IMAGING DEVICE, DISPLAY SYSTEM, AND IMAGING SYSTEM

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.
