单屏幕多频同步 2D及 3D影音系统
技术领域
本发明涉及 2D及 3D影音系统， 特别是关于一种单屏幕多频同步 2D 及 3D影音系统， 经由配戴快门眼镜， 即可使多人用单一屏幕同时收看不同 频道的 2D及 3D影音系统。 背景技术
近年来由于 3D(3维 /Three Dimensional)电影盛行，人们对于 3D影片的 需求日趋增多。 相对的 3D产品亦从电影转至 LCD产业。 首先， 人类为什 么能透过视觉看出深度、 并感觉到立体感， 最主要的一点就是， 人眼的视 觉是可以感觉出深度的， 也就是「深度知觉（depth perception)」 ； 而有了深 度的信息后， 才能判断出立体空间中的相对位置。 由于人的两个眼睛的位 置不一样， 一般人两眼间距约 5 到 7 公分， 所以看到的东西会有两眼视 差 (binocular parallax) , 而人脑会再将这两个影像做融合 (convergence) , 而 产生出立体的感觉； 而这就是所谓的 「 binocular cues」 。 另夕卜， 人类亦可 从目艮睛对远近焦距的调适 (accommodation)、 动态视差 (motion parallax)、 透 视 (perspective)或光影等来判断物体的远近， 亦即使人类只有单眼亦可判断 远近。
因此， 为了使在 2D(2维 /Two Dimensional)平面的影片变成 3D立体感 的影片， 必须使人类左、 右的眼睛分别看到不同的影像 (即是一般视物的两 眼视差）， 在经由大脑融合， 2D影片即可变为栩栩如生的 3D影片。
在现有技术中， 是运用快门镜 (shutter glasses) , 此种技术的基本原理就 是， 在屏幕上以两倍的频率交互地显示左眼和右眼的影像， 而眼镜则会去 动态地屏蔽使用者的左眼和右眼， 在屏幕显示左眼影像时遮住右眼、 在屏 幕显示右眼影像时遮住左眼， 以此达到让两眼看到各自不同的影像。 虽然 在这种状况下， 没有两只眼睛是同时看到影像的， 但是由于人眼的视觉暂 留等机制的效果， 还是能感觉到两眼都有看到各自不同的影像， 进而产生 立体感。
市售 3D显示器即是使用此项技术， 而此项技术主要是应用在 3D影像 上， 在非使用此功能时， 3D显示器与一般显示器并无差别。
在一般家庭中， 因年龄层或有多个兄弟姊妹的情况下， 通常家里需要 有多个显示器， 但有时还是不足以提供全家庭观看。 这样不只可能会使大 家争抢电视， 甚至如果还要在购入显示器时， 又是一笔开销。 而如果是 3D 显示器， 其开销又是更大。
因此， 本发明提供一种单屏幕多频同步 2D及 3D影音系统， 将 3D显 示技术加以运用，使原本 3D影像成形的左眼画面与右眼画面，转变为第一 频道与第二频道， 配合多个快门眼镜， 可使一快门眼镜提供第一频道， 另 一快门眼镜提供第二频道， 因此， 即使在只有单一屏幕的情况下， 仍可让 两人可以同时收看自己喜欢的频道。 而在显示器画面更新频率为 120hz (每 秒 120次)或以上时， 可使更多人同时收看自己喜欢的频道， 甚至是可同时 收看不同频道且皆为 3D影像的画面。 发明内容
依据上述的状况， 本发明的一主要目的在于提供一种单屏幕多频同步 2D及 3D影音系统， 利用此系统可将显示器所显示的 2D画面， 经由配戴 快门眼镜将其转换为 3D画面。
本发明的另一主要目的在于提供一种单屏幕多频同步 2D及 3D影音系 统， 利用 3D显示技术， 将显示画面分为多频道， 可使不同人在同一时间， 使用单一屏幕， 经由各自配戴的快门眼镜来收看不同的频道。
