Description

一种调整屏幕亮度的方法及设备
本申请要求于2017年07月18日提交中国专利局、申请号为201710586434.8、申请名称为“一种调整屏幕亮度的方法及设备”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
本发明实施例涉及终端设备领域，尤其涉及一种调整屏幕亮度的方法及设备。
背景技术
随着终端设备功能的日益强大，用户安装的应用也越来越多。为了满足用户长时间的使用安装的应用的需求，可以通过降低终端设备的屏幕亮度的方式以降低终端设备的功耗，从而达到延长终端设备续航时间的目的。
在降低终端设备的屏幕亮度的过程中，必须解决两个关键问题：(1)亮度变化的过程必须是线性的，保证亮度调整的过程不会出现亮度跳变和屏幕闪烁的问题；(2)亮度调整的过程必须在一定的有限时间内完成，亮度调整时长太长时，会导致用户感知度提升，造成用户体验变差。
目前现有技术中，是采用自动亮度调整方案对终端设备的屏幕亮度进行调整，该自动亮度调整方案是基于环境光的变化进行调整的。具体的，终端设备可以自动感应所处不同环境的光线强度，从而自动调整屏幕亮度。
但是，现有的亮度调整方案并不能针对终端设备的不同应用场景进行不同的屏幕亮度调整。

可选的，触摸屏121可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器13，并能接收处理器13发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触摸屏121。其他输入设备122可以包括但不限于物理键盘、功能键(比如音量控制按键、电源开关按键等)、轨迹球、鼠标以及操作杆等中的一种或多种。

其中，处理器13可以利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器14内的软件程序和/或模块，以及调用存储在存储器14内的数据，执行手机01的各种功能和处理数据，从而对手机进行整体监控。
可选的，在具体的实现中，作为一种实施例，处理器13可以包括一个或多个CPU。
可选的，在具体实现中，作为一种实施例，手机01可以包括多个处理器，即手机01可以包括多核处理器。这些处理器中的每一个可以是一个单核处理器(Single-CPU)， 也可以是一个多核处理器(Multi-CPU)。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。

在另外的一些实施例中，上述触摸屏121还可以设置有压力感应传感器，这样用户在上述触摸屏121上进行触摸操作时，触摸屏121还能检测到该触摸操作的压力，进而手机01能够更准确地检测该触摸操作。
进一步的，手机01还可以包括至少一种传感器，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近光传感器。其中，环境光传感器可根据环境光线的明暗来调节显示面板151的亮度；接近光传感器可以检测是否有物体靠近或接触手机，可在手机01移动到耳边时，关闭显示面板151和/或背光，这样手机01可以进一步节省电量。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等。手机01还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。

其中，第一应用为当前显示界面所属的应用。
其中，当用户对终端设备的触摸屏进行触摸操作时，终端设备的触摸屏可以检测到用户对触摸屏的触摸操作，并将根据触摸操作产生的相关参数发送至终端设备的处理器。处理器在接收到参数之后，根据该参数将处于触摸操作对应区域中的对象确定为触摸对象。
示例性的，当用户对手机01的显示界面中的第一应用的图标进行按压操作时，手机01的触摸屏121可以检测到该按压操作，并将根据该按压操作所产生的参数发送至手机01的处理器13。处理器13在接收到该参数之后，可以根据该参数确定用户进行按压操作的对象为第一应用的图标；然后处理器13控制显示面板151显示第一应用，使得用户可以在当前显示界面上看到第一应用；处理器13确定第一应用的类型，并根据第一应用的类型确定应用场景。
例如，当用户对手机01的显示界面中的“微信”图标进行按压操作后，手机01的处理器13确定用户进行按压操作的对象为“微信”，并确定“微信”的类型为即时消息类应用，然后处理器13根据“微信”的类型确定应用场景为即时消息场景。
