Description

不对称像差校正透镜
背景
计算设备的配置在不断增长。例如,随着台式个人计算机的出现,计算设备的使用得到了扩展。配置持续扩展并由此计算设备在日常生活中的渗透性也持续扩展,诸如从台式计算机到膝上型计算机、上网本、诸如移动电话和平板计算机之类的移动通信设备等等。
随着这些配置持续扩展,在一些情况下存在对使得设备不仅具有薄形状因子而且还具有大显示面积并且能够支持稳健的功能的越来越多的关注。例如,与触摸输入相关联的功能跨有显示能力的设备(例如,移动电话和电视机等)的范围变得越来越被需要。然而,用于启用触摸能力的常规光学组件可能不适于被具有这些新配置的显示设备使用。例如,如果在具有这些新配置的显示设备中利用常规光学组件,则这些常规光学组件可将像差引入由显示设备收集的图像。收集的图像或其包括这些像差的部分可能不适合于启用触摸能力或其他自然用户界面功能。
概述
描述了不对称像差校正透镜。在一个或多个实现中,透镜包括多个透镜元件,该多个透镜元件被配置成聚焦来自不对称成像组件的图像。多个透镜元件可包括被配置成重定向图像以使得该图像通过该透镜的光学透镜元件。此外,多个透镜元件可包括被配置成校正由不对称成像组件引起的像差的不对称元件。例如,不对称元件可被配置成用于校正图像中的离轴像差的离轴透镜元件。在一些实现中,多个透镜元件可包括一个以上的不对称元件以校正由不对称成像组件引起的像差。
在一个或多个实现中,图像由成像组件收集,该成像组件将不对称像差引入这些图像。可通过使用不对称透镜元件来补偿不对称像差的透镜将该不对称像差从图像中去除。在使用透镜将不对称像差去除后,这些图像可被传感器检测到并被转换成图像数据。此外,通过成像组件收集的图像可被显示成不包括由成像组件引入的不对称像差。
在一个或多个实现中,设备包括不对称成像组件,该不对称成像组件被配置成收集图像,但会将像差引入传输通过的图像。该设备还包括具有不对称透镜元件的透镜,该不对称透镜元件被配置成通过去除由不对称成像组件引入的像差来校正图像。该设备的成像传感器可被配置成检测经校正的图像。

详细描述
概览
如先前所描述的,计算设备可采取各种配置并被用于各种不同的使用。然而,常规地,这些配置中的一些与其他配置相比更不适合于支持一些功能。例如,一些常规的有显示能力的设备(例如,电视机)被配置成具有薄形状因子但还具有大显示面积。然而,这些较大的有显示能力的设备一般不被配置成支持一些自然用户界面(NUI)技术,诸如触摸能力。随着期望支持稳健功能跨有显示能力的设备(例如,移动设备和电视机等)的范围持续扩展,常规光学组件的限制可能约束将一些NUI技术包括于一部分这样的设备。
描述了不对称像差校正透镜。在一个或多个实现中,透镜被设计成用于与收集并聚焦图像以供传感器(例如光学传感器)检测的成像组件结合使用。具体地,该透镜被设计成去除引入到通过该成像组件的图像中的像差(诸如由不对称成像组件引入的像差)。
成像组件可利用楔形光学器件来投射和/或捕捉图像,例如它可被配置成楔形光导、无间隙楔形物等等。为了使用锲形光导或无间隙楔形物来投射图像,可使包括图像的光线指向该楔形物的厚端。进入锲形物的厚端的光线通过内部全反射朝向薄端传播,并反射离开该锲形物的表面直到达到临界角。当达到临界角时,光线从表面出现。通过这种方式,图像可经由楔形物的表面来投射。通过使图像源从显示屏后面移走,锲形光学器件可降低于图像投射相关联的深度。这进而可使得设备能够被设计成具有更薄的形状因子。
楔形光学器件还可被用于经由该楔形物的表面来捕捉对象的图像。为了经由该表面捕捉图像,可使摄像机或其他光学传感器指向该楔形物的厚端。摄像机可捕捉按与用于经由表面投射图像的那些光线相反的方向通过该楔形物的光线。具体地,进入该表面的光线朝向楔形物的厚端传播并从该厚端出现。
然而,呈楔形的光学组件(诸如,楔形光导和无间隙楔形物)相对于系统的光轴不是对称的(即它们是不对称的)。虽然这些不对称的成像元件可用于降低与显示和捕捉图像相关联的深度,但这样的组件还可将像差引入将被显示和捕捉的图像。例如,不对称成像组件可在这些图像的整个视野上产生大像差。然而,包括该像差的图像可能具有不可接受的显示质量和/或可能不适于启用一些自然用户界面(NUI)技术。
