Abstract
An image sensor includes: a pixel including a boosting capacitor with one electrode connected to a first node to which a charge generated from a photoelectric element is transmitted, and outputting a pixel voltage based on the first node; a row driver outputting a reset-signal that resets the first node, a boosting control-signal applied to the other electrode, and a transmission-signal transmitting the charge to the first node; a read-out-circuit receiving the pixel voltage as a first-signal before the transmission-signal is output to the pixel, and receiving the pixel voltage as a second-signal after the transmission-signal is output to the pixel. A controller controlling the row driver to change the boosting control-signal from a first-level to a second-level lower than the first-level after changing the reset-signal from an enable to a disable, and controlling the read-out-circuit to receive the first-signal and the second-signal during which the boosting control-signal is at the second-level.
