“…After the commercialization of 3D using the special eyeglass, research on autostereoscopic 3D is under way to remove the discomfort of wearing special eyeglass. [2][3][4][5][6][7][8][9][10] In viewing autostereoscopic 3D using lenticular lens or parallax barrier, viewing positions critically affect the image quality of the observed 3D images. People who research and develop autostereoscopic 3D are skilled in evaluating the observed 3D image and finding good viewing positions.…”

Viewing positions of autostereoscopic 3D affect the observed 3D image quality. The response of the people who had little experience in viewing autostereoscopic 3D was investigated. Thirty participants with the normal stereoscopic vision were selected and took the visual evaluation of autostereoscopic 3D at the various viewing positions. Photograph was also taken for the quantitative analysis of the viewing zone characteristics and the uniformity of 3D screen of autostereoscopic 3D. In visual evaluation, the larger difference of good and bad 3D image quality was observed at the viewing distance of 300 cm than at other viewing distance. This result and the periodic trends accorded with the analysis of photos at various camera positions. From these, we found that even the unexperienced viewer can correctly evaluate whether 3D image quality is good or bad.

“…Auto-stereoscopic multi-view 3D is a 3D technology with which the user can perceive the stereoscopic image without special eyeglasses as reported in multiple studies. [1][2][3][4][5][6][7][8] Some studies reported various evaluation and measurement methods for 3D. [9][10][11][12][13][14] With the availability of ultra high-definition (UHD) and increasingly advanced display panels that are characterized by high resolutions with a large number of pixels, the number of views for a multi-view 3D image can be increased to obtain a better 3D performance.…”

Effect of 3D depth on the resolution and the observed image for auto‐stereoscopic multi‐view 3D display

In auto‐stereoscopic multi‐views, blurring occurs due to the incomplete separation of views for non‐zero depths. How this blur affects a 3D image was investigated using the commercial multi‐view 3D. The 3D input signal consisted of the square pattern and the gratings of various width and gray level values of G1 and G2. The various combinations of G1 and G2 were used to investigate the dependence of blur on gray G1 and G2 values. The 3D depth caused blurring, which caused a decrease in contrast modulation. Hence, the 3D resolution determined from contrast modulation was affected by the depth and became worse with increasing depth. Therefore, 3D resolution may be used to define the depth range within which the image degradation due to blurring is acceptable. Blur edge width values at the boundaries of gray G1 and G2 were measured and found to be similar irrespective of G1 and G2 values at the same depth. This was because blur was caused by the incomplete separation of views that are independent of G1 and G2. Hence, the blurriness of the observed 3D image is determined only by the depth. The 3D resolution and blur edge width might be useful to characterize the performance of auto‐stereoscopic multi‐view 3D.

Subpixel area-based evaluation for crosstalk suppression in quasi-three-dimensional displays

et al. 2017

A subpixel area-based evaluation method for an improved slanted lenticular film that minimizes the crosstalk in a quasi-three-dimensional (Q3D) display is proposed in this paper. To identify an optimal slant angle of the film, a subpixel area-based measurement is derived to evaluate the crosstalk among viewing regions of the intended subpixel and adjacent unintended subpixel by taking the real subpixel shape and black matrix into consideration. The subpixel mapping, which corresponds to the optimal slant angle of the film, can then be determined. Meanwhile, the viewing zone characteristics are analyzed to balance the light intensity in both right and left eye channels. A compact and portable Q3D system has been built and appropriate experiments have been applied. The results indicate that significant improvements in both crosstalk and resolution can be obtained with the proposed technique.
