3D Communication System using Slit Light Field
Booth no: et_0006

Summary: By integrating a newly-developed light field camera and a slit-based light field display, we developed a 3D communication system, which can reduce information required to reproduce light rays of a remote space. Light field camera is some arranged CMOS cameras paired with each light array on a slit-based light field 3D display. An image captured by a camera is sampled and divided into lines in the vertical direction. The divided line of the image is presented by the corresponding light array. The line to be displayed is changed according to the direction of the rotating slit of the light array so that all the divided lines are reproduced correctly. This procedure reproduces light rays, which entered a camera, as if they come out from the actual objects. The cameras are installed and arranged in a row at the same interval the light arrays do. By using the slit-based light field 3D display and the light field camera with arranged CMOS cameras, it is possible to reproduce light rays at a distant space.
