Luuv video camera stabilizers finally make it to the market

22 Feb

Three years after launching its Indiegogo funding campaign German start-up Luuv has announced it is ready to begin open sales of its video camera stabilization devices. The company has serviced all its backers and is now selling its solidLuuv, ultraLuuv Action and Action Gimbal to the public.

Designed for filmmakers using small cameras such as GoPro action cams and smartphones, the ultraLuuv Action combines the company’s solidLuuv and Action Gimbal to provide both mechanical and electronic stabilization. Luuv says the setup offers 2x 3-axis stabilization, with the 3-axis mechanical stabilization of the solidLuuv alongside the 3-axis electronic stabilization produced by the rechargeable-battery powered Action Gimbal. The gimbal has four modes that allow panning actions, panning and tilting and for the head to be locked or inverted.

On its own the Action Gimbal can only cope with 150g weight, so the ultraLuuv Action is limited in the same way, but the solidLuuv can deal with kit weighing up to 500g.

The ultraLuuv Action is priced €599 (about $ 630), while the solidLuuv is €349 (about $ 370) and the Action Gimbal is €269 (about $ 280). For more information see the Luuv website. Shipping is free within Germany, but looks like an additional €35 (about $ 37) to the US.

iPhone 8 front camera rumored to capture 3D images

22 Feb

Last week it was reported that Apple might be replacing the Touch ID fingerprint reader with 3D facial recognition on the top-of-the-line model of the upcoming iPhone 8 series. Now these rumors have become more substantiated by another report by Apple analyst KGI Ming-Chi Kuo which has been published today and obtained by 9to5Mac.

According to the report, the upcoming iPhone top model, which is also expected to feature an OLED display, will come with a technology that combines 2D images captured by the front camera with depth data from an infrared module to record 3D information. The application for this new front camera technology could include facial recognition, iris recognition, and 3D selfies. It could also be used in innovative games that allow for replacing a 3D-avatar’s head with the head of the phone’s user or for augmented reality purposes. 

If the report is correct, the infrared transmitter will use vertical-cavity surface-emitting laser technology from a company called Lumentum and the IR receiver will be manufactured by Foxconn/Sharp. The front camera will be supplied by Sony. The hardware will be controlled by algorithms developed by PrimeSense, a company that Apple acquired in 2013. The system works by emitting invisible IR light and then detecting the signals that are reflected by objects in the proximity using a 1.4 megapixel IR receiver. The resulting system will have much more advanced depth-sensing capabilities than the existing iPhone 7 Plus dual rear camera that uses the optical parallax offset of its two lenses to determine the distance to objects in the scene. 

As usual, there is no guarantee the rumored feature will actually materialize in the final product. That said, it certainly looks as if Apple is preparing something special for its 2017 iPhone generation. Unfortunately, another rumor is saying the flagship model might set you back upwards of $ 1000.

Neural network converts Game Boy Camera images into color photos

21 Feb

We’ve seen a lot of research lately that uses neural networks to upsample low resolution images and the results have been impressive – even a little creepy. Google recently showcased a system that can turn a low resolution 8×8 input image into a 32×32 sample that’s remarkably close to the original image. Inspired by recent breakthroughs, research engineer Roland Meertens found another application for neural networks – one that’s highly relevant to our interests. He created an application that turns low-res, monochrome Game Boy Camera images into photorealistic color images.

Original images in the center, Game Boy-ified images on the left and image generated by neural network on the right


A network must be trained, and training means feeding it input images. To create a training data set, Meertens gave some ‘real life images’ a Game Boy Camera treatment by re-creating them in four shades of black. By comparing the Game Boy-ified images with the originals, the network is ‘taught’ how to convert the images to color. With the network trained and ready, Meertens began testing it on celebrity photos as well as images from the Game Boy Camera (including the game’s mysterious character at the top of the page).

Finally, Meertens uses the application on an image taken with the Game Boy Camera. Naturally, it should be a selfie, as it is here. If you have all of the necessary components, taking a photo with the Game Boy camera is easy. Getting it onto your computer is another story. Lacking a specialized cable, Meertens did his best to photograph the Game Boy screen. As a result the lighting is slightly uneven, which affects the output from the network, but the re-creation is still pretty darn cool. Our hats are off to him.

Blackmagic Web Presenter makes it easy to use any camera for live webcasting

12 Feb

Have you ever wanted to use your DSLR, mirrorless, or other high quality camera for live video streaming on platforms like Facebook Live, Skype, or Periscope? If so, you’ve probably discovered how challenging it can be to get some of these programs to work with something other than a webcam or smartphone camera.

