Description

多视点3D显示屏、多视点3D显示终端
本申请要求在2019年12月05日提交中国知识产权局、申请号为201911231427.1、发明名称为“多视点裸眼3D显示屏、多视点裸眼3D显示终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及3D影像领域，例如涉及多视点3D显示屏、多视点3D显示终端。
背景技术
在常规的3D显示器的构造中，仅仅是在2D显示面板一侧或两侧设置光栅来提供3D显示效果，所以关于像素和子像素以及分辨率的定义均沿用2D显示器的理念。这带来了分辨率下降和渲染计算量激增的两难问题。
由于2D显示面板的分辨率总数为定值，因此分辨率会急剧下降，例如列分辨率降为原分辨率的1/N。由于多视点显示器的像素排布，这还会导致水平与竖直方向分辨率降低倍数不同。
如果要维持高清晰度的显示，在提供高清晰度例如N倍于2D显示器件的N视点3D显示器件的情况下，需要占用的终端到显示器的传输带宽也以N倍倍增，导致信号传输量太大。而且，对于这种N倍的高分辨率图像的像素级渲染会严重占用终端或显示器自身的计算资源，造成性能大幅下降。
而且，由于3D图像或视频的传输和显示以2D显示面板为基础，还可能存在多次格式调整和图像或视频显示适配的问题。这一方面可能会造成渲染计算量的进一步增加，另一方面可能会影响3D图像或视频的显示效果。
本背景技术仅为了便于了解本领域的相关技术，并不视作对现有技术的承认。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。
在本公开的一些实施例中，本公开提供了一种多视点3D显示屏(例如：多视点裸眼3D显示屏)，包括：
显示面板，包括多个复合像素，多个复合像素中的每个复合像素包括多个复合子像素，多个复合子像素中的每个复合子像素由对应于i个视点的i个同色子像素构成，其中i≥3；和
并列设置在多个复合像素上的多个光栅，多个光栅中的每个光栅包括第一斜边和第二斜边，多个光栅的每个光栅倾斜覆盖在多个复合像素上以使第一斜边和第二斜边与复合像素的每个复合子像素相交以限定出倾角；
其中，多个复合像素中的每个复合子像素中，与光栅的第一斜边相交或临近的子像素构成第一端子像素，与光栅的第二斜边相交或临近的子像素构成第二端子像素；
光栅的倾角被设置为使得：沿光栅的第一斜边的延伸方向，至少部分相邻复合像素中与光栅具有最大重叠面积的第一端子像素的颜色不相同。
参照图1A、图7A至图7C，在本公开的一些实施例中，提供了一种3D显示屏100，包括显示面板110，显示面板110上包括m×n个复合像素CP并因此限定出m×n的显示分辨率；显示屏100还包括覆盖在m×n个复合像素CP上的多个光栅120；复合像素CP包括多行复合子像素CSP，每个复合子像素由对应于i个视点的i个同色的子像素P构成，其中i≥3；光栅120的光栅边缘121与每个复合像素CP中的每个行复合子像素CSP相交；每个复合像素CP中，临近光栅边缘121的子像素P组成复合像素的起始的视点像素 BWP或相邻的复合像素CP中的终止的视点像素EWP；光栅边缘121的倾角θ被配置为使得：沿光栅边缘121的延伸方向，复合像素CP中起始的视点像素的主颜色按照每个复合子像素CSP的颜色依次交替。
其中，相邻的光栅边缘121限定出光栅120，起始的视点像素BWP的主颜色定义为：起始的视点像素中的子像素P与光栅120重叠面积最大的子像素的颜色。
