Almost all Advanced Driver Assistance Systems (ADAS) today and in the foreseeable future are built primarily on machine vision to drive the decision process. With the rapid proliferation of ADAS solutions and the introduction of the ISO 26262 safety standard for passenger vehicles, functional safety considerations for those imaging systems becomes paramount. The manner in which safety measures are implemented and verified can have significant impact to the overall system design, including cost, reliability, and complexity.

This paper will examine functional safety in the imaging subsystem and its implications to system design.
