Abstract
An image sensor includes a light-electron conversion unit, a signal generation unit, and a selection unit. The light-electron conversion unit generates photo-charges from incident light. The signal generation unit accumulates photo-charges from the converter in a storage node during a detection period, and then generates a first analog signal and a second analog signal during an output period. The analog signals are generated based on an amount of photo-charges accumulated in the storage node. The selection unit generates an image signal based on one of the first analog signal and the second analog signal.