光栅边缘121包括第一斜边1211和第二斜边1212，第一斜边1211和第二斜边1212倾斜覆盖在多个复合像素CP上，第一斜边1211和第二斜边1212在复合像素CP所在平面上的投影与每个复合子像素CSP相交限定出倾角。即，第一斜边1211和第二斜边1212与每个复合子像素CSP的延伸方向不平行。在多个复合像素CP中的每个复合子像素CSP中，与光栅120的第一斜边1211相交或临近的子像素P构成第一端子像素，与光栅的第二斜边1212相交或临近的子像素P构成第二端子像素；根据上述的实施方式，第一端子像素可以定义为起始的视点像素BWP，第二端子像素可以定义为终止的视点像素EWP。上述的“相交”的含义并非仅仅包括空间上同处于一个平面上的相交，由于光栅边缘121与复合子像素CSP常常不处于同一个平面上，这里的“相交”是指，复合子像素CSP与第一斜边1211或者第二斜边1212不在一个平面上，将第一斜边1211和第二斜边1212投影到复合子像素CSP所在的平面上，投影与复合子像素CSP在同一个平面内相交。
第一斜边1211和第二斜边1212倾斜设置，倾斜的角度通过倾角来控制，倾角的参考边以显示面板110的下边缘为准。
光栅120的倾角被设置为使得：沿光栅的第一斜边1211的延伸方向，至少部分相邻复合像素CP中与光栅120具有最大重叠面积的第一端子像素的颜色不相同。
如图所示，光栅120下具有复合像素CP，复合像素CP中包括多个对应视点的视点像素WP，根据需要点亮的视点，相应选择和视点对应的视点像素WP，在本实施例中，为了实现视点像素WP显示不同的颜色，从而在整体视觉效果下显示不同的画面，视点像素WP包括多个子像素P，各个子像素P具有不同的显示颜色(例如红色、绿色、蓝色)和不同的显示亮度(通过电路控制驱动电压或者驱动电流进行控制)，在本实施例中，子像素P按照同色进行同行排列，每行同色的子像素P形成复合子像素CSP，多行同色的子像素P形成复合像素CP。为了实现3D效果，根据用户眼部所在的位置，获取左右眼接收到图像的视点，例如，左眼在2视点，右眼在7视点，对应的，在显示屏中，m×n个复合像素CP中对应2视点的视点像素WP，各自对应显示左眼图像，m×n个复合像素CP中对应7视点的视点像素WP，各自对应显示右眼图像，从而实现3D效果。
在本实施例中，每个复合子像素CSP中，对应每个视点，具有相应的子像素P，行方 向上，子像素P的颜色相同；由于视点的分布是按照行方向上排布的，这样，在用户的眼部移动时，对应视点在变化过程中，从而需要变化渲染不同的子像素P，由于同色的子像素P同行排列，所以能够避免由于视觉暂留带来的串色问题；还有，由于光栅的折射，有可能会在相邻的视点位置看见当前显示子像素P的一部分，而通过同色、同行排列，即使当前显示子像素P的一部分被看见，也不会出现混色的问题。
在本实施例中，相邻的光栅边缘121限定出光栅120，出于改善摩尔纹的问题，光栅120常常需要倾斜设置，由于光栅120的光栅边缘121倾斜设置，一般会切割子像素P，被切割的子像素P即可能在光栅边缘121左面的视点像素WP对应的视点位置被看见，也可能被光栅边缘121右面的视点像素WP对应的视点位置被看见，但是由于在单独的视点位置上，仅能看见被切割的子像素P的部分。即，在复合像素CP中起始的视点像素BWP对应的多个子像素P(起始的子像素)的面积不一致，总会出现某个子像素的显示面积(或者可定义为在观看视点被看见的面积)在多个子像素P中占比最大。通过调整光栅边缘121的倾斜角度，可以调整各个复合像素CP中起始的视点像素BWP中的占比面积最大子像素的颜色出现的顺序，当然也可调整各个子像素P的排布位置与顺序来调整占比面积最大的子像素的颜色(此颜色可定义为主颜色)出现的顺序，当然，这种调整子像素P的排布位置与顺序的方需要较大的更改现有的制备显示面板的工艺步骤。