Abstract
Disclosed is an image sensor including a first tap pixel, a second tap pixel, and an overflow detection circuit suitable for detecting overflow of the first tap pixel based on a first tap pixel signal outputted from the first tap pixel and overflow of the second tap pixel based on a second tap pixel signal outputted from the second tap pixel, and forming a current path from an overflow current source to a ground voltage terminal when a voltage of the first tap pixel signal or a voltage of the second tap pixel signal drops below a predetermined voltage.
