Samsung officially unveils 108MP ISOCELL Bright HMX mobile camera sensor

13 Aug

Samsung has officially announced the 108-megapixel camera sensor first teased by Chinese company Xiaomi last week. The new Samsung ISOCELL Bright HMX is the first mobile camera sensor that offers more than 100 megapixels, exceeding the company’s recently announced 64MP sensor. Samsung says the ISOCELL Bright HMX is the fruit of a ’close collaboration’ with Xiaomi.

The ISOCELL Bright HMX is the first mobile sensor to feature a 1/1.33″ size, according to Samsung, which says its Tetracell tech enables the HMX to ‘imitate big-pixel sensors’ for better quality 27MP images.

The 1/1.33″ format equates to around 9.6 x 7.2mm, which is around 40% smaller than a 1″-type sensor, but nearly 3 times larger than the 1/2.5″-type chips in the many of smartphones. The Tetracell design, much like Sony’s ‘Quad Bayer’ technology, places four pixels under each color of its color filter, making it easy to combine pixels to give better performance at 1/4 resolution, but also means additional processing needs to be done to attempt to replicate what a standard Bayer sensor would capture, if it had 108 megapixels.

Samsung’s ‘Tetracell’ tech makes low light (and, potentially, HDR) images easier to produce, but means processing is required to attempt to recreate what a standard Bayer sensor would have produced.

The sensor will be paired with what Samsung calls its Smart-ISO ‘mechanism,’ which it says toggles between a high ISO in darker environments and a low ISO in bright settings. This sounds like it may be describing a chip with more than one gain mode. Samsung claims this increases pixel saturation and the promise of ‘vivid photographs.’ The new HMX supports recording video at up to 6K 6016 x 3384 at 30fps.

Talking about the new product is Xiaomi President Lin Bin, who said:

‘We are very pleased that picture resolutions previously available only in a few top-tier DSLR cameras can now be designed into smartphones. As we continue our partnership, we anticipate bringing not only new mobile camera experiences but also a platform through which our users can create unique content.’

The company hasn’t yet revealed what those ‘new mobile camera experiences’ will be. Samsung plans to start mass-producing the ISOCELL Bright HMX in August.

Samsung Takes Mobile Photography to the Next Level with Industry’s First 108Mp Image Sensor for Smartphones

Samsung Electronics, a world leader in advanced semiconductor technology, today introduced 108 megapixel (Mp) Samsung ISOCELL Bright HMX, the first mobile image sensor in the industry to go beyond 100 million pixels. With the latest addition, Samsung will expand its 0.8?m image sensor offerings from its recently announced ultra-high 64Mp to 108Mp, a resolution equivalent to that of a high-end DSLR camera. Samsung ISOCELL Bright HMX is a one-of-a-kind mobile image sensor and is the result of close collaboration between Xiaomi Corp. and Samsung.

With over 100 million effective pixels enabling extremely sharp photographs rich in detail, the ISOCELL Bright HMX also produces exceptional photos even in extreme lighting conditions. Being the first mobile image sensor to adopt a large 1/1.33-inch size, the HMX can absorb more light in low-lit settings than smaller sensors and its pixel-merging Tetracell technology allows the sensor to imitate big-pixel sensors, producing brighter 27Mp images. In bright environments, the Smart-ISO, a mechanism that intelligently selects the level of amplifier gains according to the illumination of the environment for optimal light-to-electric signal conversion, switches to a low ISO to improve pixel saturation and produce vivid photographs. The mechanism uses a high ISO in darker settings that helps reduce noise, resulting in clearer pictures. For advanced filming, the HMX supports video recording without losses in field-of-view at resolutions up to 6K (6016 x 3384) 30-frames-per-second (fps).

“For ISOCELL Bright HMX, Xiaomi and Samsung have worked closely together from the early conceptual stage to production that has resulted in a groundbreaking 108Mp image sensor. We are very pleased that picture resolutions previously available only in a few top-tier DSLR cameras can now be designed into smartphones,” said Lin Bin, co-founder and president of Xiaomi. “As we continue our partnership, we anticipate bringing not only new mobile camera experiences but also a platform through which our users can create unique content.”

