Abstract
一种用于数字的和HDTV的多格式显示系统包括硬件和算法。该系统包括一个光源(120)，一个调谐器/预处理单元(114)，一个处理单元(116)，一个空间光调制器(118)，以及一个显示表面(128)。该处理器能使数据格式进行换算以用于多种标准化格式的视频广播信号，并能完成附加的内插的消除误差。
Description
本发明特别涉及那些必须支持多视频标准以及使用两维空间光调制器(SLM)作为其光调制元件的显示器。
从五十年代到九十年代早期已产生了几种视频显示制式。随着显示技术向着高清晰等显示(HDD)和高清晰度电视(HDTV)的发展，已出现了许多更标准化的格式。其中某些格式为ATV(先进的电视Advanced Television)或US-HD(美国高清晰度UnitedStatesHigh Definitiox)，可能还有HD-MAC(高清晰度复用的模拟分量)，以及日本的MUSE(多级亚尼奎斯特取样编码方法MultipleSub-Nyquist Sampling Encoding)。这些格式都被认为是高清晰度显示，但是所有这些都有不同的水平线数以及沿着这些线上的不同的分解元素(或象素)数，以及不同的帧速率。
上述的除US-HD以外的所有格式都是模拟的，但是，所述US-HD将以数字式方式实施而且被规定作为任一型号的计算机显示格式。目前将这些大量的数字和模拟的标准以低廉的成本呈现在单个显示制式上的能力是一个重要的性能，但在显示系统的竞争之间还需要差分装置(differentiator)。
连续扫描式显示器，例如CRT，可以持续地显示经一个扫描线上的象素，但是受到监视器的MTF的局限。分离式采样显示器，例如那些以液晶显示器(LCD)或数字微镜显示器(DMD)的SLM为基础的显示器，具有固定的象素布局及纵横比，它们需要对输入的数据加以调整，以使具有不同纵横比，规格以及水平解析度的输入图象以接受的保真度来被显示。在这些装置中，一个图象被显示在单个元素的行和列构成的矩阵上。所述的模拟标准在这些系统中必须被取样，并且预采样的数字标准可能在解析度与SLM的解析度不匹配时被取样。
在构造一个显示系统时存在的问题是随模拟标准不同而不同的，而且要与数字标准数字例如US-HD兼容。如果该系统构造成US-HD兼容的，那么就存在差调整各种模拟标准的问题。由于对于任一其它的标准来说，采样数、纵横比及象素的间距不是一个精密配合，所以需要对数据进行再采样或换算。整个显示系统的复杂程度，包括图象处理系统以及SLM系统，将取决于SLM设计与处理算法之间的协调性。在这种协调过程中，要考虑模糊，低劣图象质量及费用昂贵等问题。
本发明的目的在于解决空间光调制器设计和算法之间协调的难题，使空间光调制器和算法一起工作以在同样象素的显示系统上呈现HD和标准分辨率的多视频标准。
这一系统包括能使数据与所选择的几个可能的格式之一相匹配的处理单元以及一个使用所述数据的空间光调制器，以便当该调制器被照亮时，它能按所希望的格式形成一个图象。
为了对本发明及其优点有更全面的理解，现在对照下列附图对本发明作详细的说明。

图1示出一种多格式显示系统的一种可能的结构。系统110包括一个调谐器/预处理单元114，一个处理单元工16，一个空间光调制器118，照明源120，显示表面128，以及光学系统122和124，但系统110并不局限于此。输入的信号经线路112进入到该系统中。根据视频传递方法，即是发射的(电线，电缆)还是传布的(CD，录相带)，以及根据该视频生产的地域(US，日本、欧州)，所输入的信号将具有广泛变化的格式以及信号成分。为讨论方面起见，我们指定该系统的构成是在美国接收经发射传递的数据(即US-HDTV以及NTSC输入)。
该数据进入到该系统之后，它在调谐器/预处理器单元114中被接收和滤波，然后该信号被送到处理单元116中，或者所述处理功能由调谐器/预处理器114以及处理单元116分担。为讨论方面起见，所述功能任意地划分给两个单元。在一个模拟输入信号的情况下，单元114执行信号的数字化并执行信号的任何一种调整例如NTSC解码、彩色空间转换或为了清晰度所执行的滤波等等。
