Abstract

Disclosed is a magnifier for use by blind or low vision users. The magnifier includes a camera, such as a CMOS image sensor, that displays enlarged images upon a screen for easy viewing. The magnifier further includes a handle that is pivotally interconnected to a housing to allow for handheld use in a variety of different configurations.

Claims

1. A magnification device for use by blind or low vision users, the device comprising:

a housing storing a camera, an image processor, and an image memory, a screen associated with the housing and adapted to display images taken by the camera, the image processor being used to selectively enlarge the displayed images and change the color combinations associated with the displayed image, the displayed images being selectively stored within the image memory for later retrieval;

a handle pivotally connected to the housing, an opening formed within the handle whereby the camera can view images through the handle;

the handle having at least three discrete orientations relative to the camera, in the first orientation, the handle is positioned to be grasped by the user and the camera is positioned to view distant objects, in the second orientation, the handle is positioned as a stand for the housing and the object to be viewed is positioned in front of the camera, in the third orientation the handle is positioned on top of the object being viewed.

2. A magnification device for use by blind or low vision users, the device comprising:

a housing storing a camera and an image processor, a screen associated with the housing and adapted to display images taken by the camera, the image processor being used to selectively enlarge the displayed images;

a handle pivotally connected to the housing, an opening formed within the handle whereby the camera can view images through the handle;

the handle having a number of discrete orientations relative to the camera, with the various orientations permitting objects to be viewed at varying distances.

3. The magnification device as described in claim 2 wherein the handle has three different orientations, in the first orientation, the handle is positioned to be grasped by the user and the camera is positioned to view distant objects, in the second orientation, the handle is positioned as a stand for the housing and the object to be viewed is positioned in front of the camera, in the third orientation the handle is positioned on top of the object being viewed.

4. The magnification device as described in claim 2 wherein the image processor can selectively change the color combinations associated with the displayed image.

5. The magnification device as described in claim 2 wherein the housing further includes an image memory for selectively storing images for later retrieval.

6. The magnification device as described in claim 2 wherein the images are displayed on an external monitor.

7. A handheld magnifier comprising:

a housing with front and back faces, the housing further including first and second ends and a midpoint therebetween, a camera positioned within the housing proximate the midpoint, a screen positioned within the front face, the screen selectively displaying objects viewed by the camera;

an image processor and an image memory positioned within the housing, the image processor being used to selectively enlarge the displayed images and change the color combinations associated with the displayed image, the displayed images being selectively stored within the image memory for later retrieval;

a handle pivotally connected to the housing, the handle having first and second ends and a midpoint therebetween, an opening formed proximate to the midpoint;

a light chamber formed within the handle;

whereby the handle can be folded into facing relation with the back face of the housing such that the camera is in registry with the handle opening.
