CCD integration
Switched output integration
A PAL television picture is composed of 625 interlaced lines. In a tube camera, the odd lines are scanned first then the beam returns to the top of the frame to scan the even lines. It requires two of these fields to produce a complete picture (frame) and to synchronize with the mains frequency of 50 Hz, the picture or frame is repeated 25 times a second.
CCD frame transfer (FT) devices use the same pixels for both odd and even fields whereas interline transfer (IT) and frame interline transfer (FIT) CCDs use separate pixels with a consequent increase in resolution. There are two methods to read out the stored charge:
Field integration: This reads out every pixel but the signals from adjacent lines ...
