CONFERENCE PROCEEDINGS FREE ACCESSWe have studied which shape of screen is most advantageous when wide-field-of-view images are displayed. Evaluation was carried out through the 'Virtual Screen' method in which various curvatures are virtually formed using a binocular three-dimensional display system. The concave screen with a moderate curvature was preferable to the convex or extremely concave shapes.View full abstractDownload PDF (518K) -

CONFERENCE PROCEEDINGS FREE ACCESSResearch on shooting methods of 3D program production for natural 3D images has been continued. In this paper, we subjectively verified the reproduced 3D images shot by the orthostereoscopic conditions which was proved to copy the real space into 3D space geometrically. Using a mannequin standing in the hallway, subjective evaluation tests showed that the ratio of subjective distance to subjective size for the 3D mannequin shot by the orthostereoscopic conditions was much the same as that for the real mannequin. But the variation of screen size made the differences of absolute size of the mannequin.View full abstractDownload PDF (717K) -

CONFERENCE PROCEEDINGS FREE ACCESSCalcarine cortex has retinotopic organization. This retinotopic organization can be observed by PET under point to point stimulation strategy. Activity in calcarine cortex has stimuli frequency dependence, and increased blood flow is dependent on stimulation flicker frequency. PET also indicate the direction of active pathway in the brain under certain visual stimulation. These include occipito-parietal (dorsal) pathway and occipito-temporal (ventral) pathway, corresponding to spatial recognition and pattern and color recognition, respectively.View full abstractDownload PDF (643K) -

CONFERENCE PROCEEDINGS FREE ACCESSBinocularly unpaired regions on an Object, in which left eye image and right eye image could not be corresponded each other, play an important role in human stereo perception. We found experimentally that the volume perception is strongly depending on the existence of the binocularly unpaired regions. In this paper, we would like to introduce some experimental results showing that the volume perception to further back of an object with binocularly unpaired regions.View full abstractDownload PDF (514K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, a new method for objective picture quality assessment taking account of noise sensitivity which depends on objects is proposed. Firstly, objects are extracted from background for every input frame. In addition to conventional noise weighting manner such as WSNR and dispersion of gaze points, mosquito noise, blocking artifacts and speed of gaze point are considerd for object regions utilizing object-oriented noise weighting. Details and the performance of this method are described herein.View full abstractDownload PDF (679K) -

CONFERENCE PROCEEDINGS FREE ACCESSCross talk between left and right images on a 3D display deteriorates the picture quality severely. This paper describes qualitatively how the cross talk occurs and shows some experimental results. In a projection type display, a rear screen and a mirror affect the polarization. Strain on manufacturing process causes double refraction in screen. Due to the double refraction, when the incident light is linear polarized one the output is elliptically polarized light and cross talk occurs. A mirror has a complex refractive index and when linear polarized light is reflected, the output is elliptically polarized light, producing cross talk.View full abstractDownload PDF (878K) -
