Abstract: Systems and methods for imaging objects are provided. An imaging device includes a sensor to provide an image of an object. The sensor can have a sensor exposure time and a sensor gain and the image includes a plurality of frames, each of the plurality of frames that can depict at least a portion of the object. The imaging device includes a motion detector to determine whether there is movement of the at least a portion of the object between adjacent frames of the plurality of frames. The imaging device also includes a controller. The controller can set the sensor exposure time to a first value in response to a determination by the motion detector that there is movement of the at least a portion of the object between adjacent frames. The controller can also set the sensor exposure time to a second value in response to a determination that there is no movement of the at least a portion of the object between adjacent frames. The controller can also adjust the sensor exposure time, the sensor gain, or both to maintain a luminance value of the plurality of frames at a target luminance value.

Abstract: Disclosed is a portable magnifier camera that can be selectively positioned into a variety of configurations. At least four distinct viewing configurations are provided: a reading mode wherein the camera rests flatly upon the viewed object; a writing mode wherein the camera rests at an angle upon the viewed object; a hand-held mode wherein the user holds the camera relative to a distant object; and an inspection mode wherein the user holds the viewed object relative to the camera. These configurations enable a user to effectively view objects of differing size and at varying distances.

Abstract: Disclosed is a tablet with an improved Braille display. The Braille display employs a pin array that allows for the selective use of either six or eight pin cells. This is accomplished by turning off or on a pin pair adjacent to each cell. The spacing of the pins also allows capacitive sensors to be located adjacent to each Braille cell. These sensors are used to determine the location of the user's finger upon the display. The pin spacing further allows geometric shapes to be generated in additional to text.

Abstract: 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.

Abstract: Disclosed is a magnification device with multiple orientations. This allows a blind or low vision user to select the best orientation for the task being performed. The device includes both opened and closed orientations. It is further configurable into document reading, near object inspection, far object inspection, and self inspection modes. The camera of the device can be manipulated by the user depending upon which of these orientations is selected. Furthermore, the camera automatically adjusts itself into one of two pre-set configurations whenever the device is opened or closed.

Abstract: Disclosed is a Braille display device. The device supports an array of individual Braille cells with corresponding tactile pins. The pins can be selectively lifted by way of reeds to generate Braille characters that can be felt by the user. The Braille characters can correspond to visible characters, such as characters on a computer screen. The display is refreshable to allow for the sequential display of lines, paragraphs, or pages. In accordance with the disclosure, the Braille cells are constructed in a manner that minimizes manufacturing costs and that also permits the size of the display to be greatly reduced.

Abstract: A device that enlarges text and images to enable a low vision person to see the text and images includes a hollow structure including a top housing and a bottom housing that are connected to one another. A camera aperture is formed in the bottom housing and a transparent light guide lens is disposed in closing relation to the camera aperture so that all light entering the camera aperture must first pass through the light guide lens. A cavity formed in the light guide lens is bounded by walls that are positioned at a critical angle. Light-emitting diodes are positioned at critical locations about the periphery of the light guide lens to illuminate the object being viewed.

Abstract: A box-like illuminator includes a top wall having a flat sheet of clear material through which an illuminated image is viewed. A bottom wall of the illuminator is also formed of a flat sheet of clear material and is positioned atop the object to be illuminated. Light from an LED is directed in a first, downward direction onto a deflection wall where it is deflected into a substantially horizontal plane, substantially orthogonal to the first direction. The deflected light impinges upon a horizontally-disposed diffuser that bends the light about ninety degrees so that it travels though the diffuser a first time in a first direction and illuminates the object atop which the illuminator is positioned. The light is then reflected by the object, travels upwardly through the diffuser a second time in a direction opposite to the first direction, and is viewed by the user through the clear material.

Abstract: A magnifier for use by people with low vision includes a large LCD display upon which an enlarged image appears. Light from an LED is directed in a first direction onto a deflection wall where it is deflected into a direction substantially orthogonal to the first direction. The deflected light impinges upon a diffuser that bends it so that it illuminates an object upon which the magnifier is placed. The light is then reflected by the object, through the diffuser, and onto a mirror positioned at an angle relative to the object. The mirror directs the light onto a camera lens and the lens focuses the light onto a sensor that drives the LCD display so that the image appears on the LCD screen. The camera is slideably mounted so the user can make the image larger or smaller by sliding the camera toward or away from the mirror, respectively.

Abstract: 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.
