Patent number: 7924460Abstract: A method for color correction of an image having an insignia portion in a multi-module printer (10). A first color profile is calibrated for a four-color image. A second color profile is calibrated for a four-color image with a transparent toner layer on top of the insignia portion of the four-color image. The image data is then buffered in a color input band buffer (40) and processed through the first (50) and second (60) color profiles in a color management module. The processed image data is stored in an output band buffer (70, 80) corresponding to the image data processed through each color profile. Clear toner input band data stored in a clear toner input band buffer (30) is compared with the processed image data in each output band buffer (70, 80) to select an output signal (100) on a per pixel basis to send to the multi-module printer (10).Type: GrantFiled: August 22, 2007Date of Patent: April 12, 2011Assignee: Eastman Kodak CompanyInventor: Yee S.

Patent number: 7911636Abstract: In a printing method and systems, segments of a first print job are distributed to respective downstream processors and are processed to provide printable frames, which are stored in respective print queues. Each print queue supplies a respective one or more printheads. The printable frames are sequentially printed on a continuously transported receiver. A maximum printing duration of each of the print queues is computed periodically during the printing. The transport speed is regulated to trend the maximum printing durations toward a predetermined baseline. The sending of a second print job to the downstream processors is delayed, while processing of the first print job is completed. The delaying is counter to the regulating and reduces the print queues of the first print job non-uniformly relative to the baseline.Type: GrantFiled: July 25, 2007Date of Patent: March 22, 2011Assignee: Eastman Kodak CompanyInventors: William C. Kuhn, Paul A. Reil, Jeffery L. Ranly

Patent number: 7903168Abstract: In a method and digital camera, initial evaluation images of a scene are captured with the camera. A change in scene brightness between two or more of the evaluation images is computed. When the scene brightness change is outside a predetermined brightness range, a metric of scene-to-capture mismatch in the evaluation images is determined. When the brightness change and the metric are both outside predetermined ranges, the camera is shifted to a second capture state prior to the capturing of one or more additional evaluation images. In either case, a final camera state is determined using available evaluation images and one or more final images are captured with the camera in the final camera state.Type: GrantFiled: April 6, 2006Date of Patent: March 8, 2011Assignee: Eastman Kodak CompanyInventors: Bruce H.