示例性的，本发明实施例中的应用场景可以包括以下至少一种：浏览器场景、游戏场景、视频场景、即时消息场景、照相场景以及电子书场景。本发明实施例中的应用场景包括但不局限于上述应用场景，此处不再一一列举。
例如，第一应用为“**浏览器”时，则对应的应用场景为浏览器场景；第一应用为“**视频”时，则对应的应用场景为视频场景；第一应用为“QQ”或“微信”等时，则对应的应用场景为即时消息场景。
S202、终端设备根据应用场景以及预设的应用场景与调整曲线之间的对应关系，确定与应用场景对应的调整曲线。
其中，应用场景与调整曲线一一对应，即一种应用场景对应一个调整曲线。
示例性的，终端设备的处理器可以预先设定每种应用场景与调整曲线的对应关系，并保存至存储器中。用户启动第一应用后，终端设备的处理器确定了应用场景，并根据该应用场景在存储器中查找该应用场景与调整曲线的对应关系，然后再根据该应用场景以及该应用场景与调整曲线的对应关系，从调整曲线中查找到与该应用场景对应的调整曲线。
由于在屏幕亮度较低的情况下，人眼对亮度变化更为敏感，所以在屏幕亮度较暗时，屏幕亮度渐变的时间应该越长，跳变的步长应该较小，而在屏幕亮度较亮的时候，屏幕渐变的时间就应该更短，跳变的步长较长。例如，假设屏幕亮度的变化值为20，当屏幕亮度从200降到180时，用户可能感知并不明显；但是，当屏幕亮度从60降到 40时，用户就会明显感觉到屏幕亮度在变暗。基于这样的特性，采用的调整曲线应该具有这样的特征：屏幕亮度较亮时，曲线斜率应该较大，屏幕亮度变化速率较快；而屏幕亮度较暗时，曲线斜率应该较小，屏幕亮度变化速率较慢。为了保证屏幕亮度调整的过程中，屏幕亮度的变化为渐变式的，实现屏幕亮度的平滑调整，本发明实施例采用线性方式调整屏幕亮度。因此，本发明实施例采用的调整曲线为二次函数y＝ax 2+bx+c，其中，y为屏幕亮度，x为亮度调整时间，a、b和c为上述二次函数的基本参数。
例如，假设手机01的处理器13预先设定浏览器场景与调整曲线1(即y 1＝a 1x 1 2+b 1x 1+c 1)对应，视频场景与调整曲线2(即y 2＝a 2x 2 2+b 2x 2+c 2)对应，即时消息场景与调整曲线3(即y 3＝a 3x 3 2+b 3x 3+c 3)对应。用户启动第一应用的为“微信”后，手机01的处理器13确定的应用场景为即时消息场景，处理器13根据确定的即时消息场景以及预先设定的即时消息场景与调整曲线的对应关系，确定与即时消息场景对应的调整曲线为y 3＝a 3x 3 2+b 3x 3+c 3。
S203、终端设备采用与应用场景对应的调整曲线调整屏幕亮度。
示例性的，本发明实施例可以采用二次函数y＝ax 2+bx+c调整屏幕亮度，该二次函数的定义域为[0,T]，值域为[B min,B max]。其中，y为屏幕亮度，x为亮度调整时间，T为亮度调整时长，B min为第一目标亮度，B max为第一应用的当前亮度。并且，针对不同的应用场景，终端设备采用的二次函数y＝ax 2+bx+c不同，即不同的应用场景对应的二次函数的参数(a、b和c)不同。
具体的，终端设备的处理器可以采用二次函数y＝ax 2+bx+c，将屏幕亮度从开始(0时刻)的B max调整至T时刻的B min，该二次函数经过两个特殊点，即(0,B max)和(T,B min)。根据上述二次函数经过两个特殊点可得到以下两个方程：
B max＝a*0 2+b*0+c (1)
B min＝a*T 2+b*T+c (2)
根据方程(1)和(2)可以得到等式：c＝B max (3)。
由于上述二次函数在定义域内具有单调性，当屏幕亮度降低时该二次函数单调递减，当屏幕亮度增加时该二次函数单调递增。根据上述二次函数在定义域内的单调递减，可以得到上述二次函数的对称轴在直线x＝T的右边或者与直线x＝T重合，即
Figure PCTCN2018095924-appb-000006
假设取
Figure PCTCN2018095924-appb-000007
则可以得到以下等式：b＝-2aT(4)。将(3)式和(4)式代入到方程(2)中，可以得到
Figure PCTCN2018095924-appb-000008
如图3所示，为本发明实施例采用调整曲线为二次函数的实例示意图。
由此可以得出：当第一应用的当前亮度、第一目标亮度和亮度调整时长确定后，便可以确定二次函数的基本参数a、b和c，从而得到渐变式调整函数(即二次函数)。
