We have been proposing lens-less light-field imaging with Fresnel zone aperture (FZA) in front of an image sensor in a few millimeter spacing. Synthesized shadows of real FZA with the incident light generate moiré fringes interfering with another virtual FZA in a computer and result in reconstructed images by simple Fast Fourier Transform (FFT). In order to obtain clear images in this configuration, it is necessary to cancel several kinds of noise component in the detected image signals. We describe details of the process and discuss its effectiveness theoretically and experimentally in this paper.
I have been doing some development of video programs and video systems that promote scientific
communication utilizing high presence sensation created by visual experiences such as dome and
VR at science museums and companies.
In this lecture, I will report the design strategy and guidelines on the science communication on
the high-definition digital projector replaced by film since Aichi Expo and the project using HMD
recently based on case examples.
This talk introduces two topics. First one is introduction of the Sports Brain Science Project. This aims at understanding and improving brain function of athletes by using both neuro science and information-communication technology. Second one is introduction of sports training system using virtual reality technology. It focuses on providing a virtual experience as if a user is standing on the playing field on an actual game. The primary concept of the system is to make the user get accustomed through virtual experience, and thus, to improve the user's performance. Cooperation of these two projects yields synergistic effects on understanding athlete's brain function and on considering strategy for providing experience. To the extent of this article, we focus on VR-based representation mainly employing baseball.
