Abstract
Camera apparatus for use with an automotive vehicle having a rear view mirror. The rear view mirror comprises a half-mirror, light reflected therefrom being visible to an occupant of the vehicle. A lens is disposed adjacent to the half-mirror and receives light passing through the half-mirror. An image pickup device is optically coupled to the lens and receives light passing therethrough to form an image signal corresponding to the received light.
Claims36
A camera device for use with a vehicle having a view mirror unit, said camera device comprising:
- the view mirror unit, coupled to the vehicle, and comprising a half-mirror for reflecting light to an occupant of the vehicle;
- image pick-up means, coupled to the vehicle, for receiving light transmitted through said half mirror;
- and
- an optical filter, connected to or integral with said half mirror, for filtering light passing through said half mirror.
A camera device for use with a vehicle having a view mirror unit, said camera device comprising:
- the view mirror unit, coupled to said vehicle, and comprising a half mirror for reflecting light to an occupant of the vehicle;
- image pick-up means, coupled to the vehicle, for receiving light transmitted through said half mirror;
- an optical filter, connected to or integral with said half mirror, for filtering light passing through said half mirror;
- a mirror angle changing mechanism, coupled to the view mirror unit, for rotating said half mirror;
- blur detection means, coupled to said image pick-up means, for detecting a blur of light received by said image pick-up means;
- and
- means for driving said mirror angle changing mechanism on the basis of an output from said blur detection means.
A camera device for use with a vehicle having a view mirror unit, said camera device comprising:
- optical means, coupled to said view mirror unit and having two opposing planar optical members, for deflecting an incident optical axis by moving said pair of opposing planar optical members relative to each other;
- driving means, coupled to said optical means, for relatively moving said opposing planar optical members;
- and image pick-up means, coupled to said vehicle, for receiving light transmitted through said optical means.
A view mirror device for a vehicle, comprising:
- an angularly displaceable mirror coupled to the vehicle, said mirror comprising a pair of opposing planar optical members;
- blur detection means, coupled to the vehicle, for detecting a blur in light incident on said mirror;
- driving means, coupled to the vehicle, for causing the angular displacement of said mirror on the basis of an output from said blur detection means;
- and
- means for relatively moving said planar optical members of said mirror to vary an apex angle thereof.
Camera apparatus for use with an automotive vehicle having a rear view mirror, comprising:
- said rear view mirror comprising a half-mirror, light reflected therefrom being visible to an occupant of the vehicle;
- a lens disposed adjacent said half-mirror, for receiving light passing through the half-mirror;
- and
- image pickup means, optically coupled to said lens, for receiving light passing through said lens and forming an image signal corresponding to the light received by the image pickup means.
A camera for use with a vehicle-mounted side rear view mirror comprising:
- a half-mirror mounted on a side of said vehicle for reflecting light incident thereon to an occupant in the vehicle;
- a lens mounted on the side of the vehicle adjacent the half-mirror, for receiving light passing through the half-mirror;
- and
- an image pickup means optically coupled to said lens, for forming an image signal corresponding to the received light.
