Samsung wants to have a 576MP smartphone camera in four years

Samsung wants to have a 576MP smartphone camera in four years

After CPU clock cycles, the mobile numbers game has seemingly shifted to pixel counts. While it has been repeatedly proven that higher doesn't always mean better, that hasn't stopped manufacturers from flaunting large figures, especially in marketing materials. It doesn't really hurt if you have dozens or even hundreds of megapixels if you can cram that many in a sensor, but Samsung might be taking things to the extreme in a few years. Not satisfied with its recently announced 200MP sensor, it apparently wants to have more than twice that much by 2025.

Samsung ISOCELL HP1 brings a 200MP sensor to smartphones

Samsung ISOCELL HP1 brings a 200MP sensor to smartphones

Although higher pixel counts don't always translate to higher quality images, it sometimes never hurts to have more if you can afford it, especially since it looks good in marketing. For years now, Samsung has been pushing the envelope when it comes to the number of pixels a single mobile image sensor can hold, and it has just announced a new milestone with the 200MP ISOCELL HP1. Samsung also introduces the new ISOCELL GN5 promises upgraded autofocus with a more "normal" 50MP sensor.

New sensor creates electricity from urine and measures glucose levels

New sensor creates electricity from urine and measures glucose levels

Scientists from Tokyo University of science have created a new sensor designed to be fitted into diapers that generates the electricity it needs to operate directly from urine using a biofuel cell. While the device can generate the power it needs to operate using urine, it also measures glucose concentrations, helping caregivers monitor wearers for diabetes. Scientists say that glucose levels in urine are directly related to blood glucose levels.

Future OPPO phones will be using new under-screen camera and RGBW sensor

Future OPPO phones will be using new under-screen camera and RGBW sensor

With the Galaxy Z Fold 3, Samsung officially joined the bandwagon circling around under-display cameras (UDC), alternatively called under-screen or under-panel cameras. It isn't the first to jump on it, though, with ZTE stealing the thunder by launching the first UDC-equipped phone last year. OPPO, however, was also one of the first to actually get its R&D engine running to create the perfect under-screen camera implementation.

While OPPO isn't announcing yet when that will finally be available in a smartphone, it is revealing some of the imaging technologies that will be arriving on smartphones in the next six to seven months.

Intel RealSense camera business is winding down

Intel RealSense camera business is winding down

Once upon a time, Intel was so big and so successful that it could afford to venture into areas and businesses that were only remotely related to its core silicon business. That included, for a time, wearables as well as computer vision hardware like cameras and LiDARs. Intel is still big, but its dominance is continually challenged on almost all fronts. Refocusing on its strengths, Intel has chosen to also refocus its resources away from failing businesses, like its years-old RealSense division that produced rather interesting products and demos around computer vision.

Pixel 6 camera could be a huge upgrade in more ways than one

Pixel 6 camera could be a huge upgrade in more ways than one

Google seemed to have beaten Apple at being stingy when it came to camera upgrades. Ever since the OG Pixel half a decade ago, Google barely upgraded the line's main camera, preferring to rely on software magic to compensate. As indicated by its new design and new processor, the Pixel 6 is a marked departure from its predecessors. A teardown of Google's Camera app for Android 12 now suggests that the same will apply to the phone's main camera in a very big way.

Galaxy S22 could come with a 50MP RGBW camera sensor

Galaxy S22 could come with a 50MP RGBW camera sensor

The battle over the best smartphone for photography is far from over, especially with the Huawei P50 Pro once again tilting the tides in the embattled Chinese company's favor. Smartphone cameras have gotten larger, more sophisticated, and sometimes a little bit insane, but some improvements don't always come from upcoming or future technologies. Samsung's phones have shown arguably positive performance in that arena, and its next Galaxy S22 flagship could be taking lessons from the past and use an RGBW imaging sensor to improve its chances in the future.

Samsung ISOCELL Auto 4AC is an imaging sensor built for vehicles

Samsung has announced a new automotive image sensor called the ISOCELL Auto 4AC. The imaging sensor delivers 120-decibel high dynamic range and LED Flicker mitigation specifically for surround-view monitors or rear-view cameras. The sensor supports HD resolution of 1280 x 960. Samsung notes that the new sensor is the first imaging solution optimized specifically for automotive applications.

Galaxy S22 might not use a 200MP camera from Samsung and Xiaomi

Galaxy S22 might not use a 200MP camera from Samsung and Xiaomi

Smartphone cameras are getting ridiculously large in terms of megapixel count, far surpassing the imaging sensors you'd find even on professional digital cameras. "More" doesn't always mean better, as some phone manufacturers have proven over the years, but that hasn't stopped them from still putting out mobile cameras with triple-digit megapixel counts. Samsung and Xiaomi have even been rumored to be working on a 200MP ISOCELL sensor that might not be used in Samsung's own Galaxy S22 next year.

Samsung ISOCELL JN1 shrinks a 50MP sensor down to 0.64 micropixels

Samsung ISOCELL JN1 shrinks a 50MP sensor down to 0.64 micropixels

As smartphone cameras start boasting more and more pixels, they've also started to become bigger and bigger. Just like with processors, the challenge for imaging sensors is to cram as many photodiodes on a small surface without enlarging the size of that surface. That's the achievement that Samsung is boasting about with its new ISOCELL JN1 that is able to cram 50 million pixels in the size of a 1/2.76-inch format sensor. Whether it's able to take better or similar quality photos as Samsung's larger 50MP sensors, however, remains to be tested.

Injectable wireless chip to monitor body processes invented at Columbia University

Injectable wireless chip to monitor body processes invented at Columbia University

Engineers at Columbia University have created a tiny, wireless, and injectable chip used to monitor body processes powered by ultrasound. The device is said to be the smallest single-chip system that is a complete functioning electronic circuit. The implantable chip is visible only under a microscope and leads the way towards developing chips that can be injected into the body using a hypodermic needle.

Galaxy Fold with under-display health sensors seen in patent

Galaxy Fold with under-display health sensors seen in patent

Before smartwatches became the portable health labs that they are today, smartphones were the ones that bore some of the sensors and algorithms needed for checking one's health. Samsung's phones, in particular, once had heart rate monitors and even blood oxygen tracking that it has removed in its most recent models. That, however, doesn't mean that Samsung has given up that idea, and, apparently, it was toying with the possibility of putting such health sensors beneath the screen of a foldable phone.
