摘要： An objective of the present invention is to provide the solid-state imaging device and the driving method thereof which can control: a poor picture quality, such as blooming, to maximize a dynamic range of the photodiode; and a poor picture quality resulted from an incomplete read-out operation. A solid-state imaging device in the present invention includes: a solid-state imaging element; and a driving pulse controlling unit applying a driving pulse to each of read-out gates of a column CCD. The driving pulse controlling unit transfers in a column direction signal charge within a charge transfer region of the column CCD by applying a column transfer clock having a LOW level voltage and a MIDDLE level voltage, and the LOW level voltage and the MIDDLE level voltage are minus voltages.
