ABSTRACT:
This invention discloses a high efficiency solid state imager combining a semiconductor substrate having a charge transfer function and a photoelectric conversion film, wherein a high frequency transfer pulse having a frequency higher than that of a vertical transfer pulse is applied for a prescribed time during the vertical blanking period; voltages with different values are applied to a transparent electrode provided on the above-mentioned photoelectric conversion film in the first and second period of the period with the presence of the above-mentioned high frequency transfer pulse; and a voltage differing with each field is applied to the above-mentioned transparent electrode during the vertical blanking period, whereby blooming, highlight lag and flicker due to an intense light are considerably suppressed.