本发明的又一主要目的在于提供一种单屏幕多频同步 2D及 3D影音系 统， 利用 3D显示技术， 将显示画面分为多频道， 可使不同人在同一时间， 使用单一屏幕， 经由各自配戴的快门眼镜来收看不同的频道， 且收看的画 面皆为 3D显示。
依据上述目的， 本发明提供一种单屏幕多频同步 2D及 3D影音系统， 包括： 一多频控制装置， 具有多个频道以及一信号编辑装置， 该信号编辑 装置依据多个频道的 2D 或 3D 影像编辑其播放顺序并产生一通讯协议信 号 ,而通讯协议信号由多个不同形态的影像播放控制方波 (或信号）以及一个 画面更新控制方波 (或信号）所组成，其中该些频道的影像播放由该些不同形 态的影像播放控制方波控制； 一显示器与多频控制装置连接， 并依据信号 编辑装置的播放顺序依序显示至少一 2D或 3D的影像； 一信号发射器， 配 置于显示器中， 用以输出通讯协议信号； 多个快门眼镜， 每一快门眼镜具 有一接收装置， 接收装置用以接收信号发射器所发射的通讯协议信号， 以 控制该些快门眼镜的左镜与右镜的开启或关闭。
经由本发明所提供的设计， 可使有 3D显示功能的显示器， 转变为单 屏幕多频同步的 2D及 3D影音系统， 使普通 3D显示器充分运用该 3D显 示技术， 并可减少家庭购买显示器的支出。 附图说明

由于本发明揭露一种单屏幕多频同步的 2D及 3D影音系统， 特别是利 用一种 3D显示技术的影音系统； 其中所利用到的一些关于画面更新方式、 快门眼镜、 音讯传输、 影像信号传输， 利用现有技术来达成， 故在下述说 明中， 并不作完整描述。 此外， 于下述内文中的图式， 亦并未依据实际的 相关尺寸完整绘制， 其作用仅在表达与本发明特征有关的示意图。
首先， 请参阅图 la至图 lc, 为 3D影像播放的示意图。 首先， 如图 la 所示， 3D显示技术主要是以一个显示器 10来提供一左眼画面 50与一右眼 画面 51 , 并且以非常快速的频率依序交替显示播放左眼画面 50及右眼画 面 51 ; 例如， 如图 lb所示， 是以左图、 右图、 左图、 右图方式依序播放； 因此， 如图 lc所示， 观看者以棵视观看显示器的屏幕时， 会看见左眼画面 50及右眼画面 51重叠的画面。
接着， 请参阅图 2 , 为本发明的 3D影音系统示意图。 如图 2所示， 3D 影像系统包括： 一显示器 10 , 具有一显示屏 101 , 用以显示影像； 一信号 发射器 12配置于显示器 10中，用以播放已经编排好的 3D影像信号以及通 讯协议； 一快门眼镜 30, 具有一接收装置 301 , 用以接收信号发射器 12所 发射的 3D影像信号以及通讯协议， 并且依据通讯协议来控制快门眼镜 30 开关左镜 3001与右镜 3003。 当在观看 3D影像时， 显示器 10的信号发射 器 12会发射出 3D影像信号至显示屏 101 , 并在显示屏 101上交替显示左 眼画面 50及右眼画面 51 ; 同时， 信号发射器 12所发出的通讯协议会被快 门眼镜 30的接收装置 301所接收， 因此， 当显示屏 101上的画面显示为左 眼画面 50时，通讯协议会使快门眼镜 30的左镜 3001开启（此时，右镜 3003 保持关闭状态）； 反之， 当显示屏 101上的画面为显示为右眼画面 51 时， 通讯协议会使快门眼镜 30的右镜 3003开启（此时， 左镜 3001保持关闭状 态）； 通过此种左眼画面 50与右眼画面 51依序交替播放以及通过通讯协议 控制快门眼镜 30的左镜 3001与右镜 3003的开启与关闭的过程，运用人眼 拥有残影的特点， 观看者对画面产生立体感。 