  • Patent number: 5517244
    Abstract: A 3-phase charge-coupled imaging device is operated in the interlace mode. During integration, voltages are applied to the clock electrodes such that charge is integrated below the same set of electrodes each time. The signal charges of the first field are formed in that 3/4 portion of the charge in each picture element is augmented by 1/4 portion of the charge of the preceding picture element, while the signal charges of the second field are formed in that the 3/4 portion is augmented by 1/4 portion of the charge generated in the following picture element. These summations may be carried out in the sensor itself in that the charge packages are shifted to the left and right during integration. The flicker which is usually the result of interlacing is very strongly reduced in this way.
