本申请主张在2015年3月17日在中国提交的中国专利申请号No.201510116441.2的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及立体显示技术领域,特别是一种图像处理系统、方法、确定位置的方法及显示系统。
背景技术
目前的立体影像显示方式大致可分为3类,即:眼镜式、头戴显示器(Head Mount Display)式以及裸眼式。裸眼式包括许多种类,通常采用透镜阵列式技术、视差障碍式技术等实现。
裸眼立体显示系统主要由二维平面显示器(包括液晶显示器、等离子显示器、场发射显示器以及有机电致发光显示器等)配合分光器件(如光栅)组装而成。使用的光栅可分为狭缝光栅和柱面光栅等。
现有技术中,为了使得用户处于连续观看区域中,会将分光器件配置为可调式样的分光器件,进而在裸眼立体显示系统工作过程中确定观看者的当前观看距离,并对立体图像的合成参数和可控分光器件的分光参数进行联合调整,以将裸眼立体显示系统的适合观看的距离调整到该当前观看距离。
然而上述的方式中,需要配置可调节的分光器件,这大大增加了成本。同时,当视野中存在多个位于不同位置的观看距离不同的用户时,上述方式将无法工作,导致其使用受到很大的限制。

在本公开的具体实施例中,对于多视图裸眼立体显示系统而言,考虑到在左右视图颠倒的区域和连续观看区域中用户看到的图像并不相同。因此给原始视图加上标识之后,由于该标识的存在,使得用户在左右视图颠倒的区域和/或连续观看区域能够看到上述的标识,因此用户能够基于该标识的指引确定合适的观看位置。

具体实施方式
本公开实施例中,通过在视图中设置一标识,该标识被显示后可被用户看到,使得用户可以根据该标识确定合适的观看位置,以极小的成本实现了裸眼立体显示的观看指引。
本公开中的视图是指从一个特定位置单眼观看(或单相机拍摄)的关于立体场景的图像。
本公开实施例的图像处理方法如图1所示,包括:
步骤101,对当前待显示的原始图像中的多个原始视图中的至少一部分进行处理,得到目标图像,处理后的视图中包括一标识;
步骤102,对所述目标图像进行显示处理,使得用户能够基于所述目标图像中标识的组合确定能观看到3D效果的位置。
当然,在进行上述的步骤101之前,都可以获取到当前待显示的包括多 个原始视图的原始图像,然后进行步骤101的处理。
在本公开的具体实施例中,对于多视图裸眼立体显示系统而言,考虑到在左右视图颠倒的区域和连续观看区域中用户看到的图像并不相同。因此给原始视图加上标识之后,由于该标识的存在,使得用户在左右视图颠倒的区域和/或连续观看区域能够看到上述的标识,因此用户能够基于该标识的指引确定合适的观看位置。
上述的方式是基于用户观看到的图像来对用户进行指引,因此不会受到观看人数的限制。同时,上述方式仅仅需要对图像数据进行一定的修改,并不需要采用可调节的分光器件和外置的用户位置传感部件,大大降低了实现成本,因此实现了适用于多人的成本较低的用户观看位置指引。
上述的标识可以位于视图的各个位置,但综合考虑增加的标识对原有图像的影响以及标识的显著性,在本公开的具体实施例中,上述的标识设置于视图顶部的中央。
在本公开的具体实施例中,上述的标识可以以各种方式来实现,只要能够保证用户能够在左右视图颠倒的区域和连续观看区域能够看到不同的图形标识即可,下面对几种可能的实现方式结合N(N大于或等于3)视图的说明如下。
首先,对于裸眼立体显示系统而言,都具有一个连续观看区域(又可称之为合适观看的区域,在此区域中的观看位置都属于最佳观看位置),观看者有时候会因为所站的位置不合理而处于适合观看区域之外的左右视图颠倒的区域(又可称之为死区),而看不到理想的立体效果,甚至会感觉头晕。
