Description

用于控制立体眼镜遮光器的系统和方法 A system and method for controlling stereo glasses shutters

技术领域 FIELD

[0001] 本发明涉及视频显示器,且更明确地说,涉及利用立体遮光器眼镜来观看立体视频和图形图像。 [0001] The present invention relates to video displays, and more particularly, relates to the use of shutter glasses to view three-dimensional stereoscopic video and graphic images.

背景技术 Background technique

[0002] 装备各种显示器装置以便进行单维(mono)和立体观看两者。 [0002] The display device for various equipment unidimensional (Mono) and a perspective view both. 与单维观看不同,立体观看涉及显示人的左眼和右眼的独立内容。 With different one-dimensional viewing, the stereoscopic viewing content to a display independent human left and right eyes. 具体地说,此类立体观看需要向人的左眼和右眼呈现独立图像。 Specifically, such a stereoscopic viewing image needs to be rendered independent to a human left and right eyes. 在ー种特定类型的立体观看(即,时序式立体观看)中,以交替方式呈现此类左图像和右图像。 In stereoscopic viewing ー species specific type (i.e., the timing of formula stereoscopic viewing), the presentation of such an alternating manner left and right images. 为了确保适当的立体观看体验,也通常使用交替遮光器眼镜,其使得在恰当时间左眼看到左图像且右眼看到右图像。 To ensure proper stereoscopic viewing experience is also commonly used alternately shutter glasses so that the left eye and the left eye image at the appropriate time to see the right image.

[0003] 过去,时序式立体观看已在CRT和相关显示器[例如,高帧速率(DLP)投影仪等]上工作良好。 Works well on [0003] In the past, the timing of formula stereoscopic viewing is [e.g., high frame rate (DLP) projector, etc.] and the associated CRT display. 然而,由于若干问题,时序式立体观看在液晶显示器(IXD)(不管是平板还是投影仪形式)上还没有展现前景。 However, due to several problems, the timing of formula stereoscopic viewing on a liquid crystal display (IXD) (whether in the form of a tablet or projector) also did not show the foreground. 举例来说,LCD环境中的像素的慢响应时间使得右视图中存在左图像的“叠影”,且反之亦然。 For example, the slow response time of the LCD pixels in the environment so that there is a right side view of the left image "ghost image", and vice versa. 此外,遺憾的是,IXD更新过程的本质导致可完整呈现右图像和左图像的仅较短的时间周期,如现在将详细描述。 Also, unfortunately, the nature of IXD update process can lead to a complete view of the right and left images only a short period of time, as will now be described in detail.

[0004] 图IA说明在利用LCD来尝试立体观看的情况下将存在的假设缺点。 [0004] FIG IA described using an LCD attempt to assume a case where stereoscopic viewing of drawbacks would be present. 如本假设实例中所展示,IXD将通过电缆10 (例如,数字视频接ロ(DVI)或视频图形阵列(VGA)电缆)以光栅扫描次序(即,从上到下、逐行、从左到右等)接收像素。 As shown in this hypothetical example, IXD through cable 10 (e.g., a digital video connection ro (DVI) or a video graphics array (VGA) cable) raster scan order (i.e., from top to bottom, row by row, from left to right, etc.) the received pixels. 首先通过电缆10发送希望由左眼观看的第一左图像LI。 First, a first desired by the left eye image LI viewed by transmission cable 10. 此后,存在被称为垂直消隐间隔VBI的传输中止。 Thereafter, the presence is called the vertical blanking interval VBI of aborted transmissions. 接下来,发送希望用于右眼的第一右图像R1,等。 Next, a first transmission intended for a right eye image R1, and the like.

[0005] 与CRT和其它相关显示器不同,IXD像素具有个别电容性存储元件,所述电容性存储元件使得每ー像素保留其顔色和強度直到LCD驱动器相关电子元件对其进行更新为止,所述IXD驱动器相关电子元件以光栅次序寻址像素。 [0005] with different CRT displays and other related, IXD individual pixels having capacitive storage element, such that the capacitive storage element of each pixel ー retains its color and intensity until the LCD driver until the electronic component to update the IXD drive electronic component addressed pixel in raster order. 因此,在时间Tl,当已发送第一右图像Rl的部分吋,从IXD屏幕发出的实际图像包含在底部的第一左图像LI的“未覆写”(例如,红色)部分和第一右图像Rl的新写入(例如,緑色)部分。 Thus, at time Tl, when the transmission section has a first right image Rl inches, the actual image emanating from the screen contains IXD "not override" (e.g., red) and a first portion of a first right-left image at the bottom of the LI Rl newly written image (e.g., green) part. 此外,在T2,且实际上整个垂直消隐间隔VBI在时间T2开始,显示仅包含第一右图像R1。 Further, in T2, and indeed the entire vertical blanking interval VBI starting at time T2, only the display comprises a first right image R1. 在时间T3,已由第二左图像L2以所展示方式部分地覆写第一右图像Rl。 At time T3, by the second left image L2 in a manner shown partially overwriting the first right image Rl. 为此,如果向左眼或右眼展示时间Tl和T3的显示内容,那么此眼将不幸地接收到并不希望用于此眼的至少部分内容。 For this reason, if the display content presentation time Tl and T3 to left or right eye, then the eye will unfortunately not intended for receiving at least a portion of this eye.