再接着， 请参阅图 3a至图 3d, 为本发明的单屏幕多频同步 2D影音系 统显示顺序示意图。 首先， 如图 3a所示， 将前述显示器 10所提供的左眼 画面 50及右眼画面 51更改为在第一频道画面 60显示一个 2D影像的信号 及在第二频道画面 61显示另一个 2D影像的信号， 并以非常快速的频率交 替显示播放第一频道画面 60及第二频道画面 61 , 如图 3b所示； 因此， 当 观看者在棵视观看时， 会看见第一频道画面 60及第二频道画面 61重叠的 画面， 如图 3c所示。 而当多个观看者分别在配戴对应第一频道及第二频道 的快门眼镜之后， 即可通过控制一个快门眼镜的左镜及右镜只在播放第一 频道画面时， 两镜才同时开启（此时， 其它的快门眼镜是关闭状态）； 而当播 放至第二频道时， 则另一快门眼镜的左镜及右镜同时开启 （此时， 其它的 快门眼镜是关闭状态） ； 故当播放第一频道画面时， 则只有快门眼镜的左 镜及右镜同时开启者才看得到第一频道的画面； 而当播放第二频道画面时， 则只有快门眼镜的左镜及右镜同时开启者才看得到第二频道的画面， 如图 3d所示。
再接着，详细说明本发明的单屏幕多频同步 2D影音系统的播放及观看 过程。 请参考图 4 , 为本发明的单屏幕多频同步 2D影音系统示意图。 如图 4所示， 单屏幕多频同步 2D影音系统包括： 一显示器 10 , 具有一显示屏 101 , 用以显示影像； 一信号发射器 12配置于显示器 10中， 用以播放已经 编排好的 2D影音信号以及通讯协议； 一多频控制装置 20 , 以一导线 22与 显示器 10连接 (或可将频控制装置 20内建于显示器 10内）， 多频控制装置 20具有一信号编辑装置 201与一音讯发送装置 203 ; —第一快门眼镜 31 , 具有一接收装置 315 , 用以接收信号发射器 12所发射的 2D影像信号以及 通讯协议， 并且依据通讯协议来使第一快门眼镜 31 同时开关左镜 3101与 右镜 3103 ; —对第一耳机 313 , 配置于第一快门眼镜 31的镜架 311上， 且 此对第一耳机 313接收多频控制装置 20的音讯发送装置 203所发射的第一 声音信号 2031 ; —第二快门眼镜 33 , 具有一接收装置 335 , 用以接收信号 发射器 12所发射的 2D影像信号以及通讯协议， 并且依据通讯协议来使第 二快门眼镜 33 同时开关左镜 3301与右镜 3303 ; —对第二耳机 333 , 配置 于第二快门眼镜 33的镜架 331上，且此对第二耳机 333接收多频控制装置 20的音讯发送装置 203所发射的第二声音信号 2033。 此外， 于第一快门眼 镜 31 及第二快门眼镜 33 的侧边上， 分别配置有多个频道切换键 40 以及 3D影像切换键 42。在多人观看显示器 10的多个频道时，在显示器 10的显 示屏 101上， 交替显示第一频道画面 60及第二频道画面 61的影音信号， 且当显示画面为第一频道画面 60时，显示器 10的信号发射器 12会发射出 第一频道影像信号以及通讯协议， 而第一快门眼镜 31接收到通讯协议时， 第一快门眼镜 31 的左镜 3101及右镜 3103会同时开启（此时， 第二快门眼 镜 33也会接收到通讯协议， 而通讯协议的信号使得第二快门眼镜 33的左 镜 3301及右镜 3303会同时关闭）； 当显示画面播放至第二频道画面 61时， 显示器 10的信号发射器 12会发射出第二频道影像信号以及通讯协议， 而 第二快门眼镜 33接收到通讯协议时，第二快门眼镜 33的左镜 3301及右镜 3303会同时开启（此时， 第一快门眼镜 31也会接收到通讯协议， 而通讯协 议的信号使得第一快门眼镜 31 的左镜 3101及右镜 3103会同时关闭）； 而 此时， 多频控制装置 20 内的音讯发送装置 203会分别将第一频道画面 60 的第一声音信号 2031传送至第一快门眼镜 31 ; 将第二频道画面 61所对应 的第二声音信号 2033 , 传送至第二快门眼镜 33 , 观看者可通过快门眼镜上 的耳机来聆听相对应的频道声音。 