Abstract
An automated system for testing imaging sensors 10 is disclosed. The automated system 10 provides an accurate and repeatable method for testing imaging sensors. The automated system 10 includes an input circuit 20 for receiving input from an imaging sensor system and providing a signal in response thereto, a processor 30 for operating on said signal and generating data therefrom, and a computer 40 for providing output in response to the data. A specific teaching of the invention includes a method for obtaining data for the lookup table and calculating addresses for the data wherein the addresses are a function of the signal and noise components of the imaging sensor system output, while the data relates to actual responses of human observers.
