Abstract
According to the invention, a driving method for a solid-state imaging device includes: a first holding step of holding electric charges which cause smear and are obtained from incident light in a first holding unit, in a previous field period which appears temporally earlier than a predetermined field; a second holding step of holding signal charges obtained from the incident light in a second holding unit, in the predetermined field period; a first equalization step of equalizing electric charges which cause smear and are obtained from the incident light in a subsequent field period which appears later than the predetermined field and the electric charges which cause smear and are held by the first holding unit; and a first subtraction step of subtracting the electric charges which cause smear and are equalized in the first equalization step from the signal charges which are held by the second holding unit.
