Abstract:
1. A lens connection module, adapted for being magnetically mounted on an image capture device, the image capture device having a front face with a lens, the lens having a body protruding from the front face and a light entry opening, the lens connection module comprising: a lens connection body configured to removably couple to the image capture device, the lens connection body comprising a base unit with a joint face for facing toward the front face of the image capture device and a light entry face opposite to the joint face, wherein the base unit has a pathway wall defining a light collecting pathway corresponding to the light entry opening and extending along a light axis, wherein the body of the lens protruding from the front face of the image capture device sleeves within an end of the pathway wall of the base unit; an external lens removably coupled to another end of the pathway wall in a manner corresponding to the light axis; a first magnetic unit including at least one magnetic component arranged on the front face in a radially asymmetric manner with respect to the light axis; and a second magnetic unit configured to magnetically engage with the first magnetic unit, the second magnetic unit mounted on the lens connection body and adapted to magnetically connect the joint face to the first magnetic unit, wherein the second magnetic unit includes a magnetic component corresponding to the at least one magnetic component of the first magnetic unit and arranged on the joint face in a radially asymmetric manner with respect to the light axis.
