A mount for joining a base object to an ancillary object is provided. The mount includes a top layer, a bottom layer, a key, a lock and a collar. The top layer is engaged to the ancillary object and the key extends therefrom. The bottom layer is engaged to the base object. The lock is a recess defined by the bottom layer and has a shape complimentary to that of the key such that the lock and key are mechanically and removeably engaged to one another. The collar extends from a top end to a bottom end. The top end is fixedly engaged to the top layer and the bottom end is fixedly engaged to the bottom layer. The collar is disposed about the lock and the key. The mount may be configured for electrical and mechanical communication and may include an interface for communication with a camera hot shoe.

A camera filter unit (10) includes a front ring (4) for holding a polarization filter (2) and a rear ring (5) for rotatably holding the front ring (4). The front ring (4) includes a rear annular wall portion (18) extending in a radial direction (R), a rear annular plate portion (19) extending rearward from the inner peripheral end of the rear annular wall portion (18), and an annular projection portion (20) projecting for a short distance from the rear end of the rear annular plate portion (19) toward the outer peripheral side. The rear annular wall portion (18), the rear annular plate portion (19), and the annular projection portion (20) form an annular recess (21) on the outer peripheral surface of the front ring (4). The rear ring (5) includes an annular protrusion (45) protruding to the inner peripheral side. The annular protrusion (45) is inserted into the annular recess (21) of the front ring (4).

An electronic device is provided. The electronic device includes an image sensor for capturing an image; a barrel including a lens group arranged about a first axis perpendicular to the image sensor, a first housing fixed to the barrel; a second housing disposed under the first housing and coupled to the first housing; at least one magnetic substance disposed at one side of the first housing; and at least one coil disposed at one side of the second housing. When power is supplied to the at least one coil, electromagnetic force is generated between the at least one coil and the at least one magnetic substance. And if the electromagnetic force is generated, the first housing rotates clockwise or counterclockwise, and the barrel moves along the first axis.

A camera module includes a lens assembly, a lens holder, and an image sensor assembly. The lens assembly includes a lens barrel and multiple lens elements embedded within the lens barrel. A change of temperature causes an optical focal shift that is determined according to an optical thermal shift rate associated with an optical design of the lens assembly. The lens holder has a lens holder CTE to compensate for the optical focal shift by thermo-mechanical expansion. The change of temperature causes a length expansion of the lens holder determined at least in part according to the lens holder CTE. The image sensor assembly includes an image sensor and a substrate coupled to the image sensor, the image sensor to capture light passing through the multiple lens elements and convert the captured light into image signals. The lens holder is attached to the lens barrel and the substrate using adhesives.

The present invention relates to a system, a transponder, a position detection apparatus, and a method for a photographic object detection system. The method comprises providing a position detection apparatus connectable to an image capturing apparatus; and providing a transponder having an identity. The method further comprises determining a position of the transponder relative the position detection apparatus, generating transponder data comprising the identity of the transponder, and generating a signal indicative of the position of the transponder relative an image frame of the image capturing apparatus.
