Descriptions of well-known parts are omitted for clarity and conciseness, and like reference numbers refer to like elements throughout.

图1示出根据第一示例实施例的显示系统1的说明性实例。FIG. 1 shows an illustrative example of a display system 1 according to a first example embodiment.

如图1所示，根据本示例实施例的显示系统1包括：显示装置100，其处理从外面输入的图像信号以显示图像；以及多视图设备200，其与显示装置100上显示的图像相一致地操作。As shown in FIG. 1 , a display system 1 according to this exemplary embodiment includes: adisplay device 100 that processes an image signal input from the outside to display an image; to operate.

在本示例实施例中，多视图设备200是3D眼镜200，其作用是当显示装置100显示三维（3D）图像时有选择地发送或阻挡与3D图像相对应的光线。然而，当显示设备100不仅显示3D图像而且显示至少两个不同的内容图像时，可以使用多视图设备200。In this example embodiment, themulti-view device 200 is3D glasses 200 that function to selectively transmit or block light corresponding to a 3D image when thedisplay apparatus 100 displays a three-dimensional (3D) image. However, themulti-view device 200 may be used when thedisplay device 100 displays not only a 3D image but also at least two different content images.

显示装置100从外部图像源（未示出）接收图像信号。没有特别限制图像源，并且可以从各种图像源的任何之一给显示装置100提供图像信号，例如，通过使用中央处理单元（CPU）（未示出）和图形卡（未示出）产生图像信号并且本地地提供信号的主计算机（未示出），提供图像信号给网络的服务器（未示出），以及使用地波或线缆发送广播信号的广播台的发送器（未示出）。Thedisplay device 100 receives an image signal from an external image source (not shown). The image source is not particularly limited, and thedisplay device 100 may be supplied with an image signal from any of various image sources, for example, by using a central processing unit (CPU) (not shown) and a graphics card (not shown) to generate an image A host computer (not shown) that provides the signal and locally provides the signal, a server (not shown) that provides the image signal to the network, and a transmitter (not shown) of a broadcasting station that transmits the broadcast signal using ground waves or cables.

On the contrary, if the right-eye image frame is displayed on thedisplay apparatus 100, theshutter glasses 200 open the right-eye view and block the left-eye view.

为了使显示装置100上显示的3D图像与快门眼镜200的选择性的光线发送/阻挡操作匹配，显示装置100产生同步信号或信标信号以便与图像帧的显示时序同步，并且给快门眼镜200发送该信号。快门眼镜200基于所接收的信标信号执行光线发送/阻挡操作。In order to match the 3D image displayed on thedisplay device 100 with the selective light transmission/blocking operation of theshutter glasses 200, thedisplay device 100 generates a synchronization signal or a beacon signal to synchronize with the display timing of the image frame, and sends it to theshutter glasses 200. the signal.

信号处理单元120可以被提供作为集成的多功能组件，例如片上系统（SOC），或者作为通过安装在印制电路板（PCB）上独立执行单个处理并且被安装在显示装置100中的分离元件形成的图像处理板（未示出）。Thesignal processing unit 120 may be provided as an integrated multifunctional component such as a system on chip (SOC), or formed as a discrete element that independently performs a single process by being mounted on a printed circuit board (PCB) and mounted in thedisplay device 100 image processing board (not shown).

显示单元130基于从信号处理单元120输出的图像信号显示图像。显示单元130可以被配置成使用例如液晶、等离子、发光二极管、有机发光二极管、表面传导电子发射、碳纳米管、纳米晶体等等但不限于此的各种显示模式的任何之一，。Thedisplay unit 130 displays an image based on the image signal output from thesignal processing unit 120 .

Thecommunication unit 140 is provided in accordance with bidirectional RF wireless communication standards such as RF and Bluetooth, and performs transmission and reception of various unrestricted signals/information/data including beacon signals between thedisplay apparatus 100 and theshutter glasses 200 .

此后，将描述快门眼镜200的每个组件。Hereinafter, each component of theshutter glasses 200 will be described.

眼镜通信单元210基于通信单元140的通信标准被配置，并且将从通信单元140无线接收的信标信号发送给眼镜控制器240。眼镜通信单元210可以通过不仅从通信单元140接收数据而且可以给通信单元140发送数据，执行与通信单元140的双向通信。Theglasses communication unit 210 is configured based on the communication standard of thecommunication unit 140 , and transmits a beacon signal wirelessly received from thecommunication unit 140 to theglasses controller 240 . Theglasses communication unit 210 can perform two-way communication with thecommunication unit 140 by not only receiving data from thecommunication unit 140 but also sending data to thecommunication unit 140 .

透镜单元220的作用是基于由眼镜控制器240实现的控制，选择性地发送/阻挡到用户双眼的光线。透镜单元220对于用户的左眼和右眼的每个执行有选择的光线发送，并且因此所述用户分别用左眼和右眼感觉到在显示单元130上显示的左眼图像和右眼图像。Thelens unit 220 functions to selectively transmit/block light to both eyes of the user based on the control realized by theglasses controller 240 . Thelens unit 220 performs selective light transmission for each of the user's left and right eyes, and thus the user perceives the left-eye image and the right-eye image displayed on thedisplay unit 130 with the left and right eyes, respectively.