一般地，可以采用，调整光栅边缘121的倾角的方式来调整各个复合像素CP中起始的视点像素BWP中的占比面积最大子像素的颜色出现的顺序，即，调整光栅边缘121的倾角的方式来调整各个复合像素CP中第一端子像素中与光栅120具有最大重叠面积子像素的颜色出现的顺序。发明人在实施方案中发现，如果复合像素CP中起始的视点像素BWP中的占比面积最大子像素的颜色总是较大概率连续出现，或者占比出现概率较大，则会影响初始的视点像素BWP的显示效果，例如，当总是连续红色占比最大，或者总体红色占比最大，则会出现泛红晕的情况，当然对于其他颜色也是如此。
在上述的实施例中，沿着第一斜边1211的延伸方向，相邻的复合像素CP中与光栅120具有最大重叠面积的第一端子像素，即具有最大重叠面积的初始的视点像素BWP不相同，或者按照颜色顺序交替出现，其中，颜色顺序例如可以按照R(红色)-G(绿色)-B(蓝色)的顺序。从而，在第一斜边1211附近观看到最大重叠面积的子像素，不会出现总是同样的色彩，出现泛红晕的情况。
在一些实施例中，相邻的光栅120并列设置，边缘不留间隙，当前的光栅120的第二斜边1212会和相邻的光栅120的第一斜边1211重合，类似地，当前的光栅120的第一斜边1211会和另一个相邻的光栅120的第二斜边1212重合，需要说明的是上述的重合可以 是相邻的光栅120同处一个平面时，边缘的空间重合；当然，如果相邻的光栅120不处于同一个平面，例如处于相互平行的平面上时，上述的重合指代的是投影到某一个光栅120所在平面时，边缘的投影重合，或者边缘的投影与处于投影平面上的光栅的边缘重合。
在一些实施例中，光栅120的倾角还可被设置为使得：沿光栅120的第二斜边1212的延伸方向，至少部分相邻复合像素CP中与光栅120具有最大重叠面积的第二端子像素的颜色不相同。
在本实施例中，显示面板110可以采用制备LCD的技术进行制备，也可采用制备Micro Led的技术进行制备，一般地，为了简化制备工艺，子像素P的位置常常会规律性的重复排列，这样，有效提高了制备的效率简化了制备的过程。在本实施例中，也可将复合像素CP中每个复合子像素CSP中的子像素P进行规律重复性的排列，即，可设置子像素P之间的间距保持不变，例如同行的子像素P之间的间距保持一致，列方向上子像素P的行距保持一致；相邻行的之间子像素P的位置可以对齐，也可出于其他的考虑相互位置错开。在本实施例中，可以选择将相邻行的之间的子像素P的位置对齐，可以有效简化制备工艺，同时为设置光栅边缘121的倾角设置提供了稳定条件。
在本实施例中，沿着光栅边缘121，每个复合像素CP的起始的视点像素BWP(图7中斜纹填充的子像素P组成)的主颜色依次交替，使得在光栅边缘121的主颜色分量依次交替，由于在光栅边缘121附近的视点像素的对应视点的关系理论上大致相同(个别复合像素CP有可能有安装误差，后期可校准)，所以在显示整幅画面，需要点亮光栅边缘121附近的视点像素时，避免了光栅边缘的每个复合像素CP中的显示颜色面积占比相同，从而出现泛红晕(或者其他颜色)，而是，轮流让不同颜色的子像素P的面积占比为最大，例如，对应行方向上第一条光栅边缘121，与之相交的复合像素CP沿着列方向上(沿着光栅边缘121的延伸方向上)，起始的视点像素BWP的主颜色依次变化，例如，第一个复合像素CP中的BWP的蓝色占比面积最大，第二个复合像素CP中的BWP的红色占比面积最大，第三个复合像素CP中的BWP的绿色占比面积最大，第四个复合像素CP中的BWP的蓝色占比面积最大，依次交替变化，从而避免了泛红晕(或者其他颜色)或者同色亮线的问题。
