동일 시차에 대한 3D 디스플레이 장치별 입체감 차이 분석

Abstract

In this study, the differences in the perceived depth depending on the type of 3D display device were empiricallyinvestigated using the stereoscopic 3D images including a primary object or person in the center of the image. First, theexperiment images were generated by dividing the depth of the primary object or person into 4 steps. Next, the experimentimages were displayed through the 4.3-inch mobile 3D display, then the participants were instructed to adjust the parallaxfor the primary object to get the same depth perception for the same experiment image through the 27-inch or 55-inch 3Ddisplay device. As a result, there were significant differences in the depth perception through three different devices in thesame parallax condition. Finally, we represented the difference of the depth perception among the different devices by theparallax function derived from regression analysis. These characteristics of device-specific depth perception with respect toparallax are important in the 2D-to-3D conversion process, and these understandings can be used as guidelines.