透镜单元220可以被配置为任何类型，例如液晶透镜单元，其作用是当从眼镜控制器240施加预设电压电平时阻挡光线，以及当不施加所述的预设电压电平时发送光线。可替换地，取决于所应用的电压电平，透镜单元220可以具有可变的光透射率。Thelens unit 220 may be configured in any type, such as a liquid crystal lens unit, which functions to block light when a preset voltage level is applied from theglasses controller 240 and transmit light when the preset voltage level is not applied. Alternatively, thelens unit 220 may have variable light transmittance depending on the applied voltage level.

电池230为操作快门眼镜200的每个组件供电。电池230被提供作为原电池或二次电池，优选地，可利用外部公共电力充电的二次电池。电池230由眼镜控制器240控制，从而控制是否给特定组件输出电能或输出电压电平。Thebattery 230 provides power to operate each component of theshutter glasses 200 . Thebattery 230 is provided as a primary battery or a secondary battery, preferably, a secondary battery chargeable using external public power. Thebattery 230 is controlled by theglasses controller 240 to control whether to output power or output voltage levels to specific components.

眼镜控制器240基于由眼镜通信单元210所接收的信标信号有选择地将电压施加于透镜单元220，从而驱动透镜单元220。眼镜控制器240在左眼图像被显示的垂直同步时段内操作透镜单元220以发送到用户左眼的光线以及阻挡到用户右眼的光线。相反地，眼镜控制器240在右眼图像被显示的垂直同步时段内操作透镜单元220以发送到用户右眼的光线以及阻挡到用户左眼的光线。进一步，图像被扫描到显示单元130上时，眼镜控制器240操作透镜单元220阻挡到用户双眼的光线。前述的操作被提供用于说明目的，以说明眼镜控制器240驱动透镜单元220，但不限制本示例实施例的范围。Theglasses controller 240 selectively applies a voltage to thelens unit 220 based on the beacon signal received by theglasses communication unit 210 , thereby driving thelens unit 220 . Theglasses controller 240 operates thelens unit 220 to transmit light to the user's left eye and block light to the user's right eye during a vertical synchronization period in which the left-eye image is displayed. On the contrary, theglasses controller 240 operates thelens unit 220 to transmit light to the user's right eye and block light to the user's left eye during the vertical synchronization period in which the right eye image is displayed. Further, when the image is scanned onto thedisplay unit 130, theglasses controller 240 operates thelens unit 220 to block the light to the user's eyes. The aforementioned operations are provided for illustrative purposes to explain that theglasses controller 240 drives thelens unit 220 , but do not limit the scope of the present exemplary embodiment.

此后，将参照图4描述显示装置100和快门眼镜200之间实现以与在显示装置100上显示的3D图像的显示时段同步地操作快门眼镜200的信号发送/接收过程。图4是示出显示装置100和快门眼镜200之间的信号发送和接收的示意图。Hereinafter, a signal transmission/reception process implemented between thedisplay device 100 and theshutter glasses 200 to operate theshutter glasses 200 in synchronization with a display period of a 3D image displayed on thedisplay device 100 will be described with reference to FIG. 4 . FIG. 4 is a schematic diagram illustrating signal transmission and reception between thedisplay device 100 and theshutter glasses 200 .

首先如图4所示，显示装置100与快门眼镜200的配对或关联是必要的，以便快门眼镜200接收来自显示装置100的信标信号并且与信标信号相一致地操作。First, as shown in FIG. 4 , pairing or association of thedisplay device 100 and theshutter glasses 200 is necessary so that theshutter glasses 200 receive a beacon signal from thedisplay device 100 and operate in accordance with the beacon signal.

为了创建配对，在操作310中，用户通过使用快门眼镜200引发触发事件以开始配对。所述触发事件可以作为各种动作的任何之一的结果出现，例如，用户通过快门眼镜200检索到在快门眼镜200的通信范围之内的显示装置100。To create pairing, inoperation 310 , the user triggers a trigger event by using theshutter glasses 200 to start pairing. The triggering event may occur as a result of any one of various actions, for example, the user retrieves thedisplay device 100 within the communication range of theshutter glasses 200 through theshutter glasses 200 .

在操作320中，快门眼镜200向显示装置100发送包含配对请求的询问分组。Inoperation 320 , theshutter glasses 200 transmit an inquiry packet including a pairing request to thedisplay apparatus 100 .

在操作330中，显示装置100给快门眼镜200发送询问响应分组以响应从快门眼镜200收到的询问分组。所述询问响应分组可以包括，例如，与显示装置100的生厂商相关的信息、与用于分组发送的显示装置100的输出电平有关的信息或其他相关信息。Inoperation 330 , thedisplay apparatus 100 transmits an inquiry response packet to theshutter glasses 200 in response to the inquiry packet received from theshutter glasses 200 . The inquiry response packet may include, for example, information related to the manufacturer of thedisplay device 100, information related to the output level of thedisplay device 100 for packet transmission, or other related information.

