ENSURING IMAGING SUBSYSTEM INTEGRITY IN CAMERA BASED SAFETY SYSTEMS

摘要

In described examples, a method of testing an imaging subsystem of a system-on-a-chip (SOC) is provided that includes executing imaging subsystem test software instructions periodically on a processor of the SOC (500, 502, 504), receiving reference image data in the imaging subsystem (506) responsive to the executing of the test software instructions, performing image signal processing (508) on the reference image data by the imaging subsystem to generate processed reference image data, and using the processed reference image data by the test software instructions to verify (510) whether the imaging subsystem is operating correctly.
