Publication number: 20030044063Abstract: A method for processing digital photographic image data includes a method for the automatic detection of red-eye defects. Before the image data are subjected to an elaborate process for the detection of red-eye defects, exclusion criteria are analyzed in the course of an exclusion process, whereby the criteria provide the information to definitively rule out the occurrence of red-eye defects. The red-eye detection process is not carried out if such exclusion criteria are fulfilled.Type: ApplicationFiled: July 9, 2002Publication date: March 6, 2003Inventors: Guenter Meckes, Tobias Damm, Manfred Fuersich, Knut Oberhardt, Klaus Hartmann, Thomas Schuhrke, Gudrun Taresch

Publication number: 20030044177Abstract: In a method for the automatic detection of red-eye defects in photographic image data, image and/or recording data are analyzed independently of one another for several specified indications and/or prerequisites. Thereafter, a value is determined for the presence of the individual indications and/or prerequisites. Thereafter, the determined values are combined for an overall evaluation, and a decision about the presence of potential red-eye defects is made, based upon the overall evaluation. The potential red-eye defects are located, and a decision is made, based upon analysis criteria, as to whether there are, indeed, red-eye defects.Type: ApplicationFiled: July 9, 2002Publication date: March 6, 2003Inventors: Knut Oberhardt, Gudrun Taresch, Friedrich Jacob, Tobias Damm, Hans-Georg Schindler

Patent number: 5870173Abstract: An apparatus for processing film has two processing units and transport rollers for conveying film past the units. One of the units may include a scanning device and the other unit may include a copying device. Alternatively, the two units can comprise a prescanning device and a main scanning device, respectively. The apparatus further has a receiving station for film cartridges and at least one separate receiving station for film which is not confined in cartridges. Film can be fed to the transport rollers from either station.Type: GrantFiled: June 19, 1997Date of Patent: February 9, 1999Assignee: Agfa-Gevaert AGInventors: Knut Oberhardt, Edmund Mangold, Bernhard Lorenz

Patent number: 5248887Abstract: A length of exposed film has a timing track which extends along one of the longitudinal margins thereof. The timing track includes a begin segment having a first width, an end segment having a different second width and a grating between the segments. The grating consists of alternating light and dark segments having a uniform width different from the widths of the begin and end segments. The two longitudinal margins of the film are scanned by respective sensors as the film advances towards a film processing apparatus. Whenever a segment passes by a sensor, the width of the segment and its position in the timing track are recorded. Since the widths of the begin and end segments differ from the width of the grating segments, the position of the begin or end segment relative to the grating can be established. This information, combined with a knowledge of which sensor detected the timing track, makes it possible to determine the orientation of the film.Type: GrantFiled: May 1, 1992Date of Patent: September 28, 1993Assignee: AGFA-Gevaert AktiengesellschaftInventor: Knut Oberhardt

Patent number: 5155524Abstract: A photographic copier has an adjustable masking device for masking a master to be reproduced. To determine whether masking is required and, if so, the degree of masking, the density of the master is measured and is then forwarded to a logic circuit which can make the determination. In a first mode of operation, masked and unmasked images of the master are displayed side-by-side on a pair of monitors so that an operator can make adjustments to the mask calculated by the logic circuit. The operator here controls the copying cycle. In a second mode of operation, the copying cycle is automated and the logic circuit decides whether masking is required by calculating a degree of masking and comparing the degree of masking with a relatively low reference value set by the operator. The master is copied without a mask when the calculated degree of masking is less than the reference value. If a copy made by masking is unsatisfactory, the operator can adjust or deactivate the logic circuit and make a new copy.Type: GrantFiled: January 16, 1992Date of Patent: October 13, 1992Assignee: AGFA-Gevaert AktiengesellschaftInventors: Knut Oberhardt, Wolfgang Zahn

Patent number: 5029369Abstract: The tongue at the free end of a safety belt in a motor vehicle is releasably connected to the buckle by a coupling member which can be disengaged from the tongue by a reciprocable release member. The latter can be depressed by hand to thereby pivot (either entirely or in part) prior to completing a translatory movement which results in disengagement of the coupling member from the tongue. If the buckle is abruptly accelerated during an accident, the release member tends to carry out the translatory movement without a preceding pivotal movement whereby a stationary blocking element intercepts a blocking element on the release member and holds the latter against movement to a position in which the coupling member is caused or permitted to release the tongue. Alternatively, the release member is mounted for translatory movement to thereby disengage the coupling member from the tongue.Type: GrantFiled: October 19, 1989Date of Patent: July 9, 1991Assignee: Autoliv-Kolb GmbH & Co.Inventors: Knut Oberhardt, Walter Notar