在操作340中，快门眼镜200从显示装置100接收询问响应分组，从而完成显示装置100与快门眼镜200的配对。在这个阶段，快门眼镜200给显示装置100发送确认询问响应分组接收的关联通知分组，并且显示装置100给快门眼镜200发送确认接收关联通知分组的分组，从而完成创建配对过程。Inoperation 340 , theshutter glasses 200 receive an inquiry response packet from thedisplay apparatus 100 , thereby completing pairing of thedisplay apparatus 100 and theshutter glasses 200 . At this stage, theshutter glasses 200 transmit to the display apparatus 100 a packet confirming reception of the association notification packet to thedisplay apparatus 100, and thedisplay apparatus 100 sends a packet to theshutter glasses 200 to confirm reception of the association notification packet, thereby completing the creating pairing process.

特别地，从快门眼镜200给显示装置发送的关联通知分组可以包括，例如，快门眼镜200的地址；快门眼镜200的设备类型；与电池的特征和电池剩余量有关的信息；和/或其它相关信息。以此方式，可以在显示装置100和快门眼镜200之间交换个体特征信息，从而实现组件的配对或关联。In particular, the association notification packet sent from theshutter glasses 200 to the display device may include, for example, the address of theshutter glasses 200; the device type of theshutter glasses 200; information related to the characteristics of the battery and the remaining amount of the battery; and/or other relevant information. In this way, individual characteristic information can be exchanged between thedisplay apparatus 100 and theshutter glasses 200, thereby enabling pairing or association of components.

在操作350中，当配对已经创建时，快门眼镜200在从完成配对创建开始的预设时间内等待接收重连接链分组（reconnection train packet）。如果在预设时间内没有接收到重连接链分组，则快门眼镜200可以给显示装置100发送包含重连接链分组的发送请求的分组。Inoperation 350, when the pairing has been created, theshutter glasses 200 wait to receive a reconnection train packet for a preset time from completion of pairing creation. If the reconnection chain packet is not received within a preset time, theshutter glasses 200 may transmit a packet including a transmission request of the reconnection chain packet to thedisplay device 100 .

在操作360中，显示装置100给快门眼镜200发送重连接链分组。所述的重连接链分组包含快门眼镜200接收信标信号分组所需的信息。例如，所述的重连接链分组可以包括：显示装置100的通信时钟；显示装置100的地址；与信标分组时段有关的信息；和/或其它相关信息。Inoperation 360 , thedisplay apparatus 100 transmits a reconnection chain packet to theshutter glasses 200 . The reconnection chain packet contains information required for theshutter glasses 200 to receive the beacon signal packet. For example, the reconnection chain packet may include: the communication clock of thedisplay device 100; the address of thedisplay device 100; information related to the period of the beacon group; and/or other relevant information.

在操作370中，快门眼镜200基于所接收的重连接链分组完成针对连接到显示装置100的配置实现，并且执行与显示在显示装置100上的图像同步。Inoperation 370 , theshutter glasses 200 complete configuration implementation for connection to thedisplay apparatus 100 based on the received reconnection chain packet, and perform synchronization with an image displayed on thedisplay apparatus 100 .

已接收到重连接链分组后，快门眼镜200忽略随后接收的重连接链分组。因为显示装置100在完成创建配对后的预设时间内周期地发送所述重连接链分组，所以如果希望被重新连接到显示装置100，快门眼镜200可以在没有请求的情况下再次接收重连接链分组以被重新连接到显示装置100。Having received a reconnection chain packet, theshutter glasses 200 ignore subsequent received reconnection chain packets. Since thedisplay device 100 periodically transmits the reconnection chain packet within a preset time after the pairing is completed, theshutter glasses 200 can receive the reconnection chain again without request if they want to be reconnected to thedisplay device 100 group to be reconnected to thedisplay device 100 .

在操作380和390中，快门眼镜200基于所述的重连接链分组接收从显示装置100周期地发送的信标分组。快门眼镜200基于所接收的信标分组操作透镜单元220与显示装置100的3D图像的显示时段同步。In operations 380 and 390, theshutter glasses 200 receive a beacon packet periodically transmitted from thedisplay apparatus 100 based on the reconnection chain packet. Theshutter glasses 200 operate thelens unit 220 in synchronization with the display period of the 3D image of thedisplay apparatus 100 based on the received beacon group.

所述信标分组可以包括，例如，以下的一个或多个：基于来自显示装置100的通信时钟的与图像有关的显示时序、针对用户双眼与操作透镜单元220快门的时序有关的延迟值、在显示装置100上显示的内容图像的运行时间、和/或在当前时间后内容图像的剩余运行时间。The beacon packet may include, for example, one or more of the following: a display timing related to an image based on a communication clock from thedisplay device 100, a delay value related to the timing of operating the shutter of thelens unit 220 for both eyes of the user, The running time of the content image displayed on thedisplay device 100, and/or the remaining running time of the content image after the current time.

使用此配置，当在显示装置100上显示内容的3D图像时，快门眼镜200与所述3D图像同步操作。With this configuration, when a 3D image of content is displayed on thedisplay device 100, theshutter glasses 200 operate in synchronization with the 3D image.

参照图1的显示系统1已经描述了前述的示例实施例，但也适用于图2的显示系统2。在这种情况下，显示系统2可以包括用于将显示装置101与快门眼镜201和202的每一个配对的单独通信终端（未示出）。The foregoing example embodiments have been described with reference to the display system 1 of FIG. 1 , but are also applicable to thedisplay system 2 of FIG. 2 . In this case, thedisplay system 2 may include a separate communication terminal (not shown) for pairing thedisplay apparatus 101 with each of theshutter glasses 201 and 202 .

