摘要： A dome camera (1) includes a camera lens (4) capable of rotating in a tilt direction, and a dome cover (3) for covering the camera lens (4). A tilt rotation axis (P2) of the camera lens (4) is positioned more in a zenith direction than a center (P1) of the dome cover (3), and a polarizing filter (6) or a partially darkening filter (12) is inserted on an optical axis of the camera lens (4) as a tilt angle of the camera lens (4) becomes larger than a predetermined threshold angle. According to this dome camera (1), both securing of a wide field of view and reduction in the image quality deterioration may be achieved when capturing an image in a direction at a large tilt angle (a direction near the horizontal direction) .
