摘要：
An image pick-up device includes a first correlated double sampling circuit configured to generate a first sampling signal by performing correlated double sampling on an active pixel signal output from an active pixel and generating a first comparison signal by comparing the first sampling signal with a reference signal, and a second correlated double sampling circuit to generate a second sampling signal by performing correlated double sampling on an OB pixel signal output from an optical black pixel and generating a second comparison signal by comparing the second sampling signal with the reference signal.
