Abstract: An integrated color imaging system has a housing with an objective lens, photocathode and image intensifier. The image intensifier has radiation sensitive sensors and a phosphor screen. A rotatable first filter wheel is located between the objective lens and the photocathode. The first filter wheel can include first channels selectively positionable in an optical path of the image, and at least one of the first channels is clear and unfiltered. A rotatable second filter wheel can be located inside the housing between the phosphor screen and an eyepiece lens of the housing. The second filter wheel can include second channels selectively positionable in the optical path between the phosphor screen and the eyepiece lens, and at least one of the second channels is clear and unfiltered. The clear and unfiltered channels of the first and second filter wheels can be selectively aligned and held in the optical path.

Abstract: The systems and methods for real time transmission of an image from an image sensor having a field of view to a processor for selectively adjusting a resolution of the image as a function of a viewer's focus point.

Abstract: Systems and methods for processing data representative of a full color image. Such systems may comprise the steps of assisting a color blind person to indicate portions of an image which to their color-deficient vision are indistinguishable, and altering the image to cause those portions to become distinguishable and identifiable.

Abstract: Systems and Methods for viewing an interior portion of an eye in a substantially dark ambient environment using an image intensifier, a color night vision device, or generally a low light sensitive imager capable of outputting an image, including color image.

Abstract: Featured are apparatus and methods for converting a monochrome night vision or other electro-optical device into one that provides a sensation of full color, including from red to blue with white and black. The method provides color images from an electro-optical device in which the image data from the electro-optical device contains brightness information of an area being viewed by the device without separate color information. Such a method includes operably coupling an optical channel system to the electro-optical device and configuring the optical channel system and arranging the optical channel system with respect to the electro-optical device so two color informational channels are provided to the viewer, whereby the two informational channels formed by said configuring and arranging of the optical channel system are such that the viewer sees a color image.

Abstract: Systems and methods for determining and addressing color-vision impairment by allowing a patient to compare multiple images of a scene wherein the color content of selected ones of the images has been manipulated by altering a portion of the color space that is less detectable to a person having a particular type of color vision impairment.

Abstract: A device for conveying enhanced, visually perceptible cues to a color-blind observer includes a first safety color that is highly visible to an observer having ordinary color vision, and a second color more perceptible by blue-sensitive photoreceptors of a retina of the observer than by other photoreceptors of the retina. As blue color-blindness is rare, the device uses a hue of blue to augment the visibility of safety-related devices such as road signs, hunting vests and other safety garments, vehicle indicator lights, etc., for an overwhelming majority of color-blind individuals who are red-green color-blind. The device employs the use of a hue of blue in a setting that is otherwise predominantly colored by a commonly-use safety hue, such as orange, red, or green.
