Samsung has officially launched a new mobile camera sensor named ISOCELL Slim GH1. It is the world's first mobile camera sensor with 0.7μm pixel size. This makes it the tiniest the pixel size available on any smartphone camera as it dethrones Samsung's 64-megapixel and 48-megapixel ISOCELL cameras launched with 0.8μm pixel size.
The new Samsung ISOCELL Slim GH1 is a 43.7-megapixel camera sensor with a peak resolution of 7,968 x 5,480 pixels. It is specifically aimed at sleeker and full-screen smartphones that are becoming the norm nowadays. The smaller size will allow OEMs to offer high-resolution selfie camera without worrying about the space.
But since it is such a small camera sensor, it will definitely raise questions about the image quality because of the lower light sensitivity, especially in low-light conditions. Samsung says its ISOCELL Plus pixel isolation technology "minimizes color cross-talk and optical loss" and will ensure that the pixels absorb sufficient light for clicking "bright and vivid photographs". It will make use of pixel merging Tetracell technology for low-light shots which we have seen getting used in 64MP and 48MP sensors as well. This will help the camera to gain a light sensitivity equivalent of a 1.4μm pixel image sensor.
This new camera sensor is capable of shooting 4K videos and also supports gyro-based electronic image stabilization (EIS). It will also offer phase detection autofocus and real-time high dynamic range. Samsung will start mass-producing ISOCELL Slim GH1 by the end of 2019. It means we should see smartphones featuring the new camera during early 2020.
