Abstract
A method, system, and processor-readable medium for non-invasive visual compensation for a person suffering from central vision impairment. Digital images of a target field of view can he obtained and processed to generate processed images thereof, wherein central regions of the digital images that normally would reach an impaired portion of a retina of the person are moved to other regions of the target field of view. The processed images can be presented to the person such that the central regions are now directed at an unimpaired peripheral portion of the retina of the person.
Claims20
A method for non-invasive visual compensation for a person suffering from central vision impairment, said method comprising:
- obtaining digital images of a target field of view;
- processing said digital images to generate processed images thereof, wherein central regions of said digital images that normally would reach an impaired portion of a retina of said person are moved to other regions of said target field of view;
- and
- presenting said processed images to said person such that said central regions are now directed at an unimpaired peripheral portion of said retina of said person.
A system for non-invasive visual compensation for a person suffering from central vision impairment, said system comprising:
- at least one video camera;
- at least one video display;
- a processor that communicates with said at least one video camera and said at least one video display;
- a data bus coupled to said processor;
- and
- a computer-usable medium embodying computer program code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor and configured for:
- obtaining digital images of a target field of view utilizing said at least one video camera;
- processing said digital images to generate processed images thereof, wherein central regions of said digital images that normally would reach an impaired portion of a retina of said person are moved to other regions of said target field of view;
- and
- presenting said processed images to said person utilizing said at least one video display such that said central regions are now directed at an unimpaired peripheral portion of said retina of said person.
A processor-readable medium storing code representing instructions to cause a process for non-invasive visual compensation for a person suffering from central vision impairment, said code comprising code to:
- obtain digital images of a target field of view;
- process said digital images to generate processed images thereof, wherein central regions of said digital images that normally would reach an impaired portion of a retina of said person are moved to other regions of said target field of view;
- and
- present said processed images to said person such that said central regions are now directed at an unimpaired peripheral portion of said retina of said person.
