Canon REALiS 4K501ST 4K Short Throw Projector

The REALiS 4K501ST brings ultra-high definition Canon 4K to the most demanding applications, from simulation and high-tech design to big-scale museum display, detail-rich film and TV, government-grade presentation and more. Audiences can experience images and video with extreme precision, natural fluidity and faithful color – all at a resolution that’s higher than 4K digital cinema.

Native 4K Resolution (4096 x 2400) Provides Immersive, Highly Detailed Images

Eye-opening 4K resolution produces incredibly detailed, high-impact images that are significantly sharper and more true to life than lower resolutions. 

At 4096 x 2400, Canon’s 4K resolution generates a bigger, richer picture made up of more than 9.8 million pixels – higher than the Digital Cinema Initiative (DCI) standard for 4K cinema (4096 x 2160) and more than QFHD (3840 x 2160), the resolution standard for 4K TV. When compared to popular Full HD (1920 x 1080), this projector’s native resolution produces more than four times the resolution. 

This high resolution can help in a variety of applications ranging from viewing highly detailed works of art in a museum or gallery, to producing highly accurate video and images with a wide depth-of-field to get as close as possible to a real life experience via a simulation system.

Canon 4K

Up to 5000 Lumens and 3000:1 Contrast Ratio Delivers Bright, Engaging Images

This projector projects bright 5000 lumen images with up to a 3000:1 contrast ratio that helps ensure deep blacks, bright whites and outstanding color. The results are images with crisp depth and dimension, and amazing color accuracy, which is critical to those with discerning needs.

Compact and Lightweight Design with 1.0–1.3:1 Shorter Throw Ratio for Application Flexibility

Canon’s cutting-edge 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 (just 0.76 inches), the projector is incredibly compact while delivering outstanding performance. At a height of 6.9 inches, width of 18.5 inches and weight of 39.6 pounds, it’s smaller and lighter than many others. In addition, its shorter throw ratio of 1.0–1.3:1 means a 10-foot wide image can be projected from an approximate distance of only 10 feet away, allowing for large images in tight spaces.


Size: 18.5" (W) x 6.9" (H) x 21" (D), Weight: 39.6 lbs.

LCOS Technology with AISYS-enhancement Offers Seamless Images with Exceptional Color Reproduction

The exceptional imaging performance of this projector starts with Canon's proprietary AISYS (Aspectual Illumination System) Optical Engine, which utilizes advanced light management technology to maximize the contrast and brightness benefits of the projector's LCOS (Liquid Crystal on Silicon) display panels, which deliver superior reflectivity and durability while accomplishing high luminance. The LCOS panels are relatively small in size, allowing for an overall compact projector that delivers high-resolution and high-quality results. With Canon’s AISYS-enhanced LCOS technology the pixels are close together, producing images that are virtually seamless, where with other technologies there may be grid lines visible from their larger spaces between pixels. The result with this projector is an immersive 4K resolution picture with crisp detail and true-to-life color.

Specialized Genuine Canon Optics Provide Exceptional Image Quality with Minimal Image Distortion and Consistent Brightness Throughout the 1.3x Zoom Range

Drawing on Canon’s advanced optical expertise, the specialized 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 renowned L-series EF camera lenses, which are highly regarded among professional photographers as many of the industry’s finest. The lens itself features a multitude of sophisticated 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 F2.6 as well as a new Marginal Focus feature allow images to be rendered highly accurately onto a variety of curved surfaces. Where other projectors may distort or bow at the edges, Canon’s optical technology keeps the image periphery extremely straight with a significantly low TV distortion. This results in beautiful images with smooth edges. The Marginal Focus feature facilitates projection on spherical surfaces. With the Marginal Focus feature the focus of peripheral areas can be adjusted while maintaining center focus. 

With the Genuine Canon Optics of this projector, brightness remains virtually consistent at 5000 lumens*1throughout the 1.3x zoom range, resulting in images that remain clear, strong and color-true whatever the projection distance within the zoom range.

Consistent Brightness

Consistent Brightness: Virtually no light is lost when changing lens position, meaning brightness is consistent throughout the zoom range and images remain sharp, clear and highly realistic.

Dual Image Engines Execute Highly Complex Image Processing for Uncompressed 4K 60p Playback and Upscaling of Non-4K Content

Canon’s advanced, powerful dual image processing engines produce exceptional 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, making them more realistic and impactful. 

4K Video Playback at Up to 60p: Smoothly reproduces uncompressed 4K video at up to 60 frames per second for a natural, fluid feel and highly detailed, true-to-life content.

4K Video Playback at Up to 60p

Upscaling: Non-4K content will be maximized utilizing two upscaling technologies of BiCubic and Canon’s proprietary Shape Trace – which can detect contours of an image in a diagonal direction and performs interpolation, resulting in a stunningly smooth image.


Multiple Image Modes*2 including DICOM Simulation Mode*3 for Optimal Image Quality Reproduction

This projector includes pre-set Image Modes and additional customizable Image Modes to suit a wide range of user preferences and projection environments. 

Multiple Image Modes*2
Image Modes provide different variations of color reproduction characteristics suitable for the image type and projection environment. They include: 

Standard: Ideal for bright rooms, and when using content from computer screens or motion picture content.
Presentation: Ideal for somewhat bright rooms when text needs to be clear, such as when part of a video presentation. 
Dynamic: Ideal for rooms that are somewhat bright, and when showing motion picture content. 
Photo/sRGB: Ideal for projecting images from sRGB-supported digital cameras. 
Video: Ideal for rooms that are somewhat dark, and for video content.
DICOM Simulation Mode*3: Ideal for displaying medical images in non-diagnostic settings. Both Blue Base and Clear Base settings are supported.
