It was Here, this bright portion (2) corresponds to the signal portion read from the output portion during the period t 1 in which 30 [V] is being applied to the N-type silicon substrate portion,
The dark portion (3) corresponds to the signal portion read from the output portion during the period t 2 in which 10 [V] is applied to the N-type silicon substrate portion, and the difference in contrast in the reproduced image is Since there is a period t 1 in which the voltage of the N-type silicon substrate is high and a period t 2 in which the voltage of the N-type silicon substrate is low in one field period, it is considered that this occurs because the buffer amplifier or the like in the output section undergoes modulation such as changing the operating point.
