本申请要求在2014年9月10日向中国国家知识产权局提交的申请号为201410458183.1的优先权，并在此全部引用。
技术领域
本发明涉及照明控制技术领域，特别涉及一种调节室内光亮度的方法、装置和智能家居控制系统。
背景技术
人眼从观看显示装置的较亮画面到较暗画面时，会用一段时间来适应亮度的变化；同样，人眼从观看显示装置的较暗画面到较亮画面时，也需要一段时间来适应。通常将人眼的状态适应明暗条件变化的过程叫做亮度适应，其中，人眼适应从亮到暗变化的过程叫暗适应，人眼适应从暗到亮变化的过程叫亮适应。亮适应只需要几秒(通常小于一分钟)就能完成；但是暗适应却要经历较长的过程，根据起始亮度不同，人眼的暗适应调节时间通常需要5分钟以上。
当用户观看显示装置时，随着显示装置显示内容的变化，显示装置的屏幕亮度也会实时发生变化。当用户在室内观看显示装置时，由于室内光线的亮度保持不变且无法调节，因此当显示装置的屏幕亮度与室内光线的亮度反差较大时，为同时适应显示装置的屏幕亮度和室内光线的亮度，人眼的瞳孔需要不停地调节，以便于适应亮至暗、亮至暗的变化，这势必会造成人眼的瞳孔调节滞后于亮度变化，此时显示装置的屏幕亮度的变化将对人眼产生较大的刺激，从而对人眼造成伤害。

附图说明
图1为本发明实施例一提供的一种调节室内光亮度的方法的流程图；
图2为本发明实施例二提供的一种调节室内光亮度的装置的结构示意图。
具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图对本发明提供的调节室内光亮度的方法、装置和智能家居控制系统进行详细描述。
图1为本发明实施例一提供的一种调节室内光亮度的方法的流程图，如图1所示，该方法包括：
步骤101、对显示装置进行检测得到显示装置的亮度。
本实施例中的各步骤可以由调节室内光亮度的装置来执行。显示装置可以为液晶显示装置或者有源矩阵有机发光二极管(Active Matrix/Organic Light Emitting Diode，简称：AMOLED)显示装置。
随着显示装置显示内容的变化，显示装置的亮度也会实时发生变化，本步骤可实现实时检测显示装置的亮度。具体地，可按照设定时间间隔t0对显示装置进行检测，得到显示装置的多个时刻的亮度。其中，可预先设置检测显示装置亮度的设定时间间隔t0，优选地，该设定时间间隔t0可根据显示装置的刷新频率或换帧频率F进行设置。当根据显示装置的刷新频率或换帧频率F设置设定时间间隔t0时，该设定时间间隔t0可以为t0＝N/F其中，N为正整数。例如：若刷新频率或换帧频率为60Hz且N＝1时，则设定时间间隔t0为
Figure PCTCN2015070112-appb-000001
假定按照设定时间间隔t0分别在tn-m、tn-(m-1)……tn-1、tn时刻对显示装置进行检测，则得出上述各个多个时刻的显示装置的亮度LD(tn-m)、LD(tn-(m-1))……LD(tn-1)、LD(tn)。其中，1≤m<n，n≥2且m、n均为正整数。其中，tn-tn-1＝t0，t0为常量，也就是说本实施例优选采用等时间间隔的时刻对显示装置的亮度进行检测。但在实际应用中，也可适应性调整t0的大小而采用非等时间间隔的时刻对显示装置的亮度进行检测。 步骤102、根据显示装置的亮度生成室内光亮度。
本步骤具体包括：
步骤1021、对显示装置的多个时刻的亮度进行加权平均处理，生成下一时刻的显示装置的亮度。
例如根据下一时刻tn+1之前的连续m个时刻的显示装置的亮度LD(ti)加权平均得到显示装置下一时刻tn+1的亮度LD(tn+1)：
Figure PCTCN2015070112-appb-000002
本实施例可通过检测出的显示装置的多个时刻的亮度，预测出显示装置的下一时刻的亮度。并且采用上述加权平均处理的方法计算出的显示装置的下一时刻的亮度更加均匀和准确，从而能够更好地调节室内光亮度。
步骤1022、将显示装置的下一时刻的亮度与预先设定的亮度系数相乘，生成室内光亮度。
室内光亮度LE(tn+1)＝kLD(tn+1)，其中，k为亮度系数。亮度系数k可自行设定，k可以在0.8至1.2之间取值。为使得室内光亮度接近于显示装置的亮度，k越接近1越好，因此优选地k＝1。
本实施例可通过预测出的显示装置的下一时刻的亮度，计算出室内光亮度。
步骤103、根据室内光亮度对室内照明装置的亮度进行调节。
本步骤具体包括：
步骤1031、从预先设置的亮度对应关系表中，查询出与室内光亮度对应的亮度等级，亮度对应关系表包括室内光亮度与亮度等级的对应关系。
预先设置的亮度关系表可参照表1：
表1
亮度等级 室内光亮度LE(Lux)
L1 0.1≤LE≤10
L2 10＜LE≤50
L3 50＜LE≤100
L4 100＜LE≤200
L5 200＜LE≤300
本实施例可将需要调节的室内光线分为多个等级，每个等级对应于一个亮度等级。如上表1所示，可以将需要调节的室内光线分为5个等级(当然根据需要也可以设置更多或更少的亮度等级个数)，该5个等级分别对应于亮度等级L1、L2、L3、L4和L5。并预先建立室内光亮度与亮度等级的对应关系，以形成亮度对应关系表。例如：若步骤102中生成的室内光亮度为5Lux，则从表1中可查询出对应的亮度等级为L1。
步骤1032、将室内照明装置的亮度调节至与室内光亮度对应的亮度等级。
本实施例中，照明装置可以为白炽灯、荧光灯或者发光二极管(Light Emitting Diode，简称：LED)灯。
本实施例提供的调节室内光亮度的方法的技术方案中，对显示装置进行检测得到显示装置的亮度，根据显示装置的亮度生成室内光亮度，根据室内光亮度查表得到亮度等级，根据查表得到的亮度等级对室内照明装置的亮度进行调节，本实施例可实现对室内光线亮度的实时调节，减轻显示装置的亮度变化对人眼产生的刺激，从而减小了对人眼造成的伤害。
图2为本发明实施例二提供的一种调节室内光亮度的装置的结构示意图。如图2所示，该装置包括检测模块11、生成模块12和调节模块13。其中，检测模块11、生成模块12和调节模块13依次连接，调节模块13还与室内照明装置连接。
