An imaging system includes: an optical unit an imaging device configured to capture an optical image imaged by the optical unit and a processing device configured to perform image processing on image data transmitted from the imaging device. The processing device includes: a data acquisition unit configured to acquire view angle correction data from a first storage unit and a correction unit configured to correct at least one of first image data and second image data based on the view angle correction data acquired by the data acquisition unit such that a view angle of a first image corresponding to the first image data and a view angle of a second image corresponding to the second image data match each other, and a size of the first image and a size of the second image match each other.
