View Patent ↗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.
1. A magnification device for use by blind or low vision users, the device comprising:
a housing having a rear face with a camera and a front face with a screen adapted to display images taken by the camera, the housing storing an image processor and an image memory, 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;
a battery positioned within 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, with the battery within the handle functioning as a counterweight, in the third orientation the housing and handle are brought into facing relation, the handle is positioned on top of the object being viewed and the object is displayed on the screen.
2. A magnification device for use by blind or low vision users, the device comprising:
a housing having a rear face with a camera and a front face with a screen adapted to display images taken by the camera, the housing storing a camera and an image processor, 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;
a battery positioned within the handle;
the handle having at least two discrete orientations relative to the camera, in one orientation, the handle and battery together function as a stand for the housing and the object to be viewed is positioned in front of the camera, in another orientation the housing and handle are brought into facing relation, with the object being viewed displayed on the screen.
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.
