Yusheng T Tsai: Digital compression method and system with improved coding efficiency. Eastman Kodak Company, Edward Dugas, November 27, 1990: US04974078 (175 worldwide citation)

In a method for creating a scan sequence for a single chip color camera an analysis of typical images, captured through a color filter array, is performed to determine an optimal scan sequence for the particular array and/or the typical images. The images, after being digitally captured, are separat ...

Christopher M Dobbs, Robert M Goodwin: Localized image recoloring using ellipsoid boundary function. Eastman Kodak Company, Edward Dugas, July 14, 1992: US05130789 (135 worldwide citation)

A mechanism for recoloring a color image defines a spatial region within the image (such as the pupil of the eye) a color characteristic of which (e.g. the `red-eye` phenomenon) is to be selectively modified. To determine whether the color of an image sample within a spatial region is to be modified ...

Cynthia S Bell: Electronic camera with proofing feature. Eastman Kodak Company, Edward Dugas, May 2, 1989: US04827347 (135 worldwide citation)

A camera comprised of an electronic imager and a plurality of display/frame stores. Each of the plurality of display/frame stores is individually selectable, for example, by a transparent touch-sensitive media positioned over the plurality of display stores. The selection acts to either retain or to ...
