  • Imaging apparatus including device for removing foreign matter adhering on surface of optical member
    Patent number: 7639301
    Abstract: An imaging apparatus capable of easily removing a foreign matter adhering on an optical filter surface is disclosed. A rubber member holding an optical low pass filter seals an imaging sensor and the optical low pass filter, and a piezoelectric element vibrates an edge portion of the optical low pass filter in the direction of an optical axis, and gives the optical low pass filter a rotational force around an axis orthogonal to an imaging optical axis.

  • Camera having antifogging film
    Patent number: 6327430
    Abstract: A camera, or an underwater camera in particular, includes a photo-taking optical unit for photo-taking an object, and a viewfinder optical unit for observing the object, wherein an antifogging film is applied to an inner side of an optical member which is disposed in an optical path of at least one of the photo-taking optical unit and the viewfinder optical unit and which comes into contact with an external medium relative to the camera.
