A dome-type camera includes a camera lens capable of rotating in a tilt direction, a dome cover for covering the camera lens, and an aperture control unit for controlling the amount of aperture of the camera lens. The amount of aperture is set to become smaller from an open value toward a closed value in accordance with the tilt angle of the camera lens becoming smaller from a zenith direction of the dome cover toward a horizontal direction. According to this dome-type camera, a desirable low tilt angle image with a reduced blur may be obtained even with a megapixel dome camera.
