the camera is rotatable in a tilt direction, and a rotating shaft of the camera in the tilt direction is offset from a spherical center of the cover in a direction of an apex of the cover.
4. A method of controlling a camera apparatus, the method comprising:
rotating a shade plate that partially shades light incident on a rotatable camera which is provided inside a cover having transparency the shade plate rotating to cover a portion of a periphery of a camera lens while leaving another portion of the periphery of the camera lens uncovered;
controlling rotation of the camera and a position of the shade plate; and
storing posture information including an imaging direction of the camera and positional information on the shade plate in association with each other, wherein
a direction of the camera is controlled based on the stored posture information, and the position of the shade plate is controlled based on the stored positional information.
5. A camera apparatus comprising:
a cover that has transparency;
a rotatable camera that is provided inside the cover; and
a plurality of shade plates that partially shade light incident on the camera, wherein each of the plurality of shade plates is rotatable such that the plurality of shade plates cover a portion of a periphery of a camera lens while leaving another portion of the periphery of the camera lens uncovered, wherein
the camera is disposed in a position where the light is incident on the camera from between the plurality of shade plates.
6. The camera apparatus according to claim 5 , wherein
the camera is rotatable in a tilt direction, and a rotating shaft of the camera in the tilt direction is offset from a spherical center of the cover in a direction of an apex of the cover.
7. The camera apparatus according to claim 5 , wherein
the plurality of shade plates are disposed in a vertical direction with respect to an optical axis of the camera.
8. The camera apparatus according to claim 5 , wherein
the plurality of shade plates are individually controlled.
9. The camera apparatus according to claim 5 , wherein
the plurality of shade plates have arc shapes.
10. A method of controlling a camera apparatus, having
a rotatable camera that is disposed between a plurality of shade plates that partially shade light incident on the camera, and is provided inside a cover having transparency,
the method comprising moving the plurality of shade plates such that the plurality of shade plates cover a portion of a periphery of a camera lens while leaving another portion of the periphery of the camera lens uncovered.
11. A camera apparatus comprising:
an outer dome cover that has transparency;
a camera that is provided inside the outer dome cover and is rotatable in a tilt direction;
a pan table to which the camera is attached, wherein the pan table is rotatable in a pan direction;
a shade plate that partially shades light incident on the camera; and
a shade plate elevator that is attached to the pan table and supports the shade plate to be movable in an orthogonal direction with respect to the pan table.
12. The camera apparatus according to claim 11 , further comprising
an inner dome cover that is provided to the pan table and partially covers the camera, wherein
the shade plate is attached to the inner dome cover.
13. The camera apparatus according to claim 11 , wherein
the shade plate elevator includes a guide that guides elevating of the shade plate, a gear that elevates the shade plate, and a motor that drives the gear.
14. A camera apparatus comprising:
a body to be attached to an attachment surface;
an outer dome cover that has transparency and is attached to the body;
a camera that is provided inside the outer dome cover and is rotatable in a tilt direction;
a pan table to which the camera is attached, wherein the pan table is rotatable in a pan direction;
a cylindrical shade plate that is attached to the body to be elevated and partially shades light incident on the camera; and
a shade plate elevator that is attached to the body and supports the shade plate to be movable in an orthogonal direction with respect to the pan table.
15. The camera apparatus according to claim 14 , wherein
the shade plate is disposed outside the pan table.
16. The camera apparatus according to claim 14 , wherein
the shade plate is provided along the outer dome cover.
17. The camera apparatus according to claim 14 , wherein
the shade plate is provided inside the outer dome cover.
18. The camera apparatus according to claim 14 , wherein
the shade plate elevator includes a guide protrusion provided on the body, an inclined guide groove provided in the shade plate to be movable along the guide protrusion, a gear that rotates the shade plate, and a motor that drives the gear.
19. The camera apparatus according to claim 1 , wherein the shade plate is rotatable about an axis extending in a direction perpendicular to the optical axis of the camera.
