Samsung has announced its tiniest camera sensor to date, the ISOCELL Slim GH1.
Designed specifically for ‘slim full-display devices,’ the pixels measure just 0.7 micrometers (?m) each for a total 43.7-megapixels (7,968 x 5,480 pixels) of resolution. As its name suggests, the ISOCELL Slim GH1 uses Samsung’s ISOCELL Plus technology, which uses pixel isolation to minimize color cross-talk, an issue that becomes more problematic the smaller pixels get.

Samsung also notes the ISOCELL Slim GH1 offers its Tetracell technology, which uses pixel-merging methods to give the sensor ‘light sensitivity equivalent to that of a 1.4?m-pixel image sensor.’
The ISOCELL Slim GH1 is capable of recording 4K video at up to 60 frames per second by using Samsung’s Tetracell technology to downsample the footage down to 3,840 x 2,160 pixels, a resolution that covers the standard resolution of 4K video (3,840 x 2,160 pixels). It also features phase detection autofocus, real-time HDR capabilities and gyro-based electronic image stabilization (EIS).

Samsung says it will start production of the ISOCELL Slim GH1 by the end of the year, meaning we probably won’t see it inside any devices until 2020. Based on the ‘Slim’ nomanclature and the mention of ‘selfie’ in the press release, it’s likely this particular sensor will be used as a front-facing camera, although it’s certainly not limited to such implementations.

Samsung Introduces Industry’s First 0.7?m-pixel Mobile Image Sensor
Samsung ISOCELL Slim GH1 offers 43.7 megapixels in an extremely compact package, ideal for slim full-display smartphones
Samsung Electronics, a world leader in advanced semiconductor technology, today introduced the industry’s first 0.7-micrometer (?m)-pixel image sensor, the 43.7-megapixel (Mp) Samsung ISOCELL Slim GH1. Thanks to advanced ISOELL Plus technology, the new ultra-high-resolution GH1 image sensor embraces 43.7-million 0.7?m-sized pixels in a super-small package, providing the optimum solution for slim full-display devices.
“Samsung has been stepping up in pixel technology innovation from the industry’s first 1.0?m-pixel image sensor, to most recently, 0.8?m ultra-high-resolution sensors at 64Mp and 108Mp,” said Yongin Park, executive vice president of the sensor business at Samsung Electronics. “We are pleased to deliver yet another breakthrough with the industry’s first 0.7?m pixel image sensor, the ISOCELL Slim GH1 that will enable sleeker and more streamlined designs as well as excellent imaging experiences in tomorrow’s smartphones.”
The ISOCELL Slim GH1 is the industry’s first mobile image sensor to adopt the smallest pixel size in the industry at 0.7?m. By utilizing ISOCELL Plus, Samsung’s latest pixel isolation technology that minimizes color cross-talk and optical loss, the tiny 0.7?m pixels are able to absorb sufficient light information to produce bright and vivid photographs. In low-light environments, the GH1 makes use of pixel-merging Tetracell technology that enables higher light sensitivity equivalent to that of a 1.4?m-pixel image sensor.
For video recording at 4K (3,840×2,160) resolutions, the ISOCELL Slim GH1, with a high resolution of 7,968×5,480, is able to take 4K videos with minimum loss in field of view (FoV), while most high-resolution image sensors crop or scale down full image resolutions that result in a reduced FoV. Using Tetracell technology, the GH1 is converted down to 3,984×2,740, a resolution that snugly covers the 4K (3,840×2,160) resolution, allowing users to capture more detailed backgrounds when recording high-resolution videos or selfies at 60T frames per second (fps).
For sharper photographs and video, the GH1 supports a gyro-based electronic image stabilization (EIS) and a high-performing phase detection auto-focus technology, Super PD, allowing fast and accurate autofocus. In addition, the real-time high dynamic range (HDR) feature delivers more balanced exposure and richer color even in mixed-light environments.
The Samsung ISOCELL Slim GH1 is expected to be in mass production by the end of this year.