 
This week, Blackmagic Design announced what appears to be a great solution to this problem. The Blackmagic Web Presenter is a device that captures video from any camera and relays it to your computer, making the video appear as though it originates from a webcam. Blackmagic claims that it should work with Mac, Windows, Linux, and even Chromebook computers automatically without installing any drivers.
The Web Presenter supports video output from cameras up to Ultra HD resolution. The device scales output signal down to 720p for web streaming using Teranex conversions, which should result in very high quality scaling. It supports both HDMI 2.0 and 12G-SDI connections, and also includes XLR and component audio-in.
 
If you’ve longed to use your favorite DSLR or mirrorless camera instead of a mediocre webcam or smartphone for live webcasts, the Web Presenter looks like it could be a great option.
 
The Blackmagic Design Web Presenter is available now for $ 495.
 
Press release:

Blackmagic Design Announces New Blackmagic Web Presenter

Now it’s possible to make any SDI and HDMI video source appear as a USB webcam for high quality streaming on the internet.

Fremont, California – February 6, 2017 – Blackmagic Design today announced the new Blackmagic Web Presenter, which allows customers to use their professional SDI and HDMI video sources with streaming software and services such as YouTube Live, Facebook Live, and more.

Featuring 12G-SDI and HDMI connections, Blackmagic Web Presenter will down convert any SD, HD and Ultra HD sources and make them look like a 720p USB webcam. As all streaming software works with webcams, Blackmagic Web Presenter also makes it easy to work with any streaming software, but with dramatically higher quality. Streaming in 720p ensures customers get the quality of HD and a 16:9 aspect ratio, but with very low data rates so uplinking streams to the internet is easy from any computer.

Blackmagic Web Presenter can also live switch programs using its built in 2 input production switcher when the optional Teranex Mini Smart Panel is installed, making it a full live production solution for location broadcast.
Blackmagic Web Presenter is available now for US$ 495 from Blackmagic Design resellers worldwide.

Blackmagic Web Presenter is the fastest and easiest way to get high quality video directly on the web for a new generation of web broadcasting. It replaces expensive and hard to set up dedicated streaming encoders and lets customers or broadcasters use professional cameras to stream high quality video through their favorite software and websites. Because Blackmagic Web Presenter looks like a simple webcam, any webcam compatible software will be able to capture this USB video and audio from any broadcast quality source without the need for additional drivers.

Blackmagic Web Presenter is designed for both the high end broadcaster as well as a new generation of web broadcasters. Traditional broadcasters can use Blackmagic Web Presenter to get content online quickly to a global audience from any location.

Pixlplay turns a smartphone into a big, durable ‘camera’ for kids

11 Feb

A new Kickstarter project aims to make digital photography easily accessible to children, with a product that is relatively inexpensive and durable. Called Pixlplay, the device is essentially a smartphone case shaped like a classic 35mm film camera, and it includes moveable dials and knobs, as well as a functional shutter button.

The Pixlplay case features a pair of rubber handgrips, adjustable clamps for accommodating phones of various sizes, and a 3.5mm cable that plugs into the phone’s audio jack to power the case’s shutter button. Photos can be snapped through the phone’s built-in camera app using the shutter button, or by touching the phone’s screen (a touch-sensitive screen protector is built into the case). Camera settings can also be adjusted by touching the screen.

Pixlplay features child-resistant dual latches to help prevent children from removing the smartphone, which is offered some protection from drops and dirt while inside the case. Included activity sheets, meanwhile, teach kids the basics about photography, while a dedicated iOS photo editing app allows kids to add frames and silly stickers to their photos. There doesn’t seem to be an Android app, however the case itself can be used with Android and Windows phones.

The case’s maximum phone dimensions are 5.59 x 2.95 x 0.374 in / 142 x 75 x 9.5mm, making it suitable for the iPhone 7 and older models, as well as most Android smartphones. The product’s maker, Pixl Toys, is currently seeking funding for Pixlplay on Kickstarter, where it has raised about $ 13,000 of its $ 25,000 goal. A single Pixlplay camera is being offered to backers who pledge at least $ 25, with shipping estimated to start in June.

Panasonic’s new organic CMOS sensor won’t be in your next camera but it’s cool anyway

10 Feb
Organic chips, but not the kind with sea salt. On the left the sensor is used in plain old visible light mode. By changing the electric charge applied to the chip, visible and near-infrared light are captured simultaneously, shown on the right.