所述通信终端与显示装置101分开安装以便快门眼镜201和202的用户可以容易访问所述通信终端，并且使用与显示装置101的操作特征有关的以前存储的信息，将显示装置101与快门眼镜201和202的每一个配对。The communication terminal is installed separately from thedisplay device 101 so that users of theshutter glasses 201 and 202 can easily access the communication terminal, and use previously stored information related to the operating characteristics of thedisplay device 101 to connect thedisplay device 101 to theshutter glasses 201. Pair with each of 202.

例如，在图4的操作310、320、330、和340的每一个中，可以在所述通信终端与快门眼镜201和202之间执行分组的发送/接收，而不是在显示装置101与快门眼镜201和202之间执行分组的发送/接收，并且在操作360、370、380和390的每一个中，可以在显示装置101与快门眼镜201和202之间执行分组的发送/接收。For example, in each ofoperations 310, 320, 330, and 340 of FIG. 4 , transmission/reception of packets may be performed between the communication terminal and theshutter glasses 201 and 202 instead of between thedisplay device 101 and the shutter glasses. Transmission/reception of packets is performed between 201 and 202 , and in each ofoperations 360 , 370 , 380 , and 390 , transmission/reception of packets may be performed between thedisplay apparatus 101 and theshutter glasses 201 and 202 .

使用通信终端而不是显示装置101执行配对操作可以获得以下效果。Performing the pairing operation using the communication terminal instead of thedisplay device 101 can obtain the following effects.

在如图2所示的电影院环境中，多个剧场可以被互相邻近提供。特别地，可以提供多个显示装置101，显示装置的每一个分别显示不同的图像，信标信号发送设备102可以被安装以分别发送与各自显示装置101相对应的信号或分组，并且装置101和设备102可以被分别互相邻近布置。In a movie theater environment as shown in Figure 2, multiple theaters may be provided adjacent to each other. In particular, a plurality ofdisplay devices 101 may be provided, each of the display devices displays a different image, the beaconsignal transmitting device 102 may be installed to respectively transmit signals or groups corresponding to therespective display devices 101, and thedevices 101 andDevices 102 may be respectively arranged adjacent to each other.

如果经由信标信号发送设备102执行配对操作，则快门眼镜201和202可能被与正在显示的不相关图像的显示装置101配对，而不是与当前正在呈现用户观看的图像的显示装置101配对。这种场合可能发生，例如，当用户位于离信标信号发送设备102相对远的剧场角落时，并且从另一个被布置在墙外的信标信号发送设备102当前发送的信号相对强时。If the pairing operation is performed via the beaconsignal transmitting device 102, theshutter glasses 201 and 202 may be paired with thedisplay device 101 that is displaying an unrelated image instead of thedisplay device 101 that is currently presenting the image viewed by the user. Such an occasion may occur, for example, when the user is located at a theater corner relatively far from the beaconsignal transmitting device 102, and the signal currently transmitted from another beaconsignal transmitting device 102 arranged outside the wall is relatively strong.

因此，如果经由通信终端执行配对操作，则快门眼镜201和202从对应的信标信号发送设备102有选择地接收重连接链分组和信标分组，即使从不相关的信标信号发送设备102发送的信号相对强。Therefore, if the pairing operation is performed via the communication terminal, theshutter glasses 201 and 202 selectively receive the reconnection chain packet and the beacon packet from the corresponding beaconsignal transmitting device 102 even if transmitted from the irrelevant beaconsignal transmitting device 102 The signal is relatively strong.

图5示出快门眼镜200接收由显示装置100发送的信标分组b的示例时序。FIG. 5 shows an example timing sequence in which theshutter glasses 200 receive the beacon packet b transmitted by thedisplay apparatus 100 .

如图5中所示，上面的图形410是示出由显示装置100发送信标分组b的时序图，以及下面的图形420是示出由快门眼镜200接收信标分组b的时序图。在图形410和420两者中水平轴表示时间。As shown in FIG. 5 , theupper graph 410 is a timing diagram showing transmission of the beacon packet b by thedisplay device 100 , and thelower graph 420 is a timing diagram showing reception of the beacon packet b by theshutter glasses 200 . In bothgraphs 410 and 420 the horizontal axis represents time.

显示装置100在每个预定时间间隔t1向外周期地发送信标分组b一次。Thedisplay device 100 periodically transmits the beacon packet b once every predetermined time interval t1.

然而，因为快门眼镜200通常使用内置电池230，所以当用户正在观看诸如电影的具有长运行时间的内容时，快门眼镜200可能或可能无法连续操作。因此，对于快门眼镜200来说，通过最低限度地消耗电池230的能量以获得尽可能长的操作时间是重要的。However, since theshutter glasses 200 generally use the built-inbattery 230, theshutter glasses 200 may or may not be able to operate continuously when the user is watching content with a long running time, such as a movie. Therefore, it is important for theshutter glasses 200 to obtain as long an operation time as possible by consuming the energy of thebattery 230 to a minimum.

