Recently, non-RGB image sensors gain a traction in the automotive applications. One traction is from the demand to achieve smaller pixel size with keeping low light SNR. We did a pros/cons study of the popular color filter arrays such as RCCB, RYYCy, RCCG and RGB, including the analysis of so-called Yellow / Red traffic signal differentiation issue. The other traction is from the demand to use one camera for both of Machine Vision and Human Vision purposes, especially in Driver Monitoring Systems. RGB-Ir is under study for this application.

In this presentation, we will present those color filter options and discuss what is useful for what applications.
