Abstract: An object of the present disclosure is to increase resolution of a part required for sensing while achieving a wide view angle. An imaging device according to the present disclosure includes an image sensor and an optical system. An imaging surface of the image sensor includes a first region 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 an image in the first region to be higher than resolution of an image in the second region. The first region is arranged so as to include a region where an image of a person's face is formed on the imaging surface.

Abstract: A head-mounted display device includes a first display portion disposed in front of a pupil of a viewer and displaying a first image, a second display portion disposed on an ear side of the viewer and diagonally in front of the pupil and displaying a second image, a first lens disposed between the pupil and the first display portion for projecting a first image onto the pupil, and a second lens disposed between the pupil and the second display portion for projecting a second image onto the pupil. The second lens is disposed adjacent to the first lens on the ear side of the viewer, and an optical axis of the first lens and an optical axis of the second lens intersect with each other at an angle ranging from 30 degrees to 80 degrees inclusive.

Abstract: An imaging apparatus is attached to a side of a moving body (for example, vehicle). The imaging apparatus includes an image sensor and an optical system that forms a subject image in a range of a predetermined vertical view angle and a predetermined horizontal view angle on an imaging surface. The optical system forms an image on the imaging surface so as to cause resolution in first region (R1) of the imaging surface to be higher than resolution in second region (R2) different from the first region. A position of center (G1) of first region (R1) is at least one of a position horizontally shifted from a center of the horizontal view angle and a position vertically shifted from a center of the vertical view angle.

Abstract: Imaging system (70) disposed at a rear part of moving body (100) includes imaging device (10) and image processing device (20). Imaging device (10) includes an imaging element and an optical system. The imaging element has a plurality of pixels arranged in a two-dimensional manner and generates image data. The optical system forms a subject image on an imaging surface of the imaging element. Image processing device (20) generates a captured image based on the image data. The imaging surface includes a first region corresponding to a first view angle and a second region corresponding to a second view angle that is larger than the first view angle. The optical system is configured so that resolution of the first region is higher than resolution of the second region excluding the first region. A center of the first region is disposed at a position deviated from a center of the imaging surface.

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.
