关于用户年龄，具体可以通过两种方式来确定：
方式一：获取用户的人脸图像，根据用户的人脸图像直接确定用户年龄。
方式二：通过电子设备的字体大小间接确定用户年龄。
具体实现方式可参考图6或图7实施例中的相关描述，此处不赘述。
临界值的具体计算方式可以参考前述实施例中关于介绍临界值的计算方式一和方式二部分的相关描述，此处不赘述。
S403：根据该按压操作的类型确定该按压操作对应的目标事件。
具体地，若按压操作的时长小于上述临界值，则确定该按压操作为短按操作。若按压操作的时长大于或等于上述临界值，则确定该按压操作为长按操作。不同的按压操作对应的目标事件不同。
可能地，第一控件为图3实施例中的相机图标202。对相机图标202输入的按压操作为短按操作时，该按压操作对应的目标事件为开启摄像头193，显示图3中的B所示的用户界面30。对相机图标202输入的按压操作为长按操作时，该按压操作对应的目标事件为在用户界面20中显示图3中的C示出的关于相机应用的功能列表215。
可能地，第一控件为图4实施例中的拍摄控件301。对拍摄控件301输入的按压操作为短按操作时，该按压操作对应的目标事件为拍摄一张照片。对拍摄控件301输入的按压操作为长按操作时，该按压操作对应的目标事件为连续拍摄多张照片。
可能地，第一控件为图5实施例中的照片的缩略图P7。对P7输入的按压操作为短按操作时，该按压操作对应的目标事件为显示用于展示P7对应的照片的用户界面，即图5中的B示出的用户界面50。对P7输入的按压操作为长按操作时，该按压操作对应的目标事件为显示用于选择照片的用户界面，即图5中的C示出的用户界面40。
S404：执行该目标事件。
本申请实施例可以根据用户的年龄计算适用于该用户的临界值，按压时长大于或等于该临界值的按压操作即为长按操作，按压时长小于该临界值的按压操作即为短按操作。短按操作和长按操作对应的目标事件不同。根据该临界值判断用户输入的按压操作的类型，可以避免由于不同年龄的用户对时长定义理解的不同导致电子设备无法准确识别该用户的意图，使电子设备可以对用户输入的按压操作做出准确的响应，降低电子设备误响应的概率，提升用户的输入效率，提升用户体验。
本申请实施例还提供了一种计算机可读存储介质，该计算机可读存储介质中存储有指令，当其在计算机或处理器上运行时，使得计算机或处理器执行上述任一个方法中的一个或多个步骤。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。所述计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行所述计算机程序指令时，全部或部分地产生按照本申请实施例所述的流程或功能。所述计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。所述计算机指令可以存储在计算机可读存储介质中，或者通过所述计算机可读存储介质进行传输。所述计算机指令可以从一个网站站点、计算机、服务器或数据中心通过有线(例如同轴电缆、光纤、数字用户线(DSL))或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。所述计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可用介质集成的服务器、数据中心等数据存储设备。所述可用介质可以是磁性介质，(例如，软盘、硬盘、磁带)、光介质(例如，DVD)、或者半导体介质(例如，固态硬盘(solid state disk，SSD))等。
