The proprietary stacked CMOS sensor design separates the photodiodes from the pixel transistors onto different substrate layers to improve image quality.

While a 10% improvement sounds modest at face value, it's a welcomed improvement over standard lithium-ion batteries, which have more or less had the same performance over the past few years.

We now know how Nikon is getting 8K/60p Raw video from its Z9 mirrorless camera: through a partnership with intoPIX, whose TicoRAW technology enables resource-efficient Raw image compression.

Researchers at Princeton University and the University of Washington have developed a micro camera that is about the size of a coarse grain of salt. Image quality surpasses previous micro camera designs due to the team combining metasurface technology and machine learning algorithms.

Following numerous security concerns this year, Western Digital has announced that it is ending support for prior generations of My Cloud OS, which will limit the utility of some older products.

Researchers at the University of Southampton have developed a method for storing huge amounts of data on a silica disc about the size of a traditional CD. The storage technology can store up to 10,000 times more data than a Blu-Ray disc.

To celebrate its 175th anniversary, the Associated Press (AP) has published an eight-part series discussing various key moments in its history. One such moment was the introduction of the AP Portable Picture Transmitter in 1981, a device that could scan photos and send them around the world via a telephone line.

Researchers at the University of Tokyo have observed salt crystals forming in real-time at the atomic level for the first time.

Tired of multiple devices using different charging cables? So is the European Union's European Commission. Proposed legislation will require all electronic devices to use USB-C charging ports starting in 2023.

Nikon doesn't specify what kind of products we might see this sensor inside, but due to its square format, it's more likely destined for industrial applications than consumer cameras.

Robotics company MRMC has seen demand for its remote camera pods explode in the past 12 months, including at the recent presidential inauguration in the US. We sat down (remotely, of course) with representatives from MRMC and Nikon recently to learn more about the setup.

In a move that has arguably been more than a decade in the making, Adobe has ended its support for Flash, which it first acquired when it bought Macromedia in 2005. Adobe Flash has had a tumultuous nearly 25 years of existence, but despite its problems and bugs, Flash was a staple of the internet experience for many years.
