Abstract:
A solid-state image sensing device, comprising:a plurality of sensing means arrayed in the form of a matrix; a charge accumulation means that is connected to said sensing means and accumulates a charge generated at said sensing means; an accumulable charge adjusting means that adjusts the amount of accumulable charge of said charge accumulation means; and a control means that controls said accumulable charge adjusting means; wherein said control means controls said accumulable charge adjusting means to switch said amount of accumulable charge in the order of Qsat(1) and Qsat(2) within one imaging period, while controlling the accumulation modes of Qsat(1) and Qsat(2) to satisfy: Qsat(1)/t(1)Qsat(2)âˆ’Qsat(1))/(t(2)âˆ’t(1)), where Qsat(1) is a first amount of accumulable charge, Qsat(2) is a second amount of accumulable charge, a finish time of accumulation mode of Qsat(1) is t(1) and a finish time of accumulation mode of Qsat(2) corresponding to the end of one imaging period is t(2).
