Patent number: 7443552Abstract: The process of the invention enables the spatial color alterations of a silver image to be taken into account according to one of its main axes (19). The process of the invention enables the altered or faded colors of the silver image to be restored automatically, without depending on the skills of an operator to perform a color restoration treatment. A digital image (12) is divided into adjacent pixel strips (18), arranged perpendicular to the direction (19) according to which the color alteration occurs. For each of these strips (18), optical density distributions of each pixel are calculated and compared with reference optical density values. The process of the invention enables the automatic correction of all the strips (18) comprising the altered pixels, by applying a linear transformation enabling the transformation of the optical density values of the altered pixels, into the optical density values of a pixel strip of least degradation.Type: GrantFiled: June 7, 2003Date of Patent: October 28, 2008Assignee: Eastman Kodak CompanyInventors: Valéry J. Risson, Jean-Fabien Dupont

Publication number: 20070090974Abstract: The invention is to provide a recording process that enables the density of recorded information to be increased on a two-dimensional medium comprising a printing surface, for example a strip of light sensitive film. The process is for a recording system for digital data (1) and a recording medium (7) to record the encoded data, for example a strip of photographic film. The process is used in particular to code data to be recorded at high density, for example the digital data of still or moving images, text, or sound.Type: ApplicationFiled: October 24, 2006Publication date: April 26, 2007Inventor: Jean-Fabien Dupont

Patent number: 7020346Abstract: The present invention is in the field of imaging and more specifically image analysis. An object of the invention is to provide for a method which restores a digitized image or a series of digitized images automatically, by eliminating straight or virtually straight scratches in the images. The method of the invention eliminates scratches in still or animated digital images by using the residual image information in the altered areas of the images. This method can be used in the field of the restoration of films and television documents and for retouching and restoring photographic images.Type: GrantFiled: October 7, 2002Date of Patent: March 28, 2006Assignee: Eastman Kodak CompanyInventors: Jean-Fabien Dupont, Christophe E.

Publication number: 20030048270Abstract: The present invention is in the technological field of imaging and more specifically image analysis. The present invention relates more particularly to an interactive process that lets a user select and validate partially or fully the result supplied by an automatic detection process of digital image data. The invention process enables a display on the display screen of a terminal, one digitized original image, accompanied by a digital image of the graphic representation of candidate zones representative of candidate elements to be extracted from the original image. The user can select and validate the candidate zones or parts of candidate zones that he/she wishes to validate or invalidate. The invention process is used advantageously to renovate images recorded on silver or magnetic supports. The conventional silver supports of these images are generally constituted of photographic film or paper.Type: ApplicationFiled: September 11, 2002Publication date: March 13, 2003Applicant: Eastman Kodak CompanyInventors: Jean-Fabien Dupont, Christophe E.
