Abstract: Disclosed is an image sensor device which includes a pixel that outputs a first pixel signal to a first column line during a first time period and outputs a second pixel signal to the first column line during a second time period, and a clamp circuit that outputs a first clamp signal to the first column line during the first time period. During the first time period, a voltage of the first column line is determined based on the first pixel signal and the first clamp signal. The pixel operates based on a first power supply voltage, and the clamp circuit operates based on a second power supply voltage lower than the first power supply voltage.
