The REALiS 4K501ST Pro AV 5000-Lumen LCoS Projector from Canon combines 4K resolution, high brightness, and a collection of features in a compact size. The projector's native 4K resolution (4096 x 2400) produces an image made up of more than 9.8 million pixels. This resolution exceeds both the DCI 4K cinema standard (4096 x 2160) and 4K TV's QFHD (3840 x 2160). At more than four times the detail of Full HD (1920 x 1080), the 4K501ST's resolution delivers sharp images with good color reproduction, creating a highly detailed visual experience.
The REALiS 4K501ST comes equipped with a Canon 4K short focus wide zoom lens with a consistent f/2.6 aperture and throw ratio of 1.0 to 1.3:1. It also uses Canon's high-speed dual image processing engines to reproduce uncompressed 4K video at up to 60 fps, and BiCubic and Canon's proprietary Sharp Trace that work together to maximize the quality of 2K video and other non-native 4K resolution content.
Up to 5000-Lumen Brightness and 3000:1 Contrast Ratio
When used in Presentation mode with the lamp set to Full Power mode, the REALiS 4K501ST projects bright 5000-lumen images with up to a 3000:1 contrast ratio. The high contrast ratio helps ensure deep blacks and bright whites. The results are images with crisp depth and dimension, and good color accuracy.
Compact, Lightweight Design with 1.0 to 1.3:1 Short Throw Ratio
The AISYS Optical Engine independently controls light in both vertical and horizontal directions to achieve a high level of brightness and contrast. Combined with a small LCoS panel size of 0.76", the projector is compact with a height of 6.9 ", width of 18.5", and weight of 39.6 lb.
Minimal Image Distortion and Consistent Brightness Throughout Zoom Range
The 4K short-focus wide zoom lens projects virtually distortion-free 4096 x 2400 resolution images. The design includes the same bold red ring around the lens barrel as Canon's L-series EF camera lenses. The lens itself features a multitude of Canon technologies, such as dual-sided aspherical lens elements as well as Ultra-Low Dispersion (UD) lens elements. These elements reduce chromatic aberration, curvilinear distortion, ghosting, and flare to create sharp and clear images in a compact size.
Marginal Focus and Dual Image Processing Engines
An aperture of f/2.6, as well as the Marginal Focus feature, allow images to be rendered accurately onto a variety of curved surfaces. Where other projectors may distort or bow at the edges, Canon's optical technology keeps the image straight with low TV distortion. Brightness remains virtually consistent at 5000 lumens throughout the 1.3x zoom range. Dual Image Engines execute complex image processing for uncompressed 4K 60p playback and upscaling of non-4K content. Canon's dual image processing engines let the projector produce accurate color reproduction of virtually all content. The engines also allow the projector to offer a variety of features that help enhance the quality of still and motion images.
4K Playback and Upscaling
The projector smoothly reproduces uncompressed 4K video at up to 60 frames per second, for a natural fluid feel and detailed content. Non-4K content will be maximized utilizing two upscaling technologies of BiCubic and Canon's proprietary Sharp Trace, which detects contours of an image in a diagonal direction and performs interpolation, resulting in a stunningly smooth image.
Image Quality Adjustments
The REALiS 4K501ST offers extensive image quality adjustments to suit a wide range of user preferences. These include six different preset Image Modes (and three additional customizable Image Modes), and many adjustments that allow users to customize image and color characteristics to fulfill their specific imaging needs. The Standard mode is suitable for bright rooms, and when using computer screens or motion picture content. The Presentation mode is suitable for somewhat bright rooms when text needs to be clear. For rooms that are somewhat bright, and when you want to show motion picture content, you can operate the projector in Dynamic mode. The Photo/sRGB mode lets you project images from sRGB-supported digital cameras. For using the projector in rooms that are somewhat dark or when projecting video content, you can run the projector in Video mode.
The DICOM Simulation mode is suitable for displaying medical images in non-diagnostic settings. Both Blue Base and Clear Base settings are supported. Note: The projector has not been cleared or approved for medical diagnosis and should not be used for these purposes.
Motion Blur Reduction
The REALiS 4K501ST includes Canon's Motion Blur Reduction feature for improved visibility when movement is fast. By inserting extra frames to video content, motion blur is reduced and the clarity of graphics and text on fast-moving objects is preserved. Three different modes (Strong, Low, and Off) are included for flexibility, with each depending on the level of movement and type of video content. When used in this mode, the projector's brightness is affected.
Motorized vertical (±60%) and horizontal (±10%) lens shift allows for adjustment of the image with virtually no distortion. This model is also equipped with motorized zoom and focus for further convenience and ease The 360° projection allows the projector to be positioned anywhere on the vertical axis. Fan speed can also be adjusted to help optimize results (depending on positioning). However, please note that when the projector is placed straight up or down, lamp life may be shortened. The four-point keystone correction allows the corners of the image to be independently adjusted to help ensure optimal image reproduction.
Lens Position Memory
Up to three different custom lens presets can be stored and memorized. Each preset includes information for a variety of lens settings such as lens shift, zoom, and focus. This is especially convenient for digital signage as this projector makes it easy to switch from one signage setup to another. The lens presets can also be of use in education as the presets can quickly change the settings from projecting on a screen to projecting on a blackboard.
Screen Color Correction and Test Patterns
The screen color correction enables you to fine-tune the colors of images based on the color of the projection surface. Adjustments can be made from Normal and Greenboard, as well as additional tuning for projecting onto virtually any other colored surface. Additionally, the projector features more than 25 test patterns to enable smooth installation and adjustment.
Advanced Professional Installation Settings
A variety of advanced installation settings provide added customization options for challenging areas. The built-in Edge Blending enables the projection of one seamless, large image from multiple projectors without the need of special software. Advanced registration allows independent position adjustment of the three primary colors (RGB) with high accuracy (0.1 pixel), ultimately reducing blurred colors or lines often projected at the edge of an image.
The REALiS 4K501ST includes two HDMI 2.0 and four DVI inputs that permit various input options, with support for single, stripe, and cross configurations. The two HDMI 2.0 inputs support HDCP 2.2 encryption to ensure the latest compatibility and help transmit 4K content, such as Blu-ray at 60 Hz over a single cable, offering practicality and convenience for film and TV usage, corporate, education, government, and more.
Compatibility with Crestron, AMX Device Discovery, and Extron helps ensure seamless integration into most systems, infrastructures, and network management. Support for PJLink also makes it possible to control and monitor the projector over a network—this feature is ideal for observing lamp hours, usage, and much more.
Low Power Consumption and Simplified Maintenance
When in Presentation Mode and the lamp set to Full Power, the power consumption of the REALiS 4K501ST is 0.12W per lumen (600W/5000 lumens). The projector offers multiple power management settings that allow the user to preset standby durations, execute power operations, and auto-assign functions to the power button. The design of the 4K501ST allows for simplified maintenance. Air filters and the lamp can be replaced without needing to uninstall the ceiling-mounted projector.
