Abstract
A TV camera comprises a pair of CCD imagers subject to defects. Defect detection is done by comparing signals from the imagers, thus saving the expense of a defect location memory and also detecting more kinds of defects than one would detect by just comparing one signal to a fixed reference. As a result, CCD imagers with defects can be used thus increasing production yield of such imagers.
