摘要
The stereo vision results from the interaction between geometrical optics and visual psychology.Large depth will bring discomforts for the results of ghosting and flicker.The relevance of the ratio of jumping out depth(RJD)and electroencephalogram(EEG)gravity frequency(GF)was explored to re flect human health under di®erent three-dimensional(3D)depth information(mainly the negative disparity)displayed on a three-dimensional television(3D-TV)with shutter glasses.EEG was obtained from 10 volunteers when they were watching 3D film segments with di®erent negative disparities.The brain GF map shows that the depth information has a stronger in fluence on the frontal lobe than on the occipital lobe.For regression analysis,nonlinear curve fittings of GF to RJD in Fp1,F3,O2 and T5 channels were mainly performed when RJD ranged from 0 to 3.4,while linearfittings were performed in some special RJD ranges.It also confirms that RJD above 2.2 may lead to discomfort to human body.Finally,it suggests a suitable RJD range for people to watch from the objective method.The outcomes can be used as a guidance to decrease human discomforts induced by 3D production.
