Abstract
A signal processing apparatus includes a level adjuster adjusting a level of an input signal, and a setter calculating an electric charge estimate value being a value obtained by estimating an electric charge amount of a charging and discharging element based on the charging and discharging element to which a predetermined electric charge is supplied and in which the electric charge is held and the electric charge supplied to the charging and discharging element and setting an adjustment coefficient of the level adjuster based on the electric charge estimate value.
