Abstract: A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the plane of the display increases. Data layers are sampled using a plenoptic sampling scheme and rendered using hybrid rendering, such as perspective and oblique rendering, to encode light fields corresponding to each data layer. The resulting compressed, (layered) core representation of the multi-dimensional scene data is produced at predictable rates, reconstructed and merged at the light field display in real-time by applying view synthesis protocols, including edge adaptive interpolation, to reconstruct pixel arrays in stages (e.g. columns then rows) from reference elemental images.

Abstract: The present technology relates to an imaging apparatus capable of offering useful information with higher certainty. An imaging apparatus includes an optical system that condenses light received from a subject, an imaging device that photoelectrically converts the light received from the optical system to form a pickup image, and a cover glass disposed between the optical system and the imaging device to protect a surface of the imaging device. The cover glass is disposed obliquely to the imaging device. When stray light corresponding to light reflected on the imaging device enters the cover glass as a part of light having entered the imaging device via the optical system and the cover glass, this stray light is reflected on the cover glass toward a low harmful area of the imaging device. Accordingly, flares generated by stray light decreases in a recognition useful area. The present technology is applicable to an on-vehicle camera, a ceiling type monitoring camera, or others.
