Abstract
A camera for a vision system of a vehicle includes a housing, an imager and a lens assembly. The imager is disposed in the housing and includes a pixelated imaging array having a plurality of photosensing elements. The imager captures image data. The lens assembly is disposed at the housing. The imager is disposed at an adjustment device in the housing. The adjustment device is operable, responsive to a control signal, to adjust a position of the imager relative to the housing and the lens assembly.
Claims20
A camera for a vision system of a vehicle, said camera comprising:
- a housing;
- an imager disposed in said housing and comprising a pixelated imaging array having a plurality of photosensing elements, said imager operable to capture image data;
- a lens assembly disposed at said housing;
- wherein said imager is disposed at an adjustment device in said housing, and wherein said adjustment device, responsive to a control signal, adjusts a position of said imager relative to said housing and said lens assembly;
- and
- wherein said adjustment device, responsive to the control signal, (i) adjusts said imager relative to said housing and said lens assembly in directions parallel to a plane of said imager, and (ii) adjusts said imager relative to said housing and said lens assembly in directions normal to the plane of said imager.
A camera for a vision system of a vehicle, said camera comprising:
- a housing;
- an imager disposed in said housing and comprising a pixelated imaging array having a plurality of photosensing elements, said imager operable to capture image data;
- a lens assembly disposed at said housing;
- wherein said imager is disposed at an adjustment device in said housing, and wherein said adjustment device is operable, responsive to a control signal, to adjust a position of said imager relative to said housing and said lens assembly;
- wherein said adjustment device comprises a microelectromechanical system (MEMS) actuator;
- and
- wherein said MEMS actuator is operable, responsive to the control signal, to (i) adjust said imager in directions parallel to a plane of said imager, (ii) adjust said imager in directions normal to the plane of said imager, and (iii) tilt said imager about an axis parallel to the plane of said imager.
A camera for a vision system of a vehicle, said camera comprising:
- a housing;
- an imager disposed in said housing and comprising a pixelated imaging array having a plurality of photosensing elements, said imager operable to capture image data;
- a lens assembly disposed at said housing;
- wherein said imager is disposed at an adjustment device in said housing;
- wherein said adjustment device comprises a base portion and a movable portion that is movable relative to said base portion responsive to a control signal;
- wherein said base portion is affixed at a main circuit board of said camera and wherein said imager is affixed at said movable portion of said adjustment device;
- wherein a flexible circuit electrically connects said imager with said main circuit board;
- wherein said flexible circuit includes a flexible portion that extends between said imager and said main circuit board to allow for movement of said movable portion relative to said base portion and to said main circuit board;
- wherein said adjustment device is operable, responsive to the control signal, to adjust a position of said imager relative to said housing and said lens assembly;
- and
- wherein said adjustment device is operable, responsive to the control signal, to (i) adjust said movable portion and said imager in directions parallel to a plane of said imager, (ii) adjust said movable portion and said imager in directions normal to the plane of said imager, and (iii) tilt said movable portion and said imager about an axis parallel to the plane of said imager.
