Patent ID: 7755691

Claim:
A driving method for a solid-state imaging device, provided with a CCD shift register as an imaging section for forming potential wells respectively corresponding to a plurality of pixels by a plurality of transfer electrodes arranged on a charge transfer channel region, and accumulating information charges generated by exposure in the potential wells, the method comprising: a shifting accumulation step in which an ON-electrode for forming the potential well in each pixel is changed within an exposure period among the plurality of transfer electrodes positioned at the pixel, and as the potential well shifts, an accumulation position to which the information charges are accumulated is shifted within the pixel; and a stationary accumulation step in which the transfer electrode used as the ON-electrode is fixed during the exposure period, wherein the shifting accumulation step is performed when the exposure period exceeds a predetermined reference value, and the stationary accumulation step is performed when the exposure period does not exceed the predetermined reference value.