然后该数据送到处理单元116。处理单元116然后将该数据转换成合适的格式用于显示在一个所选择的空间光调制器上。作为一个基准点，假设2048个象素(横向)X1152个象素(纵向)的一个空间光调制器，它对应于目前已提出的用于HDTV的最高分辨率的格式，具有16∶9的纵横比。作为一个例子，如果一个已提议用于US-HD发射的格式的960线数据要被呈现为16∶9的纵横比，那么该数据必须被转移成每线上有1707个象素。数字式处理必须被执行以完成上述转换，即使US-HD是以数字式发射的，＂预象素化＂方式，这是因为该标准的发射比960线的每一线上1500个象素要少。如果不将1500个象素转换成1707个象素，显示会出现一个明显的垂直方向伸长了的物体，伸长程度大约为15％。不管最后哪一种数据格式被选择来用于US-HDTV，如果有非正方形象素的分布的话(这是极可能的，因为6MHzNTSC频道带宽的局限性)，数字式换算将是必要的。
如果一个480线分辨率的标准图象呈现在标准的4∶3纵横比的同一显示器上，输入的信号(它是模拟的，如同大多数已提出的和现有的HD标准一样)通过对在每水平线上640个象素采样能被数字化成合适的纵横比。然后，该被采样的数据在两个方向上被加倍以取得1280×960的显示，或者，数字化之后，采用更复杂的数字技术以产生内插的1280×960象素的图象。
大多数HD发射标准指定了适合于一特定带宽的离散的采样。一种数字的、固定取样数的显示器(为SLM)(a digital，fixed-sample-number display)的最有效的使用要求源象素一对一地变换到显示器象素上。某些DMD也要求在一个方形栅格上的方形象素，以迫使该系统执行在所提议的US-HDTV格式下的非方形象素的内插。另外，大多数HD标准也要求使用内插硬件以重新换算数据，这一点与数字式显示的考虑无关。这个硬件执行空间的和/或时间的去压缩以减少发射所需的带宽，并且，由于这种处理能力已建立在显示器中，所以可以方便地将它用于各种标准格式之间换算。
这个数字处理单元的另一个应用是具有这样一种能力，即对已换算的数字化数据中存在的典型人工痕迹及缺陷进行校正。这种能力是一种特别重要的应用，因为换算会因算法和推算产生新的象素。简单的(且花费不多的)算法，为双线性、立方、或样条内插，是通过填充新象素来＂盲目地＂放大。这些新的象素不能增加画面中的信息，除非使用更先进的概念去分析图象中数据的内容或特征。没有这种信息，上述简单的算法及预光假设的可视数据会周期性地产生不正确的象素，如下面所给出的例子。
一般地说，这些算法是通过使原始图象中空间相邻值的加权合并进行组合来产生象素的。这一技术不关心图象内容，内插处理的方式都是一样的而与图象内容无关。例如，如果亮度被用于填充在两个象素值之间，该算法不能不去关注这二个象素有同样的强度但有完全不同的颜色。这不能引起图象中的色度误差。这种不正确的象素也导致边缘软化，相似的误差也存在于黑/亮过渡过程中。使用这样的换算技术去换算用于NTSC和HDTV显示器的视频会潜在地导致图象中视觉可察觉到的不象原始图象那样的清晰。所以对于上面所提到的在DMD装置上的NTSC和HDTV的显示来说有一个要求，即能换算图象同时保持图象的清晰度。
下面讨论涉及的术语＂边缘象素＂(edge pixel)指的是在原始图象一个边缘上的象素。下面的内容详细说明了一些公用的换算技术以及换算技术的发展以满足上述要求。
最邻近值
最邻近值是通过取同一行上的最邻近的象素作为边缘象素，并将该边缘象素的强度值重现在该象素中来完成的，但是，当该最近的象素在所述边缘的另一侧时，特别是当另一侧的强度与边缘象素所在的一侧相反时，即亮象素接着黑象素，会有一个问题。
双线性内插