为了这个目的，快门眼镜200在每个时间间隔t2从显示装置100接收信标分组b一次，t2比t1（即显示装置100的发送时段）长。假如t2比t1长，不特别限制时间间隔t2的长度。在一些示例实施例中，时间间隔t2可以被设定为t1整数倍的缺省值。例如，t1可以等于80ms，并且t2可以被设定等于560ms，其是t1长度的7倍。For this purpose, theshutter glasses 200 receive the beacon packet b from thedisplay device 100 once every time interval t2 which is longer than t1 (ie, the transmission period of the display device 100 ). If t2 is longer than t1, the length of time interval t2 is not particularly limited. In some example embodiments, the time interval t2 may be set to a default value that is an integer multiple of t1. For example, t1 may be equal to 80ms, and t2 may be set equal to 560ms, which is 7 times the length of t1.

快门眼镜200在从信标分组b被接收的第一时间点421到下一个信标分组b被接收的第二时间点422的间隔t2内不激活眼镜通信单元210，因此不接收信标分组b而基于在第一时间点421接收的信标分组b操作透镜单元220。这种操作被称为自由运行操作。Theshutter glasses 200 do not activate theglasses communication unit 210 within the interval t2 from thefirst time point 421 when the beacon packet b is received to thesecond time point 422 when the next beacon packet b is received, and thus do not receive the beacon packet b And thelens unit 220 is operated based on the beacon packet b received at thefirst time point 421 . Such an operation is called a free-running operation.

在第二时间点422，快门眼镜200激活眼镜通信单元210并且接收信标分组b。在接收信标分组b之后，快门眼镜200又不激活眼镜通信单元210并且以自由运行模式操作透镜单元220。At thesecond time point 422, theshutter glasses 200 activate theglasses communication unit 210 and receive the beacon packet b. After receiving the beacon packet b, theshutter glasses 200 again do not activate theglasses communication unit 210 and operate thelens unit 220 in a free-running mode.

特别地，快门眼镜200以长于显示装置100的发送时段t1的间隔t2周期地接收信标分组b，并且在它们不接收信标分组b的间隔t2期间不激活眼镜通信单元210，从而节省电池230的耗电。In particular, theshutter glasses 200 periodically receive the beacon packet b at an interval t2 longer than the transmission period t1 of thedisplay device 100, and do not activate theglasses communication unit 210 during the interval t2 during which they do not receive the beacon packet b, thereby saving thebattery 230 power consumption.

然而，如果电池230被完全充满但是内容图像有相对长的运行时间，则快门眼镜200有可能可以在完成内容图像显示之前终止操作。特别地，当内容图像具有相对长的运行时间时，有必要进一步节省电池230的耗电。However, if thebattery 230 is fully charged but the content image has a relatively long running time, there is a possibility that theshutter glasses 200 can terminate the operation before the display of the content image is completed. In particular, when a content image has a relatively long running time, it is necessary to further save power consumption of thebattery 230 .

为此，根据本示例实施例的快门眼镜200具有以下的配置。For this reason, theshutter glasses 200 according to the present exemplary embodiment have the following configuration.

快门眼镜200从自显示装置100接收的信标分组b中提取与内容图像的运行时间有关的信息，并且基于所提取的与内容图像运行时间有关的信息通过眼镜通信单元210控制信标分组b的接收频率被改变。Theshutter glasses 200 extract information on the running time of the content image from the beacon packet b received from thedisplay device 100, and control the opening and closing of the beacon packet b through theglasses communication unit 210 based on the extracted information on the running time of the content image. The reception frequency is changed.

通过以下的方法改变信标分组b的接收频率。The reception frequency of the beacon packet b is changed by the following method.

因为内容图像具有相对较长的运行时间，所以快门眼镜200将信标分组b的接收频率减少到低于缺省值。因为所述接收频率是每单位时间接收信标分组b的次数，接收时间的减少导致（entail）较长的信标分组b的接收周期。Because the content image has a relatively long running time, theshutter glasses 200 reduce the reception frequency of the beacon packet b to be lower than a default value. Since the reception frequency is the number of times the beacon packet b is received per unit time, reduction of the reception time entails a longer reception period of the beacon packet b.

例如，在示出快门眼镜200接收信标分组b的图4的图形420中，在接收信标分组b的周期t2为缺省值的实例中，t1被预设为80ms，t2被预设为560ms。在这种情形中，基于内容的运行时间可以确定t2的缺省值560ms。For example, in thegraph 420 of FIG. 4 showing that theshutter glasses 200 receive the beacon packet b, in the example where the period t2 of receiving the beacon packet b is a default value, t1 is preset to 80 ms, and t2 is preset to 560ms. In this case, a default value of 560 ms for t2 may be determined based on the runtime of the content.

如图形430中所示，如果确定从信标分组b中提取的内容的运行时间长于参考运行时间，则快门眼镜200可以将信标分组b的接收周期调整为相对长于缺省值t2的t3。参照上述的实例，快门眼镜200可以将t3设置为640ms，其是间隔t1长度的8倍，从而将快门眼镜200的接收频率减少为低于所述缺省值。因此，减少了每单位时间激活眼镜通信单元210的次数，从而进一步节省了电池230的耗电。As shown in thegraph 430, if it is determined that the running time of the content extracted from the beacon packet b is longer than the reference running time, theshutter glasses 200 may adjust the receiving period of the beacon packet b to t3 which is relatively longer than the default value t2. Referring to the above example, theshutter glasses 200 may set t3 to 640 ms, which is 8 times the length of the interval t1, thereby reducing the reception frequency of theshutter glasses 200 below the default value. Therefore, the number of activations of theglasses communication unit 210 per unit time is reduced, thereby further saving power consumption of thebattery 230 .