[0006] 如早先所提及,通常使用装备有右眼遮光器和左眼遮光器的立体眼镜来确保在立体观看期间适当眼睛观看到恰当图像。 [0006] As mentioned earlier, the use of stereo glasses typically have the right eye shutter and a left eye shutter of the equipment to ensure that the proper eye stereoscopic viewing during the watch to a proper image. 如所展示,在本假设实例中,在显示第一左图像LI之后,左眼遮光器控制20将左遮光器切換到打开方位(在此期间右遮光器維持在关闭方位中)。 As shown, in this hypothetical example, the left image LI displayed after the first, the left-eye shutter control 20 switches to the left shutter open orientation (during which the right shutter is maintained in the closed orientation). 类似地,在显示第一右图像Rl之后,右眼遮光器控制30将右遮光器切換到打开方位(此时左遮光器转换到关闭方位且维持在关闭方位中)。 Likewise, after displaying a first right image Rl, right eye shutter control unit 30 switches the shutter to an open orientation the right (left shutter case converted to a closed position and maintained in the closed orientation).

[0007] 此外,遗憾的是,每一眼睛在相关联的遮光器处于打开方位的持续时间的相当大部分期间接收到并不希望用于此眼睛的至少部分内容,从而导致不令人满意的立体观看。 [0007] In addition, unfortunately, it is at least part of each eye receives a significant portion open during the duration of the orientation does not want to be used for this in the eyes of the associated shutter, resulting in unsatisfactory stereoscopic viewing. 因此,需要克服与现有技术相关的这些和/或其它问题。 Therefore, a need to overcome these and / or other problems associated with the prior art. 、发明内容 , Summary

[0008] 提供用于控制立体眼镜遮光器的系统、方法和计算机程序产品。 System [0008] provided for controlling the stereo glasses shutters, methods and computer program products. 在使用中,立体眼镜的右眼遮光器经控制以在关闭方位与打开方位之间切換。 In use, the right-eye shutter of the stereoscopic glasses controlled to switch between a closed orientation and an open orientation. 此外,立体眼镜的左眼遮光器经控制以也在关闭方位与打开方位之间切換。 In addition, the stereoscopic glasses, the left eye shutter are controlled to switch between a closed orientation and open orientations. 在使用中,立体眼镜的右眼遮光器和左眼遮光器可经控制以使得右眼遮光器和左眼遮光器在预定时间量期间同时保持在关闭方位中。 In use, the stereoscopic glasses right eye shutter and the left eye shutter may be controlled so that the right eye shutter and a left eye shutter simultaneously remain in the closed position during a predetermined amount of time.

[0028] 图2展示根据ー个实施例的用于提高在利用立体眼镜观看显示内容时的观看体验的示范性时序200。 [0028] FIG. 2 shows an embodiment ー for improving the viewing experience when viewing the display using the stereoscopic glasses exemplary timing 200. 作为选择,可在图IB的计算机系统100的情境下实施本时序200。 Alternatively, this sequence may be implemented in the context of FIG. IB 200 of computer system 100. 然而,当然可在任何所要环境中使用时序200。 However, of course be used in any desired sequence 200 environment. 此外,在以下描述期间应用上述定义。 Further, the above definitions apply during the following description.

[0029] 如所展示,显示器(例如,图I的显示器108等)通过通信媒体201 (例如,数字视频接ロ(DVI)或视频图形阵列(VGA)电缆,或任何其它能够传送显示内容的相关媒体)接收显示内容。 [0029] As shown, a display (e.g., Figure I a display 108, etc.) via a communication medium 201 (e.g., a digital video connection ro (DVI) or a video graphics array (VGA) cable, or any other capable of transmitting display related content media) to receive the contents. 在本描述的情境下,此类显示内容可包含像素相关信息、(多个)图像和/或处理的任何阶段处的能够显示的任何其它内容或其组分。 In the context of the present description, such display content may comprise information about the pixel, image (s) and / or at any stage of the process can be displayed or contents of any other components. 在图2中,展示为首先通过通信媒体201发送希望仅由左眼观看的第一左图像LI。 In FIG. 2, shown as a first medium 201 through the communication desired by the first left eye image LI is only viewed. 此后,存在被称为垂直消隐间隔VBI的传输中止。 Thereafter, the presence is called the vertical blanking interval VBI of aborted transmissions. 接下来,接着发送希望仅用于右眼的第一右图像Rl等。 Subsequently, desirable only then transmits a first right-eye image Rl, and the like.

