Abstract
A solid-state imaging device of the present invention includes: photodiodes having a vertical overflow drain structure; vertical shift registers for temporarily storing signals transferred from the photodiodes; and a horizontal shift register for storing and horizontally transferring signals transferred from the vertical shift registers, wherein a φSUB pulse is applied to the substrate, the φSUB pulse having a larger pulse width than a φV pulse applied to the gate electrode of each vertical shift register. Thus, it is possible to sweep out smear charges from the photodiode toward the substrate.
