Description

受限于技术能力和终端的功耗限制,目前的移动终端在户外强光下显示效果都不是太好,原因是从屏幕本身反射的环境光太强,掺杂在显示屏的图像里,冲淡了显色颜色,降低了显示对比度。对于手机等移动终端很多时候是在户外强光下使用的,此时由于屏幕本身存在镜面反射,目前比较的好的设计依然后5%左右的反射,如果在户外10万lux的环境光光强照射下,屏幕的反射亮度将达到几百尼特。而显示屏的亮度也就几百尼特。此时图像光和反射光混在一起,严重降低了显示图像的色彩表现和对比度,造成显示效果下降,使得用户难以看清屏幕。

附图说明
图1为本发明提供的移动终端的颜色显示方法较佳实施例的流程图。
图2为本发明提供的移动终端的颜色显示系统较佳实施例的结构框图。
本发明的最佳实施方式
本发明提供一种移动终端的颜色显示方法及系统,为使本发明的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
请参阅图1,图1为本发明提供的移动终端的颜色显示方法较佳实施例的流程图,如图所示,所述方法包括以下步骤:
步骤S100、检测移动终端所处环境的环境光光强;
步骤S200、根据所述环境光光强计算颜色增强比例因子;
步骤S300、根据所述颜色增强比例因子对应增强移动终端的颜色显示。
下面结合具体的实施例对上述步骤进行详细的描述。
在步骤S100中,检测移动终端所处环境的环境光光强。具体来说,可在移动终端上设置光强感应器来检测移动终端所处环境的环境光光强,光强的单位是lux(勒克斯),获取移动终端所处环境的环境光光强有多种实现方式,此处不做过多描述。
在步骤S200中,根据所述环境光光强计算颜色增强比例因子。具体来说,目前色彩增强是显示屏广泛采用的技术,它可以使显示颜色更鲜艳,但会导致失真。通常根据终端设计者的需求,增强的比例因子可以调整。通常选取一个折中的固定值来保证在室外室内显示的颜色失真在可接受范围内。而本发明则将该因子与环境光强度结合起来。由于户外的环境光主要是日光,是白色或接近白色,环境光会冲淡显示的颜色,造成颜色的饱和度下降。环境光越强,饱和度下降越多。
根据这一原理,在实际应用时,本发明提供了如下公式来动态管理颜色增强比例因子,从而缓解饱和度下降。所述步骤S200具体包括:
S210、将环境光光强L与预先设置的第一环境光光强值L0进行比较,当L<L0时,颜色增强比例因子a为预先设置的第一颜色增强比例因子为a0;当L≥L0时,颜色增强比例因子a= Min[a0+(L-L0)/Lmax,1],其中,Lmax为颜色增强最大时的环境光强度值。
具体来说,当L≥L0,a=Min (a0+(L-L0)/Lmax, 1);当L<L0,a=a0;其中a是颜色增强归一化比例因子;a0是初始值,当在室内环境光强度L=L0时,a=a0;Lmax是定义的颜色增强最大时的环境光强,环境光超过该光强,可能是一些意外光强环境,颜色增强不再变化,保持在最大值。当L>L0时,颜色增强比例因子a取a0+(L-L0)/Lmax和1之间的较小值,也就是Min()函数的意义。
在步骤S300中,根据所述颜色增强比例因子对应增强移动终端的颜色显示。具体来说,目前色彩增强是显示屏广泛采用的技术,增强的比例因子通常选取一个折中的固定值来保证在室外室内显示的颜色失真在可接受范围内。因此,本发明将颜色增强比例因子与环境光光强结合起来,得到的颜色增强比例因子按照现有的色彩增强技术对应增强移动终端的颜色显示。如何进行颜色增强,本发明简单说明如下。
具体颜色增强过程,以HSV空间为例。转换到其它色彩空间也类似。首先从RGB转换到HSV空间:H参数表示色彩信息,即所处的光谱颜色的位置。该参数用一角度量来表示,红、绿、蓝分别相隔120度。互补色分别相差180度。饱和度S为一比例值,范围从0到1,它表示成所选颜色的纯度和该颜色最大的纯度之间的比率。S=0时,只有灰度。V表示色彩的明亮程度,范围从0到1。有一点要注意:它和光强度之间并没有直接的联系。
具体转换如下:RGB转化到HSV的算法:
max=max(R,G,B)
min=min(R,G,B)
if R = max, H = (G-B)/(max-min)
if G = max, H = 2 + (B-R)/(max-min)