[0030] 如进ー步所展示,可独立地控制立体眼镜(例如,立体眼镜111等)的右眼遮光器和左眼遮光器。 [0030] As further shown ー feed, may be controlled independently stereo glasses (e.g., stereo glasses 111, etc.) of the right eye shutter and a left eye shutter. 在一个实施例中,此通过利用用于控制右眼遮光器的右眼控制信号206和用于控制左眼遮光器的左控制信号208来完成。 In one embodiment, the right eye, the right eye by using the shutter for controlling the control signal 206 for controlling a left eye and a shutter control signal 208 to complete.

[0031] 具体地说,立体眼镜的左眼遮光器可经控制以使得左眼遮光器至少在第一组垂直消隐间隔210的持续时间期间处于打开方位中,所述第一组垂直消隐间隔210跟在接收到希望用于左眼的显示内容之后。 [0031] Specifically, the left eye shutter of the stereo glasses may be controlled such that the left eye shutter least a first set of vertical blanking in the open position during the duration of the interval 210, the first set of vertical blanking after receiving the 210 with the desired spacing for displaying the contents of the left eye. 以类似方式,立体眼镜的右眼遮光器可经控制以使得右眼遮光器至少在第二组垂直消隐间隔213的持续时间期间处于打开方位中,所述第二组垂直消隐间隔213跟在接收到希望用于右眼的显示内容之后。 In a similar manner, the right eye shutter stereo glasses may be controlled such that the right-eye shutter at least a second set of vertical blanking in the open position during the duration of the interval 213, the second set of vertical blanking interval 213 with after receiving the desired display content for the right eye. 如所展示,第一组垂直消隐间隔210与第二组垂直消隐间隔213交替,且所述两者在从内容源接收到右眼内容或左眼内容的周期之间发生。 As shown, a first set of vertical blanking interval 210 and the second set of vertical blanking intervals 213 alternately, and both occur between the received content from the content source to the right eye or the left eye content cycle.

[0032] 在其它实施例中(例如,特定地说,在无线立体眼镜的状况下等),可利用多个信号(例如,代码等)来控制立体眼镜的右眼遮光器和左眼遮光器。 [0032] In other embodiments (e.g., particular to say, in the case of a wireless stereo glasses, etc.), may utilize a plurality of signals (e.g., code, etc.) to control the stereo glasses right eye shutter and the left-eye shutter . 在此类实施例中,此类信号中的一者可经具体地分配以使右眼遮光器和左眼遮光器同时转变到关闭方位且保持在关闭方位中。 In such an embodiment, one of these signals may be specifically distributed so that the right eye shutter and a left eye shutter transition to a closed position and simultaneously held in the closed orientation. 当然,可使用独立信号来仅关闭右眼遮光器、左眼遮光器等。 Of course, independent signals can be used to turn off only the right-eye shutter, the left eye shutter and the like.

[0033] 为此,立体眼镜的右眼遮光器和左眼遮光器可经控制以使得右眼遮光器和左眼遮光器在预定时间量209期间同时保持在关闭方位中。 [0033] To this end, the stereoscopic glasses right eye shutter and the left eye shutter may be controlled so that the right eye shutter and a left eye shutter kept in the closed position 209 during the same time a predetermined amount of time. 如所展示,此类预定时间量209代表第一右图像Rl已被第一左图像LI部分地覆写的时间。 As shown, such a predetermined amount of time 209 representing the first image of the first left right image Rl LI has been partially overwritten time. 因此,通过确保立体眼镜的右眼遮光器和左眼遮光器两者在此类时间期间同时保持在关闭方位中,防止了右眼内容达到左眼且防止了左眼内容达到右眼。 Thus, by ensuring both the right eye shutter of the stereoscopic glasses and the left-eye shutter during such time while held in the closed position, the content is prevented to reach the right-eye and left-eye contents reach the left eye is prevented.

[0034] 在图2中所说明的实施例中,立体眼镜的左眼遮光器可经控制以使得左眼遮光器仅在第一组垂直消隐间隔210的持续时间期间(即,在仅左眼内容被显示时等)处于打开方位中。 [0034] In the embodiment illustrated in FIG 2, the stereoscopic glasses, the left eye shutter may be controlled such that the left eye shutter during the duration of the interval 210 only in the first set of vertical blanking interval (i.e., only the left eye contents are displayed, etc.) in an open orientation. 此外,立体眼镜的右眼遮光器可经控制以使得右眼遮光器仅在第二组垂直消隐间隔213的持续时间期间(即,在仅右眼内容被显示时等)处于打开方位中。 In addition, the stereoscopic glasses right eye shutter may be controlled such that only the right-eye shutter during a second set of vertical blanking interval duration 213 (i.e., when the content is displayed only the right eye, etc.) in an open orientation. 因此,此类预定时间量209代表第一右图像Rl已被第一左图像LI部分地覆写的整个时间帧等。 Accordingly, such a predetermined amount of time 209 is representative of a first right image Rl entire time frame is a first left image LI and the like partially overwritten.