Panasonic has been developing organic sensors for a while now and has just announced a new breakthrough: an organic CMOS chip that can capture visible and near-infrared (NIR) light simultaneously without sacrificing resolution.

There are sensors available now that can image both near-infrared and visible light, but they sacrifice one out of every four pixels to NIR capture. As a result, resolution of the final image suffers. Panasonic’s new chip makes use of two organic layers: the top layer is sensitive to visible light and the bottom layer is sensitive to near-infrared light. By changing the voltage applied to the layers, it’s possible to choose whether the lower layer is active or not. This means it can switch between visible and visible+NIR imaging frame by frame, which is useful in machine vision applications where subjects may be moving quickly.

The image on the left is recorded with color imaging mode, the right shows the scene in NIR imaging mode. The new sensor could be used for night vision and surveillance.

Alternatively, it allows for the creation of security cameras that capture visible light during the day then switch to visible+NIR for a full-resolution ‘night vision’ mode after dark.

It’s great news too if your job relies on checking things that aren’t visible to the human eye, like checking things on an assembly line that are out of sight, but this sensor is unlikely to ever be used in a consumer digital camera. Still, it’s promising to see that Panasonic’s experiments in creating chips made of something besides silicon are paying off.

If nothing else, separating the capture medium from the readout mechanism makes it easier to implement a global shutter design, since the light-sensitive layer can be switched on and off independently, rather than being constrained by the (sequential) read-out process.

This camera is made of 32,000 drinking straws

10 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_2231851679″,”galleryId”:”2231851679″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Looking for a craft project to tackle this weekend? It might be an undertaking, but it turns out if you put 32,000 drinking straws together in a wooden box, voila – you’ve got a camera. At least, that was the starting point for a collaboration by artists Michael Farrell and Cliff Haynes. Over the course of several years they worked on iterations of the Straw Camera, a project that combined their love of sculpture, photography and innovation.

The first versions of Straw Camera used 10-inch black drinking straws, each one with roughly an F127 aperture. The pair began photographing still life, but early results were mixed. Haynes describes his frustrations with images from the first version of the camera:

‘I was slightly disillusioned by the output from the initial camera, the straws were never going to be even, the camera had it’s own signature, changing slightly each time a few more were added as they settled in the box. I thought a similar, more even field could be obtained using corrugated black plastic protective floor sheeting instead of straws.’

Later versions of the Straw Camera used a more predictable, easier-to-work-with corrugated plastic layer. Its creators moved past still life and focused on creating portraits with the camera, embracing the pointillist qualities of its output as a contrast to the ubiquitous, high-resolution selfie. Says Haynes:

‘…a Straw Camera image of an individual, with its engineering projection and disappearance of the subject into the near fog of visual capture, gives the viewer a glimpse of just how transitory perception is.’

You can see some samples of Haynes and Farrell’s work above. if you’re in London you can also check out their work in person at Slade Research Centre, University College London from February 16-19 from 12-5pm. A book of Straw Camera images is available on Blurb.

Digital camera inventors awarded with Queen Elizabeth Prize

04 Feb
Dr. Tompsett, Prof. Teranishi and Prof. Fossum at the ceremony, image: Queen Elizabeth Prize

This year’s 1 million Pound Queen Elizabeth Prize has recognized the work of some of the key scientists in the creation of digital imaging sensors. The award is shared by British-born Dr Mike Tompsett, Professor Nobukazu Teranishi from Japan, and Professor Eric Fossum and George Smith from the US.

George Smith and Willard Boyle, who are now both deceased, first had the idea for CCD sensors at Bell Labs in 1969, but it was their colleague Dr. Tompsett, who saw the potential of the technology in imaging. The first digital color photo, of Tompsett’s wife Margaret, appeared on the cover of Electronics Magazine. 

Professor Teranishi is the inventor of the pinned photodiode (PPD), which is a more efficient photodiode than previous variants. He undertook the work at NEC Corporation in Japan in 1980.

Eric Fossum worked in the 1990s at the NASA and Caltech’s Jet Propulsion Lab. His goal was to miniaturize digital cameras to reduce the payload of spacecraft. His work resulted in the development of CMOS sensors which can be found in most modern consumer digital cameras.

Digital imaging, together with other forms of digital technology, has transformed the world, and every day billions of digital images are captured by billions of devices, ranging from professional TV cameras to tiny imaging units in autonomous vehicles. At the time of their inventions the scientists might not have foreseen the scale of the impact of the technology but they are certainly more than deserving of this year’s award.
