Abstract: PROBLEM TO BE SOLVED: To suppress the generation of noises and to improve the performance of high sensitivity through exposure for a long time. SOLUTION: The signal charge reading pulses, the drive pulses and the reset pulses which are generated by a pulse generation circuit 6 are selectively transmitted by the gate circuits 8, 9 and 10 under the control of a pulse control circuit 7. The drivers 11, 12 and 13 supply the signal charge reading pulses to start the reading of the signal charge, supply the drive pulses to horizontally and vertically scan the signal charge and supply the reset pulses to reset the detection of the signal charge respectively. The supply of pulses are stopped in the period excluding the time when the signal charge is read out in an exposure period, so that the drive is stopped for the horizontal and vertical registers and also for detection of the electric charge. Thus it is possible to suppress the excessive heat generation due to the useless drive of the registers and a charge detector 3.  Then the dark current is reduced and the S/N is improved.
