Abstract
In a solid-state image-sensing device, first a switch Swa is turned on to sample and hold an image signal in a capacitor Ca, and then the switch Swa is turned off. Next, a switch SWb is turned on to sample and hold a noise signal in a capacitor Cb, and then the switch SWb is turned off. Next, switches SWand SWare turned on simultaneously so that the image signal in the capacitor Ca is fed through a bufferto a capacitor Cc, and then the switches Swand Sware turned off. Then, a switch SWis turned on to reset the input side of the bufferNext, switches SWand SWare turned on simultaneously so that the noise signal in the capacitor Cb is fed through the buffer to a capacitor Cd, and then the switches SWand SWare turned off. Then, the switch SWis turned on to reset the input side of the bufferagain.