为了便于显示面板上Color Filter的制作，子像素P，常常是阵列排布的，在2D显示中，同列或者同行的多个子像素P，组成一个像素点，而在3D显示中，由于光栅的存在，为了避免摩尔纹，光栅常常需要倾斜设置，对应的视点像素中的多个子像素，几乎不能按照同行、或者同列的方式进行排布，所以需要重新定义视点像素中子像素的排布关系，通过限定复合像素CP起始的视点像素BWP所对应的子像素P，即能限定整个CP中视点像 素BWP与复合子像素CSP中的同色的子像素P之间的关系，起始的视点像素的定义为：
如果光栅边缘121未与子像素P相交，沿着光栅边缘121的倾斜方向，第一个子像素P属于起始的视点像素BWP；
如果光栅边缘121与子像素P相交，相交的子像素P中，沿着光栅边缘121的倾斜方向剩下的面积大于或等于阈值时，则相交的子像素P属于起始的视点像素BWP，否则相交的子像素沿着光栅边缘121的倾斜方向的下一个子像素P属于起始的视点像素BWP。参考图7C，光栅边缘121向右倾斜，光栅边缘121与三个复合子像素CSP相交，其中，由于子像素P之间存在一定宽度的黑矩阵，光栅边缘121与复合子像素CSP相交时，可能不会与子像素P相交；当不相交时，光栅边缘121右边的第一个子像素划分到复合像素CP中的起始的复合像素BWP中；当光栅边缘121与子像素P相交时，子像素中，光栅边缘121右面的面积占到子像素P的面积的一半或者是其他阈值以上时，则相交的子像素属于复合像素CP中的起始的视点像素BWP中；当光栅边缘121与子像素P相交时，子像素P中，光栅边缘121右面的面积小于子像素P的面积的一半或者是其他阈值时，则相交的子像素不属于复合像素CP中的起始的视点像素BWP中，而是往右第二个子像素P属于复合像素CP中的起始的视点像素BWP，而相交的子像素P属于相邻的复合像素CP中的终止的视点像素EWP。上述的占比阈值还可设置成三分之二或者其他值。
终止的视点(子)像素的定义为：
在临近光栅边缘121的视点子像素P中，没有被归入起始的视点(子)像素BWP的，属于终止的视点(子)像素EWP。
在本实施例的一些方案中，复合像素CP的长宽方向上的尺寸大致相等。这样能够有效减少摩尔纹，并且制作工艺简单。
在一些实施例中，每个复合像素CP包括多个复合子像素，每个复合子像素由对应于i个视点的i个同色子像素构成，i≥3。在图1A所示的实施例中，i＝6，但可以想到i为其他数值。在所示的实施例中，多视点3D显示屏可相应地具有i(i＝6)个视点(V1-V6)，但可以想到可以相应地具有更多或更少个视点。
结合参考图1A和图4A，在所示的实施例中，每个复合像素包括三个复合子像素，并且每个复合子像素由对应于6视点(i＝6)的6个同色子像素构成。三个复合子像素分别对应于三种颜色，即红(R)、绿(G)和蓝(B)。也就是说，每个复合像素的三个复合子像素分别具有6个红色、6个绿色或6个蓝色的子像素。
在图1A和图4A所示的实施例中，复合像素400中的复合子像素410、420、430平行布置。每个复合子像素410、420、430包括呈单行形式的子像素411、421、431。但可以 想到，复合像素中的复合子像素不同排布方式或复合子像素中的子像素的不同排布形式。
在图4B所示的实施例中，复合像素400中的复合子像素470、480、490阵列布置。例如，每个复合子像素470、480、490包括呈阵列2×3形式的子像素471、481、491。
