REALiS 4K6021Z

Interchangeable Lens LCOS Projectors

Item Code: 3693C002AB


Native 4K DCI Resolution of 4096 x 2160 Provides Lifelike, 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 2160, Canon's 4K resolution generates a bigger, richer picture made up of more than 8.8 million pixels, meeting the Digital Cinema Initiative (DCI) standard for 4K cinema as well as the QFHD standard resolution (3840 x 2160) for 4K TV. In comparison to popular Full HD (1920 x 1080), the REALiS 4K6020Z laser projector's native 4K resolution produces 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.
The REALiS 4K6020Z projects clear, bright images at up to 6000 lumens with a contrast ratio of up to 22,000:1 when the Dynamic Contrast function is used – and with a native contrast ratio of up to 4000:1*2. This helps ensure deep blacks, bright whites and outstanding color, clarity, depth and dimension for high-quality images. *2 All white, all black. When Iris function is set to “Close 9”.
The projector's laser light source provides up to 20,000*4 hours in standard use of continuous, reliable, high-quality projection. The hours of operation can be nearly doubled when utilizing the Long Duration modes to up to 20 times longer than a conventional lamp's life. Because there is no lamp to replace, operation is virtually maintenance-free with minimal downtime, which is a key consideration for challenging and hard-to-reach installations. This keeps running costs relatively low when looking at the total life of the product. Other advantages of the laser light source include: Fast Boot Function When Fast Boot Function is set to ON, the startup time is reduced to virtually 2 seconds the next time the projector is started from a standby status. Omnidirectional Projection*5 Because this projector uses a laser light source instead of a conventional lamp, it can be installed at any angle on a 360° axis facing in any direction. A Menu Rotation function also enhances portrait projection, allowing adjustment of the angle of the projector's menu up to 90° left and right. Wider Color Gamut Because the laser light source produces a wide range of colors, the REALiS 4K6020Z covers 99.9% of the sRGB color space to deliver millions of colors. Quiet Modes Quiet Modes reduce the volume of projector operation to around 29 dB for more silent performance to reduce any potential of interfering with audible content.

*4 This is an estimated value. Actual hours may vary depending on usage and environment. This is not a guarantee of the life span of individual laser diodes.
*5 Air vents should not be blocked. Install in a stable and safe manner.
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, delivering superior reflectivity and durability while accomplishing high luminance.

Canon's LCOS panels are relatively small in size, allowing for an overall compact projector that delivers high-resolution and high-quality results. With the LCOS panels, 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 exceptional 4K resolution picture with crisp detail and true-to-life color.
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 reproduce uncompressed 4K video at up to 60 frames per second for a natural, fluid feel and highly detailed, true-to-life content. 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.
The REALiS 4K6020Z supports High Dynamic Range (HDR), exhibiting bright highlights and deep blacks for a wider dynamic range. The wider dynamic range expands the contrast and the color, both extremely important factors when it comes to image accuracy. Combined with highly detailed 4K resolution, this helps provide the ultimate viewing experience.
Periodical calibration ensures maximum color and brightness performance. Canon's internal sensors make this process simple, adjusting gamma and brightness back to the original specification. Gamma Restore This calibration setting measures the RGB luminance of the projector's LCOS panels and corrects the gradation to the factory default setting*11. Light Source Calibration This function corrects the hue according to the aging variation in the laser output. The function automatically runs when the projector is shut down. However, users can manually execute this after 30 minutes of operation have passed.

*11 This function should only be used when variation in gradation properties or achromatic colors become noticeably different from time of purchase.
The 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

Color Adjustments Color Level Color Balance Color Temperature Gain (RGB) Offset (RGB)

Advanced Image Adjustments These adjustments provide greater flexibility to professional users with more options to adjust the image as desired. These settings include:
Dynamic Contrast: A function that determines the brightness of scenes by looking to the histogram of the image signal and then controls the light source and gradation performance based on that information. This function, when applied, expresses up to a 20,000:1 contrast ratio—producing clear contrast even in dark scenes. Frame Lock*12: In order to prevent synchronization errors caused by frame rate gaps between the input source and the LCOS panel drive, this feature synchronizes the input signal of different display devices with the projector resulting in smooth image playback. Colorimetry: Three color standard presets (BT.709, BT.2020 and Auto) enable users to optimize the color output of the image content. Ambient Light: This technology allows the user to select the color temperature and other characteristics that are in the active environment. Random Noise Reduction: This feature eliminates minute noise that may appear in the image. Digital Noise Reduction: This feature eliminates block noise that may appear when playing back compressed digital images and "mosquito noise" that may appear in a dot pattern near the edges. Dynamic Gamma: When applied, this feature analyzes individual areas of the image for specific, independent contrast adjustment so light and dark areas do not appear over or under exposed. Memory Color Correction: This Canon technology can be used to enhance skin tones and other color features for rich, vivid results that look striking to the human eye. 6-Axis Color Adjust: This technology lets users fine-tune the hue, saturation and brightness of each of the primary and secondary colors, providing a high degree of control that can make each projected image a "masterpiece". Fine-tune Gamma: This setting enables the adjustment of gamma curve, allowing the user to adjust white, red, green and blue.

*12 Please see user manual for supported frequencies this function can be utilized with.
The projector includes Canon's latest Motion Blur Reduction*9 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, Weak and Off) are included for flexibility, with each depending on the level of movement and type of video content. *9 When motion blur reduction is activated, brightness will be affected.
Operating Mode Four work modes allow adjustment to maximize projector life. Normal: Brightness is set by Light Mode settings. Fixed Brightness: Brightness does not change due to aging. Maximum brightness is set at 20–70% of initial brightness. Longer Duration 1: To be used for a long period of time. Maximum brightness is 20–70% of current brightness. Longer Duration 2: Used for longer periods of time. Maximum brightness is set to 20–50% of current brightness.

Furthermore, light emission in the following ranges can be adjusted in the Brightness Level function when Operating Mode is not set to Normal. Operating Mode Light Source Output Fixed Brightness 20% – 70% Longer Duration 1 20% – 70% Longer Duration 2 20% – 50% * Values for non-standard light source output and brightness are approximations.

Light Source Mode To reduce projector noise and cooling fan speed, different light modes can be selected. Setting Light Source Output Brightness Noise Level Normal 100% 6000 lumens 38 dB Quiet 1 70% 3600 lumens 33 dB Quiet 2 50% 2400 lumens 29 dB * Values for non-standard light source output and brightness are approximations.

Position Lock This feature ensures specific installation settings such as Image Flip, Keystone Correction and Lens Position are not accidentally disturbed, saving users time from the inconvenience of reconfiguration. Menu Rotation This feature enhances portrait projection, allowing adjustment of the angle of the projector's menu up to 90 degrees left and right. Sensors within the projector sense the angle of the projector and flip the image accordingly in increments of 90 degrees. 4-point Keystone Correction
Allows the corners of the image to be independently adjusted to help ensure optimal image reproduction. Lens Position
Up to 3 different custom lens presets can be stored and memorized. Each preset includes information for a variety of lens settings. Zoom Focus Lens Shift Lens Shift Mode Keystone 4-point Keystone Correction Screen Color Adjustment (Normal, Blackboard, etc.) Reduction Zoom

This is especially convenient for digital signage as this projector makes it easy to switch from one signage set-up to another. The lens presets can also be of use in education where the presets can be used to quickly change the settings from projecting on a screen to the settings needed for projecting on a blackboard. Screen Color Correction
Enables users 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.