[0035] 然而,在其它实施例中,立体眼镜的右眼遮光器和左眼遮光器可经控制以使得遮光器每ー者在可调时间周期期间(其中减小了预定时间量209)保持在打开方位中,以准许额外光通过每ー各自遮光器。 [0035] However, in other embodiments, the stereoscopic glasses right eye shutter and the left eye shutter may be controlled so that the shutter during each ー by an adjustable period of time (reduced by a predetermined amount of time in which 209) held in the open position in order to permit additional light through each ー their shutters. 參见(例如)周期210。 See, (e.g.) 210 cycles. 为此,用户的眼睛可经受较多光,由此提闻图像的感知売度。 For this reason, the user's eye may be subjected to more light, thereby providing bai perceived smell of the image. [0036] 换句话说,立体眼镜的左眼遮光器可经控制以使得左眼遮光器在超出第一组垂直消隐间隔210的持续时间的周期期间处于打开方位中。 [0036] In other words, the left eye shutter of the stereo glasses may be controlled such that the left eye shutter is in an open position during the period exceeds a first set of vertical blanking interval duration 210. 类似地,立体眼镜的右眼遮光器可经控制以使得右眼遮光器在超出第二组垂直消隐间隔213的持续时间的周期期间处于打开方位中。 Similarly, the right eye shutter stereo glasses may be controlled such that the right-eye shutter during a period exceeds a second set of vertical blanking interval duration 213 is in an open orientation. 当然,与此类选择相关联的ー个权衡涉及增加其中每一眼睛接收并不希望用于此眼睛的至少部分内容的持续时间。 Of course, such a selection is associated with a weigh ー relates to increasing the duration of each eye which is not intended for receiving at least this part of the eye. 具体地说,可能会在右眼遮光器处于打开方位中时显示左眼内容的至少一部分,且反之亦然。 Specifically, at least a portion of the display may be left open orientation content when the right eye shutter, and vice versa.

[0037] 如參看图IB所陈述,可増加与所接收的显示内容相关联的垂直消隐间隔VBI的持续时间以用于提高在利用立体眼镜观看显示内容时的观看体验。 [0037] As set forth with reference to FIG. IB, it can be associated with the display to increase in the received content associated with the vertical blanking interval duration of the VBI for enhancing the viewing experience when viewing the display using the stereoscopic glasses. 通过增加垂直消隐间隔VBI的持续时间,増加了每一眼睛接收到完全希望用于此眼睛的内容的时间周期,从而导致显示器上内容的提高的立体观看。 By increasing the vertical blanking interval VBI duration, to increase in the period of time desired for each eye receives a full contents of this eye, resulting in an increased content of the stereoscopic viewing on the display.

[0038] 请注意,垂直消隐间隔VBI可以任何所要方式増加。 [0038] Note that the vertical blanking interval VBI may be in any desired manner to increase in. 举例来说,在内容源将数据发送到显示器之前,可咨询恰当的显示时序规格。 For example, before the content source to send data to the display, consult appropriate display timing specifications. 此可通过使用通信媒体201且使用任何所要接ロ[例如,扩展的显示数据通道/扩展的显示识别数据(E-DDC/EDID)、视频电子标准协会(VESA)接ロ等]来完成。 This may be by using a communication medium 201 and using any desired contact ro [e.g., extended display data channel / extended display identification data (E-DDC / EDID), Video Electronics Standards Association (VESA) connected ro the like] to complete. 为此,内容源可选择许多已建立/标准时序和/或定制时序的一者来发送内容,其中此类时序允许垂直消隐间隔VBI増大。 To this end, a number of content sources selectively established / standard sequence and / or timing of customized content to transmit one, where such timing allows the enlargement of the vertical blanking interval VBI large. 可进ー步由立体眼镜的制造商、使用配置文件来驱动图像的图形处理器等来提供/維持此类时序。 You can enter further ー stereo glasses by the manufacturer, using the configuration file to drive the image graphic processors to provide / maintain such a timing. 关于各种示范性技术的更多信息将在參考后图期间详细陈述,其中可具体地使用所述各种示范性技术来以此方式増加垂直消隐间隔VBI的持续时间。 For more information on the various exemplary technique will be set forth in detail in FIG period after the reference, in which in particular the use of a variety of techniques in this exemplary embodiment to increase in the duration of the vertical blanking interval VBI's.