如图1A所示，本实施例的一些方案中，视点数量为6个，每个复合像素CP中，设有三行复合子像素CSP，每个视点像素由分别来自三行复合子像素CSP中的3个子像素P组成。
在本实施例中的一些方案中，光栅边缘121的倾角θ满足如下公式，tan(θ)＝±3/(i×k)，其中k不被3整除，i为视点的个数。其中，θ逆时针偏转为正，顺时针偏转为负。
本实施例中的显示屏中，能够根据眼部定位装置获取到的眼部所在位置相关联的视点信息，调整点亮的视点像素WP，由于在每个复合像素中，视点像素WP与视点之间的关系已经预先固定，即在每个复合像素中通过简单的移位即可进行渲染，而不需根据眼部位置计算哪个子像素需要点亮，从而增加了计算量，在一些现有的方案中，计算的过程还会涉及取整的过程，而本实施例中的方案避免了这个问题，仅需移位，不需要计算取整的过程，从而增加了渲染的效率。
在本实施例中的一些方案中，光栅边缘的倾角θ满足tan(θ)＝±1\8。
参考图8A、图8B，进一步对光栅边缘121的倾角θ进行说明。复合像素CP中的子像素P阵列排布，相邻的同行的子像素P间隔相同，相邻的同列的子像素P的间隔也相同。相邻的四个子像素P之间的中间点为角点，为了直观说明问题，某个复合像素CP区域附近，设定光栅边缘121的起始点位于复合像素CP最左上的角点，由于常规像素点包括三种颜色，进一步设定本实施例中的复合像素CP具有3行同色复合子像素CSP，光栅边缘121与下一行子像素P相交时，正好也穿过角点，则可保证光栅边缘121规律性的穿过角点，设置相邻被光栅边缘121穿过的角点为PA、PB，PA与PB之间的相交情况将要，规律性的在下一个相邻的角点之间出现，如果PB正好位于下一个复合像素CP的起始行上，则光栅边缘121穿过复合像素CP的情况则会在每个复合像素CP中重复出现，例如，光栅边缘121切割子像素P后，右侧剩下的面积最大的子像素，总是会重复出现，例如，会出现总是红色的子像素被切割后占比最大，这样，在沿用上述的视点像素WP的定义时，则会出现，在起始的视点像素BWP中，总是同色的子像素的占比面积最大，这样就会出现泛红晕(或者其他颜色)的情况。同样的，如果PB正好位于下T个复合像素CP的起始行上(T大于1)，也会间隔性地出现上述的问题，让起始的视点像素BWP中某个颜色的占比总是会大于其他颜色的占比，同样会带来上述的显示问题。
由此，本实施例设定相邻的角点之间的切割规律不在3个复合子像素CSP之间重复， 也不再3的倍数个复合子像素CSP之间重复。
为了更加直观的表达上述的设定，参照图8A、图8B，进行公示推导如下：
具有i个视点像素WP的复合像素的宽尺寸为W＝i×(w1+w2)，w1为子像素P宽尺寸，w2为子像素P行方向上的间距；
高尺寸为H＝3×(h1+h2)，h1为子像素P高尺寸，h2为子像素列方向上的间距；
由于具有i个视点像素WP的复合像素的宽尺寸与高尺寸一致，则有：W＝i×(w1+w2)＝H＝3×(h1+h2)；
相邻的角点PA、PB之间，具有k行复合子像素CSP，k不被3整除；则光栅边缘的倾角θ满足：tan(θ)＝(w1+w2)/k×(h1+h2)/；根据上述宽尺寸与高尺寸一致的关系，上式可简化为，tan(θ)＝(3×(h1+h2)/i)/k×(h1+h2)＝3/(i×k)；
综上，光栅边缘121的倾角θ满足：tan(θ)＝3/(i×k)，i为视点的个数，k为不被3整除的整数，如图8A所示，k＝4，i＝6，则tan(θ)＝3/24＝1/8，第一个复合像素CP中，蓝色的子像素切割后占比面积最大，第二个复合像素CP中，红色的子像素切割后占比面积最大。依次循环下去。
如图8B所示，k＝5，i＝6，则tan(θ)＝1/10。
