Method and system for displaying an image

1. A method for transmitting a compressed digital image to a display that is viewed by a human observer having a first point of gaze and then a second point of gaze, comprising the steps of:

sending first data of the digital image to fill all regions of the display with a minimum resolution level of image information;

15. A method for transmitting a compressed digital image to a display that is viewed by a human observer having a point of gaze, comprising the steps of:

sending first data of the digital image to fill all regions of the display with a minimum resolution level of image information;

determining the point of gaze of the human observer; and

then sending second data of said digital image to refine image details, starting with data that corresponds to said point of gaze and progressing outward away from said point of gaze.

16. The method of claim 15 , wherein said determining further comprises determining the observer's point of gaze with an eye tracking device.

17. The method of claim 1 , wherein said determining further comprises analyzing the image content to determine the point of gaze.

18. A method for transmitting compressed image data to a display that is viewed by a human observer having a point of gaze, comprising the steps of:

sending first data to fill all regions of the display with a minimum resolution level of image information;

determining the point of gaze; and

sending second data to refine image details, starting with data that corresponds to said point of gaze and progressing outward away from said point of gaze;

wherein said determining further comprises measuring points of gaze of a plurality of viewers of an image and determining said point of gaze as a function of the measured points.

19. A method for transmitting compressed image data to a display that is viewed by a plurality of human observers, each having a point of gaze, comprising the steps of:

sending first data to fill all regions of the display with a minimum resolution level of image information; and

sending second data to refine image details, as a function of the points of gaze of the plurality of human observers, in alternation, starting with data that corresponds to said points of gaze and progressing outward away from the respective said points of gaze.

20. The method of claim 19 , wherein the compressed image data is compressed using the JPEG 2000 compression standard to contain one or more tiles and one or more precincts; and said sending is by precinct.

21. The method of claim 1 , wherein said sending steps each include decompressing the respective said data of the digital image.

22. The method of claim 8 , wherein the compressed digital image is compressed using the JPEG 2000 compression standard to contain one or more tiles and one or more precincts.

23. The method of claim 22 , wherein the second data represent precincts from one or more resolution levels that are also prioritized in order of closest distance to furthest distance from the point of gaze.
