Abstract
Interactive systems using adaptive control software and hardware from known and later developed eyepieces to later developed head-wear to lenses, including implantable, temporarily insertable and contact and related film based types of lenses including thin film transparent elements for housing cameras lenses and projector and functional equivalent processing tools. Simple controls, real-time updates and instant feedback allow implicit optimization of a universal model while managing complexity.
Core Innovation
The disclosed invention provides a visual aid eyeglass device configured to be worn by a low-vision user. The device includes a frame, a camera mounted within the frame for capturing images of a scene, and a processor configured to modify the images to produce corrected images of the scene. The corrected images are presented to one or more eyes of the low-vision user by an optical system mounted within the frame.
The optical system is configured to block an external central light path so that a central visual field of the low-vision user comprises only the corrected images of the scene. The optical system simultaneously allows an external peripheral light path passing between an edge of the optical system and the frame to reach the eye, thereby preserving the low-vision user's existing peripheral vision of the scene.
The processor modifies the captured images through real-time image modification algorithms to produce the corrected images of the scene for the low-vision user. Image processing includes magnification and contrast-related adjustments, and may include color mapping. The processor can also apply a blending function that provides a smooth transition between the central visual field and the peripheral vision, including a central-to-peripheral blending characteristic.
Claims Coverage
The independent claim defines the overall architecture and the optical central/peripheral light-path partitioning, comprising camera capture, processor image modification, and an optical system that blocks the external central light path while allowing the external peripheral light path. Dependent claims refine the image-modification parameters through magnification, contrast, color mapping, and smooth central-to-peripheral blending.
Central-only corrected images via blocked external central light path
An optical system mounted within the frame blocks an external central light path so that a central visual field comprises only the corrected images of the scene.
Peripheral vision preserved via allowed external peripheral light path
The optical system simultaneously allows an external peripheral light path passing between an edge of the optical system and the frame to reach the eye to preserve the low-vision user's existing peripheral vision.
Real-time corrected image modification from captured scene images
A processor configured to modify the images captured by the frame-mounted camera to produce corrected images of the scene.
Smooth central-to-peripheral blending of corrected images
The processor modifies the corrected images to blend smoothly from the central visual field into the peripheral vision of the low-vision user.
Magnification modification of at least a portion of the images
The processor modifies an amount of magnification over at least a portion of the images.
Contrast modification of the images
The processor modifies a contrast of the images.
Color mapping of the images
The processor applies color mapping to the images.
Overall claim coverage centers on a visual aid eyeglass device in which a frame-mounted camera and processor generate corrected images, and a hybrid optical system blocks an external central light path while allowing an external peripheral light path to preserve existing peripheral vision. Dependent features further refine image modification using magnification, contrast, color mapping, and smooth central-to-peripheral blending.
Stated Advantages
Preserves the low-vision user's existing peripheral vision of the scene while the central visual field comprises only the corrected images.