一些用于去除由不对称成像组件引入的像差的方法使用了常规透镜,其中各光学元件绕所述透镜的光轴是对称的。然而,使用常规透镜的方法(诸如使该透镜倾斜、减小该透镜的光圈尺寸、使被配置成检测图像的传感器倾斜,或这些方法的某种组合)常使得光从图像中丢失和/或像差在整个图像中被不均匀地减少。结果,常规方法可能仅适用于低分辨率应用。
与常规透镜相反,不对称像差校正透镜可被配置成包括不对称透镜元件。与常规透镜元件不同,包括不对称透镜元件的透镜可校正由不对称成像组件引起的像差而无需使该透镜倾斜,无需减小该透镜的光圈尺寸,并且无需使被配置成检测图像的传感器倾斜。结果,光可以不从图像中丢失,并且像差可在整个图像上被均匀地校正。此外,不对称像差校正透镜可允许收集高分辨率应用(诸如)的图像,诸如用于其中用户具有通过窗口彼此看见的体验的视频会议技术。
在以下讨论中,首先描述可采用本文描述的技术的示例环境。随后描述可在该示例环境以及其他环境中执行的示例过程。因此,各示例过程的执行不限于该示例环境,并且该示例环境不限于执行各示例过程。
示例环境
图1是示例实现中的可操作以采用本文描述的技术的环境100的图示。所解说的环境100包括计算设备102的示例,该计算设备102具有不对称成像组件104、透镜106和成像传感器108。
计算设备102可以按各种方式来配置。例如,计算设备102可被配置成有显示能力。有显示能力的设备配置的示例可在台式和膝上型计算机、电视机和其他显示监视器、桌面计算机、电子告示牌、移动电话、平板计算机、便携式游戏设备、音乐播放器等中找到。由此,计算设备102的范围可以从具有大量存储器和处理器资源的全资源设备到具有有限存储器和/或处理资源的低资源设备。
计算设备102的透镜106被解说为包括多个透镜元件110。此多个透镜元件110被配置成聚焦来自不对称成像组件104的图像。这些透镜元件110中的一些(诸如光学透镜元件112)可被配置成重定向图像以使得这些图像通过透镜106。此外,光学透镜元件112可被配置成对称透镜元件,该对称透镜元件绕透镜106的光轴旋转地对称。
所解说的配置还示出透镜元件110可包括不对称透镜元件114,该不对称透镜元件被配置成校正图像中由不对称成像组件104引起的像差。虽然在所解说的示例中仅示出了一个不对称透镜元件114,多个不对称透镜元件114可用于校正由不对称透镜组件104引入的像差。与对称透镜元件相反,不对称透镜元件114相对于透镜106的光轴可能不是对称的。例如,如图3所解说的,不对称透镜元件114可在与透镜106的光轴垂直的方向上移位,使得它相对于其他透镜元件是“离轴的”。
不同类型的不对称透镜元件114可被配置成校正由不对称成像组件104引起的特定像差。在一个或多个实现中,不对称成像组件104可被配置成锲形物,该锲形物在图像中产生像差,该像差从该锲形物的厚端出现。例如,该锲形物可在图像中产生严重的场弯曲和散光,该场弯曲和散光绕透镜106的光轴不对称(即,为离轴像差)。然而,不对称透镜元件114可被离轴地偏移以补偿场弯曲并由此使该弯曲变平并减少图像中绕透镜的光轴106对称的散光。因此,被配置成离轴透镜元件的不对称透镜元件114可用于校正在整个视野中的图像中的离轴像差。
在一个或多个实现中,不对称透镜元件114可被配置成自由形式透镜元件以补偿由不对称成像组件104产生的自由形式像差。也构想了不对称透镜元件114的用于补偿其他类型的像差的其他配置。
如先前所描述的,多个不对称透镜元件114可被包括在透镜106中,诸如用于补偿不同类型的像差的多个不同类型的不对称透镜元件。附加地或替换地,多个不同的不对称透镜元件可被包括在透镜106中以补偿在整个视野中出现的像差的不同部分。例如,透镜106可包括在离开透镜106的光轴的不同方向上移位的多个不对称透镜元件。
如上所述,计算设备102还被解说为包括成像传感器108。成像传感器108可被配置成检测图像,诸如使用透镜106来校正的图像。成像传感器108可被设置在计算设备102中,使得从不对称成像组件104出现的图像首先通过透镜106,并随后从透镜106出现以供成像传感器108检测。因此,由成像传感器108检测到的图像可不包括由不对称成像组件104引入的像差。
图2描绘了在示例实现200中的可操作以采用本文中描述的技术的设备组件。所解说的设备组件包括不对称成像组件202、不对称像差校正透镜204和传感器,其可分别对应于图1中的不对称成像组件104、透镜106和成像传感器108。
