PROBLEM TO BE SOLVED: To properly perform shading correction.SOLUTION: An imaging device comprises: a photoelectric conversion part; and a correction part for correcting the angle of light incident to the photoelectric conversion part, the correction part being provided on a side where the light is incident to the photoelectric conversion part. The correction part has a curve surface being a spherical surface. The shape of the surface is based on a predetermined expression expressed by the radius of the spherical surface, a distance from the center of the light axis of an image surface to the end of the image surface, a refraction factor of material constituting the correction part, and a maximum incident angle of light. This technique can be applied to the imaging device. |
