For machine vision application, when one can calculate, on the full dynamic range of luminance, the iSNR of a front camera sensor alone, it becomes possible for carmakers and integrators to predict if the SOTIF specification will be met for the front camera sensor but once integrated in the vehicle. It will be discussed of a proposal to define the SOTIF specification of camera sensor for machine vision, of a method to digitally pass from a camera sensor alone to a camera sensor integrated in the vehicle and finally on the constraints that the OECF of HDR camera sensor must met to enable the use of iSNR criteria for automotive industry.
