Claims23
A camera module configured to be mounted to an inside of a windshield of a vehicle and to image an external environment of the vehicle, the camera module comprising:
- a lens unit including a wide angle lens;
- and
- an imager to image the external environment by forming thereon an optical image from the external environment through the lens unit, wherein
- the wide angle lens has a wide angle optical surface on an external environment side,
- the lens unit defines an optical axis,
- an area of the wide angle optical surface above the optical axis is larger in size than that of an area of the wide angle optical surface lower than the optical axis,
- the lens unit further includes a lens barrel accommodating the wide angle lens,
- the wide angle lens further includes a locked recess portion recessed on an outer peripheral side of the wide angle optical surface, and
- the lens barrel has a locking portion locking the locked recess portion at a locking position, the locking position being located on a common plane in a circumferential direction, which is along an outer contour of the wide angle optical surface.
A camera module configured to be mounted to an inside of a windshield of a vehicle and to image an external environment of the vehicle, the camera module comprising:
- a lens unit configured by a combination of a plurality of lenses, wherein the plurality of lenses includes a wide angle lens which is disposed on an external environment side of an other lens among the plurality of lenses;
- and
- an imager to image the external environment by forming thereon an optical image from the external environment through the lens unit, wherein
- the wide angle lens has a wide angle optical surface on the external environment side,
- the wide angle optical surface on an upper side of an optical axis of the other lens is larger in size than that on a lower side of the optical axis of the other lens, the optical axis passing through a principal point of the wide angle lens,
- the lens unit further includes a lens barrel accommodating the wide angle lens,
- the wide angle lens further includes a locked recess portion recessed on an outer peripheral side of the wide angle optical surface, and
- the lens barrel has a locking portion locking the locked recess portion at a locking position, the locking position being located on a common plane in a circumferential direction, which is along an outer contour of the wide angle optical surface.
A camera module configured to be mounted to an inside of a windshield of a vehicle and to image an external environment of the vehicle, the camera module comprising:
- a lens unit configured by a combination of a plurality of lenses, wherein the plurality of lenses includes a wide angle lens which is disposed on an external environment side of an other lens among the plurality of lenses, which defines a single optical axis thereof;
- and
- an imager to image the external environment by forming thereon an optical image from the external environment through the lens unit, wherein
- the wide angle lens has a wide angle optical surface on the external environment side,
- a geometric center of the wide angle optical surface is shifted toward an upper side of the single optical axis, the optical axis passing through a principal point of the wide angle lens,
- the lens unit further includes a lens barrel accommodating the wide angle lens,
- the wide angle lens further includes a locked recess portion recessed on an outer peripheral side of the wide angle optical surface, and
- the lens barrel has a locking portion locking the locked recess portion at a locking position, the locking position being located on a common plane in a circumferential direction, which is along an outer contour of the wide angle optical surface.
