One can do real-time HDR videos
Catching up with Sony’s high-resolution sensor, Samsung introduces two new sensors under the ISOCELL Bright line with the 48-megapixel GM1 and 32-megapixel GD1. Sporting 0.8um pixels, both sensors come with Tetracell tech, which combines four pixels into one pixel to increase light sensitivity to 1.6um pixels. With Tetracell, the GM1 and GD1 can output 12-megapixel and 8-megapixel photos in low light situations. Both have gyro-based EIS for stable photo and video capture.
Aside from their pixel-binning tech, the GD1 is capable of real-time HDR video recording, improving exposure, color, and detail even while shooting in low light, high contrast environments.
According to Samsung’s press release, both sensors are expected to be in mass production by the end of the year, fueling speculation that they might be used for the upcoming Galaxy S10 and Galaxy A8s.