相反，如果确定从信标分组b中提取的内容的运行时间短于参考运行时间，则快门眼镜200可以保持快门眼镜200的接收频率等于缺省值。可替换地，快门眼镜200可以将t2调整到相对短以便保证透镜单元220的同步质量，从而将快门眼镜200的接收频率增加为高于缺省值。假如电池230的剩余电量保证在内容的整个运行时间快门眼镜200的连续操作，可以运行后面的操作。On the contrary, if it is determined that the running time of the content extracted from the beacon packet b is shorter than the reference running time, theshutter glasses 200 may keep the receiving frequency of theshutter glasses 200 equal to a default value. Alternatively, theshutter glasses 200 may adjust t2 to be relatively short in order to ensure the synchronization quality of thelens unit 220, thereby increasing the receiving frequency of theshutter glasses 200 higher than a default value. Provided that the remaining power of thebattery 230 ensures continuous operation of theshutter glasses 200 throughout the running time of the content, the latter operations can be performed.

可以在开始显示内容图像时或者在预设的时间段期间运行前述的过程，或者当显示内容图像时周期执行前述的过程，其中在前述的过程中，快门眼镜200从信标分组b中提取与内容图像运行时间有关的信息，并且基于所提取的与内容图像运行时间有关的信息改变信标分组b的接收频率。The aforementioned process may be executed when the display of the content image is started or during a preset period of time, or may be performed periodically when the content image is displayed, wherein in the aforementioned process, theshutter glasses 200 extract information related to the beacon group b. information about the running time of the content image, and changes the reception frequency of the beacon packet b based on the extracted information about the running time of the content image.

在后面的情形中，信标分组b包括根据相应的发送时间计算的内容图像的剩余运行时间，快门眼镜200可以在接收到信标分组b的时间点基于内容图像的剩余运行时间调整所述的接收频率。在此情形中，能够精确地控制在显示内容图像时快门眼镜200的剩余电池能量。In the latter case, the beacon packet b includes the remaining running time of the content image calculated according to the corresponding transmission time, and theshutter glasses 200 may adjust the remaining running time of the content image based on the time point when the beacon packet b is received. receive frequency. In this case, it is possible to accurately control the remaining battery power of theshutter glasses 200 while displaying the content image.

已经参照快门眼镜200仅仅考虑内容运行时间的情形描述了前述的示例实施例，但是可以进行各种各样的修改。The foregoing exemplary embodiment has been described with reference to the case where theshutter glasses 200 consider only the content execution time, but various modifications are possible.

具体来说，快门眼镜200在获得与内容运行时间有关的信息时检查电池230的剩余电量。如果基于电池230的剩余电量确定电池230不能在内容的整个运行时间为操作快门眼镜200供电，则快门眼镜200可以将信标分组b的接收频率减少到小于缺省值。Specifically, theshutter glasses 200 check the remaining power of thebattery 230 when obtaining information on the running time of the content. If it is determined based on the remaining power of thebattery 230 that thebattery 230 cannot provide power to operate theshutter glasses 200 throughout the running time of the content, theshutter glasses 200 may reduce the reception frequency of the beacon packet b to less than a default value.

另外，如果确定与所获得的内容运行时间相对应地改变信标分组b的接收频率，或者基于电池230的剩余电量确定电池230不能在整个的内容运行时间为操作快门眼镜200供电，则快门眼镜200可以控制出错消息通知用户被显示的确定结果。In addition, if it is determined that the reception frequency of the beacon packet b is changed corresponding to the obtained content running time, or it is determined based on the remaining power of thebattery 230 that thebattery 230 cannot supply power for operating theshutter glasses 200 throughout the content running time, theshutter glasses 200 may control the error message to inform the user of the displayed determination result.

所述出错消息可以包括指示在显示内容图像时不保证快门眼镜200的操作的信息、报告电池230需要充电的信息、或者报告快门眼镜200需要更换的信息。The error message may include information indicating that the operation of theshutter glasses 200 is not guaranteed when displaying content images, information reporting that thebattery 230 needs to be charged, or information reporting that theshutter glasses 200 need to be replaced.

可以在显示装置100上或者在快门眼镜200上显示所述出错消息。在前面情形中，快门眼镜200将与出错消息相对应的信息发送给显示装置100，以便在显示装置100上显示出错消息，并且显示装置100基于从快门眼镜200接收的信息显示图像。在后面的情形中，快门眼镜200可以将出错消息显示在透镜单元220上，以便佩戴着快门眼镜200的用户识别出所述消息。The error message can be displayed on thedisplay device 100 or on theshutter glasses 200 . In the foregoing case, theshutter glasses 200 transmit information corresponding to the error message to thedisplay device 100 to display the error message on thedisplay device 100 , and thedisplay device 100 displays an image based on the information received from theshutter glasses 200 . In the latter case, theshutter glasses 200 may display an error message on thelens unit 220 so that the user wearing theshutter glasses 200 recognizes the message.

