浅谈监视器与色彩管理之二

检测标准与计算方法

     在分析图像数据之前,我们先了解一下评判色彩表现的理论依据是什么,也就是评判的标准。这有助于我们接下来通过图表的方式,快速理解各项指标的实际含义和作用。

     将监视器的原始色域与目标色域之间的色差,定义为色彩偏离度,用颜色空间中两个色点之间的距离来表示。通过计算后得到其数值,一般以符号△E来代表。
    
国际照明委员会(CIE)在2001年推广△E的标准计算方法。△E可以规范出人们感知内所能接受的色差范围。  

E各阶段的含义:

E =1.6-3.2,人眼基本上分辨不出色彩的差异,通常被认为是相同的颜色;
E =3.2-6.5,多数人感到色彩是相同的,但经过专业的训练可以辨别其不同色彩的差别是可以看到的,但色彩给人的印象是基本相同;
E =6.5-13,色彩的差别是可以判别的,但色调本身仍然相同;
E =13-25,可以确认是不同的色调,但也可以辨别出色彩的从属(属性);
E 大于25时,则被认为是另一种不同的颜色。

     通常来讲,E位于36之间的变化是可以被接受的。作为技术级监视器,色彩偏离度控制在△E3以内,是比较理想的技术指标。而作为监看级监视器,E的偏离值以不能大于6.为宜。

     大致了解了相关色彩偏离度的检测标准后,也许大家要问,用什么方法来检测监视器的各项显示呢?其实这也是我们的顾虑。因为这是一篇技术交流的文章,意在抛砖引玉,投石问路,不想有任何的广告植入。但界面截图中会有相关公司的LOGO,同时也为了说明该色彩管理系统的可信度,还是要把该系统做一个简单的介绍。如有反感,纯属无奈。

     总部位于西雅图的SpectraCal,是美国最具影响力的专业视频校正软件设计公司。为松下、JVCREDTvlogic、迪斯尼动画、苹果、艺卓等国际知名品牌提供了专业的色彩管理方案。

(截图来自SpectraCal公司官方网站)

     CalMAN5SpectraCal的专业色彩管理软件,设计师将E的换算定义,用图表、直方图和水平线的方式予以描述,这样就可以更直观的看到以往我们在监视器中所看不到的关键数据,简单易懂,一目了然。

     我们在软件的色域模式选项中,选择了REC-709的色域作为测试基准,看一下监视器的原始色域与目标色域的关系:(见图10

10

     这是一幅色域图,左边是RGB的平衡直方图,中间是亮度、色度、色相的直方图,而右边的图形则是REC-709在色度图中的色域范围。

     从这幅色域局部图中我们可以看出,三角图形周边的六个小方框,代表的是REC-709色域中三原色和三补色的目标值,方框中的圆点,则表示的是测量值,而中心部位的方框,代表的是白色坐标。所有圆点完全打进方框内,说明这台监视器的原始色域是完全覆盖REC-709色域范围的。也就是说,它可以100%的还原高清信号的色彩信息。

     现在我们用一台原始色域较小的监视器来显示REC-709色域,所能再现的颜色范围将是有限的。如果RGB的平衡没有做好的话,不仅色度偏低,还会出现偏色现象。(见图11

11

     从局部图中可以看出,测量值(圆点)与目标值(方框)存在一定的距离,没有安全打进目标值的靶心。证明这台监视器的原始色域不能满足REC-709的色域要求,也就无法做到准确的色彩还原。

     为了让大家对于原始色域的概念有更深刻的理解,我们截取了一幅色度图,从另一角度来理解为什么在某些情况下,色饱和度会低的原因。

     此前,一位电视台的技术部主任向我们提问,他们在演播室3200K的灯光下调白后,通过监视器观看播音员的肤色是正常的,当穿上蓝色服装后,蓝色里面就出现了紫色,而不是纯蓝色。起初一直怀疑是色温偏低造成的,如果在5400K的色温下,是不是就正常了呢?之后我让他看了一下色度图,他马上就明白了造成这种现象的原因。(见图12

12

     这是一幅色度图,局部图中的红、绿、蓝、黄、青、品(也称紫),呈放射状,代表着每种颜色的基本属性(即色相)。而每一条线上有5个目标值方格,从中心向外延伸,分别表示从20%100%的饱和度(即色度)。

     我们可以看到,做了黄色圆形标记的位置,就是该监视器所能提供的最大色域,尤其是蓝色,其原始色域仅为目标色域的80%左右。而播音员的服装是纯蓝色,也就是接近100%饱和色,由于原始色域不能满足80%以上的蓝色需求,RGB得不到平衡,最终导致在监视器中所看到颜色与主观目测的结果出现了偏差。

     那为什么肤色是正常的呢?这个问题很简单,现场布光是以播音员的肤色为主光区,而播音员的脸部位置,是不存在高饱和度的颜色,没有见过哪个播音员是涂着进舞厅的口红去上镜的。因此,播音员的肤色是处于监视器原始色域的覆盖范围之内。如图所示,80%以内的颜色是可以被还原的。换句话说,同样是蓝色,牛仔裤的颜色一定会被还原正常的。

     之所以在拍摄之前要校准白平衡,实际上就是让RGB等量相加。如果监视器的原始色域在某一个阶段不能提供等量的颜色,那么基准白就得不到平衡,色相就会向缺失的另一个方向偏移。这就是我们经常看到的,在同一个画面中,有的颜色还原正常,而有的颜色却出现偏色的原因。理论上讲,监视器原始色域缺失的部分,是无法对其校准的。
