An image sensor device includes a first pixel that is located at a first row and a first column and comprising a first select transistor and is configured to output a first pixel signal through a first column line, and a second pixel that is located at a second row different from the first row and the first column and comprising a second select transistor and is configured to output a second pixel signal through a second column line. During a first time period, the first select transistor is turned on and the first pixel signal is output, and during a second time period, the second select transistor is turned on, and a first voltage is applied to the second column line through the second select transistor, the second time period including the first time period.
