Embodiments of a vision aid video magnification system for low-vision persons are shown and described. The system includes a balanced arm with a first portion that swivels on a base, a second portion connected to the enclosed camera, and an elbow between the first and second portions. The elbow includes a sliding spring fulcrum which enhances the smooth movement of the second arm portion and camera. The first arm portion includes an inner spring between arm tubes that helps eliminate the dead area that may be otherwise present in balanced arms. Other improvements include a flexible camera mount that preferably swivels relative to the arm, and a mirror attachment for personal care and other use. The vision aid video magnification system allows enhanced, smooth movement and versatility.

[ I claim:] [1.] A vision aid system comprising an articulated arm, a camera, and a camera mount assembly connecting said camera to the articulated arm, the articulated arm comprising:a proximal arm assembly having a first end and second end, said first end for connection to a surface;a distal arm assembly having a first end and a second end;an elbow mounting bracket pivotally connecting said first end of the distal arm assembly to said second end of the proximal arm assembly, the elbow mounting bracket having an elongated distal surface having an inner end and an outer end, wherein the inner end is nearer the distal arm assembly than is the outer end;wherein the articulated arm bends at the elbow mounting bracket to swing the distal arm assembly to a first position close beside the proximal arm assembly and to swing the distal arm assembly to a second position extending outward from and generally parallel to the proximal arm assembly; anda support spring having a distal end attached to the distal arm assembly and having a proximal end attached to the elbow mounting bracket;wherein said support spring proximal end is slidably attached to the elbow mounting bracket elongated distal surface and slides along the elongated distal surface from said inner end to the outer end when the distal arm assembly moves from said first position to said second position, whereby sliding of the support spring proximal end along the elongated distal surface allows the distal arm assembly to move smoothly and easily into substantially any position between said first position and said second position with little arm backlash.
