Abstract
Methods and apparatuses for non-optical testing of imaging devices having an array of pixels are provided. One or more pixels are tested by setting the photoconversion device and/or a floating diffusion region to a known voltage level that is different from that used to operate the pixel during non-test operation. The pixel is then sampled and compared to an expected value.
