1. An imaging device using a CMOS imaging element for imaging, comprising:
a memory configured to store, as a correction reference value, a gain exceeding a gain obtained by the CMOS imaging element and at which a linear fixed pattern noise starts to occur in a captured image; and
an image processor configured to perform processing for suppressing the fixed pattern noise on the captured image when a gain when providing the gain exceeding the gain obtained by the CMOS imaging element exceeds the correction reference value,
wherein the captured image includes a plurality of pixel lines,
each pixel in each of the plurality of pixel lines is arranged according to one of a plurality of color scheme patterns, and
the image processor performs processing for suppressing the fixed pattern noise on the capture image when a pixel line of the fixed pattern noise is not continuous in the same color scheme pattern, or when the pixel lines of the fixed pattern noise are continuous in the same color scheme pattern and the number of continuous lines is two.