“Samsung is continuously pushing for innovations in pixel and logic technologies to engineer our ISOCELL image sensors to capture the world as close to how our eyes perceive them,” said Yongin Park, executive vice president of sensor business at Samsung Electronics. “Through close collaboration with Xiaomi, ISOCELL Bright HMX is the first mobile image sensor to pack over 100 million pixels and delivers unparalleled color reproduction and stunning detail with advanced Tetracell and ISOCELL Plus technology.”

Mass production for Samsung ISOCELL Bright HMX will begin later this month.

* Samsung first announced its ISOCELL technology in 2013, which reduces color-cross talk between pixels by placing a physical barrier, allowing small-sized pixels to achieve higher color fidelity. Based on this technology, Samsung introduced the industry’s first 1.0um-pixel image sensor in 2015 and 0.9-pixel sensor in 2017. In June 2018, Samsung introduced an upgraded pixel isolation technology, the ISOCELL Plus

Xiaomi teases future Mi smartphone with 108MP Samsung camera sensor

07 Aug

Xiaomi, the company often called the ‘Apple of China,’ has announced plans to pack a 108MP Samsung ISOCELL camera sensor into an upcoming Mi series smartphone model. The plan was teased by the company during the Xiaomi Future Image Technology Communication Conference in Beijing earlier today.

Xiaomi’s conference largely revolved around the Samsung ISOCELL GW1, a 64MP camera sensor that, based on Xiaomi’s past teases, is expected to launch in a future Redmi smartphone. The GW1 sensor is viewed as the next step up from the 48MP sensor found in a number of existing phone models, including the Redmi Note 7 and OnePlus 7 Pro.

In addition to detailing the 64MP sensor, Xiaomi announced that it will be the first company to use a Samsung 108MP ISOCELL 12032 x 9024 image sensor in a smartphone. The company didn’t reveal which model will pack the camera, but Ice Universe, a credible leaker on Twitter, claims the 108MP sensor will be available in the Xiaomi Mi Mix 4 model.

Samsung hasn’t released any information about this 108MP camera sensor at this time.

Makers of the Panono 108MP 360-degree camera filing for bankruptcy

24 May

German media reports that the founders of the company behind the Panono 360-degree ball camera have filed for insolvency proceedings at a court in Berlin, Germany. Unfortunately this means it’s very unlikely that the backers of the original crowdfunding campaign on Indiegogo will ever receive their camera. 

The small number of buyers who purchased a Panono through retail channels after the Indiegogo campaign could be affected as well. At this point it is unknown if the the Panono servers, which power the automatic stitching of the Panono’s 360-degree images, will remain functional for the foreseeable future.  

Initially things had gone well for the German start-up. The Indiegogo campaign generated 1.25 million dollars in 2013. However, it soon became obvious that the team had miscalculated the development time for the camera which back then only existed in prototype form.

The final product was due to ship in 2014 but instead there was only a second prototype in February 2015. A few months later first shipments were announced, but not to the project backers. Instead the cameras went to retail customers who paid a considerably higher prices. It appears at this point the company had already run out of money and was hoping to generate additional funds for mass production and eventual shipping to project backers. 

Now it seems this plan has not worked out either and remaining funds have dried up. We had the chance to test both a prototype and final product of the Panono camera and were quite impressed by the technology. 360-degree cameras are now much more widely available than in 2013 but none of the affordable models offer the Panono’s 108MP resolution and image detail.

Real world test: The Panono is a 108MP spherical camera

24 Jul

‘Uh, what is that thing?’

‘What is that thing?’ That’s the question I was asked pretty much every time I took the Panono out shooting. There is a lot of curiosity surrounding 360/VR content and my week spent fielding questions from curious onlookers as I dipped my toes into a new, more immersive photographic world is proof of that. In fact, only once did someone walk up to me and say “Hey I know what that is, its a 360 VR camera!” And it was a 12 year old child.

