Abstract
An imaging device using a CMOS imaging element includes a memory that stores, as a correction reference value, a gain exceeding a gain obtained by the imaging element and at which a linear fixed pattern noise starts to occur in a captured image; and an image processor that suppresses the fixed pattern noise when the gain exceeding the gain obtained by the imaging element exceeds the correction reference value. The captured image includes multiple pixel lines, each pixel in each of the pixel lines being arranged according to one of a plurality of color scheme patterns. The image processor suppresses the fixed pattern noise 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.
