Google's now independent X research division, which calls itself 'the moonshot factory,' has been publishing a collection of stories about the group's graduated projects and where they stand today. The latest article in the so-called Graduate Series offers a closer look at Gcam, the software behind the class-leading cameras in Google's Pixel devices

The blog post outlines how the Gcam team was set up back in 2011 to find a solution for the Google Glasses smart goggles' most pressing challenge: providing a high-quality camera in a very small device. As using bigger hardware wasn't an option, the Gcam team developed a method called image fusion, which uses multi-frame-stacking techniques to create a single, higher quality image with lower noise levels, better detail and increased dynamic range. 

The technology, which is now called HDR+, quickly grew beyond Google Glass and made it into the Nexus 5 and Nexus 6 cameras and eventually became the default camera mode in the Google Pixel series. The Gcam team now works across a range of imaging-related technologies, including Android, YouTube, Google Photos 360˚Virtual Reality projects.
