Certain embodiments of the invention include a modular video camera system that can be adapted to mount to a number of different surfaces and perform a number of different functions. Some embodiments include a video camera housing having a front portion with a camera lens and infra-red (IR) emitter disposed thereon, a mounting apparatus to couple to and secure the camera system to a window pane such that the front portion of the housing faces the window pane, and a silicone-based compound, placed between the IR emitter and the window pane, that is translucent to IR light and prevents IR light from reflecting off of the window pane and into the camera lens. Some embodiments include a video camera system with a battery pack coupled to a base support having an orientation adjustment apparatus to prevent inadvertent adjustments to an orientation of the video camera system.

The present invention is directed to a lens diaphragm device that can avoid a degradation of an image due to both diffraction of a light beam and flares. The diaphragm device includes two diaphragm vanes (2 and 4) that respectively have notches (28 and 36) opposed to each other in a single plane perpendicular to an optical axis (O), and two of the vanes are moved close to and apart from each other in the single plane so as to vary an aperture of the lens diaphragm. The lens diaphragm device also includes two optical filters (6 and 8) used to reduce a quantity of a beam of light passing through the diaphragm, and an aperture of the diaphragm defined by edges of the optical filters and the notches of the vanes is shaped to be asymmetrical about straight line which crosses the optical axis and is perpendicular to directions of the motion of the vanes.

A first lens group (G1) fixed with respect to the image plane includes a lens (11) having a negative refractive power, a lens (12) having a positive refractive power and a lens (13) having a positive refractive power. A second lens group (G2) has a negative refractive power as a whole, and causes a zooming action when moved along the optical axis. An aperture stop is fixed with respect to the image plane. A third lens group (G3) includes a lens (31) having a negative refractive power and a lens (32) having a positive refractive power, has a positive or negative refractive power as a whole, and is fixed with respect to the direction of the optical axis when zooming and when focusing. A fourth lens group (G4) has a positive refractive power as a whole, and moves along the optical axis such that the image plane, which is displaced by a movement of the second lens group (G2) along the optical axis and by a movement of the object, is maintained at a constant position with respect to a reference plane. Thus, it is possible to realize a compact and high-image quality small zoom lens that is suitable for three-CCDs.

The invention relates to an auditory canal cleaning tool and an auditory canal observing tool. An image capturing tube 220 adapted to be inserted into one's auditory canal to output an image of an interior of the auditory canal, a suction tube 230 provided along the image capturing tube 220 to suck a foreign matter in the interior of the auditory canal, and a main body unit 200 provided with the image capturing tube 220 and the suction tube 230 are included. The image capturing tube 220 includes a camera 240 adapted to capture the image of the interior of the auditory canal, and to a tip end of the suction tube 230, a dust collecting tube 232 is attached.

Provided is a video camera module capable of easily and precisely positioning a shielding housing upon a sensor substrate in a shake-proof manner. The video camera module (100) comprises: a driver body (10) that supports a lens assembly in a manner capable of moving in the direction along the optical axis (O) of a lens, a sensor substrate (40) carrying a shooting element, a substrate member (50) arranged between the driver body and the sensor substrate, and a shielding housing (60) covering the upper surface (40a) of the driver body, the substrate member, and the sensor substrate for shielding the electromagnetic noises generated from the sensor substrate. In the structure, the upper end (60a) of the shielding housing (60) extends to the upper surface (40a) of the sensor substrate (40). The substrate member (50) comprises at least two protruding parts (542) protruding toward the outboard in the radius direction. The shielding housing (60) is jogged with the two protruding parts in a light-pressing manner.

The invention relates to a retaining device for a still or video camera in the interior of a motor vehicle with a fastening apparatus (5, 5a, 5b, 5c, 5d, 5e) for attaching the retaining device to a vehicle seat part, such as a backrest (2), headrest (3) or headrest holder (4, 4a, 4b) of a vehicle seat (1), and a carrier arm (6, 6', 6'', 60, 60', 60'', 62, 62', 62'') which is oriented approximately horizontally and parallel with respect to the broad side of the backrest (2) and at one end of which a holder (7) is arranged for receiving a camera (8), wherein the carrier arm (6, 6', 6'', 60, 60', 60'', 62, 62', 62'') protrudes beyond the vehicle seat part (2, 3, 4, 4a, 4b) to such an extent that the lens (8a) of the camera (8) has an uninterrupted view towards the front in the driving direction and / or towards the rear in the direction counter to the driving direction, and wherein, at the other end thereof, the carrier arm (6, 6', 6'', 60, 60', 60'', 62, 62', 62'') is connected via a first rotary joint (6a) with an approximately vertically oriented rotational axis Z2 to the fastening device (5, 5a, 5b, 5c, 5d, 5e) and can be pivoted in an approximately horizontal plane.