[0039] 图3展示根据ー个实施例的用于增加垂直消隐间隔以用于提高在利用立体眼镜观看显示内容时的观看体验的方法300。 [0039] FIG. 3 shows one embodiment for the embodiment according ー vertical blanking interval is increased for enhancing the stereoscopic viewing eyeglasses use experience when viewing the display content 300 method. 作为ー选择,本方法300可在图IB的计算机系统100和/或图2的时序200的情境下实施。 As ー Alternatively, the method 300 may be implemented in the context of sequence 200 of FIG. IB computer system 100 and / or Figure 2. 然而,当然可在任何所要环境中实施方法300。 However, the method 300 may of course be implemented in any desired environment. 此外,以下描述期间应用上文中所引入的定义。 Further, the above definitions apply introduced during the following description.

[0040] 如所展示,以自然分辨率驱动显示器(例如,图I的显示器108等)。 [0040] As shown, the drive native resolution display (e.g., display 108 in FIG. I, etc.). 參见操作303。 See operation 303. 此类自然分辨率可指显示器经设计以不转换地显示内容的分辨率。 Such native resolution of the display means may be designed to display the content without converting the resolution. 自然分辨率通常是基于显示器中的实际单元数目。 NATURAL resolution is often based on the actual number of cells in the display.

[0041] 接下来,通过利用像素时钟来增加将像素发送到显示器的速率。 [0041] Next, by using the pixel clock rate to increase the pixels are sent to the display. 具体地说,在ー个实施例中,可出于显示目的而通过使用可能的最高像素时钟来传输像素。 Specifically, in one embodiment ー embodiment, for display purposes may be transmitted using the highest possible pixel by pixel clock. 參见操作304。 See operation 304. 在一个示范性实施例中,此类最大像素时钟可包含标准规定连接电缆所支持的最大像素时钟(例如,对于单链路DVI电缆的165 Mpix/s,对于双链路DVI电缆的330 Mpix/s等)。 In one exemplary embodiment, such a pixel clock may include a pixel clock standard connection cable supports (e.g., for a single link of the DVI cable 165 Mpix / s, for the dual-link DVI cable 330 Mpix / s or the like). 在另一实施例中,前述可能的最高像素时钟可包含相关EDID信息中的由显示器所指示的像素时钟极限。 In another embodiment, the highest possible pixel clock may include a pixel clock indicated by the display limit related EDID information. 此类极限可与DVI电缆时钟极限相同或低于DVI电缆时钟极限。 Such limits may be the same or less than the limit of the clock DVI cable DVI cable clock limit.

[0042] 此外,减小与显示相关联的水平消隐间隔,如操作306中所指示。 [0042] In addition, reducing the level associated with the display blanking interval, as indicated in operation 306. 在本描述的情境下,水平消隐间隔是指连续线的处理从右返回到左的间隔。 In the context of the present description, the horizontal blanking interval is a continuous processing line from right to left return interval. 在一个实施例中,可将水平消隐间隔选择为尽可能小。 In one embodiment, the horizontal blanking interval may be selected to be as small as possible. 通过以前述方式最大化像素时钟且最小化水平消隐间隔,可最大化垂直消隐间隔持续时间。 By maximizing the pixel clock in the foregoing manner and minimizes the horizontal blanking interval, maximize the duration of the vertical blanking interval. 将在描述稍后陈述的实例期间明白完成此目标的方式。 It will be apparent to accomplish this goal during the example described later stated way.

[0043] 用于增加垂直消隐间隔(除増加像素时钟等以外)的替代技术可涉及降低显示器刷新速率。 [0043] for increasing the vertical blanking interval of alternative technologies (except to increase in the pixel clock, etc.) may involve reducing the display refresh rate. 举例来说,在一个说明性实施例中,可在85 Hz下以19%的垂直消隐间隔使用设计用于100 Hz的具有低垂直消隐间隔的显示器。 For example, in one illustrative embodiment, it may be 85 Hz to 19% of the vertical blanking interval of the monitor designed for use with a low of 100 Hz vertical blanking interval.

[0044] 在各种实施例中,显示器可特定装备有多个额外时序以用于增加垂直消隐间隔的持续时间。 [0044] In various embodiments, the display may be equipped with a plurality of additional specific timing for increasing the duration of the vertical blanking interval. 虽然显不器可以多种方式中的任何一者装备有额外时序,但在ー个实施例中,此可通过将额外时序包含在存储于显示器的存储器中的软件中来完成。 Although not significant in many ways can be any one provided with an additional sequence, in one embodiment ー embodiment, this additional sequence can be accomplished in a memory contained in the memory of the display software. 在使用中,此类额外时序可各自适用于减小与显示相关联的水平消隐间隔和/或增加将像素发送到显示器的速率。 In use, each such additional sequence can be adapted to reduce the level associated with the display blanking interval and / or increase the rate of transmission to the display pixel.

[0045] 表I说明可以前述方式添加的ー个示范性时序。 [0045] Table I illustrates one exemplary timing ー foregoing embodiment may be added. 当然,此类时序仅出于说明性目的而陈述且不应解释为以任何方式限制。 Of course, such statements and the timing only and should not be construed as limiting in any way for illustrative purposes. 举例来说,在VGA环境中,可针与显示器相关联地更新此表,而在DVI环境中,此类改变可能并非必要。 For example, in a VGA environment, the needle may be associated with a display update this table, and in the DVI environment, such changes may not be necessary.

