PURPOSE: A method for operating an image sensor is provided to remove a KTC noise which is generated by a turn on or off of a transmission transistor and a reset transistor. CONSTITUTION: A transmission gate(318) is turned off. The transmission gate is formed on a semiconductor substrate(410) in order to transmit electric charge which is accumulated in a photodiode(320). The photodiode is formed on the semiconductor substrate in order to accumulate electric charge by the amount of light incident. Electric charge is discharged by applying a positive voltage to the semiconductor substrate.
