1. An image sensor device comprising:
an image pixel configured to
output a reset voltage through a data line during a first time period and
output a first data voltage through the data line during a second time period after the first time period; and
a voltage hold circuit connected with the data line, and configured to:
store a first voltage based on the reset voltage, and
provide a second voltage based on the first voltage to the data line during a third time period between the first time period and the second time period.
