In these days, Integral Photography has been extensively studies. As a major problem of IP, there is a problem that the depth of the displayed 3D image is reversed from the original object. As a method to solve this problem, there is a method using a concave lens array for recording and using a convex lens array for display. However, in this method, there is a large difference between the incident angle of light ray incident on the lens at the time of recording and the display angle of the light ray emitted from the lens at the time of display. So, in this research, we proposed a photographing method of IP with high angle reproducibility of light rays by using convex mirror array for recording. From the analysis on the optical path of the light ray incident on each convex mirror, it was revealed that the proposed method has higher angle reproducibility of light rays than the conventional method. In the experiment comparing 3D images displayed by the proposed method and the conventional method, it was confirmed that the image displayed by the proposed method has larger parallax according to the movement of the observer than that of the conventional method.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