[0048] 请注意,在IXD、DLP型显示器等的情境下,上述水平消隐间隔较不重要,由此提供了牺牲水平消隐间隔来延长垂直消隐间隔的机会。 [0048] Note that, in the context IXD, DLP type display, etc., the less important the horizontal blanking interval, thereby providing the opportunity to extend the horizontal blanking interval sacrificial vertical blanking interval. 明确地说,在CRT型显示器中,此类水平消隐通常经增大(例如,在15%到25%的范围内等)以允许重新追踪到特定扫描线的开始处。 In particular, in the CRT-type display, such increase is typically blanking level (e.g., like in the range of 15% to 25%) to permit the track to re-start at a particular scan line. 举例来说,CRT型显示器可显示第一行的X个像素,此后可使用水平消隐间隔来向显示器提供重新追踪到扫描线的开始的时间以使得可显示另一行的X个像素,依此类推。 For example, CRT type display may display pixels of the first row of X, may thereafter be used to provide a horizontal blanking interval of time to re-start track scanning lines can be displayed to the display so that the pixels of another row X, so analogy.

[0049] 等式#1说明水平消隐间隔与垂直消隐间隔之间的相互关系。 [0049] Equation # 1 illustrates the horizontal blanking interval and the relationship between the vertical blanking interval.

[0050]等式 #1 [0050] Equation # 1

[0051] fpix = (pixels_X-direction + HBI) * (pixels_Y_direction + VBI) * fv [0051] fpix = (pixels_X-direction + HBI) * (pixels_Y_direction + VBI) * fv

[0052] 其中 [0052] in which

[0053] fpix =像素速率 [0053] fpix = pixel rate

[0054] HBI =水平消隐间隔中的像素数目 [0054] HBI = number of pixels in the horizontal blanking interval

[0055] pixels_X-direction = X方向上的像素数目(对于预定分辨率) [0055] pixels_X-direction = the number of (for predetermined resolution) pixels in the X direction

[0056] VBI =垂直消隐间隔中的关联像素数目 [0056] VBI = number of associated pixels in the vertical blanking interval

[0057] pixels_Y_direction = Y方向上的像素数目(对于预定分辨率) [0057] pixels_Y_direction = number of pixels in the Y direction (for a predetermined resolution)

[0058] fv =刷新速率 [0058] fv = refresh rate

[0059] 如所展示,可牺牲水平消隐间隔以用于延长垂直消隐间隔(明确地说,在IXD、DLP型显示器等的情况下)而未必影响像素速率和刷新速率。 [0059] As shown, the horizontal blanking interval to be sacrificed for extending the vertical blanking interval (specifically, in the case IXD, DLP type display, etc.) not necessarily affect the refresh rate and pixel rate.

[0060] 因此,在一个实施例中,表I的前述时序可提供替代的1280X1024 75Hz立体相容时序规格,所述替代规格可与现存VESA 1280X1024 75Hz时序规格共存。 [0060] Thus, in one embodiment, the sequence of Table I may provide an alternative perspective 1280X1024 75Hz compatible timing specifications, the specifications can coexist with the existing alternate VESA 1280X1024 75Hz timing specifications. 在此类示范性实施例中,现存1280X 1024 75Hz VESA时序将可用时间的24. 2%用于水平消隐且将3. 9%用于垂直消隐,而立体相容时序将接近可用时间的27%用于垂直消隐且将小于4%用于水平消隐。 In such an exemplary embodiment, the existing 1280X 1024 75Hz VESA timing will be available for 24.2% of the horizontal blanking period and the vertical blanking for 3.9%, and a timing perspective compatible proximity available time 27% for the vertical blanking interval and the horizontal blanking for less than 4%.

[0061] 图4展示根据另ー实施例的用于增加垂直消隐间隔以用于提高在利用立体眼镜观看显示内容时的观看体验的方法400。 [0061] FIG. 4 shows a method according to another embodiment of the embodiment ー viewing experience when increasing the vertical blanking interval for use in improving the stereoscopic glasses 400 displays the content. 作为ー选择,可在图IB的计算机系统100和/或图2的时序200的情境下进行本方法400。 As ー selection, the process 400 may be performed in the context of sequence 200 of FIG. IB computer system 100 and / or Figure 2. 然而,当然可在任何所要环境中实施方法400。 However, of course, the method 400 may be implemented in any desired environment. 此外,在以下描述期间应用上文中所引入的定义。 Furthermore, the application definition introduced above, during the following description.