在所解说的示例中,不对称成像组件202被配置成锲形物。不对称成像组件202可例如被配置成无间隙锲形物。在所解说的示例中,描绘了指向非对称成像组件202的表面208的多个箭头。所解说的箭头可表示通过不对称成像组件202来收集和隧穿的图像。
不对称成像组件202可被配置成收集接触表面208的对象的图像,以及收集没接触表面208的对象的图像。在一些实现中,不对称成像组件202可被配置为对直接与表面208接触的对象进行成像的触摸表面。在其他实现中,不对称成像组件202可被配置成对与分开的触摸表面(未示出)接触的对象进行成像,该分开的触摸表面被放置在表面208附近但不接触表面208。此外,不对称成像组件202可被配置成对放置在离表面208一距离处的对象进行成像。
在任何情况下,不对称成像组件202都被配置成隧穿通过内部反射经过表面208进入锲形物的厚端的图像。在该厚端,经隧穿的图像从不对称成像组件202的出口部分出现。在所解说的示例中,描绘了指向从不对称成像组件202的厚端离开的箭头。该箭头指示经隧穿的图像正从出口部分出现。然而,如关于图1的不对称成像组件所讨论的,不对称成像组件202可在经隧穿的图像中产生像差。
继续对所解说的示例的讨论,指示图像正从不对称成像组件202的出口部分出现的箭头还指示这些图像通过透镜204的入口部分进入透镜204。虽然透镜204和不对称成像组件202在图2中未被示为接触,但这些组件可被布置成使得它们基本上彼此接触。在任何情况下,透镜和不对称成像组件202都可被布置成使得透镜204的入口部分基本上覆盖不对称成像组件202的出口部分。
在所解说的示例中,透镜204被描绘在虚线中并且包括多个光学元件。将领会,透镜204可包括与图2所示相比更多或更少的光学元件。所描绘的光学元件包括光圈210、多个透镜元件(例如,光学透镜元件212)、不对称透镜元件214和防护玻璃罩片216。透镜204的光学元件可被组合地配置成聚焦来自不对称成像元件202的图像以供传感器206检测。如以上更详细讨论的,透镜204的光学元件可被配置成去除由不对称成像组件202引入的像差。此外,透镜204的光学元件可被配置成去除像差,而无需使透镜204倾斜,无需停止光圈210(减小光圈210的尺寸),并无需使传感器206倾斜。
在图2中,描绘了在防护玻璃罩片216和传感器206之间的另一箭头。该箭头指示从透镜204出现的供传感器206检测的经校正的图像(例如,没有由不对称成像组件202引入的像差的图像)。
图3描绘了其中图2的不对称像差校正透镜被更详细地示出的示例实现300。在该示例中,解说了在不对称成像组件304和成像传感器306的各部分之间的透镜302。还相对于表示透镜302的光轴308的虚线描绘了透镜302。
透镜302除不对称透镜元件310以外的光学元件可被布置成使其以光轴308为中心。在一个或多个实现中,这些光学元件可绕光轴308旋转地对称。
然而,不对称透镜元件310可被放置成使得它相对于光轴308不对称。在所解说的示例中,不对称透镜元件310在与光轴308基本上垂直的方向(由箭头指示)上移位。通过使不对称透镜元件310移离光轴308,来自不对称成像组件304的像差可被去除。例如,使不对称透镜元件310在y方向上相对于光轴308移位10毫米可有效补偿由不对称透镜元件引起的像差。虽然在该示例中仅示出了一个不对称元件,但透镜302可包括多个不对称透镜元件。在一个或多个实施例中,这些其他不对称透镜元件可在与不对称透镜元件310的方向不同的方向上移位。
示例过程
以下讨论描述了可利用先前描述的系统和设备来实现的不对称像差校正技术。可以使用硬件、固件或软件或其组合来实现每一个过程的各方面。过程被示为一组框,它们指定由一个或多个设备执行的操作,不一定仅限于所示出的用于由相应的框执行操作的顺序。在下面讨论的某些部分,将参考图1的环境100。
图4是描绘在其中不对称像差校正透镜被用来校正由成像组件引入图像的不对称像差的示例实现中的过程400。图像是通过成像组件来收集的,该成像组件将不对称像差引入这些图像(框402)。例如,计算设备102的不对称成像组件104可收集图像以支持设备102的自然用户界面(NUI)技术。然而,不对称成像组件104可将不对称像差引入传输通过的图像。如先前所讨论的,如果该像差没有被去除,则收集的图像或其部分可能不适于启用触摸能力或其他NUI技术。
