    • Defective sweep occurs when strong light enters, i.e., a quantity of input light increases, and smear and blooming components increase during an exposure period because a quantity of unnecessary charge to be swept during a sweep-out transfer period of a first field side exceeds a quantity of charge to be handled. The inventive image pickup system solves the above-mentioned problem by setting the sweep-out transfer period of the first field side to be longer than the sweep-out transfer period of a second field in a digital still camera which controls an exposure time by using a mechanical shutter in using as an image pickup device, a solid-state image pickup device which carries out the sweep-out transfer of transferring and sweeping charges within a vertical transfer section quickly more than transfer speed in transferring the signal charges read out from a sensor section to the vertical transfer section before reading out the signal charges from the sensor section to the vertical transfer section.
    • 当强光进入时,即,一定量的输入光增加,并且在曝光期间污迹和起霜分量增加,因为在第一场侧的扫除传送期间扫描的不必要的电荷量超过了 要处理的费用数量。 本发明的图像拾取系统通过将第一场侧的扫除传送周期设置为比通过使用控制曝光时间的数字静态照相机中的第二场的扫出传送周期长的方式来解决上述问题 使用作为图像拾取装置的机械快门,固态图像拾取装置,其在垂直传送部分内快速地执行传送和扫描电荷的扫除传输,而不需要传送从传输速度传送从 传感器部分到垂直传送部分,然后从传感器部分向垂直传送部分读出信号电荷。
