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.

Galaxy S22 might skip the 3D ToF sensor yet again

Galaxy S22 might skip the 3D ToF sensor yet again

Samsung seems to be at a stage where it's rapidly playing around with its camera systems, quickly changing the formula based on what works and what doesn't. One of the puzzle pieces that has changed since last year has been its use of a 3D Time-of-Flight sensor or ToF which was present until the Galaxy S20 last year. Since then, however, the tech has been missing and it seems that next year's Galaxy S22 will miss out on it again, hinting at the end of its use at least for the time being.

Galaxy S22 might sport sensor-shift camera stabilization

Galaxy S22 might sport sensor-shift camera stabilization

Samsung's premium flagships have always been up there when it comes to camera performance but there are areas that could still use some improvement. Last year's Galaxy S20 Ultra was criticized for its autofocus problems and stabilization in smartphones is still undergoing constant evolution. The latest trend, started by Apple's iPhone 12 no less, seems to be shifting away from the once highly-popular OIS towards a sensor shifting strategy, a technology that Samsung is now rumored to be planning for its Galaxy S22 flagship next year.

Samsung ISOCELL 2.0 could cram more pixels into an image sensor

Samsung ISOCELL 2.0 could cram more pixels into an image sensor

Before it became a brand of its own, Samsung's ISOCELL was first a new kind of image sensor technology that aimed to solve the color crosstalk between pixels in a regular BSI (Backside Illuminated) sensor used in almost all digital cameras, including those on smartphones. That proved to be highly successful, at least in Samsung's view, and it is now taking it to the next level with ISOCELL 2.0. This new iteration promises not only to improve light absorption but, in the long run, also allow for smaller pixels to be packed in larger amounts on the same sensor size.

ZTE second-gen under-display camera might not fix its biggest flaw

ZTE second-gen under-display camera might not fix its biggest flaw

At MWC Shanghai, ZTE flaunted its next-gen technologies for under-display imaging sensors, including its second under-display camera or UDC. It remains the only smartphone maker that can boast of a commercial product that utilizes a screen with absolutely no cutout, but the ZTE Axon 20 5G can't really boast of producing great selfies because of it. There may have been hopes that its next UDC would address this problem but while it does get an upgrade, it doesn't actually address its most glaring issue.

Samsung 50MP ISOCELL GN2 brings Dual Pixel Pro AF, staggered-HDR

Samsung 50MP ISOCELL GN2 brings Dual Pixel Pro AF, staggered-HDR

When Samsung launched its first 100x Space Zoom camera on the Galaxy S20 Ultra last year, it was criticized for neglecting one important aspect of digital photography, the autofocus performance. Since then, Samsung has been careful to improve AF in its flagship phones and its next one might take it to the next level, or so Samsung boasts. Going beyond its own Dual Pixel brand of PDAF, Samsung is announcing a new 1.4μm 50Mp ISOCELL GN2 sensor that carries a Dual Pixel Pro version of its AF tech, along with other tricks that improve the sensor's low-light performance.

A new microfluidic sensor measures lactate concentration during exercise

A new microfluidic sensor measures lactate concentration during exercise

Researchers at the Tokyo University of Science have created a new wearable microfluidic sensor that can measure lactate concentration in sweat in real-time. Lactate is a compound present in sweat that's an important biomarker used to quantify exercise. Available wearable sensors are typically rigid devices that can cause skin irritation.

Nikon 1-inch stacked CMOS sensor boasts 1000 fps shooting

While smartphone makers are still playing the megapixel game, camera makers are looking into other aspects of digital photography that can still be improved. Nikon, for example, just boasted the development of a new stacked CMOS sensor that can shoot high-resolution images, up to 4K in fact, at a rate of 1,000 frames per second. While that a\lone might already be impressive, it isn't the only feat that this sensor is capable of.