本发明的音讯传输最佳实施方式为无线 传输， 例如： 蓝牙、 红外线等...， 但亦可以用有线传输的方式， 如： 音源 线、 电缆等 ...， 本发明对于音讯传输的方式并不加以限定。
接着， 请参阅图 5 , 为本发明的快门眼镜示意图。 如图 5所示， 首先， 以画面更新频率为 120hz的显示器为例， 在此更新频率的规格下， 显示器 可提供单一个人观看一部 3D 影像的频道， 或者双人同时观看不同的两个 2D影像的频道； 若以画面更新频率为 240hz的显示器为例， 在此更新频率 的规格下，显示器可提供双人同时观看不同的两个 3D影像的频道，或者四 人同时观看不同的 2D影像的频道， 或者同时给与单人观看一个 3D影像的 频道及双人观看不同的 2D影像的频道； 因此， 当显示器画面更新频率越高 时， 可同时观看者亦越多。
当显示器需要提供两个频道的影像两个观看者同时观赏时， 会先于多 频控制装置 20 上设置要观看的两个频道的影像 (例如： 先转到随一频道， 再按第一频道键， 多频控制装置 20便会将该频道记录为第一频道； 第二频 道亦相同）， 此时， 多频控制装置 20 也依据设定观看频道的数量完成通讯 协议的设定； 接着， 显示器 10中的信号发射器 12会依据多频控制装置 20 的设定， 依序交替显示播放第一频道的影像及第二频道的影像， 同时， 将 通讯协议传送出去。 此时， 每一个观赏者分别戴上快门眼镜后， 可由操作 来选取所要观赏的频道； 例如： 当快门眼镜启动后， 快门眼镜的接收装置 即开始接收到显示器 10中的信号发射器 12的信号； 此时， 每一个戴着快 门眼镜的观赏者可通过按取快门眼镜上的多个频道切换键 40 来选择所想 观赏的频道； 例如： 要以第一快门眼镜 31观看第一频道的 2D影像时， 即 可按取频道切换键 40 , 当第一快门眼镜 31 切换到第一频道后， 即会在显 示器 10中的信号发射器 12在播放至第一频道的影像时， 通讯协议会将第 一快门眼镜 31的左镜 3101及右镜 3103会同时开启， 因此， 戴着第一快门 眼镜 31的观赏者就能看到第一频道的 2D影像。
若当此观赏者想要观看第二频道的 2D影像时，其只要再按取频道切换 键 40 , 当第一快门眼镜 31切换到第二频道后， 第一快门眼镜 31即依据第 二频道的通讯协议来同时开启或关闭左镜 3101 及右镜 3103 ; 故当在显示 器 10中的信号发射器 12在播放至第二频道的影像时， 通讯协议会将第一 快门眼镜 31的左镜 3101及右镜 3103会同时开启， 因此， 戴着第一快门眼 镜 31的观赏者就能看到第二频道的 2D影像。
再者，若观看频道为一 3D影像时， 则观赏者只需再按下第一快门眼镜 31上的 3D影像切换键 42 , 画面即转换成 3D影像， 此时， 第一快门眼镜 31即会依据 3D影像的通讯协议来开启或关闭左镜 3101及右镜 3103。快门 眼镜的左镜及右镜的开启或关闭， 是由显示器 10的信号发射器 12所发射 的通讯协议来控制， 例如： 2 D画面会控制左镜及右镜同时开启或关闭； 而 3D 画面会控制左镜及右镜与对应的左眼、 右眼画面来做开启或关闭的动 作。
