Samsung Announces 8MP RWB ISOCELL Sensor

Business Wire, Samsung Tomorrow: Samsung’s 8MP ISOCELL RWB CMOS image sensor, the S5K4H5YB, is aimed to front-facing mobile cameras. By combining ISOCELL technology with the newly developed RWB (Red-White-Blue) color filter, the new image sensor enhances light sensitivity and color fidelity, allowing an improvement of over 3 dB in SNR in low light settings. In addition, unlike other types of color pattern configurations, the high similarity between the RWB and RGB patterns eliminates the need for an RGB convertor in a RWB filter, which prevents unnecessary color deviation.

Physical barriers between each ISOCELL pixel allow 30% decrease in crosstalk and 30% increase in full-well capacity when compared to "conventional" BSI sensors, possibly, S5K4H5YC.

Samples of the 8 MP RWB ISOCELL image sensor are available for customers and mass production of the product is scheduled for Q2 2015. Incidentaly, the S5K4H5YB has already been announced a year and a half ago. By that time, Samsung said "The S5K4H5YB is currently sampling to customers with mass production scheduled for Q4 2013." However, in the earlier announcement, Samsung has not mentioned RWB CFA.

Samsung S5K4H5YB product page says that it's already in production:


  1. Why Samsung outsourced image sensor from Sony in their flagship GS6 phone? While theirself has ISOCELL sensor fabbed in house? I don't get it. Is Sony still the best supplier?

  2. One question. Where are the available samples? I have seen a few articles say this, but there are no links within these articels and I have been searching google without any result.