双线性内插是通过计算内插点两侧原始象素值的加权之和来计算内插点处的象素值的。如果要被内插的象素X位于距象素2(P2)为＂a＂，距象素1(P1)为＂b＂的位置上，该象素的值将为
X＝aP2+bP2＂a+b＂之和为1，并且距象素越近，应给出的加权值越亮。在上述例子中，距离＂b＂更大，所以它与较近的象素P2相乘。这一技术对象素位置不敏感，并且将在穿越边缘的位置上内插。这样，在上述例子中，P1可能位于一个边缘一侧，P2在另一侧，从而导致在X处边缘软化。用双线性内插将能精确地完成强度或色彩的平滑变化，然而在边缘处却不行。该边缘的检测以及最近邻值与双线性内插之间的转换将能改善换算效果。
图2a是一个处理技术的例子，它能针对已换算成上述各种格式的数据来执行处理过程。在212中，一个计数器被初始化，该计数器用于跟踪该技术在其上得以执行的那些象素数，并察看该技术是否对在同一行或列上的象素上也加以处理。在步骤214中，已换算的象素位置被设定。这通常是根据在同一行或列中未换算的象素位置来确定已换算的象素位置。然后设定已换算象素的强度。到此结束了用于该特别的已换算的象素的处理。然后计数器增值并再检查。如果该计数器的计数等于该技术曾在其上得以执行的行或列的象素数，那么一个新的行或列开始，计数器再次初始化。如果该行或列一直未被完全处理，则下一个象素被换算。这一处理过程一直进行下去直到所有的行或列都被换算。
这样一种处理技术的实施例示于图2b。步骤212与图2a的相同。在步骤214中，通过使换算因数与计数器的计数相乘来设定位置。例如，如果该图象是输入数据大小的两倍，换算因数应为2。
图2a中的步骤216扩展成包括多个步骤。在步骤216a中，利用在步骤214中计算出的当前象素的位置来确定邻先于正被换算的象素的强度值。完成这一确定的一个方法是将该邻先的象素的强度定义为由步骤214计算出的当前象素的整数部分。如果换算是一个分数值，例如1.25，那么存在着有当前象素位置的小数部分的可能性。下个象素的强度将被定义成邻先象素的强度加1。
在步骤216b中，可以找到当前象素，领先象素及下一个象素之间的距离。其方法是取当前象素的位置且减去领先象素的强度以计算领先象素的距离。当前象素位置与下一个象素的强度相加可得到下一个象素的距离。
最后，在步骤216c中，设定当前象素的强度值。这是通过将邻先象素的源强度以领先象素的距离，以下一象素的源强度乘以下一象素的距离，然后将两个相乘的结果相加来完成的。在当前象素的位置和强度被发现之后，计数器增值，处理过程的图2a所示的那样继续。
这一技术对图象内容是敏感的。它在原始图象上执行边缘检测，并且不在原始数据中的清晰边缘内插，其结果，在原始图象中的清晰边缘在换算的图象中再现成清晰边缘，且不会导致软化(softened)或模糊(blurred)。这一技术可以与上面所列举的任一技术一起使用以提高它们的性能并提供更好的图象质量。图3a-c给出了将这种技术与双线性内插技术一起使用的例子，用于4到5垂直图象的换算。字母B、W和G指图象中黑、白及灰形部分。
图3a给出了直接的双线性内插的结果，图3b给出了上面所述讨论的技术的结果，图3c给出了将上述技术与直接双线性内插相比较的图象的例子。在图3a中，双线性内插换算仅仅在行的方向上执行，5行开始换算到6行。图3a给出了仅使用普通的双线性内插的换算。可以看出在所换算的图象中产生了假的灰色变换(G)。这将使黑和白之间其它的清晰边缘模糊。
图3b给出了使用上述技术的换算结果，即边缘敏感方法。在产生输出(已换算的)图象中的每一线的时刻，都要计算所使用的两个输入线的边缘强度(edge strength)。如果没有边缘被检测出，那么执行双线性内插。如果检测出一个边缘，那么在那些线之内不执行内插以产生相应的输出线，相应的输出线的产生是通过从最接近于它的输入线复制的值为完成的。其结果显示于图3c。
