Abstract
A system and method is provided for rendering on a display of an electronic device a pre-corrected image of an original image to compensate for a visual impairment of a user of the device, such that the pre-corrected image when displayed on the display would be perceived by the user to be in better optical focus than the user would perceive a display of the original image. The method includes receiving hardware characteristics of the display, receiving at least one parameter describing the visual impairment of the user, receiving at least one parameter describing the conditions under which the display is seen by the user, calculating a pupil function, calculating a Point Spread Function (PSF), calculating a pre-corrected image corresponding to at least a portion of the original image to compensate for the visual impairment of the user, and rendering on the display the pre-corrected image.
