According to a WIRED report, Boston-based company Metalenz has acquired PxE Holographic Imaging, which developed the technology. It basically makes better use of incoming light by redirecting more of it toward the sensor, potentially improving low-light photography and dynamic range.
news Where smartphone cameras still struggle
Most smartphone cameras, even expensive flagships, struggle with harsh lights and dark areas in the same frame. I’ve come across this quite often while doing urban night photography, where illuminated shop signs lose details and buildings around them turn into dark patches. Trying to lift the shadows later brings up noise, despite all the software processing. Even daytime shots with high dynamic range suffer from similar issues.
PxE says its HoloCoder technology allows sensors to collect up to 2.5 times more light, potentially delivering cleaner night shots, better video capture, and improved dynamic range. Of course, the technology hasn’t been demonstrated in a commercial smartphone yet.
news How HoloCoder is trying to improve smartphone cameras
Most smartphone cameras rely on a Bayer color filter sitting above the sensor. It uses red, green, and blue filters to capture color information, but each one only allows light of its respective color to pass through, while blocking the rest. Around 60% of incoming light is lost in the process.
PxE’s solution replaces that filter with a microscopic optical layer. Instead of blocking unwanted colors, HoloCoder bends different wavelengths of light toward the appropriate pixels. The captured information is then decoded to produce an image, allowing the sensor to collect considerably more light without increasing its size.
The technology can also capture 3D depth information using the same sensor, potentially eliminating additional depth-sensing hardware. Metalenz is also eyeing applications in robotics and autonomous vehicles, although the benefits there remain uncertain. As for availability, Metalenz expects HoloCoder to reach consumer electronics by late 2027 or early 2028. No smartphone manufacturer has confirmed adopting it yet.

ARRI is redefining smartphone filmmaking with HONOR. I got an inside look at the future.
Hollywood-grade ambitions, smartphone-sized possibilities, and a partnership that’s more than just filters.
My tech-savvy teenage brother, for example, wants his phone to shoot great videos without forcing him to wrestle with LUTs, bitrates, and other technical adjustments, when all he needs is a quick clip for Instagram. Enter ARRI into the picture with HONOR, and this time around, it’s worth looking beyond the marketing gloss. This is, after all, one of the biggest names in professional cinematography, with cameras and imaging technology behind countless film and television productions. It knows a thing or two about making movies.
Telegram is turning chat messages into mini-apps because, apparently, switching apps is so last year
Telegram brings interactive widgets and TON transactions directly into chats
The move follows an announcement from Telegram founder Pavel Durov, who said any Telegram message can now be made into an app. The widgets are lightweight (the compressed code is limited to 4KB) and they use native rendering instead of opening a browser-like interface. But there is one big caveat: for the moment, production access is only available for private chats between users and bots. Widgets for groups and forwarding messages are still only available on Telegram’s test server.
