The authors argue that two factors may be involved in the subjective effect of visual noise interferences, namely the degree of correlation between the noise patterns of the left- and right-eye picture and the in-depth separation between a stereoscopically localized noise and the displayed objects. An exploratory study was conducted to test if a standard subjective assessment procedure would reveal any substantial effects of both factors. Results were that subjective impairment decreased significantly when correlation decreased, while the effect of in-depth separation was only marginal. Regarding TV applications, it is concluded that under specified conditions the signal-to-noise ratio of 3D TV may be about 3 dB smaller than that of an iso-quality 2D TV.enrandom noisestandardstelevision interferencevideo signalsvisual perceptionstereoscopic picturetv interferencedynamic visual noise interference3d tv picturesnoise patternsin-depth separationstandard subjective assessmentsignal-to-noise ratio621journal article
