A chroma key and presentation system, a presentation method, and a presentation kit all for simultaneous use in the presence of an in-person audience and remote audience. The system comprising: a chroma key light source, configured in use to emit chroma key light; a display surface which may be used as a projector screen for displaying projected media for viewing by the in-person audience from a projector, the display surface being at least partially transparent to the chroma key light; a camera disposed on an opposing side of the display surface to the chroma key light source, wherein the camera is configured to receive chroma key light for use in generating a composite image for the remote audience; and a directional light control filter, configured to reduce chroma key light transmission in a direction away from the camera.

The present seam visually suppresses a gap defined between two adjacent reflective surfaces. The seam comprises a strip of light propagating material and a plurality of lighting units. The strip of light propagating material defines a front surface, two side surfaces and a back surface. The side surfaces of the strip of light propagating material is adapted for being positioning in the gap defined between the adjacent reflective surfaces. The lighting units are positioned along the back surface of the strip of light propagating material and are adapted for propagating light in the strip of light propagating material. When light is propagated in the strip of light propagating material, the gap between the two adjacent reflective surfaces is visually suppressed.

An image display device according to an aspect of the present technology includes an emission portion, a transparent base material, an irradiation target, and an optical portion. The emission portion emits image light along a predetermined axis. The transparent base material includes a tapered surface having a tapered shape along the predetermined axis. The irradiation target is disposed at at least a part around the predetermined axis along the tapered surface. The optical portion controls an incident angle of the image light on the irradiation target, the image light having been emitted from the emission portion, the optical portion being disposed in a manner that the optical portion faces the emission portion on the basis of the predetermined axis.

A display apparatus (1) of the present invention includes: a transparent screen (10) configured by a transmissive or reflective volume hologram; a first image projection section (50a) disposed on a first main surface (Sa) side of the transparent screen (10), and projecting first image light (La1) onto the first main surface (Sa); and a second image projection section (50b) disposed on a second main surface (Sb) side of the transparent screen (10), and projecting second image light (Lb1) onto the second main surface (Sb). The display apparatus (1) further includes: a first light-shielding section (40a) preventing external light from being directly incident on the first main surface (Sa) at least at same incident angle as the first image light (La1); and a second light-shielding section (30b) preventing external light from being directly incident on the second main surface (Sb) at least at same angle as the second image light (Lb1).

The invention is a small, low-power consuming, projector system. Once programmed and provided with image data, it can be a standalone system for presenting varying length, silent, videos. Its programmability and FPGA-based micro-circuitry allows it to be repurposed with minimal effort to support other embedded-light-system applications.