在本实施例中的一些方案中，多视点3D显示屏为Micro-LED显示面板。
在本实施例中的一些方案中，与同一光栅边缘121相交的复合像素中的起始的视点像素与视点的对应关系相同；和\或，与同一光栅边缘121相交的复合像素中的终止的视点像素与视点的对应关系相同。例如，与同一光栅边缘121相交的复合像素CP中起始的视点像素BWP对应的视点都为视点1，与同一光栅边缘121相交的复合像素CP中终止的视点像素EWP对应的视点都为视点6，当然，实际使用中，由于实际尺寸关系，需要经过校正视点关系，与同一光栅边缘121相交的个别复合像素CP中的起始的视点像素BWP对应视点6，相邻的复合像素CP的终止的视点像素EWP对应视点5。本公开中，还可为显示屏100，设置有存储有视点像素与视点之间关系的信息，从而在3D渲染处理器在图像渲染过程中，实时的获取对应关系，从而对子像素P进行渲染。
在本公开的另外的实施例中，还提供了一种多视点3D显示终端1000，包括了上述的3D显示屏100。使得多视点3D显示终端显示3D效果。上述的多视点3D显示终端1000可被构造为多视点3D显示终端或者多视点3D显示装置。
在一些实施例中，多视点3D显示终端1000，还包括至少一个3D处理装置130，3D处理装置130配置为基于3D视频信号的图像生成对应于全部视点或预定的视点的多个图像并依据所生成的多个图像渲染每个复合像素中对应的视点子像素。
在一些实施例中，3D处理装置130还配置为根据当前被渲染的视点子像素对应的视点位置，和下一帧被渲染的视点子像素对应的下一视点位置，对复合像素中的视点子像素进行移位渲染。参考图9所示，当前渲染视点V2，下一帧渲染视点V6，通过移位，将数据信号移位四个信号，即能将V2显示的画面显示到视点V6对应的位置。
在一些实施例中，至少一个3D处理装置130配置为基于两幅图像之一渲染每个复合子像素中至少一个子像素并基于两幅图像中另一幅渲染每个复合子像素中至少另一个子像素。
在另外的一些实施例中，至少一个3D处理装置130配置为基于复合图像渲染每个复合子像素中至少两个子像素。
图1A示出了本公开一个实施例提供的多视点3D显示终端1000的结构示意图。参考图1A，在本公开一个实施例中提供了一种多视点3D显示终端1000，其可包括多视点3D显示屏100、至少一个3D处理装置130和用于接收3D视频信号的视频帧的视频信号接口140。
如图1A所示，多视点3D显示屏100包括m列n行个复合像素并因此限定出m×n的显示分辨率。
在一些实施例中，例如图1A-1C所示，多视点3D显示终端1000可设置有单个3D处理装置130。该单个3D处理装置130同时处理对3D显示屏100的每个复合像素的每个复合子像素的渲染。
在另一些实施例中，例如图6所示，多视点3D显示终端1000可设置有至少两个3D处理装置130，它们并行、串行或串并行结合地处理对3D显示屏110的每个复合像素的每个复合子像素的渲染。
本领域技术人员将明白，上述至少两个3D处理装置可以有其他的方式分配且并行处理3D显示屏100的多行多列复合像素或复合子像素，这落入本发明的范围内。
在一些实施例中，至少一个3D处理装置130还可以选择性地包括缓存器131，以便缓存所接收到的视频帧。
在一些实施例中，至少一个3D处理装置为FPGA或ASIC芯片或FPGA或ASIC芯片组。
继续参考图1A，多视点3D显示终端1000还可包括通过视频信号接口140通讯连接至至少一个3D处理装置130的处理器101。在本文所示的一些实施例中，处理器101被包括在计算机或智能终端、如移动终端中或作为其处理器单元。但是可以想到，在一些实施例中，处理器101可以设置在多视点3D显示终端的外部，例如该多视点3D显示终端可 以为外接3D处理装置的非智能的3D电视。
