CCD sensors allow for a relatively noise free video signal. However, a small amount of charge is lost when electrons are shifted. Thus, the electrically inefficient CCD sensor becomes a problem for higher resolutions. Some more cons include the low serial readout time -- the amount of time the shutter requires to be closed and their necessity for more voltage for operation. CMOS sensors came later in popularity though invented during a similar time period because the technology was yet to be built. by implementing Amplifiers on each pixel, the original capacity issue can be solved. In comparison to CCD sensors, CMOs sensors require less voltage and has faster image capture. However, in any manufactured device, there is always a drawback, which in this case, is higher noise and rolling shutter. Rolling shutter is especially problematic when capturing movement because it distorts the image as it is recorded.
