See Through Display enabling the correction of visual deficits

A display system comprising:

• A microdisplay device having
• A grayscale control system using pulse-width-modulation and
• A set of solid state light sources having at least two colors and
• A control system to drive said microdisplay and said light sources and
• A set of optical elements including at least one of free-form mirror, half-mirror, Fresnel mirror, HOE and DOE and
• A set of optics enabling see-through capability whereby a user simultaneously can see both the visual field in front of the display system and the projected image by said microdisplay and
• Image capturing sensor(s) and
• Video processing unit(s) with algorithms designed to modulate still and moving video images that is capable of, but not limited to, the treatment of genetic, physiological, and psychological conditions involving the visual field including, but not limited to, presbyopia, myopia, hyperopia, cataract, retinitis pigmentosa and color blindness and
• Said algorithm corrects the weakness of the vision of a viewer by enhancing the video images from said microdisplay with at least one of the capabilities among the brightness increase of selected color(s), the changes of focal length of the objects captured by said image sensor(s), the change of the size of the objects, the brightness of the objects, and the change in contrast changing in brightness gap between two visual areas.
