Thank you for choosing Lume Pad (2020)

The original Lume Pad came out in 2020, and was a non-tracked "4V" device (4x4 views for a total of 16 views) glasses-free 3D Android tablet. After running the Leia Appstore for Lume Pad (2020) for four years, we're stopping support in July 2024, two years after we stopped selling the device. For your convenience, we will be providing download links to the final versions of Leia apps on Lume Pad (2020), and links to a few other popular apps, with no warranty or support, either express or implied. You will be using these apps at your own risk.

All links to Lume Pad app APKs are available at the bottom of this page.

What is Lume Pad?

Lume Pad is the world’s first Lightfield tablet. A crisp, comfortable 10.8-inch Lightfield display offering a no-compromise experience for the Android apps you know and love as well as a suite of apps that you can see in stereoscopic 3D with the naked eye without ANY specialized eyewear required.

If you’re a creator that wants to see your content in a new light, Lume Pad provides a beautiful medium to highlight your work.

Whether you’re designing buildings, developing games, creating 3D models in new ways, or even if you’re constructing a new take on medical visualization software: the Lume Pad is the tool for you. Pictures, videos, and 3D models. All elevated to the next level with Lightfield.

It all starts here with the Lume Pad and its powerful Leia app suite.

This guide will help you understand everything you can do with your Lume Pad.

Anatomy of the Lume Pad

The Lume Pad is a high-quality Android tablet with a chassis made of brushed aluminum. On the back of the device you'll find the Lume Pad and LitByLeia logos, the high-quality 3D camera, and the antenna window.

On the front of the device you'll find the front-facing camera, the ToF sensor, and of course, the DLB Lightfield display.

On the right side of the device you'll find the volume rocker and the lock button, and on the top of the device you'll find the USB-C charging port.

It all starts with the screen

At Leia, we’ve developed a single optical layer sculpted by nanotechnology that sits just underneath the LCD display to create the Lightfield effect, powered by what we call Diffractive Lightfield Backlighting (DLB).

With 2D content, the Lume Pad’s 10.8-inch screen projects out a bright 2560X1600 picture. When used for traditional Android apps, that 16:10 screen looks bright, sharp and, well, like a normal high-end Android tablet.

But when the DLB is activated, lights pass through it to create a dynamic Lightfield 3D effect. The light projects out four views simultaneously in 16 directions -- this is Lume Pad's Lightfield view mode. Unlike other 3D solutions, Lume Pad is brighter, thinner, can instantly switch between full-quality 2D and Lightfield 3D, and can be rotated to support every orientation while in 3D. Lume Pad is LitByLeia.

Our goal is to deliver our vision of how Lightfield can change the way we see art, engage in commerce, and affect the world.

Software for Lume Pad

LeiaLogin is a unified account system across Leia's Lightfield apps and select partner apps from the Leia appstore. It's required for Lume Link and LeiaPix.

LeiaPlayer is the one-stop shop for playing back 3D and Lightfield media. We call it LeiaPlayer, but really, this app does a whole lot more than simply play your Lightfield images and videos. It is a quick and powerful editing tool for your Lightfield images, gives you the power to convert 2D images and videos into 3D, and links directly to your smartphone's camera with Lume Link.

Download LeiaPlayer 3.3

LeiaPix is the biggest social network for 3D images ever with 100,000+ unique 3D and Lightfield images. Share your content — and connect — with an active community of fellow creators. Then export your creations to MP4, GIF... or even order Prints of your favorite shots as lenticular photos, straight from the app!

Download LeiaPix 2.6 LeiaTube let's anyone stream videos from their favorite streaming video platforms like YouTube and Twitch in Lightfield 3D.

LeiaCam takes Lightfield photos and videos at the press of a button. Photos are saved in Leia Image Format, which can instantly be sent to non-LitByLeia devices where they'll be seen in standard 2D, or to another LitByLeia device where they can be edited or viewed. Videos are saved as a high quality 4K per eye SBS, so they can be easily edited on traditional NLE video editing software or viewed on legacy 3D devices.

Editing Tools

Depth Slider

• The Depth slider controls the disparity value of your image. As you move the slider up, you will perceive more depth

• Disparity is the difference in image location of the same 3D point when projected under perspective to two different camera views

• Perception of depth arises from the “disparity” of a given 3D point in your right and left retinal images

Focus Slider

• The Focus slider controls the convergence value of your image.

• As you move the slider up, more objects in your image will appear to be popping out of the front of the screen

• As you move the slider down, more objects in your image will appear to be moving backward behind the screen

• The convergence value is the point at which the left and right eye images align, which sets the location of convergence at the screen plane

• Objects in front of this point will appear to be in front of the screen and those behind will appear to be behind the screen

Bokeh Slider

• The bokeh slider controls the digital blur applied to background pixels that are located behind the convergence plane

• If you move the convergence slider to the very top, there are no pixels considered as behind the convergence plane, and thus aren’t part of the background

• Thus you won’t see any digital blur applied to those pixels, even if you move the Bokeh slider to the very top

Color

• These are primarily straightforward chroma editors that you will see in any mobile photo editing app

Brightness

• This will increase the brightness of all shadows and highlights in your image

• Your photo will look brighter overall as you move the slider up

Saturation

• This will increase the photo’s color intensity

• The colors in your photo will look more intense as you move the slider up

Contrast

• Contrast is the range of difference between different tones in a photo

• For black and white photos, contrast describes the difference between the darkest and lightest tones

• For color photos, contrast applies to how sharply colors stand out from one another

• As you move the slider up, bright colors will appear brighter

• As you move the slider down, dark colors will appear darker

Hue

• Adjusting the Hue slider to see shifts in the color values in your images

• You can radically alter your photos colors

• Smaller, more incremental adjustments can effectively reduce unwanted color casts and correct the photos white balance

Color Pop

• Color Pop will remove color from pixels considered as part of the background

• This makes the colors of objects in the foreground really standout

• This is the only feature in the Color section that makes use of the disparity map

Resize

• Simple tools for resizing and rotating your image.

• Note that if you crop an image down to a smaller size, its disparity and convergence values will increase, which will increase the depth sensation

Relighting

• This is where the artistic flavor gets added

• Tap any of the relighting presets, and you will have different lighting configurations added to your image.

• These lighting placements use the depth map to get placed into different parts of the image.

Filters:

• Apply styles to your images by selecting the preset filters.

• As with relighting, you can apply multiple presets to each image to create your own custom styles.

• Combine these filters with a bunch of relighting presets to make each image a unique work of art