请参照图2a,为图像形成装置进行裸眼立体显示的原理示意图。图像形成装置可以是液晶显示器、等离子显示器、场发射显示器以及有机电致发光显示器等各种能够利用多个视图的显示数据来驱动而显示图像的装置。本实施例以液晶显示面板为例,其包括多个子像素或者像素201,图2a中仅示出十个子像素或者像素201,但实际中,其可包括成千上万个子像素或者像素。图2a中的子像素或者像素201基于空间多工立体显示方式(即通过同一个画面,以像素交错的方式,同时显示左右眼的影像,然后再搭配特殊的光线控制技术来让两眼看到不同的画面)而被分成P1、P2、P3、P4、P5五类。每 五个子像素或者像素为一个群组且按周期排列以适于显示五幅视图的图像。
在此需要说明的是,像素被分成多少类,与裸眼立体图像显示所包括的视图数量相对应;举例说明:若欲显示的视图数量为四个,则像素相应地被分成四类;若欲显示的视图数量为六个,则像素相应地被分成六类,以此类推。
而分光器件202设置在显示侧以执行视图分割功能,其可以是狭缝光栅、柱面光栅,或者具有对光线进行折射分光作用的柱面透镜阵列等。
分光器件202能将液晶显示面板显示的图像进行分光而形成多个不同的视图以在各个不同方向上被投射,而对应在接收面上产生多个视域,图2a中包括五个视域:VP1、VP2、VP3、VP4及VP5。
通常情况下,对于N(N大于或等于3)视图的裸眼立体显示系统而言,依序排列的N个原始视图是从右到左的N个不同视角的图像。以3视图为例,则从右到左的3幅视图如图2b所示。
图2a所示的视域排列方式中,其中连续的VP1-VP5构成一个连续观看区域,即用户的双眼不超出这个连续观看区域时可以得到较好的观看感受,但当用户的双眼分别分布于两个相邻的连续观看区域(即用户位于左右视区发生颠倒的区域)时,则会出现左右视区颠倒的情况,在这个区域观看会导致用户头晕目眩。
从图2a的基于5视图的裸眼立体显示中可以发现,上述的左右视区发生颠倒的区域中,用户看到的视图组合为1号视图和5号视图,此时,实际上用户的左眼看到的是右眼图像,而右眼看到的是左眼图像,也就是说用户是不能正常获取3D效果的,而在适合观看的连续观看区域中,用户看到的是其他的相邻视图组合。
推广到基于N(N大于或等于3)视图的裸眼立体显示系统中,左右视区发生颠倒的区域中,用户看到的视图组合为1号视图和N号视图的组合,即第一幅视图和最后一幅视图的组合。
因此,要想使得用户能够区分自己到底是位于上述的连续观看区域,还是位于左右视区发生颠倒的区域,则需要使得用户在连续观看区域和左右视区发生颠倒的区域上看到不同的标识。
在此应该说明的是,用户在连续观看区域和左右视区发生颠倒的区域上看到不同的标识包括两种情况:
在其中一个区域看不到标识,在另一个区域能够看到标识;
在两个区域都能看到标识,但看到的标识不同。
如图3所示,在本公开的具体实施例中,以基于5视图的裸眼立体显示为例进行说明,在第一幅视图中设置第一标识(图3中为一水平线段),而在第五幅视图中设置第二标识(图3中为一垂直线段),上述的第一标识和第二标识组合后形成不同于第一标识和第二标识的第三标识(为一十字),其他视图不更改。
在这种情况下,当用户处于左右视区发生颠倒的区域时,能够同时看到第一幅视图和第五幅视图,因此用户实际看到的是水平线段和垂直线段的组合体,即用户看到的是一个十字标识。
而当用户处于连续观看区域时,有三种情况:
1、用户能够看到第一幅视图,但看不到第五幅视图,此时用户看到的标识为水平线段;
2、用户能够看到第五幅视图,但看不到第一幅视图,此时用户看到的标识为垂直线段;
3、用户既不能看到第一幅视图,也不能看到第五幅视图,此时用户看不到任何标识。
可以发现,上述3种情况下,用户看到的标识和用户处于左右视区发生颠倒的区域时看到的十字标识均不相同。
也就是说,上述情况下,只要用户看到了十字标识,用户就能够基于看到的十字标识判断出自己处于左右视区发生颠倒的区域,此时用户就会左右移动,直至视野中出现水平线段或垂直线段或没有任何标识。
当然,应当理解的是,上述设置于第一幅视图和第五幅视图的标识还可以是其他任何类型的标识,只要二者能够组合成其他标识即可,如设置于第一幅视图和第五幅视图的标识分别为位于不同位置的圆,又如设置于第一幅视图和第五幅视图的标识分别为位于同一位置,但指示方向不同的箭头标识等,在此不一一举例说明。