为简单起见，下文中的多视点3D显示终端1000的示例性实施例内部包括处理器。进而，视频信号接口140构造为连接处理器101和3D处理装置130的内部接口，参考图2和图3所示的以移动终端方式实施的多视点3D显示终端200可更明确该结构。在本发明的一些实施例中，作为多视点3D显示终端200的内部接口的视频信号接口140可以为MIPI、mini-MIPI接口、LVDS接口、min-LVDS接口或Display Port接口。在一些实施例中，如图1A所示，多视点3D显示终端1000的处理器101还可包括寄存器102。寄存器102可用与暂存指令、数据和地址。
在一些实施例中，多视点3D显示终端1000还可包括用于获取实时眼部定位数据的眼部定位装置或眼部定位数据接口，从而3D处理装置130可以基于眼部定位数据渲染复合像素(复合子像素)中的相应子像素。例如图1B所示的实施例中，多视点3D显示终端1000还包括通讯连接至3D处理装置130的眼部定位装置150,由此3D处理装置130可以直接接收眼部定位数据。在图1C所示的实施例中，眼部定位装置(未示出)例如可以直接连接处理器101，而3D处理装置130经由眼部定位数据接口151从处理器101获得眼部定位数据。在另一些实施例中，眼部定位装置可同时连接处理器和3D处理装置，这一方面3D处理装置130可以直接从眼部定位装置获取眼部定位数据，另一方面可以使得眼部定位装置获取的其他信息可以被处理器处理。
结合参考图1A-C和图5A-E，描述本公开一些实施例的多视点3D显示终端内的3D视频信号传输和显示。在所示的实施例中，该显示屏100可以限定出6个视点V1-V6，用户的眼睛在每个视点(空间位置)可看到多视点3D显示屏100的显示面板中每个复合像素的复合子像素中相应的子像素的显示。用户的双眼在不同的视点看到的两个不同画面形成视差，在大脑中合成3D的画面。
在本公开的一些实施例中，3D处理装置130通过例如作为内部接口的视频信号接口140从处理器101接收例如为解压缩的3D视频信号的视频帧。每个视频帧可包含具有m×n分辨率的两幅图像或者包含具有2m×n或m×2n分辨率的复合图像，或者由其构成。
在一些实施例中，两幅图像或复合图像可以包括不同类型的图像以及可以呈每个种排布形式。
如图5A所示，3D视频信号的视频帧包含并列格式的具有m×n分辨率的两幅图像501、502或由其构成。在一些实施例中，两幅图像可以分别为左眼视差图像和右眼视差图像。在一些实施例中，两幅图像可以分别为渲染色彩图像和景深图像。
如图5B所示，3D视频信号的视频帧包含上下格式的具有m×n分辨率的两幅图像 503、504或由其构成。在一些实施例中，两幅图像可以分别为左眼视差图像和右眼视差图像。在一些实施例中，两幅图像可以分别为渲染色彩图像和景深图像。
如图5C所示，3D视频信号的视频帧包含左右交织格式的具有2m×n分辨率的复合图像505。在一些实施例中，复合图像可以为左右交织的左眼和右眼视差复合图像、左右交织的渲染色彩和景深复合图像。
如图5D所示，3D视频信号的视频帧包含上下交织格式的具有m×2n分辨率的复合图像506。在一些实施例中，复合图像可以为上下交织的左眼和右眼视差复合图像。在一些实施例中，复合图像可以为上下交织的渲染色彩和景深的复合图像。
如图5E所示，3D视频信号的视频帧包含棋盘格式的具有2m×n分辨率的复合图像507。在一些实施例中，复合图像可以为棋盘格式的左眼和右眼视差复合图像。在一些实施例中，复合图像可以为棋盘格式的渲染色彩图像和景深图像。
