ABSTRACT:
The disclosed apparatus provides for an image to be "beam-split" between (typically) two similar--but defective--imagers. While the two imagers in question are similar in all respects, the locations of their respective defective pixels are not. Respective programmable read-only-memories (PROMS) cooperate with each of the imagers and serve to memorize the locations of the defective pixels of the imagers. If the two imagers are scanned simultaneously, then, by toggling between the imagers each time a defective pixel is read in either of the imagers, a perfect video signal (regardless of whether the imagers have isolated defective pixels, or whether such defective pixels are aligned along given rows or columns of the imagers) may be provided.
