Stereoscopic 3D (S3D) displays use spatial or temporal interlacing to send different images to the two eyes. Temporal interlacing delivers images to the left and right eyes alternately in time; it has high effective spatial resolution but is prone to temporal artifacts. Spatial interlacing delivers even pixel rows to one eye and odd rows to the other eye simultaneously; it is subject to spatial limitations such as reduced spatial resolution. We propose a spatiotemporal-interlacing protocol that interlaces the left- and right-eye views spatially, but with the rows being delivered to each eye alternating with each frame. We performed psychophysical experiments and found that flicker, motion artifacts, and depth distortion are substantially reduced relative to the temporal-interlacing protocol, and spatial resolution is better than in the spatial-interlacing protocol. Thus, the spatiotemporal-interlacing protocol retains the benefits of spatial and temporal interlacing while minimizing or even eliminating the drawbacks.
立体3D(S3D)显示器利用空间或时间交错技术将不同图像发送到两只眼睛。时间交错技术在时间上交替地将图像传送到左眼和右眼;它具有较高的有效空间分辨率,但容易出现时间伪像。空间交错技术同时将偶数像素行传送到一只眼睛,奇数行传送到另一只眼睛;它受到空间限制,如空间分辨率降低。我们提出了一种时空交错协议,该协议在空间上交错左眼和右眼视图,但每行图像在每一帧交替传送到每只眼睛。我们进行了心理物理学实验,发现相对于时间交错协议,闪烁、运动伪像和深度失真显著减少,并且空间分辨率优于空间交错协议。因此,时空交错协议保留了空间和时间交错的优点,同时将缺点最小化甚至消除。