例如，假设应用场景为浏览器场景，第一应用的当前亮度为180，第一目标亮度为90，亮度调整时长为10s，则浏览器场景对应的渐变调整函数为：y＝0.9x 2-18x+180。如图4所示，假设浏览器场景、视频场景、即时消息场景以及游戏场景的当前亮度分别为180、120、90和70，第一目标亮度分别为90、60、45、35，亮度调整时长均为 10s，则上述应用场景对应的渐变调整函数分别为y＝0.9x 2-18x+180、y＝0.6x 2-12x+120、y＝0.45x 2-9x+90和y＝0.35x 2-7x+70，分别对应图4所示的曲线(a)、(b)、(c)和(d)。
由于终端设备采用的调整曲线的在定义域内具有单调性，因此终端设备在调整屏幕亮度过程中，不会出现屏幕亮度忽明忽暗的现象。
当然，本发明实施例提供的调整屏幕亮度的方法，还可以针对不同的应用场景恢复屏幕亮度。示例性的，终端设备的处理器可以采用二次函数y＝ax 2+bx+c，将屏幕亮度从开始(0时刻)的B min调整恢复至T时刻的B max，该二次函数经过两个特殊点，即(0,B min)和(T,B max)。根据上述二次函数在定义域内的单调递增，可以得到上述二次函数的对称轴在直线x＝0的左边或者与直线x＝0重合，即
Figure PCTCN2018095924-appb-000009
如此便可以得到：
Figure PCTCN2018095924-appb-000010
例如，假设应用场景为浏览器场景，从第一目标亮度90恢复到第一应用的当前亮度180的屏幕亮度恢复渐变调整函数为：y＝0.9x 2+90。如图5所示，假设浏览器场景、视频场景、即时消息场景以及游戏场景的第一目标亮度分别为90、60、45、35，当前亮度分别为180、120、90和70，亮度调整时长均为10s，则上述应用场景对应的屏幕亮度恢复渐变调整函数分别为y＝0.9x 2+90、y＝0.6x 2+60、y＝0.45x 2+45和y＝0.35x 2+35，分别对应图5所示的曲线(e)、(f)、(g)和(h)。
例如，假设终端设备所处的环境下浏览器场景和视频场景的当前亮度分别为180和120，且对屏幕亮度的需求分别为90和60。
现有技术中，当第一应用为浏览器场景时，终端设备根据环境光的亮暗程度将浏览器场景下的屏幕亮度调整至90；当第一应用为视频场景时，终端设备根据环境光的亮暗程度将视频场景下的屏幕亮度调整至90。但是，由于视频场景对屏幕亮度的需求为60，而终端设备将视频场景下的屏幕亮度调整至90，因此导致终端设备的功耗的浪费。
而本发明实施例中，当第一应用为浏览器场景时，终端设备采用浏览器场景对应的调整曲线将屏幕亮度调整至90；当第一应用为视频场景时，终端设备根据采用视频场景对应的调整曲线将屏幕亮度调整至60。如此可以看出：本发明实施例中终端设备能够进一步的降低终端设备的功耗。
本发明实施例提供一种调整屏幕亮度的方法，终端设备可以根据确定的应用场景，采用所述与该应用场景对应的调整曲线调整屏幕亮度。由于每种应用场景对屏幕亮度的需求不同，如果仅根据环境光的变化降低终端设备的屏幕亮度，对于对屏幕亮度的需求较小的应用场景，则会导致功耗的浪费，因此本申请中的终端设备针对不同的应用场景，采用的调整曲线调整屏幕亮度，可以避免终端设备的功耗的浪费，进一步的降低终端设备的功耗，从而延长终端设备的续航时间。
由上述实施例可以看出，当第一应用的当前亮度、第一目标亮度和亮度调整时长确定后，便可以确定二次函数的参数a、b和c，从而得到终端设备采用的调整曲线。本发明实施例中，终端设备可以预先设定应用场景与亮度调整系数之间的对应关系以及参考调整曲线，以便确定第一目标亮度和亮度调整时长。
具体的，如图6所示，其示出了本发明实施例提供的另一种调整屏幕亮度的方法，与图2所示的调整屏幕亮度的方法相比，主要是用S202a和S202b替换了S202，在此只对不同的地方进行详细说明，参见图6，该调整屏幕亮度的方法包括：
S201、终端设备根据第一应用的类型确定应用场景。
S202a、终端设备根据应用场景以及应用场景与亮度调整系数之间的对应关系确定亮度调整系数。
其中，亮度调整系数用于终端设备确定第一目标亮度。应用场景与亮度调整系数一一对应，即一种应用场景对应一个亮度调整系数。终端设备的处理器可以预先设定每种应用场景与亮度调整系数的对应关系，并将该对应关系保存至存储器中。
示例性的，终端设备的处理器可以根据确定的应用场景，在存储器中查找该应用场景与亮度调整系数的对应关系，然后根据该应用场景以及应用场景与亮度调整系数的对应关系，从亮度调整系数中查找到与该应用场景对应的亮度调整系数。
