Chipworks reverse engineering report revealed that
Fujifilm's F550EXR BSI sensor with unusual color filter pattern and 1.4um pixel size is made by Toshiba, part number TCM5103PL. Here is the famous EXR pattern from
Fujifilm site:
|
- 1.Micro Lens
- 2.Color Filter
- 3.Photodiode
- 4.High Speed Transfer Circuit

Update: 3 years ago Fujifilm decided to transfer its CCD front-end production to Toshiba. Now it seems that the agreement has been extended to CMOS sensors as well.
While CFAs such as this are good for pixel binning, my concern is the image quality at full resolution. The bigger clusters of a color you have, the fewer pixels of the other colors you have in its neighborhood and the harder it gets to interpolate them.
