摘要

Digital signals (DN1, DN2, DS1, DS2) are generated on the basis of a potential at an input node of comparison means (301) by using a first reference signal (Vr1) whose potential changes by a first amount per unit time and a second reference signal (Vr2) whose potential changes by a second amount per unit time, the second amount being greater than the first amount. A correction value (±, ²) based on a difference in signal value between the digital signals (DN1, DN2, DS1, DS2) is derived. A digital signal based on a pixel signal is corrected on the basis of the derived correction value (±, ²).
