Abstract
According to one embodiment, a solid-state imaging device includes a VOB region, an effective pixel region, a comparator, a holder, and a drive controller. The effective pixel region outputs the reset signal, and an image signal to the vertical signal line. The comparator compares the reset signal transferred from the VOB region through the vertical signal line with a reference signal, and determining whether the reset signal is within a digital level range. The holder is capable of holding either a value representing a first result or a value representing a second result, according to a determination result of the comparator. The drive controller varies a pulse timing period according to the value held by the holder, and automatically sets the period when the reset signal is read from the effective pixel region to the vertical signal line. A voltage of the vertical signal line is clamped in the period.
