Samsung CMOS

The ISOCELL CMOS camera sensors are a family of sensors produced by Samsung and available for purchase by other companies. They are used in a wide variety of products including mobile phones, computers and digital cameras.

Design

These sensors use one of the following pixel type technologies:
*FSI: frontside-illuminated. The light that reaches the photosensitive area is reduced because it needs to pass through multiple metal and dielectric layers.
*BSI: backside-illuminated.The metal wiring shifted to backside of photosensitive area(photodiode). The light reaches the photosensitive area directly.
*ISOCELL: ISOCELL combines 3D-BSI with Front-side, Full-depth, Deep-Trench Isolation (F-DTI) and Vertical Transfer Gate (VTG). This provides increased light sensitivity and higher color fidelity even in poor lighting conditions.
*ISOCELL Plus: ISOCELL Plus replaces ISOCELL's metal grid barriers with an innovative new material developed by Fujifilm. This minimizes optical loss and light reflection, providing higher color fidelity and up to a 15% enhancement in light sensitivity compared to ISOCELL.
*ISOCELL 2.0: ISOCELL 2.0 builds on ISOCELL Plus technology by additionally replacing the lower portion of the color filter barriers with a more reflective material. It further reduces optical loss in each pixel and drastically improves light sensitivity producing even more vivid pictures with reduced noise.

These sensors can be configured with one of the following chroma technologies:

* BW also known as Monochrome. No color filter array.
* RGB also known as Bayer filter or RGGB. Features a repeating 2×2 pattern with 1 red, 2 green and 1 blue pixels.
* Tetracell also known as Quad Bayer or 4-cell. For darker scenes, signal processing can combine data from 2x2 pixel groups to essentially act like a larger pixel with a repeating 4×4 subpixel pattern with 4 red, 8 green and 4 blue subpixels. For brighter scenes, signal processing can convert the Tetracell into a conventional RGB filter to achieve 4x higher resolution. Resolution & pixel size listed below is after re-mosaic signal processing.
* Nonacell is similar to Tetracell, but with 3x3 pixel groups and a 6×6 pattern with 9 red, 18 green and 9 blue subpixels.
*ChameleonCell is similar to Tetracell and Nonacell, but with 4x4 pixel groups and a 8x8 pattern with 16 red, 32 green and 16 blue subpixels.

List of sensors