经该算法处理之后，所转换的数据被送到空间光调制器的寻址结构上。最适用于上述讨论的一种特定种类的空间光调制器是数字式微镜装置，示于图4中。 这种装置的工作细节参见美国专利U.S.5,061,049，发明名称为＂空间光调制器和方法＂。简短地说，该调制器410一般由17μ×17μ(289μ2)的镜子构成，其结构参见图4。镜子420由支柱416上的铰链悬挂在空气间隙418上方。在空气间隙的另一侧是两个电极412a和412b，它们允许镜子绕着铰链从一侧钮动到另一侧。注意，这一结果仅仅存在于扭矩梁DMD中，它是许多可使用的结构中的一种。
一个空间光调制器例如DMD的表面如图5a所示。外框510表示有效的调制区的边缘，假定为2048×1152个象素。这个调制器的整个有效面积表示描绘HD-MAC或宽的PAL信号所需的分辨率。内框说明各种格式及在调制器上有代表性的位置(未换算)。框514说明了基带MUSE或SMPTE240M格式数据的配合，它是1920×1035。框516、518和520都有同样的行数，即960。
框516有1707列，它代表了目前的HD的正常的16∶9纵横经960线图象所需的分辨率。由于960是当前NTSC格式的两部，所以人们普遍认为US-HDTV格式将有960线的简化背景兼容性(back-compatibility)。框518代表如果上述其中一个US-HD标准(解码1440列)不重新换算就被显示所得结果的图象。框520，2倍于NTSC标准，有1280列。从图中可以看出，所有这些格式将适合于该调制器的表面，但是US-HD图象在水平方向上将从其正常的1707列的尺寸压缩约15％。当观看时将能看出这种变形。US-HD是这里所示出的唯一的数字式标准，将采用上面所讨论的技术(或一个相似的技术)重新加以换算。
所以，如果提供一个处理电路以重新换算US-HD并提供一个模拟采样电路，所给出的SLM将适用于所有已说明的格式。根据数字的或模拟的MUSE解码器处理方法，一个MUST源也可能需要数字换算。MUSE解码器一般包括一个D/A滤波器和A/D再采样以改变数据的带宽满足显示所需的象素数的需要。对于数字或显示器来说，这个A/D/A及D是会产生噪声的且是昂贵的。
在US-HD的情况下(如在MUSE解码器中)，一个明显简捷的数字重新换算法似乎是将已解码成数字数据流的1440象素转换成模拟的，然后对其再采样，即每线1707象素。问题在于数字化已存在于输入信号中，已提出了某些算法以对原始的模拟波形采样，并将所采样的信号转换成模拟的并重新数字比，但是这具有在两种算法之间诱发新型干扰的危险，或者减少显示器(使用反混淆滤波器anlialising filter)可使用带宽的危险。
上述讨论假定了SLM象素是标准的方象素。在DMD中，这种矩阵中倾斜的镜子是电性连接的，通常整个地贯穿矩阵。这是因为象素的转动轴在对角线上。在对角线上实际有两组电极，它们允许镜子正确地工作。通过施加一个偏置力，第一组412a和412b使镜子激活，这个偏置力(bisa)使镜子被相互吸引。另一组414a和414b位于镜子的外端，由于所有的搁置电极(landing electrode)必须是与镜子一样加偏置的，以防止电流漏失，所以工艺难度增加以使它们沿着对角性维系在一起。
当人们考虑视频信号的性质时，这种对角线上的相互连接是有问题的，视频数据通常是在水平行上格式化的，并且每次接收一行数据，这可能使沿水平线上的镜子的相互连接方便些。这意味着水平数据格式与镜本身对角线相互连接格式不匹配，使得线的复位完全不可能。为了使一线上的电极复位，新数据必须被加在每一列中，这将引起图象的对角线的大规模复位。
但是，可以考虑不同的象素设计方案，这些设计方案提供了具有图象处理/重新换算能力的不同的比较方法，这将使多图象标准应用到不同的SKM设计上成为可能。如果象素形状是六角形的，支住位于调制器面的＂侧道＂(sideways)上，电极应能定位以便一个水平线的象素能自己复位。这种象素形状的例子示于图6中。