可以在适当时间显示出错消息以便不中断用户观看内容图像。例如，快门眼镜200可以不在内容运行时间的中间，而是在用于显示广告的休息时间显示或呈现出错消息。An error message may be displayed at an appropriate time so as not to interrupt the user's viewing of the content image. For example, theshutter glasses 200 may display or present error messages not in the middle of content runtime, but during breaks for displaying advertisements.

在前述的示例实施例中，快门眼镜200从信标分组b获得与内容图像运行时间有关的信息，但是可以通过其它方法获得所述信息。例如，所述信息可以被包含在询问响应分组330中（见图4），或者在重连接链分组360中（见图4），而不是在信标分组b中，并且快门眼镜200可以从相应分组中提取与内容运行时间有关的信息。In the aforementioned exemplary embodiments, theshutter glasses 200 obtain the information on the content image runtime from the beacon packet b, but the information may be obtained by other methods. For example, the information may be included in the inquiry response packet 330 (see FIG. 4 ), or in the reconnection chain packet 360 (see FIG. 4 ) instead of the beacon packet b, and theshutter glasses 200 may receive from the corresponding Extract information about the runtime of the content in the group.

可替换地，快门眼镜200可以不从信标分组b中提取所述信息，而是接收从显示装置100发送的独立信息分组。Alternatively, theshutter glasses 200 may not extract the information from the beacon packet b, but receive an independent information packet transmitted from thedisplay device 100 .

此后将参照图6描述根据本示例实施例的通过使用3D眼镜实现的控制方法。图6是示出通过使用3D眼镜实现的控制方法的流程图。Hereinafter, a control method realized by using 3D glasses according to the present exemplary embodiment will be described with reference to FIG. 6 . FIG. 6 is a flowchart illustrating a control method implemented by using 3D glasses.

如图6中所示，在操作S100中，3D眼镜与显示装置进行或创建配对。然后，在操作S110中，3D眼镜从所配对的显示装置接收信标信号。As shown in FIG. 6, in operation S100, the 3D glasses perform or create pairing with the display device. Then, the 3D glasses receive a beacon signal from the paired display device in operation S110.

在操作S120中，3D眼镜从信标信号中获得与内容图像运行时间有关的信息。然后，在操作S130中，3D眼镜基于所获得的与运行时间有关的信息改变信标信号的接收频率。In operation S120, the 3D glasses obtain information on the content image runtime from the beacon signal. Then, in operation S130, the 3D glasses change the reception frequency of the beacon signal based on the obtained runtime-related information.

在操作S140中，3D眼镜以被改变的接收频率接收信标信号，并且在操作S150中，3D眼镜操作透镜单元以便根据所接收的信标信号选择性地传送/阻挡到用户双眼的光线。In operation S140, the 3D glasses receive the beacon signal at the changed reception frequency, and in operation S150, the 3D glasses operate the lens unit to selectively transmit/block light to both eyes of the user according to the received beacon signal.

以这种方式可以控制3D眼镜。In this way the 3D glasses can be controlled.

在另一示例实施例中，如果在播放内容图像的时间点确定电池230不能在内容的剩余运行时间为操作快门眼镜200供电，则快门眼镜200可以通过眼镜通信单元210改变信标信号的接收频率。可替换地，快门眼镜200可以计算出不再接收信标信号但是随后以自由运行模式操作透镜单元的特定时间点。将参照图7描述这种控制方法。图7是示出通过使用快门眼镜200实现的控制方法的流程图。In another example embodiment, if it is determined at the time point when the content image is played that thebattery 230 cannot supply power for operating theshutter glasses 200 during the remaining running time of the content, theshutter glasses 200 may change the receiving frequency of the beacon signal through theglasses communication unit 210 . Alternatively, theshutter glasses 200 may calculate a certain time point at which the beacon signal is no longer received but then operates the lens unit in the free-running mode. This control method will be described with reference to FIG. 7 . FIG. 7 is a flowchart showing a control method realized by using theshutter glasses 200 .

如图7中所示，在操作S200中，快门眼镜200可以在特定操作时间获得如下的参数：As shown in FIG. 7, in operation S200, theshutter glasses 200 may obtain the following parameters at a specific operation time:

Tr：内容的剩余运行时间（单位：秒（sec））；Tr: the remaining running time of the content (unit: second (sec));

Tb：信标信号的接收周期（单位：sec）；Tb: receiving period of beacon signal (unit: sec);

Pb：当接收信标信号时的耗电量（单位：毫安时（mAh））；Pb: power consumption when receiving a beacon signal (unit: milliampere-hour (mAh));

Ps：当驱动透镜单元220时每个单位时间的耗电量（单位：mAh/sec）；以及Ps: power consumption per unit time when driving the lens unit 220 (unit: mAh/sec); and

Pg：从当前时间在电池230中存储的剩余电量（单位：mAh）Pg: remaining power stored in thebattery 230 from the current time (unit: mAh)

快门眼镜200可以从自显示装置100周期接收的信标信号中提取Tr。其它参数涉及快门眼镜200的透镜单元220、眼镜通信单元210和电池230。仅仅为了方便示出各个参数的单位，因此各个参数的单位可以根据设备的配置来改变。Theshutter glasses 200 may extract Tr from a beacon signal periodically received from thedisplay device 100 . Other parameters relate to thelens unit 220 of theshutter glasses 200 , theglasses communication unit 210 and thebattery 230 . The units of the respective parameters are shown for convenience only, and thus the units of the respective parameters may be changed according to the configuration of the device.

