There is provided an imaging system configured to include an imaging lens and an imaging device such that the maximum diameter of an effective region of a point image is a size covering three or more pixels of light receiving pixels, the point image being projected onto a light receiving surface through the imaging lens from an intended position. A signal processing unit executes restoration processing on first image data output from the imaging device that images an optical image of a subject through the imaging lens, the restoration processing being executed to generate second image data equivalent to the first image data output from the imaging device when the resolving power of the imaging lens is higher. The imaging lens includes a first lens group, which includes at least one lens and has a positive power, and a second lens group, which includes at least one lens and in which a lens positioned closest to the image side has a negative power, in order from the object side.