本发明的单屏幕多频同步 2D及 3D影音系统通过配置一个多频控制装 置 20来改变信号发射器 12所发射的通讯协议信号， 使得快门眼镜的左镜 及右镜， 在对应的频道才会同时开启（如第一频道）， 而在另一频道 (如第二 频道)会同时关闭。 此外， 也特别要强调， 前述的说明， 主要在叙述单屏幕 多频同步 2 D影音系统的操作过程， 并未以显示器的画面更新频率为限制。 如前所述， 当显示器画面更新频率越高时， 可同时观看者亦越多。
接着， 请参阅图 6 , 为本发明的单屏幕多频同步 2D及 3D影音系统的 通讯协议信号示意图。 首先， 如图 6 所示， 方波信号的高 （high ) 状态的 数量及时间间隔分为三种控制方波型态（以 A、 B、 C代表）， 其中， 控制方 波型态 A的方波信号是由三个高 （high ) 状态的方波所组成， 各高状态的 方波宽度为 25us(lms=1000us )、 而方波间的低状态时间间距亦为 25us , 因 此控制方波型态 A的第一时间总长为 125us。 控制方波型态 B的方波信号 是由两个高状态所组成， 各高状态的方波宽度为 25us、 而方波间的低状态 的时间间距为 75us, 因此型态 B的第二控制方波时间总长为 125us。 控制 方波型态 C的方波信号是由两个高状态所组成， 各高状态的方波宽度及方 波间的低状态时间间距均为 25us , 因此型态 C的第三控制方波时间总长为 75us。 其中， 型态 A代表显示器 10需显示第一频道画面 60 , 型态 B代表 显示器 10需显示第二频道画面 61 , 而型态 C代表各频道画面结束， 需进 行下一个画面的更新。
以图 6的时间轴为例， 在显示器画面更新频率为 120hz的规格时， 每 一个显示画面加上更新至下一显示画面的时间大约为 8.33ms。如图 6所示， 在一开始， 快门眼镜检测到信号发射器 12 所发射出的通讯协议的型态 A 时； 此时， 显示器 10会显示第一频道画面 60 , 这时， 与第一频道画面 60 对应的第一快门眼镜 31将左镜 3101及右镜 3103同时打开， 而与第二频道 画面 61对应的第二快门眼镜 33将左镜 3301及右镜 3303同时关闭， 因此 只有配戴第一快门眼镜 31的人可以看到画面。 接着， 当快门眼镜检测到信 号发射器 12所发射出的通讯协议的型态 C时；此时表示画面将进入更新状 态， 因此所有快门眼镜会因此全部关闭。 再接着， 当快门眼镜检测到信号 发射器 12所发射出的通讯协议的型态 B时； 此时表示画面已更新完毕， 显 示器 10将显示第二频道画面 61 , 这时， 与第二频道画面 61对应的第二快 门眼镜 33将左镜 3301及右镜 3303同时打开， 而与第一频道画面 60对应 的第一快门眼镜 31将左镜 3101及右镜 3103同时关闭， 因此只有配戴第二 快门眼镜 33的人可以看到画面。 再接着， 快门眼镜会再检测到信号发射器 12所发射出的通讯协议的型态 C, 此时又表示画面将再进入更新状态， 因 此所有快门眼镜全部关闭。 的后便再回复到检测到型态 A, 以此循环。
各动作 (开始显示、停止显示、 更新完毕)其开始时间皆为各控制方波型 态 (A、 B、 C)的方波信号末端； 即表示检测到型态 A经过 125us后， 显示 器 10才开始显示第一频道画面 60 ,之后经过 1.9ms加上型态 C的 75us后（共 1.975ms),画面开始转换，再经过 6.23ms加上型态 B 125us后（共 6.355ms), 显示器 10才开始显示第二频道画面 61 , 以此再回到型态 C, 再至型态 A 循环。
