Abstract

A method of operating an image sensor includes accumulating first charges through a photo diode, applying a first transfer gate signal having a first voltage level to a transfer transistor, performing, through a reset transistor, a first reset operation on a floating diffusion node connected with the reset transistor and the transfer transistor, changing the first voltage level of the first transfer gate signal to a second voltage level higher than the first voltage level, during the first reset operation, changing the second voltage level of the first transfer gate signal to a third voltage level higher than the second voltage level, and changing the third voltage level of the first transfer gate signal to the second voltage level.