推广到基于N(N大于或等于3)视图的裸眼立体显示时,本公开实施例中,在依序排列的N幅视图中,在第一幅视图和最后一幅视图分别设置第一标识和第二标识,其他视图不设置标识,上述的第一标识和第二标识组合后形成不同于第一标识和第二标识的第三标识。
在本公开的具体实施例中,还可以是在依序排列的N幅视图中,除第一幅视图和最后一幅视图外均设置标识,这种方式下,也可以使得用户能够在连续观看区域和左右视区发生颠倒的区域上看到不同的标识,说明如下。
如图4所示,在第二、三和四幅视图中设置圆圈标识,其他视图不更改。
在这种情况下,当用户处于左右视区发生颠倒的区域时,能够同时看到第一幅视图和第五幅视图,由于第一幅视图和第五幅视图上没有任何标识,所以用户实际看不到任何标识。
而当用户处于连续观看区域时,有三种情况:
1、用户能够看到第一幅视图,但看不到第五幅视图,虽然第一幅视图上没有标识,但此时用户看到的其他视图上有圆圈标识,因此用户最终能够看到圆圈标识;
2、用户能够看到第五幅视图,但看不到第一幅视图,虽然第五幅视图上没有标识,但此时用户看到的其他视图上有圆圈标识,因此用户最终能够看到圆圈标识;
3、用户既不能看到第一幅视图,也不能看到第五幅视图,但此时用户看到的其他视图上都有圆圈标识,因此用户最终能够看到圆圈标识。
可以发现,上述3种情况下,用户都能够看到圆圈标识,和用户处于左右视区发生颠倒的区域时无法看到任何标识的情况均不相同。
也就是说,上述情况下,只要用户无法看到任何标识,用户就能够判断出自己处于左右视区发生颠倒的区域,此时用户就会左右移动,直至视野中出现圆圈标识。
在上述的方式中,将多个依序排列的原始视图分为两组,第一组包括首视图和尾视图,第二组包括其他视图,也就是说,一种方式是在第一组视图设置标识,而另一种方式是在第二组视图设置标识,二者均可以单独使用。
可以发现,从节约处理资源,提高视图处理速度的角度来看,当N大于 或等于5时,上述的方式一需要处理的图像较少,因此此时选择方式一进行处理;当N小于5时,方式二处理的图像较少,此时选择方式二进行处理。
也就是说,所述原始图像包括多个依序排列的原始视图时,所述对所述多个原始视图中的至少一部分进行修改具体包括:
确定所述多个依序排列的原始视图的视图数量;
在所述视图数量大于或等于5时,在第一幅视图和最后一幅视图分别设置第一标识和第二标识,其他视图不设置标识,在所述视图数量小于5时,在第一幅视图和最后一幅视图之外的其他视图设置第四标识;
上述的第一标识和第二标识组合后能够形成不同于第一标识和第二标识的第三标识。
通过上述方式,使得本公开实施例能够对基于不同数量的视图的立体显示图像数据进行区别对待,以尽可能小的代价实现观看指引。
而上述的两种方式中,都存在用户看不到标识的情形,这种情况下不利于有效的指示用户。因此,为了能够更有效的指示用户,在本公开的具体实施例中,所述原始图像包括多个依序排列的原始视图时,所述对所述多个原始视图中的至少一部分进行修改具体包括:
第一幅视图和最后一幅视图分别设置第一标识和第二标识;
在第一幅视图和最后一幅视图之外的其他视图设置第四标识;
所述第一标识和第二标识组合后能够形成不同于第一标识和第二标识的第三标识;
设置有第一标识或第二标识的视图和设置有第四标识的视图分别作为左眼图像和右眼图像被用户看到时,所述第一标识或第二标识被所述第四标识遮挡。
如图5所示,在第二、三和四幅视图中设置实心圆圈标识,而在第一幅视图中设置朝向左方的空心箭头,而在第五幅视图中设置朝向右方的空心箭头。
为了保证用户在连续观看区域看到的准确的标识,当所有的视图放到同一个坐标系中对比时,需要保证图5中所示意的朝向左方的空心箭头和朝向右方的空心箭头在视图中所占据的区域位于实心圆圈标识在视图中所占据的 区域内,三个标识的轮廓之间的尺寸及相互位置关系如图6a-6d所示。请注意,图6a-6d仅仅表示三个标识的轮廓之间的尺寸及相互位置关系,并不表示用户实际看到的图像。
