Abstract
An imaging device includes an optical element including a transparent substrate and a plurality of structures disposed on or in the transparent substrate in a plane direction of the transparent substrate, an imaging sensor in which a plurality of pixels each including a photoelectric conversion element are arranged, and a signal processing unit configured to generate an image signal based on an electric signal obtained from the imaging sensor, wherein the optical element outputs light with a different point spread function for each wavelength to form, on the imaging sensor, an image in which the point spread function of each wavelength is convoluted, the plurality of structures have the same height in a side view, and the signal processing unit reconstructs an image in which the point spread function of each wavelength is convoluted.
