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: 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.

Abstract: A vehicle-mounted stereo camera device that achieves high-precision distance detection is provided. The provided vehicle-mounted stereo camera device includes a left camera and right camera disposed on a vehicle via a holder to cause visual fields to overlap each other, a stereo processor that calculates a distance to a body outside the vehicle based on images captured by the left camera and right camera and on positions on the vehicle, first and second geomagnetic sensors respectively disposed near the left camera and right camera, and a third geomagnetic sensor disposed on the holder. The stereo processor compares a geomagnetic value detected by the first or second geomagnetic sensor with a geomagnetic value detected by the third geomagnetic sensor, detects a displacement amount of the left camera or right camera, and changes a cutout position in the image captured by the left camera or right camera based on the displacement amount.
