Samsung announced today a new 43.7MP mobile image sensor (7968×5480), the ISOCELL Slim GH1. Using what the company calls ISOCELL Plus technology, the sensor is the first to work with 0.7μm pixels. This is the smallest pixel size in the industry and continues Samsung's innovative ways in this space; the manufacturer was the first to produce a 1.0μm-pixel image sensor back in 2015. In 2017 and 2018 Samsung introduced image sensors with pixel sizes of 0.9µm and 0.8µm, respectively. With the smaller size of this image sensor, phone manufacturers will be able to continue shrinking bezel sizes and increasing the screen-to-body ratio of their phones.
The aforementioned ISOCELL Plus technology allows Samsung's new sensor to produce such small-sized pixels and still gather enough light information to, in the manufacturer's own words, "produce bright and vivid photographs. Under low light conditions, the sensor employs Tetracell technology to merge the pixels, create a 10.9MP image, and increase light sensitivity to a level found on 1.4μm-pixel image sensors. When it comes to video, the ISOCELL Slim GH1 can produce 4K video (3,840×2,160) at 60fps.
Back in May, Samsung unveiled the 64MP Samsung ISOCELL Bright GW1 sensor with a pixel size of 0.8µm. Last month, it announced a 108MP image sensor, the first made for mobile devices with a triple-digit megapixel count. That sensor also featured a pixel size of 0.8µm.
The GW1 sensor supports electronic image stabilization (EIS) and phase detection auto-focus technology. Samsung expects to be churning out the image sensor before 2019 comes to an end.
