Abstract:
A pixel signal transfer device includes a transfer block suitable for transferring a pixel output voltage according to an amount of a charge generated from a pixel; a correction block suitable for correcting the pixel output voltage using a threshold voltage of an amplification transistor; and a conversion gain adjusting block including the amplification transistor, the conversion gain adjusting block being suitable for adjusting a conversion gain of the corrected pixel output voltage outputted from the correction block.
