Then, by using the 2nd charge pulse provided in the vicinity of immediately after the start of the vertical scanning period, signal charges accumulated in the conversion section 11 during the vertical scanning period after the 1st charge pulse are transferred to the vertical transferring section 12. Thereafter, during the vertical scanning period until the next charge pulse, the signal charges of one horizontal line quantity are successively transferred from the transfer section 12 to a horizontal transfer section 13 by means of vertical transfer pulses at very one horizontal period. Then the signal charges are outputted from the transfer section 13 through a detecting section 14 by means of horizontal transfer pulses.