if B = max, H = 4 + (R-G)/(max-min)
H = H * 60
if H < 0, H = H + 360
V=max(R,G,B)
S=(max-min)/max
颜色增强过程:
对RBG转后到HSV空间后的S分量进行处理,如下:
S’= Min (S * (1+a), 1),其中a是颜色增强归一化比例因子;
得到饱和度增加后的新的S分量,S’;S’的最大值是1,依然是归一化的。
然后再对HS’V处理,转化到RGB:
if S’ = 0
R=G=B=V
else
H /= 60;
i = INTEGER(H)
f = H - i
a = V * ( 1 – S’ )
b = V * ( 1 – S’ * f )
c = V * ( 1 – S’ * (1 - f ) )
switch(i)
case 0: R = V; G = c; B = a;
case 1: R = b; G = v; B = a;
case 2: R = a; G = v; B = c;
case 3: R = a; G = b; B = v;
case 4: R = c; G = a; B = v;
case 5: R = v; G = a; B = b;
颜色增强处理完毕。
为了提高显示屏的显示效果,进一步地,所述步骤S200还包括:
S220、检测移动终端的显示屏是否工作在最大色域,若为否,则根据所述环境光光强和移动终端显示屏当前工作的色域模式计算移动终端显示屏待工作的色域。
具体来说,关于色域模式,显示屏可工作在标准模式或SRGB模式等,这些都是现有技术中常用的色域模式。对于部分显示屏,如果其采用了高色域屏和色域管理技术,本发明可在其基础上引入环境光变化因素来管理。当显示屏工作在最大色域时,比如色域值为S0, 环境光不会引起色域任何变化,依旧保持最高色域S0;当基于某些原因(真实显示或品牌特色显示),显示屏工作在色域模式S1时,色域值S1小于S0,便可根据环境光来动态调整色域,色域增大意味着颜色饱和程度提高,同样可以缓解由于环境光造成的饱和降低问题。
在实际应用时,所述步骤S220具体包括:
S221、当移动终端显示屏没有工作在最大色域时,根据所述环境光光强L计算移动终端显示屏对应的色域因子b;当L<L0时,色域因子b=0;当L≥L0时,色域因子b= Min [(L-L0)/Lmax,1];其中,L0为预先设置的第一环境光光强值,Lmax为颜色增强最大时的环境光强度值;
S222、计算移动终端显示屏待工作的色域S = S1+b*(S0-S1),其中, S0为显示屏工作在最大色域时的色域值; S1为显示屏当前工作的色域模式对应的色域值。
具体来说,当L≥L0时,色域因子b为(L-L0)/Lmax与1之间的较小值,这是Min()函数的意义。就是根据移动终端显示屏当前工作的色域模式和环境光光强计算移动终端显示屏待工作的色域,再对应调节显示屏的工作色域,从而实现动态调节显示屏的色域,缓解由于环境光造成的饱和降低问题,提高户外显示效果。
进一步地,所述步骤S300还包括:S310、根据计算得到的移动终端显示屏待工作的色域,对应调节移动终端显示屏工作的色域。具体来说,色域调节,是一种数字变换的方式。根据色彩空间转换理论,如果要在最大S0色域的显示屏上显示出S色域的显示效果时,需要将该色域空间的数字图像先变换到与设备无关的色彩空间,比如CIE XYZ空间,在这个空间基础上,根据S0色域的具体三基色的色坐标,可以得到一个转换矩阵,比如H。在此基础上,对于色域空间S的具体图像,先做预处理,然后转换到CIE XYZ空间,之后与高色域空间S0的转换矩阵H进行运算,再进行后处理,即可实现色域模式S的效果。具体流程如下,先得到目标色域S[R,G,B],然后预处理矩阵运算到CIE XYZ空间[X,Y,Z],再根据转换矩阵H转换为原始色域S0[R’,G’,B’],后处理为显示色域S[R,G,B],则可实现最大色域空间为S0的显示硬件上显示出色域空间S的显示效果。
本发明提供的移动终端的颜色显示方法,是一种自适应的图像处理方法,能够在不显著增加功耗和保证显示效果的前提下,根据环境光的强弱来动态调整颜色增强,进一步地还可调节色域范围,可以在不影响室内弱光下显示效果的前提下,提高了户外显示效果。
