Beschreibung
Zusammenfassung:	An image sensor including: a pixel array including pixels each pixel including a photoelectric conversion element, a transmission transistor to transmit photocharges generated by the photoelectric conversion element to a floating diffusion node, and a reset transistor to reset the floating diffusion node based on a pixel power voltage; and a row driver to control the pixels, wherein the row driver includes a transmission control signal generator to provide a transmission control signal to the transmission transistor, wherein the transmission control signal generator includes: a first transistor to which a first voltage is applied; a second transistor connected to the first transistor; a third transistor to which a second voltage is applied, the second voltage being higher than the first voltage; and a fourth transistor connected to the third transistor, wherein an ON resistance of the second transistor is different from an ON resistance of the first transistor.
