Obviously the CMOS imager doesn't have the memory on board to transfer
an entire frame to like an FIT CCD has. I suppose a region could be
added to the CMOS imager to store the pixel's charges so that an
entire frame can be transferred to the memory at once and then "read"
out over the frame period. But then that is what a CCD is, correct? So
remind me why CMOS imagers are desirable? Aren't they going backwards
from the advantages of the FIT CCD?
