20Mpixel image sensor has industry's smallest form factor
Samsung Electronics' 0.8μm-pixel ISOCELL Slim 3T2 image sensor is what the company claims to be the industry’s most compact image sensor at 1/3.4 inches (approximately 5.1-millimeters diagonally).

The device delivers 20 megapixel of image resolution for both front and back cameras. In order to support smartphones with the latest display features such as the ‘hole-in display’ or ‘notch design,’ front-facing image sensors need to minimize their size while being able to capture high-quality images. The 1/3.4-inch 3T2 snuggly fits into a tiny module making more space for the display. In addition, Samsung’s Tetracell technology, which merges four pixels to work as one, lets the 3T2 take brighter and sharper pictures in low-light settings as the color filter array’s light sensitivity increases to that of a 1.6μm-pixel image sensor at 5Mp resolution.

When applied in rear-facing multi-camera settings for telephoto solutions, the 3T2 adopts an RGB color filter array instead of Tetracell technology. The small size of the image sensor also reduces the height of the tele-camera module by around seven percent when compared to Samsung’s 1/3-inch 20Mp image sensor, allowing more elegant smartphone designs according to the company.

Compared to a 13Mp sensor with the same module height, the 20Mp 3T2 retains 60-percent higher effective resolution at 10x digital zoom that presents clearer and more accurate results.
