1. An imaging device comprising:
an imaging element;
an optical system configured to form an image on an imaging surface of the imaging element and has a characteristic in which an image formation magnification differs depending on a position in the imaging surface; and
at least one processor or circuit configured to function as
a demosaic unit configured to generate color image data of at least two colors from the data output from the imaging element,