由成像组件引入的像差是使用包括不对称透镜元件的透镜来去除的(框404)。例如,透镜106可被用于去除由设备102的不对称成像组件104引入的不对称像差。在该示例中,透镜106中包括的不对称透镜元件114可对应于由不对称成像组件104引入的特定类型的像差。例如,为了去除离轴像差,可以包括被配置成离轴透镜元件的不对称透镜元件114。类似地,为了去除自由形式像差,可以包括被配置成自由形式透镜元件的不对称透镜元件114。
由传感器来检测不包括由成像组件引入的像差的图像(框406)。例如,被隧穿通过不对称成像组件104的图像可传输通过透镜106,且随后由成像传感器108来检测。这些图像可不包括由不对称成像组件104引入的像差,因为该像差在图像传输通过透镜106时被去除了。
在一个或多个实现中,检测到的图像被转换成图像数据(框408)。例如,计算设备102的一个或多个组件(未示出)可将成像传感器108检测到的图像转换成图像数据(例如,图像文件、视频文件、流传送视频等)。
一旦被转换成图像数据,检测到的图像就可被显示(框410)。例如,由成像传感器108检测到的图像可使用计算设备102的显示能力来显示。在一个或多个实现中,这些图像可经由不对称成像组件104来显示。附加地或替换地,这些图像可被传达给不同的计算设备并被不同的计算设备显示。
示例系统
图5在500概括地示出了包括示例计算设备502的示例系统,该示例计算设备表示可以实现此处描述的各个技术的一个或多个计算系统和/或设备。计算设备502可例如被配置成通过使用具有至少一个不对称透镜元件的透镜106将像差从图像中去除。透镜106可被配置成去除由不对称成像组件104引入的像差,如以上和先前所描述的。
示例计算设备502包括可结合一个或多个处理器或处理设备的处理系统504、可包括一个或多个存储器和/或存储组件508的一个或多个计算机可读介质506,以及用于输入/输出(I/O)设备的一个或多个输入/输出(I/O)接口510。计算机可读介质506和/或一个或多个I/O设备可以作为计算设备502的一部分被包括在内,或者替代地可被耦合到计算设备502。如所例示,处理系统504还可包括代表用硬件实现本文所述的过程和技术的至少一些方面的功能的一个或多个硬件元件512。虽然未示出,但是计算设备502可进一步包括将各种组件彼此耦合的系统总线或数据传输系统。系统总线可以包括不同总线结构中的任一个或其组合,诸如存储器总线或存储器控制器、外围总线、通用串行总线和/或利用各种总线体系结构中的任一种的处理器或局部总线。
处理系统504、处理器和硬件元件512不受形成它们的材料或者其中采用的处理机制的限制。例如,处理器可以由半导体和/或晶体管(例如,电子集成电路(IC))构成。在这一上下文中,处理器可执行指令可以是可电子地执行的指令。存储器/存储组件508表示与一个或多个计算机可读介质相关联的存储器/存储容量。存储器/存储组件508可包括易失性介质(如随机存取存储器(RAM))和/或非易失性介质(如只读存储器(ROM)、闪存、光盘、磁盘等等)。存储器/存储组件508可包括固定介质(例如,RAM、ROM、固定硬盘驱动器等)以及可移动介质(例如闪存驱动器、可移动硬盘驱动器、光盘等等)。
输入/输出接口510允许用户向计算设备502输入命令和信息,并且还允许使用各种输入/输出设备向用户和/或其他组件或设备呈现信息。输入设备的示例包括键盘、光标控制设备(例如,鼠标)、话筒(例如,其可被配置成接收语音输入)、扫描仪、触摸功能(例如,被配置成检测物理触摸的电容性传感器或其它传感器)、相机(例如,其可采用可见波长或诸如红外频率的不可见波长来将移动识别为手势),等等。输出设备的示例包括显示设备(例如,监视器或投影仪)、扬声器、打印机、网卡、触觉响应设备,等等。因此,计算设备502可以按照各种方式来配置以支持用户交互。
此处可以在软件、硬件元件或程序模块的一般上下文中描述各种技术。一般而言,此类模块包括执行特定任务或实现特定抽象数据类型的例程、程序、对象、元件、组件、数据结构等等。本文使用的术语“模块”、“功能”和“组件”一般表示软件、固件、硬件或其组合。本文描述的技术的各特征是平台无关的,从而意味着该技术可在具有各种处理器的各种商用计算平台上实现。
