摘要：
For reducing extremely conspicuous line noise appearing in a picked up image with a simple configuration without complicating the configuration of an apparatus, an imaging apparatus a first sampling and holding circuit for sampling and holding an electric signal from pixels in one column of the detection unit and a second sampling and holding circuit for sampling and holding and electric signal from pixels in the other column of the detection unit, and a control unit for controlling such that the first and second sampling and holding circuits perform the sampling and holding in mutually different timings.
