1. An imaging device comprising:
- an image sensor that includes an imaging surface on which a plurality of pixels are two-dimensionally arranged at equal intervals and that generates image data from a subject image formed on the imaging surface; and
an optical system that images a subject on the imaging surface, the subject being in a predetermined range of a vertical view angle and in a predetermined range of a horizontal view angle, wherein;
a number of pixels used for capturing the subject image included in a unit view angle is defined as resolution,the imaging surface includes a first region including an intersection with an optical axis and a second region different from the first region,the optical system forms the subject image on the imaging surface so as to cause resolution of the first region to be higher than resolution of the second region, anda relationship between a vertical view angle and resolution is different from a relationship between a horizontal view angle and resolution in the subject image.

Abstract
An imaging device includes an image sensor and an optical system. An imaging surface of the image sensor includes a first region including an intersection with an optical axis and a second region different from the first region. The optical system forms a subject image on the imaging surface so as to cause resolution of the first region to be higher than resolution of the second region. A relationship between a vertical view angle and resolution is different from a relationship between a horizontal view angle and resolution in the subject image.
