Abstract
An imaging device supplies a first constant potential and a second constant potential to a photodiode through a first line and a second line to put the photodiode in a reverse-bias state. The imaging device reads a signal corresponding to the potential at the other end of the photodiode changed by light incident on the photodiode in the reverse-bias state. The imaging device supplies a potential that changes with time to a capacitive element through a control line so that a forward current flows through the photodiode disposed between the capacitive element and the first line after reading the signal.
