Abstract
A driving method of a solid-state imaging device vertically transfers a signal charge obtained by photoelectric conversion and horizontally transfers the signal charge vertically transferred to output an imaging signal corresponding to the signal charge. For every charge packet unit for transferring the signal charge, the charge packet unit being formed of columns of transfer channels used in the vertical transfer, a backward transfer channel behind the charge packet in a vertical transfer direction is turned off substantially simultaneously with turning on of a forward transfer channel ahead of the charge packet.
Claims13
A solid-state imaging system comprising:
- a transfer unit having a backward transfer channel between a different transfer channel and a transfer channel array, said transfer channel array being between said backward transfer channel and a forward transfer channel:
- wherein said transfer channel array is in contact with said forward transfer channel and said backward transfer channel, said backward transfer channel being in contact with said different transfer channel,
- wherein {N} is the number of fields in a frame with said number of fields {N} being an integer amount of three or more, the number of transfer channels in said transfer channel array being {(N×2)−3},
- wherein, during a time period and a subsequent time period, said transfer unit is configured to prohibit formation of a charge well in said different transfer channel while preserving charge wells generated previously in said transfer channel array,
- wherein, during a transition from said time period to said subsequent time period, said transfer unit is configured to generate a charge well in said backward transfer channel and remove a charge well from within said forward transfer channel,
- wherein, said transition is one of many time period transitions, the exact number of time period transitions in each field of the frame being {(N×2)}.