所描述的模块和技术的实现可以被存储在某种形式的计算机可读介质上或跨某种形式的计算机可读介质传输。计算机可读介质可包括可由计算设备502访问的各种介质。作为示例而非限制,计算机可读介质可包括“计算机可读存储介质”和“计算机可读信号介质”。
“计算机可读存储介质”可以指相对于仅信号传输、载波、或信号本身而言,启用对信息的持久和/或非瞬态存储的介质和/或设备。由此,计算机可读存储介质是指非信号承载介质。计算机可读存储介质包括以适合于存储如计算机可读指令、数据结构、程序模块、逻辑元件/电路、或其他数据等的方法或技术来实现的诸如易失性和非易失性、可移动和不可移动介质和/或存储设备的硬件。该计算机可读存储介质的示例包括但不限于,RAM、ROM、EEPROM、闪存或其它存储器技术、CD-ROM、数字多功能盘(DVD)或其它光存储、硬盘、磁带盒、磁带、磁盘存储或其它磁存储设备、或者可适用于存储所需信息并可由计算机访问的其它存储设备、有形介质或制品。
“计算机可读信号介质”可以指被配置为诸如经由网络向计算设备502的硬件传输指令的信号承载介质。信号介质通常用诸如载波、数据信号、或其它传输机制等已调制数据信号来体现计算机可读指令、数据结构、程序模块或其他数据。信号介质还包括任何信息传送介质。术语“已调制数据信号”是指使得以在信号中编码信息的方式来设置或改变其一个或多个特性的信号。作为示例而非限制,通信介质包括有线介质,诸如有线网络或直接线路连接,以及无线介质,诸如声学、RF、红外线和其他无线介质。
如前面所述描述的,硬件元件512和计算机可读介质506表示以硬件形式实现的模块、可编程设备逻辑和/或固定设备逻辑,其可被某些实施例采用来实现此处描述的技术的至少某些方面,诸如执行一个或多个指令。硬件可包括集成电路或片上系统、专用集成电路(ASIC)、现场可编程门阵列(FPGA)、复杂可编程逻辑器件(CPLD),和以硅或其它硬件实现的组件。在此上下文中,硬件可操作为通过指令和/或由硬件实现的逻辑来执行程序任务的处理设备,以及被用来存储用于执行的指令的硬件(例如上面描述的计算机可读存储介质)。
前面的组合也可被采用来实现在此描述的各种技术。因此,软件、硬件,或可执行模块可被实现为在某种形式的计算机可读存储介质上和/或由一个或多个硬件元件512实现的一个或多个指令和/或逻辑。计算设备502可被配置成实现对应于软件和/或硬件模块的特定指令和/或功能。因此,可作为软件由计算设备502执行的模块的实现可至少部分以硬件完成,例如,通过使用计算机可读存储介质和/或处理系统512的硬件元件504。指令和/或功能可以是一个或多个制品(例如,一个或多个计算设备502和/或处理系统504)可执行/可操作的,以实现此处描述的技术、模块,以及示例。
如在图5中进一步例示的,示例系统500使得用于当在个人计算机(PC)、电视设备和/或移动设备上运行应用时的无缝用户体验的普遍存在的环境成为可能。服务和应用在所有三个环境中基本相似地运行,以便当使用应用、玩视频游戏、看视频等时在从一个设备转换到下一设备时得到共同的用户体验。
在示例系统500中,多个设备通过中央计算设备互连。中央计算设备对于多个设备可以是本地的,或者可以位于多个设备的远程。在一个实施例中,中央计算设备可以是通过网络、因特网或其他数据通信链路连接到多个设备的一个或多个服务器计算机的云。在一个实施例中,该互连架构使得功能能够跨多个设备来递送以向多个设备的用户提供共同且无缝的体验。多个设备的每一个可具有不同的物理要求和能力,且中央计算设备使用一平台来使得为设备定制且又对所有设备共同的体验能被递送到设备。在一个实施例中,创建目标设备的类,且使体验适应于设备的通用类。设备类可由设备的物理特征、用途类型或其他共同特性来定义。
在各种实现中,计算设备502可采取各种各样不同的配置,诸如用于计算机514、移动设备516和电视机518用途。这些配置中的每一个包括可具有在总体上有不同的构造和能力的设备,并且因而计算设备502可根据不同的设备类中的一个或多个来配置。例如,计算设备502可被实现为计算机514类的设备,该类包括个人计算机、台式计算机、多屏幕计算机、膝上型计算机、上网本等。
