The REALiS 4K500ST 5000-Lumen 4K LCOS Projector from Canon supports 4K resolution that produces detailed, high-impact images that are sharper and more true-to-life than lower resolutions. At 4096 x 2400, the 4K500ST's resolution generates a bigger, richer picture made up of more than 9.8 million pixels. This high level of resolution can help military, flight, and other types of simulators to produce highly accurate video and images with a wide depth-of-field, allowing for a truer real life visual experience.
Large dramatic displays and panoramas can be created using the built-in Edge Blending function of multiple projectors. Accurate color reproduction and professional adjustment options help amplify the impact by providing sharp images that can suit specific imaging needs.
LCOS Technology with AISYS-Enhancement
Canon's AISYS Optical Engine (Aspectual Illumination System) maximizes the light source and performance of the LCOS (Liquid Crystal On Silicon) panels to produce high resolution, brightness, and contrast. Where high-level detail and clarity is vital, 5000 lumens of brightness and a contrast ratio of up to 2500:1 help provide a high-quality image. In addition, three 0.76" LCOS panels create smooth, natural video and images with a fast response time when compared to other projection technologies. The result is a 4K resolution picture with crisp detail and true-to-life color.
The specialized 4K short focus wide zoom lens projects virtually distortion-free 4096 x 2400 resolution images. A throw ratio of 1.0-1.3:1 means a 10' wide image can be projected from an approximate distance of only 10' away. 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 significantly reduce chromatic aberration, curvilinear distortion, ghosting, and flare to create sharp and clear images in a compact size. A deep depth of focus at f/2.6, as well as Marginal Focus feature, allow images to be rendered highly accurately onto a variety of curved surfaces. Even at the edges, Canon's optical technology keeps the image periphery extremely straight with a significantly low TV distortion. This results in images with smooth edges. Brightness remains virtually consistent at 5000 lumens throughout the 1.3x zoom range, resulting in images that remain clear, strong, and color-true, whatever the projection distance.
Image Processing Technologies
With the REALiS 4K LCOS projector, you can smoothly reproduce uncompressed 4K video at 60 or 30 fps, for a natural fluid feel and highly detailed true-to-life content. Non-4K content can be displayed by utilizing two scaling functions of BiCubic and Canon's Shape Trace, which can detect contours of an image in a diagonal direction and performs interpolation, resulting in a smooth image. When Dynamic Gamma is applied, the feature analyzes individual areas of the image for specific, independent contrast adjustment so light and dark areas do not appear over or underexposed. Memory Color Correction can be used to enhance skin tones and other color features for rich, vivid results that look striking to the human eye.
Motion Blur Reduction Function
Advanced image adjustments include 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 this function is activated, the projector's brightness is affected.
Low Frame Delay
Effective simulation and training depends on realistic video with low latency, with images that refresh as quickly as possible with minimal lag time. A relatively small frame delay helps to create an immersive, life-like experience. Response times are fast, so if a trainee pilot activates a cockpit control, for example, the corresponding video picture will respond quickly for a real-life look and feel.
The Marginal Focus feature helps ensure that images projected onto a spherically domed surface are kept in focus right up to the edges. With the 4K500ST, the built-in marginal focus allows for adjustment of focus on domed screens.
Advanced Professional Settings
A variety of advanced installation settings provide added customization options for challenging installation areas. Motorized lens shift makes it possible to easily adjust the vertical and horizontal positioning of the projected image. Four-Point Keystone Correction allows the corners of the image to be independently adjusted to help ensure optimal image reproduction. 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.
Multiple Image Modes
Select from six different pre-set image modes, as well as three customizable image modes, to best optimize quality based on content type and projection environment. Pre-set image modes are Standard, Presentation, Dynamic, Photo/sRGB, Video, and DICOM Simulation mode.
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 projector positioning).
Industry-standard connectivity on the 4K500ST includes four DVI inputs and two HDMI inputs that permit various input options such as supporting single, stripe, and cross configurations.
Crestron and AMX Device Compatibility
For extra control and seamless integration into existing systems, the projector is compatible with Crestron Room View, AMX Device Discovery, PJLink, and others.
Compact and Lightweight Design
Canon's optical design achieves 4K resolution and 5000-lumen brightness within an incredibly compact projector size. The innovative AISYS Optical Engine makes this possible by independently controlling light in both vertical and horizontal directions to achieve both high brightness and contrast. Combined with the small size of the LCoS panels, the projector is compact.
