ISOCELL

Design

• 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. The light reaches the photosensitive area directly.
• ISOCELL: ISOCELL combines 3D-BSI with Front-side, Full-depth, Deep-Trench Isolation and Vertical Transfer Gate. 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.

• 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.
