  • Patent number: 10917610
    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.

  • Patent number: 10852516
    Abstract: An imaging device having an optical system including a free-form surface lens with rotationally asymmetric shape that forms an image on an imaging surface such that a resolution of a first region in front of the predetermined region is higher than a resolution of a second region at a lateral side of the predetermined region. The free-form surface lens has a shape that forms the image such that a resolution of a portion at a predetermined first distance away from a center of the first region in a vertical direction is different from a resolution of a portion at the predetermined first distance away from the center of the first region in a horizontal direction, the vertical direction being orthogonal to the horizontal direction, in the imaging element, in which the first region and the second region are aligned.
