CONFERENCE PROCEEDINGS FREE ACCESSThere is a problem in the integral three-dimensional (3D) display using the direct-view type display panel that color moiré occurs in the 3D image by the sub pixel structure for color display of the panel. We have proposed a method of reducing color moiré by combining reconstructed 3D images with multiple direct-view type display devices and reported the results of two-unit synthesis. In this paper, we show that color moiré can be suppressed more effectively by combining three display devices. In addition, the effect of improving the resolution characteristics of the 3D image in three-unit synthesis was also verified.View full abstractDownload PDF (747K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have been developing the most suitable video coding for an integral 3D image to implement a 3D television service. To reduce the amount of information needed to reconstruct an integral image, we evaluate the correlation between the quality of the integral imaging and the number of multi views. In this study, we show the results for the correlation and the compression performances when fewer multi views including the depth views are coded by 3D-HEVC. We compared compression performance when coding all views and coding fewer views including depth views. The results showed that coding fewer multi views including depth views enhanced the efficiency of the compression performance more than coding all views.View full abstractDownload PDF (674K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn order to enrich the sports TV programs, there are various requests to obtain the useful information during the game for on-air graphics. Especially, for any ball game, time series 3D positional data of the ball is the one of the most important information. We developed a new on-air 3D graphics system for live sports broadcasting, it is equipped with object tracking function, to track a volleyball. The positional data of the ball is calculated in real-time, both from video analysis of PTZ cameras for broadcasting, and from PTZ sensor data. Our experiment shows that the system can produce accurate 3D ball compositing in real-time for on-air graphics.View full abstractDownload PDF (705K) -
