摘要： Disclosed is a video processor for a magnifier camera. In particular, the disclosure relates to a video processor that eliminates the use of a frame buffer. This, in turn, reduces the latency otherwise present in the video signal. The disclosed video processor also allows selected portions of the display to be shaded. This highlights the non-shaded portions of the display while at the same time allowing the entire object to be perceived by the user.

摘要： The present disclosure relates to a vision assistive device for use by blind or low vision users. The device includes an imaging unit for viewing objects positioned beneath the device. The device further includes a forwardly facing screen for displaying an enlarged view of the imaged object to the user. The imaging unit is configured to take multiple views of the object, each with a different area of focus. This can be accomplished by digitally changing the imaging sensor's area of focus or by pivoting the sensor via a focus motor. In either event, the resulting images are combined into a single, integrated, focused, and composite image. Combining images with differing areas of focus helps eliminate any blurry regions in the composite image. The device further includes a rearwardly positioned fin that facilitates positioning the device in multiple different orientations. In a first orientation, the device is vertically positioned upon a desktop. In a second orientation, the device is reclined and placed in the user's lap with the fin positioned between the user's legs.

摘要： A portable magnifier camera with an associated display housing, base and handle. The camera can be selectively positioned into a variety of configurations, including: a first closed configuration wherein the display and base are in facing relation; a second opened configuration wherein the display is angled with respect to the base; and a third hand-held configuration wherein a handle is pivoted outwardly to permit a user to hold the camera relative to a distant object. The angle of the camera adjusts automatically in each configuration to ensure that the camera's light of slight is perpendicular to the object plane. These configurations enable a user to effectively view objects of differing size and at varying distances.

摘要： A method of dynamically establishing an auto-advance interval of a refreshable braille display. The method involves the step of establishing a default auto-advance value, during which a full line of braille characters remains displayed on the braille display prior to being replaced by the next line. The method further involves determining whether a current line of braille characters ends with a blank cell or a used cell and calculating the current auto-advance interval based on the number of used cells in the current line. The next line of braille characters is output after the current auto-advance interval has lapsed.

摘要： Disclosed is a portable magnifier camera with both storage and deployed configurations. In the storage configuration, the entire assembly can be carried via an associated handle. The camera is designed to rest on a desktop, or other planar surface, in the deployed configuration. When deployed, a housing and camera arm are positioned in a cantilevered arrangement over top of an object to be viewed. A camera housing, with an associated camera, is pivotally connected to the camera arm and is positioned over the object upon the camera being placed into a deployed configuration.

摘要： A method of selectively modifying output of a computer screen. An application hosts an electronic document having a background, alphanumerical characters, and one or more images. A modification tool performs a first modification step in which the modification tool modifies color and/or brightness of all content displayed on the computer screen. The invention identifies and analyzes images within that content to determine whether each image is a real-world image, such as a photograph. A second modification step, which is opposite to the first modification step, is applied to each real-world image, thereby reversing initial modification and returning the image to original, unmodified form. The computer screen outputs the modified electronic document having a modified background and modified text, but outputs the real-world image in its original, unmodified form.

摘要： Disclosed is a video magnifier. In particular, the disclosure relates to a desktop video magnifier that is design to be portable. The magnifier includes a high definition camera that is mounted upon a flexible arm. The camera arm swivels and pivots to allow the user to properly position the camera over the object to be viewed. The device is supported by a stand and a base. The stand includes a handle with a trough. The flexible arm is dimensioned to be received within the trough with the device in the collapsed configuration.

摘要： A screen reader application for visually impaired users suppresses unwanted content that is output by Braille or text-to-speech. The invention accesses, but does not modify, the document object model of the web page and enumerates web page elements for the end user to either hide or skip to. The end user selections are saved as rules which may be applied according to various levels of scope include web page specific, site specific or web-wide. A screen magnification application for visually impaired users automatically sets the visual focus and magnification level on a web page element according to end-user selection.

摘要： Disclosed is a magnifier that is adapted to rest upon a table. The magnifier includes an articulated camera arm that permits an associated camera to be pointed in a number of different directions. This permits the camera to focus upon, and enlarge, both distant and nearby objects. The magnifier also includes pivotal support legs. The legs have a first locked position to support the magnifier upon a table and a second position wherein the legs are locked in position adjacent the housing of the magnifier. This permits the magnifier to be readily transportable and stowable to accommodate the needs of the user.