[0062] 如所展示,在使用期间以较低分辨率设置显示器(例如,图I的显示器108等)。 [0062] As shown, during use, is provided at a lower resolution display (e.g., display 108 in FIG. I, etc.). 參见操作402。 See operation 402. 此外,可以预定速度运行显示器以用于延长垂直消隐间隔。 Further, it is possible to display a predetermined speed operation for extending the vertical blanking interval. 注意操作404。 Note operation 404. 以下陈述此类技术的实例。 The following statements are examples of such technologies.

[0063] 具体地说,在一个可选实施例中,可提供设计用于1600x1200分辨率但以较低分辨率(例如,1024x768)使用的显示器。 [0063] Specifically, in an alternative embodiment, may be designed to provide a resolution of 1600x1200 but at a lower resolution (e.g., 1024x768) displays. 如果此类显示器在60 Hz下支持1600x1200分辨率(根据VESA标准),那么可能能够达到162 Mpix/s (在任何分辨率的情况下)。 If such support 1600x1200 resolution displays at 60 Hz (according to the VESA standard), it may be possible to reach 162 Mpix / s (in the case of any resolution). 因此,通过以162 MHz像素时钟向显示器发送1024*768个像素,可在5. 33毫秒(1144*768*6. 173e_9)内发送整个图像(假设100像素水平消隐)。 Thus, by transmitting the 1024 x 768 pixels to 162 MHz to the display pixel clock, the entire image may be sent (assuming 100 pixels in a horizontal blanking) within 5.33 ms (1144 * 768 * 6. 173e_9). 由于每16. 66毫秒接收到60 Hz的图像,因此垂直消隐间隔可延长到11. 33毫秒(16. 66-5. 33)。 Since each received 16.66 milliseconds to 60 Hz image, thus the vertical blanking interval may be extended to 11.33 msec (16. 66-5. 33). 为此,一副立体眼镜的每一遮光器(例如,图I的立体眼镜111等)可在每33. 33毫秒期间有11. 33毫秒保持在打开方位,由此提供34%的工作循环(在理论最大值50%的范围外)。 For this purpose, a three-dimensional shutter glasses for each (e.g., 111 in FIG. I is a perspective glasses, etc.) may have 34% of 11.33 milliseconds duty cycle held in the open position, thereby providing during each 33.33 msec ( outside the range of 50% of the theoretical maximum).

[0064] 在一个实施例中,可视情况通过利用耦合到显示器的控制器(例如,图I的立体控制器119等)来提供图3到图4的前述功能性。 [0064] In one embodiment, optionally through the use of functional coupled to the display controller (e.g., controller 119 in FIG. I is a perspective, etc.) to provide 3 to 4. 在本实施例的情境下,此类控制器可用于分接馈送到显示器的电缆中的信号以检索用于眼镜(例如,图I的立体眼镜111等)的触发信息。 In the context of the present embodiment, the signal cable can be used to tap feeding such a display controller for spectacles to retrieve (e.g., stereo glasses 111 of FIG. I, etc.) trigger information. 此类触发信息可从电缆中的垂直同步、以及识别与内容相关联的信息(例如,白线代码等)的左/右眼遮光器或由软件提供的控制信号(例如,DDC信号等)中得到。 Such information may trigger the vertical sync cable, and identifying information associated with the content (e.g., white line code, etc.) of the left / right eye shutter or a control signal provided by the software (e.g., the DDC signal, etc.) get.

[0065] 在另ー实施例中,可通过中断两个I2C·接ロ线来提供图3的方法300和图4的方法400,所述I2C⑩接ロ线通常运载EDID标准信息。 [0065] In another embodiment the method ー, FIG 3 may be provided by interrupting two I2C · ro connection line 300 and the method 400 of FIG. 4 embodiment, the wire generally carries I2C⑩ then ro EDID standard information. 在其中控制器呈微控制器形式的实施例中,此类硬件可读取原始显示器EDID信息且将经修改的EDID信息呈现给相关联的计算机系统。 In embodiments where the controller was in the form of a microcontroller, such hardware may display the EDID information read the original and the modified EDID information is presented to the associated computer system. 在此类实施例中,使用EDID信息来计算时序设置的驱动器未必需要修改。 In such embodiments, the EDID information used to calculate the drive does not necessarily need to modify the timing settings.

[0066] 图5展示根据另ー实施例的用于在利用立体眼镜和IXD或类似物观看显示内容时使用的示范性时序500。 [0066] FIG. 5 shows an exemplary timing used when using IXD stereoscopic glasses and viewing the display, or the like used for another embodiment ー 500. 作为ー选择,可在图IB的计算机系统100和/或图2的时序200的情境下进行本时序500。 As ー selection may be made in the context of this timing sequence 500 of FIG. IB 200 computer system 100 and / or Figure 2. 然而,当然可在任何所要环境中使用时序500。 However, of course, be used in any desired sequence 500 environment.

