Central vision impairment compensation

摘要

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.

1. 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 for conversion of said digital images from rectangular coordinates (x0,y0) to polar coordinates (r0,θ0); processing said digital images to generate processed images thereof including polar coordinates (r1, θ1) converted back to rectangular coordinates (x1,y1) 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, thereby expanding outward a central vision region corresponding to a damaged retinal area of said retina of said person so that said central vision region is now in a peripheral vision area.
