立体电视节目的误差容限研究

Limits of 3DTV Distortions

本文通过主观评价试验,研究了立体电视节目的垂直误差、旋转误差、尺寸误差、整体亮度误差、白切割电平误差、黑切割电平误差、色调误差7种误差的容限范围。根据试验结果,确定了立体电视节目在拍摄制作过程中的误差容限,垂直误差不应超过5像素,旋转误差不应超过0.4°,尺寸误差不应超过0.8%,整体亮度误差不应超过8%,白切割电平误差不应超过6%,黑切割电平误差不应超过10%,色调误差不应超过16°。

In this paper, limits of 3DTV distortions of stereoscopic images are studied based on subjective evaluation. We explore the limits of 3DTV distortions, including geometrical distortions, brightness distortions and color distortions. The experiment result shows that vertical shift should not exceed 5 pixels, rotation error should not exceed 0.4°, size inconsistency should not exceed 0.8%, overall luminance difference should not exceed 8%, white clip level inconsistency should not exceed 6%, black Clip level inconsistency should not exceed 10%, and color distortions should not exceed 16°.