在操作S210中，快门眼镜200可以通过使用所获得参数计算出以下信息：In operation S210, theshutter glasses 200 may calculate the following information by using the obtained parameters:

[Tr*Ps]：在内容的剩余运行时间驱动透镜单元220的耗电量（单位：mAh）；[Tr*Ps]: power consumption for driving thelens unit 220 during the remaining running time of the content (unit: mAh);

[Tr/Tb]：在内容的剩余运行时间接收信标信号的数量（单位未规定）；以及[Tr/Tb]: the number of received beacon signals (in unspecified units) during the remaining runtime of the content; and

[{Tr/Tb}*Pb]：在内容的剩余运行时间接收信标信号的耗电量（单位：mAh）。[{Tr/Tb}*Pb]: Power consumption (unit: mAh) for receiving beacon signals during the remaining running time of the content.

通过使用以上信息，在操作S220中，快门眼镜200可以基于以下方程计算出Pr，其是在从当前时间的剩余运行时间接收信标信号所需要的电量：By using the above information, in operation S220, theshutter glasses 200 may calculate Pr, which is the power required to receive the beacon signal during the remaining running time from the current time, based on the following equation:

Pr=[{Tr/Tb}*Pb]+[Tr*Ps]（单位：mAh）Pr=[{Tr/Tb}*Pb]+[Tr*Ps] (unit: mAh)

在操作S230中，快门眼镜200把Pr与Pg进行比较。如果Pg大于Pr，则在操作S240中，快门眼镜200不改变操作模式，而是保持当前操作模式。然而，如果[Tr*Ps]<Pg<Pr，如操作S250中所确定的，则快门眼镜200在操作S260中通过眼镜通信单元210将信标信号的接收频率减少到低于原始值，或者快门眼镜200计算出不再接收信标信号的特定时间点，而代之以在操作S270中，快门眼镜200以自由运行模式操作透镜单元220。In operation S230, theshutter glasses 200 compare Pr with Pg. If Pg is greater than Pr, theshutter glasses 200 do not change the operation mode but maintain the current operation mode in operation S240. However, if [Tr*Ps]<Pg<Pr, as determined in operation S250, theshutter glasses 200 reduce the reception frequency of the beacon signal to be lower than the original value through theglasses communication unit 210 in operation S260, or theshutter glasses 200 Theglasses 200 calculate a specific time point at which the beacon signal is no longer received, and instead theshutter glasses 200 operate thelens unit 220 in a free running mode in operation S270.

特别地，确定是否[Tr*Ps]<Pg被考虑，因为如果在从当前时间开始的内容的剩余运行时间内不操作眼镜通信单元210的情况下，电池230的剩余电量甚至对于仅仅操作透镜单元220都不够的话，则即使不接收信标信号，也不能保证快门眼镜200的操作。In particular, it is determined whether [Tr*Ps]<Pg is considered because the remaining power of thebattery 230 is not sufficient even for operating the lens unit only if theglasses communication unit 210 is not operated within the remaining running time of the content from the current time. If all 220 are insufficient, the operation of theshutter glasses 200 cannot be guaranteed even if the beacon signal is not received.

信标信号的接收周期T可以被计算如下：The receiving period T of the beacon signal can be calculated as follows:

N=[Pg-{Tr*Ps}]/Pb(未规定单位)；以及N=[Pg-{Tr*Ps}]/Pb (unspecified units); and

T=Tr/N（单位：sec）T=Tr/N (unit: sec)

N是在内容的剩余运行时间的信标信号可能的接收数量。在操作S260中，T被增加预设倍数，从而减少了信标信号的接收频率。N is the number of possible receptions of beacon signals over the remaining runtime of the content. In operation S260, T is increased by a preset multiple, thereby reducing the reception frequency of the beacon signal.

在操作S270中，当电池230不给眼镜通信单元210供电而只给透镜单元220供电时，确定透镜单元220能够操作直到完成播放内容为止的特定时间点。所述特定时间点可以被计算如下：In operation S270, when thebattery 230 does not supply power to theglasses communication unit 210 but only supplies power to thelens unit 220, it is determined that thelens unit 220 can operate until a certain point in time until playback of the content is completed. The specific time point can be calculated as follows:

A=[[Pg-{Tr*Ps}]/Pb]*Tb（单位：sec）A=[[Pg-{Tr*Ps}]/Pb]*Tb (unit: sec)

A是时间量，并且通过从播放内容图像的终止时间减去A来确定特定时间点。当内容图像达到此特定时间点时，快门眼镜200从特定时间点开始不接收信标信号，而只是操作透镜单元220。A is an amount of time, and a specific time point is determined by subtracting A from the end time of playing the content image. When the content image reaches this specific time point, theshutter glasses 200 do not receive the beacon signal from the specific time point, but only operate thelens unit 220 .

因此，可以保证用户能够连续地观看正在被观看的图像到结束，而不管快门眼镜200的电池230的剩余电量。Therefore, it can be ensured that the user can continuously view the image being viewed to the end regardless of the remaining power of thebattery 230 of theshutter glasses 200 .