而此方波信号检测方式亦可运用在 3D显示，如图 6所示，在原显示第 一频道画面 60的时段， 改为显示左眼画面 50 , 而此时一快门眼镜 30的左 镜 3001会开启， 而右镜 3003会关闭， 接着， 时段来到画面更新时间时， 左镜 3001与右镜 3003会同时关闭。 时段来到原显示第二频道画面 61的时 段， 改为显示右眼画面 51 , 而此时快门眼镜 30的左镜 3001会关闭， 而右 镜 3003会开启， 然后时段会再进入画面更新时间， 此时左镜 3001与右镜 3003会再同时关闭， 接着便回到左眼画面循环。
在此要强调的是， 本时间轴所表示的各控制方波型态， 仅为方便解说 本发明所标示的时间， 详细控制方波型态可依各厂牌的显示器或快门眼镜 而有所不同， 故本发明并不加以限定。
接着， 请参阅图 7 , 为本发明的 240hz频率画面显示方式示意图。 如图 7所示，在显示器为 240hz频率的规格时，显示器可双人同时观看不同的两 个 3D影像的频道， 或者四人同时观看不同的 2D影像的频道， 或者同时给 与单人观看一个 3D影像的频道及双人观看不同的 2D影像的频道。 如 T1 时间轴所示， 此 T1时间轴表示四人同时观看不同的 2D影像的频道， 画面 显示方式为，第一频道 (2D)→画面更新→第二频道 (2D)→画面更新→第三频 it(2D)→®面更新→第四频道 (20)→画面更新→第一频道 (2D) →→循环； 而亦如上述的方式， 在第一频道 (2D)播放时， 只有对应的快门眼镜的左镜 跟右镜会同时开启， 其余无对应的快门眼镜会关闭， 依此类推。
接着， 如 T2时间轴所示， 此 T2时间轴表示双人同时观看不同的两个 3D影像的频道， 画面显示方式为， 第一频道左眼画面（3D)→画面更新→第 二频道左眼画面（30)→画面更新→第一频道右眼画面（30)→画面更新→第 二频道右眼画面（3D)→画面更新→第一频道左眼画面（3D) →→循环； 而亦 如上述的方式， 在第一频道左眼画面（3D)播放时， 只有对应的快门眼镜的 工 、 - 再接着， 如 T3时间轴所示， 此 T3时间轴表示同时给与单人观看一个 3D影像的频道及双人观看不同的 2D影像的频道， 画面显示方式为， 第一 频道左眼画面（3D)→画面更新→第二频道 (2D)→画面更新→第一频道右眼 画面（30)→画面更新→第三频道 (20)→画面更新→第一频道左眼画面（3D) →→循环； 在第一频道左眼画面（3D)播放时， 只有对应的快门眼镜的左镜 会开启， 其余无对应的快门眼镜会关闭， 而在第二频道 （2D)播放时， 只有 对应的快门眼镜的左镜跟右镜会同时开启，其余无对应的快门眼镜会关闭， 第三频道亦同； 因此由此可知， 各不同频道或左、 右画面是以交错形式循 环播放， 以达到各频道画面更新的间隔较为平均。 而因在 240hz频率的规 格下， 因频道增多， 因此在图 6 所述的方波信号的高 （high ) 状态亦会随 频道增多而增加不同的型态， 以辨别不同的显示画面， 如： 四个频道就会 有四个不同的型态的方波信号作为该频道画面的开端， 但仍以一相同型态 的方波信号来做为画面的结尾 (画面更新的开端；)。
虽然本发明以前述的较佳实施例揭露如上， 然其并非用以限定本发明， 任何熟习相像技艺者， 在不脱离本发明的精神和范围内， 当可作些许的更 动与润饰， 因此本发明的专利保护范围须视本说明书所附的申请专利范围 所界定者为准。
