Canon U.S.A. Inc. recently unveiled its REALiS 4K500ST Pro AV LCOS Projector
which delivers 4K resolution of 4096 x 2400, up to 5000 lumens and Canon’s LCOS
Technology with AISYS-enhancement for high-brightness and detailed image
reproduction. The REALiS 4K500ST also offers a Genuine Canon 4K lens and a
collection of advanced professional setting features, including Marginal Focus which
helps ensure content projected on the peripheral portions of domed surfaces
remains in focus.
This model also offers compact and lightweight form factors of a high brightness 4K
projector. The REALiS 4K500ST’s combination of image quality, advanced features
and compact size make it ideal for applications like immersive simulation and
training which require image quality but may have limited spacing.
Optics
The 4K500ST projector comes equipped with a specially designed Genuine Canon 4K
short focus wide zoom lens and throw ratio of 1.0 – 1.3:1, allowing it to project a
ten foot wide image from an approximate distance of 10 feet. This projection lens
possesses advanced spherical focus capabilities derived from Canon’s L-Series EF
camera lenses which is distinguished by a bold red ring around the outer barrel. The
lens delivers, due to Canon optical technologies, as ultra-low dispersion (UD) glass,
aspherical lens elements and super spectra multi lens coatings.
Advanced Canon optical technology in the REALiS 4K500ST is also present in its
AISYS (Aspectual Illumination System) Optical Engine. This unique engine helps
ensure the projector delivers an ideal combination of both brightness (up to 5000
lumens) and contrast ratio (up to 2500:1), while also helping the projector maintain
a small form factor. The 4K500ST is also able to deliver a virtually consistent level
of brightness throughout its zoom range thanks to the combination of the Genuine
Canon 4K lens and AISYS Optical Engine.
LCOS Technology with AISYS-enhancement
The 4K500ST is the newest member of the REALiS Projector series which all feature
Canon’s LCOS (Liquid Crystal on Silicon) Technology with AISYS-enhancement. This
technology is renowned for delivering virtually seamless images with colour
reproduction, and low-latency playback for improved display of video content. In
addition to offering resolution of 4096 x 2400, the REALiS 4K500ST is capable of
projecting other 4K resolutions such as the DCI (Digital Cinema Initiative) standard
of 4096 x 2160 as well as Quad Full High Definition (QFHD) of 3840 x 2160.
Image Processing
The REALiS 4K500ST also integrates dual image processing engines that execute
tasks such as smooth reproduction of uncompressed 4K video at 60 or 30 fps, and
two upscaling technology options (BiCubic and Canon’s unique Shape Trace) to
optimise 2K video and other non-native 4K resolution content.

Canon REALiS 4K500ST is scheduled to be available through authorised Canon dealers by April 2016.