实际使用过程中,对应于6a所示的三个标识的轮廓之间的尺寸及相互位置关系,则用户实际看到的朝向右方的空心箭头标识和实心圆圈标识的组合如图6e所示,朝向左方的空心箭头标识和实心圆圈标识的组合如图6i所示;对应于6b所示的三个标识的轮廓之间的尺寸及相互位置关系,则用户实际看到的朝向右方的空心箭头标识和实心圆圈标识的组合如图6f所示,朝向左方的空心箭头标识和实心圆圈标识的组合如图6j所示;对应于6c所示的三个标识的轮廓之间的尺寸及相互位置关系,则用户实际看到的朝向右方的空心箭头标识和实心圆圈标识的组合如图6g所示,朝向左方的空心箭头标识和实心圆圈标识的组合如图6k所示,对应于6d所示的三个标识的轮廓之间的尺寸及相互位置关系,则用户实际看到的朝向右方的空心箭头标识和实心圆圈标识的组合如图6h所示,朝向左方的空心箭头标识和实心圆圈标识的组合如图6l所示。
然后通过颜色、透明度等方面的配合,即可保证设置有第一标识或第二标识的视图和设置有第四标识的视图分别作为左眼图像和右眼图像被用户看到时,所述第一标识或第二标识被所述第四标识遮挡,说明如下。
当用户同时看到朝向左方的空心箭头/朝向右方的空心箭头和实心圆圈标识,由于二者之间的上述位置关系,用户看到的就是实心圆圈标识。
此时,当用户处于左右视区发生颠倒的区域时,能够同时看到第一幅视图和第五幅视图,因此用户看到的图形如图7所示为朝向右方的空心箭头标识和朝向左方的空心箭头标识组合后的标识,而当用户处于连续观看区域时,有三种情况:
1、用户能够看到第一幅视图,但看不到第五幅视图,虽然第一幅视图上有朝向左方的空心箭头,但此时用户看到的其他视图上有实心圆圈标识,由于二者之间的相互位置关系,用户最终能够看到实心圆圈标识;
2、用户能够看到第五幅视图,但看不到第一幅视图,虽然第五幅视图上有朝向右方的空心箭头,但此时用户看到的其他视图上有实心圆圈标识,由 于二者之间的相互位置关系,用户最终能够看到实心圆圈标识;
3、用户既不能看到第一幅视图,也不能看到第五幅视图,但此时用户看到的其他视图上都有实心圆圈标识,因此用户最终能够看到实心圆圈标识。
可以发现,上述3种情况下,用户都能够看到实心圆圈标识,和用户处于左右视区发生颠倒的区域时看到的如图7所示的朝向右方的空心箭头标识和朝向左方的空心箭头标识组合后的标识均不相同。
也就是说,上述情况下,只要用户看到朝向右方的空心箭头标识和朝向左方的空心箭头标识组合后的标识,用户就能够判断出自己处于左右视区发生颠倒的区域,此时用户就会左右移动,直至视野中出现实心圆圈标识,而用户看到心圆圈标识就表明用户处于连续观看区域,无需移动。
可以发现,上述的方式中,用户处于任意一个区域都能够看到有效的标识,进而能够根据看到的标识确定自己所处的观看位置是否合适。
从以上描述可以发现,为了给用户进行观看位置的指示,本公开实施例需要对待显示的图像帧中的视图进行标识增加处理。而在视图中增加标识是一种图像处理操作,而图像处理操作都需要耗费大量的处理器资源。但绝大部分情况下,用户都不会在一种持续运动的状态下观看立体影像,因此当用户已经在本公开实施例的方法的指示下处于合适观看的区域中,此时继续进行指示处理不但影响用户的观看体验,还会消耗掉极为宝贵的处理资源。
考虑到上述的情况,在本公开的具体实施例中,还包括:
在基于所述目标图像进行显示处理后由定时模块设定一处理模块工作时间;
定时模块到时后,停止所述对所述多个原始视图中的至少一部分进行修改的处理,直接基于所述原始图像进行显示处理。
此时,利用本公开实施例的方法能够指示用户运动到连续观看位置,在指引完成后即可关闭上述的指示处理,以降低对用户观看的影响,同时节省处理器资源。
然而,虽然用户在观看过程中不会持续移动,但用户可能在观看过程中有可能会发生突发性的移动(如调整坐姿等),或者有新的用户加入,此时应该重新启动指示处理,以引导偏离连续观看区域的原有用户或新加入的用户 进入连续观看区域。
考虑到上述的情况,在本公开的具体实施例中,还包括:
判断是否需要重新启动指示处理,在判断需要重新启动时,输出重新启动指示;
接收到重新启动指示时,启动所述对所述多个原始视图中的至少一部分进行修改的步骤,以基于所述目标图像进行显示处理。
在本公开具体实施例中,在如下的情况下需要重新启动指示处理:
1、当前用户发生移动;
