Shulou(Shulou.com)11/24 Report--

CTOnews.com, December 20, Google Pixel phones have been using multi-frame HDR solutions to improve dynamic range and reduce ghosting. Kuba Wojciechowski, a grapevine source and developer, found that the 2023 Pixel will use an interlaced HDR (staggered HDR) solution, resulting in better image quality.

Wojciechowski recently reverse-compiled the Google Camera Go app and found that Pixel 8, which will be launched next year, will use an interlaced HDR solution. And he also said that the Samsung ISOCELL GN1 camera module used in the Pixel 6amp 7 series does not support interlaced HDR, which means that Pixel 8 will use Samsung's new ISOCELL GN2 module, which means the main camera will be upgraded.

What is an interlaced HDR solution?

Google's original HDR+ solution was to take a series of short exposures. Starting with Pixel 5 and Pixel 4a, Google has adopted a bracketing-style HDR+ solution. This technique takes five short exposures before pressing the shutter and makes a long exposure when the shutter button is pressed.

The original HDR scheme is compared with the bracketing-style HDR+ scheme, while the interlaced HDR is Samsung's more modern treatment of HDR photography. This technique captures three separate exposures (short, medium, and long) in succession at a very fast speed, and then combines them into the final photo. Therefore, there is no medium-length exposure option in Google's current HDR+ solution.

CTOnews.com learned that Samsung pointed out at the GN2 launch that interlaced HDR brings richer details and brighter colors than GN1's real-time HDR mode, and energy consumption can be reduced by up to 24%. Samsung also said that interlaced HDR is faster to film than traditional HDR solutions.