Damn know-it-all kids making us all look bad…

Yes, it can be tossed in the air to take a picture. 

So uh, what exactly is it? The Panono is the highest resolution 360-degree still camera currently on the market. A grapefruit-sized ball constructed of tough plastic, the Panono contains 36 separate cameras. Each camera uses a 1/4″ sensor (a bit smaller than the sensor likely found in your smartphone) and when the files are combined, the result is a 108MP 360-degree image that allows one to pan and zoom around the scene. 

Panono started off as a thesis project, but was later successfully funded via crowd-sourcing campaigns (DPreview field-tested an early version in 2013). Designed in Germany and constructed in Poland, everything about the camera is surprisingly frustration-free and the controls are intuitive. I say ‘surprisingly’ only because Panono is such a new company and good UI often takes time to get right. But once paired with a smart device, taking shots, processing  and sharing them is all a breeze. 

For optimal viewing, open the 360 in full screen mode. This image was shot using the HDR-setting, which combines a properly-exposed image with one exposed for highlights. 

The design 

The Panono only has a single button on the top. Holding it down for a second turns the camera on and off. When it’s switched on, the button can also be used to take images without the need for a smart device. However, for the best user experience, you’ll want to use the app to set up and control the Panono remotely from a phone or tablet. 

Around the periphery of the Panono’s one and only physical button is a glowing LED. It lights up when the camera is switched on and blinks whenever a photo is taken. If battery or internal space is getting low, part of the LED ring will illuminate red next to the corresponding symbol. While useful in dim conditions, the LED ring is near impossible to see in bright light.

There is a micro-USB port located at the very bottom of the camera for charging. It doubles as a mounting point for the Panono Adapter (to mount it on a tripod) and the Panono stick (a selfie stick). However when plugged into a computer via Micro-USB, the Panono is not discoverable. 

The app

Pairing with a device simply requires turning the Panono on and connecting to it via Wi-Fi. The password to connect is written directly on the side of the unit. Once connected, open up the app. At the bottom of the screen there are five icons. If you’ve properly paired the unit, green lines will appear above the camera icon (which is the shooting screen), indicating you are connected.

Most of the shooting controls are accessed via the center-most camera icon on the bottom. The app is also used to push images downloaded to your device to the cloud for processing. You can also view your processed 360s. 

Simply tap the green camera button to fire a shot. For more control over the camera’s exposure and color parameters, tap the gear symbol. 

To take images from within the shooting screen simply tap the green camera button bottom center. By default the camera will beep and blink when a photo is fired (the beep can be turned off). For more controls, tap the gear symbol in the lower right. There you can control a number parameters, like dialing in a white balance or specific exposure. I found the auto exposure and white balance modes largely worked fine for the majority of the places I shot. But it’s nice that those additional manual controls exist.

There is also a switch to toggle HDR mode on and off. If you’re mainly photographing static subjects, HDR mode is very useful. You can see an example of it on and off below:

The above image was shot as an HDR file, the one below was not.

The camera has 16GB of internal storage. Once an image is taken it is stored locally within the camera and a low-resolution un-stitched version of the image will appear within the app’s shooting screen for quick viewing. If you’re please with the preview, simple tap “download from camera,” and the files are transmitted to your device, but only temporarily – more on that in a moment.

It’s worth noting that if you are shooting a non-HDR image, there is a 10-sec black out time between when a shot has been fired and when an additional shot can be taken. When shooting an HDR image, that time gap is closer to 30 seconds. When the camera is ready to shoot again, the circle around the camera symbol/trigger button will turn from white to green. 

Once back in the comfort of a proper Wi-Fi connection open the “Task” screen (2nd icon from the right). There you’ll find all your transmitted 360’s. With the tap of a finger you can upload them to the Panono cloud where their servers do all the hard work of stitching and processing – you can simply sit back and make yourself a cocktail. In about 10 minutes, your 360s will appear in your Panono account where you can share them either via a direct link, iframe embed or Facebook/Twitter/Google+. It’s really that easy.
