Abstract

Disclosed is a magnification device for use by blind and/or low vision individuals. The device includes an X-Y table upon which an item to be magnified can be placed. A stationary camera arm and a pivotal monitor arm are oriented over the X-Y table. The monitor arm includes a video monitor pivotally mounted at its distal end. The camera arm also includes two laterally disposed lighting arms. A series of controls are provided along a lower edge of the monitor via a mounting bracket.

First claim

What is claimed is:

1. A magnification device with a lighting arrangement that increases field of view and decreases wash-out, the magnification device comprising:
a table with a planar surface supporting an object to be magnified;
a curved camera arm having a distal end, a proximal end, and an intermediate extent therebetween, a camera supported along the camera arm for viewing and magnifying the object, the camera arm defined by a central axis and being fixed relative to the table, whereby the camera is maintained at a pre-defined distance above the object;
a cantilevered monitor arm having a distal end, a proximal end, and an intermediate extent therebetween, a panel display pivotally secured to the distal end of the monitor arm, a hinge assembly rotatably interconnecting the proximal end of the monitor arm to the intermediate extent the camera arm, the hinge assembly permitting the monitor arm to move to either side of the central axis to assist in viewing the object upon the display;
a control panel detachably secured to the display, the control panel including controls for varying the degree of camera magnification;
a lighting arm secured along the length of the camera arm at a position proximal to the hinge assembly, the lighting arm including opposing ends, each of the opposing ends extending laterally of the central axis;
a light emitting diode (LED) positioned at each of the opposing ends of the lighting arm, the light emanating from the LEDs being angled with respect to the planar surface, wherein the angle between the emanating light and the planar surface is 45.5°.

2. A magnification device that increases field of view and decreases wash-out comprising:
a table with a planar surface supporting an object to be magnified;
a camera arm having a distal end, a proximal end, and an intermediate extent therebetween, having a camera supported along the camera arm for viewing and magnifying the object;
a monitor arm having a panel display pivotally secured to a distal end, the monitor arm being rotatably connected to an intermediate extent the camera arm, the connection permitting the monitor arm to move to either side of camera arm to assist in viewing the object upon the display;
a control panel secured to the display, the control panel including controls for varying the degree of camera magnification;
a lighting arm secured along the length of the camera arm at a position proximal to a hinge assembly interconnecting the camera arm and the monitor arm, the lighting arm including opposing ends, each of the opposing ends extending laterally of the camera arm;
a light source positioned at each of the opposing ends of the lighting arm, the light emanating from the light sources being angled with respect to the planar surface.

3. The magnification device as described in claim 2 wherein the angle between the emanating light and the planar surface is 45.5°.

4. The magnification device as described in claim 2 wherein the angle between the emanating light and the planar surface is less than 90°.

5. The magnification device as described in claim 2 wherein the camera arm is defined by a central axis and wherein the monitor arm can be positioned on either side of the central axis.

6. The magnification device as described in claim 2 wherein the camera arm is fixed relative to the table, whereby the camera is maintained at a pre-defined distance above the object.

7. The magnification device as described in claim 2 wherein the lighting arm is angled with respect to the planar surface.

8. The magnification device as described in claim 2 wherein the monitor arm can be vertically adjusted relative to the camera arm.

9. A magnification device comprising:
a table with a planar surface supporting an object to be magnified;
a camera arm having a distal end, a proximal end, and an intermediate extent therebetween, having a camera supported along the camera arm for viewing and magnifying the object;
a monitor arm having a panel display pivotally secured to a distal end, the monitor arm being connected to an intermediate extent the camera arm via a hinge, the hinge permitting the side to side and vertical movement of the monitor arm relative to the camera arm;
a control panel detachably secured to the display, the control panel including controls for varying the degree of camera magnification; and
a lighting arm secured along the length of the camera arm, the lighting arm including opposing ends, each of the opposing ends extending laterally of the camera arm and supporting a light source, the light sources indirectly lighting the object to be magnified.