示例性的，本发明实施例中的亮度调整系数可以为屏幕亮度的“折扣率”，浏览器场景对应的亮度调整系数为0.65(即折扣率为0.65)，游戏场景对应的亮度调整系数为0.9，视频场景对应的亮度调整系数为0.85，即时消息场景对应的亮度调整系数为0.8，照相场景对应的亮度调整系数为0.85，以及电子书场景对应的亮度调整系数为0.7。本发明实施例中每种应用场景与亮度调整系数的对应关系，并不局限于上述对应关系，此处不再一一列举。
例如，本发明实施例中的亮度调整系数可以为屏幕亮度的“折扣率”，假设手机01的处理器13预先设定浏览器场景与亮度调整系数1对应的，视频场景与第二亮度调整系数2对应，游戏场景与亮度调整系数3对应。处理器13在确定应用场景为浏览器场景后，可以根据预先设定的浏览器场景与亮度调整系数的对应关系(即浏览器场景与亮度调整系数3对应)，确定出与浏览器场景对应的亮度调整系数为0.65。
S202b、终端设备根据亮度调整系数以及预设的参考调整曲线确定与应用场景对应的调整曲线。
其中，预设的参考调整曲线用于终端设备确定亮度调整时长。
示例性的，终端设备的处理器根据亮度调整系数以及预设的参考调整曲线确定与应用场景对应的调整曲线的方法具体可以包括步骤S202c、S202d和S202e：
S202c、终端设备的处理器可以根据第一应用的当前亮度以及亮度调整系数确定第一目标亮度。
具体的，终端设备的处理器可以采用公式
Figure PCTCN2018095924-appb-000011
计算得到第一目标亮度，其中，
Figure PCTCN2018095924-appb-000012
为亮度调整系数，B min为第一目标亮度，B max为第一应用的当前亮度。其中，终端设备的处理器可以在确定应用场景后，获取到第一应用的当前亮度。
例如，手机01的处理器13可以获取到浏览器应用的当前亮度为200，并确定浏览器场景对应的亮度调整系数为0.65，则处理器13计算得到的第一目标亮度为200×0.65＝130。
S202d、终端设备的处理器可以根据第一应用的当前亮度、第一目标亮度以及预设的参考调整曲线确定亮度调整时长。
其中，终端设备可以预先获取预设的参考调整曲线。具体的，终端设备的处理器 可以确定从起始亮度调整至第二目标亮度的亮度调整时长T 0，并根据起始亮度、第二
其中，B 0、第二目标亮度以及T 0均为在亮度调整过程中，保证用户的感知度较小的实验值，即在每种应用场景下，终端设备的处理器在T 0时长内完成将屏幕亮度从B 0调整至第二目标亮度(如B 1)时，用户的感知度较小。
因此，为了保证用户的感知度较小，终端设备的处理器在确定任一种应用场景对应的亮度调整时长时，只要保证根据第一应用的当前亮度B max、第一目标亮度B min以及亮度调整时长T确定的一次函数的斜率与
Figure PCTCN2018095924-appb-000014
相等，便可以计算得到亮度调整时长T。具体的，一次函数y＝k*x+b过两个特殊点，即(0,B max)和(T,B min)，可以得到
Figure PCTCN2018095924-appb-000015
其中，
Figure PCTCN2018095924-appb-000016
如此便可以得到：
Figure PCTCN2018095924-appb-000017
S202e、终端设备的处理器可以根据第一应用的当前亮度、第一目标亮度以及亮度调整时长确定与应用场景对应的调整曲线。
其中，当第一应用的当前亮度、第一目标亮度和亮度调整时长确定后，便可以确定二次函数的参数a、b和c。
由上述实施例可知，终端设备的处理器采用的调整曲线为二次函数y＝ax 2+bx+c，且

终端设备的处理器确定的亮度调整时长
Figure PCTCN2018095924-appb-000019
因此，终端设备的处理器可以确定与应用场景对应的调整曲线为
Figure PCTCN2018095924-appb-000020
S203、终端设备采用与应用场景对应的调整曲线调整屏幕亮度。
其中，由于本发明实施例中，B 0、第二目标亮度以及T 0均为在亮度调整过程中，保证用户的感知度较小的实验值；并且亮度调整时长T是由终端设备根据确定的一次
Figure PCTCN2018095924-appb-000021
整过程中，用户对屏幕亮度变化的感知度不明显，提升了用户的体验。
