    • A sensor device for cumulatively storing incident light in the form of electric charge is arranged to monitor the level of the cumulatively stored electric charge; to have one mode in which the storing action is allowed to continue until the electric charge level reaches a first, high given level if the electric charge level reaches a preset level within a given period of time; to have another mode in which the storing action is allowed to continue until the electric charge level reaches the preset level if the electric charge fails to reach the preset level within the given period of time; and to cause a signal obtained by the storing action to be read out after the end of the storing action with a degree of gain which is variable according to the mode in which the storing action is performed.
    • 设置用于累积存储电荷形式的入射光的传感器装置,用于监视累积电荷的电平; 具有一种模式,其中如果电荷水平在给定时间段内达到预设水平,则允许存储动作持续到电荷水平达到第一高给定水平; 如果在给定的时间段内电费不能达到预设电平,则具有允许存储动作持续到电荷电平达到预设电平的另一模式; 并且使得通过存储动作获得的信号在存储动作结束后以根据执行存储动作的模式可变的增益程度被读出。
