Image magnifier for the visually impaired
First Claim
1. A low-vision apparatus that displays the image of an object, said apparatus comprising:
- a support including a connection for a surface on which to place the object to be viewed;
a head unit connected to said support, said head unit in use substantially above the object to be viewed;
a camera, integral or engaged with said head unit in use capturing a visual field including at least part of said object;
a display integral or engaged with said head unit and/or said support displaying at least part of said captured visual field; and
lighting integral or engaged with said head unit and/or said support for illuminating said visual field.

Abstract
A image magnifier for the vision impaired which magnifies the image of face up source material (13) placed in the visual field of the camera (15) and displays the magnified image on a display (20). One embodiment includes a static high-resolution image mode and a second live video mode. The controller (29) provides different lighting appropriate for each mode. In a further embodiment the magnifier is transportable. Each part (17, 14, 16) is hinged (18, 19) to the other parts (17, 14, 16) allowing it to be folded into a compact lightweight form to be portably carried. In a still further embodiment the magnifier includes shielding for the lighting to minimise or avoid specular reflections.
