Canon today unveiled the REALiS 4K501ST LCoS (reflective LCD) 4K resolution projector that includes two HDMI 2.0 inputs with HDCP 2.2 support. Using a native 4K LCoS chip at 4096×2400, the projector si spec’d at 5,000 lumens and is capable of displaying 4K content at 60Hz via a single HDMI cable (4:2:0 chroma sampling, however)
What is interesting about this 4K projector is that it’s using the Digital Cinema Initiative (DCI) standard for 4K cinema (4096×2160), which is denser than the QFHD (3840×2160) resolution that nearly every other 4K projector use using.
The 4K501ST projector comes equipped with a specially designed Canon 4K short focus wide zoom lens and throw ratio of 1.0 – 1.3:1, allowing it to project a 10-foot wide image from an approximate distance of only 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 superb performance due to such sophisticated Canon optical technologies as ultra-low dispersion (UD) glass, aspherical lens elements and super spectra multi lens coatings. The lens also includes a Marginal Focus feature which helps ensure content projected on the peripheral portions of domed surfaces remains in focus.
The Canon REALiS 4K501ST projector also offers six different pre-set image modes, as well as three customizable image modes, to help optimize quality based on content type and projection environment. The projector’s DICOM Simulation Mode can be ideal for displaying monochrome digital X-rays, CAT scans and MRIs with superb grayscale gradation. This mode, which offers both clear and blue base color temperature presets, simulates the results of devices compliant with the Digital Imaging and Communications in Medicine (DICOM) Part 14 standard.