[0067] 在本实施例中,在操作502中发送到显示器的显示内容又可以操作504中所展示的方式接收并缓沖。 [0067] In the present embodiment, transmitted to the display in the display contents and operation 502 may operate in the illustrated embodiment 504 receives and buffers. 作为ー选择,可通过利用驻留在显示器中或在任何其它相关位置中的缓冲器存储器(例如,DRAM等)来进行此类缓沖。 As ー selection, can be performed by using such a buffer or a buffer residing in the display memory (eg, DRAM, etc.) in any other related position.

[0068] 一旦在操作504中接收并缓冲用于特定眼睛的显示内容,便可将其从缓冲器发送到显示器,如操作504中所进ー步指示。 [0068] Upon receiving the contents of the display buffer and for a particular eye in operation 504, it can be transmitted from the buffer to the display, as in the operation 504 into ー sync indication. 为此,显示器可描绘当前正从缓冲器发送来的特定显示内容。 For this purpose, the display may depict a particular display content currently being transmitted from the buffers. 注意操作506。 Note operation 506. 应注意,在已发送并描绘用于特定眼睛的显示内容之后,可以所展示方式保持此类显示内容。 It is noted that, after the display content has been sent and is depicted for a particular eye, the illustrated embodiment may be held such display contents.

[0069] 通过这个设计,一副立体眼镜(例如,图I的立体眼镜111等)的左眼遮光器和右眼遮光器可在对应显示器内容正被保持的时间周期期间打开。 [0069] By this design, a stereo glasses (e.g., stereo glasses 111 of FIG. I, etc.) of the left-eye shutter and the right eye shutter may be opened during a time period corresponding to the display content being retained. 分别注意操作508和510。 Note that operation 508 and 510, respectively. 通过以前述方式在操作504中对显示内容进行缓冲,可获得显示内容穿过电缆到达缓冲器所需要的任何冗长时间,因此将像素时钟保持为低。 By the way buffering the contents displayed in operation 504, the display content can be obtained through the cable to any lengthy time required to reach the buffer, so the pixel clock is held low. 此外,当对显示内容进行缓冲且准备好显示时,可将显示内容快速传送到显示器,以使得其可被保持且向各自眼睛显示较长时间。 Further, when the display content and display-ready buffer, the display content can be quickly transferred to the display, so that it can be held for a long time and displayed to the respective eyes. 因此,可通过以前述方式对显示内容进行缓冲、同时避免对增加显示器接ロ电缆上的垂直消隐间隔的需要等来增加显示内容的稳定时间。 Thus, in the foregoing manner can be performed by the display contents of the buffer, while avoiding the need to increase the monitor with ro vertical blanking interval on the cable or the like to increase the settling time of the display content.

[0070] 总的来说,可对从内容源接收到的用于预定眼睛的显示内容进行缓冲直到可获得用于此眼睛的显示内容的完整图像为止。 [0070] In general, the display content received from a content source to a predetermined eye is buffered until the complete data available so far for this image display the contents of the eye. 虽然发生此类缓冲,但仍可显示用于另一眼睛的先前显示内容。 While such buffering occurs, but still displays a further eye previously displayed content. 当此类缓冲完成且图像稳定时,可在垂直消隐间隔的持续时间或更长时间期间将用于此眼睛的显示内容的完整图像从缓冲器传送到显示器。 When such a buffer is completed and the image stabilization, the image display may be a complete content of this eye in the vertical blanking interval duration or longer during the transfer from the buffer to the display. 此外,此类传送可以显示器能够在内部处置的最大像素速率进行,以使得垂直消隐间隔能够最大化。 Further, such a display may be capable of transmitting a maximum pixel rate of the internal disposition, so that the vertical blanking interval can be maximized. 如果此类间隔太短,那么可使用可临时接收且存储下ー个传入图像的额外缓沖。 If such interval is too short, it may be used to temporarily receive and buffer incoming ー additional next image storage. 为此,可延长眼睛遮光器可維持在打开方位中的持续时间(且因此最大化屏幕亮度等)。 To this end, extend the eye shutters can be maintained in the open position in duration (and therefore maximize screen brightness, etc.).

[0071] 严格来说,作为ー选择,可在遮光器的至少ー者处于打开方位中时才启动显示器的背光。 [0071] Strictly speaking, as ー Alternatively, start may be open orientation when the display is backlit by at least ー shutters. 可在闪烁或滚动背光的情境下应用此特征。 This feature can be applied in the context of the backlight blinking or rolling. 在闪烁背光的状况下,背光可在(例如)30%的时间期间闪烁,但也可使用具有三倍量值的光,以便提供正常光输出。 In the flashing backlight conditions, the backlight may be (e.g.) 30% during the time of blinking, but may also be used with three times the magnitude of light, so as to provide normal light output. 为此,可使用本特征来避免在遮光器关闭时浪费光(和相关联的电力),且进一歩避免过热。 For this reason, this feature may be used to avoid shutting down a waste of light (and associated power) in the shutter, and into a ho avoid overheating.
