In three-dimensional television (3D TV) broadcasting, we find the effect of fundamental depth resolution and the cardboard effect to the perceived depth resolution on multi-view display is important. The observer distance and the specification of multi-view display quantize the expressible depth range, which affect the perception of depth resolution of the observer. In addition, the multi-view 3D TV needs the view synthesis process using depth image-based rendering which induces the cardboard effect from the relation among the stereo pickup, the multi-view synthesis and the multi-view display. In this paper, we analyze the fundamental depth resolution and the cardboard effect from the synthesis process in the multi-view 3D TV broadcasting. After the analysis, the numerical comparison and subjective tests with 20 participants are performed to find the effect of fundamental depth resolution and the cardboard effect to the perceived depth resolution.
在三维电视（3D TV）广播中，我们发现基本深度分辨率的影响以及多视图显示中对感知深度分辨率的纸板效应很重要。观察者距离和多视图显示的规格对可表达深度范围进行量化，这会影响观察者对深度分辨率的感知。此外，多视图3D电视需要使用基于深度图像渲染的视图合成过程，该过程会从立体拾取、多视图合成和多视图显示之间的关系中引发纸板效应。在本文中，我们从多视图3D电视广播中的合成过程分析基本深度分辨率和纸板效应。分析之后，对20名参与者进行了数值比较和主观测试，以找出基本深度分辨率和纸板效应对感知深度分辨率的影响。
