Claim 28:
29. A method for image processing and display, comprising:
a. determining a gaze direction of a first eye of a person viewing an image on a display screen and providing said determined gaze direction to a computer processor;
b. subsequent to ‘a’, based on said determined gaze direction of the first eye, with a computer processor generating a display image for display to the first eye on said display screen from a received digital base image, wherein:
i. a central-vision portion of said display image that corresponds to a portion of the field of view of the first eye that includes said determined gaze direction is either:
unmodified compared to a corresponding portion in said base image; or
modified so that visual characteristics of said central-vision portion of said display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image which modification improves the image quality of said central-vision portion relative to the corresponding portion in said base image, and
ii. a non-central vision portion of said display image that is different from said central-vision portion is either:
unmodified compared to a corresponding portion in said base image; or
modified so that visual characteristics of said noncentral vision portion of said display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image,

wherein as a result of said generating, an image quality of said non-central vision portion of said display image is lower than the image quality of said central-vision portion of said display image; and
c. displaying said generated display image on said display screen so that the first eye of the person views said display image on said display screen,
wherein said non-central portion of said display image is modified so that visual characteristics of said non-central vision portion of said display image are changed compared to corresponding visual characteristics of a corresponding portion in said base image which modification degrades the image quality of said non-central vision portion relative to the corresponding portion in said base image, wherein said modification which degrades the image quality of said non-central vision portion relative to the corresponding portion in said base image includes at least one reduced contrast.
