PROBLEM TO BE SOLVED: To provide an imaging apparatus that reduces a noise from an image signal outputted from an imaging element while exhibiting a function of a mechanism configuring a noise source.SOLUTION: A memory 124 preliminarily stores a noise corresponding to a duty ratio of an SR (Shake Reduction) drive signal and a lens drive signal in association with the duty ratio. A noise is generated by imaging while completely shielding a CMOS 121 from light while an SR block 122 or a lens drive motor 132 are driven. BY imaging while completely shielding a CMOS 121 from light, only a noise generated from the SR block 122 or the lens drive motor 132 is included in an image signal. An image processor 114 completely receives an image signal from the CMOS 121, then the image processor 114 obtains a duty ratio for each horizontal line, and reads out a noise corresponding to the obtained duty ratio from the memory 124. A noise is subtracted for each horizontal line. |
