This paper evaluates the operation of self-correcting active pixel sensors presented in [6] using Signal-to-Noise Ratio. The evaluation is based on a simplified Active Pixel Sensing (APS) model. We show that in the absence of stuck faults (i.e., no errors) the performance of the system suffers from considerable degradation especially at low illumination (i.e., typical indoor scenes). We use the same model to quantify the number of defective pixels under which self correction is beneficial.