本领域技术人员将明白，附图所示的实施例仅是示意性的，3D视频信号的视频帧所包含的两幅图像或复合图像可以包括其他类型的图像以及可以呈其他排布形式，这落入本发明的范围内。
在一些实施例中，m×n的分辨率可以为全高清(FHD)以上的分辨率，包括但不限于，1920×1080、1920×1200、2048×1280、2560×1440、3840×2160等。
在一些实施例中，至少一个3D处理装置130在接收到包括两幅图像的视频帧后，基于两幅图像之一渲染每个复合子像素中至少一个子像素并基于两幅图像中另一幅渲染每个复合子像素中至少另一个子像素。类似地，在一些实施例中，至少一个3D处理装置在接收到包括复合图像的视频帧后，基于复合图像渲染每个复合子像素中至少两个子像素。例如，根据复合图像中的第一图像(部分)渲染至少一个子像素，根据第二图像(部分)渲染至少另一个子像素。
在一些实施例中，这例如是基于眼部定位数据来动态渲染。
作为解释而非限制地，由于在本公开实施例中的3D处理装置130通过例如构造为内部接口的视频信号接口140接收到的视频帧数据包含的两幅图像，每个图像的分辨率(或复合图像分辨率的一半)与按照视点划分的复合像素(其包括按照视点划分的复合子像素)相对应。一方面，由于视点信息与传输过程无关，这能够实现处理计算量小且分辨率不受损失的3D显示；另一方面，由于复合像素(复合子像素)对应于视点设置，显示屏的渲染能够以“点对点”的方式实现，大大降低了计算量。相比之下，常规的3D显示器的图像或视频的传输和显示仍以2D显示面板为基础，不仅存在分辨率下降和渲染计算量剧增的问题，还可能存在多次格式调整和图像或视频显示适配的问题。
在一些实施例中，处理器101的寄存器102可用于接收有关多视点3D显示屏100的显示要求的信息，该信息典型地为与i个视点无关地且与多视点3D显示屏100的m×n分辨率相关的信息，以便处理器101向多视点3D显示屏100发送符合其显示要求的3D视频信号的视频帧。该信息例如可以为用于初始建立视频传输发送的数据包。
因此，在传输3D视频信号的视频帧时，处理器101无需考虑与多视点3D显示屏100的i个视点相关的信息(i≥3)。而是，处理器101凭借寄存器102接收到的与多视点3D显示屏100的m×n分辨率相关的信息就能够向多视点3D显示屏100发送符合其要求的3D视频信号的视频帧。
在一些实施例中，多视点3D显示终端1000还可以包括编解码器，配置为对压缩的3D视频信号解压缩和编解码并将解压缩的3D视频信号经视频信号接口140发送至至少一个3D处理装置130。
在一些实施例中，多视点3D显示终端1000的处理器101从存储器读取或从多视点3D显示终端100以外、例如通过外部接口接收3D视频信号的视频帧，然后经由视频信号接口140将读取到的或接收到的3D视频信号的视频帧传输到至少一个3D处理装置130。
在一些实施例中，多视点3D显示终端1000还包括格式调整器(未示出)，其例如集成在处理器101中，构造为编解码器或者作为GPU的一部分，用于预处理3D视频信号的视频帧，以使其包含的两幅图像具有m×n的分辨率或者使其包含的复合图像具有2m×n或m×2n的分辨率。
如前，本公开一些实施例提供的多视点3D显示终端可以是包含处理器的多视点3D显示终端。在一些实施例中，多视点3D显示终端可构造为智能蜂窝电话、平板电脑、智能电视、可穿戴设备、车载设备、笔记本电脑、超级移动个人计算机(UMPC)、上网本、个人数字助理(PDA)等。
