Google Pixel 8 to feature Samsung ISOCELL GN2 camera

Understanding Google’s Upcoming Pixel 8 Camera Upgrade with Interleaved HDR Solution

Recently, Wojciechowski reverse-engineered the Google Camera Go application and discovered that the upcoming Pixel 8, set to be released next year, will feature an interleaved HDR solution. He also mentioned that the Samsung ISOCELL GN1 camera module used in the Pixel 6/7 series does not support interleaved HDR. This implies that the Pixel 8 will incorporate Samsung’s new ISOCELL GN2 camera module, indicating an upgrade in the primary camera setup.

What is the Interleaved HDR Solution?

Initially, Google’s HDR+ solution involved a series of short exposures. Starting from the Pixel 5 and Pixel 4a, Google has adopted a bracketing-style HDR+ approach. This technique involves capturing five brief exposures before pressing the shutter and combining them with a longer exposure when the shutter button is pressed.

On the other hand, interleaved HDR represents Samsung’s more modernized approach to HDR photography. This technology captures three separate exposures (short, medium, long) at a very fast pace and then merges them into the final image. Thus, Google’s current HDR+ solution does not feature an option for medium-length exposures.

According to IT Home, Samsung highlighted during the GN2 launch that interleaved HDR offers richer details and more vivid colors compared to the real-time HDR mode of GN1, with up to 24% lower energy consumption. Samsung also mentioned that interleaved HDR delivers faster post-processing compared to traditional HDR solutions.
