Samsung's brand new ISOCELL Slim 3T2 sensor is designed for punch hole cameras

Samsung has announced its new small-sized ISOCELL Slim 3T2 image sensor. The sensor utilizes the company's ISOCELL Plus technology and features 20MP resolution that fits in a tiny 1/3.4" form factor. The company insists that's the smallest image sensor currently on the market.

The sensor fits 0.8μm pixels and comes with the Tetracell binning tech that combines four different pixels into one for better results in low-light conditions. Effectively, when there's enough light the sensor acts as a 5MP unit with big 1.6μm pixels.

The ISOCELL Slim 3T2 can also be an improvisation for the main camera for telephoto purposes in which case it uses a standard RGB color filter instead of the Tetracell array. It further reduces the sensor's height by around 7% while retaining 60% higher effective resolution at 10x digital zoom compared to a normal 13MP unit.

Still, Samsung says the ISOCELL Slim 3T2 is meant for use mostly in modern notch and punch hole camera designs due to its small size. It is expected to go into mass production this quarter and has potential to appear in future mid-range handsets.
