A read-out circuit of an image sensor is provided. The read-out circuit includes: a CDS block, including: a plurality of reset capacitors storing inputted reset values of pixels; a plurality of signal capacitors storing inputted signal values of the pixels; a plurality of reset driving devices outputting the reset values stored into the reset capacitors; a plurality of signal driving devices outputting the signal values stored into the signal capacitors; and a plurality of capacitor equalization devices equalizing electric potential levels of the reset capacitors and the signal capacitors; a reset line transferring reset value output signals of the CDS block; a signal line transferring signal value output signals of the CDS block; a differential amplification unit amplifying a difference between the individual reset value output signal and the individual signal value output signal; and a line equalization device equalizing electric potential levels of the reset line and signal line.