镜子610由两个铰链612a和612b支撑在支柱614a和614b上。如果在镜子顶半部的电极被激活，镜子的顶点618被下降，底点616上升，形成了一个能反射光的斜面，类似地，镜子也不可能向其它方面倾斜。由于偏转的尖端是水平的，能将所有电极放成一行，所以允许每次复位一行。
另一个优点是象素的密堆积，如图7所示。这一设计方案只需比方象素矩阵少13％的象素去填充具有给定水平线数的给定的纵横比区。一般要求2048×1152象素的所有采样方式在1774×1152象素中即能完成。 这种尺寸的减小可使用所涉及的电子系统中的存储器数目减少，于是降低了成本。另外，这也减少了表面积，使得工艺性相对于现行的步骤和制版增加。所述矩阵的尺度如图7所示得出。如果象素710那一侧是所说的1个单位，那么距离712和714是3个单位。距离716根据形成在象素710上的三角形718的几何关系来确定。该三角形由一个1个单位的一个边，六边形的较低的角的平分线(60°)及与象素710所在一侧相垂直的线构成。这个三角形为30-60-90三角形，弦长为1，则另两边长为5和3/2。因此距离716与侧5(5side)的侧边长相同，每个象素的高度即从支住720的中点到支柱722的中点为1.5个单位。
将1.5个单位乘以1152个象素就给出了矩阵高度为1728个单位。对于正常的纵横比来说，1728个单位用16∶9乘，等于3072个单位宽。返回到三角形718，它说明一个单位是3(2×3.2)象素宽，所以该矩阵为3072个单位每单位3个象素等于1774个象素。最后所得到的矩阵尺寸为1774×1152。使用六角形象素不能明显地降低每个象素的有效面积。一个方角素的有效面积为172，或289μ2。一个六角形象素的面积为282μ2。作为另一个好处，六角形象素，如象素710比方象更接近于圆形，所以有更均匀的空间频率响应范畴，这对于显示系统是有利的(REF)。
参照图5b，它示出了包含US-HD的能适用于新矩阵面的所有标准。US-HD没有明显的收缩或伸展。其它的标准将有一定的伸展，NTSC和HD-MA伸展13％，MUSE伸展8％。它们的长处是它们为模拟的标准，可以在所希望的不管什么频率上采样，以取得合适的尺寸，只需仅仅增加一个可变的频率时钟和模/数据换器。
一个其它的优点即关于原光提及的电极结构和特征。电极结构如图8a所示。阴影部分是一个象素的电极。电极810a和810b在区域812上连接在一起。这一连接是在面积812下的第一级金属(first-level metal)上实现的，或通过其它的任何已知的连接技术完成的，当它们被激活时，象素使它们向上倾斜，尖端搁置在区域72上，区域72处于与象素同样的偏置力下，区域72处于与象素同样的偏置力下。为了使该行的象素复位，这一行电极从810a到814b，从右到左穿越画面复位到零，区域812将具有所施加的复位信号，指示出每次复位一行是如何进行的。
电极结构的另一种方案如图8b所示。它与图8a极相似，不同的是电极在顶层，搁置区在下部。在这种情况下，搁置区应在电极的下面被系在在一起，其好处是用来吸引镜子的电压可以减小，这是因为用于产生静电吸引力的表面积增加了。如此构成的电极仍使每次一行复位保留这样一个长处，即这个特别的结构仍特别适合于多格式电视。从图8a和图8b中可以看出，绕着图象有一些黑色的带子，因为它们适合于空间光调制，所以它们不用于多种格式。
不论实际的象素形状如何，六角形栅格的线性接近性将使得数据处理简单化。
下面的表格对几个系统作了比较，这几个系统都是以图5所示的SLM为基础的。表中给出了每个系统的相对指标。每个系统都支持NTSC、HD-MAC、基带MUSE和US-HD格式的各种组合。根据所述的处理方法，整个系统的成本和性能将不同。表中所给出的是每个系统成本的推测。所述系统包括SLM118，数字处理单元116及调谐器/预处理器114。结论是需要US-HD的任何系统都能获得降低26％成本的效益。
